Claim Text:
1. A method for a lawful interception of a proximity service provided to user equipments (UEs), comprising: transmitting a proximity service setup message from an evolved Node B (eNB) to a first UE to setup device-to-device (D2D) communication with a second UE; transmitting a lawful interception message from the eNB to the first UE or the second UE to provide lawful interception of the D2D communication; receiving packets associated with the D2D communication from the first UE or the second UE; communicating the received packets from the first UE and the second UE to a core network (CN) to be copied; instructing the first UE or the second UE to generate an artificial D2D link between the first UE and the second UE, wherein the D2D communication appears to the either the first UE or to the second UE to use the artificial D2D link and the artificial D2D link provides status signaling, wherein communication between the first UE and the second UE passes through the eNB; and communicating a message to the CN to disable charges for communication associated with the artificial D2D link passing through the eNB even when charges for direct communication with the eNB apply.
