1 21-05-xxxx-00-0000 IEEE 802.21 MEDIA INDEPENDENT HANDOVER DCN: 21-06-xxxx-00-0000 Title: Support for query of the registered event at MIH Layer and Link Layer Presented at IEEE 802.21 session #17 in Dallas Authors or Source(s): Dong Peiying, Shu Guiming, Guo Junxiang Abstract: For the convenience of the implement of the MIH, the query methods for the registered events should be provided. Through the methods, MIH User can query its registered events from MIH Function and MIH Function can query its registered events from Lower link layers.

3 21-05-xxxx-00-0000 Background In current draft, we have MIH_Event_Register.request and Link_Event_Register.request for MIH Users and MIHF to register events they concerned at MIH Layer and Link Layer, and by the primitives of MIH_Event_Register.confirm and Link_Event_Register.confirm, MIH Users and MIHF can know what events have been registered successfully. In general, there are more than one MIH Users will register events they concerned at MIH Function, for the reason of this, every MIH User has to remember their registered event status for future use, such as in some time it wants a different list of events indication, it can compare the new list to the old list then go to next step. So if there is query method of the registered event between MIH User and MIH Function, it will be much easier for the implement of the MIH User, for it can query the registered event status at any time. While there is also query requirement of registered event between MIH Function and Link Layer.

4 21-05-xxxx-00-0000 Background Now that we have methods for registering events, for convenience we should have some methods for query event registered at different layers. Through the methods, MIH Users and MIHF can query what events they have registered at target layers.

5 21-05-xxxx-00-0000 New primitives for query of the registered events Add new primitives for query of registered events at MIHF : …… 7.4.15 MIH_RegisteredEvent_Discover 7.4.15.1 MIH_RegisteredEvent_Discover.request 7.4.15.1.1 Function This primitive is used by MIH User (the registrant) to query what events it has registered at MIH Function. The response indicates the events list which the MIH User has registered at MIH Function. 7.4.15.1.2 Semantics of the service primitive The parameters of the primitive are as follows: MIH_RegisteredEvent_Discover.request ( SourceIdentifier, DestinationIdentifier, LinkIdentifier)

6 21-05-xxxx-00-0000 New primitives for query of the registered events NameTypeValid rangeDescription Source IdentifierIdentifierAny valid individual or group identifier The identifier of entity where the request is initiated. This field may be optionally left empty if the command is local. Destination Identifier IdentifierValid MIHF identifier The destination identifier of request or response. This is the identifier of local or peer MIHF. 7.4.15.1.3 When generated This primitive is generated by a registrant such as MIH User that is seeking to query what events it has registered at MIHF. 7.4.15.1.4 Effect on receipt The recipient responds immediately with MIH_Event_Register.confirm primitive.

7 21-05-xxxx-00-0000 New primitives for query of the registered events 7.4.15.1 MIH_RegisteredEvent_Discover.confirm 7.4.15.1.1 Function This primitive return the results of the request of the query of registered event by MIH User. 7.4.15.1.2 Semantics of the service primitive The parameters of the primitive are as follows: MIH_RegisteredEvent_Discover.confirm ( SourceIdentifier, DestinationIdentifier, LinkIdentifier RegisteredEventList )

8 21-05-xxxx-00-0000 New primitives for query of the registered events NameTypeValid rangeDescription RegisteredEventList Set of Event IDs Set of valid link events The list of the registered events. 7.4.15.1.3 When generated This primitive is generated in response to a MIH_RegisteredEvent_Discover.request primitive. 7.4.15.1.4 Effect on receipt The recipient may examine the returned event list and learn about the registration status of different events.

9 21-05-xxxx-00-0000 New primitives for query of the registered events Add new primitives for query of registered events at Link Layer : …… 7.3.22 Link_RegisteredEvent_Discover.request 7.3.22.1 Function This primitive is used by MIH Function (the registrant) to query what events it has registered at Lower Layer. The response indicates the events list which the MIH Function has registered at Lower Layer. 7.3.22.2 Semantics of the service primitive The parameters of the primitive are as follows: Link_RegisteredEvent_Discover.request ( )

10 21-05-xxxx-00-0000 New primitives for query of the registered events 7.3.22.3 When generated This primitive is generated by a registrant such as MIH Function that is seeking to query what events it has registered at Lower Layer. 7.3.22.4 Effect on receipt The recipient responds immediately with Link_RegisteredEvent_Discover.request primitive. 7.3.23 Link_RegisteredEvent_Discover.confirm 7.3.23.1 Function This primitive return the results of the request of the query of registered event by MIH Function. 7.3.23.2 Semantics of the service primitive The parameters of the primitive are as follows: Link_RegisteredEvent_Discover.confirm ( RegisteredEventList )

11 21-05-xxxx-00-0000 New primitives for query of the registered events NameTypeValid rangeDescription RegisteredEventList Set of Event IDs Set of valid link events The list of the registered events of link layer. 7. 3.23.3 When generated This primitive is generated in response to a Link_RegisteredEvent_Discover.request primitive. 7. 3.23.4 Effect on receipt The recipient may examine the returned event list and learn about the registration status of different events.
