Description

Signaling message processing method, device, equipment and medium
Technical Field
The present invention relates to the field of instant voice communication technologies, and in particular, to a method, an apparatus, a device, and a medium for processing a signaling message.
Background
With the popularization of mobile terminals, more and more mobile internet users are available, and all signaling messages of the same call need to be correctly processed in order to adapt to the use scenes of network switching during the call establishment process and the call of the users. VoIP (Voice over Internet Protocol), which is a Voice call technology over the Internet, is one of the technologies. The VoIP network telephone enables a calling party to hear the voice signal through the steps of digitalizing, compressing and coding, encrypting and packaging, transmitting through a network, then decrypting and decoding, and restoring the digital signal into sound. SIP (Session initiation Protocol) is one of the core protocols of VoIP, and is widely used for controlling multimedia communication sessions, such as voice and video calls over IP networks. SIP is used to create, modify, terminate sessions consisting of one or more media streams and can be used for two-or multi-party sessions. In the signaling transmission phase, a TLS protocol (Transport Layer Security, i.e. secure Transport protocol) is used for protection, i.e. the SIP protocol works on a long connection channel established by the TLS protocol.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
When the prior art maintains a long connection state of a user, one way is to share the state: the data is persisted to a database, and the shared database is accessed among members, but the design is complex, the interaction times are more, the delay is high, the cost is higher in the actual implementation process, the development difficulty is high, and the reliability of the system is not high; another way is to use a long connection server to use a fixed IP or domain name to ensure that the long connection of the user is connected to the same server every time, so that more IP or domain name resources are needed, and the client needs to be modified and is more complex. Therefore, the embodiment of the application discloses a method, a device, equipment and a medium for processing signaling messages, which can forward all signaling messages sent by a client to the same server for processing without depending on middleware such as a database, a distributed cache and the like, so as to reduce the cost and improve the reliability of a system.
The system framework adopted by the present application may specifically refer to fig. 1, and may specifically include: the system comprises a VoIP client 01, an external network intervening firewall 02, an LVS load balancer 03 and a VoIP server 04. The VoIP client 01 comprises a calling client and a called client, the LVS load balancer 03 can support VoIP, and the VoIP server 04 is used for executing and acquiring SIP signaling messages sent by the clients and detecting whether the SIP signaling messages carry address identifiers used for representing target servers; 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 can add the address identifier to the SIP signaling message; and acquiring 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 as to process the SIP signaling message through the target server.
Referring to fig. 2, an embodiment of the present application discloses a signaling message processing method, where the method includes:
step S11: the method comprises the steps of obtaining SIP signaling messages sent by a client side, and detecting whether the SIP signaling messages carry address identifiers used for representing target servers.
In this embodiment, a current VoIP server in a server cluster acquires an SIP signaling message sent by an acquisition client, and detects whether the SIP signaling message carries an address identifier for representing a target server, where the client is specifically a VoIP user client.
Step S12: 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;
in this embodiment, if the SIP signaling message does not carry the address identifier for characterizing the target server, the address identifier of the target server is calculated based on the SIP signaling message, and a response message including the address identifier is replied or sent to the client, so that the client receives the response message and adds the address identifier to a subsequent SIP signaling message.
In another specific embodiment, after detecting whether the SIP signaling message carries an address identifier for characterizing a target server, the method further includes: if so, forwarding the SIP signaling message to the target server according to the address identifier so as to process the SIP signaling message through the target server. That is, if the SIP signaling message carries the address identifier for characterizing the target server, the SIP signaling message is directly forwarded to the target server, so that the SIP signaling message is processed by the target server.
It should be noted that, after calculating the address identifier based on the SIP signaling message, the method further includes: detecting whether a target server corresponding to the address identifier is in a downtime state or an overload state; if yes, the servers which are not in the downtime state and the overload state are screened out from the server cluster to serve as the new target servers. It can be understood that, after the address identifier is calculated, it is necessary to detect whether the target server corresponding to the address identifier is in a down state or an overload state, that is, it is necessary to ensure that the target server can normally operate, and if the target server is in the down state or the overload state, it indicates that the target server cannot normally operate, it is necessary to screen out a server that is not in the down state or the overload state from the server cluster as a new target server. When selecting a new target server, the selection may be performed randomly or according to a certain rule, for example, the selection may be performed sequentially according to the number of the server.
Step S13: and acquiring the SIP signaling message carrying the address identifier, extracting the address identifier from the SIP signaling message, and forwarding the SIP signaling message to the target server according to the address identifier so as to process the SIP signaling message through the target server.
In this embodiment, after the SIP signaling message carries the address identifier, 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 will be appreciated that in one embodiment, if the current VoIP server is the target server corresponding to the address identifier, then no further forwarding is necessary.
Therefore, the method and the device for detecting the address of the target server acquire the SIP signaling message sent by the client and detect whether the SIP signaling message carries the address identification for representing the target server or not; 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 can add the address identifier to the SIP signaling message; and acquiring the SIP signaling message carrying the address identifier, extracting the address identifier from the SIP signaling message, and forwarding the SIP signaling message to the target server according to the address identifier so as to process the SIP signaling message through the target server. Therefore, according to the method and the device, after the SIP signaling message sent by the client is obtained, whether the SIP signaling message carries the address identifier for representing the target server is detected, 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. Therefore, all signaling messages sent by the client can be forwarded to the same server for processing without depending on middleware such as a database, a distributed cache and the like, so that the cost is reduced and the reliability of the system is improved.
Referring to fig. 3 and fig. 4, the embodiment of the present application discloses a specific signaling message processing method, and compared with the previous embodiment, the embodiment further describes and optimizes the technical solution. The method specifically comprises the following steps:
step S21: and acquiring a calling SIP signaling message sent by the calling client and a called SIP signaling message sent by the called client.
In this embodiment, a calling SIP signaling message sent by a calling client and a called SIP signaling message sent by a called client need to be obtained, where it is noted that a user client initiating a VoIP call is the calling client, a user client receiving the VoIP call is the called client, that is, a user who makes a call is the calling client, and a user who receives the call is the called client.
Step S22: and detecting whether the calling SIP signaling message and the called SIP signaling message carry address identifiers used for representing target servers.
In this embodiment, whether the address identifier used for characterizing the target server is carried in the calling SIP signaling message and the called SIP signaling message is detected respectively. Specifically, whether the To-tag parameter in the calling SIP signaling message contains the address identifier of the target server or not and whether the From-tag parameter in the called SIP signaling message contains the address identifier of the target server or not are detected.
Step S23: if the address identifier of the target server is not carried in the calling SIP signaling message and the called SIP signaling message, calculating the address identifier based on the SIP signaling message.
In this embodiment, if neither the calling SIP signaling message nor the called SIP signaling message carries the address identifier of the destination server, the address identifier is calculated based on the SIP signaling message, and correspondingly, if any one of the calling SIP signaling message or the called SIP signaling message carries the address identifier of the destination server, the SIP signaling message is forwarded to the destination server according to the address identifier.
The calculating the address identifier based on the SIP signaling message includes: and acquiring a calling client identifier and a called client identifier in the SIP signaling message, and calculating the address identifier by utilizing a Hash algorithm based on the calling user identifier and the called user identifier. It can be understood that, in this embodiment, the address identifier is calculated by using a hash algorithm, specifically, to obtain the calling client identifier and the called client identifier in the SIP signaling message, where the identifier may specifically be a user ID, then a smaller ID value of the user IDs corresponding to the calling client and the called client is selected, and the hash algorithm is used to perform processing to obtain an index (index) value, and a server corresponding to the index value is used as a target server to obtain the address identifier of the target server, specifically, an IP address.
Step S24: sending a response message including the address identifier to the client so that the client adds the address identifier to the SIP signaling message.
In this embodiment, the sending the response message including the address identifier to the client may specifically include: acquiring a To message header in the calling SIP signaling message, adding the address identifier into a tag parameter of the To message header To obtain first response information, and then sending the first response information To the host exchange client; and acquiring a From message header in the called SIP signaling message, adding the address identifier into a tag parameter of the From message header to obtain second response information, and then sending the second response information to the called client. It will be appreciated that the address identifier needs To be encoded into the tag parameter of the To header in the originating SIP signaling message and the tag parameter of the From header in the terminating SIP signaling message, and that the SIP protocol specifies that the client must carry the tag parameter in the message, so that the server checks the tag parameter in the header To forward the message To the destination server. Fig. 5 is a schematic diagram of replying a response message To a calling client according To the present disclosure, and an italic part in fig. 5 is an address identifier of a target server added To a tag parameter of a To message header in a calling SIP signaling message.
Step S25: and acquiring the SIP signaling message carrying the address identifier, detecting a tag parameter in the SIP signaling message, extracting the address identifier from the tag parameter, and forwarding the SIP signaling message to the target server according to the address identifier so as to process the SIP signaling message through the target server.
In this embodiment, since the SIP signaling message carries the tag parameter and the address identifier is added to the tag parameter, the SIP signaling message can be forwarded to the target server according to the address identifier by detecting the tag parameter in the SIP signaling message and extracting the address identifier from the tag parameter.
Therefore, the address of the target server can be coded into the corresponding tag parameter in the SIP signaling message on the premise of meeting the standard and ensuring the compatibility. Then when processing the subsequent SIP signaling message, extracting the corresponding address identifier from the tag parameter of the SIP signaling message, and forwarding the SIP signaling message to the target server. Therefore, all signaling messages sent by the client can be forwarded to the same server for processing without depending on middleware such as a database, a distributed cache and the like, so that the cost is reduced, the reliability of the system is improved, the delay is low, and the performance is good.
Referring to fig. 6, an embodiment of the present application discloses a signaling message processing apparatus, including:
the identification detection module 11 is configured to acquire an SIP signaling message sent by a client, and detect whether the SIP signaling message carries an address identification for representing a target server;
an identifier calculating module 12, configured to calculate the address identifier based on the SIP signaling message if the SIP signaling message is not received, 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;
a message forwarding module 13, configured to acquire the SIP signaling message carrying the address identifier, extract the address identifier from the SIP signaling message, and forward the SIP signaling message to the target server according to the address identifier, so as to process the SIP signaling message through the target server.
Therefore, the method and the device for detecting the SIP signaling message have the advantages that the SIP signaling message sent by the client is obtained, and whether the SIP signaling message carries an address identifier used for representing a target server or not is detected; 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 can add the address identifier to the SIP signaling message; and acquiring the SIP signaling message carrying the address identifier, extracting the address identifier from the SIP signaling message, and forwarding the SIP signaling message to the target server according to the address identifier so as to process the SIP signaling message through the target server. Therefore, after the SIP signaling message sent by the client is obtained, whether the SIP signaling message carries the address identifier for representing the target server is detected, 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. Therefore, all signaling messages sent by the client can be forwarded to the same server for processing without depending on middleware such as a database, a distributed cache and the like, so that the cost is reduced and the reliability of the system is improved.
