Abstract: A computer file is processed at a first network entity (NE). At least part of the file is received from a second NE. Data relating to the received at least part of the file is transmitted to a third NE and: (i) comprises a file name of the file, the file name being transmitted to the third NE before the first NE received at least one other part of the file; and/or (ii) indicates that the first NE is processing the at least part of the file; and/or (iii) indicates that the first NE is in the process of receiving the file. Confirmation data is received from the third NE, confirming that the third NE has received the transmitted data. A file transfer acknowledgment is transmitted to the second NE on the conditions that the first NE (i) has successfully received the file and (ii) has received the confirmation data.

Abstract: Traffic is processed in a virtualised environment comprising: (i) a physical underlay network; (ii) a first overlay network (an overlay of the physical underlay network and associated with a first set of network addresses, IP1); (iii) a second overlay network (an overlay of the first overlay network and associated with a second set of network addresses, IP2); and (iv) virtualised applications each having an execution environment and being associated with at least one network address in each of the first and second sets of network addresses, IP1 and IP2. In the execution environment of a first virtualised application: (i) traffic communicated from the first virtualised application to the first overlay network is encapsulated; and/or (ii) traffic communicated from the first overlay network to the first virtualised application is decapsulated. Tenant separation processing is performed outside the execution environments of the virtualised applications.

Abstract: Measures for providing timer services in a network including a cluster of nodes responsible for providing timer services to clients. At a given node in the cluster, a request to provide a timer is received from a client. Configuration of a primary replica of the requested timer on a first node in the cluster to pop after a first time has elapsed is initiated. A first timer replication message is transmitted to a second node in the cluster, the first timer replication message indicating that the second node should configure a first backup replica of the requested timer. A second timer replication message is transmitted to a third node in the cluster, the second timer replication message indicating that the third node should configure a second backup replica of the requested timer. Popping of the primary, first backup or second backup timer replicas includes initiating callback of a given client.

Abstract: Data is processed in a telecommunications network. First and second notifications are received, via an input interface, from first and second Charging Trigger Functions, CTFs, in the telecommunications network. The first and second notifications relate to network resource usage in the telecommunications network. A scalable transformation function is used to transform data derived from the first and second notifications into a first usage detail report in a first detail report format and a second usage detail report in a second, different detail report format. The first and second usage detail reports are output, via an output interface, to at least one recipient system.

Abstract: Certain aspects provide a method of commissioning a virtualized network function (VNF), including: at a commissioning virtual machine instantiated in a virtualized environment of a customer network, configuring a remote access connection facility for accessing the commissioning virtual machine remotely from outside of the customer network, wherein the commissioning virtual machine has access to a virtual infrastructure manager (VIM) component of the virtualized environment; causing, via the remote access connection facility, configuration of a VNF manager component within the commissioning virtual machine; and causing, via the remote access connection facility, the configured VNF manager component to instruct the VIM component to instantiate one or more virtual machines in the virtualized environment, the one or more virtual machines being operable to perform at least a part of the VNF.

Abstract: A method of operating a user terminal in a telecommunications network. A telephony call is established between a first user, associated with the user terminal, and a remote user. Data communications is conducted between the user terminal and a communications server, such that the user terminal has a first connection to a communications session associated with a communications server. The telephony call is manipulated such that the telephony call forms a second connection to the communications session. Both the first connection and the second connection are maintained, for conducting communications between the first user and the remote user. The second connection may be terminated after assessment is made that the first connection is likely to provide better quality of service.

Abstract: A packet processing node and method in which an input of the node receives data and control packets, and an output of the node sends data and control packets. A node includes a control plane function to process control packets, and a forwarding function configured to receive data and control packets via the input, to forward received data packets to the output, and to forward received control packets to the control plane function. The control plane function is configured to receive the control packets, and to determine which control packets are to be processed by the control plane function, and which control packets are to be processed externally.

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.
