Detailed ways

Embodiments of the present invention provide a session initiation protocol SIP message processing method and a processing system thereof.

In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

As shown in FIG. 1 , an embodiment of the present invention provides a session initiation protocol SIP message processing method. The execution body of the method may be a SIP message processing system or a SIP message distribution system. The SIP message processing system deploys In the server of the NFV network architecture. The method may specifically include the following steps:

Step S101, receiving a first SIP message sent by a message entry network element, where the first SIP message carries number information of the message entry network element;

Step S102, according to the number information, determine the address of the first target service application indicated by the first SIP message;

Step S103: Send a second SIP message to the first target service application according to the address of the first target service application, wherein the address information carried in the second SIP message is the address of the message entry network element information, the second SIP message is used to instruct the first target service application to establish a session with the message entry network element.

Specifically, in step S101, the message entry network element refers to the network element that sends the first SIP message, such as a call session control function (English: Call Session Control Function, abbreviated: CSCF); the message entry network element will Establish communication with the first target application through the first SIP message.

Specifically, the first SIP message may be an invite message in the SIP protocol, and the invite message carries the number information of the message entry network element. After the SIP message processing system receives the invite message, it considers that the message content of the invite message needs to be forwarded to The first target application.

It should be understood that the number information of the message entry network element may be the calling number or the called number, which is not limited in this application.

In step S102, the SIP message processing system will extract the number information carried in the first SIP message, and obtain the address of the first target service application associated with the number information from the database, that is to say, the SIP message processing system will Obtain the service processing address of the next hop according to the number information.

In step S103, the SIP message processing system sends a second SIP message to the first target service application according to the address of the first target service application.

Specifically, the address information carried in the second SIP message is the address information of the message entry network element, and the second SIP message is used to instruct the first target service application to establish a session with the message entry network element .

Optionally, as an embodiment of the present application, the address information carried in the first SIP message includes IP address information and port information of the message entry network element.

Specifically, at the transport layer of the first SIP message, the ip packet is packaged and sub-packaged, and when the ip packet is assembled, the ip and port information of the previous node (of the message entry network element) are filled in, The ip and port to which the SIP message processing system belongs are disguised, so that the ip and port to which the SIP message processing system belongs do not exist in the network message.

Further, after the first target service application receives the first SIP message sent by the SIP message processing system, it will extract the via field in the first SIP message according to the SIP message processing system protocol, and the via field carries the message entry network element. Since the SIP message processing system does not make any changes to the via field, from the SIP message processing system level, the target service application will think that this is a message sent from the message entry network element. Specifically, the socket in the java language network package cannot implement ip forgery, so you can use the native socket of the c language to realize ip forgery, and then use the jni technology to call the class library to realize ip forgery in the java environment. Since the native socket is used in the message distribution system of the SIP message processing system to disguise the ip package, the ip address and port in the ip package are also the ip package and port of the message entry, so the ip and port extracted from the udp package in the target business application It is still the IP address and port of the message entry network element.

When the first target service application establishes a SIP message processing system session with the message entry network element and needs to respond to a corresponding response message, there is absolutely no trace of the address of the SIP message processing system, and it has no sense of the system. Therefore, the response message will be sent directly. It is sent to the message ingress network element, and the complete path recordroute is recorded according to the SIP message processing system protocol; the request message sent by the subsequent message ingress network element will be addressed according to the recordroute, and the messages in the subsequent signaling of the session will be all addressed. Does not go through the message processing system.

It can be seen from the technical solutions provided by the above embodiments of the present invention that the SIP message processing system hides its own address information and pretends to be the address of the message entry network element, which has no impact on the system, zero intrusion, and at the same time makes the service processing system unaware, thereby realizing The SIP message processing system message communication under the NFV architecture.

Since the signaling messages exchanged between the subsequent message entry network element and the target service application no longer pass through the SIP message processing system, the SIP message processing system cannot timely know the message processing pressure of the current target service application. When there are more subsequent signaling or the required feedback time is less, the processing pressure of the target service application will be high, so that it cannot be processed in time.

Therefore, in order to solve the above problem, optionally, as an embodiment of the present application, the method further includes: receiving a first feedback message sent by the first target service application, wherein the first feedback message carries parameters a, the parameter a represents the total duration of the message entry network element sending N messages to the first target service application; receiving the second feedback message sent by the first target service application, wherein the second The feedback message carries a parameter b, where the parameter b represents the total duration of the target service application responding to the N messages, where N is a positive integer.

It should be understood that N can be a preset value such as 100, 200, etc., which is not limited in this application, the parameter a represents the pressure of the signaling that needs to be processed by the first target service application, and the parameter b represents the signaling that has been processed by the first target service application. processing responsiveness.

Optionally, as an embodiment of the present application, the method further includes: indicating, according to the parameter a and the parameter b, whether the message entry network element continues to communicate with the first target service application.

Specifically, both the first feedback message and the second feedback message may be a selection option message in the SIP protocol (also referred to as a heartbeat message), where parameter a indicates that the message entry network element sends N to the target service application The total duration of the N messages, and the parameter b represents the total duration of the target service application responding to the N messages. For example, when N is 100, after every 100 pieces of SIP message processing system information sent by the target service application (such as the 100th, 200th, 300th, etc.) Send parameter a; after each response to 100 pieces of SIP message processing system information, a feedback is made to the SIP message processing system signaling distribution system, and parameter b is sent through a second feedback message. Further, the SIP message processing system can judge the current pressure of the target service application and the current state of the target service application according to the parameter a and the parameter b.

That is to say, the SIP message processing system will determine whether to instruct the message entry network element to continue communicating with the first target service application according to the pressure of the first target service application to process messages. When the value is large, the message entry network element will be instructed to no longer communicate with the first target service application, then the message entry network element can communicate with the second target service application according to the number information and preset rules. In other words, if the interval indicated by parameter a is short and the interval indicated by parameter b is long, it means that the current processing pressure of the first target service application is high and the processing state is poor, and the message portal network should be indicated at this time. If the time interval indicated by parameter a is long and the time interval indicated by b is short, it means that the current processing pressure of the first target service is low, and the message entry network element and the target service can be reopened to communicate.

Optionally, as an embodiment of the present application, the indicating whether the message entry network element continues to communicate with the first target service application according to the parameter a and the parameter b includes: setting δ=∑b -∑a, when δ≥max, stop replying the option heartbeat response message to the message entry network element. When the message entry network element does not receive the option heartbeat response message within the preset time period, it will no longer communicate with the The first target application continues communication; when min≤δ, returns an option heartbeat response message to the message entry network element, and the message entry network element will continue to communicate with the first target application according to the option heartbeat response message.

It should be understood that the values of min and max can be set according to actual applications, for example, min can be 1000ms, max can be 1200ms, etc. The above preset time period can also be set according to actual application scenarios, such as 10s, which is not set in this application. limited.

It can be seen from the technical solutions provided by the above embodiments of the present invention that the present application hides the address of the intermediate SIP message processing system by replacing the address information of the SIP message processing system with the address of the message entry network element, thereby improving the efficiency of message processing and improving the efficiency of message processing. Server performance.

Further, the implementation of the SIP message processing method and processing system of the present application can be written in a high-level language, applicable to all current mainstream servers, does not depend on proprietary hardware, satisfies the idea of compiling once and running everywhere, and has the characteristics of strong application type, etc. A small amount of customized development can meet more needs and has very strong robustness.

The technical solution of the present application can be friendly to the implementation and support of the offloading solution, not only can realize the scene of message distribution at the number level, but also can feedback the message processing situation through the service application, and instruct the SIP message processing system to carry out the communication of the signaling. Control, so as to achieve load balancing, thereby effectively improving processing efficiency.

As shown in Figure 2, the communication method is applied to a network function virtualization NFV network architecture, and the method includes:

Specifically, in step S201, the message entry unit sends a first invite message to the SIP message processing system, and the first invite message carries the number information of the message entry network element. After the SIP message processing system receives the first invite message, it considers that the The content in the first invite message needs to be forwarded.

Step S202, the SIP message processing system will query the database according to the number information, and obtain the address of the target service application associated with the number information from the database, that is to say, the SIP message processing system will obtain the next hop according to the number information. Business processing address.

Step S203, the SIP message processing system forwards the second invite message to the target service application, and the address information carried in the second invite includes IP address information and port information of the message entry network element.

Step S204, the message entry network element establishes communication with the target service application according to the second invite message.

Step S205, the target service application obtains the parameter a and the parameter b, wherein the parameter a represents the total duration for the message entry network element to send N messages to the target service application, and the parameter b represents that the target service application responds to the The total duration of N messages.

Step S206, the target service application sends parameter a and parameter b to the SIP message processing system.

Step S207, the SIP message processing system indicates whether the message entry network element continues to communicate with the target service application according to the parameter a and the parameter b, including: setting δ=∑b-∑a, when δ≥max When the message entry network element stops responding to the option heartbeat message to the message entry network element, when the message entry network element does not receive the option heartbeat message, it will no longer continue to communicate with the target service application.

Step S208, when min≤δ, continue to respond to the option heartbeat message of the message entry network element, and when the message entry network element receives the option heartbeat message, it will continue to communicate with the target service application.
