Methods and systems disclosed herein can help to dynamically adjust page transmission power, and in particular, the transmission power for quick paging bits, depending upon whether a user equipment (UE) is operating as a single radio LTE (SRLTE) device. An exemplary method involves an access network making a determination that a UE is configured to use a single radio system for (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol; and responsively initiating a process to set a transmission power used to page the first UE for a voice call under the second air interface protocol to a higher power level, as compared to a transmission power level utilized to page a second UE configured to use separate radio systems for data communication under the first air interface protocol and voice calls under the second air interface protocol.

The method of claim 3, wherein, to operate as an SRLTE device, the first UE is configured to: periodically switch from a connected state to a disconnected state under the first air interface protocol; andwhen disconnected under the first air interface protocol, monitor a paging channel defined under the second air interface protocol for a page message indicating an incoming voice call for the first UE. 5. The method of claim 4, wherein the paging channel defined under the second air interface protocol is a quick paging channel (QPCH) defined under a code division multiple access protocol. 6. The method of claim 1, wherein making the determination that the first UE is configured to use a single radio system for both data communication under the first air interface protocol and voice calls under the second air interface protocol comprises: initially receiving, from another network entity, a message indicating that the UE is configured to use a single radio system for both data communication under the first air interface protocol and voice calls under the second air interface protocol. 7. The method of claim 1, wherein making the determination that the first UE is configured to use a single radio system for both data communication under the first air interface protocol and voice calls under the second air interface protocol comprises: initially receiving, by the network entity, a message from the UE indicating the UE is configured to use a single radio system for both data communication under the first air interface protocol and voice calls under the second air interface protocol. 8. The method of claim 7, wherein the received message comprises a registration message that registers the UE with the radio access network under the second air interface protocol. 9. The method of claim 7, wherein the received message comprises a registration message that registers the UE in a particular paging zone from a plurality of paging zones. 10. The method of claim 1, wherein the network entity comprises a base station, and wherein initiating the process to set the transmission power used to page the first UE for a voice call under the second air interface protocol to the higher power level comprises: the base station sending, to a switch, the message indicating that the first UE is configured as an SRLTE device, such that the switch updates a paging table entry for the first UE to indicate the first UE is configured as an SRLTE device. 11. The method of claim 1, wherein pages to the first UE under the second air interface protocol are sent via a quick paging channel (QPCH), wherein a paging table initially indicates a default transmission power for the first UE on the QPCH, and wherein initiating the process to set the transmission power used to page the first UE for a voice call under the second air interface protocol to a higher value comprises initiating a process to update the paging table to indicate a higher transmission power for the first UE on the QPCH. 12. The method of claim 11, wherein the default transmission power is three decibels (dB) below a transmission power for a pilot channel, and wherein the higher transmission power is one dB below the transmission power for the pilot channel. 13. A system comprising: a communication interface operable for communications under a first air interface protocol;a non-transitory computer readable medium; andprogram instructions stored on the non-transitory computer readable medium and executable by at least one processor to: (i) make a determination that a first user equipment (UE) is configured to use a single radio system for both (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol that is different from the first air interface protocol; and(ii) in response to making the determination, initiate a process to set a transmission power used to page the first UE for a voice call under the second air interface protocol to a higher power level, as compared to a transmission power level utilized to page a second UE configured to use separate radio systems for data communication under the first air interface protocol and voice calls under the second air interface protocolwherein initiation of the process comprises sending a message indicating that the first UE is configured as a Single Radio Long-Term Evolution (SRLTE) device, so as to cause an update to a paging table entry for the first UE to indicate that the first UE is configured as an SRLTE device. 14.
