  • Patent number: 12212499
    Abstract: 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.

  • Patent number: 12041519
    Abstract: 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.

  • Publication number: 20240089710
    Abstract: A User configures the option in his/her UE to deliver the SMS via Operator's application client installed on UE. This configuration will be saved in the UDM as an option opted by UE. SMS-GMSC receives the “SMS delivery flag (indicating alternate delivery mechanism is enabled)” from UDM in response to the “Send Routing Infor for SM” message. If the traditional SMS delivery over mobile operator network fails (e.g. no connectivity), then SMS-GMSC will trigger NEF to re-attempt the SMS delivery to UE. (NEF can be an optional network function as Application function is trusted one and hosted in Operator's network). NEF sends the SMS to Application Function (Mobile Network Operator's Serer) which encrypts the SMS payload and delivers the SMS to operator's application client e.g. Mobile Network Operator App installed on UE over the alternative data connectivity (Ex. Wi-Fi Broadband).

  • Patent number: 11929938
    Abstract: 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.

  • Publication number: 20230156514
    Abstract: A method performed by first User Equipment (UE) for applying policy enforcement for data traffic in an UL data session is provided. The UL data session is from the first UE to a data network via a Radio Access Network (RAN) a Core Network (CN) and a first Network Slice (NS) in a radio communications network. The UE obtains first information from a CN node in the CN. Upon establishing the UL data session, the UE measures data traffic performance and radio conditions in the RAN. The UE predicts available resources for transmitting data from the first UE towards the data network via the RAN, the CN, and the first NS. The prediction is based on the obtained first information, the measured data traffic performance and radio conditions in the RAN. The UE then applies policy enforcement for the data traffic in the UL data session based on the prediction.

  • Patent number: 11606683
    Abstract: 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.

  • Publication number: 20230013118
    Abstract: 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. During a registration procedure, the SAR data and SAD rule may be provided to the AMF node upon request for a UE communication.

  • Publication number: 20220167211
    Abstract: According to certain embodiments, a method for use in a network node comprises receiving a request to connect a session of a wireless device. The wireless device is located in a service area of a Local Area Data Network (LADN) and a subscription associated with the wireless device permits access to the LADN. The method further comprises determining whether to select the LADN for the session. The determining is based on one or more factors associated with the LADN. The one or more factors comprise at least one of the following: loading conditions, service quality, historic data, and subscriber priority. The method further comprises sending, to another network node, a message indicating whether the LADN has been selected for the session.

  • Patent number: 10785634
    Abstract: 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.
