A data forwarding method includes receiving, by a session management function network element, information about a first bearer in a first network from an access and mobility management function network element; and sending flow information of a first flow in a second network and forwarding information to the access and mobility management function network element. The flow information indicates a flow for data forwarding, and the forwarding information is used for forwarding the first flow to a tunnel corresponding to the first bearer.

During PDN connection establishment in the EPC, a UE and a session managment entity (SME) (e.g., PGW-C+SMF) exchange information. In case the SME supports more than one S-NSSAI, before the SME provides an S-NSSAI to the UE, the SME should check such that the selected S-NSSAI is among the UE's subscribed S-NSSAIs by retrieving the Subscribed S-NSSAI from a UDM using, for example, the Nudm_SDM_Get service operation.

Method performed by a communication device (10) for handling communication in a communication network comprising at least a first wireless communication network (11) and a second wireless communication network (14), which communication device (10) is served by a radio network node (13) in the second wireless communication network (14). The communication device (10) performs a preparation signaling, via the radio network node (13) and transparently through the second wireless communication network (14), to a first network node (12) of the first wireless communication network (11) for preparing the first network node (12) with a pre-configuration for serving the communication device (10).

Connecting user equipment (UE) to an application can be managed based on UE movement and location. During data session between UE and application, a communication management component (CMC) associated with anchor network component (ANC) or serving network component (SNC) determines UE location, and connects UE to the ANC and SNC, which enables access of the application via a data network associated with ANC. As UE moves, CMC tracks UE movement and communication conditions. If, when UE is at second location, a communication condition breaches threshold level, CMC determines whether interruption of the data session is permitted. If not, CMC determines whether there is a local SNC in proximity to second location. If there is, CMC can switch UE from SNC to local SNC, which can access local application content via local data network associated with application. If interruption permitted, UE deactivates and reactivates to connect to local ANC.

Methods and apparatuses for reducing application instantiation delay and downtime are described herein. A method may comprise relocating an application function from a source Edge Data Network (EDN) component to a target EDN component. The method may comprise receiving an indication, and/or determining, based on at least one of a user mobility, resource optimization requirement, key performance indicator (KPI), or a failed relocation attempt, to relocate the application function. The method may further comprise performing a Protocol Data Unit (PDU) session establishment procedure toward the target EDN component. The method may further comprise determining, based on one or more received parameters for edge usage and capabilities, to relocate the application function. The method may further comprise sending, to a European Telecommunications Standards Institute (ETSI) Multi-access Edge Computing (MEC) orchestrator, an indication that the application function will be relocated. The application function may be a User Plane Function (UPF).

Aspects presented herein may improve an emergency call establishment procedure by enabling a UE to transmit emergency register messages more efficiently. In one aspect, a UE transmits, to a network entity, a request to set up an ePDN. The UE receives, from the network entity, a response to the request comprising a set of multiple P-CSCF addresses. The UE transmits, to the network entity, a registering message to each of the multiple P-CSCF addresses simultaneously. The UE receives, from the network entity, at least one acceptance message from at least one of the set of multiple P-CSCF addresses in response to the registering message. The UE transmits, to the network entity, an invitation message to a P-CSCF address from which an acceptance message is received to establish an emergency call connection.

A handover method includes receiving a handover requirement message from a source access network device, and sending a handover request message to the target access network device. The handover requirement message includes an identifier of a session of a terminal device. The session is to be handed over from the source access network device to a target access network device. The handover request message includes first single network slice selection assistance information (S-NSSAI). A first network slice of the target access network device that corresponds to the first S-NSSAI serves the session. The first S-NSSAI is determined based on second S-NSSAI and the first network slice supported by the target access network device, and the second S-NSSAI is of a second network slice of the source access network device and that corresponds to the identifier of the session.

Techniques are provided to use a trusted identity and location to select the most appropriate point of interconnect to edge application execution environments as well as a specific edge application execution environment. The techniques may involve obtaining, on behalf of a wireless mobile device, an access identifier that indicates an access location of the wireless mobile device that is wirelessly connected to wireless network infrastructure equipment operated by an access network provider that is associated with, and a member of, a federation of access network providers. The access location for the wireless mobile device is derived based on the access identifier, and the access location is used to select an edge resource to be used by the wireless mobile device.

Disclosed are a UE route selection method and related products, which are applied to an electronic device. The electronic device includes at least one device application. The method includes the following. An electronic device pre-configures a path descriptor parameter corresponding to each device application. When receiving a service enablement request from a target application, the electronic device determines a target path descriptor parameter according to the service enablement request, and then determines a target route according to the target path descriptor parameter.

A device, method, and system provide for collecting service parameters associated with application sessions associated with a plurality of MEC clusters; obtaining capability information associated with each of the plurality of MEC clusters; generating service profiles for a set of transport networks based on the service parameters and the capability information, wherein each transport network includes at least one of the plurality of MEC clusters; receiving, from a user equipment (UE) device, a request for a MEC service having a minimum service requirement; and selecting, based on the service profiles, a MEC cluster from the plurality of MEC clusters to provide the MEC service, wherein the selected MEC cluster is included in a first transport network that meets the minimum service requirement.
