Method for call control in intelligent networks

Abstract

The presentation of information identifying a calling user of a terminal device (MS-A) to a called terminal device (MS-B) in a communication involving a radio access network is triggered upon receipt of an incoming call; if triggered, the information is presented to a user at a man machine interface (MMI) of the terminal device; a user input is collected via the man machine interface (MMI) in response to the presentation, and the received call is controlled according to the collected user input. It becomes advantageously possible to initiate a retrieval procedure for calling party identifying information while the call is being controlled by a service control device and prior to the routing of the call to the called terminal device.

1 . A method for call control by a called terminal device receiving a call via a communication network for intelligent network services, said network comprising 
 a service control device and a server device communicating with each other via an interface,    said service control device being connected to at least one service switching device establishing communication via at least one radio access network with said terminal device, and    said terminal device being provided with a browser adapted to communicate with a user of said terminal device via a man machine interface, and adapted to communicate with said server device,    the method comprising:    receiving an incoming call at said service switching device,    triggering a presentation service at said service control device;    if triggered, retrieving information identifying a calling user of a terminal device from an external server;    providing said information identifying said calling user of a terminal device to said called terminal device;    presenting said information identifying said calling user of a terminal device at the browser of said man machine interface of said terminal device;    collecting a user input via said man machine interface in response to said presentation,    providing information on said collected user input to said service control device, and    controlling said received call by said service control device according to said collected user input.
