Description

Technical Field

[0001] The present invention relates to the field of network communication technology, and in particular to a method, storage medium, device and computer program product for realizing cross-gateway self-switching communication under a soft switching architecture. Background Art

[0002] Private network communication is a safe and reliable communication network built within some industries or units to meet their needs for organizational management, safe production, dispatching and commanding. It generally provides emergency communication, command and dispatch, daily work communication and other services for government and public security, public utilities, industry and commerce, etc.

[0003] Softswitch systems are generally used in large-scale cross-regional and cross-departmental communication networks to achieve communication within a certain region or department within a private network, between regions and departments, and between private networks and public networks. With the extension of softswitch private network services, more and more important private network communication networks are deployed using softswitch architecture, and access gateways are deployed using SIP protocol. As the user capacity in a single region or department increases, while the user access gateway capacity in the industry decreases, multiple access gateways need to be deployed in a single region or department to meet the access needs of users in a single region or department. In addition, most of the access gateways in the industry can achieve self-switching communication between users within the access gateway, but cannot achieve self-switching communication between multiple access gateways in a single region or department when the network of a single region or department is interrupted from the softswitch core network; or deploy another set of switching equipment in a single region or department to achieve self-switching communication between multiple access gateways in a single region or department, but cannot achieve automatic synchronization of user data and service data, and cannot achieve automatic switching of gateway registration servers in the case of 1+1 disaster recovery deployment of the softswitch architecture.

[0004] In summary, when the network of a single area or department is disconnected from the soft switch core network, how to achieve automatic self-switching communication across multiple access gateways within a single area or department is an urgent problem to be solved. Summary of the invention

[0005] In response to the problems existing in the prior art, the present invention provides a method, storage medium, device and computer program product for realizing cross-gateway self-switching communication under a soft switching architecture. Without changing the soft switching network architecture and increasing the complexity of network elements, network construction and operation and maintenance, automatic self-switching communication between multiple access gateways within a single area or department can be realized, thereby enhancing network communication security.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a method for realizing cross-gateway self-switching communication under a soft switching architecture, specifically comprising the following steps:

[0007] Step S1: configure the border session controller under the soft switch architecture to realize the self-switching communication function between a single area and multiple access gateways within the department;

[0008] Step S2: When the calling party initiates a call to the called party in the case of communication interruption, the border session controller authenticates the calling party and the called party;

[0009] Step S3: After authentication is passed, SIP processes the call in a self-switching manner, routes the call according to the called number in the To header field of the INVITE message, and forwards the INVITE message to the called party, thereby realizing cross-gateway self-switching communication between the calling party and the called party.

[0010] Furthermore, the configuration of the border session controller includes: configuring the interface of the border session controller, including: input IP address and working mode; configuring basic functional data of the border session controller, including: signaling agent and media agent.

[0011] Furthermore, the judgment process of communication interruption in step S2 is: under the soft switching architecture, the communication status between the border session controller and the soft switching core network side is determined by the heartbeat mechanism between the border session controller and the soft switching core network side. When the heartbeat response issued by the border session controller times out, the communication between the border session controller and the soft switching core network side is interrupted.

[0012] Furthermore, in step S2, the process in which the border session controller authenticates the calling party and the called party is as follows: the border session controller authenticates the calling party according to the local registration information. If the identity authentication is legal, the calling party authentication is passed; the border session controller determines whether the called party belongs to the jurisdiction of the border session controller according to the local registration information. If so, the called party authentication is passed.

[0013] Furthermore, in step S3, the specific process of SIP processing the call in the self-switching mode is as follows: the border session controller initiates a self-switching call according to the self-switching flag parameter in the Request-URI header field in the INVITE message.

[0014] Furthermore, the present invention also provides a computer-readable storage medium storing a computer program, wherein the computer program enables a computer to execute the method for implementing cross-gateway self-switching communication under the soft switch architecture.

[0015] Furthermore, the present invention also provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the method for realizing cross-gateway self-switching communication under the soft switching architecture is implemented.

[0016] Furthermore, the present invention also provides a computer program product, including a computer program, and when the computer program is executed by a processor, the method for realizing cross-gateway self-switching communication under the soft switching architecture is realized.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the method for realizing cross-gateway self-switching communication under the soft switching architecture of the present invention configures the interface and basic functional data of the border session controller, so that the border session controller has self-switching capability, thereby realizing self-switching communication between the caller and the called party in the case of communication interruption without changing the soft switching network architecture and increasing the complexity of network elements, network construction and operation and maintenance, reducing the service interruption duration and the impact of network interruption on the service; at the same time, the caller and the called party are authenticated by the border session controller, realizing self-switching communication between a single area and across multiple access gateways within a department, and improving the security of communication.

[0020] The technical solution of the present invention is further explained below in conjunction with the accompanying drawings.

[0021] like Figure 1 The present invention is a flow chart of a method for realizing cross-gateway self-switching communication under a soft switch architecture, and the method specifically comprises the following steps:

[0022] Step S1: Under the soft switch architecture, the border session controller is deployed at the network edge to control the SIP session. The border session controller is configured to realize the self-switching communication function between a single area and multiple access gateways within the department, thereby realizing direct communication between the caller and the called party under the soft switch architecture without passing through the relay device, which is particularly suitable for the situation where the communication between the border session controller and the network element on the soft switch core network side is interrupted. Figure 2 The configuration of the border session controller in the present invention includes: configuring the interface of the border session controller, including: input IP address and working mode; configuring the basic functional data of the border session controller, including: signaling agent and media agent, without changing the soft switching network architecture, without increasing network elements, network construction and operation and maintenance complexity, improving the efficiency of self-switching communication, enhancing network security, optimizing resource utilization, realizing self-switching communication between the calling party and the called party in the case of communication interruption, reducing the service interruption time, and reducing the impact of network interruption on the service

[0023] Step S2, under the soft switch architecture, the communication status between the border session controller and the soft switch core network side network element is determined through the heartbeat mechanism between the border session controller and the soft switch core network side. When the heartbeat response sent by the border session controller times out, the communication between the border session controller and the soft switch core network side is interrupted. When the caller initiates a call to the called party under the communication interruption condition, the border session controller authenticates the caller and the called party. Specifically, the border session controller authenticates the caller according to the local registration information, without the need to re-initiate the registration process, simplifying the process. If the identity authentication is legal, the caller authentication is passed; the border session controller determines whether the called party belongs to the jurisdiction of the border session controller according to the local registration information. If so, the called party authentication is passed. By authenticating the caller and the called party, the security of communication can be improved.

[0024] Step S3: After authentication is passed, SIP processes the call in a self-switching manner. Specifically, the border session controller initiates a self-switching call according to the self-switching flag parameter in the Request-URI header field in the INVITE message, and forwards the INVITE message to the called party, thereby realizing cross-gateway self-switching communication between the calling and called parties.

[0025] The method for realizing cross-gateway self-switching communication under the soft switching architecture of the present invention configures the interface and basic functional data of the border session controller, so that the border session controller has the self-switching capability, thereby realizing self-switching communication between the caller and the called party in the case of communication interruption without changing the soft switching network architecture and increasing the complexity of network elements, network construction and operation and maintenance, reducing the service interruption duration and the impact of network interruption on the service; at the same time, the caller and the called party are authenticated by the border session controller, realizing self-switching communication between a single area and across multiple access gateways within a department, and improving the security of communication.
