1. A user equipment device (UE), comprising:
at least one antenna;
at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one cellular radio access technology (RAT); and
one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform voice and/or data communications;
wherein the one or more processors are configured to cause the UE to:
determine, at the UE, that a first paging occasion for a first 3GPP network overlaps with a second paging occasion of a second 3GPP network, wherein the overlap causes the UE to miss at least one page on one of the first or second 3GPP networks, wherein the UE is registered to the first 3GPP network and the second 3GPP network; and
in response to determining that the first paging occasion overlaps with the second paging occasion, perform at least one collision avoidance procedure that results in a timing of the second paging occasion being adjusted relative to the first paging occasion, thereby allowing the UE to receive pages on both the first and second 3GPP networks, wherein the at least one collision avoidance procedure includes the UE transmission of a non-access stratum (NAS) request message to adjust the timing of the second paging occasion relative to the first paging occasion.
 
9. An apparatus, comprising:
a memory; and
at least one processor in communication with the memory;
wherein the at least one processor is configured to:
determine that a first paging occasion for a first 3GPP network overlaps with a second paging occasion of a second 3GPP network, wherein the overlap causes at least one page on one of the first or second 3GPP networks to be missed; and
in response to determining that the first paging occasion overlaps with the second paging occasion, perform at least one collision avoidance procedure that results in a timing of the second paging occasion being adjusted relative to the first paging occasion, thereby allowing the UE to receive pages on both the first and second 3GPP networks, wherein the at least one collision avoidance procedure includes the UE transmitting a non-access stratum (NAS) request message to adjust the timing of the second paging occasion relative to the first paging occasion.
 
17. A non-transitory computer readable memory medium storing program instructions executable by processing circuitry to cause a user equipment device (UE) to:
determine that a first paging occasion for a first 3GPP network overlaps with a second paging occasion of a second 3GPP network, wherein the overlap causes the UE to miss at least one page on one of the first or second 3GPP networks, wherein the UE is registered to the first 3GPP network and the second 3GPP network; and
in response to determining that the first paging occasion overlaps with the second paging occasion, perform at least one collision avoidance procedure that results in a timing of the second paging occasion being adjusted relative to the first paging occasion, thereby allowing the UE to receive pages on both the first and second 3GPP networks, wherein the at least one collision avoidance procedure includes the UE transmitting a non-access stratum (NAS) request message to adjust the timing of the second paging occasion relative to the first paging occasion.
