Methods and apparatus for using device to device communications to support IMS based services

摘要

A method, an apparatus, and a computer program product for wireless communication are provided in connection with using D2D communications to support at least a portion of IMS based services. In one example, a first UE is equipped to perform communications with a second UE using an IMS session in which data traffic and signaling traffic are supported through a network, determine that the second UE is within a first proximity threshold of the first UE, establish a D2D communication link with the second UE, and transfer support of the data traffic to the D2D communication link while maintaining the support of the signaling traffic through the network. In an aspect, the first proximity threshold may be a distance, a signaling strength or a signaling quality between the first and second UEs between which D2D communications are supported.
