Abstract: A method for the communication of data with respect to at least two telephony user devices in a data communications network comprises determining call party details for a telephone call. The telephone call involves at least a first device and a second device. The call party details include first and second identities associated with the first and second devices respectively. A separate communications session is established on the basis of the first and second identities. The communications session is separate from the telephone call and is for the communication of data to and/or from the at least two devices. An alert activation request for an alert mechanism associated with the at least one of the at least two devices is transmitted via the communications session. The alert activation request is capable of causing the at least one of the at least two devices to activate the alert mechanism.

Abstract: Processing data in a communications system comprising a plurality of servers is provided. First data received from a communications device is directed to a given server in the plurality of servers. A server identifier identifying the given server is transmitted to the communications device. Subsequent data is received from the communications device. The subsequent data comprises the server identifier and a further parameter. The given server is selected on the basis of at least the server identifier and some of the subsequent data received from the communications device is directed to the given server. In the event of a need to redirect subsequent data to a server other than the given server, a different server is selected on the basis of at least the further parameter and further of the subsequent data received from the communications device is directed to the selected different server.

Abstract: Nodes in a tree data structure are associated with respective node keys. At least some of the nodes are associated with at least one respective node rank. The structure is searched to attempt to identify a preferred prefix-matching node on the basis of attempting to find a prefix-matching node that has a prefix match with a search key and which has a preferred node rank relative to a node rank associated with a node which may have a longer prefix match. If the prefix-matching node is identified, a dependent node rank identifier associated with the prefix-matching node is used to determine that the prefix-matching node has the preferred node rank. The dependent node rank identifier indicates at least a node rank of a node which may have a longer prefix match than the prefix-matching node. The prefix-matching node is selected, if identified, as a preferred prefix-matching node.

Abstract: Methods, apparatus and computer program products for processing signaling information for telephone call attempts in a packet-based telephony service. An overload protection node is introduced to protect a signaling node from an overload of signaling information for telephone call attempts. A characteristic of signaling information for telephone call attempts in the packet-based telephony service is monitored by the overload protection node and on the basis of the monitored characteristic, the overload protection node processes signaling information for telephone call attempts according to one of a number of different modes of operation. A mode of operation may involve transmitting signaling information for a call attempt to the signaling node or selecting one or more call attempts at the overload protection node for the purpose of reducing overload in the signaling node.

Abstract: A method of routing a call involving a call party in a telecommunications network via a selected media routing path of a plurality of different media routing paths is provided. The media routing paths communicate media data to and/or from at least one communication device associated with the call party. A call control system in the telecommunications network receives data derived from a media quality test procedure for a given media routing path. The media quality test procedure includes media test data being communicated via the given media routing path and the media test data being analysed. The call control system selects a preferred media routing path from the plurality of media routing paths for communicating media data associated with the call to and/or from one or more of the at least one communication devices associated with the call party on the basis of at least the received data.
