Method and system for paging a multi-mode mobile station

摘要

A multi-mode mobile station is able to communicate with a first system using a first air interface protocol (e.g., EVDO) and with a second system using a second air interface protocol (e.g., 1×RTT CDMA). When the first system schedules a page message for transmission to the multi-mode mobile station, the first system may query the second system to determine whether the second air interface protocol is being used for a current call involving the multi-mode mobile station or is being used to attempt establishment of a requested call to the multi-mode mobile station. In the case of a current call, the first system may wait until the call is released before transmitting the page message. In the case of an attempt to establish a requested call, the first system may wait to determine whether the attempt is successful before transmitting the page message.

主权项

1. A method for a radio access network (RAN) serving a multi-mode mobile station, wherein said multi-mode mobile station is able to communicate using a first air interface protocol and a second air interface protocol, said method comprising:
said RAN selecting, based on a slot cycle index of said multi-mode mobile station, a first time slot for transmission of a communication to said multi-mode mobile station using said first air interface protocol; and after selecting said first time slot, said RAN making a determination that said second air interface protocol is being used for a current call involving said multi-mode mobile station or is being used to attempt establishment of a requested call to said multi-mode mobile station; after making said determination, said RAN determining a disposition of said current or requested call; after determining said disposition of said current or requested call, said RAN selecting a second time slot; and said RAN transmitting said communication in said second time slot to said multi-mode mobile station using said first air interface protocol.
