Abstract

A first base station receives a handover request. The handover request indicates for each packet flow of packet flows of a wireless device: whether the packet flow is for at least one V2X service; and a quality-of-service indicator of the packet flow. A determination is made whether to accept each packet flow of the packet flows based on whether the packet flow is for the at least one V2X service. The first base station sends an indication of an acceptance or rejection of each packet flow of the packet flows.

First claim

The invention claimed is:

1. A method comprising:
receiving, by a first base station, a handover request indicating for each packet flow of packet flows of a wireless device:
whether the packet flow is for at least one vehicle-to-everything (V2X) service; and
a quality-of-service indicator of the packet flow;

determining whether to accept each packet flow of the packet flows based on whether the packet flow is for the at least one V2X service; 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 comprises configuration parameters associated with the at least one V2X service for the wireless device.

3. The method of claim 2 , further comprising transmitting, by a second base station to the wireless device, a handover command comprising the configuration parameters, wherein the sending the indication comprises sending the indication by the first base station to the second base station.

4. The method of claim 1 , further comprising receiving, by a second base station, a message indicating whether the packet flow is for the at least one V2X service, wherein:
the receiving the message comprises receiving the message from at least one of:
a core network entity; or
a third base station; and

the receiving the handover request comprises receiving the handover request by the first base station from the second base station.

5. The method of claim 1 , further comprising determining, by the first base station, whether to accept the handover request for the wireless device based on whether the packet flow is for the at least one V2X service.

6. The method of claim 1 , wherein the handover request indicates whether the packet flow is for at least one of:
a vehicle-to-vehicle (V2V) service;
a vehicle-to-network (V2N) services;
a vehicle-to-pedestrian (V2P) services; or
a vehicle-to-infrastructure (V2I) services.

7. The method of claim 1 , wherein the handover request indicates whether the packet flow is for at least one of:
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.

8. The method of claim 1 , wherein the handover request indicates a temporary mobile group identity (TMGI) associated with the packet flow.

9. The method of claim 1 , wherein the handover request indicates a periodic resource scheduling requirement for the packet flow.

10. The method of claim 1 , further comprising transmitting, by the first base station to the wireless device, packets via the packet flow.

11. A first base station comprising:
one or more processors;
memory storing instructions that, when executed by the one or more processors, cause the first base station to:
receive a handover request indicating for each packet flow of packet flows of a wireless device:
whether the packet flow is for at least one vehicle-to-everything (V2X) service; and
a quality-of-service indicator of the packet flow;

determine whether to accept each packet flow of the packet flows based on whether the packet flow is for the at least one V2X service; and
send an indication of an acceptance or rejection of each packet flow of the packet flows.

12. The first base station of claim 11 , wherein the indication comprises configuration parameters associated with the at least one V2X service for the wireless device.

13. The first base station of claim 12 , wherein:
a second base station sends, to the wireless device, a handover command comprising the configuration parameters; and
the sending the indication comprises sending the indication to the second base station.

14. The first base station of claim 11 , wherein:
a second base station receives the indication of whether the packet flow is for the at least one V2X service from at least one of:
a core network entity; or
a third base station; and

the receiving the handover request comprises receiving the handover request by the first base station from the second base station.

15. The first base station of claim 11 , wherein the instructions, when executed, further cause the first base station to determine whether to accept the handover request for the wireless device based on whether the packet flow is for the at least one V2X service.

16. The first base station of claim 11 , wherein the handover request indicates whether the packet flow is for at least one of:
a vehicle-to-vehicle (V2V) service;
a vehicle-to-network (V2N) services;
a vehicle-to-pedestrian (V2P) services; or
a vehicle-to-infrastructure (V2I) services.

17. The first base station of claim 11 , wherein the handover request indicates whether the packet flow is for at least one of:
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.

18. The first base station of claim 11 , wherein the handover request indicates a temporary mobile group identity (TMGI) associated with the packet flow.

19. The first base station of claim 11 , wherein the handover request indicates a periodic resource scheduling requirement for the packet flow.

20. The first base station of claim 11 , wherein the instructions, when executed, further cause the first base station to transmit, to the wireless device, packets via the packet flow.
