MULTIPLE SIM MULTIPLE NETWORK DIVERSITY FOR ENHANCING CALL CONNECTIVITY

摘要

Methods and devices are disclosed for establishing a second call during a first call on a multi-SIM communication device. A quality of the first call between a calling party and a called party using a first subscription for a first network may be determined to be degrading. Network alternatives may be provided for establishing the second call in response to determining that the quality of the first call is degrading. One of the network alternatives may be selected based on an order of suitability for originating the second call. A notification to the called party using information associated with calling party and the second call may be provided before the second call is originated. The information associated with the second call may identify the calling party to the called party before the second call is originated.
