Implementations are described herein for wireless communication network handovers. One or more components of a visited public land mobile network (VPLMN) may send, to a packet data gateway (PGW) of a home public land mobile network (HPLMN), a create session request. The PGW of the HPLMN may send, to the one or more components of the VPLMN, a create session response that includes an identifier of the PGW. A mobility management entity (MME) of the VPLMN may send, to a home subscriber service (HSS) of the HPLMN, the PGW identifier. The HSS may use the PGW for a handover process, such as a handover from voice over Internet Protocol (VoIP) to voice over wireless local area network (WLAN).

A method, a network device, and a non-transitory computer-readable storage medium are described in relation to a low latency, low loss, and scalable throughput (L4S)-triggered prioritized connection service. The L4S-triggered prioritized connection service may enable an evolved packet data gateway (ePDG) to provision prioritized and non-prioritized tunnels with end devices via untrusted wireless local area networks. The prioritized tunnel may support L4S or another quality of service in which the ePDG may provide prioritized data forwarding. The end device may transmit a request that includes priority data.

The present disclosure provides a voice service configuration method and device, electronic equipment and storage medium, and relates to the technical field of wireless communication. The method comprises the following steps: obtaining a response message sent by an evolved packet data gateway (ePDG), wherein the response message comprises whether to carry back-off timer information; judging whether the response message carries the back-off timer information; if yes, stopping initiating a request for accessing a voice over WiFi (VoWiFi) network within a time limited by the back-off timer information according to the back-off timer information; and if no, stopping initiating the request for accessing the VoWiFi network. The present disclosure obtains the timer information of the response message sent by the ePDG, formulates a voice service configuration method according to the timer information, and avoids that the user does not open the VoWiFi service, thereby increasing the network resource pressure caused by the terminal constantly trying to access the VoWiFi network.

Systems and methods described herein enable 5G core session management function (SMF) / user plan function (UPF) relocation to support ATSSS-enabled evolved packet data gateways (ePDG). An ePDG receives an access traffic steering, switching and splitting (ATSSS) trigger message from a user equipment (UE) device. The UE device is connected via a first session using a session management function (SMF) and a via a second session using a packet data network gateway (PGW). The ATSSS trigger message includes an SMF identifier for the SMF. The ePDG sends, in response to the ATSSS trigger message, a request to the SMF to merge the first session and the second session into a single registration.

Provided in the present application are a communication method, and a device and a storage medium. The communication method applied to a packet data gateway comprises: sending a first discovery request message carrying at least first capability-related information to discover a first network element, wherein the first capability-related information is capability-related information supported by the first network element; and selecting, on the basis of a received first discovery response message, the first network element matching the first capability-related information.

Provided are a message forwarding method, a UPF selection method, an electronic device and a storage medium, the message forwarding method comprising: sending a first message to an evolved packet data gateway (ePDG), the first message carrying a communication capability identifier of a UE, the communication capability identifier being used for determining that the UE supports separation of a control plane and a media plane; a second message sent by the ePDG is received, the second message carries address information and a security parameter index SPI corresponding to a target user plane function UPF, and the target UPF supports separation of a control plane and a media plane; generating a first target message according to the SPI of the target UPF; and directly forwarding the first target message to the target UPF based on the address information of the target UPF. In this way, in the link of receiving the address information of the target UPF and the real-time call of the SPI, the UE can further directly send the first target message to the target UPF with the address information of the target UPF and the SPI as identifiers, and the message information in the actual call does not need to be forwarded through the ePDG, thereby effectively reducing the transmission delay in the message communication transmission.
