Abstract
A method and devices may assist in addressing signaling efficiency issues when the network aims to page a group of UEs in a multicast group so that the UEs will switch from CM-IDLE state to CM-CONNECTED state.
Claims16
A wireless transmit/receive unit (WTRU) comprising:
- a processor;
- and
- a memory coupled with the processor, the memory comprising executable instructions stored thereon that when executed by the processor cause the WTRU to effectuate operations comprising:
- join a multicast session of a network, wherein the multicast session is associated with a first group identifier (ID) of a multicast group that includes the WTRU;
- when connected with the multicast session, enter into a connection management (CM) idle state;
- receive a paging message from the network, the paging message comprising a second group identifier (ID) that is associated with the multicast session;
- determine that the paging message is associated with the multicast group based on the second group ID being a hashed version of the first group ID that was determined by hashing the first group ID with an ID of the WTRU;
- and
- send, based on the paging message, a service request to the network.
