Abstract: In a service processing method, a capability exposure network element receives a first message from an application function network element, where the first message carries a terminal identifier and first network information of a first virtual network, the first network information includes a first virtual network identifier, and the first message is used to request to add a terminal corresponding to the terminal identifier to the first virtual network corresponding to the first virtual network identifier; and the capability exposure network element determines, based on the first network information, a first service management device serving the first virtual network, and sends a second message to the first service management device, where the second message carries the terminal identifier and the first network information, and the second message is used to request to add the terminal to the first virtual network.

Abstract: Embodiments of this application disclose a communication method including: An SMF network element receives a first application request for requesting to provide a service of a 5GVN for a first LAN in a data network, and the first application request carries address segment information of the first LAN, information that is about a target group and that corresponds to the first LAN, and interface information of a first tunnel interface of a first LSW in the first LAN. The SMF network element determines a first UPF network element that provides the service of the 5GVN and sends first routing information to the first UPF network element, where the first routing information indicates the first UPF network element to forward received first data to the first tunnel interface, and a destination address of the first data is any address included in the address segment information of the first LAN.

Abstract: Embodiments of this application provide a device and a system of a virtual network service across session management network elements. A group session management network element obtains tunnel information of a first user plane network element serving a first terminal device belonging to a first virtual network group, sends a first message to a second session management network element, where the first message includes an identifier of the first terminal device, an identifier of the first virtual network group, and the tunnel information of the first user plane network element for configuring a first forwarding rule on a second user plane network element, and the first forwarding rule is used by the second user plane network element to send a first data packet to the first user plane network element when one terminal device belonging to the first virtual network group sends the first data packet to the first terminal device.

Abstract: A Method and a system for performing a heartbeat adaptation process are disclosed herein. A computing device detects a condition for initiating the heartbeat adaptation process in accordance with one or more predetermined criteria. In response to detecting the condition, the computing device performs the heartbeat adaptation process by sending, to a server, one or more first heartbeat test packets according to a predefined time interval. If the one or more first heartbeat test packets satisfy one or more test continuation criteria, the computing device: increases the predefined time interval according to a predetermined interval step; and repeats the heartbeat adaptation process using the increased predefined time interval. If the one or more first heart test packages satisfy one or more test termination criteria, the computing device: identifies a stable heartbeat interval according to the predefined time interval; and terminates the heartbeat adaptation process.

Abstract: A network device is configured to receive a registration message from a private user device including a private internet protocol (IP) address associated with the private user device. A public IP address and discrete port number are assigned to the private user device and private IP address and stored in an incoming call table. The registration message is translated to include the public IP address and discrete port number. The registration message is forwarded to a proxy server for registration. An incoming call invitation message is received from a public user device, where the call invitation message is directed to the public IP address and discrete port number associated with the private user device. The call invitation message is translated to include the private IP address associated with the private user device based on the received public IP address and discrete port number and the incoming call table. The call invitation message is forwarded to the private user device.

Abstract: A signalling switch for use in information protocol telephony is provided, which can initiate, sustain, and terminate a plurality of discrete voice and data calls simultaneously. A plurality of cards are mounted on a computer bus, where the first card is a single board computer whose function is to act as the operations and maintenance control card for the switch. A non-system card functions as a message transport controller card; and there is at least one further non-system card which functions as a master application controller card. Local bus communication among the non-system cards is provided by a local bus found on the message transport controller card. Telephone routing information protocol software is resident in the switch, and the switch communicates externally via Ethernet interfaces.
