Abstract: A method of processing call establishment requests, the method comprising the steps of: a) receiving call establishment definition data relating to a called party identifier; b) receiving a call establishment request from a calling party, the call establishment request comprising the called party identifier; c) determining that a user terminal associated with the called party identifier is engaged in a call with a remote party; d) determining that call establishment definition data is associated with the called party identifier; and e) in response to steps b) c) and d), processing the call establishment request to connect the calling party to the called party.

Abstract: Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. Telephony network equipment in the telephony network receives, from the first telephony device over a signalling link, a telephony session establishment request. The telephony network equipment receives, from the first telephony device over a data link that is separate to the signalling link, a message comprising data useable by the telephony network equipment to identify the second telephony device. The telephony network equipment correlates the received telephony session establishment request and the received message. The telephony network equipment transmits, to the second telephony device, a telephony session establishment request on the basis of the correlating. The first telephony device is associated with a multi-persona user having a first persona associated with a first telephony identifier and a second persona associated with a second telephony identifier.

Abstract: Measures, including methods, systems and computer-readable storage mediums, for use in processing notifications relating to telecommunication sessions. A cluster of servers is operable to receive incoming notifications where each server can process any given notification and update a store holding records based on previous notifications. The cluster may include a timer function to allow records to be closed when no relevant notifications are received after a timeout interval.

Abstract: A network node has a graceful restart mode in which the node: sends a graceful restart notification to one or more neighbouring nodes; attempts to re-establish an adjacency with the neighbouring node(s); receives link state data from at least one of the neighbouring node(s), the received data being sent in response to said attempt; derives pre-restart link data from the received data, the derived data identifying formerly active links, including the node, for routing traffic before the restart; routes network traffic in accordance with routing information stored in the router; detects one or more links, of the formerly active links, which are currently inactive; continues with graceful restart after said detection; determines one or more links, of the formerly active links, which are currently active; and exits the graceful restart mode in response to successful re-establishment of adjacencies with a respective neighbouring node for each of the currently active link(s).

Abstract: A method of serving a network resource usage record file is disclosed. The method can comprise: storing network resource usage records in a distributed database, the network resource usage records relating to network resource usage in a telecommunications network; sending a file list identifying a network resource usage record file over a file retrieval interface without having constructed the network resource usage record file; receiving, over the file retrieval interface, a request for the network resource usage record file; constructing, in response to the receiving of the request, the network resource usage record file, the network resource usage record file comprising one or more network resource usage records obtained from the distributed database; and serving, over the file retrieval interface, the network resource usage record file.

Abstract: Measures, including methods, apparatus and computer programs, for use in operating a network node. A method includes, at the network node: receiving a session initiation protocol (SIP) message directed towards a downstream network element, wherein the received message comprises session description protocol (SDP) data indicating a first SDP preconditions setting; forwarding the received SIP message on to the downstream network element with no modifications; in response to forwarding the received SIP message, receiving a rejection message from the downstream network element; on the basis of the received rejection message, determining that the first SDP preconditions setting is not supported by downstream device; generating a second SIP message comprising SDP data indicating a second SDP preconditions setting different from the first SDP preconditions setting; and transmitting the generated second SIP message comprising SDP data indicating the second SDP preconditions setting to the downstream network element.

Abstract: A signalling protocol routing system comprising at least one routing service module and at least one rules processing module, the signalling protocol routing system being capable of accessing additional routing service modules and/or rules processing modules when required. The routing service modules convert protocol messages into deconstructed protocol messages, so that a rules processing module can apply routing rules to the deconstructed protocol messages and determine a route for a message.

Abstract: Measures, including methods, systems and non-transitory computer-readable storage mediums, for providing a Domain Name Service (DNS) configuration service for one or more network services provided in a cloud environment. Update data relating to one or more relationship updates that have occurred in at least one of the one or more network services is received. The one or more relationship updates relate to one or more service provision units in a cluster of service provision units deployed in the cloud environment to provide the at least one network service. DNS policy configuration data associated with the at least one network service is identified. On the basis of the identified DNS policy configuration data, data in a DNS configuration data database is updated.

Abstract: A message is processed at a node in a cluster of nodes. The message is received at the node. The message is addressed to at least one other node in the cluster. At least one action associated with the message is performed at the node. A response message is transmitted indicating that the at least one action has been performed.
