ROUTING PAGING MESSAGES FOR MULTIPLE SUBSCRIPTION IDENTITIES OF A SINGLE COMMUNICATION DEVICE VIA A SINGLE PAGING CHANNEL

摘要

A method is provided for conserving power on a wireless communication device having multi-subscription capabilities. Instead of scanning different paging channels for each of a plurality of subscriptions, power may be conserved by using a single paging channel from a serving access network for all paging messages from the plurality of subscriptions. The wireless communication device may provide a serving access network information for the plurality of subscriptions, where each of the plurality of subscriptions is associated with a different paging channel. The serving access network may select or obtain a single paging channel for all paging messages from different core networks associated with the plurality of subscriptions. The wireless communication device may be informed of the selected paging channel by the access network so it monitors for paging messages for all subscriptions on that selected paging channel only.

1. A method operational on a wireless communication device, comprising:
registering with at least one of a serving access network or a first core network while providing information for a plurality of subscriptions, including the first subscription, of the wireless communication device, where each of the plurality of subscriptions is associated with a different paging channel; receiving an indication that a first paging channel associated with one of the plurality of subscriptions has been selected for all paging messages for the plurality of subscriptions; and monitoring the first paging channel for paging messages for the plurality of subscriptions.
