Authentication and Accounting Method in Internet Personal Number Service

technical field

The present invention relates to the field of IP (Internet Protocol: Internet protocol) communication technology, and more precisely relates to a new authentication and billing method in the Internet personal number service (ONLY: One Number Link You), which can be used in ONLY business and other new IP communication services.

Background technique

With the development of the Internet, Internet users are increasingly demanding a convenient means of communicating with each other and obtaining information anytime and anywhere. The ONLY service is designed to meet the needs of users by integrating traditional telecommunications technology and IP technology. An innovative business developed on the basis of The core idea of the ONLY service is to assign an ONLY number to each user, regardless of whether he is a telephone user or a PC user, and regardless of whether the user is surfing the Internet, through the ONLY system and using the ONLY number, the call can be made to the fixed line of the ONLY user. (office phone, home phone), mobile phone (mobile phone), pager, PC, etc. are connected to realize four services: phone to phone, phone to PC, PC to phone, and PC to PC.

The ONLY service solves the number problems, billing problems, mapping problems of multiple phone numbers, and user mobility problems when PC users and ordinary phone users communicate with each other. To use the ONLY service, the user only needs to apply for an ONLY number (a virtual number, such as a special service number 166 plus an 8-digit number ×××××××× including the area code), and no matter where the user goes, other Users can use the ONLY number to contact him by using equipment such as telephones and PCs. The method for ONLY users to receive information can be based on the user's own settings, establish real-time contact with the calling user by telephone or PC, or listen to the message by voice mailbox.

To realize ONLY business, it is necessary to set up an ONLY server (ONLY Server) and a user server (User Server, which can be shortened to US). The ONLY server is used to complete the connection control of all business users. Once the ONLY number of the called user is obtained, the call will be connected to the ONLY server first, and then the ONLY server will perform subsequent connection operations to ensure the unified management of PC users and Phone users; the user server (US) is responsible for the calling strategy Control, policy control can be customized by the user (for example, rules for transfer in case of busy), and stored in the ONLY database. When an ONLY call comes, the ONLY server queries the user server, and the user server obtains the user's pre-customized call path by accessing the database, and then transfers it to the corresponding call device. If the call is made to an ordinary phone or a mobile phone, the ONLY server initiates a call to the IP telephony gateway (GW) where the called number is located; if the call is made to a PC client, the ONLY server initiates a call directly to the called user end; , the ONLY server transfers the call to the user's voice mailbox.

Shown in Fig. 1 is to realize the networking structure and call flow of ONLY business, the calling party user calls the ONLY number, and the call of all calling ONLY numbers can be all routed on the ONLY server 104 through gateway (GW) 102 or 103, ONLY server 104 Send a request to the user server (US) 105, and the user server (US) 105 queries the database, obtains the actual phone number or IP address that should be connected at present according to the current state of the called user and the registration data, and returns to the ONLY server 104, the ONLY server 104 With the support of the gatekeeper (GK) 101, a call is initiated via the gateway (GW) 102 or 103 and the public telephone network (PSTN) 109 or 123 to the actual telephone number of the called user or directly to the IP address. What the user server (US) 105 returns to the ONLY server 104 is one or more phone numbers and IP addresses customized in advance according to the called user.

Authentication and billing is a very important functional part of the ONLY service, which occurs between the ONLY server and the user server (US). The current international standard protocols for authentication and billing include RFC2138 and RFC2139. The existing RADIUS: Remote Authentication Dial inUser Service is mainly used to meet the requirements of AAA (authentication authentication) in access and traditional IP communication services. , the abbreviation of authorization and accounting function: Authentication, Authorization and Accouhting) function realization, but because the protocol is based on the user datagram protocol (UDP: user datagram protocol) for data message transmission, although it has the advantage of simple implementation, but The reliability of data message transmission cannot be guaranteed, and various functions such as registration (registration) and logout to the server, and heartbeat between the server and the client cannot be realized, so it cannot meet the needs of ONLY business, that is, it cannot meet the needs of ONLY business. Authentication and accounting requirements for the function.

Contents of the invention

The purpose of the present invention is to design an authentication and billing method in the Internet personal number service (ONLY) in order to realize the multi-functional authentication and billing requirements in the ONLY business, which can satisfy the required registration, registration or billing in the ONLY business. Functions such as logout, maintaining heartbeat connection, billing and authentication, etc., ensure the reliable transmission of data packets.

The authentication and billing method in the Internet personal number service (ONLY) of the present invention is to use the transmission control protocol (TCP) to transmit login request/logout and response message, heartbeat between the Internet personal number service (ONLY) server and the user server. and responding to heartbeat response messages, call request and response messages, Internet personal number service (ONLY) server notification and response messages, and charging request and response messages.

The technical solution for realizing the object of the present invention is as follows: an authentication and charging method in Internet personal number service, which is characterized in that it includes the following steps:

A. After the transmission control protocol connection is established between the Internet personal number service server and the user server, the Internet personal number service server sends a login request message to the user server. When the user server judges that the login information is legal and the system is not busy, the Internet personal number service server Sending a response login response message, the user server sends a login rejection response message to the Internet personal number service server when judging that the login information is illegal or the system is busy;

B. After the Internet personal number service server logs in to the user server successfully, the Internet personal number service server starts the heartbeat timer to start counting, and within the heartbeat time interval, when the Internet personal number service server receives any response message from the user server, resets the heartbeat timer, and after the heartbeat timer time reaches the heartbeat time interval, when the Internet personal number service server does not receive any response message from the user server, it sends a heartbeat message to the user server, and the user server sends a message to the Internet personal number The business server sends a response heartbeat response message;

C. When the Internet personal number service server receives the call request from the gateway, it sends a call request message to the user server, and the user server sends a response call response message to the Internet personal number service server when it judges that the call request information is legal and the system is not busy , when the user server judges that the call request information is illegal or the system is busy, it sends a call rejection response message to the Internet personal number service server;

D. After the Internet personal number service server receives the response call response message from the user server, the Internet personal number service server directly initiates a call to the called user. If the call to the called personal computer is unsuccessful, the Internet personal number service server Send an Internet personal number service server notification message to the user server, and then the user server sends a notification message to the called personal computer, the called personal computer sends a notification response message to the user server, and the user server sends a notification message to the Internet personal number service server. notification response message;

E. When the call stops, the Internet personal number service server sends a billing request message to the user server for the user server to generate a billing bill, and the user server receives the billing request message and sends the billing request message to the Internet personal number service server A response message for the Internet personal number service server to delete the corresponding charging request message;

F. When the Internet personal number service server stops running, it sends a logout request message to the user server, and the user server does not respond to the received logout request message.

The login request message in the step A includes at least the identification number and password of the Internet personal number service server; the response login response message includes at least the heartbeat time interval and the maximum number of retries, and the login rejection The response message at least includes information about the reason for the login failure.

In the step B, any response message includes any data message and heartbeat response message.

In the step C, the call request message includes at least the number information of the calling party and the called party; the response call response message includes at least all called numbers pre-customized by the called party; the The response message of call rejection includes at least the reason information of call failure.

In the step E, the charging request message at least includes a charging ID, which is generated according to the calling ID, and the charging ID is absolutely unique and printable.

The described generation of charging identification according to the call identification further includes:

a. Set the charging identification to be composed of 32 printable characters, and each character of the charging identification is represented by 4 binary digits;

b. Take the call identification composed of 16 characters, and each character of the call identification is represented by 8 binary bits;

c. Let each call identification character correspond to two billing identification characters, use the high 4 bits in the 8 binary bits of a call identification character to correspond to represent 4 binary positions of a charging identification character, use this call identification character The lower 4 bits of the 8 binary bits correspond to the 4 binary bits representing another charging identification character.

The multifunctional authentication and billing method of the present invention refers to the international standard protocols RFC2138 and RFC2139 about authentication and billing, and the transmission of the message adopts the Transmission Control Protocol (TCP: Transfer Control Protocol), which meets the requirements of ONLY business. The functions of registration, logout, maintaining heartbeat connection, billing and authentication ensure the reliable transmission of data packets.

Detailed ways

See Figure 1. In principle, the ONLY service has nothing to do with the specific network environment, and can be implemented under different networks. However, in order to maximize the use of the existing IP gateway functions, it can be used as shown in Figure 1. The network structure of the ONLY system (one of the network structures of the ONLY system), realizes the ONLY business on the Internet, and implements the new multifunctional authentication and charging method of the present invention. The function of each functional component in the figure is:

Gateways (GW: Gateway) 102, 103 complete the conversion of signaling and voice between the public switched telephone network (PSTN) and the Internet (IP);

Gatekeeper (GK: Gatekeeper) 101 completes functions such as access control, routing search, bandwidth control, etc., and mainly completes querying the corresponding called GW according to the telephone number;

ONLY server (ONLY server) 104 is used to complete the conversion between H.323, SIP (Voice over IP protocol) and MGCP (Media Gateway Control Protocol) protocols. H.323 protocol is generally adopted between ONLY server and GW, and ONLY server It adopts SIP or MGCP protocol with IVR MS, VoiceMsg MS, Resident GW, Fax S&F, and PCC. The ONLY server is also responsible for interacting with the User server to complete the authentication and billing functions. The ONLY server completes the function of call control in the IP network. It is equivalent to the switch in the PSTN network, but it is located in the IP network, and the technologies used are all related to IP. ONLYserver only processes signaling and does not process voice media streams;

User server (User Service) 105, receives the request of ONLY server 104, completes authentication and accounting functions, including user information registration, query, modification, deletion, etc.;

Directory server (Index Server) 106 is a database system, which completes the preservation of user information;

Web server (Web Server) 107, provides a kind of method that can carry out weekly household information registration, inquiry, modification, deletion street etc. by Web to the user;

Interactive Voice Response Media Server (IVR MSI: interactive Voice Response MediaServer) 114, can receive the user's key input and voice input, and make different responses according to different applications, such as completing the telephone banking function;

Voice Mail Media Server (VoiceMsg MS: Voice Message Media Server) 115 can complete the voice mail function on the IP network, and 108 is a voice storage server (Content Server), which provides voice access services for 114 and 115;

Resident Gateway (Resident GW: Resident Gateway) 117, the feature of this gateway is that it can directly connect to the telephone line and connect to ordinary telephones, without the need for switches and other equipment;

Store and forward fax media server (Fax S&F: Fax Store and Forward Media Server) 116, which can receive fax data from GW or other IP terminals, and forward it in an appropriate way, such as E-mail, ordinary fax, etc. ;

The PC client (PCC: PC Client) 118 is a software running on the PC, which is the software for realizing the voice communication of the PC client, and can carry out voice communication with other devices.

The telephones (Telephone) 110, 119 shown in the figure, the facsimile machines (Fax) 111, 120, the portable computers (Laptop computer) 113, 122 and the modem (Modem) 112, 121 are all client equipments.

Referring to FIG. 2 and referring to FIG. 1 together, the figure shows a basic flow of the ONLY service network.

(1) The calling user picks up the phone and dials the ONLY number of the called ONLY user, such as 16612345678. After the PSTN switch receives the ONLY number 16612345678, it connects the call to the GW according to the route preset by the ONLY number user ;

(2) GW receives the call, sends the number 16612345678 to GK, and requests route analysis;

(3) GK returns the IP address of ONLY Server to GW;

(4) GW initiates a call to ONLY Server;

(5) ONLY Server receives the call and sends a call request message to the US, that is, the 16612345678ONLY number is sent to the US for number change;

(6) The US transforms the virtual ONLY number into an actual number that can be used to contact the called user. Assuming that the user first corresponds 16612345678 to his PC when ordering, the US returns the ONLY Server's response call response message Contains the IP address and port number of the user's PC;

(7) After the ONLY Server judges that the returned number is PCC, it initiates a call to PCC;

(8) If the PCC is inside the firewall at this time, the call fails;

(9) ONLY SERVER sends a notification message to the US;

(10) US will send a notification to PCC according to the message and the user's settings, and send the corresponding message;

(11) PCC sends notification response to US;

(12) The US sends a notification response message (response message) to the ONLY Server according to the PCC user's notification response, assuming that the user's response at this time is to call his temporary mobile phone 01082881234;

(13) After the ONLY Server judges that the returned number is an ordinary mobile phone number, it sends the number to GK for routing analysis;

(14) GK performs routing analysis, and returns the routing analysis result to ONLY Server, which is a mobile phone number of GW in Beijing;

(15) ONLY Server initiates a call to the GW in Beijing, and the GW calls out to the PSTN network again, so that the called user's phone with the number 01082881234 starts ringing, and the gateway connection is established;

(16) After the called user picks up the phone, the conversation path is established, and both parties can talk;

(17) The conversation between the two parties;

(18) When the called party hangs up, the voice channel is disconnected and the gateway withdraws the line;

(19) At this time, ONLY SERVER sends a billing request message to the US, and generates a billing identification (ID) when generating the billing message;

(20) US sends a billing response message to ONLY SERVER;

(21) The caller hangs up.

In the above process, three kinds of messages are involved: call request and response message between ONLY SERVER and US; notification and response message between ONLY SERVER, US and PCC; and billing request and response message between ONLY SERVER and US. reply message. The transmission of the message adopts the TCP protocol.

About call request and reply message.

The ONLY Server sends a call request to the User Server, and the request information contains the calling and called numbers. If the User Server thinks that the call request information is legal and there are no other abnormal conditions (such as the system is busy), it should return an Ack message. The information contains a list translated according to the called number. The list lists the call forwarding routes customized by the called party when applying for the ONLY service, such as the phone number of fixed phone 1, phone number of fixed phone 2...mobile phone number... Pager number...the IP address and port number of the PC, etc.; if the User Server thinks that the call request information is illegal, or has other abnormal conditions (such as the system is busy), it will return a rejection message (Rej) to the ONLY Server and reject the ONLY Server's request. For a call request, the reason for the failure of the call request should be included in the returned rejection information (Rej).

Regarding notification and response messages.

When the ONLY Server sends a call request to the User Server and receives the corresponding call request from the User Server through the response (Ack) message, the ONLY Server will directly make a call to the called user (including the telephone user or PC user), and then to the PC user If the call is unsuccessful, if the firewall of the PC user blocks the ONLY Server's incoming signaling, then the ONLY Server should send a notification message to the User Server, and the User Server will use this message and the preset settings of the called user Send a corresponding message to User ServerClient, and send a reply message to ONLY Server according to the response of the called user.

Regarding accounting request and response messages.

When the call stops, the ONLY Server sends a billing request message to the User Server for the User Server to generate a billing bill. The billing request message contains a billing identification (ID), and the billing ID is the call ID of the gateway Generate a unique printable Billing ID. The call ID is generated according to the H323 protocol, and is composed of 16 characters that may not be printed. The billing ID of the present invention produces 32 billable ID characters that can be printed according to the 16 characters of the call ID. One character corresponds to two billing ID characters, and the corresponding relationship is: each call ID character is represented by 8 binary bits, its high 4 bits correspond to a billing ID character, and its low 4 bits correspond to a billing ID character. ID characters, the characters of the two billing IDs have a total of 4 binary digits ranging from 0 to 15, which can just establish a one-to-one correspondence with the characters 0-7 and A-F. After User Server receives the accounting request message from ONLYServer, it will respond the accounting message to ONLY Server for ONLYServer to delete the corresponding accounting request message.

Referring to Figure 3, the figure shows the process of the ONLY server interacting with the User server to complete the TCP connection.

(1) When a TCP connection is established between ONLY SERVER and US, ONLY SERVER sends a login (registration) request message to US;

(2) US judges the legality according to the user identification (ID) and password, and returns the corresponding response message;

(3) After the ONLY SERVER registers successfully, it sends a heartbeat message to the US;

(4) US responds to ONLY SERVER with a heartbeat response message;

(5) When the ONLY SERVER stops running, it sends a logout request message to the US.

The transmission of the above message adopts the TCP protocol.

When the ONLY Server starts, the ONLY Server sends a login request to the User Server, and the request information contains the identification (ID) number and password of the ONLY Server; When busy, should return the response message that login passes, wherein contain heartbeat time interval and maximum number of retries, system enters heartbeat signal process and call process (step 202); If User Server thinks that this login request information is illegal, or has other In abnormal circumstances, such as the system is busy, a response message of denial of login will be returned to the ONLY Server, and the login of the ONLYServer will be rejected. The response message should also provide the reason for the failure of the login request.

ONLY Server should send a heartbeat message after the communication link between ONLY Server and User Server is idle for a certain period of time. After the system enters the heartbeat signal process, start the heartbeat timer to start timing. The heartbeat time interval and the maximum number of retries are specified in the login request response message provided by the User Server to the ONLY Server. For example, the default value is sent once every 10 seconds. The maximum number of retries is 5. If the ONLY Server does not receive any message from the User Server within 10 seconds from the start of the heartbeat timer, it will send a heartbeat message. If no response is received after sending 5 times, it is considered that the User Server has Fault, within 10 seconds from the start of the heartbeat timer, if the ONLY Server receives any message from the User Server, it will reset the heartbeat timer and start timing again.

When the ONLY Server stops running, the ONLY Server sends a logout request to the User Server. After receiving the message, the User Server should consider that the ONLY Server has left the login state. At this time, the User Server does not need to send a response message to the ONLY Server.

The present invention realizes the information interaction between the ONLY Server and the User Server in the ONLY service through the multifunctional authentication and billing process including registration, logout, heartbeat, etc., and has the advantages of reliable, fast and efficient transmission.

The multifunctional authentication and billing method of the present invention adopts the TCP protocol as the transmission protocol, and uses six types of messages to realize multiple interactions between the ONLY Server and the User Server, and is applied in the ONLY business, which has excellent practicality. At the same time, it can also be applied to new IP communication services.
