Abstract
Systems, methods, apparatuses, and computer program products for changing MRB ID without requiring release and add functions. One method may include receiving, by a user equipment, a RRC reconfiguration message from a network entity comprising a MRB. The MRB is identified by a first MRB ID, and the RRC reconfiguration message further comprises a second MRB ID associated with the first MRB ID. The user equipment associates the MRB with the second MRB ID configured for subsequent identification of the MRB. The user equipment receives MBS data through the MRB associated with the second MRB ID.
Claims19
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- receive a radio resource control reconfiguration message from a network entity comprising a multicast and broadcast radio bearer wherein the multicast and broadcast radio bearer is identified by a first multicast and broadcast service radio bearer identifier and the radio resource control reconfiguration message further comprising a second multicast and broadcast service radio bearer identifier associated with the first multicast and broadcast service radio bearer identifier;
- associate the multicast and broadcast radio bearer with the second multicast and broadcast service radio bearer identifier configured for subsequent identification of the multicast and broadcast radio bearer;
- and
- receive multicast and broadcast service data through the multicast and broadcast radio bearer associated with the second multicast and broadcast service radio bearer identifier.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- receive a handover request from a source network entity, wherein the handover request comprises a first multicast and broadcast service radio bearer identifier and a list comprising at least one quality of service flow identifier associated with the first multicast and broadcast service radio bearer identifier;
- and
- transmit, within a handover request acknowledgement, a multicast and broadcast service radio bearer configuration to a user equipment comprising the first multicast and broadcast service radio bearer identifier and a second multicast and broadcast service radio bearer identifier associated with the first multicast and broadcast service radio bearer identifier.
A method, comprising:
- receiving a radio resource control reconfiguration message from a network entity comprising a multicast and broadcast radio bearer wherein the multicast and broadcast radio bearer is identified by a first multicast and broadcast service radio bearer identifier and the radio resource control reconfiguration message further comprising a second multicast and broadcast service radio bearer identifier associated with the first multicast and broadcast service radio bearer identifier;
- associating the multicast and broadcast radio bearer with the second multicast and broadcast service radio bearer identifier configured for subsequent identification of the multicast and broadcast radio bearer;
- and
- receiving multicast and broadcast service data through the multicast and broadcast radio bearer associated with the second multicast and broadcast service radio bearer identifier.
