Description

A method and system for sending MMS, and MMS center

technical field

The invention relates to a communication technology, in particular to a method and system for sending a multimedia message, and a multimedia message center. the

Background technique

Although SMS (Short Message Service, short message service, also known as short message service) only transmits simple text information, SMS has become one of the most successful wireless data services. With the passage of time and the advancement of technology, people are no longer satisfied with simple text information, but are eager to pursue a rich and colorful multimedia experience; MMS (Multimedia Messaging Service, also known as MMS) The evolution of wireless data services has developed rapidly. the

At present, MMSC (Multimedia Messaging Service Center, also known as MMS center) sends MM (Multimedia Messaging, multimedia message, also known as MMS) to the receiving user terminal through PUSH (push) message, namely: MMSC After receiving the MM, it will first send a Push notification message to the receiving user terminal; if the receiving user terminal is in a normal state, it will receive the notification message, and then automatically connect to the MMSC to extract the MM. the

In the prior art, the MMSC generally connects to the SMSC through a WAP (Wireless Application Protocol, wireless application protocol) gateway or directly connects to the SMSC, and notifies the recipient user terminal user of a short message via PUSH. The following takes the MMSC connecting to the SMSC through a WAP gateway as an example, referring to the figure 1 Describe the process of MMSC sending MM. Wherein, in the following process, wherein, C1 represents the interface between the MMSC and the WAP gateway, C2 represents the interface between the WAP gateway and the SMSC, and MM1 represents the interface between the MMSC and the mobile user terminal (because the MMSC does not communicate with the mobile user terminal in practical applications) The mobile user terminal is directly connected, so MM1 actually refers to the interface between the MMSC and the WAP gateway), for the convenience of description, in the process description, the translation of C1, C2, and MM1 is omitted. the

Step 101, the MMSC sends a C1_notification.REQ (notification request) message to the WAP gateway. The C1_notification.REQ (Notification Request) message indicates that an MM has arrived at the MMSC. the

Step 102: After receiving the C1_notification.REQ (notification request) message, the WAP gateway sends the C2_notification.REQ (notification request) message to the SMSC. the

Steps 103-104, after receiving the C2_notification.REQ (notification request) message, the SMSC returns a C2_notification.RES (notification response) message to the WAP gateway on the one hand; on the other hand, sends the MM1_notification.REQ (notification request) message to the user terminal. the

Step 105, the user terminal returns an MM1_notification.RES (notification response) message to the SMSC. the

Step 106, the user terminal sends an MM1_retrieve.REQ (retrieve MM request) message to the WAP gateway. the

Step 107, the WAP gateway forwards the C1_retrieve.REQ (retrieve MM request) message to the MMSC. the

Step 108, the MMSC sends a C1_retrieve.RES (retrieve MM response) message to the WAP gateway, so as to send the MM to the WAP gateway. the

Step 109, the WAP gateway sends the MM1_retrieve.RES (retrieve MM response) message to the user terminal, so as to forward the MM to the user terminal. the

In the process of realizing the present invention, the inventor found that in the above process, since the MMSC cannot know the final result returned by the Push notification request message (such as whether the sending is successful), the status of the user terminal cannot be obtained, and thus cannot make a decision. Targeted scheduling processing to improve the efficiency of message sending. Secondly, when some user terminals are not capable of receiving MM (for example, the GPRS service is not activated), they can receive short messages. Therefore, when the PUSH notification message is sent successfully, the user terminal cannot successfully obtain the MM message, so that the MMSC is in a long-term Time waiting process wastes resources of MMSC. Third, in the process of delivering MM by MMSC, due to the dependence on external network elements such as WAP gateway and SMSC, there are too many signaling interactions, which reduces the reliability of sending MMS and increases the network delay. the

Detailed ways

In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings. the

Embodiment one

As shown in Figure 2, the present embodiment provides a method for issuing MM. In this embodiment, a PUSH module is added in the MMSC, that is, the MMSC in the embodiment of the present invention includes a multimedia message center server and a PUSH module, wherein The multimedia message center server is used to realize the function of the multimedia message center in the prior art, and the PUSH module is used to deliver the MM. The following describes the method for sending MM messages according to the embodiment of the present invention with reference to FIG. 2 . In the embodiment of the present invention, take the MAP Phase2+ protocol as an example, that is, the PUSH module uses the MAP Phase2+ protocol to interact with other modules or devices, where MMx represents the interface between the MMSC and other peripheral network elements, and MM2 represents the internal interface of the MMSC, SRI means query routing request, and MM1 means the interface between MMSC and WAP gateway. For the convenience of description, in the process description, the translation of MMx, MM2, SRI, and MM1 is omitted. It should be noted that the PUSH module can also use other standard protocols or use custom protocols to interact with other modules or devices, which will not be described here. the

Step 201, the sender sends an MMx_submit.REQ (submission request) message to the MMSC, and the message is submitted to the MMSC server in the MMSC. Wherein, the submission request message includes a multimedia message, and the sender includes a user terminal, an SP (Service Provider, service provider) server, an EmailServer (mail server) and the like. the

Step 202, the MMSC server returns an MMx_submit.REQ (submit response) message to the sender. the

Step 203, the MMSC server sends the MM2_notification_REQ (notification request) message to the PUSH module through the MM2 interface, in which the MMSC server can further indicate that the PUSH is required by setting a certain field in the notification message (such as setting the field SRR=1). The module returns the delivery report issued by the message, and can set a shorter message validity period (such as 2 hours), so that the PUSH module returns the delivery report to the MMSC server within the validity period. the

Step 204, the PUSH module returns an MM2_notification_RES (notification response) message to the MMSC server. the

Step 205, PUSH module sends SRI_For_SM (query routing request) message to HLR (Home Location Register, home location register), to obtain the routing information of user terminal, and can further be set to a certain field (such as field gprsSupportIndicator) of SRI_For_SM message Valid state, to request the HLR to feed back the GPRS subscription information of the user terminal, and determine whether the user terminal has opened the GPRS service according to the GPRS subscription information. the

Step 206, the HLR returns an SRI_For_SM_RSP (query route response) message to the PUSH module, and the SRI_For_SM_RSP message includes the route information of the user terminal. Further, if in step 206, the PUSH module requests the HLR to feed back the GPRS subscription information of the user terminal, then the HLR can return the current GPRS subscription information (i.e. SGSNIP information). the

Step 207, the PUSH module communicates with the user terminal by short message. That is, the PUSH module sends an MMS notification short message to the user terminal according to the routing information to inform the user terminal that MM is available, and the user terminal returns a short message response message to the PUSH module after receiving the short message. the

When the PUSH module fails to send the MMS notification short message, it can retry sending the MMS notification short message according to the preset MMS notification short message strategy, so as to increase the success rate of sending the MMS notification short message and notify the user terminal to receive it in time MMS. The policy of sending the multimedia message notification short message can be specifically: 1. Send the multimedia message notification short message to the user terminal every specific time (such as 1 hour), until the success of sending the multimedia message notification short message or reaching a specific number of times (such as 3 times) ); 2. It is also possible to send the MMS notification short message only once to the user terminal. the

The PUSH module can send the result (short message response message) of the MMS notification short message once as the final result, or the result of sending the MMS notification short message multiple times as the final result. In this embodiment, multiple times The result of sending the MMS notification short message is taken as the final result, that is, among the results returned when sending the MMS notification short message multiple times, one of them is successful, that is, the sending of the MMS notification short message is considered successful, otherwise, the MMS notification message is sent Failed to notify short message. the

Optionally, before the PUSH module and the user terminal carry out short message communication, the PUSH module can also judge whether the user terminal has opened the GPRS service according to the GPRS subscription information returned by the HLR, if yes, then perform step 207, otherwise, directly go to step 208 . the

Step 208, the PUSH module returns the content (delivery result status) and the GPRS subscription information of the user terminal to the MMSC server in the form of a delivery report in the short message response message, and the delivery report includes: sending a short message success report, permanent Failure report (such as the user is an illegal user, the user has not opened the GPRS service, etc.) or temporary failure report (such as the user shuts down, etc.). the

Step 209, if the MMSC server judges according to the delivery report that the user terminal has not activated the GPRS service (that is, does not support GPRS), transfer the current MM to the Monternet album, and end the current message process. the

Step 210, if the delivery report includes that the delivery of the short message is successful, the MMSC server will then receive the MM extraction request message sent by the user terminal. the

Step 211: After receiving the MM extraction request message sent by the user terminal, the MMSC server returns an MM extraction response message to the user terminal, so as to send the MM to the user terminal. the

Step 212, the MMSC server returns the delivery report of the MM to the sender. the

Referring to steps 209-211, when the delivery report includes the following situations, the MMSC server processes the MM according to the delivery report as follows:

1. When the delivery report is a permanent failure report

For permanent failure reports such as "illegal user" and "not activated GPRS service", the MMSC can complete the following additional actions after completing the delivery process, so as to facilitate subsequent analysis of the message delivery process:

If the reason for the failure to send the MMS notification message is "the GPRS service has not been activated", the MMS will be transferred directly to the Monternet album;

When the sender is a user terminal, the sender can be reminded by an enhanced SMS message: the receiver's number is wrong;

When the sender is an SP server, the MMSC can record the SP service code and the receiver's user number for BOSS (telecom operation support system) to check the user information and order relationship;

Record such failures in the statistical bills and logs sent to MM for more detailed and accurate statistics and analysis in the future; at the same time, when calculating the success rate of messages, you can selectively exclude the bills of these messages. the

2. The delivery report is a temporary failure report

For temporary failure reports such as "the user shuts down the phone" and "the memory of the user's mobile phone is full", the MMSC server can notify the PUSH module again, so that the PUSH module can communicate with the user terminal again, so as to trigger the delivery of MM, that is, according to the following The MMS notification short message policy resends SMS to the user terminal. In this way, when the state of the user terminal changes, the SMS message can be received in time to trigger the receiving process of the MM. At the same time, the final sending status of the SMS message can be reflected in the statistical bill and service log. For more detailed and accurate statistics and analysis in the future. the

3. The delivery report is a report on the successful sending of short messages

If the MMSC server does not receive the MM extraction request message sent by the user terminal for a period of time, the MMSC server may instruct the PUSH module to resend the MMS notification short message within a certain period. Considering that there are many situations such as "the user terminal does not support the MM function", "the user receives a mistaken operation and deletes", "the user terminal sets a delay to obtain", "the user does not want to obtain", so it is necessary to adjust the retransmission cycle and retransmission times Control, for example, set the retransmission cycle to 3 hours and the number of retransmissions to 3 times, so as not to cause user dissatisfaction due to excessive retransmissions; in addition, you can also consider handling such cases through the customer service call. In addition, the number of retransmissions of the MMS notification short message and the final delivery status are reflected in the statistical call list and business log, which can be further used to analyze the impact of the retransmission of the MMS notification short message on the success rate of the message. the

In this embodiment, a PUSH module is integrated in the MMSC to describe the MMS sending process, and various functions of the PUSH module can also be directly set in the MMSC, so that in the method of this embodiment, the MMSC can be omitted The communication between the server and the PUSH module makes the process of sending MMS simpler and more efficient. the
