摘要
Embodiments of the present invention provide a method, an apparatus, and a network system for a terminal to traverse a private network to communicate with a server in an IMS core network. The method for a terminal to traverse a private network to communicate with a server in an IMS core network includes: setting, by the terminal, a source address of service data to be sent as a virtual IP address, setting a destination address of the service data to be sent as an address of an internal network server, and obtaining a first service packet, where the virtual IP address is an address allocated by the multimedia subsystem IMS core network to the terminal; and encapsulating, by the terminal, the first service packet into a first tunnel packet, and send the first tunnel packet to the security tunnel gateway over a virtual private network tunnel (VPN) between the terminal and a security tunnel gateway, so that the security tunnel gateway sends the first service packet in the first tunnel packet to the internal network server. By using the technical solution provided in the embodiments of the present invention, the terminal is capable of traversing the private network to communicate with the server in the IMS core network without modifying an enterprise network.
