Methods performed in a core network () for dynamically handling access and mobility service areas with different capabilities in a communication system () are disclosed. The methods are carried out in an AMF node (), a UDM node (), a PCF node () and a SMF node (). The UDM node () configures Service Area Restriction (SAR) data in a subscription data for a UE (). 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. During a registration procedure, the SAR data and SAD rule may be provided to the AMF node upon request for a UE communication. The AMF node then takes actions for the UE communication based on anyone of the SAR data, the SAD rule and local policies at the AMF node. During a session management procedure, the SMF node () receives service area related information with a service area identifier and a service area type from the AMF node, and receives the SAD rule from the PCF node. The SMF node () then take actions for the UE communication based on the SAD rule, the information received from the AMF node () and/or local policies at the SMF node.

A method for managing traffic processed by a target network function of a communication network is disclosed. The target network function transmits and receives traffic over a communication channel that carries traffic between network functions and application functions. The method, performed by a Data Analytics Function (DAF) of a communication network, comprises receiving information about traffic flows over the communication channel, establishing a priority amongst traffic flows over the communication channel, based on the received information, generating a recommendation for traffic processing on the basis of the established priority, and sending the generated recommendation to a function in the network that has a management responsibility for the target network function.

Methods and apparatus are provided for network slice configuration. In one example aspect, a method in a network function in a network is disclosed. The network is a visited network for at least one User Equipment, UE. The network provides a network slice for the at least one UE, and the network function is a gateway for data communications for the at least one UE. The method includes obtaining an IP address for at least one service for the at least one UE, and providing the at least one service to the at least one UE according to a gateway configuration from a home network of the at least one UE.

Methods and systems for an online charging system to grant resources to a session with a terminal device when the session includes a large file or the session has a long duration. Embodiments the invention include methods performed by an electronic device for online charging in a wireless network. In one embodiment, the electronic device receives a request message for resources to set up a session with a terminal device, where the request message is sent from a core network interface to an online charging function (OCF), and where the request message indicates that the session includes a large file or that the session has a long duration. The electronic device determines that the terminal device has enough credit for the session based on the request message and grants the resources for the session with the terminal device based on the determination.

A first network node in a communication network can evaluate whether to scale a first resource of a network slice of the communication network. The first network node can receive, from a second network node of the communication network, a first message indicating a request for approval to scale the first resource of the network slice. Responsive to receiving the first message, the first network node can determine whether to scale the first resource of the network slice based on information regarding a second resource. The first and second resources may be of different types. The first network node can transmit, to the second network node, a second message indicating whether to scale the first resource of the network slice based on determining whether to scale the first resource of the network slice. Related methods are also discussed.

A method, performed by a first node is described, the method being for handling roaming information. The first node operates in a first communications network. The first node determines a set of network resources predicted to be required by a group of subscribers while roaming in a second communications network. The first node then initiates providing an indication of the determined set of resources to a second node in the second communications network. The second node receives the indication and determines whether or not an allocation of the set of resources meets a criterion. The second node then initiates performing an operation based on the determination. A third node determines data regarding a roaming behavior of the group of subscribers and provides information based on the determined data, to the first node.

Methods and systems for End-to-End (E2E) User Equipment (UE) trajectory network automation are herein provided. According to one aspect, a network node for E2E UE trajectory network automation, such as a Network Data Analytics Function (NWDAF), receives, from a requesting entity, information identifying a future E2E UE trajectory, the E2E UE trajectory comprising a start location, an end location, and zero or more intermediate locations between the start location and the end location; calculates a E2E mobility trajectory prediction for the identified future E2E UE trajectory; and sends, to the requesting entity, the calculated E2E mobility trajectory prediction. The requesting entity may be a trusted entity or an untrusted entity, such as a Third Party Provider (3PP) outside of the trusted domain of the network. If the requesting entity selects a mobility trajectory, the network node sends mobility management and optimization information to a Radio Access Network node.
