Description

TECHNICAL FIELD The present invention relates to the field of multimedia message communication, and in particular, to a multimedia message timing task processing system and method thereof. BACKGROUND OF THE INVENTION Multimedia Messaging Service (MMS) is a further development of Short Message Service (SMS), which not only supports larger capacity, supports multimedia information content, but also supports more business interaction modes. As the volume of multimedia messaging continues to grow, it will likely become a killer application in the 3G era. There are some tasks in the life cycle of a multimedia message, such as sending a message, resending a message, timeout not getting a forwarded message, expiring a message, and the like. According to the multimedia message service specification (3GPP TS 22.140) and the requirements of the operator, the processing time of these tasks is configurable or user-defined, which is called a timing task of multimedia messages. The processing capability and efficiency of the multimedia message timing task directly affects the user experience and the economic benefits of the operator, and is an important part of the processing capability of the multimedia message center (MMSC). The existing multimedia message timing task processing technology adopts a full table scan processing method. The specific method is as follows: A fixed processing time slot is allocated in the message processing module (MESG), triggered by the system's second timer, and a full table scan is performed on the multimedia message control information table of the database module (DB), and the check is found to satisfy the trigger. The message of the time condition is processed according to the corresponding task; when the scanning time exceeds the specified processing time slot, the scanning is stopped, and the next second timer is triggered to trigger. The main disadvantages of this processing mode are low processing efficiency, poor real-time performance, and insufficient and flexible expansion of the timing task function. The reasons are as follows: First, because there is no way to know whether there is a scheduled task at the current time, it can only rely on the fixed time slot allocated in the message processing module. Table scan, which causes instantaneous external request signaling blocking, especially when the traffic is busy, causing the external request signaling response to time out, resulting in a decrease in system processing success rate. Second, a medium-sized MMSC has a message storage capacity of one million. Above the level, the second timer needs multiple triggers to complete the full table scan, so the real-time performance of the timing task is greatly reduced. In addition, the prior art does not distinguish between messages and message related tasks, and does not provide a complete and flexible management method for timing tasks. Therefore, there is a need for a system and method for the complete management of multimedia message timing tasks and for efficient, high real-time processing. SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a system for efficiently and highly real-time processing of multimedia message timing tasks based on MMSC.

The message processing module extracts the control information from the database module according to the received control time key according to the received timing task, and then processes the timing task by using the control information. In the system of the present invention, under certain conditions, the message processing module actively sends the timing task deletion signaling to the timed task management module, and the timed task management module calculates the second queue to which the timed task belongs according to the second queue mapping algorithm, in the corresponding second queue. Delete the timed task. In the above system, the timing task information includes a trigger time, a task type, and a control information primary key. In the above system, the system support module sends the second timer signaling to the timed task manager every second.

FIG. 2 is a schematic structural diagram of a system 200 of a multimedia message timing task processing system according to the present invention. The figure is also a system structure diagram of the processing module 102-4, and the multimedia message timing task processing system is shown in detail. The structure of 200 and the relationship between the internal modules. As shown in FIG. 2, the multimedia message timing task processing system 200 includes a message processing module (MESG) 202, a database module (DB) 204, and a timed task management module (TASK) 206. The MESG 202 is configured to receive signaling, invoke a database module interface and a timed task management module interface, and complete a process of processing the message. When the received signaling is a message submission signaling, the control information is stored in the DB 204, and the timing task is performed. Stored to TASK 206.

The DB 204 is configured to store the control information, and return the automatic generation control information primary key as the response information to the MESG 202, and the MESG 202 can acquire the control information from the DB 204 according to the control information primary key. The TASK 206 is used to store and trigger the timing task. The MESG 202 extracts the timing task information from the control information and stores it to the TASK 206. The TASK 206 triggers the timing task to the MESG 202 to request processing according to the specified time. The timed task information includes: trigger time, task type, and control information primary key. The trigger time is the execution time, in seconds, at which the task is specified at the time of the specified time. The task type refers to various types of timed tasks of the multimedia message, including timed sending, timed retransmission, timeout not obtained forwarding, message expiration, etc., and can be extended according to the service. The timing task establishes association with specific control information through the control information primary key. The TASK 206 stores the scheduled tasks of the same second trigger time in the same second queue, and the data storage space of the TASK 206 is composed of such a set of second queues. Through the second queue mapping algorithm, it can be determined in which second queue the scheduled task is stored. In addition, the multimedia message timing task processing system 200 further includes a system support module (VOS) 208 for providing timers required for the multimedia message timing task processing system and providing underlying communication between the modules. The module functions and interfaces in Figure 2 are described in Table 2 below. Table 2 Module Name Function and Interface System Support Module is responsible for providing the underlying communication between modules and providing the system.

(VOS) 208 200 required timer. Timing task management module in Figure 2

206 The received second timer is the loop timer issued by the system support module 208 according to the system configuration. The message processing module is the control core of SERVER 102-4. It is responsible for the control and processing of the MESG 202 paired message flow. It calls the database module interface and the timed task management module interface. It not only has to be connected The real-time signaling sent by the RELAY 102-2 is processed, and the timing task triggering signaling (TriggerTaskReq) sent by the processing time task management module 206 is also received. The database module is responsible for storing control information of the multimedia message, generally by

(DB) 204 Large commercial database. The scheduled task management is responsible for the scheduled task management of multimedia messages. The real module (TASK) 206 is now fully scheduled for task management, including insertion, triggering, and deletion. The data storage space inside the module consists of an array of seconds queues. In addition, the present invention provides a method for processing a multimedia message timing task, comprising the steps of: controlling information processing steps, the message processing module (MESG) 202 receives the message submission signaling, and stores the control information to the database module (DB) 204. And obtaining a control information primary key; in the subsequent signaling processing of the message, extracting control information from the DB 204 according to the control information primary key for message processing; and timing task management step, the timed task management module (TASK) 206 storing the timed task And triggering, wherein the MESG 202 extracts the timing task information from the control information and stores it to the TASK 206, and the TASK 206 triggers the timing task to the MESG 202 to request processing according to the specified time. The method of operation of the corresponding signaling between embodied as three modules: a timing task into signaling (InsertTaskReq), the timing task trigger signaling (TriggerTaskReq), and a timing task is removed Signaling (DeleteTaskReq) ₀

A. The steps to insert are as follows:

Upon receiving the multimedia message submission signaling, the MESG 202 stores the control information in the DB 204, and the DB 204 returns the control information primary key. Then, the MESG 202 extracts each timing task required information from the control information, and sends it to the TASK 206 through the InsertTaskReq, thereby completing the stripping of the timing task. Based on the second queue mapping algorithm, the TASK 206 calculates a second queue to which the scheduled task belongs, and adds the scheduled task to the end of the queue of the corresponding second queue.

B. The steps to trigger are as follows: Depending on the system configuration, VOS 208 sends a second timer to TASK 206 every second. After receiving the second timer, the TASK 206 calculates the second queue corresponding to the current time of the system according to the second queue mapping algorithm, and the timing task in the second queue is sequentially sent to the MESG 202 through the TriggerTaskReq, and the scheduled task is deleted from the second queue after being sent. Continue processing the next scheduled task until the second queue is empty, and the exit processing waits for the next second timer.

The MESG 202 extracts the control information from the DB 204 according to the control information primary key in the received timed task, and then uses the control information to complete the message processing required by the task type in the scheduled task.

C. The deleted step silver is as follows: Under certain conditions, for example, when the message has been successfully acquired within the validity period or the user refuses, the timed task of the message expiration needs to be deleted, so as to prevent the timing task from triggering the expiration processing of the message, and the MESG 202 actively sends the DeleteTaskReq. Give TASK 206.

Based on the second queue mapping algorithm, the TASK 206 calculates the second queue to which the scheduled task belongs, and deletes the scheduled task in the corresponding queue.

2. Timing task management: ^ internal structure and external interface Figure 3 is the storage structure and interface diagram of the timed task management module. The following is a detailed description of the internal storage structure and external interface of the timing task management.

The storage structure of TASK 206 internal data is defined as follows: The default value of the validity period of the multimedia message in the current implementation is 48 hours. Considering some exception protection, the message has The maximum value of the effect value is set to 50 hours, so the data storage space of TASK 206 is composed of 180,000 (50 x 3600, which is the maximum number of seconds of the message) second queue array, the required storage capacity and system requirements. The traffic of the message service is directly proportional, and the traffic of 200 bits/second requires 200M of data storage space. The second queue mapping algorithm is: Second Queue Array Position = Trigger Time MOD 180000 The trigger time is UNIX time, which is the number of seconds since 1970. MOD is a modulo operation, and the time is looped back by modulo, so that the finite-second queue array resource in TASK 206 is used repeatedly. The length of the queue in the header node of the second queue ( length ) describes the number of scheduled tasks for the current second queue.

TASK 206 has three external interfaces: insert, trigger, delete; three interfaces are embodied as three signaling interactions with MESG 202: timing task insertion signaling (InsertTaskReq), timing task trigger signaling (TriggerTaskReq), timing task deletion letter Order (DeleteTaskReq). Each signaling contains three fields: trigger time, task type, and control information primary key. Insertion action: caused by the timing task insertion signaling (InsertTaskReq) sent by the message processing module (MESG) 202, the timed task management module (TASK) 206 receives the post-secondary queue mapping algorithm, and calculates the second queue to which the scheduled task belongs. , insert the timed task into the end of the queue of the corresponding second queue, then increase length by 1. The triggering action is caused by the second timer signaling sent by the system support module (VOS) 208. The timed task management module (TASK) 206 receives the second queue that needs to be triggered by the current time according to the second queue mapping algorithm. If the second queue length to be triggered is 0, the processing is directly exited. If the second queue length to be triggered is not 0, it is sent to the message processing module (MESG) 202 through the timing task trigger signaling (TriggerTaskReq) in the order of first in first out (FIFO), and the timed task is cleared immediately after being sent out, and the length is reduced. 1 , until length is 0, the queue message is processed and then exit processing, and then wait for the next second timer to arrive. Deletion action: caused by the timed task deletion signaling (DeletaTaskReq) sent by the message processing module (MESG) 202. After the timed task management module (TASK) 206 receives the second queue mapping algorithm, the second queue to which the scheduled task belongs is calculated. . If the owned second queue length is 0, the processing is directly exited. If the owned second queue length is not 0, the second queue is scanned. If the timing task is found, the second queue is then decremented by 1 from the second queue. If not found, the processing is directly exited.

3. Typical business process Each multimedia message has a timing task, including: The sender can set the time of sending the message, and can customize the validity period of the message; The operator can set the default message validity period, set the timeout, and not obtain other systems for forwarding. The time (currently China Mobile is forwarding DreamWorks album, China Telecom is forwarding e-mail), and the message of failed transmission is scheduled to be retransmitted according to the time policy. It can be seen that by scanning the message table to check so many conditions, the system efficiency cannot be improved. The core idea of the present invention is to separate the timing task of the multimedia message from the control information of the multimedia message, and establish an independent and complete timing task management mechanism. 4 is a typical service flow diagram of a multimedia message timing task processing system according to an embodiment of the present invention, and describes a service process for transmitting multimedia messages point-to-point between two mobile phone terminals belonging to the same MMSC. In order to more clearly illustrate the key processing flow and the stripping method of the timing task, only the processing of the timing tasks of the timing transmission and the message expiration is described, and the triggering time of the timing task is described in detail. The maximum system validity period of the MMSC is set to 60 hours. The multimedia message terminal-to-terminal service processing includes four processes of submitting, annotating, acquiring, and delivering a report. As shown in FIG. 4, the specific processing flow is as follows: Step 1: August 1, 2006, 22: 00, mobile phone A to mobile phone B A multimedia message (message Mm) is sent, and the message delivery time is 8:00 on August 2, 2006, and the validity period is 24 hours, and 4 advertisements are required to be delivered; the mobile phone A is immediately submitted to the MMSC exchange module through MMl_submit.REQ ( RELAY ) 102-2. Step 2: RELAY 102-2 receives the message, the message content storage media (MmContent), generate a message identifier, and message submission back to handset A successful response signaling (MMl_submit.RES) ₀ MmContent In implementations because relatively large, So it is stored in the magnetic array as a file. Step Green 3: RELAY 102-2 then extracts the control information of the message (MmCtrllnfo), and the control information contains key information of the message, such as message processing status, MmContent storage location, message expiration time, etc., and is sent by internal submission signaling (MM2SubmitReq) MESG module 202 of SERVER 102-4. This achieves the separation of multimedia message media content (MmContent) and control information (MmCtrlInfo). Step 4: The MESG 202 receives the control information and saves the control information to the DB 204 through the database insertion interface. In the implementation, the control information is stored in the multimedia message control information table of the database in a recording manner. Step 5: The DB 204 automatically generates and returns the control information primary key so that the control information is saved in the database. The MESG 202 checks the control information, and finds that the message is a timed transmission message, and the validity period is 24 hours. Then, the timing task insertion signaling (InsertTaskReq), the timing sending (taskl), the message expiration (task2), and the corresponding triggering are performed. The time, and the above control information primary key are sent to the TASK 206. This further separates the multimedia message control information (MmCtrlInfo) from the multimedia message timing task (MmTasklnfo). Step 6: The TASK 206 receives the scheduled task, and firstly calculates the second queue of the scheduled transmission at 8:00:00 on August 2, 2006 by the second queue mapping algorithm: 1154476800 MOD 180000 = 136800, the taskl saves the chase 136800 seconds queue queue tail; then calculate the second queue of the expired message belonging to August 2, 2006 at 22: 00: 00: 1154613600 MOD 180000 = 93600, save task2 to append the 96000 second queue queue tail. Step 7: Every second TASK 206 will receive the second timer sent by VOS. When the time is 8:00:00 on August 2, 2006, TASK 206 will send out the 136800 second queue processing, which will trigger taskl. (TriggerTaskReq) to MESG 202. Because only one second queue is processed in one second, the retrieval efficiency and real-time of the timing message are guaranteed. Step 8: Upon receiving the taskl, the MESG 202 first needs to obtain the control information, and then calls the database query interface to obtain the control information by controlling the primary key of the information in the scheduled task information. The timed task is to establish contact with the control information through the control information primary key. Step 9: The DB 204 retrieves the control information from the database and returns it to the MESG 202. Step 10: Because the task type in the task1 timing task information is sent periodically, the MESG 202 composes the notification according to the extracted control information, such as the control information primary key, the source destination mobile phone number, etc., and requests the RELAY 102 through the internal lower notification signaling (MM2NotificationReq). 2 issued a notice. Step 11: RELAY 102-2 sends a notification (MMl_Notification.REQ) to mobile phone B via WAP. Step - Step 12: Phone B returns an announcement response (MM1 - notification.RES). Step 13: If the mobile phone B requests the acquisition of the message in time after receiving the notification, it will send the acquisition request signaling (MMl retrieve.REQ) to the RELAY 102-2. Step 14: The MMSC delivers the message to the handset B (MMl_retrieve.RES). Step 15: The mobile phone B obtains the message successfully, and informs the MMSC by acquiring the acknowledgement signaling (MMl_acknowledge.REQ). Step 16: RELAY 102-2 sends an internal acquisition confirmation signaling (MM2AcknowledgeReq) to the MESG 202 of SERVER 102-4, which contains the control information primary key. Step 17: After receiving the MESG 202, it is first necessary to change the processing status of the message, and then call the database query interface again to obtain the control information. Step 18: The DB 204 retrieves the control information from the database according to the control information primary key, and returns to the MESG 202. Step 19: If the message has been successfully acquired, the expiration processing will not be performed again, and the MESG 202 needs to delete the task2. The MESG 202 sends the message expiration time from the control information to the TASK 206. The TASK 206 calculates the second queue to which the task2 belongs according to the expiration time of August 3, 曰22: 00: 00. : 1154613600 MOD 180000 = 93600 , look up from the beginning to the end in the 93600 second queue team, delete the task2 after the discovery, so that the timed task of the expired message will never be triggered again, avoiding the repeated processing and charging of the message. Single conflict. If the message has expired at this time, skip this step. Step-like 20: MESG 202 CDR, migrates the message state to the termination state, and updates the database. Step 21: The MESG 202 requests the RELAY 102-2 to send a delivery advertisement to the source user through the internal delivery report request signaling (MM2DeliveryRptReq). Step 22: The RELAY 102-2 sends the delivery notification to the mobile phone A by means of the delivery request notification signaling (MMl_DeliveryReport.REQ), so that the source user knows whether the mobile phone B receives the message, and the message flow is completed. Step 23: This step only occurs when the abnormality of the mobile phone B has not been obtained, that is, it jumps directly from step 11 to step 23. This may be because the terminal is shut down, the terminal does not support, etc., which is in the actual situation. About 30% of the traffic, it needs to be expired; the current time reaches August 3, 2006 at 22: 00: 00, triggered by the second timer, TASK 206 takes out the 93600 second queue processing, will task2 The trigger (TriggerTaskReq) is sent to the MESG 202. Next, 3 megabytes is returned to step 17 to continue execution, that is, steps 17, 18, 20, 21, 22 are completed, and the message processing ends. According to the above steps, based on the separation of the multimedia message media content and the control information, the secondary separation of the multimedia message control information and the multimedia message timing task is further realized. This not only improves the processing efficiency of the system, but also makes the system very flexible for the expansion of the timing task function. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
