Abstract: A network entity comprises an interworking function. The network entity is between an endpoint and a registrar in a telecommunications network. A message is received for the registrar from the endpoint, the message comprising data identifying an endpoint characteristic of the endpoint. A message is received for the endpoint. A processing action to be used to process the received message for the endpoint is determined based on the data identifying the endpoint characteristic of the endpoint comprised in the received message for the registrar from the endpoint. The received message for the endpoint is processed in accordance with the determined processing action.

Abstract: A network function operable in a communication network, in which the network function is configured to receive a call setup request from an emergency service to set up a call between the emergency service and a user terminal, the received call setup request comprising a called party identifier. The network function determines whether the called party identifier is of a first type or of a second, different type, wherein the first type of called party identifier comprises a dialable number temporarily associated with the user terminal for use in receiving a call from the emergency service. In response to determining that the called party identifier is of the first type, the network function transmits priority indication data to a further network function in the communication network in order to cause the further network function to prioritize handling of the call between the emergency service and the user terminal.

Abstract: A network node, during setup of a communication session between a calling party and at least a called party, receives a first provisional response message from a first device comprising first session description protocol (SDP) data; and forwards it on to a calling party device associated with the calling party, the forwarded first provisional response message comprising at least a part of the first SDP data. The network node receives a second provisional response message comprising second SDP data from a second device. Responsive to receipt of the second provisional response message, the network node transmits, during communication session setup, a message to the calling party device which offers to update the SDP data; removes the second SDP data from the second provisional response message; and transmits the second provisional response message from which the second SDP data has been removed to the calling party device.

Abstract: Measures for use in processing data in a telecommunications network. A request message is received in relation to establishment of a communication session involving a given subscriber. Subscriber configuration data is received in relation to the establishment. The subscriber configuration data includes a set of one or more trigger points at which one or more application services should be invoked in relation to communication sessions for the given subscriber. At least one trigger point from the set of trigger points is encoded into an identifier for the communication session within the request message. The request message including the identifier for the communication session in which the at least one trigger point has been encoded is transmitted.

Abstract: Measures, including methods, systems, non-transitory computer-readable storage mediums and computer programs for use in routing packet data. At a network switching device, a data packet is received from a device located upstream of the network switching device. The received data packet comprises routing data associated with a routing decision which has been taken for the data packet upstream of the network switching device. The routing data comprises an abstract media access control (MAC) address corresponding to a next hop destination for the data packet located downstream of the network switching device. At the network switching device, the abstract MAC address in the data packet is replaced with a real MAC address of the next hop downstream destination. At the network switching device, the data packet is forwarded towards the next hop downstream destination.

Abstract: A telephony signalling element and method with a signalling processing function and a session datastore function. The signalling processing function has associated functions that are provided by one or more instantiations, and the session datastore function has associated functions that are provided by one or more instantiations. The instantiations allow for independent scalability of the functions in the telephony signalling element.

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 plurality of network nodes are configured to form a virtual logical network over a plurality of broadcast domains. Configuring the virtual logical network includes configuring at least one of the nodes in the plurality of nodes to broadcast routes to IP addresses hosted on nodes in the plurality of network nodes between nodes in the plurality of broadcast domains. A primary workload hosted on a first node in the plurality of nodes is configured to share ownership of an IP address with a secondary workload hosted on a second node in the plurality of nodes. In response to detecting a failure indication associated with the primary workload, an IP address failover procedure for the shared IP address is performed between the primary workload and the secondary workload.

Abstract: A controller node receives a list of a first plurality of flows programmed on a network switch. The controller node extracts a flow cookie value from a flow cookie data field of each flow in the first plurality of flows on the received list and calculates a session identifier on the basis of the extracted cookie values. At least one add flow command is transmitted from the controller node to the network switch to program a second plurality of flows on the network switch. The at least one add flow command comprises flow cookie values in the flow cookie data fields of each of the flows in the second plurality of flows which are set equal to the calculated session identifier. At least one delete flow command is transmitted from the controller node to the network switch to delete programming of the first plurality of flows on the network switch.
