摘要： There are provided methods, arrangements and entities for an Access and mobility Function, AMF, and for a NF Repository Function, NRF in a 5G supporting Communication Network, CN, providing services to a User Entity. Also, a NF Repository Function, NRF, is described. A request (2A) for SMF information to the NRF to retrieve at least a list of SMFs that supports the DNN and optionally which network slices each SMF supports is transmitted.

摘要： Systems and methods relating to a cellular communications system having an architecture in which Serving Gateway (SGW) user plane functionality is separated from SGW control plane functionality are disclosed. In some embodiments, a cellular communications system having an architecture in which SGW user plane functionality is separated from SGW control plane functionality comprises a Serving Gateway Control plane entity (SGW-C) partitioned into a plurality of virtual SGW-Cs that correspond to a respective plurality of SGW User Plane (SGW-UP) service areas. The cellular communications system further comprises a plurality of SGW-UP pools each comprising one or more SGW User entities (SGW-Us), wherein each SGW-UP pool serves a respective one of the plurality of SGW-UP service areas. In this manner, the coordination problem between Tracking Areas (TAs) and the SGW-UP service areas is avoided.

摘要： A method implemented in a control node includes receiving a message from a first node. The method further includes determining whether the received message corresponds to one or more network partitions based at least in part on the partition selection information. The method further includes selecting, in response to determining that the message corresponds to the one or more network partitions, a particular network partition from the one or more network partitions using the partition selection information, and routing the message to a second node associated with the selected particular network partition.

摘要： According to one aspect of the present disclosure, a method of paging policy differentiation in a 5G telecommunications network is provided. A User Plane Function (UPF) receives downlink data for a target User Equipment (UE), and provides a data notification to a Session Management Function (SMF), the data notification comprising a Quality of Service (QoS) indicator, which the SMF uses to determine QoS Information (QoSI) that is sent to an Access Management Function (AMF). The AMF determines whether a paging policy selection should be performed by the AMF or by a Radio Access Node (RAN) that serves the target UE: if by the AMF, the AMF selects a paging policy based on the QoSI and sends a paging message to the RAN, which pages the UE; if by the RAN, the AMF provides paging policy information to the RAN, which selects a paging policy and pages the UE accordingly.

摘要： A first network node controls WLAN accesses and a second network node controls cellular network accesses. The first network node (NN) records a time of a last radio contact event of a user equipment (UE) with respect to a WLAN access controlled by the first NN. In response to a request from a third NN, the first NN indicates the recorded time of the last radio contact event to the third NN. The second NN records a time of a last radio contact event of the UE with respect to a cellular network access controlled by the second NN. In response to a request from the third NN, the second NN indicates the recorded time of the last radio contact event to the third NN. The third NN can use the indicated times to determine whether the UE is attached to a WLAN access or to a cellular network access.

摘要： The disclosure relates to a method (20) performed in a communication device (2). The method (20) comprises obtaining (21) a policy comprising one or more rules associated with different values of a parameter, the parameter comprising a first part and a second part; receiving (22) the parameter; and applying (24, 26) a rule associated with a value of the first part of the parameter or a rule associated with a value of the second part of the parameter. The disclosure also relates to a corresponding method in a communication system (1), to a communication device (2), a communication system (1), computer programs and computer program products.
