摘要： A method for optimising the distribution of data objects between caches in a cache domain of a resource limited network. User requests for data objects are received at caches in the cache domain. A notification is sent from each cache at which a request received to a cache manager. The notification reports the user request and identifies the requested data object. At the cache manager, object information including the request frequency of each requested data object and the locations of the caches at which the requests were received are collated and stored, and objects for distribution within the cache domain are identified on the basis of the object information. Instructions are sent from the cache manager to the caches to distribute data objects stored in those caches between themselves. The data objects are distributed between the caches using transmission capacity of the network that would otherwise be unused.

摘要： The invention relates to a method and entity that allow for saving of uplink bandwidth in connection with peer-to-peer sharing in a wireless communication system. A caching entity, called a reverse cache, intercepts a point-to-point connection between a mobile network user plane gateway and a wireless user equipment running a peer-to-peer application. The reverse cache caches content loaded to the peer-to-peer application and stores information indicative of the wireless user equipment to which the cached content is loaded. A request on the point-to-point connection for delivery of a first content from the wireless user equipment is intercepted by the reverse cache. When the requested first content is cached in the reverse cache along with information indicating that the requested first content has been loaded to the wireless user equipment, the reverse cache responds by delivering the requested first content, without involving the wireless user equipment.

摘要： A method and apparatus for sending user plane traffic via a node located between a base station and a Serving Gateway in a mobile telecommunications network. The base station receives a message containing tunneling protocol information identifying the Serving Gateway. It sends a second message towards the node, the second message including tunneling protocol information identifying the base station and the Serving Gateway. The base station receives a third message from the node, the third message including tunneling protocol information for the base station to use towards the node, and tunneling protocol information for the Serving Gateway to use towards the node. A fourth message is sent, which includes tunneling protocol information for the Serving Gateway to use towards the node. User plane traffic can then be sent between the base station and the Serving Gateway via the node.

摘要： A method of providing for the transfer of an IP flow when a client is handed over from a first to a second radio layer node of a cellular communications network. The method comprises establishing said IP flow between a client and an application of a local service network within or connected to said first radio layer node, and sending said IP flow over a radio access bearer extending between the client and the first radio layer node, and maintaining within a mobility database a mapping between an identifier of the client, an IP address of said application, and an IP address of said local service network. Prior to or upon handover of the client from said first radio layer node to the second radio layer node, a request including the client identifier is sent from said second to said first radio layer node or to another node if the central mobility database is maintained in that other node. The client identifier contained in said request is used at said first radio layer node or said other node to identify said mapping in the mobility database, and the application and local service network IP addresses are sent from said first radio layer node or said other node, to said second radio layer node. The application and local service network IP addresses are received at said second radio layer node, and the received local service network IP address are used at said second radio layer node to establish a tunnel between the second radio layer node and said local service network. Said IP flow is switched from said radio access bearer to said tunnel for delivery to the client via said second radio layer node.

摘要： Method and radio network controller of a mobile telecommunication network for providing DNS redirection in a mobile telecommunication network. The radio network controller includes an interface configured to receive a DNS query from a mobile terminal and a domain name system, DNS, interceptor module. The DNS interceptor module is configured to intercept the DNS query from the mobile terminal, detect the indication of the content originator server or the content delivery provider, check the indication against a list of domain names handled by the radio network controller, and generate a DNS reply in response to the DNS query, the DNS reply including an IP address of a content server associated with the radio network controller and not including an IP address of the content delivery provider. The interface is configured to send the DNS reply to the mobile terminal.

摘要： A method and apparatus for handing over a terminal connection. A handover request is sent from a source base station to a target base station. A first control message is also sent from the source base station to a control server, the first control message including a session identifier for identifying the session, and current parameters for the session. If the target base station is associated with a cache storage unit containing the content data, a second control message is sent from the control server to the target base station, the second control message including a content identifier, the session identifier and the current parameters. At the target base station, the content data packets are retrieved from the cache storage unit, and a header of each retrieved content data packet is populated with parameters calculated using the received current parameters and session identifier. The content data packets are then sent from the base station towards the terminal.

摘要： A method for setting up a VPN is described. The VPN is set up in a backbone network having a plurality of PE routers for controlling the transfer of IP traffic to and from CE routers in satellite networks. In a PE router, a VRF is configured for the VPN and populated with local routes for the VPN. A VRF IP loopback address is assigned for the VRF, and a PE IP loopback address is assigned for the ingress PE router. A local route with the VRF and PE IP loopback addresses is then advertised to other PE routers in the backbone network.
