METHOD FOR ENABLING LAWFUL INTERCEPTION IN A TELECOMMUNICATIONS NETWORK USER EQUIPMENT FOR ENABLING LAWFUL INTERCEPTION IN A TELECOMMUNICATIONS NETWORK BASE TRANSCEIVER STATION FOR ENABLING LAWFUL INTERCEPTION IN A TELECOMMUNICATIONS NETWORK PROGRAM AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for enabling lawful interception in a telecommunications network the telecommunications network comprising a core network and an access network wherein a user equipment camping on the telecommunications network is enabled for device to device communication wherein the access network of the telecommunications network comprises a base transceiver station wherein the user equipment is connected to the base transceiver station and the base transceiver station is enabled for allowing the user equipment to conduct device to device communication wherein in case that the user equipment is subjected to a lawful interception observation and the user equipment is sending a request to the base transceiver station to conduct a device to device communication a first message is sent from the base transceiver station to the user equipment wherein the first message comprises the indication of a permission to conduct a device to device communication by the user equipment wherein either the first message or a second message sent from the base transceiver station to the user equipment furthermore comprises a transmission power information wherein the transmission power information is indicative of a minimum transmission power of the user equipment when conducting device to device communication.
