Automatic transfer of mobile calls between voice over internet protocol (VoIP) and guaranteed service (GS) networks based on quality of service (QoS) measurements

摘要

Methods, systems, and computer readable media for the automatic transfer of mobile calls between wireless packet switched (PS) and guaranteed service (GS) networks based on quality of service (QoS) measurements are disclosed. One method includes establishing a call over the PS or GS network. The method may further include monitoring a quality of service (QoS) parameter associated with the PS network, and comparing the QoS parameter to a minimum quality threshold. The method may further include receiving instructions to initiate a call transfer based upon the comparison of the QoS parameter to the minimum quality threshold.

1. A service node configured to automatically transfer a mobile call between a packet switched (PS) network and a guaranteed service (GS) network, the service node comprising:
a processor; and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the service node to:
facilitate establishment of a call between a first mobile device and a second mobile device via the GS network;receive an instruction from a mobile client executed by the first mobile device to start a connectivity check;in response to the instruction, measure a quality of service (QoS) parameter of a connection between the first mobile device and the service node via the PS network;report the measured QoS parameter to the mobile client; andinitiate an operation to transfer the call from the GS network to the PS network in response to an indication from the mobile client that the measured QoS parameter meets or exceeds a minimum quality threshold.
