Embodiment 1

[0068] combine image 3The detailed structure schematic diagram of the collaborative fusion access gateway of the present invention further explains the functions and features of each part of the collaborative fusion access gateway.

[0069] The collaborative fusion access gateway of the present invention includes a bottom layer interface management module, a local registration management module, a local session management module, a data sending and receiving module, a SIP signaling management module and an identification mapping management module, specifically as follows:

[0070] (1) The underlying interface management module includes various interfaces directly connected to the local device that meet specific technical specifications, such as WiFi interface, RFID interface, etc. Each interface can transfer the data of the local device to the data transceiver module and local registration management through the internal interface The module forwards data to the local device;...

Embodiment 2

[0077] to combine Figure 4~5 , the registration process of the local device in the present invention, the steps are as follows Figure 4 Shown in ①~④:

[0078] Step ①, the local device is a monitoring device, the local node name is Camera1, and the node ID is serial number 3. After starting up, initiate a registration request to the collaborative fusion access gateway, and the request message carries the node name, node ID, and service capability information .

[0079] In step ②, the collaborative fusion access gateway receives the registration request of the local device Camera1, and starts the following process:

[0080] 21) At first, it is authenticated and authenticated according to the local session policy, and if it is not passed, a failure response is returned directly, and the local device Camera1 is refused to provide services; if it is passed, then go to the execution of the next process 22);

[0081] 22) The cooperative fusion access gateway selects a shared IMP...

Embodiment 3

[0088] to combine Figure 6 , the local device actively initiates an IMS network session process to an external IMS network user, the steps are as follows Figure 6 As shown in ①~⑧:

[0089] Step ①, assuming Figure 6 The local device Camera1 is a video surveillance device that has been successfully registered. The five-element mapping vector generated by the integrated access gateway is as follows: Figure 5 As shown, the local device Camera1 finds an abnormal situation, and then triggers a session request to the collaborative fusion access gateway.

[0090] In step ②, the collaborative fusion access gateway receives the session request from the local device Camera1, decides to initiate an IMS session request to an external IMS user according to the local session control policy, and the cooperative fusion access gateway extracts the local node name Camera1 and the node name of the local device Camera1. Identifier 3, query the corresponding five-element mapping vector store...

Abstract

The invention discloses a method, a system and an access gateway for intercommunication between local equipment and an IMS (IP Multimedia Subsystem) network. The method comprises the steps that an IMS network host identity field is added in the SIP (Session Initiation Protocol); the collaborative fusion access gateway generates IMS network host identities and host names for the local equipment, then a mapping relationship between the IMS network host identities and the host names is registered in a DNS (Domain Name Server) in the IMS network; IMS users inquire to obtain the host identifies of the local equipment and write the host names and the host identities of the local equipment in the host identity field in SIP session requests; and the collaborative fusion access gateway performs addressing for the local equipment according to the host identity field to realize the adaptation and the forwarding of signaling protocols and data protocols between the local equipment and the IMS users. The collaborative fusion access gateway comprises a bottom layer interface management module, a local registration management module, a local session management module, a data transceiver module, an SIP signaling management module and an identity mapping management module. The method, the system and the access gateway for intercommunication between the local equipment and the IMS network have the advantages that the communication between the IMS users and the designated local equipment is realized and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a method, system and access gateway for intercommunication between a local device and an IMS network. Background technique [0002] The Internet Multimedia Subsystem (IMS) is a standard system established by the Third Generation Partnership Project (3GPP) and located above the core network packet switching (PS) domain. The design goal of the IMS network is to be independent of the underlying access mode, enabling users The terminal can enjoy the rich and available multimedia services provided by the IMS network through any underlying bearer network that provides IP access, and can guarantee the service quality required by the user terminal. The IMS network implements the idea of ​​separation of control and bearer, provides a common shared service control layer, makes network convergence and service convergence possible, and enables IMS users to integrate multiple IP-based m...
