摘要:
A method of facilitating path switching, for a communication path between a first user equipment (UE) and a second UE, from a device to device (D2D) path to network path, includes receiving switch point information from the first UE that identifies a data block; establishing, at the access network, a connection with the first UE over an uplink path between the first UE and the access network; establishing, at the access network, a connection with the second UE over a downlink path between the network element and the second UE; setting, at the access network, a data block sequencing numbering to be the same for the uplink path and the downlink path based on the switch point information; and forwarding, at the access network, data from the first UE to the second UE via the network path, the network path including the uplink path and the downlink path.
