Intercepting device-to-device communication

摘要

Mobile network (MN) for mobile devices (UE1, UE2), the mobile devices being arranged for exchanging communication data via the mobile network or, by selection, via a Device-To-Device [D2D] communication channel, the mobile network comprising a base station (ENB1) and a controller (010), wherein the controller (010) is arranged for: i) receiving an interception request from a lawful intercept controller (020), the interception request being indicative of a subscriber; ii) determining whether a target device associated with the subscriber participates in the D2D communication channel (D2D) based on D2D control data; and iii) if the target device is deemed to participate in the D2D communication channel (D2D), requesting the base station (ENB1) to intercept the communication data exchanged via the D2D communication channel (D2D); and wherein the base station (ENB1) is arranged for, in response to a request from the controller, intercepting radio signals (RS) of the D2D communication channel based on the D2D control data.

主权项

1. A mobile network for mobile devices, the mobile devices being arranged for exchanging communication data via the mobile network or, by selection, via a Device-To-Device (D2D) communication channel, the mobile network comprising:
a base station for establishing a control channel between one of the mobile devices and the mobile network; and a controller for, via the control channel, i) receiving a request from said one of the mobile devices for establishing the D2D communication channel with a further mobile device, and ii) controlling the establishing of the D2D communication channel by exchanging D2D control data with said one of the mobile devices; wherein the controller is arranged for: i) receiving an interception request from a lawful intercept controller, the interception request being indicative of a subscriber; ii) determining whether a target device associated with the subscriber participates in the D2D communication channel based on the D2D control data; iii) if the target device is deemed to participate in the D2D communication channel, requesting the base station to intercept the communication data exchanged via the D2D communication channel; and wherein the base station is arranged for, in response to a request from the controller, intercepting radio signals of the D2D communication channel based on the D2D control data.
