METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR PATH SWITCH IN DEVICE-TO-DEVICE COMMUNICATION

摘要

Methods, corresponding apparatuses, and computer program products for path switch in the D2D communication are provided. The method comprises receiving, from a network element, a path switch command which is generated when a pair of user equipments in device-to-device communication over a default data path is served by the same base station. The method further comprises switching, based at least in part upon the path switch command, a data path of the pair of user equipments in the device-to-device communication from the default data path to an optimized data path. With the claimed inventions, smooth switching could be realized without degradation to the user experience.
