Techniques for managing sessions in multiple-subscription wireless communications
Aspects described herein relate to requesting suspending of a data session of a first when a device capable of communicating over multiple subscriptions switches from an active communication state if the first network to an active communication state in a second network. The device can also request resuming the data session based on switching back to active communication state with the first network.

transmitting, to the first network and based on determining to transition to the active communication state on the second subscription, a suspend request to suspend a data session;
receiving paging signals from the first network in communication gaps configured in the second network for determining whether to transition back to an active communication state on the first network; and
transmitting, to the first network, a resume request to resume the data session based on receiving the paging signals based on determining to transition back to an active communication state on the first network.
2. The method of claim 1 , wherein receiving the at least one signal from the second network comprises receiving at least one paging signal from the second network.
3. The method of claim 1 , further comprising generating the suspend request to include a session identifier for the data session.

5. The method of claim 1 , further comprising generating the resume request to include a session identifier for the data session.
6. The method of claim 1 , further comprising transitioning to the active communication state on the second subscription.
7. The method of claim 6 , further comprising receiving a response to the suspend request to suspend the data session, wherein the response confirms suspending of the data session with the first network, and wherein transitioning to the active communication state on the second subscription is based at least in part on receiving the response.
8. The method of claim 1 , wherein transmitting the suspend request to suspend the data session comprises transmitting the suspend request to a mobility management entity (MME) in long term evolution (LTE) or an access and mobility management function (AMF) in new radio (NR).
9. The method of claim 1 , wherein transmitting the resume request comprises transmitting the resume request to a mobility management entity (MME) in long term evolution (LTE) or an access and mobility management function (AMF) in new radio (NR).

determine, based on receiving the at least one signal from the second network, to transition to an active communication state on the second subscription;
transmit, to the first network and based on determining to transition to the active communication state on the second subscription, a suspend request to suspend a data session;
receive paging signals from the first network in communication gaps configured in the second network for determining whether to transition back to an active communication state on the first network; and
transmit, to the first network, a resume request to resume the data session based on receiving the paging signals based on determining to transition back to an active communication state on the first network.
11. The apparatus of claim 10 , wherein the one or more processors are configured to receive at least one paging signal from the second network.
12. The apparatus of claim 10 , wherein the one or more processors are further configured to generate the suspend request to include a session identifier for the data session.
13. The apparatus of claim 10 , wherein the one or more processors are further configured to transition to an idle state in the second subscription, wherein the one or more processors are configured to transmit the resume request based at least in part on transitioning to the idle state.
14. The apparatus of claim 10 , wherein the one or more processors are further configured to generate the resume request to include a session identifier for the data session.
15. The apparatus of claim 10 , wherein the one or more processors are further configured to transition to the active communication state on the second subscription.
16. The apparatus of claim 15 wherein the one or more processors are further configured to receive a response to the suspend request to suspend the data session, wherein the response confirms suspending of the data session with the first network, and wherein the one or more processors are configured to transition to the active communication state on the second subscription is based at least in part on receiving the response.
17. The apparatus of claim 10 , wherein the one or more processors are configured to transmit the suspend request to a mobility management entity (MME) in long term evolution (LTE) or an access and mobility management function (AMF) in new radio (NR).
18. The apparatus of claim 10 , wherein the one or more processors are configured to transmit the resume request to a mobility management entity (MME) in long term evolution (LTE) or an access and mobility management function (AMF) in new radio (NR).
