Embodiment 1

[0073] Embodiment 1 uses interworking between an IMS network and a heterogeneous network as an example to illustrate a schematic structural diagram of a network interworking device in the present invention.

[0074] As shown in Figure 3, the IMS network is the sending side, and the heterogeneous network is the receiving side. The call session control unit is the core network element in the IMS network, and performs functions such as session control and registration service. In the IMS network, the call session control unit and the receiving unit 61 are connected through the SIP protocol, and the sending unit 64 is connected with the heterogeneous network through the E1 interface. The sending unit 64 can be connected to a heterogeneous network through other network interworking devices, and an E2 interface is used between the sending unit 64 and other network interworking devices. The network interworking device will complete the signaling translation function between the SIP ...

Embodiment 4

[0107] In Embodiment 4, when the communication system includes two network interworking devices, the IMS network is used as the sending side, and the traditional circuit network is used as the receiving side. A user in the IMS network initiates a fire alarm emergency call, and the public safety access point (PSAP) is located in the traditional In the case of a circuit network, the difference from Embodiment 3 is that the service identifier identified by the second network interworking device in Embodiment 4 is different from that in Embodiment 6, as shown in Figure 7. In this case, two network interworking devices The steps to realize the intercommunication between the two ends of the network are as follows:

[0108]Step 701: A user initiates a fire alarm emergency call at the IMS network side, and the user terminal inserts a fire alarm emergency service identifier into a fire alarm emergency communication command after detecting the fire alarm emergency call. The method of in...

Abstract

This invention discloses a method for intercomunication of networks including: a communication order containing ID of first network service is sent to the first network side, which finds out an ID of a second network side corresponding to the ID of the first according to the corresponding relation of the two ID and transfers the ID containing the second network service to the second network side. This invention also discloses a device intercommunicating among different networks and a communication system.

Description

technical field [0001] The invention relates to data transmission technology in the communication field, in particular to a method and a communication system for intercommunication between different networks. Background technique [0002] The Internet Protocol (Internet Protocol, IP) Multimedia Subsystem (IMS) is defined by the 3rd Generation Partnership Project (3GPP) standard, and it is the third generation (3rd Generation, 3G) mobile network that implements packet Voice and packet data, providing a unified target network for multimedia services and applications. [0003] IMS uses the IP packet domain as the bearer channel for its control signaling and media transmission, and uses the Session Initiation Protocol (SIP) as the call control signaling to realize the separation of service management, session control and bearer access. [0004] The SIP protocol is an application layer control protocol for establishing, changing and terminating multimedia sessions or calls. Thes...
