Revised Canadian IMSI Assignment Guideline to include Full
OUTCOME: NON-CONSENSUS
RELATED TASK(s) #:
BACKGROUND:
On 05 May 2015 the CRTC issued Telecom Regulatory Policy CRTC 2015-177, Regulatory
framework for wholesale mobile wireless services.
In Paragraph 159 of Telecom Regulatory Policy CRTC 2015-177, the CRTC noted that
Mobile Virtual Network Operators (MVNOs) are not currently eligible to acquire a Mobile
Network Code (MNC).
159. Mobile network codes (MNCs) in Canada are assigned by the Canadian
Numbering Administrator pursuant to the Canadian International Mobile
Subscriber Identity (IMSI) Guideline (the Guideline). The Guideline was developed
by the Canadian Steering Committee on Numbering (CSCN) and approved by the
Commission. The Guideline requires that an applicant for an MNC hold a spectrum
licence from Industry Canada. Thus, MVNOs cannot acquire MNCs.
MVNOs are not eligible for MNCs based on Section 7 of the current Canadian International
Mobile Subscriber (IMSI) Guideline.
Accordingly, in Paragraph 162 of Telecom Regulatory Policy CRTC 2015-177, the CRTC
has directed the CSCN to amend the IMSI Guideline to permit assignment of MNCs to full
MVNOs by 6 July 2015.
162. The Commission hereby directs the CSCN to (i) amend the Guideline to allow
full MVNOs to acquire MNCs, and (ii) submit the amended Guideline for
Commission approval by 6 July 2015. [Emphasis added]
In the process of updating the IMSI Guideline, the CSCN faced some challenges with the
Commission’s term “full MVNO”. The definition that was provided in TRP 2015-177 was
not specific enough for the purposes of the IMSI Guideline. Further, the term “full MVNO”
is not a defined term in the wireless industry.
Due to international and national wireless industry 2-digit limitation, the CSCN has been
carefully monitoring the assignment and usage of MNCs for a period of time. To date in
Canada, 45 MNCs are assigned and 56 remain for assignment based on the current
Guideline. Appendix 1 of the Guideline also outlines further limitations (2-digit MNCs) to
availability. If the MNC inventory is exhausted, a new Mobile Country Code is required
and the implementation could be costly on the industry.
The CSCN has drafted a revised Guideline that permits assignment of MNCs to full MVNOs
but was unable to come a consensus on what the definition of a full MVNO should be in
the Guideline.
1
ISSUES:
Revised guideline excluding the “Full MVNO” definition (consensus):
Under direction from Telecom Regulatory Policy CRTC 2015-177, the CSCN has
modified the Canadian International Mobile Subscriber (IMSI) Guideline to permit
the assignment of MNCs to Full MVNOs. The CSCN was able to come to a
consensus on the whole document except the definition of a Full MVNO.
CRTC qualify Full MVNOs and create and maintain registration list (consensus):
The CSCN does not believe it should be the responsibility of either the CSCN or
the CNA to determine whether an MVNO meets the requirements to be considered
a Full MVNO. Accordingly, the CSCN recommends that the CRTC qualify all eligible
registrants and create and administer a registration list of organizations that meet
the requirements of a Full MVNO. This will allow the CNA, when assigning MNCs,
to quickly identify whether an organization is eligible for assignment of MNCs. This
is a similar reference process that the CNA uses for identifying if a CO code
applicant qualifies as a Competitive Local Exchange Carrier or Wireless Service
Provider.
Definition of a “Full MVNO” (non-consensus): The four positions represented are below.
2
POSITION 1 (Cogeco):
1. At the last meeting of the CSCN on TIF 94, dated 5 June 2015, the participants came
to a non-consensus with respect to the definition of “Full MVNO” to be included in
the Glossary, section 15.0 of the Canadian International Mobile Subscription Identity
(IMSI) Guideline. A streamlined definition (Definition 1) and an explicit definition
(Definition 2) of full MVNO have been proposed stating the following:
Full MVNO
DEFINITION 1: An MVNO that is registered with the CRTC as a Full
MVNO.
DEFINITION 2: An MVNO that is registered with the CRTC as a Full
MVNO. To register with the CRTC as a Full MVNO, an MVNO must be
able to provide mobile wireless services to consumers using core
network hardware (e.g. switches, routers) separate from all WSPs, and
its own service profile management system (eg. Home Location
Register [HLR], Home Authentication, Authorization, and Accounting
[AAA], Home Subscriber System [HSS]), all of which must be located in
Canada.
2. Cogeco is in favor of Definition 1 for the following reasons. For the purpose of this
Guideline, Cogeco submits that this proposed streamlined definition is not only
consistent with the proposed modification to Section 2.11 of the Guideline which
reflects the description of a full MVNO used in TRP 2015-1772, but enunciates
without ambiguity that the registration requirement with the CRTC is the determining
element to identify a full MVNO eligible to obtain a Mobile Network Code (MNC).
3. Furthermore, Cogeco submits that it is neither the role of the CSCN to define which
requirements would permit to identify a full MVNO, nor the role of the Canadian
Numbering Administrator (CNA), i.e., the Canadian IMSI Administrator, based on
such a definition, to determine which entity is eligible to obtain or not an MNC.
4. As noted in paragraph 160 of TRP 2015-177, the possibility of acquiring its own
MNC is critical to ensuring that a full MVNO can commercially operate in the retail
market independently of its host wireless carrier. Since this component is not a
requirement for an MVNO operating as a branded reseller, the Commission directly
The proposed modification to Section 2.1 of the Guideline states that “A Full MVNO is an MVNO
who supplies most of the components of the network it uses to provide services apart from the
Radio Access Network (RAN) and is registered with the CRTC as a Full MVNO”
2 Paragraph 43 states: “An MVNO that supplies most of the components of a network apart
from the RAN is referred to in this decision as a “full MVNO.” Branded resellers provide
marketing services, distribution channels, and billing services, but rely on wireless carriers for the
rest of their business, including the operation of the network. While MVNO models vary, they all
require access to the RAN of a wireless carrier.” (Emphasis added)

referred to the full MVNO category in the policy decision where it explained the
relevance of amending the Guideline for the assignment of MNCs.3 In fact, for the
understanding of the decision, it was not necessary to have a technical definition of
full MVNO. Further, although the Commission directed the CSCN to amend the
Guideline to allow full MVNOs to acquire MNCs, it is very significant to note that
the Commission did not order the CSCN to propose such a definition.
5. In any event, Cogeco submits that it is the role of the CRTC to determine the
requirements that should be met by a wireless service provider to be considered a full
MVNO and be allowed to acquire an MNC. To this end, Cogeco reiterates that the
registration process enunciated in proposed Definition 1 is appropriate and sufficient.
6. Furthermore, in TRP 2015-177, Cogeco notes that the Commission declined to
establish a regulatory framework mandating the provision of MVNO access services,
and continued relying on commercial negotiations to support the emergence of
MVNOs, including full MVNOs. Further, the Commission used “its existing powers
to take action to reduce certain barriers faced by MVNOs to facilitate, and allow
more flexibility in, their commercial negotiations with wireless carriers” (Emphasis
added), expecting that the removal of MVNO restrictions in wholesale roaming
arrangements and the possibility for full MVNO to acquire an MNC “should also
encourage the emergence of a competitive market for wholesale MVNO access.”4
7. Since the Commission is relying mainly on market forces to foster the emergence of
full MVNOs, for consistency purposes, Cogeco submits that the registration process
for full MVNO should be as streamlined as possible.
8. Therefore, in order to be registered as a full MVNO with the Commission, Cogeco
proposes a two-step process. In the first step, a wireless service provider would
simply have to notify the Commission, in writing, that it is negotiating a wholesale
full MVNO access arrangement with a wireless carrier. Based on this notification, the
wireless service provider would be recognized and registered as a “proposed full
MVNO” by the CRTC and would thus be allowed to submit an MNC application to
be reviewed and processed by the CNA.
9. In the second step, the proposed full MVNO would inform the Commission, in
writing, that it has concluded a wholesale full MVNO access agreement and therefore
is qualified to be registered as a full MVNO with the CRTC. Consequently, based on
this registration, the CNA would immediately assign the requested MNC to the full
MVNO.

POSITION 2 (Rogers):
Background
In CSCN TIF 94, a non-consensus has arisen over whether or not to include a detailed
definition of the CRTC term, “Full MVNO,” which appears in Telecom Regulatory Policy
2015-177, paragraph 43. It states:
“MVNOs also rely on some or all components of a wireless carrier’s network, including the RAN,
to provide retail services. An MVNO that supplies most of the components of a network apart
from the RAN is referred to in this decision as a “full MVNO.” Branded resellers provide
marketing services, distribution channels, and billing services, but rely on wireless carriers for the
rest of their business, including the operation of the network. While MVNO models vary, they all
require access to the RAN of a wireless carrier.”
To facilitate preparation of the non-consensus report, Rogers proposes the following text
be used in the preparation of the non-consensus report:
Full MVNO Definition
Rogers proposes the following definition of “Full MVNO” be used in the Glossary of the
IMSI Guidelines:
A Full MVNO is a MVNO that must register with the CRTC and demonstrate that it
has core network hardware platforms separate from all WSPs (eg. switches, routers)
and a service profile management system (eg. Home Location Register [HLR], Home
Authentication, Authorization, and Accounting [AAA], or Home Subscriber System
[HSS]); own, operate or have access to transmission facilities to provide mobile
wireless services to consumers; and handle its own network routing. All platforms are
within Canada.
5
Rationale
In Telecom Regulatory Policy 2015-177, the Commission ratifies the use of the term
“Full MVNO” however the definition of “Full MVNO” in TRP 2015-177 is somewhat shy of
what is required by the Canadian Numbering Administrator (CNA) and others to easily
determine whether or not the applicant of a Mobile Network Code (MNC) is a Full MVNO
or not.
Rogers believes that a complete definition is required to reduce ambiguity. Ambiguity is
the enemy of any guideline. Further, the Telecom Act5 lists among its objectives:
“7 (a) to facilitate the orderly development throughout Canada of a telecommunications
system that serves to safeguard, enrich and strengthen the social and economic fabric of
Canada and its regions;”
If a clear and detailed definition of “Full MVNO” is not implemented in the IMSI
Assignment Guideline, MVNO organizations may use this ambiguity to argue that they
qualify as a Full MVNO. Providing a clear and unambiguous definition of “Full MVNO”
will facilitate the orderly development of telecommunications systems throughout
Canada.
A clear and detailed definition of “Full MVNO” will ensure that MNCs are assigned to
only those parties that truly match the Commission’s definition and intention of a “Full
MVNO.” This in turn will create a mechanism of efficient distribution of the Canadian
MNCs. Distributing MNCs on an inefficient basis will lead to premature exhaust of the
Canadian MNC resource which will force the entire industry into a costly MNC relief
planning process.
Rogers also supports the suggestion that a MVNO must register with the CRTC in order
to become a Full MVNO. A Full MVNO is basically a facilities-based WSP without a
Radio Access Network (RAN). A Full MVNO should therefore be subject to the same
regulations and qualification requirements as a complete WSP. This is consistent with
the Telecom Act’s Canadian Telecom Policy6 Objective 7 (d), “to promote the ownership
5

http://laws-lois.justice.gc.ca/PDF/T-3.4.pdf
6
and control of Canadian carriers by Canadians” and PART II of the Telecom Act,
“ELIGIBILITY TO OPERATE; Canadian Ownership and Control.” Allowing a MVNO to
become a Full MVNO without Canadian Ownership and Control requirements would
facilitate organizations with nefarious intentions of skirting Canadian laws and
regulations by claiming that since they are outside of the country, they are not required
to comply with Canadian laws and regulations. Also, if the HLR or HSS are located in
foreign countries, it may subject the identity of Canadian subscribers to the laws of
investigation of foreign countries which may not be compatible with Canadian laws. For
these reasons, a MVNO seeking qualification to become a Full MVNO must register with
the CRTC, meet Canadian Ownership and Control requirements, and locate its network
platforms within Canada.

POSITION 3 (Bell):
Background
In Telecom Regulatory Policy 2015-177, at paragraph 162, the Commission required the
CSCN to amend the IMSI guideline to allow “full MVNOs” to acquire Mobile Number
Codes (MNCs).
The Commission provides a short description of the term “full MVNO” at paragraph 43:
MVNOs also rely on some or all components of a wireless carrier’s network,
including the RAN, to provide retail services. An MVNO that supplies most of
the components of a network apart from the RAN is referred to in this
decision as a “full MVNO.” Branded resellers provide marketing services,
distribution channels, and billing services, but rely on wireless carriers for the rest
of their business, including the operation of the network. While MVNO models
vary, they all require access to the RAN of a wireless carrier. (emphasis added)
In the process of updating the IMSI guideline, as directed by the Commission, the CSCN
faces a significant challenge. It is important for the IMSI guideline to clearly and
unambiguously define the specific criteria that applicants for MNCs must meet in order to
be eligible to obtain these scarce numbering resources. This is so that the Canadian
Numbering Administrator (CNA) can appropriately and efficiently assign MNCs only to
those eligible entities and refuse those that are not.
Unfortunately, the Commission’s definition of a “full MVNO” is inexact. The words “most
of the components” do not provide sufficient certainty for the CSCN to determine
whether or not an MVNO qualifies as a “full MVNO” to obtain MNCs.
Cogeco has advocated that the CSCN should not attempt to clarify the current ambiguity
regarding “full MVNO” status is that the applicant need only register as a “full MVNO”
with the Commission.7 We disagree with this approach because of the risks it poses as
explained below.
7 See Cogeco contribution for TIF 94submitted to CSCN 29 May 2015 and Minutes of meeting 5 June 2015.
8
Instead, we recommend three things: i) that a clear and complete definition of a “full
MVNO” be approved by the Commission and included for reference in the IMSI
guideline, ii) that the Commission manage a process where entities are required to
register as “full MVNOs” and iii) that the Commission assesses whether the entities that
claim to register as “full MVNOs” actually meet the required criteria before they are listed
on its website.
Rationale
The need for a clear, unambiguous definition of “full MVNO”
A clear definition is necessary for prospective code applicants to understand the criteria
to be met in order to be eligible to apply for and obtain MNCs. The CNA is not in a
position to determine who should get the codes without sufficiently clear criteria. There
is no consensus within the CSCN on what “full MVNO” means or implies. A complete
and easy to administer definition is required to eliminate the current ambiguity. Without
a clearly defined, Commission-approved definition, the ambiguity will continue and will
leave the CNA to interpret and assign MNCs without direction.
A clear and detailed definition of “full MVNO” ensures that MNCs are assigned to only
those entities that align with the Commission’s intention with respect to “full MVNOs.” In
TRP 2015-177, the Commission puts emphasis on the importance of encouraging
investment in wireless networks and the need to break down barriers so that MVNOs
can participate in this market. The Commission made a conscious decision to
distinguish “full MVNOs” when it allowed only these entities to obtain MNCs to
encourage more wireless investment and provide these MVNOs more flexibility to
participate in the delivery of wireless services. Cogeco itself acknowledged this point at
paragraph 114 of the TRP.
Cogeco submitted that the entry of MVNOs in the market would increase the
amount of investment in the telecommunications industry, since it would be
necessary for these service providers to make substantial investments in facilities
and operational systems to operate as full MVNOs.
MNCs are limited numbering resources and must be managed efficiently
9
All numbering resources must be managed efficiently so that a sufficient quantity
remains available for use, particularly in the case of MNCs, where this resource is
much more constrained compared with other numbering resources. The MNCs have a
very limited inventory pool which is due to a known International routing limitation related
to GSM and CDMA systems. This limitation is recognized by the International
Telecommunications Union and built into the US IMSI guideline as well as the Canadian
IMSI guideline at Appendix 1. In the industry, certain GSM and CDMA systems are only
able to handle two digits, which in practice means that not all the MNCs in the inventory
within a country code can be assigned. For example, if the MNC 220 is assigned to Bell
Mobility, then the MNC 221 cannot be assigned to another entity as certain systems will
only see “22” and would confuse which service provider is associated with calls. In
Canada, there is only one country code and therefore the maximum number of MNCs
that can be assigned is under 100 (some numbers cannot be assigned) of which
approximately 50 are already assigned. For years now, the CSCN has been actively
monitoring this resource and discussing this topic multiple times each year to ensure the
inventory continues to be adequate for all the stakeholders.
If MNCs were to be assigned without any restrictions on which entities qualify as a “full
MVNO”, including resellers, the number of MNCs could very quickly be exhausted.
Once the inventory is depleted (and even well before that time) a new country code
would need to be implemented for Canada. This will impose very significant investments
for all of the wireless industry so that respective IS/IT systems are updated concurrently
in order to be able to address a new country code. Therefore, MNCs should not be
assigned to all MVNOs, including those that are only reselling services, as this would
lead to a premature exhaust of the MNC inventory. It makes no sense to impose these
costs on all the entities that need these codes particularly for entities who fall short of
being “full MVNOs” that do not invest in the wireless networks.
Requiring “full MVNOs” to register with the Commission
We consider that the administrative simplicity associated with
assigning other
numbering resources, such as Central Office (CO) codes, provides a useful guide in this
case for “full MVNOs”. In the case of CO codes, the CNA is able to either rely on simple
validation elements, such as a Commission letter authorizing a CLEC to operate in an
area, or the Commission’s website that lists those CLEC authorized to operate as
CLECs. This information provides the CNA with the certainty to determine if a CO code
applicant meets the eligibility requirement for a CO code. For MNCs, the same logic
should apply and “full MVNOs” registered with the Commission on a distinct “full MVNO”
list would enable the CNA to determine whether an MNC can be assigned to a specific
entity claiming to be an MVNO. This approach is transparent for the industry and should
10
be relatively easy to implement. It would also enable the CNA to perform its duties and
assign MNCs in an efficient and orderly manner.
The need for Commission validation
For the same reason that the Commission qualifies other types of entities, like LECs with
specific rules and criteria, “full MVNOs” should similarly have a clearly articulated and
easy to administer set of criteria and be qualified by the Commission. A neutral party
like the Commission has the ability to examine confidential information and has the
technical expertise to confirm whether an entity meets the criteria of a “full MVNO.”
“Full MVNO” Definition
Some CSCN parties have proposed a definition for inclusion in the IMSI guideline.
Although we fully support having the definition of a “full MVNO” included in the IMSI
guideline for reference purposes (since not all parties would necessarily know where to
look for this information on the Commission’s website) we nevertheless believe that
simply having a definition in the IMSI guideline is not sufficient. The status of a “full
MVNOs” must be validated using a specific, easy to administer set of criteria. The
definition in the IMSI guideline could be a simple summary but the criteria to be used to
validate whether an entity is a “full MVNO” is ultimately what is most important.
To assist the Commission in validating “full MVNO” status, we propose below the
following criteria. For greater certainty, under our proposed approach, an entity would
not qualify as a “full MVNO” unless it satisfies all three of the following criteria:
1) Owns and operates core network hardware separate from all WSPs (e.g. switches,
routers, etc.)
Rationale: the “full MVNO” must be able to demonstrate that it owns a core
network and is not relying on the core network of another carrier.
11
2) Owns and operates a service profile management system (a Home Location Register
(HLR), or a Home Authentication, Authorization, and Accounting (AAA), or a Home
Subscriber System (HSS))
Rationale: the “full MVNO” must be able to demonstrate that it has its own
service profile management system.
3) Handles its own network routing
Rationale: the “full MVNO” must be able to demonstrate that it is handling its own
network routing and is not relying on routing by another carrier.
Conclusion
In conclusion, Bell’s resolution of the “full MVNO” issue embodies the following three
principles: i) the Commission adopts a clear and complete definition of a “full MVNO”
that is included for reference in the IMSI guideline, ii) that the Commission manage a
process where entities are required to register as “full MVNOs” and, iii) that the
Commission assesses whether the entities that claim to register as “full MVNOs” actually
meet the required criteria before they are listed on its website. Our recommended
definition of “full MVNO” is an entity that meets each of the following three criteria:
A “full MVNO”:
1) Owns and operates core network hardware separate from all WSPs (e.g.
switches, routers, etc.); and,
2) Owns and operates a service profile management system (a Home Location
Register (HLR), or a Home Authentication, Authorization, and Accounting (AAA),
or a Home Subscriber System (HSS)); and,
3) Handles its own network routing.
12
POSITION 4 (SaskTel):
Full MVNO Definition: A "Full" MVNO utilizes a Carrier Wireless Service providers
network through a negotiated arrangement to provide its own managed
telecommunication services to the general public. It is differentiated from Resellers
and Rebillers by its requirement to own certain network elements to manage the service
received by its end customers.
SaskTel notes that the definitions proposed by the other parties do not incorporate the
ITU requirement from E.212 Appendix B, Paragraph 2, that Mobile Network Codes
(MNC)'s are only to be assigned to, and used by public networks offering public
telecommunication services.
SaskTel has focused its proposed definition on the outcome of the requirement of being a
Full MVNO. The Full MVNO must use network elements to provide and manage its own
service independent of the Carrier Wireless Service Provider's agreement. This
interpretation is informed by the Commission's Notice of Consultation (NC) 2014 - 76
paragraph 5 (requirement "to enable MVNO's to offer services") and Telecom Regulatory
Policy (TRP) 2015 -177, Paragraph 43, ("supplies most of the components apart from the
RAN"). SaskTel considers that the specific network elements are less relevant, (as they
change over time), than the requirement which is to use MVNO owned network resources
to deliver and manage the MVNO services.
SaskTel notes the International and National industry are and have been concerned about
the potential exhaust of the MNC two digits codes. The impact of such an exhaust,
driven by industry factors such as additional technologies (which would require a
significant number of codes for existing providers), and/or a large number of new
participants such as MVNO's could quickly exhaust the remaining MNC unassigned
codes. The consequence of the exhaust would be the implementation of an additional
country code.
The addition of a Wireless Country Code would be the first for the Canadian Wireless
Service Providers. Although the real scope could not realistically be determined, SaskTel
expects the implementation expense to exceed the cost a carrier would experience in a
"standard" NPA exhaust. Despite best industry efforts of managing the exhaust, the
country code implementation time line has the potential to restrict competition by
MVNO's and WSP's due to the carrier requirement to modify their existing operational and
billing systems to accept the new country code.

CONCLUSIONS: The CSCN created a draft version of the Canadian International Mobile
Subscriber (IMSI) Guideline that was acceptable to all parties except for the definition of
a Full MVNO included in the Guideline.
RECOMMENDATIONS: The CSCN recommends that the CRTC review the Canadian
International Mobile Subscriber (IMSI) Guideline as included and consider the four
positions for the included definition of a Full MVNO.
The CSCN recommends that the CRTC decide on the definition of a Full MVNO to be
included in the Guideline.
The CSCN recommends that the CRTC qualify all eligible registrants and create and
administer a registration list for Full MVNOs.
The CSCN recommends that the CRTC, after determining a final definition for Full MVNO,
approve the revised Canadian International Mobile Subscriber (IMSI) Guideline with the
final Full MVNO definition.

Introduction
The Canadian Steering Committee on Numbering (CSCN) developed this Guideline for
use in Canada. It becomes effective upon review by the CRTC Interconnection Steering
Committee (CISC) and approval by the Canadian Radio-television and
Telecommunications Commission (CRTC).
In Canada, the Canadian Numbering Administrator (CNA) (hereafter referred to as the
“IMSI Administrator”) undertakes the primary administrative functions for all International
Mobile Subscription Identity (IMSI) resources. The CNA administers IMSI resources in
accordance with Guidelines developed by the CSCN and approved by the CRTC. The
administration of IMSIs in Canada is conducted under the regulatory authority of the
CRTC and Industry Canada.
2.0
Purpose and Scope
This document contains procedures for the assignment and use of IMSIs for Canadian
Wireless Service Providers (WSP), Wireless Competitive Local Exchange Carriers
(WCLEC), satellite carriers, certain public safety related associations, and ‘Full’ Mobile
Virtual Network Operators (MVNO).
2.1
For the purpose of this Guideline, a WSP or WCLEC is defined as a Canadian
entity authorized by Industry Canada pursuant to the Radiocommunication Act to
provide two-way common carrier wireless mobility communications service to the
public. Examples of WSPs and WCLECs include Cellular, Personal
Communications Services (PCS), Enhanced Specialized Mobile Radio (ESMR),
and Mobile Satellite Services (MSS). A Full MVNO is an MVNO who supplies
most of the components of the network it uses to provide services apart from the
Radio Access Network (RAN) and is registered with the CRTC as a Full MVNO.
2.2
This Guideline pertains to the entire Canadian IMSI resource. The IMSI
Administrator administers only the Mobile Network Code (MNC) segment of the
IMSI. The combination of the Mobile Country Code (MCC) and MNC is referred
to as the Home Network Identity (HNI) and identifies the home mobile network of
a subscription. The remaining segment of the IMSI, the Mobile Subscription
Identification Number (MSIN), is directly administered by the network operator to
whom the MNC is assigned.

The format of the IMSI in North America is:
Mobile Country
Mobile Network
Code (MCC)
Code (MNC)
3-digits
3-digits*
Mobile Subscription Identification
Number (MSIN)
9-digits*
Home Network Identity
(HNI)
National Mobile Subscription Identity
(NMSI)
International Mobile Subscription Identity
(IMSI)
*Note: See Appendix 1 concerning 2- and 3-digit MNCs.
4.5
The IMSI format in Canada is a fixed 15-digit length -- the maximum allowable by
Recommendation E.212. Each IMSI contains an MCC, an MNC, and an MSIN.
The MCC and MNC combine to form the HNI. The MNC and MSIN together form
the National Mobile Subscription Identity (NMSI). MSINs are administered
directly by the wireless network operator to whom the MNC is assigned.
4.6
The function of the MCC is to identify the domiciliary country of a mobile
subscription. Some MCCs are used to identify international operators, e.g.
satellite systems providing service to aircraft, maritime or land-based mobile
subscriptions across or between multiple countries. By analyzing the MCC, a
foreign visited wireless network can determine the country or international
-3-

Approved: d mmm 2015
operator from which the mobile subscription originated and in which its home
mobile network resides.
According to ITU-T Recommendation E.212, an MCC is three digits in length.
MCCs other than a test MCC are in the format NXX, where N equals any of the
digits 2-9, and X equals any of the digits 0-9. MCCs are assigned by the ITU in
response to formal requests from recognized national administrators of
ITU-member countries, and more than one MCC may be assigned to a country.
In Canada, the recognized national administrator for ITU resources is Industry
Canada. The MCC currently assigned to Canada is 302.
4.7
The function of the MNC is to identify the home mobile network, within the
country associated with the MCC, of the visiting mobile subscription. The visited
mobile network uses the MCC-MNC combination to determine the home mobile
network of the visiting mobile subscription that is requesting service.
Per ITU-T Recommendation E.212, MNCs may be two or three digits in length,
the choice being a national matter. In North America MNCs are three digits in the
format XXX, where X equals any of the digits 0-9. The three digit maximum is
necessary so that, when combined with the 3-digit MCC, the visited network
need not analyze more than six digits to determine the home mobile network of
the visiting mobile subscription. The XXX format provides one thousand MNCs
(000-999) for each MCC. (See Appendix 1 for “temporary” GSM - based
limitations on MNC assignments.)
4.8
The function of the MSIN is to uniquely identify a mobile subscription within its
home mobile network.
MSINs in Canada are nine digits in length and in the format XXXXXXXXX, where
X equals any of the digits 0-9. ITU-T Recommendation E.212 limits IMSI length
to a 15-digit maximum. Since the Canadian IMSI format includes a 6-digit MCCMNC, a 9-digit MSIN is the maximum allowable. The nine digit format provides
one billion MSINs per MNC.
4.9
The NMSI contains the MNC followed by the MSIN and is a fixed twelve digit
length in Canada. It is the national portion of the IMSI, i.e. excluding the MCC. Its
length and format are determined nationally within the constraints of ITU-T
Recommendation E.212.
5.0
Assumptions and Constraints
This Guideline is based on the following assumptions and constraints:
-4-
International Mobile Station Identity (IMSI) Assignment Guideline
Approved: d mmm 2015
5.1
This Guideline shall permit the effective and efficient management of IMSIs as a
finite resource.
5.2
The function of the IMSI Administrator will be performed by the CNA.
5.3
This Guideline for IMSI assignments shall remain in effect until there is regulatory
approval to change it.
5.4
This Guideline does not describe the method by which IMSIs are transmitted
between and processed by networks. Network interworking arrangements are
contained in other standards, documents, or business agreements.
6.0
Assignment Principles
The following assignment principles will apply to the assignment of MNCs by the IMSI
Administrator and the use of IMSIs by assignees:
6.1
MNCs are to be assigned and used in accordance with this Guideline.
6.2
On receipt of a valid application, the IMSI Administrator will assign an initial MNC
to the applicant. In exceptional circumstances, in order to accommodate certain
technological or operational constraints, e.g., where separate facility-based
wireless networks are provided by a WSP or WCLEC, the IMSI Administrator can
assign an additional MNC in the XX0 format. In the event that an applicant
submits an application for a third MNC in the XX0 format, the IMSI Administrator
shall consult with CRTC staff before making an assignment decision. If an MNC
in the XX0 format is currently assigned to a wireless Carrier, then MNCs in the
XXX format within that MNC can be assigned to that wireless Carrier without
consultation with CRTC staff.
6.3
The 3-digit MNC is to be assigned so as to uniquely identify the home mobile
network of the service user.
6.4
An MSIN is assigned by a wireless network operator to a mobile subscription. An
individual IMSI may only be assigned to a single subscription; however, more
than one IMSI may be assigned to a mobile user.
6.5
IMSIs and MNCs shall be assigned to permit the most effective and efficient use
of a finite resource in order to defer, as long as practical, the need to request
additional MCC resources.
-5-
International Mobile Station Identity (IMSI) Assignment Guideline
Approved: d mmm 2015
6.6
IMSIs are a public resource. The assignment of any portion of an IMSI (i.e.,
MNC, MSIN) does not imply ownership of the resource by either the entity to
which it is assigned or by the entity performing the administrative function.
6.7
Should an assignee transfer control of its network operation through acquisition
or merger to another operator, then the use of the assigned MNC is transferable
to that operator.
6.8
The IMSI Administrator will:
a)
Assign MNCs in a fair, timely and impartial manner to any applicant
that meets the criteria for assignment contained in this Guideline.
b)
Assign MNCs on a first-come, first-served basis from the available
pool of unassigned MNCs.
c)
Make all assignments based on the procedures in this Guideline.
d)
Treat sensitive information received from applicants as proprietary and
confidential.
e)
Assign MNCs to applicants authorized by Industry Canada or the
CRTC to provide service on an experimental basis. In the event the
applicant is eligible, based on section 6.2 above, and is subsequently
authorized to provide the service on a regular basis, the assignee may
be permitted by the IMSI Administrator to retain the same MNC
assigned for the experimental operation.
f)
MNCs 990 to 999 have been set aside for experimental purposes not
initially requiring regulatory approval. Should the experimental period
exceed one year, the temporary assignee is required to re-apply for
the use of the MNC, three months in advance of the expiration of the
one year timeframe.
6.9
Information that is requested of applicants in support of an MNC application shall
be uniform and kept to a minimum.
6.10
Assigned MNCs should be deployed as soon as possible, but no later than
twelve months after initial assignment. If the assignee can demonstrate that an
assigned MNC has not been deployed solely due to delays beyond its control,
the time period can be extended for up to 90 days. At the discretion of the IMSI
Administrator, up to three additional 90-day extensions may be granted.
6.11
An entity that is denied an MNC assignment or extension under this Guideline
has the right to appeal that decision in writing to the CRTC with a copy provided
to the IMSI Administrator.
6.12
An MNC recovered or returned to the IMSI Administrator’s pool will be aged for a
period of not less than one year, from the date of return to the MNC pool, before
reassignment.
-6-
International Mobile Station Identity (IMSI) Assignment Guideline
Approved: d mmm 2015
6.13
Applicants for MNCs must comply with all applicable Canadian regulatory
requirements in regards to the provisioning of wireless network services.
7.0

to efficiently and effectively administer/manage a limited resource through
code conservation, and
to eliminate or delay the exhaust potential for the MCCs currently
assigned to Canada.
To promote the efficient and effective use of numbering resources, audits of
MNC assignments may be performed to ensure consistent compliance with these
Guidelines.
12.0 MCC Relief Planning
12.1
When 70% of the MNCs for a given MCC have been assigned, the IMSI
Administrator will inform the CSCN, CRTC staff, Industry Canada and the ITU
Study Group 2 Chair that MCC 302 assigned to Canada is approaching exhaust.
12.2
When the IMSI Administrator informs the CSCN, CRTC staff, Industry Canada
and the ITU Study Group 2 Chair that the MCC 302 assigned to Canada is
approaching exhaust, the IMSI Administrator will:
a)
b)
c)
Conduct an audit of current IMSI assignment reports to determine if IMSI
utilization is efficient and, if necessary,
Provide the requisite data to CRTC staff and the ITU Study Group 2 Chair
so that Industry Canada may request additional MCC resources from the
ITU-T.
Currently, MCCs 303-307 are not allocated. Should additional MCCs be
required by Canada, MCCs in this list of unallocated MCCs could be
requested in order to continue with consecutive MCC allocations.
13.0 Maintenance of Guidelines
It may be necessary to modify this Guideline periodically to meet changing and
unforeseen circumstances. The need for Guideline modification may be identified by the
administrator, the CRTC or any entity in the telecommunications sector. The CSCN will
