  • Patent number: 11363524
    Abstract: 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.

  • Patent number: 11191088
    Abstract: An apparatus for user plane function, UPF, allocation is described. The UPF is configured to provide a Protocol Data Unit, PDU, connectivity service between a terminal device and a data network on a user plane, and the allocation is based on control information associated with an individual logical PDU entity. The control information defines priority information indicative of a priority of the PDU entity relative to other PDU entities and pre-emption information indicative of at least one of whether the PDU entity is capable of being pre-emptively allocated to a UPF over other PDU entities served by that UPF, and whether the PDU entity when served by a UPF is vulnerable to being re-allocated for pre-emptively allocating other PDU entities to that UPF.

  • Publication number: 20210153018
    Abstract: 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.

  • Patent number: 10681086
    Abstract: A method aims at providing a service in a communication network, and comprises the following steps. An access to a service requiring authentication is initiated by a UE (100), An identity management node (300) authenticates the UE, and then sends, to a PCRF node (400), a message comprising: service information for identifying the service to which access is initiated, identification information for identifying the UE, and authentication information determined upon authenticating the UE. The PCRF node determines control rules to be applied to the service for the UE, based on the authentication information and service information. The PCRF node then triggers installation of the control rules in at least one network node (500) handling service data flows (SDF) for the service, to enforce the control rules on traffic associated with the service for the UE. The invention also relates to devices and computer programs for carrying such as method.

  • Patent number: 10673817
    Abstract: The invention relates to a method, by a policy controller 100, for generating policy rules for data packet flows in a communications network. The policy controller 100 has access to a policy database 130 and stores a service level agreement. The service level agreement contains a plurality of different service level identifiers, each service level identifier being associated with a set of conditions that govern the policy rules to be applied to the data packet flows in the communications network. The method comprises the following steps: An authorization request is received for a data packet flow, the authorization request comprising service information for a service and a service level identifier. The policy database 130 is accessed and the set of conditions associated with the received service level identifier is determined. Further, based on the determined set of conditions, a policy rule to be applied to the data packet flow is generated.

  • Patent number: 9769648
    Abstract: A method is proposed of provisioning connectivity service data for a device when the device attaches to a telecommunications network. The connectivity service data comprises information required to enable connectivity between the device and at least one further device of the network. Dynamic data relating to the device is obtained as part of one of the device attaching to the telecommunications network and a previous attachment of the device to the network. The dynamic data is of a type that may change from one such attachment to another such attachment of the same device. The connectivity service data is then selected based on the obtained dynamic data. It is then arranged for the selected connectivity service data to be provisioned to the device.
