Abstract
A method and apparatus for keeping track of User equipment (UE) locations without regard to an existing Radio Resource Controller (RRC) connection for multicast services in a Routing Area Network (RAN). The invention includes performing a multicast area update procedure in the RRC whether the UE has an existing RRC connection or not. The performing step includes sending from the UE a MULTICAST AREA UPDATE message when the UE detects whether a multicast area change has occurred.
Claims18
A method of keeping track of User equipment (UE) locations without regard to an existing Radio Resource Controller (RRC) connection for multicast services in a Routing Area Network (RAN), comprising the steps of:
- performing a multicast area update procedure in the RRC whether the UE has an existing RRC connection or not,
- wherein said performing step comprises:
- sending from the UE a MULTICAST AREA UPDATE message when the UE detects whether a multicast area change has occurred.
A method of keeping track of User equipment (UE) locations without regard to an existing Radio Resource Controller (RRC) connection for multicast services in a Routing Area Network (RAN), comprising the steps of:
- performing a multicast area update procedure in the RRC when the UE has an existing RRC connection,
- wherein said performing step comprises:
- sending from the UE a MULTICAST AREA UPDATE message when the UE detects whether a multicast area change has occurred.
A radio network controller (RNC) in a wireless communications network, said radio network controller carrying out a method of keeping track of User Equipment (UE) locations without regard to an existing Radio Resource Controller (RRC) connection for multicast services in a Routing Area Network (RAN), comprising the steps of:
- performing a multicast area update procedure in the RRC whether the UE has an existing RRC connection or not,
- wherein said performing step comprises:
- receiving from the UE a MULTICAST AREA UPDATE message when the UE detects whether a multicast area change has occurred.
