Description

The present invention relates to the field of communications, and in particular to a Multimedia Messaging Service Center (MMSC) and a method for delivering a message. BACKGROUND A Multimedia Messaging Service (MMS) is a type of communication between different mobile terminals (eg, mobile phones), between service providers and mobile terminals, and between other applications such as mobile terminals and email servers. A messaging service that delivers multimedia content. The multimedia messaging service has been widely carried out at present, especially the rich, timely and fast service provided by the service provider for mobile phone users, enriching the life of the user. 1 is a flowchart of a message sent in a multimedia message service in the related art. As shown in FIG. 1 , the following steps are included: Step 4: 101: The MMSC service module generates a delivery message (hereinafter also referred to as a message to be sent). Sending the sent message to the MMSC codec module; wherein, the MMSC service module is a module for processing the service flow by the MMSC, different messages are generated in different links, and an announcement message is generated in the notification sending session, if the final state of the message is sent to the mobile terminal The obtaining link generates a user delivery message, wherein the message is sent by the announcement message and the user delivers the message, and both messages are short messages, which are sent by the Short Message Service Center (SMSC). To the mobile terminal (UA), wherein the MMSC codec module is configured to encode the received internal message into a short message to a short message, and then send it to the SMSC, and After receiving the response of the SMSC, decoding is performed according to the SMPP protocol, and converted into an internal message; Step 102: The MMSC codec module receives the service module. The encoded message sent by the SMSC SMPP protocol, the message is sent to the SMSC SUBMIT_SM; Step 103: The SMSC receives the submit_sm message of the MMSC, and returns a response submit sm resp to the MMSC. After receiving the response message returned by the SMSC, the MMSC codec module decodes the message into the MMSC internal message according to the SMPP protocol. Step 4: 104, SMSC Send text messages to users. Step 4 and 103 can be performed simultaneously. In the related art, the message delivery process is repeatedly performed, and the MMSC codec module immediately encodes and delivers the message after receiving the service delivery message. For some services (for example, mobile phone reporting service, SP group sending platform), the number of destination addresses is large, and the sending time is long. When the delivery message received by the service generates an instantaneous peak, it will inevitably cause an instant moment to the SMSC. The impact caused the SMSC to exceed the processing capacity of the SMSC in a short period of time, resulting in the message not being processed normally. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a multimedia message center and a method for delivering a message to solve the above problem. An aspect of the present invention provides an MMSC, including: a service module, a codec module, and a cache processing module, where a service module is configured to send a message to be sent to a cache processing module; and a cache processing module is configured to cache Sending a message, and sending a buffered message to be sent to the codec module according to the rate that the SMSC can process; the codec module is configured to encode the to-be-sent message received from the cache processing module, and encode the to-be-sent message Issued to the SMSC. The cache processing module controls the rate at which the message is sent by sending a message to be sent in a scheduling period, where the SMSC can process the rate=transmission threshold/scheduling period. The cache processing module controls the start of each scheduling period by using a timer message, where the timer message is triggered at the beginning of each scheduling period. The cache processing module includes: a receiving module, configured to receive a message to be sent from the service module, and a determining module, configured to determine whether the current sending rate reaches a rate that the SMSC can process; and the scheduling module is configured to determine in the determining module If the result is YES, the scheduling cache processing module and the first sending module, in the case that the determining result of the determining module is negative, scheduling the second sending module; the cache processing module, configured to buffer the receiving module to receive the sending Message; first delivery module, for The to-be-sent message buffered by the cache processing module is sent to the codec module according to the rate that the SMSC can process. The second sending module is configured to directly send the uncached to-be-sent message to the codec module. The scheduling module is further configured to: when the cache processing module fails to cache, schedule the second sending module; the second sending module is further configured to send, to the codec module, the buffered to-be-sent message. Another aspect of the present invention provides a method for sending a message, including: the MMSC generates a to-be-sent message; the MMSC buffers the to-be-sent message, and selects a to-be-sent message from the buffered to-be-sent message according to a rate that the SMSC can process; The selected to-be-sent message is encoded, and the encoded to-be-sent message is sent to the SMSC. The MMSC controls the rate at which the message is sent by selecting a number of to-be-sent messages that are sent by the sending threshold in a scheduling period, where the rate that the SMSC can process = the sending threshold/scheduling period. The MMSC controls the start of the scheduling period by using a timer message, where the timer message is triggered at the beginning of each scheduling period. Before the MMSC caches the to-be-sent message, the method further includes: determining whether the current delivery rate reaches a rate that the SMSC can process, and if yes, continuing the subsequent processing; otherwise, directly encoding the uncached to-be-sent message, after encoding The to-be-sent message is sent to the SMSC. If the buffer to be sent is cached, the message to be sent that is buffered is directly encoded, and the encoded message to be sent is sent to the SMSC. The rate that the SMSC can process is dynamically determined by the current processing capability of the SMSC. The rate that the SMSC can process is determined by: the MMSC obtains the current processing capability information of the SMSC in real time or periodically, and determines the SMSC according to the processing capability information. The rate of processing; or, the SMSC feeds back to the MMSC when its processing capability information changes to 4, and the MMSC determines the rate that the SMSC can process according to the processing capability information. The invention adds a buffer processing module between the service module and the codec module of the MMSC, and the module sends the message to be sent to the codec module according to the speed that the SMSC can process, and solves the problem that the SMSC exceeds the processing in a short time in the related art.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. The present embodiment provides an MMSC. FIG. 2 is a structural block diagram of an MMSC according to an embodiment of the present invention. The MMSC includes: a service module 22, a codec module 26, and a cache processing module 24, and a service module 22 for The to-be-sent message (the message to be sent may be an advertisement message or a user-delivered message) is sent to the cache processing module 24; the cache processing module 24 is configured to buffer the message to be sent, and to the codec module 26 according to the rate that the SMSC can process. The to-be-sent message is sent to the SMSC. The codec module 26 is configured to encode the to-be-sent message received from the cache processing module 24, and send the encoded to-be-sent message to the SMSC. The MMSC in this embodiment caches the to-be-sent message of the service module 22 by adding the cache processing module 24, and sends the to-be-sent message to the codec module 26 for encoding according to the rate that the SMSC can process, and changes the service in the related art. The module 22 generates a message to be sent and sends it to the codec module 26 for encoding and then sends the message to the SMSC. The method for limiting the delivery of the message is limited, and the short-time traffic of the SMSC exceeds the processing capability in the related art. The problem that the message cannot be processed normally avoids the instant impact on the SMS center when the multimedia message center business surges, which can lower the performance requirements of the SMS center and improve the business success rate. It should be noted that the rate that can be processed by the foregoing SMSC may be a fixed rate or a changed rate, where the fixed rate may be a preset value according to actual operating conditions of the system; the rate of change may be The specific change strategy can be pre-configured as time period changes, or as the current processing power of the SMSC changes dynamically. In the case that the message sending rate dynamically changes with the current processing capability of the SMSC, the MMSC can obtain the current processing capability information of the SMSC in real time or periodically, and then determine the current message sending rate according to the information, or may be the SMSC. The MMSC feeds back to the MMSC when the processing capability information changes, and the MMSC determines the current message delivery rate based on the information. For the control of the sending rate, for the sake of brevity, the cache processing module 24 can control the rate at which the message is sent by sending a number of messages to be sent in a scheduling period, where the rate that the SMSC can process = Send threshold/scheduling period. It is very convenient to process in this way, and the accuracy of the rate control can be adjusted by selecting different scheduling periods. The smaller the scheduling period is selected, the higher the accuracy of the rate control, and the smoother the rate of message delivery. During the process of rate control by the cache processing module 24, the current time can be scanned at any time to check whether the current scheduling period has ended, and whether a new scheduling period should be started. The implementation of this method is relatively straightforward, but may be performed on the cache processing module. The resource is more expensive. Therefore, in order to facilitate the processing of the cache processing module 24, the cache processing module 24 can control the start of the scheduling period by using a timer message, wherein the timer message is triggered at the beginning of each scheduling period. In such a processing manner, the cache processing module 24 can restart a scheduling period when receiving the timer message, without determining whether to restart a scheduling period by using a scan at any time, and occupying a small system resource. And easy to manage. FIG. 3 is a block diagram of a preferred structure of an MMSC according to an embodiment of the present invention. As shown in FIG. 3, the cache processing module 24 may include: The receiving module 30 is configured to receive a message to be sent from the service module 22, and the determining module 31 is coupled to the receiving module 30, configured to determine whether the current sending rate reaches a rate that the SMSC can process; the scheduling module 32 is coupled to the determining module. 31. For the case that the determination result of the determination module 31 is YES, the scheduling cache processing module 33 and the first sending module 34, if the determination result of the determining module 31 is negative, scheduling the second sending module 35 The cache processing module 33 is coupled to the service module 22 and the scheduling module 32 for buffering the to-be-sent message received by the receiving module 30. The first sending module 34 is coupled to the buffer processing module 33 for processing according to the rate that the SMSC can process. The to-be-sent message cached by the cache processing module 33 is sent to the codec module 26; the second delivery module 35 is coupled to the service module 22 and the scheduling module 32, and is configured to directly send the uncached to-be-sent message to the codec module. 26. The judgment of the above-mentioned judging module 31, if the current rate has not reached the rate that the SMSC can process, the message to be sent received by the receiving module 30 is directly sent to the codec module 26 through the second sending module 35, reducing The caching link improves the processing performance of the system. Preferably, the scheduling module 32 is further configured to: when the cache processing module 33 fails to cache, schedule the second sending module 35; the second sending module 35 is further configured to send the buffered failed to send message to the codec module 26 . By adding a branch of the error processing to the scheduling module 32, in the case that the cache processing module 33 fails to cache, the buffered to-be-sent message is directly sent to the codec module 26 through the second sending module 35, thereby preventing the cache failure. The resulting message is lost, which improves the stability of the system. 4 is a flowchart of a method for sending a message according to an embodiment of the present invention. The method includes: Step S402: The MMSC generates a message to be sent; Step S404, the MMSC buffers a message to be sent, and according to a rate that the SMSC can process Selecting a to-be-sent message in the buffered to-be-sent message; Step S406, the MMSC encodes the selected to-be-sent message, and the coded to-be-sent The sending message is sent to the SMSC. The method for limiting the delivery of the message to be sent is limited, and the problem that the SMSC exceeds the processing capability in a short time in the related art, and the message cannot be processed normally is avoided, thereby avoiding the moment when the multimedia message center service surges to the SMS center. Impact can not only reduce the performance requirements of the SMS center, but also improve the business success rate. Preferably, the MMSC can control the rate at which the message is sent by selecting a number of to-be-sent messages whose transmission threshold is in a scheduling period, where the SMSC can process the rate=transmission threshold/scheduling period. It is very convenient to process in this way, and the accuracy of the rate control can be adjusted by selecting different scheduling periods. The smaller the scheduling period is, the higher the accuracy of the rate control is, and the smoother the rate of message delivery is. Preferably, the MMSC controls the start of the scheduling period by a timer message, wherein the timer message is triggered at the beginning of each scheduling period.这样 In this way, when the timer message is received, a scheduling period can be restarted without determining whether to restart a scheduling period by means of scanning at any time, occupying a small system resource and being easy to manage. . Preferably, before the MMSC caches the to-be-sent message, the method further includes: determining whether the current delivery rate reaches a rate that the SMSC can process, and if yes, continuing the subsequent processing; otherwise, directly encoding the uncached to-be-sent message, encoding The subsequent to-be-sent message is sent to the SMSC. In the case that the current rate has not reached the rate that the SMSC can process, the method does not perform caching, directly encodes the message to be sent, reduces the link of the cache, and improves the processing performance of the system. Preferably, in the case that the cache of the message to be sent is cached, the message to be sent that is buffered is directly encoded, and the coded message to be sent is sent to the SMSC. This processing method prevents message loss due to cache failure and improves system stability. The solution provided above enables the message sent by the MMSC to the MMSC to be performed at a smooth rate, so as to avoid the instantaneous impact on the SMSC, which can reduce the performance requirements of the short message center, improve the service success rate, and protect the interests of the operator. The embodiment 1-2 described below takes the case of taking the second in the scheduling period as an example, and the above scheme is described as an example. For other scheduling periods, a similar method can be used for processing. Embodiment 1-2 combines the technical solutions of the above various preferred embodiments. Embodiment 1 FIG. 5 is a flowchart of a method for sending a message by an MMSC according to Embodiment 1, the method includes the following steps: Step 501: The MMSC service module generates a sending message, and sends a sending message to the MMSC cache processing module. Step 502: After receiving the message sent by the service module, the MMSC cache processing module requests the cache space and caches the message, or directly sends the message to the codec module. Step 503: The MMSC cache processing module controls the sending of a message at a certain rate per second. Go to the MMSC codec module; Step 504: The MMSC codec module receives the sent message, and then sends the message to the SMSC according to the SMPP protocol, and the message sent to the SMSC is submit_sm; Step 505: The SMSC receives the MMSC submit_sm message. Returning a response to the MMSC, submit sm resp, and sending a text message to the user;

The MMSC codec module receives the response message returned by the SMSC and decodes it into an MMSC internal message according to the SMPP protocol. It can be seen that by adding a cache processing module between the MMSC service module and the MMSC codec module, the sent message of the service module is directly sent to the cache processing module, and the cache processing module caches after receiving the sent message, and presses per second. A fixed number of messages are sent to the codec module, and the codec module is encoded and sent to the SMSC. In this way, the message sent by the MMSC to the SMSC is always in a smooth state in seconds, which can reduce the performance requirements of the short message center, improve the service success rate, and protect the interests of the operator. Embodiment 2 In this solution, the processing of the cache processing module is an important part. This embodiment describes the logic processing flow of the cache processing module in detail. FIG. 6 is the overall processing flow of the cache processing module according to the second embodiment. The figure includes the following steps: Step S601: The MMSC cache processing module starts to start; Step S602: The MMSC cache processing module applies for a cache space, initializes the idle queue, and has Using the queue, setting a second timer, etc.; Step S603: The MMSC cache processing module receives the processing message, and the processing message includes a service delivery message and a second timer message, where the service delivery message is sent by the service module. The second timer message is sent by the MMSC module itself for resetting every second. Step S604: The MMSC cache processing module determines whether the received message is sent by the service. If yes, step S605 is performed. If not, step S606 is performed. Step S605: The received message is sent to the service delivery message processing flow when the message is sent by the service; Step S606: If the message received by the cache processing module is not the service delivery message, it is determined whether it is a second timer message, and if yes, execution Step S607, otherwise returning; Step 4: S607: If the received message is a second timer message, the process proceeds to the timing message processing flow. Figure 7 is a process flow of the service delivery message in the second embodiment. As shown in Figure 7, the service delivery process of the step S605 may include the following steps: Step S701: Receive a service delivery message, first determine the second Whether the number of the packets that have been sent is less than the maximum number of allowed transmissions set by the system; if the result of the determination is true, it means that the transmission can be continued, then step S702 is performed; if the result of the determination is false, the quota is allowed to be sent within the second time. If the packet has been used, the packet cannot be sent, and the buffering is performed, step S704 is performed; Step S702: The service delivery message is sent to the codec module for encoding; Step S703: the number of the number of times sent in the second is increased by 1, and the step is returned; S704: determining whether the cached idle queue still has a free node, if there is a free node, indicating that the cache can be cached, step S705 is performed; if there is no free node, indicating that the cache is full, and the message is no longer cached, step S706 is performed; Step S705: Taking the idle node of the idle queue, the cache service sends a message, inserts it into the used queue, and returns; Step S7 06: This step is the exception handling mechanism of the cache queue. The service delivery message is sent to the codec module for encoding and return. FIG. 8 is a flowchart of a timing message processing procedure according to Embodiment 2, as shown in FIG. The S607 timing message processing procedure may include the following steps: Step S801: Receive a second timing message, indicating that a new one second is started, first clearing the number of sent lines in the second second; Step S802: determining the number of times that have been sent in the second second Whether it is less than the maximum number of allowed transmissions by the system (for the case that the scheduling period is seconds, the maximum number of the same number is the same as the maximum allowed rate); if the determination result is true, it indicates that the transmission can be continued, and then step S803 is performed; If the result of the judgment is H, it means that the quota allowed to be sent in the second time has been used up, and the transmission cannot be continued, and the process returns; Step S803: The used queue node is taken out, and the cached service delivery message is sent out and sent to the codec module for encoding, and The node is inserted into the idle queue; Step S804: The number of the already transmitted items in the second is incremented by 1, and the process proceeds to step S802. In summary, the solution provided by the embodiment of the present invention is compared with the original process, and the message buffer space is opened in the MMSC, and the message delivered by the service is temporarily cached, and then sent to the SMSC at a smooth rate to avoid the multimedia message center. When the business surges, it will cause an instant impact on the SMS center, which can reduce the performance requirements of the SMS center, improve the success rate of the service, and protect the interests of the operators.
