Title: SYSTEM AND METHODS FOR INCREASING A MAXIMUM NUMBER OF SIMULTANEOUS CALLS ON A SERVICE SUBSCRIPTION OF A MULTI-SIM DEVICE
Abstract:
Methods and devices are disclosed for increasing capacity for handling simultaneous calls to a particular SIM of a wireless communication device having at least a first and second SIM and corresponding first and second radio resources. If a preset maximum number of calls has been reached for a first of the modem stacks, and a radio resource of another other modem stack is handling less than its preset maximum number of calls, the wireless device may send a signal to the network serving the first SIM to activate the call forwarding function. While activated, calls addressed to the first SIM may be received by the wireless device on radio resource associated with the other SIM.
