Handover of Wireless Device
A non-transitory computer-readable medium comprises instructions that, when executed by one or more processors, cause the one or more processors to: receive, from a wireless device, one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast service (MBS) services that the wireless device is receiving or interested to receive; send, to a second base station, a message requesting a handover of the wireless device and comprising the one or more TMGIs; receive, from the second base station, an acknowledge message comprising a group-radio network temporary identifier (G-RNTI) associated with at least one of the one or more MBS services; and transmit, to the wireless device, a radio resource control message comprising the G-RNTI.

an MBS service priority; or
a V2X service priority.
8 . The non-transitory computer-readable medium of claim 1 , wherein the instructions further cause the first base station to receive, from the wireless device, a measurement report, wherein the sending the message is in response to the measurement report.
9 . The non-transitory computer-readable medium of claim 1 , wherein the message is sent to the second base station via a core network device.
10 . The non-transitory computer-readable medium of claim 1 , wherein the sending the message comprises sending the message to a plurality of second base stations, comprising the second base station.
11 . A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
transmit, to a first base station, a temporary mobile group identifier (TMGI) of a multimedia broadcast service (MBS) that the wireless device is receiving or interested to receive;
receive, from the first base station, a handover command message comprising a group-radio network temporary identifier (G-RNTI) of a second base station and associated with the MBS; and
receive, from the second base station and based on the G-RNTI, a packet associated with the MBS.
12 . The wireless device of claim 11 , wherein the handover command message comprises MBS configuration parameters of the MBS.
13 . The wireless device of claim 12 , wherein the MBS configuration parameters comprise at least one of:
the TMGI; or
an MBS session identifier.
14 . The wireless device of claim 12 , wherein the MBS configuration parameters comprise at least one of:
single cell multicast traffic channel (SC-MTCH) scheduling parameters comprising at least one of:
an on-duration timer single cell point to multipoint (SCPTM);
a discontinuous reception (DRX) inactivity timer SCPTM;
a scheduling period start offset SCPTM; or
a cell identifier of an SC-MTCH neighbor cell providing the at least one of the one or more MBS services on SC-MTCH.
15 . The wireless device of claim 12 , wherein the MBS configuration parameters comprise at least one of:
a radio frame allocation period;
a radio frame allocation offset; or
one or more subframe allocation parameters.
16 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:
transmit, to a first base station, a temporary mobile group identifier (TMGI) of a multimedia broadcast service (MBS) that the wireless device is receiving or interested to receive;
receive, from the first base station, a handover command message comprising a group-radio network temporary identifier (G-RNTI) of a second base station and associated with the MBS; and
receive, from the second base station and based on the G-RNTI, a packet associated with the MBS.
17 . The non-transitory computer-readable medium of claim 16 , wherein the handover command message comprises MBS configuration parameters of the MBS.
