Abstract

A method for processing value added service request, which is applied to multimedia message service system that including MMSC and VASP, and the method includes: MMSC receives multimedia message that is send to VASP by outside entity, obtains the value added service identification information corresponding to multimedia message according to the identification number in the multimedia message, creates a delivering multimedia message request that comprises multimedia message and value added service identification information, and sends the request to VASP. After VASP has received the delivering multimedia message request, the VASP sends the multimedia message in the delivering request to the value added service processing module corresponding to the value added service identification information according to value added service identification information in the delivering multimedia message request. The present invention can know indirectly which value added service of which VASP is interacting with the outside entity, and avoid VASP setting different receiving interfaces for different value added service or adding new mechanism in order to identify value added service.

Description

Technical field

The present invention relates to Multimedia Messaging Service (MMS), and more particularly to a method of processing a value added service request. Background of the invention

The current multimedia messaging service system can provide users with a variety of value-added services through multimedia messaging services. These value-added services can be provided by a value-added service provider (VASP) to enable multimedia information transfer between the user terminal and the Internet. The Multimedia Message Service Center (MMSC) is the core of the entire multimedia messaging service system and is responsible for storing and processing multimedia messages. The interface between MMSC and VASP is defined as the MM7 interface in the 3GPP standard and is implemented based on IP. Any service provider (SP) can access the MMSC as long as it supports the MM7 interface, thus becoming a straightening service provider for multimedia messaging services, providing value-added services for end users, such as information, game comics, and earprints. Wait.

The multimedia information interaction between the user and the VASP includes such an application: The external entity actively sends a multimedia message to the VASP. These external entities may be MMS terminals, . Bud application or other external multimedia business system. Regardless of the external entity of the county, the message interaction between these external entities and the VASP is handled by the MMSC, and the processing mechanism is the same for the MMSC. Therefore, for the convenience of description, the following takes the external entity as the MMS terminal as an example to illustrate the process of the external entity actively sending multimedia messages to the VASP.

As shown in FIG. 1, the MMS terminal sends a multimedia message to the VASP fishing process including the following steps:

Step 101: The MMS terminal sends a submit message (MM1_submit.REQ) to the MMSC. The submission message contains the access number of the recipient VASP.

Step 102: After receiving the MM1_submit.REQ message, the MMSC verifies the access number of the receiving party VASP included in the MMSC.

Step 103: The MMSC returns a submit message response (MM1_submit.RES) to the MMS terminal. If the VASP access number is successfully verified, the MM1_submissionRES message includes information that has been successfully received and will process the submitted message; otherwise, MMl_submitRES The message contains hunting error information.

Step 104: The MMSC sends a transmission request message (MM7_Deliver.REQ) to the VASP, where the MM7_Deliver.REQ message includes a multimedia message. In practical applications, the MM7-Deliver.REQ message is generally received and processed by the value-added service processing module in the VASP.

Step 105: After receiving the MM7-deliver.REQ message, the VASP returns a transmission request message response (MM7-Deliver.RES) to the MMSC.

In the above solution, after receiving the MMl-submit.REQ message sent by the MMS terminal, the MMSC searches for the uplink U L address of the received message according to the access number, and then forwards the MM7-Deliver.REQ message according to the found uplink URL address. For example, the MMSC includes a correspondence table between the pre-established VASP access number suffix and the uplink URL address, and the MMSC can search for the correspondence between the access number prefix and the uplink URL address according to the access number prefix in the MM1-submitREQ message. The table obtains the uplink URL address of the received message, that is, the corresponding value/interface address corresponding to the currently interacting value-added service, and then sends the MM7_Deliver.REQ message to the queried when the MMSC sends the MM7_Deliver.REQ message to the VASP. The interface address goes. After receiving the MM7-Deliver.REQ message forwarded by the MMSC, the receiving interface of the VASP directly processes the multimedia message.

Because the VASP in the prior art distinguishes different services by using different interface addresses, it is necessary to establish more receiving interfaces, and different receiving interfaces receive and process different value-added services, which leads to inconvenient program development and increases VASP. Handling complexity. In addition, Since each receiving interface processes the received multimedia message by using the corresponding value-added service processing module, the programs of the plurality of value-added service processing modules may be the same, thereby causing the design of the processing program to be repeated and causing waste of resources. When VASP only establishes a receiving interface, if VASP operates multiple value-added services, VASP cannot judge which value-added service each transmitting request message is related to. Therefore, VASP needs to add another mechanism to parse the multimedia message to find the corresponding Value-added services. Summary of the invention

In view of this, the main object of the present invention is to provide a simple and effective processing method for value-added service requests, which enables VASP to operate multiple value-added services without establishing multiple receiving interfaces.

In order to achieve the above object, the extraction protocol of the present invention is implemented as follows:

The invention discloses a processing method for value-added service clearing, which is applicable to a multimedia message service system including at least MMSC and VASP, and the method comprises the following steps:

A. The MMSC receives the multimedia message sent by the external entity to the VASP, obtains the value-added service identification information corresponding to the multimedia message according to the identification number in the multimedia message, generates a multimedia message transmission request including the multimedia message and the value-added service identification information, and sends the message to the VASP. ;

After receiving the multimedia message transmission request, the VASP sends the multimedia message in the transmission request to the value-added service processing module corresponding to the value-added service identification information according to the value-added service identification information in the multimedia message transmission request.

In the step A, the method for obtaining the value-added service identification information corresponding to the multimedia information may be: the MMSC searches for the corresponding number segment in the identification number and the value-added service identification information according to the specified number segment in the identification number. The VASP registration information table of the relationship finds the value-added service identification information corresponding to the specified number segment in the identification number. Or, in the step A, the method for obtaining the value-added service identification information corresponding to the multimedia message may be: the MMSC parses the specified number segment in the identification number, and uses the specified number segment in the identification number as the value-added service target-identification information. . The specified number segment in the identification number may be a prefix of the identification number, or an intermediate 殳, or an ending segment.

In the above solution, the step B includes: the VASP reads the value-added service identification information in the multimedia message transmission request, determines the value-added service according to the value-added service tag information, and determines the 3 value-valued service process for processing the current multimedia message according to the determined value-added service. The module sends the multimedia message to the determined value-added service processing module.

The value-added service identification information may be a value-added service code (VASID).

In addition, the value-added service identifier may further include a value-added service provider code (VASPID). In step B, the sending the multimedia message to the value-added service processing module includes: verifying the VASPID in the multimedia message transmission request, if the verification If successful, the multimedia message is sent to the value-added service processing module corresponding to the VASID; otherwise, the process ends.

In the foregoing solution, before the obtaining the value-added service identifier information corresponding to the multimedia message, the method further includes: verifying the label, identifying the number, and determining whether the verification is successful. If the verification is successful, returning the success message to the external entity, and continuing; otherwise , return the failure information to the external entity, and end the process. The identification number may be an access number of the VASP.

The method for implementing the value-added service interaction of the VASP provided by the present invention can directly learn which VAS value-added service interacts with the external entity by transmitting the value-added service identification information in the request, thereby preventing the VASP from setting different value-added services. Different receiving interfaces reduce program design complexity and save system resources; and also reduce the VSAP to add new mechanisms for identifying value-added services. That is, VASP does not need to add another complex mechanism to parse multimedia messages, such as through parsing. The specific message content in the message identifies the complex mechanism of the value-added service, thus also speeding up the information interaction between the VASP and the MMSC. BRIEF DESCRIPTION OF THE DRAWINGS

1 is a schematic diagram of a process in which an MMS terminal sends a multimedia message to a VASP; FIG. 2 is a flowchart of a method for processing a value-added service request according to an embodiment of the present invention. Mode for carrying out the invention

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The main idea of the present invention is to determine which value-added service the current multimedia message interacts with by using the field of the value-added service provider code and the value-added service code extended in the request message, and then handing the multimedia message to the corresponding value-added service processing module. deal with.

As shown in FIG. 2, a method for processing a value-added service request according to an embodiment of the present invention includes the following steps:

Step 201: The MMS terminal sends a submit message (MM1_submit.REQ) to the MMSC, where the submit message includes the access number of the recipient VASP.

Steps 202 ~ 203, after receiving the MMl-submit.REQ message, the MMSC verifies the access number of the VASP, and returns a submit message response (MMl_submit.RES) to the MMS terminal. If the verification succeeds, the MM 1 - The submit.RES message has successfully received and will process the information of the submitted message, and proceeds to step 204; No MM 1 - submit. RES message contains error information, and the process ends.

The above steps 201, 202 and 203 are the same as those of the prior art steps 101 to 103.

Step 204: Perform value-added service matching, and generate a transmission request (MM7-deliver.REQ) message including value-added service identification information.

The step 204 may specifically include: the MMSC searches for the received uplink UL address according to the access number, and searches for the information identifying the currently value-added service, which is called the 3⁄4 value service identification information, and then the found value-added service identifier information. Add force MM7-deliver.REQ eliminates, ^, and then according to the found upstream URL address 3 boast the MM7-deliver.REQ forward iij go.

In this embodiment, the value-added service identifier information may be a value-added service code (VASID) corresponding to the value-added service, or may be a value-added service provider code (VASPID) and a VASID corresponding to the value-added service, or may be based on actual conditions. The operator uses other parameters as value-added service identification information.

The following describes the VASPID and VASID as value-added service identification information. For example, the access number prefix in the MM1-submit.REQ message submitted by the MMS terminal may be the VASPID and VASID of the actual recipient VASP, and the MMSC may decrypt the access number prefix in the MMl_submit.REQ, directly receiving The VASPID and VASID of the VASP are then added to the MM7-deliver.REQ message. For example, the access number is "888800100Γ, where the access number prefix is "888800", "8888" corresponds to VASPID, and "001" corresponds to VASID.

Alternatively, an established VASP registration information table may be pre-set, including a correspondence between the specified number segment in the identification number and the value-added service identification information, where P is an MMl_submit.REQ message, an access number prefix in the The correspondence between the VASPID and VASID of each registered VASP. In this way, the MMSC can first decompose the access number prefix in the MMl_submit.REQ message, and then look up the SP registration information table in the MMSC to obtain the VASP ID and VASID of the VASP, that is, obtain the value-added service identification information. The access number prefix generally refers to a number segment of the specified "^ degree" at the beginning of the access number, such as the first seven digits in the previous example.

In the above solution, the VASP access number prefix is used to distinguish the service type. In practice, the ^^ can be replaced by other specified number segments, such as the middle or end segment of the access number, or other specified number segments. The intermediate segment of the access number may be a segment number limited by a specified start bit and a final J bit. Step 205: Send a generated 々MM7-deliver.REQ message to the VASP.

Step 206, VASP ^: After the MM7-deliver.REQ message, return a request message response (MM7-Deliver.RES) to the MMSC.

The above steps 205, 206 are the same as those of the background art steps 104, 105. Step 207: The VASP reads the value-added service identifier information in the MM7-Deliver.REQ message, and determines the value-added service processing module corresponding to the current value-added service according to the value-added service identification information, and then sends the MN 7-Deliver.REQ message. The multimedia message is handed over to the value-added service processing module of the correct t for processing.

As described above, if the VASPID and VASID of the value-added service are used as the value-added service identification information, in this step, the VASP can first verify whether the VASPID in the MM7-deliver.REQ message is the same as the VASP ID of the VASP itself. If the VASPID in the message is the same as the VASPID of the VASP, the verification is successful; otherwise, the verification fails. If the VASPID verification result is a failure, the bundle process; if the face certificate result is successful, the VASID corresponding to the VASID is determined according to the VASID of the message, and then the VASID carries the code, and the saved value-added service processing module and the VASID are saved. The corresponding relationship between the two is to find a value-added service processing module corresponding to the value-added service. If only the VASID of the value-added service is used as the service identification information, the value-added service processing module corresponding to the VASID is found according to the correspondence between the value-added service processing module and the VASID.

In the above embodiment, the access number is used to distinguish the type of service requested when the user sends the multimedia message, but in actual applications, other identification numbers may be used instead of the access number.

The method provided by the present invention can directly know which VAS value-added service the external entity interacts with, so as to prevent the VASP from setting different receiving interfaces for different enhanced services, and the VASP does not need to add another Complex mechanisms to solve multimedia messages, and therefore also facilitate the information interaction between VASP and MMSC.

In summary, the above is only the preferred embodiment of the present invention and is not intended to limit the present invention. It is to be understood that any modifications, equivalent substitutions, improvements, etc., made within the spirit and scope of the invention are intended to be included within the scope of the invention.
