  • Publication number: 20210194749
    Abstract: There are provided methods for defining a Network Service Descriptor (NSD) for a Network Service (NS), and Network Functions Virtualization (NFV) Orchestrator (NFVO) using said NSD. The NSD comprises zero, one or more of each of: a Virtualized Network Function (VNF) Descriptor (VNFD), a Physical Network Function (PNF) Descriptor (PNFD), a Network Service Descriptor (NSD), a Virtual Link (VL) Descriptor (VLD), and a VNF Forwarding Graph Descriptor (VNFFGD). One method comprising the step of defining at least one Connection Points (CP) Profile, wherein the CP Profile is referenced through a cpProfileId in a Network Forwarding Path Descriptor (NFPD) attribute of the VNFFGD, the CP Profile specifying a Connection Point Descriptor (CPD) or Service Access Point Descriptor (SAPD) for a given VnfProfile, PnfProfile or NsProfile.

  • Patent number: 9510178
    Abstract: A method for a fallback core network node within core network nodes for a first mobile terminated call towards a mobile subscriber initially assigned to a failing ore network node (failing CNN). The method includes receiving data associated to International Mobile Subscriber Identity and Location Area Identifier (LAI) of a mobile subscriber handled in the failing CNN. The method includes receiving a service request from a home location register (HLR), whereby the service request indicates that the fallback CNN is acting as a fallback CNN for the failing CNN, and sending a response to the service request towards the HLR comprising the roaming Number assigned by the fallback CNN. The method includes initiating a paging request towards the radio network comprising said received LAI of said mobile subscriber, and sending a Service Request towards the HLR comprising the Mobile Station Integrated Services Digital Network Number of the mobile subscriber.

  • Patent number: 9014708
    Abstract: The present invention relates to a network entity for handling communications towards a mobile station over a communication network, the mobile station being capable of receiving a paging request from a mobile switching center of a pool of mobile switching centers, and, in response to the paging request, of transmitting a paging response over the communication network. The network entity comprises a receiver (101) for receiving the paging response, the paging response comprising mobile identity information identifying the mobile station, a processor (103) for identifying the mobile switching center to which to re-transmit the paging response upon the basis of the mobile identity information, and a transmitter (105) for retransmitting the paging response to the identified mobile switching center.

  • Publication number: 20130196640
    Abstract: According to the invention, it provides a Network Element (NE) acting as an originating NE for End-to-End (E2E) Circuit Service (CS) call tracing functionality, the NE comprising: a receiver configured to receive a trace activation message which contains trace control and configuration parameters, wherein the trace control and configuration parameters include at least a Trace Reference, a start triggering event, a stop triggering event, an E2E call tracing option and an address of a Trace Collection Entity; a storage device configured to store the trace control and configuration parameters received by the receiver; a trace data reporter configured to start a trace session with the Trace Reference, to start a Trace Recording Session with a Trace Recording Session Reference when the start triggering event occurs, and to record and output trace data according to the stored trace control and configuration parameters; and a sender configured to detect that the E2E call tracing option is included in the trace activ
