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 determining a registration area are provided. A network entity may receive one or more indications of topology information from one or more radio access network nodes. Each indication of topology information is related to one or more tracking areas and each tracking area is associated with one or more cells in a radio access network served by each of the one or more radio access network nodes. The network entity may determine a registration area based at least in part on the received one or more indications of topology information related to the one or more tracking areas.

Abstract: Various aspects described herein relate to apparatus, methods, and computer programs for retrieving an identifier of a subscription network of a mobile subscriber in a communication system. For example, one such method includes registering with a network repository function network function as a mobile number portability network function providing a service allowing a consumer to retrieve an identifier of a subscription network of a mobile subscriber. This method also includes receiving a request from the consumer to retrieve the identifier of the subscription network of the mobile subscriber. This method further includes sending a response to the consumer comprising information to retrieve the identifier of the subscription network of the mobile subscriber.

Abstract: Systems, methods, apparatuses, and computer program products for load and/or overload control in 5GC SBA are provided. One method may include transmitting, from a network function (NF) service consumer, overload control information (OCI) comprising scope information to a network function (NF) service producer or service communication proxy (SCP). The scope information may include at least one of: scope set to a notification uniform resource identifier (URI), or scope set to one of network function (NF) service instance, network function (NF) service set, network function (NF) instance, or network function (NF) set, and optionally a service name.

Abstract: Systems, methods, apparatuses, and computer program products for determination of non-3GPP interworking function(s) (N3IWFs), which support slices targeted by a device or user equipment (UE), are provided. One method may include transmitting, by a UE or device, a request to at least one network node. The request may be to obtain information on network slices supported by at least one N3IWF. The method may also include receiving, from the at least one network node, a response comprising information for one or more N3IWFs and, based on the received information for the N3IWF(s), selecting one of the N3IWF(s) to use to connect to a 5G core network (5GC).

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.

Abstract: Systems, methods, apparatuses, and computer program products for access traffic steering, switching, and splitting (ATSSS) with branching point (BP) or uplink classifier (ULCL) on the path. The method may include, setting up, in response to a request, a first user plane function with multi-access traffic steering functionality. The method may also include requesting a user equipment to establish a new multi-access packet data unit session to a same data network name and slice as an old multi-access packet data unit session, or request the user equipment to release the old multi-access packet data unit session with a second user plane function and to initiate a multi-access packet data unit session re-establishment. The method may further include sending, to the user equipment, multi-access rules for the new multi-access packet data unit session, a new internet protocol address, and new multipath transmission control protocol proxy information.
