Description

Method and service platform for realizing broadband service function under NGN

Technical field

The present invention relates to the field of intelligent network communication under the NGN (Next Generation Network) network, and particularly relates to an implementation method and a service platform for implementing broadband service functions under the NGN. Background technique

The Next Generation Network (NGN), also known as the Next Generation Network, is mainly designed to provide multimedia services in a unified management manner on a unified network platform, integrating existing fixed-line and mobile phones in the city. On the basis of (collectively referred to as FMC (Fixed Mobile Convergence)), multimedia data services and other value-added services are added. The voice exchange will use softswitch technology, and the main implementation of the service platform is IP technology, which gradually realizes unified communication. Among them, VOIP (voice over Internet Protocol) will be the focus of the next generation network. To underscore the importance of IP technology, Cisco Systems, one of the industry's leading companies, claims to be IP-NGN.

NGN is a packet network that provides multiple services including telecommunication services. It can utilize multiple bandwidths and QoS (Quality of Service) capabilities to separate business functions from the underlying transport technology. It allows users to freely access different service provider networks and supports universal mobility to achieve user consistency and uniformity in service usage. It is based on softswitch and provides a comprehensive and open network architecture based on packet technology including voice, data, video and multimedia services, representing the direction of communication network development. NGN has packet transmission, control functions separated from bearer, call/session, application/service, service provision and network separation, providing open interfaces, utilizing basic service components, providing a wide range of services and applications, end-to-end QoS and transparency The transmission capability enables interoperability with traditional networks through open interface specifications, universal mobility, allows users to freely access different service providers, supports multiple signage systems, and integrates fixed and mobile services.

As the core technology of NGN network, the development of softswitch (Softswitch) has received more and more attention. As the control function of next-generation network, softswitch has real-time requirements for NGN. The service provides call control and connection control functions. The definition of softswitch in the Institute of Telecommunications Transmission of the Ministry of Information Industry of China is: Softswitch is one of the core devices of network evolution and next-generation packet network. It is independent of the transport network and is mainly used for call control, resource allocation, protocol processing, The main functions of routing, authentication, billing, etc., can also provide users with all the services that the existing circuit switch can provide, and provide programmability to third parties.

At present, China has completed and promulgated the "General Technical Requirements for Softswitch Equipment" (YDC003-2001), which clearly defines the location, functional requirements, service requirements, operation and maintenance, network management requirements, protocols and interface requirements of softswitches in the network. Billing requirements and performance indicators, and specify interoperability requirements with IP phones and intelligent networks. It is particularly worth mentioning that not only the fixed network, but also the technical requirements for mobile softswitch equipment and the review of equipment specifications have been completed recently, mainly for the characteristics of softswitch technology in mobile network mobility management and authentication. The corresponding extension. It is not difficult to see that softswitch technology plays an important role as the core technology of the network, both in the development and integration of fixed networks and mobile networks, in the context of the increasing popularity of packet switching.

Softswitch technology is distinguished from the most prominent features of other technologies, and the three basic elements of its core ideas are:

1) Open service generation interface

The main way Softswitch provides services is to cooperate with the "application server" through the API (Application Programming Interface) to provide new integrated network services. At the same time, in order to better balance the existing communication network, it can also pass the existing SCP (Service Control Point, Service) in INAP (Intelligent Network Application Protocol) and IN (Intelligent Network). Control points) to provide traditional smart services;

2) Integrated device access capabilities

Softswitch can support a wide range of protocols to control a wide variety of access devices.

3) Policy-based operational support system

Softswitch uses a policy-based approach that is completely different from traditional OAM (Operation Administration and Maintenance) systems. Implementation mode to complete the function of the operation support system, real-time, intelligent, centralized adjustment and intervention of network characteristics according to certain strategies to ensure the stability and reliability of the entire system.

In the current NGN environment, the softswitch provides an API interface to the service application server, and the user name and password for registering the user, SIP (Session Initiation Protocol), user authentication data, and user's IFC. (Initial Filter Criteria, initial filtering rule) triggers rules and other functions. With the triggering rule, the intelligent network service platform can be triggered to implement various functions of the intelligent network service.

Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

As shown in FIG. 1 , in this embodiment, the intelligent network service platform includes: a SIP proxy server.

(SIP Proxy, referred to as SIPPXY), Service Application Server (AS), SIP Application Proxy (SIP-AP) and SIP Route Server (SIPROUTE). among them:

SIPPXY provides functions such as interface with SIP-AP, distribution of third-party registration, etc.

The AS is used to provide the underlying service capabilities, such as: call control and other functions;

SIP-AP is used to complete login management, subscription management, service registration, and SIP message routing. It is used to implement the functions to be implemented by the softswitch in the NGN environment and to perform SIP message processing and forwarding. It needs to complete the login management such as receiving client registration and logout, as well as subscribe to the registration management and notification, and register the AS with the user after the registration is successful. In addition to the function of registration, the SIP message needs to be routed, and the user's subscription service type is forwarded to the corresponding AS to implement various functions of the service;

The SIPROUTE is used to complete the query of the subscription information of the user registered on the SIP-AP, and forwards the SIP message to the corresponding AS through the type of the subscribed service of the queried user. The protocols used between the above network elements are as follows:

SIPPXY and the UE use the mediation of the signaling and the call, and the signaling uses the SIP protocol to communicate with each other, and the media of each other follows the MGCP (Media Gateway Control Protocol) protocol;

R01 internal communication is used between SIPPXY and SIP-AP. The messages exchanged between the two include the IP address of the source sender, the port of the source sender, the link number of the registration request message, the softswitch sequence number, and the SIPPXY receive registration request message. Link address and port, the index of the SIPPXY application registration data area, and the necessary SIP header field information;

The SIP communication between the SIP-AP and the SIPROUTE uses the R01 internal communication. After receiving the SIP message to be forwarded, the SIP-AP sends a message to the SIPROUTE to obtain the routing information. The SIPROUTE returns the routing result after receiving the message request. The SIP-AP returns the result according to the return. Inform SIPPXY to forward the message.

As shown in Figure 2, the registration process for intelligent network users is as follows:

Step 201: The intelligent network broadband user A sends a registration request message (Register) to the SIPPXY. Step 202: SIPPXY retrieves whether the current value is saved by using the Call-ID carried in the registration request message and the Branch field of Via as a hash key (hash key value). The user's information. In the case of no storage, SIPPXY will apply for the data area according to the above HashKey, and then update the above information to the data area, and send a registration request message to the SIP-AP;

Step 203: After receiving the registration request message, the SIP-AP performs an authentication judgment, and after the authentication is passed, constructs a registration response message to the SIPPXY, where the authentication result is carried;

Step 204: SIPPXY sends a registration response message to user A. If the authentication result is successful, the third-party registration request message needs to be sent to the corresponding service platform, so that user A is successfully registered.

As shown in Figure 3, the call flow between broadband users in the intelligent network is as follows:

Step 301: User A initiates a call to User B, sends a call request to SIPPXY, and SIPPXY forwards the call request to the SIP-AP;

Step 302: After receiving the above call request, the SIP-AP sends a message to the SIPROUTE to obtain the ROUTE information and the subscription information of the user A. The SIPROUTE is based on the user A carried therein. The identification information queries the ROUTE information and the subscription information of the user A, and returns the query result to the SIP-AP;

Step 303: The SIP-AP notifies the SIPPXY to forward the call request according to the query result returned by the SIPROUTE. The SIPPXY forwards the call request message to the AS, and the AS triggers the service flow according to the subscription information in the message. After the process of all services is triggered, the SIP-AP forwards the call to User B to implement the call between User A and User B.

As shown in FIG. 4, it is assumed that UE A and UEB are intelligent network broadband users, and a method for implementing an intelligent network service call function in an NGN. The specific registration and call signaling procedures are as follows:

Step 1: UE A sends a registration request message to SIPPXY.

Step 2: The SIPPXY retrieves the information of the UE A according to the Call-ID carried in the registration request message and the Branch field of the Via as the HashKey. In the case of no save, SIPPXY will apply for the data area according to the HashKey, and then update processing (such as saving the source link number, source SS index, source address and port, FromTag, Host part of the top Via header field); The SIP-AP sends a registration request message, which carries: the IP address of the source sender (ie, UE A), the port of the source sender, the link number of the registration request message, the softswitch sequence number, and the link of the SIPPXY receiving the registration request message. Address and port, Selflndex of SIPPXY application registration data area, and necessary SIP header field information, then apply for shared memory to save the registration request message, and set timeout timer Timerl; if the timeout timer expires, it still has not received The registration response message replied by the SIP-AP, the registration request message is deleted from the shared memory;

Step 3: After receiving the registration request message sent by the SIPPXY, the SIP-AP first searches for the user's personal information from the memory according to the identification information of the UE A carried in the message. If the user does not have the personal information in the memory, the corresponding database is accessed. In the middle, the user's registration information and personal information are queried. Step 4: After the database returns the queried information, save the personal information to the memory, and determine whether the CALLID carried in the received registration request message and the registered CALLID in the queried registration information are The same, not the same return 401 response; otherwise the next step is performed;

Steps 5-6: The SIP-AP configuration registration response message is sent to the SIPPXY, and the 401 unauthorized response message is returned. The response message includes the WWW-Authenticate header field. The SIPPXY forwards the 401 unauthorised response message to the UE A. The Authenticate header field is calculated by the SIP-AP according to the nonce and password; the nonce is the character randomly generated and saved by the SIP-AP. String, password is the password information of the queried user;

Steps 7-8: The UE A sends a registration request message to the SIP-AP again according to the WWW authentication information carried in the received unauthorized response message, where the Authorization header field contains the WWW authentication information carried in the unauthorized response message. ;

Step 9~10: After receiving the registration request message containing the Authorization header field, the SIP-AP performs authentication authentication and finds that the Contact header field is missing, so it sends a 403 response to UE A.

Steps 11 to 16: After receiving the 403 response, UE A reconstructs the registration request message, adds a Contact header field based on the registration request message of step 1, and then sends the contact header field to the SIP-AP; SIP-AP returns 401 Unauthorized to UE A. The response message includes the WWW-Authenticate header field. The terminal sends a registration request message to the SIP-AP, which carries the Authorization header field. After receiving the SIP-AP, the SIP-AP uses the saved nonce and the queried password to calculate the Authorization header. If the domain is inconsistent with the Authorization header field sent by UE A, the 403 error is returned. If the contact header field is consistent and the registration header field is included in the registration request message, the SIP-AP authentication succeeds, and the 200 OK registration response message is sent to the terminal. ;

Steps 17~20: The SIP-AP uses the R01 message Query_Register_Info to SIPROUTE to query the forwarding address (that is, the routing information) of the registration request message. The SIPROUTE queries the database through the registered account of the user carried in the R01 message. Destination address and port; after the query is completed, the query result is sent to the SIP-AP;

Steps 21 to 24: After authenticating the registration request message sent by the UE A, the SIP-AP sends a SIP-AP_RES_ FROM_DAS_EVENT message to the SIPPXY; the SIPPXY judges the message and performs the necessary header. The domain processing is constructed as a new registration message: Add the Via header field, the Record-Route header field, the Route header field, update the Contact header i or update the Host portion of the Request-Uri. Send a registration request message to the AS according to the SIP-AP indication carried in the SIP-AP_RES_ FROM_DAS_EVENT message, and then set the timeout timer Timer2. After the AS returns the registration success, SIPPXY sends the SIP-AP-REGISTER-RES — TO— DAS — The EVENT message reports the registration response message to the SIP-AP, and records the number of registration response messages received; when all registration responses are received, the timeout timer Timer2 is cancelled, and the data area is released;

Step 25: The SIP-AP saves the current user's personal information to the memory and the SYBASE database, thereby completing the user registration process; Steps 26~27: When user A initiates a call request (INVITE) message to SIPPXY, SIPPXY sends a call request to the SIP-AP;

Steps 28 to 29: The SIP-AP receives the INVITE message to be forwarded, and sends a message to the SIPROUTE requesting to obtain the ROUTE information of the calling user UE A. The message structure is SAP_Query—RouteInfo; SIPROUTE will query this from the database. The user's subscription information is sent to the SIP-AP, including the Mode parameter mo (calling contract) and the SC parameters.

Steps 30 to 31: The SIP-AP sends a "Forwarding Request" to the SIPPXY. The INVITE indicates that the RouteMode in the header field is mode=mo. The SIPPXY distributes the INVITE message to the AS. The intelligent network service on the AS is based on the INVITE message header field. Mode and SC to trigger the calling process of the service;

Steps 32 to 37: After the triggering of the calling process is completed, the AS sends the INVITE to the SIPPXY. The SIPPXY reports the call request to the SIP-AP. The SIP-AP receives the INVITE message to be forwarded, and sends a message to the SIPROUTE to obtain the called party. The ROUTE information of the user UE B is sent to the SIPPXY to send a "forwarding request" to the AS, which triggers the called process of the intelligent network service.

Steps 38 to 42: After the triggered process of the intelligent network service is triggered, the AS sends the INVITE message to the SIPPXY, and the SIPPXY forwards the packet to the SIP-AP. The SIP-AP then goes to the SIPROUTE to query the next subscription information of the user B. If the user returns to the user, B has the service nesting function, then the next step 32~37, the next intelligent network service is continued to be triggered. If the user B queries the SIPBOUTE for the last subscribed intelligent network service, the SIPROUTE returns the user B to the SIP-AP. The address and port where the terminal is located, the SIP-AP directly calls the INVITE to the UE B, and the subsequent 100trying, 180, PRACK, 200PRACK, 200 INVITE, ACK and other signaling can interact normally, and the UE A and the UEB can normally talk. .
