Responding to second base station addition request for vehicle-to-everything (V2X)
A first base station receives a second base station addition request indicating, for each packet flow of packet flows of a wireless device, whether each packet flow is for at least one vehicle-to-everything (V2X) service, and a quality-of-service indicator of each packet flow. The first base station sends an indication of an acceptance or rejection of each packet flow of the packet flows.
1 . A method comprising:
receiving, by a first base station, a handover request message indicating, for each packet flow of packet flows of a wireless device:
whether each packet flow is for at least one vehicle-to-everything (V2X) service; and
a quality-of-service indicator of each packet flow; and
sending, by the first base station, an indication of an acceptance or rejection of each packet flow of the packet flows.
2 . The method of claim 1 , wherein the indication of the acceptance or rejection is based on the handover request message indicating whether each packet flow is for the at least one V2X service.
3 . The method of claim 1 , wherein the handover request message comprises a secondary base station addition request for a dual connectivity of the wireless device.
4 . The method of claim 3 , wherein the wireless device receives a configuration message for the dual connectivity from a second base station; and wherein:
the indication is sent by the first base station to the second base station; and
the configuration message is based on the indication.
5 . The method of claim 1 , wherein the handover request message indicates whether each packet flow is for at least one of:
a vehicle-to-vehicle (V2V) service;
a vehicle-to-network (V2N) service;
a vehicle-to-pedestrian (V2P) service;
a vehicle-to-infrastructure (V2I) service;
a multimedia broadcast multicast service single frequency network (MBSFN) service;
a single cell point to multipoint (SC-PTM) service; or
a sidelink-based V2X service.
6 . The method of claim 1 , wherein the handover request message indicates at least one of:
a temporary mobile group identity (TMGI) associated with each packet flow; or
a periodic resource scheduling requirement for each packet flow.
7 . The method of claim 1 , wherein:
a second base station receives, from a core network entity or a third base station, a message indicating whether each packet flow is for the at least one V2X service; and
the receiving the handover request message comprises receiving a second base station addition request by the first base station from the second base station.
8 . A first base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the first base station to:
receive a handover request message indicating, for each packet flow of packet flows of a wireless device:
whether each packet flow is for at least one vehicle-to-everything (V2X) service; and
a quality-of-service indicator of each packet flow; and
send an indication of an acceptance or rejection of each packet flow of the packet flows.
9 . The first base station of claim 8 , wherein the handover request message comprises a secondary base station addition request for a dual connectivity of the wireless device.
10 . The first base station of claim 9 , wherein the wireless device receives, from a second base station, a configuration message for the dual connectivity; and wherein:
the indication is sent by the first base station to the second base station; and
the configuration message is based on the indication.
11 . The first base station of claim 8 , wherein the indication comprises configuration parameters associated with the at least one V2X service for the wireless device.
12 . The first base station of claim 8 , wherein the instructions, when executed, further cause the first base station to determine whether to accept the handover request message for the wireless device based on whether each packet flow is for the at least one V2X service.
13 . The first base station of claim 8 , wherein the handover request message indicates whether each packet flow is for at least one of:
a vehicle-to-vehicle (V2V) service;
a vehicle-to-network (V2N) service;
a vehicle-to-pedestrian (V2P) service;
a vehicle-to-infrastructure (V2I) service;
a multimedia broadcast multicast service single frequency network (MBSFN) service;
a single cell point to multipoint (SC-PTM) service; or
a sidelink-based V2X service.
14 . The first base station of claim 8 , wherein the handover request message indicates at least one of:
a temporary mobile group identity (TMGI) associated with each packet flow; or
a periodic resource scheduling requirement for each packet flow.
15 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a first base station, cause the first base station to:
receive a handover request message indicating, for each packet flow of packet flows of a wireless device:
whether each packet flow is for at least one vehicle-to-everything (V2X) service; and
a quality-of-service indicator of each packet flow; and
send an indication of an acceptance or rejection of each packet flow of the packet flows.
16 . The non-transitory computer-readable medium of claim 15 , wherein the indication indicates the acceptance or rejection of each packet flow, of the packet flows, for the at least one V2X service.
17 . The non-transitory computer-readable medium of claim 15 , wherein the indication comprises configuration parameters associated with the at least one V2X service for the wireless device.
18 . The non-transitory computer-readable medium of claim 15 , wherein the handover request message indicates whether each packet flow is for at least one of:
a vehicle-to-vehicle (V2V) service;
a vehicle-to-network (V2N) service;
a vehicle-to-pedestrian (V2P) service;
a vehicle-to-infrastructure (V2I) service;
a multimedia broadcast multicast service single frequency network (MBSFN) service;
a single cell point to multipoint (SC-PTM) service; or
a sidelink-based V2X service.
19 . The non-transitory computer-readable medium of claim 15 , wherein the handover request message indicates at least one of:
a temporary mobile group identity (TMGI) associated with each packet flow; or
a periodic resource scheduling requirement for each packet flow.
20 . The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the first base station to transmit, to the wireless device, packets via each packet flow.
