Send to the user terminal.

The service control point 103 performs a corresponding service operation according to the service request message (for example, when the service operation is to query the account information, query the account of the user to obtain the account information), and send the service operation result (for example, if the service operation is a query account) In the case of information, the result of the operation is the account information of the user obtained by the query) to the mobile switching center 102, and the mobile switching center 102 transmits the service operation result to the terminal user through the base station controller 101.

The service control point further includes a judging device 1031. Before the processing of the service request message, the service control point 103 further processes the call request message forwarded by the mobile switching center 102, and the determining device 1031 uses the determining device 1031. The user makes a legality judgment to determine whether the end user activates the prepaid service and can perform the business operation. If the end user has been activated The prepaid service and the service operation can return a call response message to the mobile switching center 102, so that the mobile switching center 102 can continue the service request operation. If it is determined that the terminal user is illegal, the call application is rejected.

2 shows a flow chart of a method for performing business operations on prepaid user data according to the present invention.

The method for performing service operations on the prepaid subscriber data is used in a mobile communication system including a base station controller BSC, a mobile switching center MSC, and a service control point SCP. The method includes the following steps: Step S201: The terminal user needs to perform recharge When the service is queried, the service dials the corresponding recharge inquiry service, and the base station and the base station controller send a call message to the MSC;

Step S202: After receiving the call message, the MSC sends a call application message to the SCP. Step S203: The SCP determines that the user activates the prepaid service and the user can perform the recharge inquiry service operation, and sends a call application response message. The MSC is instructed to continue the call processing. Step S204: After receiving the response message of the SCP, the MSC sends a service request message to the SCP. The sending service request process may be that the MSC directly sends the service request message to the SCP, or may be sent by the MSC. The service request message is forwarded to the SCP by the HLR or other signaling transfer device.

Step S205, the SCP performs the analysis according to the called service dialing, obtains the refilled query service category and content, and performs corresponding service operations, and brings the service operation result to the MSC in the service request response message;

Step S206: After receiving the service request response, the MSC sends the service operation result to the BSC, that is, the base station controller, by using the flash request message, and the base station controller forwards the data to the mobile terminal through the base station, where the mobile terminal displays the flash request message. Business operation result information.

In the method of the present invention, the MSC is required to perform correct number analysis on the dialing of the prepaid user, obtain the business operation to be performed by the user, and save it. And can fill in the service request message, and bring the user's service dialing, calling number and other information in the message; for example, if the service is recharged, the dialing should be as follows: X 88 (recharge service code) + card number + password format; In order to query the call charge, it should be in the format of X 99; the MSC is also required to correctly obtain the address of the SCP from the information registered by the terminal user as the destination address, and can send a corresponding message to the SCP corresponding to the address.

In the method of the present invention, after the SCP receives the service request sent by the MSC, the SCP is required to It is correct to dial the user's service and perform corresponding business operations for the business user, including querying the user's account information, or recharging the user account. And the user operation result can be filled in the newly added service request response message and sent to the MSC. After the MSC receives the service request response message, the MSC can extract the text information of the result of the SCP operation from the service request response message according to the ongoing service operation of the user, and place it in the flash request message, and send the message to the mobile terminal through the BSC. .发送 Sending the service operation result to the user by using the flash request message has the characteristics of high real-time response to the user speed, and the amount of data transmitted by the switch is less than the voice data, which is beneficial to reducing the load of the switch.

The method and system for performing service operations on the prepaid user data are as follows. In the technical solution of the present invention, the flow of the service request message and the service request response message between the MSC and the SCP is added, which is existing in the existing In the standard protocol, there is no such process between the MSC and the SCP. At the same time, when the service operation result is returned to the user terminal, the flashing request message of the switch on the MSC network element is utilized, and the service operation result (for example, the queryed charging) is used. Information) transmitting the resulting text information to the terminal via the base station controller BSC and its base station via a flash request message.

Compared with the prior art, the technical solution of the present invention uses the three network elements of the BSC, the MSC, and the SCP to implement the refilling query service, which reduces the implementation complexity of the recharge inquiry service and improves the reliability of the service implementation. Sex, this is because the SMS center and its processing flow are saved compared to the short message method. In the process of performing the service request message, the MSC obtains or sets the user's information from the SCP, and the process is relatively simple; the flash request message is sent to the terminal service. As a result, in response to the high speed of the user's speed, the switch transmits less data than the voice, which helps to reduce the load on the switch.

In the following, the service code *99# of the pre-paid user dialing the inquiry fee is taken as an example, referring to FIG. 3, and is described in detail in conjunction with FIG. 1 and FIG. 2 as follows:

In this embodiment, the specific process for the prepaid user to query the call charge service includes:

Step 301: The terminal user dials the *99# query phone charge service request service code to initiate a call, and the base station controller 101 transmits a call start message to the mobile switching center 102; wherein, *99# is a unique service dialing corresponding to the call charge service. ;

Step 302: When the mobile switching center receives the user's originating message, detecting the calling user's boarding The information includes a call-up smart trigger, and sends a call request message (originationRequest) to the service control point 103. The service control point 103 checks the validity of the user, determines whether the user activates the smart service, and can access the intelligent network. The service request message (originationRequest) is a message in Chapter 5 of the IS-826 protocol, and may also include other fields such as: location ID, service indication, switch number, and the like.

Step 303: The service control point 103 determines that the user activates the prepaid service and the user can perform the service operation, and sends a call origination response message (originationResult) to the mobile switching center to instruct the mobile switching center 102 to continue the call processing.

Step 304: After the mobile switching center 102 receives the call request response message from the service control point 103, the mobile switching center 102 performs number analysis according to the service dialing of the terminal user, and the number analysis result is determined as the service request operation of the recharge inquiry of the terminal user. That is, the parsing of the *99# is performed to obtain a service operation in which the terminal user needs to query the call charge, and then sends a service request message (FeatureRequest) to the service control point 103; the service request message carries information such as the service dialing number and the calling number of the user. For example, if it is a recharge service, the service dialing number is used as follows: X 88 (recharge service code) + card number + password format; if it is for querying the call charge service, the service dial is used in the format of *99#.

Step 305: The service control point 103 performs a corresponding service operation according to the called service dialing. In this embodiment, the service dialing is *99#, indicating that the call charge service is queried, and the service control point 103 performs the query service of the terminal user. And the operation result of querying the call charge service is brought to the mobile switching center 102 in a service request response message (FeatureResult), and the DisplayText is a display text field, and the parameter includes a message length and a message content; the message content is text that needs to be displayed to the mobile terminal. Information, that is, the result of the business operation, such as currency, credit balance, expiration date, etc.;

Step 306: After receiving the service request response, the mobile switching center 102 sends the text content to the base station controller 101 through a flash request message (FlashRequest), and then sends the text content to the terminal user; wherein the text content is placed in the flash request message. In the MS Information Records field, the end user will display information about the text in the flash request.

Further, if the service operation is a recharge service, the dialing service dialing may be dialed, the service dialing plus the card number, the password, and the like are dialed once, and the call request message is sent together, for example, when charging, dial: X 88 ( Assume recharge service code) + card number + password format, but requires service dialing The length is within the range allowed by the switch. The recharged technical solution is somewhat similar to the existing SMS refill method, but does not have to go through the SMS center. After the refilling is completed, the SCP sends a service request response message to send the recharge result information to the MSC, and the MSC sends the flicker request text information to the end user.

In addition, the method of the present invention is also used for a subsequently evolved mobile communication network. For example, the mobile switching center can also be replaced with a mobile switching center server MSC Server, and the base station controller BSC can be replaced with a new generation of BSS systems. Since, in a subsequently evolved network, the technical solution for implementing the method is also within the scope of the claims of the present invention.
