Description

Message sending method, message authentication method and corresponding system

technical field

The present invention relates to the communication field or the computer field, and in particular to a message sending technology.

Background technique

With the development of mobile communication technology, various messaging services have appeared, such as SMS (Short Messaging Service, short message service), EMS (Enhanced Message Service, enhanced short message service), MMS (MultiMedia Service, multimedia service, namely MMS), etc.

The SMS service is mainly implemented by sending and receiving text messages through mobile devices. General SMS text information can be up to 160 bytes (about 80 Chinese characters, because other related information must be sent, so the general SMS service has a limit of 70 Chinese characters for Chinese), and about 1 second of voice The space occupied by the call is comparable, so the communication costs of this SMS service are very low. Message transmission is always relayed by SMSC (Short Messaging Service Center, Short Message Service Center) outside GSM (Global System for Mobile communication). SMSC related. GSM and subsequent networks provide support for SMS services.

The function of the EMS business is to process information such as simple images, sounds and animations in addition to sending and receiving text messages. EMS has played a very good role in the transition from 2G network to 2.5G network. Because the number of words occupied by images, sounds, and animations may vary greatly, the support for EMS requires changes to the operator's billing system.

The MMS service emerged with the popularization of GPRS (General Packet Radio Service, General Packet Radio Service) network or CDMA (Code Division Multiple Access, Code Division Multiple Access) 2000 1X (2.5G network). The MMS service is a non-real-time multimedia communication method based on a store-and-forward mechanism, enabling users to send and receive various types of information, including text, pictures, and multimedia information such as audio, email, and video. The storage and forwarding of different non-real-time multimedia communication methods (including two-way communication between mobile terminals and mobile terminals, and between mobile terminals and the Internet) can be realized through MMSC (Multimedia Message Service Centre, Multimedia Message Service Center).

At present, the above-mentioned various message services are widely used. For example, many SPs (Service Providers) can provide users with various contents such as weather forecast, jokes, entertainment, and news by sending short messages or multimedia messages. But at the same time, some unscrupulous SPs can also send text messages or MMS messages through the above-mentioned methods to defraud users and force them to bind customers.

In order to solve the fraudulent behavior of illegal SP, many operators use the authentication system to save the subscription relationship between the user number and the service code. Through the authentication system, it is authenticated whether the user has subscribed to the corresponding service at the SP, and the message is issued after the authentication is passed. The message sending process is shown in Figure 1, including the following contents:

In step 101, the SP submits messages to the message service center one by one for each user. Each message carries a user number and a service code.

In step 102, the message service center submits authentication requests to the authentication system one by one for each message, and each authentication request message carries a user number and a service code.

Step 103, the authentication system uses the subscription relationship between the user number and the service code stored in it to authenticate whether the user corresponding to the user number has subscribed to the service corresponding to the service code, and returns the authentication result.

In step 104, the message service center determines that the authentication is passed according to the authentication result, then sends a message to the user corresponding to the user number, and executes step 105, that is, returns a status report to the SP. If the message service center determines that the authentication fails according to the authentication result, it directly rejects the delivery of the message, and executes step 105, that is, returns a status report to the SP.

Under the existing process, the message service center needs to submit authentication requests to the authentication system one by one for each user who subscribes to the same service, and the authentication system returns the authentication results in turn. Occupies a certain amount of air interface resources, so this message sending method will result in waste of air interface resources, and affect the speed and success rate of sending messages.

Detailed ways

The first embodiment of the present invention provides a message sending method, which can process multiple users subscribing to the same service data as one user group, thereby saving air interface resources and improving the speed and success rate of sending messages. Before implementing the first embodiment, the following operations need to be performed:

According to the service type, all users subscribing to the same service are divided into a user group, and the user group is coded to obtain the user group number. For example, divide the user numbers corresponding to the users who subscribe to the daily news service (the service code is 222) into the same user group, and encode the user group to obtain the user group number 222. Alternatively, according to the service type and application service equipment (such as the application service equipment on the service provider side), all users who subscribe to the same service of the same application service equipment are divided into one user group, and the user group is encoded to obtain User group number. The service code can be used as the user group number of the user group, for example, the user numbers corresponding to the users who subscribe to the daily news service (service code 222) of SP-A (service code 1111) are divided into the same user group , and encode the user group to obtain the user group number 1111222. It is also possible to randomly select other codes, such as AAA, as the user group number of the user group.

Corresponding the service code of the service ordered by the user and the user number of the user with the user group number of the user group, that is to say, establishing the user group number corresponding to the user group number and the user group number The corresponding relationship between all user numbers, such as user group number 1111222 corresponds to user number: 1391...7, 1372...8, etc., save the corresponding relationship in the authentication system and application service equipment (such as service provider ); establish the corresponding relationship between the user group number and the service code of the service ordered by the user group, such as the user group number 1111222 corresponds to the service code 222, and save the corresponding relationship in the authentication system.

The authentication system and the application service device can be synchronized regularly to maintain the consistency of the user group number stored in the authentication system and the application service device, the user number corresponding to the user group number, and the like.

The implementation process of the first embodiment is shown in Figure 2, and includes the following contents:

Step 201, obtain the service message issued for the user group, and obtain the user group number and service data from it.

The message forwarding device obtains the service message issued by the application service device for the user group, and the service message carries the user group number and service data. The message forwarding device obtains the user group number and service data from the service message.

Step 202, according to the correspondence between the saved user group number and all the user numbers in the user group corresponding to the user group number, determine the user number belonging to the user group corresponding to the user group number; The stored correspondence between the user group number and the service code of the service ordered by the user group corresponding to the user group number determines the service code corresponding to the user group number.

Because the correspondence between the user group number and all user numbers in the user group corresponding to the user group number is stored in the authentication system, and the service ordered by the user group number corresponding to the user group number is stored Therefore, through the authentication system, the user number belonging to the user group corresponding to the user group number can be determined according to the user group number obtained by the message forwarding device, and the The service code corresponding to the user group number mentioned above.

In step 202, the authentication system may also interact with the charging system to obtain the charging status of the user number, and further determine the validity of the user number according to the charging status. Of course, it is also possible to determine whether the user number is valid according to other conditions.

Step 203, sending the service data and service code to the user corresponding to the user number.

If it is determined in step 202 that the user number is valid, it is also necessary to send a message according to the validity of the user number. For example, only send service data and service codes to valid user numbers, and refuse to send service data and service codes to invalid user numbers.

The above method may further include: feeding back a message status report to the application service device that sends the service message.

An application of the first embodiment is given below, and the application is aimed at issuing weather forecast service messages. Before implementing the application, it is necessary to divide all users who subscribe to the weather forecast service into the same user group, and provide A user group number is assigned to a group, for example, AAA is selected as the user group number of the user group. Corresponding the service code of the service ordered by the user and the user number of the user with the user group number of the user group, that is to say, establishing the user group corresponding to the user group number AAA and the user group number Correspondence between all user numbers (1391...7, 1372...8, etc.) The corresponding relationship between the group number AAA and the service code 333 of the service subscribed by the corresponding user group, such as the user group number AAA corresponding to the service code 333, and the corresponding relationship is saved in the authentication system.

The specific flow of the application is shown in Figure 3, including the following:

Step 301, the service provider sends a service message to the message service center for the user group, the message carries service data, namely weather forecast service data, and the user group number AAA corresponding to the user group of the user who subscribed the service data.

Step 302, the message service center submits the user group number AAA to the authentication system, and indicates that the feedback type is group member query result.

The message service center can save the business data, submit the user group number AAA to the authentication system, and indicate the feedback type as the group member query result.

Step 303, after the authentication system receives the user group number submitted by the message service center, it determines the corresponding service code 333 according to the correspondence between the user group number AAA and the service code 333; and, according to the user group number AAA and the user Correspondence between numbers, determine all user numbers belonging to the user group corresponding to the user group number: 1391...7, 1321...9, 1372...8, etc., and determine all user numbers , and return the valid user number (eg, 1391...7, 1321...9) and service code 333 to the message service center, and indicate whether the return is complete. And, return the invalid user number (eg, 1372...8) and service code 333 to the message service center, and indicate the invalid reason.

In step 303, the authentication system can interact with the billing system, and determine the validity of all user numbers in the user group according to the billing situation in the billing system, such as 1372...8 arrears, then determine that the user number is invalid , otherwise, determine that the user number is valid. Of course, the first embodiment of the present invention is not limited to using this method to determine the validity of the user number, and it can also be implemented in other ways, which are not exhaustive here.

Step 304, after receiving the valid user code and service code fed back by the authentication system, the message service center sends a service message to the valid user number, and the service message carries the service data and service code corresponding to the service code; and executes step 305, That is, a status report is returned to the service provider. After the message service center or gateway receives the invalid user code fed back by the authentication system, it directly rejects the delivery of the service message, and executes step 305, that is, returns a status report to the service provider, explaining the reason for the failure.
