Embodiment Construction

[0025] Referring first to FIG. 1 , there is shown a communication network 100 comprising a packet switched communication system 104 and circuit switched networks 112 and 120 . In one embodiment, packet-switched communication system 104 may be a peer-to-peer system operating on a packet-switched network, such as the Internet. Circuit switched networks 112 and 120 may be PSTN (Public Switched Telephone Network) networks.

[0026] User equipment 102 is shown connected to peer-to-peer system 104 via session node 106 . User equipment 102 is also connected to PSTN network 120 . In one embodiment of the invention, the user equipment is connected to the PSTN network 112 via the circuit switched connection 222 and to the session node 106 via the packet switched connection 111 . Circuit switched connection 222 and packet switched connection 111 may be provided by a GSM (Global System for Mobile communications) network (not shown). For example a packet switched connection may be provi...

Abstract

A method of controlling a communication session between a user of a communication network and a communication system wherein the communication network comprises a first network and a second network, and wherein the communication system operates on the first network said method comprising; transmitting a session request packet from a device associated with the user to a first node located in the first network; initiating the session for the user with the communication system at the first node in response to receiving the session request, wherein during the session the method comprises the steps of; providing from the first node to the device a calling identity for use by the device during a communication event between the user and an entity via the communication system, wherein the calling identity may be used to establish a connection between the device and a second node located in the second network determining an address of the entity; and associating the calling identity with the address of the entity; wherein upon termination of the session the calling identity is disassociated from the address of the entity.

Description

technical field [0001] The invention relates to a method for handling communications in a communications system. Background technique [0002] A communication system links communication devices together so that the devices can send information to each other during a call or other communication event. The information may include voice, text, images or video. [0003] One such communication system is a peer-to-peer communication system in which a plurality of end users can connect for communication purposes via a communication structure such as the Internet using peer-to-peer client software. The communication structure is substantially decentralized with regard to the communication routes in which the exchange takes place in order to connect the end users. That is, end users are able to establish their own communication routes through the structure to gain access to the structure based on the exchange of one or more authorization credentials (User Identity Certificate - UIC...
