Communication coordination and collision mitigation for multi-subscriber identity module devices
This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.
1. An apparatus, comprising:
a processor configured to cause a wireless device to:
determine a first network associated with a first subscriber identity module (SIM);
determine a second network associated with a second SIM;
determine information for a coordination request to avoid a collision between a first communication from the first network for the first SIM and a second communication from the second network for the second SIM, wherein the information includes an offset limit to a paging occasion of the first SIM indicated by the first network to the wireless device;
transmit, to a base station associated with the first network, the coordination request to avoid the collision, wherein the coordination request includes a requested offset to the paging occasion of the first SIM, wherein the requested offset is less than the offset limit; and
communicate, with the base station, according to the coordination request, wherein said communicating avoids the collision.
2. The apparatus of claim 1 , wherein the coordination request includes a request to the first network to alter a paging occasion of the first SIM.
3. The apparatus of claim 2 , wherein the first network and the second network are different.
4. The apparatus of claim 2 , wherein the first network and the second network are different, wherein the coordination request includes an indication to the first network of a paging occasion of the second SIM.
5. The apparatus of claim 1 , wherein the first network and the second network are the same, wherein the coordination request includes an indication to the first network to transmit pages for the first SIM on a paging occasion associated with the second SIM.
6. The apparatus of claim 1 , wherein the first network and the second network are different, wherein the coordination request includes an indication regarding how or if the first network should transmit alert system messages to the wireless device.
7. The apparatus of claim 6 , wherein the first network is a home network for the first SIM and the second network is a home network for the second SIM, wherein the second SIM is a data preferred SIM, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
8. The apparatus of claim 6 , wherein the second network is a home network for the second SIM and the first network is a roaming network for the first SIM, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
9. The apparatus of claim 6 , wherein the first SIM and the second SIM are both camped on a same cell with a different mobile country code (MCC) and/or a mobile network code (MNC), wherein the processor is further configured to cause the wireless device to select the second SIM based on the MCC and/or MNC, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
10. A wireless device, comprising:
a radio; and
a processor operably coupled to the radio and configured to cause the wireless device to:
determine a first network associated with a first subscriber identity module (SIM);
determine a second network associated with a second SIM;
determine information for a coordination request to avoid a collision between a first communication from the first network for the first SIM and a second communication from the second network for the second SIM, wherein the information includes an offset limit to a paging occasion of the first SIM indicated by the first network to the wireless device;
transmit, to a base station associated with the first network, the coordination request to avoid the collision, wherein the coordination request includes a requested offset to the paging occasion of the first SIM, wherein the requested offset is less than the offset limit; and
communicate, with the base station, according to the coordination request, wherein said communicating avoids the collision.
11. The wireless device of claim 10 , wherein the coordination request includes a request to the first network to alter a paging occasion of the first SIM.
12. The wireless device of claim 11 , wherein the first network and the second network are different.
13. The wireless device of claim 11 , wherein the first network and the second network are different, wherein the coordination request includes an indication to the first network of a paging occasion of the second SIM.
14. The wireless device of claim 10 , wherein the first network and the second network are the same, wherein the coordination request includes an indication to the first network to transmit pages for the first SIM on a paging occasion associated with the second SIM.
15. The wireless device of claim 10 , wherein the first network and the second network are different, wherein the coordination request includes an indication regarding how or if the first network should transmit alert system messages to the wireless device.
16. The wireless device of claim 15 , wherein the first network is a home network for the first SIM and the second network is a home network for the second SIM, wherein the second SIM is a data preferred SIM, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
17. The wireless device of claim 15 , wherein the second network is a home network for the second SIM and the first network is a roaming network for the first SIM, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
18. The wireless device of claim 15 , wherein the first SIM and the second SIM are both camped on a same cell with a different mobile country code (MCC) and/or a mobile network code (MNC), wherein the processor is further configured to cause the wireless device to select the second SIM based on the MCC and/or MNC, wherein the indication indicates that the wireless device will retrieve alert system messages over the second network.
19. A method, comprising:
at a wireless device:
determining a first network associated with a first subscriber identity module (SIM);
determining a second network associated with a second SIM;
determining information for a coordination request to avoid a collision between a first communication from the first network for the first SIM and a second communication from the second network for the second SIM, wherein the information includes an offset limit to a paging occasion of the first SIM indicated by the first network to the wireless device;
transmitting, to a base station associated with the first network, the coordination request to avoid the collision, wherein the coordination request includes a requested offset to the paging occasion of the first SIM, wherein the requested offset is less than the offset limit; and
communicating, with the base station, according to the coordination request, wherein said communicating avoids the collision.
20. The method of claim 19 , wherein the coordination request includes a request to the first network to alter a paging occasion of the first SIM.
