Abstract: An access network connection controller is disclosed for ordering a mobile terminal to switch from a connection to a first access network to a connection to a second access network in order to ensure that a good connection to the mobile terminal is maintained when the mobile terminal enters an area in which connection to the first access network may be restricted and the second access network may be beneficial. The access network connection controller is operable to receive movement information representative of the movement of the mobile terminal connected to a first access network; to determine from the movement information whether the mobile terminal is approaching a restricted area wherein connection to a second access network may be beneficial and to generate a command ordering the switching of the connection mobile terminal from the first access network to the second access network before the mobile terminal enters the restricted area.

Abstract: A PUE in communication with an ANDSF server through an access network includes a network interface unit of the PUE from which a registration request is sent to the ANDSF server through the access network and which receives a successful authentication result and a set of configuration instructions from the ANDSF server. The PUE includes a processing unit of the PUE which determines one or more observation triggers from the set of configuration instructions. Upon fulfillment of the observation trigger, the processing unit activates one or more interfaces supported by the PUE, which the set of configuration instructions requires to be monitored. The processing unit determines consolidated areas, wherein each consolidated area includes those geographical points with given network characteristics for one or more accessible networks. The consolidated areas data are stored in the memory and submitted by the network interface unit to the ANDSF server through the access network.

Abstract: Methods and apparatus are disclosed for controlling and distributing data traffic among neighboring access networks within a geographic area. Subscribers may be given different priorities. Requests of services by subscribers may be prioritized. Data traffic within a congested access network may be offloaded to alternate access networks based on criteria such as service types and Quality of Service requirements associated with the data traffic, subscriber priorities associated with the subscribers, software and hardware capabilities associated with the user terminals of the subscribers, and resource availabilities in the alternate access networks.

Abstract: A method and apparatus for stored message delivery are taught. The method and apparatus can be configured to accomplish the steps of receiving a Session Initiation Protocol (SIP) message, as a received SIP message, encapsulating the received SIP message in a Message Session Relay Protocol (MSRP) message, as an encapsulated SIP message; and transmitting the encapsulated SIP message to an intended recipient.

Abstract: A method provides callback services in a communications system to a first party from a second party. The method includes supplying the second party with a telephone number of the first party in a first format. The method also includes selecting a numbering plan out of plurality of numbering plans based on at least one of the country and network where the second party is located. The method also includes converting the telephone number from the first format to a second format using the selected numbering plan.

Abstract: A method of setting up a session between peer user terminals of a communication system, wherein at least one of the user terminals is a dual-mode terminal having access to both an IP-based packet-switched access network and a circuit-switched access network, and the session extends at least in part across the circuit-switched access network. One of the user terminals initiates the session by sending Session Initiation Protocol (SIP) signaling to a SIP server over the IP-based network. The SIP server sends a notification to a gateway server to establish one or more conversational bearers. The gateway server then sends a callback telephone number to the dual-mode terminal. The dual-mode terminal then calls the callback number to establish a circuit-switched session with the gateway server.

Abstract: The invention relates to a method for the routing of multimedia communication related signaling in a communication system. In the method a signaling message is received to a first network node. The signaling message provides an identity associated with a user. A hash key is computed from the identity. The hash key is matched to a number of key ranges, each key range being associated with a network node. A second network node is determined by detecting that said hash key belongs to the key range of the second network node. A signaling message is provided to the second network node. Subscriber data associated with the identity is obtained in from the second network node. The signaling message is processed in the second network node based on information in the subscriber data.

Abstract: A method of enabling a terminal 1,2 coupled to a GSTN 10 to join an Internet based presence service facilitated by a presence server 6. The method comprises establishing a telephone connection between said terminal 1,2 and an intermediate server 4 via the GSTN 10, as a result of said connection, establishing a proxy entity corresponding to said terminal 1,2 at said intermediate server 4 and registering the proxy entity with the presence server 6 via the Internet, and exchanging presence service messages between the presence server 6 and the proxy entity at the intermediate server 4 via the Internet and between the proxy entity and said terminal 1,2 via the GSTN network 10.

Abstract: The technology described relates to telecommunication networks and more specifically to a method and an arrangement for signalling in a wireless IP multimedia network and to a wireless IP multimedia network terminal device and permits 3GPP Core Network IP Multimedia Subsystems and all associated products including mobile terminals, Media Gateway, Media Gateway Control Function, etc. to support DTMF tones.

Abstract: A node and method are provided that create a finger table at the node, subscribe to changes in a network address of at least one other node included in the finger table, receive at least one notification including an identifier and a network address of the at least one other node, and update the finger table with a new network address of the at least one other node received in the at least one notification. The node and method also create a reverse finger table at a node, receive subscriptions to changes in a network address of the node from another node, store the network address of the other node in the reverse finger table, and when the network address of the node changes, send a notification of a new network address from the node to the other node in the reverse finger table.

Abstract: A method of delivering a copy of a Session Initiation Protocol, SIP, message to each of a plurality of terminals in a multimedia communication system. The method comprises receiving the message at a first SIP exploder, grouping destination addresses defined for the SIP message according to their network domains, and for each group of destination addresses corresponding to a domain associated with a further SIP exploder, forwarding a single copy of the message to that exploder, the message containing all of the destination addresses of the group.

Abstract: A method of setting up a call between first and second nodes of a communication system when the call extends across a circuit switched access network and a packet switched backbone network interconnected by a Media Gateway. A control node obtains from a Home Subscriber Server, the identity of a Media Gateway Control Function controlling that Media Gateway which will terminate the call within the circuit switched access network. The first node calls an access number notified to it by the Media Gateway Control Function, and as part of the call setup procedure, the identity of the Media Gateway selected to terminate the call is communicated to the second node.
