TECHNICAL FIELD The present invention relates to mobile intelligent network services, and in particular, to a method for providing short message intelligent services to intelligent users on a mobile intelligent network. BACKGROUND OF THE INVENTION In recent years, intelligent network technology and mobile communication services have developed rapidly around the world. The combination of these technologies constitutes a mobile intelligent network, which provides a variety of intelligent services for many mobile users. The biggest feature of the intelligent network is the separation of switching and services. The basic idea is that the switch performs the most basic connection functions, and all other value-added services are completed by the intelligent network. The intelligent network is mainly composed of a service switching point (SSP), a service control point (SCP), an intelligent peripheral (IP), a service management system (SMS), and a service generation environment (SCE). The SSP completes the switching function. Various events during the call are reported to the SCP and the call may be suspended, waiting for further instructions from the SCP. The SCP is responsible for completing business logic control functions. The mobile intelligent network is an intelligent layer superimposed on the mobile communication network. The intelligent network structure and control functions are used to realize the intelligence of many value-added services on the mobile network.

At present, in the GSM network, the short message service provides a lot of convenience for mobile users, including a variety of attractive value-added services, such as: sending and receiving short messages; querying weather, flights, stocks, etc. through short messages. Information and more. The short message center intelligent service is to provide short message services to intelligent network users. It is an organic part of the intelligent service. However, the current mobile intelligent network does not have the capability to open various short message-related intelligent services and cannot provide short message functions to users of the intelligent network. Since the mobile intelligent network cannot provide a short message intelligent service, for the short message industry Services cannot realize some value-added services such as prepayment, which affects the use of users and the maintenance of operators, which is extremely inconvenient. SUMMARY OF THE INVENTION In view of this, the main object of the present invention is to provide a method for providing a short message intelligent service on a mobile intelligent network, so that the short message function can be flexibly and conveniently opened on the mobile intelligent network, and further make the calculation of the mobile intelligent network The fee system is more complete.

To achieve the above object, the technical solution of the present invention is implemented as follows:

A method for providing a short message intelligent service on a mobile intelligent network includes at least the following steps: a. Establishing a short message service center (SMSC) and a mobile intelligent network respectively;

b. setting a logical interface between the SMSC and the mobile intelligent network service control point (SCP) to which it is currently connected;

c SMSC communicates with SCP through message conversion on this interface to further trigger short message intelligent services.

In step c, the SMSC communicates with the SCP through a logical interface message conversion, and further includes:

cll. establishing a TCP / IP socket (Socket) connection between the SMSC and the logical interface; cl2. establishing a TCP / IP socket connection between the logical interface and the SCP;

cl3. The SMSC sends a standard operation message to the logical interface;

cl4. The logical interface converts the received operation message into a message recognized by the SCP and sends it to the SCP.

Step b further includes: setting the current SMSC to connect to at least one SCP of the mobile intelligent network. Step b further includes: setting at least one SMSC to the current SCP. In the above communication process, it is set that the standard operation message sent by the SMSC to the logical interface and the identifiable message sent by the logical interface to the SCP are composed of a message header and a message body. The message header includes at least the version of the message body and the address of the protocol sender , The address of the protocol receiver and the length of the message body, and the message body at least includes specific information to be sent by the user. Among them, set the unused field in the message body to 0 or NULLo

In step c, the SMSC communicates with the SCP via a logical interface message conversion to further trigger an authentication operation. The authentication operation includes at least the following steps:

c21. After the SMSC receives the request from the mobile intelligent network user to send a short message, it sends an authentication operation request message to the SCP of the mobile intelligent network;

c22. After receiving the authentication operation request message, the SCP queries whether the user has the right to send a short message, and then sends the query result back to the SMSC through an authentication request response message;

c23. After receiving the response message, the SMSC makes corresponding processing according to the authentication result.

The authentication operation request message in step c21 includes at least a short message center address, a source address, a destination address, a calling party / called party identifier, and a service key.

During the authentication operation, step b further includes: the short message center determines a destination service control point in the mobile intelligent network to which the current SMSC is connected according to the number segment of the source address in the authentication operation request message.

The authentication request response message in step c22 includes at least the operation result and the selected notification mode. Wherein, the selected notification mode is to send a short message sending result notification regardless of the success or failure of the operation, or only send a short message sending result notification when it fails, or only send a short message sending result notification when it succeeds, or whether the operation is successful or None of the failures will send a short message notification of the result. And, the method further includes: presetting an operation result value in the authentication request response message to 0 when the authentication operation is successful; and an operation result value in the authentication request response message to 1 when the authentication operation fails. In step c, the SMSC communicates with the SCP through a logical interface for message conversion, and can further trigger a short message result notification operation. The short message result notification includes at least the following steps: c31. After the mobile intelligent network user sends the short message, the SMSC Send a short message result notification message to the SCP to inform the SCP whether the short message was sent successfully;

c32. After receiving the short message result notification message, the SCP returns a corresponding short message result notification response message to the SMSC according to the sending result; at the same time, the SCP chooses to perform subsequent service processing according to the sending result.

The short message result notification message described in step c31 includes at least a short message center address, a source address, a destination address, a caller / called party identification, a transmission result, and a service key. When the sending of the short message is successfully set, the sending result value in the short message result notification message is 0; when the sending of the short message fails, the sending result value in the short message completion notification message is 1.

The short message result notification response message described in step c32 includes at least the operation result. In addition, when the short message result notification operation succeeds, the operation result value in the short message result notification response message is 0; when the short message result notification operation fails, the operation result value in the short message result notification response message is 1.

The core of the method of the present invention is to use a short message system and a mobile intelligent network to construct a separate solution, and set a logical interface between the SMSC and the SCP. The SMSC and the SCP use the short message point-to-point protocol (SMPP) and extended short messages through this interface The interface (EMSI) performs message communication, and the two parties send a TCP / IP data packet through a Socket connection established in advance to implement functions such as short message authentication and charging for smart users.

An SMSC can be connected to multiple (but limited) SCPs to provide services for users of these SCPs. At the same time, multiple SMSCs can establish connections with the same SCP as needed, so the relationship between SMSCs and SCPs is many-to-many Relationship, SMSC can confirm the application by the number segment in the source address Which SCP to go for authentication, and to which SCP the billing information should be sent.

In response to the requirement of mobile smart users to open the short message function, it is necessary to implement the trigger of the short message intelligent service, which mainly involves two major parts: authentication and short message result notification. The so-called authentication means that when a smart user wants to send a short message, the SMSC first queries the SCP through the authentication operation to see if the user can send a short message; then, the next step is to be processed according to the SCP query result. Short message result notification refers to the result notification after a smart user sends a short message. As long as the triggering of the short message intelligent service is completed, various short message intelligent services, such as billing, can be realized on this basis.

From the above analysis, it can be seen that the method for providing a short message intelligent service on a mobile intelligent network provided by the present invention is to trigger the SMSC intelligent service through the TCP / IP protocol, which has the following advantages:

(1) It can be quickly implemented: The present invention only relates to a part of short message service center (SMSC) equipment, and has no influence on other equipment on the network;

(2) Full network coverage of intelligent services can be achieved: as long as an interface application part is added and set, the short message function can be opened for mobile intelligent users on the entire network;

(3) Interoperability with equipment of other manufacturers: The SMSC intelligent service TCP / IP protocol is only an application layer entity protocol for other manufacturers;

(4) For network construction, there are minimal changes involved: Only a logical interface needs to be set on the SCP of the mobile intelligent network. The interface uses standard interface protocols to communicate with the outside, and uses internal protocols to communicate with the SCP. When the external interface changes In this case, you only need to change the corresponding processing, and do not need to change the internal interface with the SCP, which is simple and convenient.

(5) Can smoothly transition to a standard mobile intelligent network. Brief description of the drawings FIG. 1 is a schematic diagram of a system structure of the present invention. Modes for Carrying Out the Invention The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1, the present invention separately constructs a short message center and a mobile intelligent network. One SMSC can be used by multiple (limited) SCP users, and at the same time, for the case where the called party (MT) is authenticated, many Each SMSC may need to establish a connection with the same SCP, so the relationship between SMSC and SCP is a many-to-many relationship. The SMSC distinguishes which SCP should go to for authentication and the SCP to which the billing information should be sent.

An interface is set up between the SMSC and the SCP. This interface refers to a logical entity, which can be called a front-end processor, and it completes the conversion of the data packet format, data type, and protocol between the SMSC and the SCP to implement intelligent user Short message authentication and billing functions. This front-end processor is located in front of the SCP entity. It uses internal protocols to communicate with the SCP, and communicates with other external entities using standard interface protocols. When the external interface changes, only the corresponding processing part on the front-end processor is changed. There is no need to change the internal communication with the SCP. interface. The process of establishing communication between the SMSC and SCP using this interface is as follows: When communication is needed between the SMSC and the SCP, the TCP / IP Socket connection is first established by the SMSC and the front-end machine, and then the TCP / IP is established by the front-end machine and the SCP. Socket connection; then the SMSC sends a communication message in the standard protocol format to the front-end machine, the standard protocol format here refers to SMPP + EMSI; after receiving, the front-end machine converts the message into a data format that the SCP can recognize, And sent to SCP.

The present invention is a trigger for hosting SMSC intelligent services through the TCP / IP protocol. The specific operation is as follows: When SMSC receives a short message, it determines whether it is a smart user according to the number segment. If it is not, the service is performed according to a common process. The user then determines which SCP user should be based on the number segment, and then queries the corresponding SCP for user permission information. Query SCP at all SMSCs During the process of the message and the SCP's response to the SMSC, both parties use a Socket connection established in advance and send it using TCP / IP data packets.

The messages used between the SMSC and SCP are composed of a message header and a message body. The message header mainly describes the version of a message body, the sender of the protocol, the receiver, and the length of the message body. The message body refers to the content of the message. Specific information sent by the user. Fields not used in the message body must be set to 0 or NULL depending on the field type. The SMSC and SCP use the SMPP layer signaling interaction status (Command_status) to determine whether the signaling transmission between the two parties is normal, that is, to confirm whether the two parties are communicating normally. The definition of this state is shown in Table 1:

Table 1 State definitions

In response to the requirement of mobile smart users to open the short message function, it is necessary to implement the trigger of the short message intelligent service, which mainly includes two parts: authentication and short message result notification.

Among them, the authentication operation is that when a smart user wants to send a short message, the SMSC needs to query the SCP to send the relevant service information of the short message to the SCP through the authentication operation. The SMSC performs the next processing according to the instruction of the SCP. The so-called instruction is Refers to the SCP query result, that is, whether the user can use the required service, and if not, what is the reason.

The specific operation process of the authentication operation is as follows: When an intelligent network user wants to send a short message, the SMSC first sends an authentication operation request message to the SCP; the SCP queries whether the user has the right to send a short message, and then passes the query result The authentication response message is sent back to the SMSC; the SMSC performs corresponding processing according to the authentication result.

The message format used in the authentication operation is shown in Tables 2 and 3: Basic field description

SMSC— Address

Source- Address

Destination-Address

MO— MT— Flag MO / MT

ServiceKey Service Key Table 2 Authentication Operation Request Message Format Field Description

Operation_Result 0: The operation was successful

Non-zero: the operation was unsuccessful

Notify— Mode 1: Send notification of short message, no matter

Send success or failure

2: Send only on failure

3: Send only on success

4: Do not send the authentication request response message format regardless of success or failure. For example, if an intelligent network user wants to conduct mobile banking services through a short message service, then the intelligent network user first sends a request message to SMSC. SMSC After receiving the request, the SCP sends an authentication operation request message to the SCP. After receiving the authentication request, the SCP queries the corresponding user information according to the source address and service key in the authentication operation request message parameters, and sources the information in the short message service. The address is the mobile phone number, the service key is the service code of mobile banking, and the user information refers to whether the user's prepaid balance is 0, the user status is activated or disabled, etc .; SCP then confirms whether the user is based on the user information Have the right to send short messages, and pass the authentication The response message is sent to SMSC. If the service is not available, the reason for the unavailability must be explained at the same time. The SMSC then processes it according to the authentication result. If the user is allowed to send a short message, the mobile banking inquiry is continued. Otherwise, the notification is notified. The smart user is not allowed to operate.

The short message result notification refers to the result notification after the smart user sends a short message, and the SCP service can select the subsequent service processing according to the result. The specific operation process includes at least the following steps: After sending a short message to the mobile intelligent network user, the SMSC sends a short message result notification message to the SCP to inform the SCP whether the short message sending is successful; after the SCP receives the short message result notification message According to the sending result, the corresponding short message result notification response message is returned to the SMSC; at the same time, the SCP chooses to perform subsequent service processing according to the sending result.

The message formats used for short message result notification are shown in Tables 4 and 5:

Short message result notification response message format

After the two major parts of the mobile intelligent online short message intelligent service trigger are implemented, it can be implemented Now the mobile intelligent network provides short message functions, which can further complete intelligent services such as billing. Operators can set various billing methods according to actual conditions or user needs: such as real-time billing and billing according to the number of sent short messages. It is flexible and convenient, and easy to maintain. Since the billing method can be defined on demand, it can further provide pre-paid services, making it easier for users to use.
