Abstract

Technology for a lawful interception of a proximity service (e.g., device-to-device (D2D) communication) provided to user equipments (UEs) is disclosed. In an example, a method can include an evolved Node B (eNB) transmitting a proximity service setup message to a first UE to setup D2D communication with a second UE. The eNB can transmit a lawful interception message to the first UE or the second UE to provide lawful interception of the D2D communication. The eNB can receive packets associated with the D2D communication from the first UE or the second UE. The eNB can communicate the received packets from the first UE and the second UE to the core network (CN) to be copied.
