Introductions
• EMBS_Zone_ID is used to identify an unique EMBS
Zone
• Neighbor ABSs’ E-MBS zone affiliations that can
facilitate inter-MBS zone transition are carried in AAIE-MBS_CFG or in AAI_NBR-ADV
• However, idle AMSs will miss both messages because
idle AMSs do not interpret A-A-MAP
– Current E-MBS design does not consider the interests of idle
AMSs
• In order to facilitate inter-MBS zone transition for idle
AMSs, neighbor ABSs’ E-MBS zone affiliations shall
be advertised at a pre-determined location
AAI_E-MBS-ADV transmission
• In this proposal, neighbor ABSs’ E-MBS zone affiliations
are included in the cell-specific E-MBS configuration
message, AAI_E-MBS-ADV
– AAI_E-MBS-ADV is transmitted in the next DL sub-frame following
E-MBS region
– AMSs in connected state and idle state can receive AAI_E-MBS-ADV
• AAI_E-MBS-ADV may be transmitted periodically or
when needed
• A cell-specific configuration indicator is included in EMBS
MAP to notify AMSs the presence of AAI_E-MBS-ADV
message

15.9.3.2 E-MBS Zone Configuration
When the E-MBS Zone identifier list appears in AAI_NBR_ADV message with only
one value of '0' for some of ABS's, it indicates that the corresponding neighbor
ABSs are not affiliated with any E-MBS zone.
The ABS sends AAI_DSA for establishment of connection for E-MBS, E-MBS
ZONE shall be encoded in the AAI-DSA message. One ABS may have multiple EMBS Zone IDs for different E-MBS services.
To support inter-MBS zone transition, AMSs need to get E-MBS_Zone_IDs to
which the neighboring ABS’s belong as well as any flow continuity across such
neighboring zone. E-MBS configuration information that facilitates continuous
reception of E-MBS data or seamless inter-MBS zone transition is carried in
AAI_E-MBS-ADV message. AAI_E-MBS-ADV may be transmitted periodically or
when it is needed. The cell-specific configuration indicator shall be set to 0b1 if
AAI_E-MBS-ADV is transmitted, otherwise it shall be set to 0b0. If AAI_E-MBSADV is transmitted, the Assignment A-MAP in the next DL subframe following the
E-MBS region shall indicate the allocation of AAI_E-MBS-ADV message. The
content of AAI_E-MBS-ADV message may include the cell-specific configuration
information such as MBS zone identifiers of serving BS, MBS zone identifiers of
neighboring BSs.
