A method includes receiving a request to initiate an emergency call, directing, the mobile device to initiate the emergency call using a cellular network, receiving a network not available indication that the emergency call cannot be completed using the cellular network, selecting location information of the mobile device and requesting the emergency call be initiated by a VoIP client on the mobile device using the location information obtained from the selecting step.

E-911 redirection system and method

Aspects of the subject disclosure may include, for example, a method, including applying a voice quality model to network performance information associated with a voice over internet protocol call session to generate a measure of voice quality associated with a first wireless radio access network wirelessly coupling a mobile device and a communication network, detecting a trigger condition for a measurement reporting according to the measure of voice quality, a first signal of the first wireless radio access network, and a second signal of a second wireless radio access network, and detecting a trigger condition for a measurement report according to the measure of voice quality, a first signal of the first network, and a second signal of a network. The measurement report can be transmitted to the first wireless radio access network responsive to detecting the trigger condition for the measurement reporting. Other embodiments are disclosed.

Method and system for managing wireless connectivity in a communication system

Aspects of the subject disclosure may include, for example, a method, including applying a voice quality model to network performance information associated with a voice over internet protocol call session to generate a measure of voice quality associated with a first wireless radio access network wirelessly coupling a mobile device and a communication network, detecting a trigger condition for a measurement reporting according to the measure of voice quality, a first signal of the first wireless radio access network, and a second signal of a second wireless radio access network, and detecting a trigger condition for a measurement report according to the measure of voice quality, a first signal of the first wireless radio access network, and a second signal of a second wireless radio access network. The measurement report can be transmitted to the first wireless radio access network responsive to detecting the trigger condition for the measurement reporting. The first wireless radio access network can transmit a handover request to the second wireless radio access network based on applying a first handover policy to the measure of voice quality, the first signal, and the second signal of the measurement report. The second wireless radio access network can initiate a second wireless coupling of the mobile device and the communication network to complete a handover of the voice over internet protocol call session to the second wireless radio access network responsive to a handover request from the first wireless radio access network. Other embodiments are disclosed.
