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 |
20090049159 | Method and Apparatus for Setting Up and Managing Operational Environment in P2P Wireless Networks - In a cognitive radio, a method of establishing an operational policy for use in a Peer-to-Peer (P2P) group, wherein the policy can be described by layers of policy parameters with progressively higher layers having a progressively increasing number of parameters, involves determining that a policy change is to be made from a current policy; requesting policy information from at least one P2P group member; receiving a policy description from the at least one P2P group member; and implementing a change in the lowest layer policy parameter to establish a new operational policy. | 02-19-2009 |

20100056184 | PRESENCE-AWARE CELLULAR COMMUNICATION SYSTEM AND METHOD - A cellular communication system comprises a network supporting user equipment over an air interface, the network having a hierarchical cell arrangement with overlay cells and underlay cells. An underlay base station is associated with a subset of registered user equipment. An activation server switches the underlay base station between an inactive mode and an active mode in response to detecting that registered user equipment meets a location criterion. The underlay base station only supports user equipment when in the active mode, e.g., it may only transmit a pilot signal in this mode. Interference and power consumption may be substantially reduced by sending the base station into the inactive mode thereby resulting in increased capacity of the cellular communication system as a whole. | 03-04-2010 |
20100167732 | PROVIDING OVER-THE-TOP SERVICES ON FEMTO CELLS OF AN IP EDGE CONVERGENCE SERVER SYSTEM - A method is provided for enabling an over the top (OTT) service over a broadband network. The method includes receiving a registration request from a mobile User Equipment (UE) over a femto cell to register with a cellular operator of a cellular network. The registration request is forwarded to an authentication, authorization, and accounting (AAA) server associated with the cellular operator to register the mobile UE therewith. A rendition of the registration request is forwarded to an AAA server associated with a broadband operator of a broadband network to register the mobile UE therewith. | 07-01-2010 |
20100167740 | WIDE AREA MOBILE COMMUNICATIONS OVER FEMTO-CELLS - A method and apparatus is provided for hand-off of a mobile User Equipment (UE) across a femto cellular network. The method includes dynamically clustering a plurality of neighboring femto cells in a vicinity of a first femto cell to which a mobile UE is currently attached. The dynamic cluster of neighboring femto cells is moved across the femto cellular network in accordance with movement of the mobile UE across the femto cellular network. | 07-01-2010 |
20140181160 | SEQUENTIAL SEMANTIC REPRESENTATIONS FOR MEDIA CURATION - Generating a sequential semantic representation and a resulting content item sequence or presentation is disclosed. A set of nodes and paths among the nodes are determined. Each node includes a corresponding a set of criteria. The paths define a relationship among the plurality of nodes. Transitional operators that define additional criteria for the nodes, are associated with the paths. Content items that include characteristics that are determined to match the corresponding set of criteria for at least one of the nodes are retrieved. | 06-26-2014 |
