Abstract: There are provided measures for enabling/realizing external steering of access traffic multipath communication in a mobile communication system, e.g. an external access traffic multipath communication steering function. Some such measures include that a session management function element or instance in a mobile communication system initiates control of establishment of at least one user plane session for access traffic multipath communication, obtains communication information of an external steering function element or instance to be used for steering access traffic multipath communication in the at least one user plane session, creates access traffic multipath communication rules, forwarding action rules and multi access rules for access traffic multipath communication in the at least one user plane session, and provides the access traffic multipath communication rules and the communication information of the external steering function element or instance to the communication function element or instance.

Abstract: Techniques for providing more efficient onboarding traffic protocols in a standalone non-public network architecture are provided. A network entity includes processing circuitry and at least one memory including computer program code. The at least one memory and the computer program code configured to, with the processing circuitry, cause the network entity at least to generate one or more traffic filter rules for a traffic filter set. The one or more traffic filter rules or traffic detection rules are generated based at least in part on domain name service query response information related to one or more user device originated domain name service queries. The network entity may further be configured to cause a user plane function to be provided with the one or more traffic filter rules.

Abstract: There are provided measures for location based network access management. Such measures exemplarily comprise receiving a rejection message indicative of rejection of access of said mobile terminal to a first mobile network, checking for a cause of said rejection of access of said mobile terminal to said first mobile network, and affecting, if said cause of said rejection of access of said mobile terminal to said first mobile network is indicative of that said mobile terminal is not allowed to access to said first mobile network from a determined location of said mobile terminal, a selection of a second mobile network to be accessed based on a content of said rejection message.

Abstract: Techniques for improving the resiliency of communication networks by providing radio access network data stored in a radio access network database to one or more associated radio access network nodes are provided. A network entity receives a connection request from a user device including at least a radio access network set identifier or radio access network database identifier. The network entity determines whether the radio access network set identifier received in the connection request corresponds to an associated radio access network set identifier. In an instance in which the radio access network set identifier received in the connection request corresponds to the associated radio access network set identifier, radio access network database data are retrieved from the radio access network database associated with the radio access network set identifier. The radio access network database data include at least user device context data for the associated user device.

Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) on the path are provided. The method may include determining that an existing user plane function is sub-optimal in terms of routing and latency incurred with respect to traffic for a given packet data unit session of a user equipment. The method may also include establishing, based on the determination, a new user plane function for the packet data unit session. The method may further include establishing a branching point user plane function that interfaces with the existing user plane function, the new user plane function, and a plurality of network access types. In addition, the method may include updating the user equipment by providing the user equipment with relevant multi-access traffic steering rules.
