Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method and a system for processing a session initiation protocol SIP message.
Background
Network function virtualization (Network Functions Virtualization, abbreviated as NFV), a concept of network architecture (network architecture, english), refers to dividing a function of a network node hierarchy into several functional blocks by using a virtualization technology, and is implemented in a software manner, and is not limited to a hardware architecture.
The core of NFV is a virtual network function that provides network functions that can only be found in hardware, including many applications such as routing, mobile cores, ornaments, security, policies, etc., but virtualized network functions require a combination of applications, business processes, and infrastructure software that can be integrated and tuned.
The goal of NFV is to provide network functionality on standard servers, rather than on custom devices. While both suppliers and network operators are striving to deploy NFV, early NFV deployments will have to take advantage of broader principles that will be deployed gradually as more detailed information emerges from the surface.
Session initiation protocol (english: session Initiation Protocol, abbreviated: SIP message processing system) is an application-layer signaling control protocol for creating, modifying and releasing sessions for one or more participants. These sessions may be Internet multimedia conferences, IP telephony or multimedia distribution, but the current distribution and processing methods of SIP message processing system messages are not applicable to the current NFV network architecture.
Therefore, there is a need for a method for processing SIP message processing system messages based on NFV network architecture.

Detailed Description
The embodiment of the application provides a Session Initiation Protocol (SIP) message processing method and a processing system thereof.
In order to make the technical solution of the present application better understood by those skilled in the art, the technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, shall fall within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
As shown in fig. 1, an embodiment of the present application provides a session initiation protocol SIP message processing method, where an execution body of the method may be a SIP message processing system, which may also be referred to as a SIP message distribution system, where the SIP message processing system is deployed in a server of an NFV network architecture. The method specifically comprises the following steps:
step S101, a first SIP message sent by a message entry network element is received, wherein the first SIP message carries the number information of the message entry network element;
step S102, according to the number information, determining the address of the first target service application indicated by the first SIP message;
step S103, according to the address of the first target service application, a second SIP message is sent to the first target service application, wherein 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 for indicating 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 a network element that sends the first SIP message, and may be, for example, 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 via the first SIP message.
Specifically, the first SIP message may be an invite message in the SIP protocol, where the invite message carries number information of a network element of the message entry, and after the SIP message processing system receives the invite message, it is considered 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 a calling number or a called number, which is not limited by the present application.
In step S102, the SIP message processing system extracts the number information carried by the first SIP message, and obtains the address of the first target service application associated with the number information from the database, that is, 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 address information of the message entry network element, where 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, the ip packet is encapsulated and packetized at the transport layer of the first SIP message, and when the ip packet is assembled, the ip and port (port) information of the previous node (of the message entry network element) is filled in, so as to disguise the ip and port to which the SIP message processing system belongs, 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, the via field in the first SIP message is extracted according to the SIP message processing system protocol, where the via field carries the address information of the message entry network element, and since the SIP message processing system does not make any modification to the via field, the target service application considers that the message is a message sent from the message entry network element from the SIP message processing system level. Specifically, the socket in the java language network packet cannot realize ip counterfeiting, so that the native socket in the c language can be used for realizing ip counterfeiting, and then the library is called by using the jni technology, so that the ip counterfeiting is realized in the java environment. Because the original socket is adopted to disguise the ip packet in the SIP message processing system message distribution system, the ip address and port in the ip packet are also the ip packet and port of the message inlet, so that the ip and port extracted from the udp packet in the target service application are still the ip address and port of the message inlet network element.
When a first target service application establishes a session of an SIP message processing system with a message entry network element and needs to respond to a response message, no address trace of the SIP message processing system exists at all, and the system is not sensitive, so that the response message is directly sent to the message entry network element, and meanwhile, a complete path recordroute is recorded according to an SIP message processing system protocol; the request message sent by the subsequent message entry network element will be addressed according to the recordsetup, and the message will not pass through the message handling system in the subsequent signaling of the session.
The technical scheme provided by the embodiment of the application can be seen that the SIP message processing system conceals the address information of the SIP message processing system and disguises the address of the message entry network element, thereby having no influence on the system and zero invasion, and simultaneously enabling the service processing system not to perceive, so that the message communication of the SIP message processing system under the NFV architecture is realized.
Because the signaling message interacted between the subsequent message entry network element and the target service application does not pass through the SIP message processing system any more, the SIP message processing system cannot timely know the message processing pressure of the current target service application pair. When the subsequent signaling is more or the required feedback time is less, the processing pressure of the target service application is higher, so that the target service application cannot be processed in time.
Accordingly, to solve the above-mentioned problems, 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 a parameter a, and the parameter a represents the total duration of N messages sent by the message entry network element to the first target service application; and receiving a second feedback message sent by the first target service application, wherein the second feedback message carries a parameter b, and the parameter b represents the total duration of the response of the target service application to the N messages, wherein N is a positive integer.
It should be understood that N may be a preset value such as 100, 200, etc., which is not limited by the present 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 processing response capability of the signaling that has been processed by the first target service application.
Optionally, as an embodiment of the present application, the method further includes: and 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.
Specifically, the first feedback message and the second feedback message may be selection option messages (may also be referred to as heartbeat messages) in the SIP protocol, where a parameter a represents a total duration of sending N messages by the message entry network element to the target service application, and b parameter b represents a total duration of the target service application responding to the N messages. For example, when N is 100, after each time the target service application sends 100 pieces of SIP message processing system information (such as the 100 th, 200 th, 300 th, etc.), feedback is performed to the SIP message processing system once, and the parameter a is sent through the first feedback message; after responding to 100 pieces of SIP message processing system information, the SIP message processing system is signaled and distributed to the system for one time, and the parameter b is sent through a second feedback message. Further, the SIP message processing system can determine 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, the SIP message processing system determines, according to the pressure of the first target service application for processing the message, whether to instruct the message entry network element to continue to communicate with the first target service application, if the SIP message processing system determines that the service pressure of the first target service application is too high, the SIP message processing system instructs the message entry network element not to communicate with the first target service application any more, and then the message entry network element may communicate with the second target service application according to the number information and a preset rule. In other words, if the interval time indicated by the parameter a is short and the interval time indicated by the parameter b is long, the current processing pressure of the first target service application is large, the processing state is poor, and the message entry network element should be indicated to not continue to communicate with the target service application; if the time interval indicated by the parameter a is long and the time interval indicated by the parameter b is short, the current processing pressure of the first target service is small, and the message entry network element can be restarted to communicate with the target service.
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: stopping replying the message entry network element with the option heartbeat response message when delta is more than or equal to max, and stopping communication with the first target application when the option heartbeat response message is not received in a preset time period of the message entry network element; and when the min is less than or equal to delta, replying an option heartbeat response message to the message entry network element, wherein the message entry network element continues 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 may be set according to practical applications, for example, min may be 1000ms, max may be 1200ms, etc., and the above-mentioned preset period may also be set according to practical application scenarios, for example, 10s, which is not limited by the present application.
The technical scheme provided by the embodiment of the application can be seen that the address information of the SIP message processing system is replaced by the address of the message entry network element, so that the address of the intermediate SIP message processing system is hidden, the message processing efficiency is improved, and the server performance is improved.
Furthermore, the realization of the method and the processing system for processing the SIP message can be written in a high-level language, is applicable to all the existing mainstream servers, does not depend on proprietary hardware, meets the thought of one-time compiling and running everywhere, has the characteristics of strong application and the like, can meet more requirements by small quantity of customized development, and has very strong robustness.
The technical scheme of the application can realize and support a streaming scheme, not only can realize the message distribution scene of the number level, but also can instruct the SIP message processing system to regulate and control the communication of the signaling through the condition of service application feedback message processing, thereby realizing load balancing and effectively improving the processing efficiency.
Fig. 2 shows a schematic flow chart of a method of one embodiment of the application.
As shown in fig. 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, where the first invite message carries the number information of the message entry network element, and after the SIP message processing system receives the first invite message, the SIP message processing system considers that the content in the first invite message needs to be forwarded.
In step S202, the SIP message processing system queries the database according to the number information, and obtains the address of the target service application associated with the number information from the database, that is, the SIP message processing system obtains the service processing address of the next hop according to the number information.
In step S203, the SIP message processing system forwards the second invite message to the target service application, where the address information carried in the second invite includes the IP address information and port information of the message entry network element.
In step S204, the message entry network element establishes communication with the target service application according to the second invite message.
In step S205, the target service application obtains a parameter a and a parameter b, where the parameter a represents a total duration of sending N messages to the target service application by the message entry network element, and the parameter b represents a total duration of responding to the N messages by the target service application.
In step S206, the target service application sends the parameter a and the parameter b to the SIP message processing system.
Step S207, the SIP message processing system indicates, according to the parameter a and the parameter b, whether the message entry network element continues to communicate with the target service application, including: and enabling delta-sigma b-sigma a to stop responding to the option heartbeat message to the message entry network element when delta is larger than or equal to max, and enabling the message entry network element not to receive the option heartbeat message and not to continue to communicate with the target service application.
And step S208, when the min is less than or equal to delta, continuing 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, continuing to communicate with the target service application.
