METHODS AND APPARATUS TO REUSE WIRELESS CIRCUITRY FOR MULTIPLE SUBSCRIBER IDENTITIES IN A WIRELESS COMMUNICATION DEVICE

摘要

Apparatus and methods to reuse wireless circuitry to communicate with multiple wireless networks to support multiple subscriber identities in a wireless communication device are disclosed. A representative method includes receiving signaling messages for a second subscriber identity from a second wireless network while connected to a first wireless network for a first subscriber identity. A portion of radio frequency wireless circuitry is reconfigured to communicate with the second wireless network to establish a signaling channel and respond to signaling messages received from the second wireless network. The portion of radio frequency wireless circuitry is reconfigured between the first and second wireless networks to maintain a connection with the first wireless network while also receiving from the second wireless network limited information that can be provided to a user. Representative information includes an indication of an originator of a mobile terminated connection request and short message service data.

主权项

1. A method to reuse wireless circuitry for communication by a wireless communication device to a second wireless network while connected to a first wireless network, the method comprising:
by the wireless communication device:
when connected to the first wireless network via a first wireless cellular protocol software stack for a first subscriber identity associated with a first subscriber identity module:
receiving a paging request for a second subscriber identity associated with a second subscriber identity module from a second wireless network;reconfiguring a portion of the wireless circuitry of the wireless communication device to communicate with the second wireless network via a second wireless cellular protocol software stack;establishing a signaling channel with the second wireless network after reconfiguring the portion of the wireless circuitry;sending a paging response to the second wireless network in response to the paging request via the signaling channel;receiving information associated with the paging request from the second wireless network via the signaling channel;releasing the signaling channel with the second wireless network after receiving the information associated with the paging request; andreconfiguring the portion of the wireless circuitry to communicate with the first wireless network via the first wireless cellular protocol software stack after releasing the signaling channel.
