Patent number: 11871340Abstract: Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.Type: GrantFiled: May 17, 2022Date of Patent: January 9, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Fuencisla Garcia Azorero, Susana Fernandez Alonso, Victor Ferraro Esparza, Angel Navas Cornejo, Ignacio Rivas Molina

Publication number: 20230013118Abstract: Methods performed in a core network (110) for dynamically handling access and mobility service areas with different capabilities in a communication system (100) are disclosed. The methods are carried out in an AMF node (111), a UDM node (112), a PCF node (113) and a SMF node (115). The UDM node (112) configures Service Area Restriction (SAR) data in a subscription data for a UE (120). The SAR data includes a number of service areas allowed or restricted for the UE and, for each service area, a service area identifier, a service area type and a service area definition. The PCF node configures a Service Area Definition (SAD) rule for a UE. The SAD rule comprises a service area definition and an indication of a set of service area characteristics enabled in the service area.

Patent number: 11457359Abstract: Methods and apparatus for controlling the transmission of user data over an NAS of a telecommunications network. An AMF includes a receiver configured to receive NAS policy control data determined by a PCF. The NAS policy control data identifies a user, is based on the user's subscription to the telecommunications network and includes one or more authorization parameters identifying whether the user is permitted to transmit user data over the NAS. The receiver also receives from a UE, or an AS, an NAS transmission request identifying the user and requesting transmission of user data over the NAS. An NAS transmission authorizer controls whether the transmission of the user data over the NAS should be authorized based on the authorization parameters and the NAS transmission request.Type: GrantFiled: July 6, 2017Date of Patent: September 27, 2022Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Susana Fernandez Alonso, Fuencisla Garcia Azorero, Angel Navas Cornejo, Ignacio Rivas Molina
