2. Issues regarding UIE

Binding issues
Separation of goals and means, Deciding where binding occurs,
Interoperability and compatibility, Ownership of space and
authentication of entities

Quality of Service (QoS) issues
Conflict resolution: priority and scheduling, Criteria of QoS,
Service level agreement, Mobility

Scalability issues
Service Delivery, Scalability of Data and Process

Security and Privacy issues
Scalable mutual authentication, ownership and usage of users’
record and preference

3. Inter-space Interactions

Resolving issues of Inter-space Interaction
• Binding Issues: Cross-layered concept
• QoS Issues: Virtual personal space concept
• Scalability Issues: Service Gene concept

4. Wrapping Up


UIE: Inevitable prerequisite features for future
computer and communication industry
Approach of Resolving issues on Inter-space
Interaction
• Cross-layered concept for binding issues
• Virtual personal space concept for QoS issues
• Service gene concept for scalability issues
