| 20080235185 | COMMUNICATION SYSTEM AND METHOD OF ACCESSING THEREFOR - A communication system comprises a user equipment which may access a network via an access network element. Initially, the user equipment transmits a query message to a default network entry point which then contacts a home registration server for the user equipment. The home registration server determines an access network element determination server associated with a current location of the user equipment. The user equipment is informed of the access network element determination server and contacts this. In response, the access network element determination server determines a list of access network elements for the user equipment and transmits the list to the user equipment. The user equipment then registers for a communication service by accessing the network using a selected access network element selected from the list of access network elements. The invention may be particular suitable for accessing an IP Multimedia Subsystem (IMS) via a Customer Premises Equipment (CPE). | 09-25-2008 |
| 20080235778 | COMMUNICATION NETWORK, AN ACCESS NETWORK ELEMENT AND A METHOD OF OPERATION THEREFOR - An access network element provides user equipment access to a network comprising a centralised authentication server. The access network element comprises an authentication processor which authenticates the access network element at the centralised authentication server. In addition, the access network element authenticates a first user equipment in response to the authentication of the access network element by the centralised authentication server. A communication processor supports a peer-to-peer first communication session for the first user equipment and a peer-to-peer second communication session with a second access network element which supports a peer-to-peer communication session with a second user equipment. Peer-to-peer communication between the first and second user equipments is supported by exchanging data between the first communication session and the second communication session. The invention may allow benefits of de-centralised peer-to-peer communications to be combined with existing centralised network architectures such as the Internet Protocol Multimedia Subsystem, IMS. | 09-25-2008 |
