Method for activating recordings of events concerning terminals and equipment therefor

A radio network controller in a radiocommunication system designed to implement an activation of recordings of events concerning radio terminals, the radiocommunication system also including a core network and an operation center suitable for supervising the radio network controller, the radio network controller being connected to the core network and including means for controlling radio communications with terminals and also including:

• means for receiving from the operation center a coded list of terminal identifiers;
• means for transmitting the coded list of terminal identifiers to the core network;
• and
• means for receiving, from the core network, and applying an instruction to start a recording of events concerning a call with a terminal identified from the coded list of terminal identifiers, said call having been detected in the core network.

A core network of a radiocommunication system designed to implement an activation of recording of events concerning radio terminals, the radiocommunication system also including at least one radio network controller connected to the core network and designed to control radio communications with radio terminals and at least one operation center suitable for supervising said radio network controller, the core network including:

• means for receiving, from the radio network controller, a coded list of terminal identifiers;
• means for decoding the coded list;
• means for detecting a call under the control of the radio network controller, with a terminal identified from the decoded list;
• and
• means for instructing the radio network controller to start a recording of events concerning the detected call.

A radiocommunication system including a core network, at least one radio network controller connected to the core network and designed to control radio communications with terminals and at least one operation center suitable for supervising said radio network controller, the radiocommunication system comprising:

• means for transmitting, from the operation center to a radio network controller, a coded list of terminal identifiers;
• means for transmitting the coded list of terminal identifiers to the core network from the radio network controller;
• means for decoding the coded list of terminal identifiers at the core network;
• means for detecting, at the core network, a radio communication under the control of the radio network controller, with a terminal identified from the decoded list;
• and
• means for instructing the radio network controller, from the core network, to start a recording of events relating to the detected call.
