Abstract
A method and apparatus for transmitting an interest indication for group communication in a wireless communication system is provided. A user equipment (UE) receives a paging message indicating a group, establishes a radio resource control (RRC) connection with an establishment cause indicating the group, and transmits an uplink interest indication message which informs a service or the group.
Claims8
A method for transmitting, by a user equipment (UE), an interest indication for group communication in a wireless communication system, the method comprising:
- receiving a paging message, which includes a group communication service enabler (GCSE) identity (ID), indicating a GCSE group;
- establishing a radio resource control (RRC) connection with an establishment cause indicating the GCSE group;
- and
- transmitting an uplink interest indication message including the interest indication which informs the GCSE group entitled to participate in the group communication, upon establishing the RRC connection,
- wherein the uplink interest indication message is transmitted to one of an eNodeB (eNB), a mobility management entity (MME) or a GCSE server, and
- wherein the uplink interest indication message is a multimedia broadcast multicast service (MBMS) interest indication message.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a radio frequency (RF) transceiver configured to transmit or receive a radio signal;
- and
- a processor coupled to the RF transceiver, and configured to:
- receive a paging message, which includes a group communication service enabler (GCSE) identity (ID), indicating a GCSE group,
- establish a radio resource control (RRC) connection with an establishment cause indicating the GCSE group, and
- transmit an uplink interest indication message including the interest indication which informs the GCSE group entitled to participate in a group communication, upon establishing the RRC connection,
- wherein the uplink interest indication message is transmitted to one of an eNodeB (eNB), a mobility management entity (MME) or a GCSE server, and
- wherein the uplink interest indication message is a multimedia broadcast multicast service (MBMS) interest indication message.
