Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method, a terminal and a system for SIP registration.
Background
A Session Initiation Protocol (SIP) system includes a SIP server and a terminal, where the terminal is, for example, a Voice over Internet Protocol (VoIP) terminal, and the terminal can implement normal services only after registering in the SIP server.
In the actual use process, when a network fault (such as a shutdown of the SIP server, a power failure, and the like) occurs in the SIP system, all the terminals registered in the SIP server are all offline, and after the terminals are offline, the terminals automatically and continuously send registration requests to the SIP server within a preset time period until the registration is successful or the registration requests are stopped being sent overtime. After the network is recovered to normal, the SIP server may receive the registration requests sent by tens of thousands or even hundreds of thousands of terminals at the same time, and the application layer of the SIP server processes the large number of registration requests, and as the processing capability of the application layer of the SIP service is limited, the SIP server may fail.
However, after the terminal is added to the blacklist, the terminal cannot perform normal services, and unless an administrator performs manual intervention, the terminal added to the blacklist cannot recover normal services in a short time, so that user experience is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of an application scenario of an SIP registration method provided by the present invention, please refer to fig. 1, which includes a plurality of terminals 101A to 101N and an SIP server 102 corresponding to each terminal, where the terminals are terminals having a Voice function, such as Voice over Internet Protocol (VoIP) terminals, Optical Network Unit (ONU) terminals, and the like, and the terminals 101A to 101N need to register in the SIP server 102 to implement a normal service, and the terminals 101A to 101N are connected to the SIP server 102 through a wireless Network respectively to implement a normal service; the following describes a SIP registration method, device, and system in detail through specific embodiments.
Fig. 2 is a first flowchart of an SIP registration method provided by the present invention, which is applied to an SIP system including an SIP server and a terminal, where an execution subject of the method is the terminal, and referring to fig. 2, the method may include:
s201, a terminal acquires a communication state between the terminal and an SIP server;
s202, the terminal judges whether the communication state is a normal state;
s203, when the terminal determines that the communication state is a normal state, generating a random time length;
s204, after the terminal experiences the random time length, the terminal sends a registration request message to the SIP server.
In the embodiment of the invention, the communication state between the terminal and the SIP server comprises the communication link state between the terminal and the SIP server and the state of the SIP server, and the communication state between the terminal and the SIP server is divided into a normal state and an abnormal state; if the communication state between the terminal and the SIP server is a normal state, the communication link state between the terminal and the SIP server is a normal state, and the SIP server is also a normal state; if the communication state between the terminal and the SIP server is abnormal, the communication link state between the terminal and the SIP server is abnormal, or the SIP server is abnormal.
In the practical application process, the terminal starts to execute the embodiment shown in fig. 2 under a specific scenario, where the specific scenario may include the following possible scenarios:
one possible scenario is: the terminal determines that the state between the terminal and the SIP server is switched from a connection state to a disconnection state:
in this possible scenario, the terminal may determine that the state between the terminal and the SIP server is switched from the connected state to the disconnected state through the following two possible implementations: one possible implementation is: under the condition that the terminal and the SIP server are in a connected state, the terminal receives a disconnection request sent by the SIP server; another possible implementation: under the condition that the terminal and the SIP server are in a connected state, the terminal periodically detects the state between the terminal and the SIP server, and the terminal detects that the state between the terminal and the SIP server is changed into a disconnected state.
Another possible scenario is: and the terminal receives a registration failure response message sent by the SIP server.
Yet another possible scenario is: the terminal receives a registration overtime message sent by the SIP server, wherein the registration overtime message is used for indicating that a registration request message sent by the terminal to the SIP server is overtime.
It should be noted that the above is only an example of the scene where the terminal is located, and is not limited to the scene where the terminal is located, and in an actual application process, the scene where the terminal is located may also include other types of scenes, which is not specifically limited by the present invention.
The following describes in detail a procedure of registering a terminal in the SIP server.
When the terminal needs to register in the SIP server, the terminal acquires the communication state between the terminal and the SIP server and judges whether the communication state is a normal state, if the communication state is not the normal state, the communication link between the terminal and the SIP server is failed or the SIP server is failed, the terminal continues to acquire the communication state between the terminal and the SIP server and judges the acquired communication state until the acquired communication state is the normal state.
When the terminal determines that the communication state between the terminal and the SIP server is a normal state, a random time period is generated, and for example, the random time period may be 3 seconds, 15 seconds, or the like. After the terminal generates the random time length and experiences the random time length, the terminal sends a registration request message to the SIP server; for example, assuming that the terminal generates a random time length of 10 seconds at 10 o 'clock in 1 month, 1 day and 2015 year, the terminal sends a registration request message to the SIP server after 10 seconds, that is, 10 o' clock in 1 month, 1 day and 2015 year for 10 seconds; and when the terminal receives the registration success response message sent by the SIP server, the terminal successfully registers in the SIP server.
The following describes in detail the SIP registration method shown in the embodiment of fig. 2 by using a specific example with reference to fig. 3.
Fig. 3 is a schematic diagram of a registration process of a terminal in an SIP server according to the present invention, and please refer to fig. 3, where it is assumed that a terminal successfully registered in the SIP server includes a terminal 1-a terminal N, and if the SIP server is powered off, the terminal 1-the terminal N is simultaneously off-line from the SIP server.
After the terminals 1-N are off-line from the SIP server at the same time, the terminals 1-N respectively and periodically detect the communication state with the SIP server, after the SIP server is powered on, the terminals 1-N all determine that the communication state with the SIP server is a normal state, then the terminals-N stop detecting the communication state with the SIP server, and the terminals 1-N respectively generate random time length according to the preset maximum time length, for example, the random time length generated by the terminal 1 is 2 seconds, the random time length generated by the terminal 2 is 6 seconds, the random time length generated by the terminal 3 is 4 seconds, and the random time length generated by the terminal N is 5 seconds; and each terminal sends a registration request message to the SIP server after the generated random time length.
In the SIP registration method provided by the embodiment of the invention, a terminal acquires the communication state between the terminal and an SIP server and judges whether the communication state is normal or not, the terminal sends a registration request message to the SIP server when determining that the communication state is normal, and the SIP server returns a registration success response message to the terminal when receiving the registration request because the communication state between the terminal and the SIP server is normal, so that the terminal can successfully register by sending the registration request message to the SIP server once, further, when sending the registration request message to the SIP server, the terminal generates a random time length according to a preset maximum time length, the random time length is any time length smaller than the preset maximum time length, the terminal sends the registration request message to the SIP server after experiencing the random time length, and the random time lengths generated by different terminals are generally different, therefore, the method and the device avoid that a plurality of terminals send the registration request message to the SIP server at the same time, thereby avoiding that the SIP server receives a large amount of registration request messages at the same time, and further avoiding the SIP server from being in fault in the SIP registration process.
In the embodiment shown in fig. 1, optionally, when determining that the communication state is the normal state, the terminal may generate a random time length according to a preset maximum time length, where the random time length is any time length smaller than the preset maximum time length; the preset maximum duration is a duration preset in the terminal by the user, optionally, the preset maximum duration may be 20 seconds, and the random duration generated according to the preset maximum duration is any duration less than 20 seconds, such as 3 seconds, 15 seconds, and the like. In practical application, the preset maximum duration can be set according to actual needs.
In the embodiment shown in fig. 1, optionally, the terminal may obtain the communication state between the terminal and the SIP server through the following feasible implementation manners:
the terminal sends a detection message to the SIP server, wherein the detection message is used for acquiring the communication state between the terminal and the SIP server; judging whether a feedback message corresponding to a detection message sent by an SIP server is received within a preset time length, if so, determining that the communication state between the terminal and the SIP server is a normal state; and if not, determining that the communication state between the terminal and the SIP server is an abnormal state.
In this feasible implementation manner, the terminal may periodically send the probe message to the SIP server, optionally, the period may be 100 milliseconds, and the length of the period may be set according to actual needs; if the communication state between the terminal and the SIP server is a normal state (a communication link between the terminal and the SIP server is normal, and the SIP server is normal), when a transport layer of the SIP server receives a probe Message, the SIP server sends a feedback Message corresponding to the probe Message to the terminal, therefore, after the terminal sends the probe Message to the SIP server, if the feedback Message corresponding to the probe Message sent by the SIP server is received within a preset time period, it is determined that the communication state between the terminal and the SIP server is a normal state, and if the feedback Message corresponding to the probe Message sent by the SIP server is not received within the preset time period, it is determined that the communication state between the terminal and the SIP server is an abnormal state, optionally, the probe Message may be a Control Message Protocol (ICMP) Message.
The terminal sends the detection message to the SIP server, and when the detection message reaches the transmission layer of the SIP server, the SIP server may generate a corresponding feedback message according to the detection message, and send the feedback message to the terminal, and the detection message does not need to be transmitted to the application layer of the SIP server, and further does not need to be processed by the application layer of the SIP server.

The receiving module 405 may be further configured to determine that the state between the terminal and the SIP server is switched from the connection state to the disconnection state before the obtaining module 401 obtains the communication state between the terminal and the SIP server corresponding to the terminal; or receiving a registration failure response message sent by the SIP server; or receiving a registration timeout message sent by the SIP server, where the registration timeout message is used to indicate that a registration request message sent by the terminal to the SIP service times out.

specifically, the terminal judges whether a second feedback message corresponding to the detection message sent by the standby SIP server is received within a preset time length;
if so, determining that the communication state between the terminal and the standby SIP server is a normal state;
if not, determining that the communication state between the terminal and the standby SIP server is an abnormal state.
Repeating the steps of S901-S906 until the terminal determines that the communication state between the terminal and the main SIP server is an abnormal state and the communication state between the terminal and the standby SIP server is a normal state, and executing S907;
s907, the terminal generates a random time length according to a preset maximum time length;
s908, after the random time length, the terminal sends a second registration request message to the standby SIP server;
s909, the standby SIP server sends a second registration success response message to the terminal within a preset response time;
s910, registration is successful.
In the above SIP registration process, the terminal sends a registration request message to the SIP server when determining that the communication state is normal, because the communication state between the terminal and the SIP server is normal, the SIP server will return a registration success response message to the terminal when receiving the registration request, so that the terminal can successfully register by sending the registration request message to the SIP server once, further, when sending the registration request message to the SIP server, the terminal generates a random time length specifically according to the preset maximum time length, the random time length is any time length less than the preset maximum time length, the terminal sends the registration request message to the SIP server after experiencing the random time length, because the random time lengths generated by different terminals are generally different, the multiple terminals are prevented from sending the registration request message to the SIP server at the same time, thereby preventing the SIP server from receiving a large number of registration request messages at the same time, and further, the SIP server is prevented from being failed in the SIP registration process.
