Description
Technical Field

Background
Network Function Virtualization (NFV), a concept of Network architecture (Network architecture), refers to a concept that a Network node level function is divided into several functional blocks by using a Virtualization technology, and the functional blocks are respectively implemented in a software manner and are not limited to a hardware architecture.
At the heart 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 core, ornamentation, security, policy, etc., but virtualizing the network function requires the integration of applications, business processes, and infrastructure software that can be integrated and coordinated.
The goal of NFV is to provide network functionality on a standard server, rather than on a custom device. Although both vendors and network operators are eagerly at deploying NFV, early NFV deployments would have to take advantage of broader principles that would gradually be deployed as more detailed information surfaced.
The Session Initiation Protocol (SIP message processing system) is an application-layer signaling control Protocol for creating, modifying and releasing sessions of one or more participants. These sessions can 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.

Detailed Description
The embodiment of the invention provides 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 solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. 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.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related 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, where an execution subject of the method may be a SIP message processing system, which may also be referred to as a SIP message distribution system, and the SIP message processing system is deployed in a server of an NFV network architecture. The method may specifically comprise the steps of:
step S101, receiving a first SIP message sent by a message entry network element, wherein the first SIP message carries 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, sending a second SIP message to the first target service application according to the address of the first target service application, where 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.
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 as CSCF); the message entry network element will establish communication with the first target application via a first SIP message.
Specifically, the first SIP message may be an invite message in an SIP protocol, where the invite message carries number information of a message entry network element, and after receiving the invite message, the SIP message processing system 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 a calling number or a called number, and the application is not limited thereto.
In step S102, the SIP message processing system extracts the number information carried in 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 obtains 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 indicate that the first target service application establishes 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 packet and sub-packet processing is performed on the ip packet in the transport layer of the first SIP message, and when the ip packet is assembled, the ip and port (port) information of the last node (of the message entry network element) is filled in 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 receiving the first SIP message sent by the SIP message processing system, the first target service application may extract a via field in the first SIP message according to the SIP message processing system protocol, where the via field carries address information of the message entry network element, and since the SIP message processing system does not change the via field, the target service application may consider the via field as a message sent from the message entry network element in the SIP message processing system. Specifically, the socket in the java language network packet cannot realize ip forgery, so that the native socket of the c language can be used for realizing ip forgery, and then the jni technology is used for calling the library, so that the ip forgery is realized in the java environment. Because the original socket is adopted in the message distribution system of the SIP message processing system to disguise the ip packet, the ip address and the port in the ip packet are also the ip packet and the port of the message inlet, the ip and the port extracted from the udp packet in the target service application are still the ip address and the port of the message inlet network element.
The first target service application establishes SIP message processing system session with the message entrance network element, when response message is needed, no address trace of the SIP message processing system exists at all, and the system is not sensitive, so the response message can be directly sent to the message entrance network element, and simultaneously, a complete path recordreute is recorded according to the SIP message processing system protocol; the request message sent by the subsequent message entry network element is addressed according to the recordreute, and the message does not pass through the message processing system in the subsequent signaling of the session.
According to the technical scheme provided by the embodiment of the invention, the SIP message processing system hides the address information of the SIP message processing system and disguises the address information as the address of the message inlet network element, so that the system is not influenced and has zero intrusion, and meanwhile, the service processing system is not aware, thereby realizing the message communication of the SIP message processing system under the NFV architecture.
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 know the message processing pressure of the current target service application pair in time. When more subsequent signaling or less feedback time is required, the processing pressure of the target service application is higher, and the target service application cannot be processed in time.
Therefore, 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 a parameter a, and the parameter a represents the total duration of N messages sent to the first target service application by the message entry network element; and receiving a second feedback message sent by the first target service application, wherein the second feedback message carries a parameter b, the parameter b represents the total duration of the target service application responding to the N messages, and N is a positive integer.
It should be understood that N may be a preset value such as 100, 200, etc., and 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 inlet network element continues to communicate with the first target service application or not according to the parameter a and the parameter b.
Specifically, the first feedback message and the second feedback message may both be selection messages (which may also be referred to as heartbeat messages) in the SIP protocol, where a parameter a represents a total duration of sending N messages to the target service application by the message entry network element, and a parameter b represents a total duration of responding to the N messages by the target service application. For example, when N is 100, the target service application performs feedback to the SIP message processing system once after sending 100 pieces of SIP message processing system information (such as 100 th, 200 th, 300 th, and the like), and sends a parameter a through a first feedback message; and after responding 100 pieces of SIP message processing system information, feeding back to a signaling distribution system of the SIP message processing system once, and sending the parameter b 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 to say, the SIP message processing system determines whether to instruct the message entry network element to continue to communicate with the first target service application according to the pressure of the first target service application processing message, and if the SIP message processing system determines that the pressure of the first target service application is too high, the SIP message processing system instructs the message entry network element to no longer communicate with the first target service application, and then the message entry network element may communicate with the second target service application according to the number information and the 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 high, and the processing state is poor, and at this time, the message entry network element and the target service application should be instructed not to continue communication any more; 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 low, 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, according to the parameter a and the parameter b, whether the message entry network element continues to communicate with the first target service application includes: when delta is larger than or equal to max, stopping replying an option heartbeat response message to the message entry network element, and when the option heartbeat response message is not received in a preset time period of the message entry network element, no communication with the first target application is continued; and when the min is less than or equal to delta, replying an option heartbeat response message to the message entry network element, and the message entry network element continuously communicates 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 an actual application, for example, min may be 1000ms, max may be 1200ms, and the like, and the preset time period may also be set according to an actual application scenario, for example, 10s, and the present application is not limited thereto.
According to the technical scheme provided by the embodiment of the invention, the address information of the SIP message processing system is replaced by the address of the message entrance 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 SIP message processing method and the SIP message processing system can be realized by adopting high-level language compiling, are suitable for all the existing mainstream servers, do not depend on special hardware, meet the idea of compiling once to run everywhere, have the characteristics of strong application type and the like, can meet more requirements through a small amount of customized development, and have very strong robustness.
According to the technical scheme, the shunting scheme can be realized and supported friendly, not only can the message distribution scene of the number level be realized, but also the condition of message processing can be fed back through service application, and the SIP message processing system is indicated to regulate and control the communication of the signaling, so that load balancing is realized, and the processing efficiency is effectively improved.
Fig. 2 shows a schematic flow chart of a method of an embodiment of the present 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 number information of the message entry network element, and after receiving 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.
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 message includes the IP address information and the port information of the message entry network element.
And step S204, the message entrance network element establishes communication with the target service application according to the second invite message.
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 the N messages by the target service application.
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 whether the message entry network element continues to communicate with the target service application according to the parameter a and the parameter b, including: and when delta is larger than or equal to max, stopping responding to the option heartbeat message to the message entry network element, and when the option heartbeat message is not received by the message entry network element, not continuously communicating with the target service application.
And S208, when the min is less than or equal to the delta, continuously responding to the option heartbeat message of the message entry network element, and when the message entry network element receives the option heartbeat message, continuously communicating with the target service application.
