Abstract

Wireless communications for network access configuration are described. A base station may configure a monitoring gap for a wireless device, based on information received from the wireless device. The wireless device may use the monitoring gap to communicate with another base station associated with another wireless network.

First claim

The invention claimed is:

1. A method comprising:
sending, by a wireless device to a first base station associated with a first network, a first message indicating assistance information for communicating with a second base station associated with a second network;
receiving, from the first base station and based on the first message, a second message indicating a communication gap for communicating with the second base station; and
communicating, during the communication gap, with the second base station.

2. The method of claim 1 , wherein the assistance information comprises at least one of:
an indication of periodicity of paging indications;
an indication that the wireless device communicates with the first network;
an indication that the assistance information is to monitor the first network;
an identifier of the first network; or
discontinuous reception (DRX) configuration parameters, associated with the wireless device, at the first base station.

3. The method of claim 1 , wherein the wireless device is in a radio resource control (RRC) connected state with the second base station during the communication gap.

4. The method of claim 1 , wherein the second message indicates at least one of:
a gap periodicity;
a gap time offset; or
a gap size.

5. The method of claim 1 , wherein the first message comprises an indication of at least one of:
a timing offset of paging indications; or
a size of the paging indications.

6. The method of claim 1 , wherein the first message comprises at least one of:
a field indicating that the first message is for a vehicle-to-everything service via the first network;
a field indicating that the first message is for an emergency service via the first network;
a field indicating that the first message is for an ultra-reliable low-latency communication service via the first network;
a field indicating a priority of a service; or
a field indicating that the first message is for a primary network associated with the wireless device.

7. The method of claim 1 , wherein the wireless device comprises a dual subscriber identity module (SIM) device.

8. The method of claim 1 , wherein the first network comprises a first public land mobile network (PLMN), and wherein the second network comprises a second PLMN.

9. The method of claim 1 , wherein the communicating with the second base station comprises at least one of:
a registration area update procedure;
a tracking area update procedure;
a radio access network (RAN) area update procedure;
an early data transmission;
transmission or reception of a paging indication; or
transmission or reception of transport blocks for at least one service.

10. The method of claim 1 , wherein the second message comprises an activation indication of a power saving mode, and wherein the method further comprises:
activating the power saving mode for the first network.

11. The method of claim 1 , wherein the second message indicates a repetition period and a time offset that are associated with the communication gap for communicating with the second base station.

12. 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:
send, to a first base station associated with a first network, a first message indicating assistance information for communicating with a second base station associated with a second network;
receive, from the first base station and based on the first message, a second message indicating a communication gap for communicating with the second base station; and
communicate, during the communication gap, with the second base station.

13. The wireless device of claim 12 , wherein the assistance information comprises at least one of:
an indication of periodicity of paging indications;
an indication that the wireless device communicates with the first network;
an indication that the assistance information is to monitor the first network;
an identifier of the first network; or
discontinuous reception (DRX) configuration parameters, associated with the wireless device, at the first base station.

14. The wireless device of claim 12 , wherein the wireless device is in a radio resource control (RRC) connected state with the second base station during the communication gap.

15. The wireless device of claim 12 , wherein the second message indicates at least one of:
a gap periodicity;
a gap time offset; or
a gap size.

16. The wireless device of claim 12 , wherein the first message comprises an indication of at least one of:
a timing offset of paging indications; or
a size of the paging indications.

17. The wireless device of claim 12 , wherein the first message comprises at least one of:
a field indicating that the first message is for a vehicle-to-everything service via the first network;
a field indicating that the first message is for an emergency service via the first network;
a field indicating that the first message is for an ultra-reliable low-latency communication service via the first network;
a field indicating a priority of a service; or
a field indicating that the first message is for a primary network associated with the wireless device.

18. The wireless device of claim 12 , wherein the wireless device comprises a dual subscriber identity module (SIM) device.

19. The wireless device of claim 12 , wherein the first network comprises a first public land mobile network (PLMN), and wherein the second network comprises a second PLMN.

20. The wireless device of claim 12 , wherein the instructions, when executed by the one or more processors, cause the wireless device to communicate with the second base station by performing at least one of:
a registration area update procedure;
a tracking area update procedure;
a radio access network (RAN) area update procedure;
an early data transmission;
transmission or reception of a paging indication; or
transmission or reception of transport blocks for at least one service.

21. The wireless device of claim 12 , wherein the second message comprises an activation indication of a power saving mode.

22. The wireless device of claim 12 , wherein the second message indicates a repetition period and a time offset that are associated with the communication gap for communicating with the second base station.

23. A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
send, to a first base station associated with a first network, a first message indicating assistance information for communicating with a second base station associated with a second network;
receive, from the first base station and based on the first message, a second message indicating a communication gap for communicating with the second base station; and
communicate, during the communication gap, with the second base station.

24. The non-transitory computer-readable medium of claim 23 , wherein the assistance information comprises at least one of:
an indication of periodicity of paging indications;
an indication that the wireless device communicates with the first network;
an indication that the assistance information is to monitor the first network;
an identifier of the first network; or
discontinuous reception (DRX) configuration parameters, associated with the wireless device, at the first base station.
