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.

Methods and systems for exposing the network slice selection process to the entities within or attached to a client device are provided. According to one aspect of the present disclosure, a method for allowing slice consumers within or attached to the client device to access and use Network Slice Selection Assistance Information (NSSAI) comprises, at a client device: receiving, at an Application Programming Interface (API) layer within the client device, a query for NSSAI, the query being sent by a slice consumer; sending, to a Fifth Generation modem within the client device, the query for NSSAI; receiving, from the 5G modem, a response to the query for NSSAI; and sending, to the slice consumer, the response to the query for NSSAI. Enhancements to the N1 interface as well to Core Access and Mobility Management Function (AMF), Application Function (AF), and Network Exposure Function (NEF) are presented.

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.

Systems and methods for investigating and addressing excessive battery drainage in a wireless device in a cellular communications system are disclosed. In some embodiments, a method in a core network of a cellular communications system comprises receiving, from an external entity, a request to investigate excessive battery drainage at a particular wireless device and initiating collection of information related to operation of the wireless device. The information comprises user plane data, control plane information, and/or network information related to the wireless device. The method also comprises collecting the information from one or more network nodes in the cellular communications system, analyzing the collected information to determine one or more root causes of excessive battery drainage at the wireless device, and initiating one or more actions in the cellular communications system to mitigate excessive battery drainage at the wireless device.

Methods and systems for performing multi-domain network slice selection and approval are provided. According to one aspect, a method performed by a Network Slice Selection Function comprises: receiving, from a requesting entity, a request for a network slice for use by a client device; upon determining that the network slice selection requires approval, identifying an Authorizing Network Function (ANF) for authorizing a network slice for the client device; determining a trust status of the ANF; identifying, based on the trust status, a network interface to use when communicating with the ANF; sending a slice selection authorization request to the ANF via the identified network interface; receiving from the ANF an approval status of a network slice; determining, based on the approval status and approval conditions, an allowed network slice; and sending, to the requesting entity, information including the allowed network slice.

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.
