Description

Technical Field

[0001] The present invention relates to the technical field of instant voice communication, and particularly relates to a signaling message processing method, device, equipment and medium. Background Art

[0002] With the popularization of mobile terminals, there are more and more mobile Internet users. In order to adapt to the usage scenarios of network switching during call establishment and in - call, it is necessary to correctly process all signaling messages of the same call. VoIP (Voice over Internet Protocol, that is, voice transmission based on IP) is a voice call technology via the Internet. VoIP network phones process voice signals through digital processing, compression encoding, encryption and packaging, transmission through the network, then decryption and decoding, and restore the digital signals into sound so that the other party of the call can hear. SIP (Session Initialization Protocol, that is, Session Initial Protocol) is one of the core protocols of VoIP and is widely used in controlling multimedia communication sessions, such as voice and video calls on the IP network. SIP is used to create, modify, and terminate sessions composed of one or more media streams, and can be used for two - party or multi - party sessions. In the signaling transmission stage, the TLS protocol (Transport Layer Security, that is, Secure Transport Protocol) is used for protection, that is, the SIP protocol works on the long - connection channel established by the TLS protocol.

[0003] When maintaining the long - connection state of users in the prior art, one approach is state sharing: persist to the database, and members access the shared database. However, the design is relatively complex, the number of interactions is large, the latency is high, the cost is high in the actual implementation process, the development difficulty is great, and the reliability of the system is not high; another approach is to use a long - connection server with a fixed IP or domain name to ensure that the long - connection of the user is connected to the same server each time. Therefore, more IP or domain name resources are required, and the client also needs to be modified, which is relatively complex.

[0004] In summary, how to forward all signaling messages sent by the client to the same server for processing without relying on middleware such as databases and distributed caches to reduce costs and improve the reliability of the system is a problem to be solved at present. Summary of the Invention

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] When maintaining the long connection state of users in the prior art, one approach is state sharing: persisting to a database and members accessing the shared database. However, the design is relatively complex, with a large number of interactions and high latency. In the actual implementation process, the cost is relatively high, the development difficulty is large, and the reliability of the system is not high. Another approach is to use a long connection server with a fixed IP or domain name to ensure that the long connection of the user is connected to the same server each time. Therefore, a large number of IP or domain name resources need to be used, and the client also needs to be modified, which is relatively complex. For this reason, the embodiments of the present application disclose a signaling message processing method, device, equipment, and medium, which can forward all signaling messages sent by the client to the same server for processing without relying on middleware such as databases and distributed caches, so as to reduce costs and improve the reliability of the system.

[0046] The system framework adopted in this application can be specifically referred to Figure 1As shown in the figure, it may specifically include: a VoIP client 01, an external network access firewall 02, an LVS load balancer 03, and a VoIP server 04. Among them, the VoIP client 01 includes a calling client and a called client. The LVS load balancer 03 can support VoIP. The VoIP server 04 is used to execute the steps of obtaining the SIP signaling message sent by the client, and detecting whether the address identifier for representing the target server is carried in the SIP signaling message; if not, calculating the address identifier based on the SIP signaling message, and sending a response message including the address identifier to the client, so that the client adds the address identifier to the SIP signaling message; obtaining the SIP signaling message carrying the address identifier, extracting the address identifier from the SIP signaling message, and then forwarding the SIP signaling message to the target server according to the address identifier, so that the target server processes the SIP signaling message.

[0047] See Figure 2 As shown in the figure, an embodiment of the present application discloses a signaling message processing method, and the method includes:

[0048] Step S11: Obtain the SIP signaling message sent by the client, and detect whether the address identifier for representing the target server is carried in the SIP signaling message.

[0049] In this embodiment, the current VoIP server in the server cluster obtains the SIP signaling message sent by the client, and detects whether the address identifier for representing the target server is carried in the SIP signaling message. The above client is specifically a VoIP user client.

[0050] Step S12: If not, calculate the address identifier based on the SIP signaling message, and send a response message including the address identifier to the client, so that the client adds the address identifier to the SIP signaling message;

[0051] In this embodiment, if the address identifier for representing the target server is not carried in the SIP signaling message, calculate the address identifier of the target server based on the SIP signaling message, and reply or send a response message including the address identifier to the client, so that the client receives the response message and adds the address identifier to the subsequent SIP signaling message.

[0052] In another specific embodiment, after detecting whether the address identifier for characterizing the target server is carried in the SIP signaling message, the following steps are further included: If so, forward the SIP signaling message to the target server according to the address identifier, so that the target server processes the SIP signaling message. That is, if the address identifier for characterizing the target server is carried in the SIP signaling message, directly forward the SIP signaling message to the target server, so that the target server processes the SIP signaling message.

[0053] It should be noted that after calculating the address identifier based on the SIP signaling message, the following steps are further included: Detect whether the target server corresponding to the address identifier is in a down state or an overloaded state; If so, screen out the servers in the server cluster that are not in the down state and the overloaded state as the new target server. It can be understood that after calculating the address identifier, it is necessary to detect whether the target server corresponding to the address identifier is in a down state or an overloaded state, that is, it is necessary to ensure that the target server can work and run normally. If the target server is in a down state or an overloaded state, it means that the target server cannot work and run normally. Then, it is necessary to screen out the servers in the server cluster that are not in the down state and the overloaded state as the new target server. When selecting a new target server, it can be randomly selected or screened according to certain rules. For example, it can be screened in sequence according to the server numbers, etc.

[0054] Step S13: Obtain the SIP signaling message carrying the address identifier, extract the address identifier from the SIP signaling message, and then forward the SIP signaling message to the target server according to the address identifier, so that the target server processes the SIP signaling message.

[0055] In this embodiment, when the address identifier is carried in the SIP signaling message, the address identifier is extracted, and the SIP signaling message is forwarded to the target server corresponding to the address identifier, so that the target server processes the SIP signaling message. It can be understood that in a specific embodiment, if the current VoIP server is the target server corresponding to the address identifier, then there is no need to forward it anymore.

[0056] It can be seen that this application obtains the SIP signaling message sent by the client and detects whether the address identifier for characterizing the target server is carried in the SIP signaling message; if not, the address identifier is calculated based on the SIP signaling message, and an acknowledgment message including the address identifier is sent to the client so that the client adds the address identifier to the SIP signaling message; the SIP signaling message carrying the address identifier is obtained, the address identifier is extracted from the SIP signaling message, and then the SIP signaling message is forwarded to the target server according to the address identifier so that the target server processes the SIP signaling message. Thus, it can be seen that after this application obtains the SIP signaling message sent by the client, it detects whether the address identifier for characterizing the target server is carried in the SIP signaling message. If not, the corresponding address identifier is calculated and added to the SIP signaling message so that when the SIP signaling message is obtained later, the address identifier carried in the SIP signaling message is extracted, and the SIP signaling message is forwarded to the target server based on this address identifier. In this way, without relying on middleware such as databases and distributed caches, all signaling messages sent by the client can be forwarded to the same server for processing, reducing costs and improving the reliability of the system.

[0057] See Figure 3 and Figure 4 As shown, an embodiment of this application discloses a specific signaling message processing method. Compared with the previous embodiment, this embodiment further describes and optimizes the technical solution. Specifically, it includes:

[0058] Step S21: Obtain the calling SIP signaling message sent by the calling client and the called SIP signaling message sent by the called client.

[0059] In this embodiment, it is necessary to obtain the calling SIP signaling message sent by the calling client and the called SIP signaling message sent by the called client. It should be noted that the user client initiating the VoIP call is the calling client, and the user client receiving the VoIP call is the called client, that is, the one making the call is the calling party, and the one answering the call is the called party.

[0060] Step S22: Detect whether the address identifier for characterizing the target server is carried in the calling SIP signaling message and the called SIP signaling message.

[0061] In this embodiment, it is respectively detected whether the address identifier for characterizing the target server is carried in the calling SIP signaling message and the called SIP signaling message. Specifically, it is to detect whether the address identifier of the target server is included in the To-tag parameter of the calling SIP signaling message and whether the address identifier of the target server is included in the From-tag parameter of the called SIP signaling message.

[0062] Step S23: If the address identifier of the target server is not carried in both the calling SIP signaling message and the called SIP signaling message, calculate the address identifier based on the SIP signaling message.

[0063] In this embodiment, if the address identifier of the target server is not carried in both the calling SIP signaling message and the called SIP signaling message, calculate the address identifier based on the SIP signaling message. Correspondingly, if the address identifier of the target server is carried in either the calling SIP signaling message or the called SIP signaling message, forward the SIP signaling message to the target server according to the address identifier.

[0064] The calculating the address identifier based on the SIP signaling message includes: obtaining the calling client identifier and the called client identifier in the SIP signaling message, and calculating the address identifier based on the calling user identifier and the called user identifier by using the hash algorithm. It can be understood that in this embodiment, the address identifier is calculated by using the hash algorithm. Specifically, obtain the calling client identifier and the called client identifier in the SIP signaling message. This identifier can specifically be the user ID. Then select the smaller ID value among the user IDs corresponding to the calling client and the called client, and perform processing by using the hash algorithm to obtain the index value. Use the server corresponding to the index value as the target server, and obtain the address identifier of this target server, which can specifically be the IP address.

[0065] Step S24: Send a response message including the address identifier to the client, so that the client adds the address identifier to the SIP signaling message.

[0066] In this embodiment, the sending a response message including the address identifier to the client specifically may include: obtaining the To header in the calling SIP signaling message, and adding the address identifier to the tag parameter of the To header to obtain the first response information, and then sending the first response information to the calling client; obtaining the From header in the called SIP signaling message, and adding the address identifier to the tag parameter of the From header to obtain the second response information, and then sending the second response information to the called client. It can be understood that it is necessary to encode the address identifier into the tag parameter of the To header in the calling SIP signaling message and the tag parameter of the From header in the called SIP signaling message. And the SIP protocol stipulates that the client must carry the tag parameter in the message. Therefore, the server checks the tag parameter in the message header and can forward the message to the target server. Figure 5 It is a schematic diagram of a response message replied to the calling client disclosed in this application.Figure 5 The italic part is to add the address identifier of the target server to the tag parameter in the To header of the calling SIP signaling message.

[0067] Step S25: Obtain the SIP signaling message carrying the address identifier, detect the tag parameter in the SIP signaling message, extract the address identifier from the tag parameter, and then forward the SIP signaling message to the target server according to the address identifier, so that the target server processes the SIP signaling message.

[0068] In this embodiment, since the SIP signaling message carries a tag parameter and the address identifier has been added to the tag parameter, by detecting the tag parameter in the SIP signaling message and extracting the address identifier from the tag parameter, the SIP signaling message can be forwarded to the target server according to the address identifier.

[0069] It can be seen that the embodiment of the present application can encode the address of the target server into the corresponding tag parameter in the SIP signaling message on the premise of meeting the standards and ensuring compatibility. Then when processing subsequent SIP signaling messages, by extracting the corresponding address identifier from the tag parameter of the SIP signaling message, the SIP signaling message can be forwarded to the target server. In this way, all signaling messages sent by the client can be forwarded to the same server for processing without relying on middleware such as databases and distributed caches, reducing costs, improving the reliability of the system, having low latency, and good performance.

[0070] See Figure 6 As shown, the embodiment of the present application discloses a signaling message processing device, which includes:

[0071] An identifier detection module 11, configured to obtain a SIP signaling message sent by a client and detect whether the SIP signaling message carries an address identifier for characterizing a target server;

[0072] An identifier calculation module 12, configured to, if not, calculate the address identifier based on the SIP signaling message and send a response message including the address identifier to the client, so that the client adds the address identifier to the SIP signaling message;

[0073] A message forwarding module 13, configured to obtain the SIP signaling message carrying the address identifier, extract the address identifier from the SIP signaling message, and then forward the SIP signaling message to the target server according to the address identifier, so that the target server processes the SIP signaling message.

[0074] It can be seen that this application obtains the SIP signaling message sent by the client and detects whether the address identifier for characterizing the target server is carried in the SIP signaling message; if not, the address identifier is calculated based on the SIP signaling message, and an acknowledgment message including the address identifier is sent to the client so that the client adds the address identifier to the SIP signaling message; the SIP signaling message carrying the address identifier is obtained, the address identifier is extracted from the SIP signaling message, and then the SIP signaling message is forwarded to the target server according to the address identifier so that the target server processes the SIP signaling message. Thus, it can be seen that after this application obtains the SIP signaling message sent by the client, it detects whether the address identifier for characterizing the target server is carried in the SIP signaling message. If not, the corresponding address identifier is calculated and added to the SIP signaling message so that when the SIP signaling message is obtained subsequently, the address identifier carried in the SIP signaling message is extracted, and the SIP signaling message is forwarded to the target server based on the address identifier. In this way, without relying on middleware such as databases and distributed caches, all signaling messages sent by the client can be forwarded to the same server for processing, thereby reducing costs and improving the reliability of the system.
