The embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and system for sending a multimedia message, and a multimedia message center. Background technique

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

At present, MMSC (Multimedia Messaging Service Center, also known as MMS) delivers MM (Multimedia Messaging, also called MMS) to the receiving user terminal through PUSH (Push) message, namely: MMSC After receiving the MM, the PUSH notification message will be sent to the receiver user terminal first; if the receiver user terminal is in the normal state, the notification message will be received, and then automatically connected to the MMSC to extract the MM.

In the prior art, the MMSC generally passes through the WAP (Wireless Application).

Protocol, the wireless application protocol) The gateway connects to the SMSC (Short Message Center, short message center, also known as the short message center) or directly connects to the SMSC, and notifies the receiving MMS terminal user PUSH of the short message. The following is an example of the MMSC connecting to the SMSC through the WAP gateway. Figure 1 depicts the flow of MMSC sending MM. In the following flow, where C 1 represents MMSC To the interface between the WAP gateways, 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 is not directly connected to the mobile user terminal in actual application, the MM1 actually refers to The interface between the MMSC and the WAP gateway), for the convenience of description, the translation of Cl, C2, MM1 is omitted in the flow description.

Step 101: The MMSC sends a CI-contact.REQ (Notification Request) message to the WAP gateway. The Cl_notification.REQ (notification request) message indicates that MM has arrived at MMSC

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

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 other hand, MM1_contact.REQ (notification request) The message is sent to the user terminal.

Step 105: The user terminal returns a MM1_contact.RES message to the SMSC.

Step 106: The user terminal sends an MM1_enrollment.REQ (Extract MM Request) message to the WAP gateway.

Step 107: The WAP gateway forwards the CI_retrieve.REQ (Extract MM Request) message to the MMSC.

Step 108: The MMSC sends a CI-retrieve.RES message to the WAP gateway to send the MM to the WAP gateway.

Step 109: The WAP gateway sends an MMl_retrieve.RES (extract MM response) message to the user terminal, so as to forward the MM to the user terminal.

In carrying out the process of the present invention, the inventors have found that the prior art has at least the following problems:

In the MM process, the MMS relies on external network elements such as the WAP gateway and the SMSC, and the signaling interaction is too much. As a result, the reliability of the delivered MMS is reduced and the network delay is increased. Summary of the invention

Embodiments of the present invention will now be described in conjunction with the drawings, in which FIG.

An embodiment of the present invention provides a method for sending an MM. As shown in FIG. 2, the method includes the following steps: Step S301: A multimedia message center sends a query route request message to a home location register. It should be noted that, before the MMS sends a query route request message to the home location register, the method further includes the following steps: The sending direction sends a multimedia message to the multimedia message center, where the sender includes: a user terminal, a service provider server, or a mail server.

Step S302: The MMS receives the query routing response message returned by the home location register, where the query route response message includes routing information from the multimedia message center to the user terminal.

Step S303: The multimedia message center processes the multimedia message according to the routing information.

Specifically, the multimedia message center sends a multimedia message notification short message to the user terminal according to the routing information; the user terminal returns a short message response message to the multimedia message center, and when the multimedia message center receives the extracted multimedia message request message sent by the user terminal, according to the Extracting a multimedia message requesting to send the multimedia message to the user terminal; and when the multimedia message center does not receive the extracted multimedia message request message sent by the user terminal within a predetermined time, resending the MMS notification short message to the user terminal, And waiting to receive the extracted multimedia message request message sent by the user terminal.

In addition, in the method for sending the MM provided by the embodiment of the present invention, the query routing response message returned by the home location register further includes information about whether the user terminal activates the GPRS service; when the multimedia message center determines according to the query routing response message When the GPRS service is enabled, the user terminal sends a MMS notification short message to the user terminal according to the routing information, and receives a short message response message returned by the user terminal, and sends the short message response message to the user terminal according to the short message response message. Send the multimedia message. As shown in FIG. 3, this embodiment further provides a method for sending an MM. In this embodiment, a PUSH module is added to the MMSC, that is, the MMSC in the embodiment of the present invention includes a multimedia message center server and a PUSH module. The multimedia message center server is used to implement the function of the multimedia message center in the prior art, and the PUSH module is used to deliver the MM. A method for sending an MM message according to an embodiment of the present invention is described below with reference to FIG. In the embodiment of the present invention, the MAP Phase 2 + protocol is taken as an example, that is, the PUSH module uses the MAP Phase 2 + protocol to interact with other modules or devices, where MMx represents an interface between the MMSC and other surrounding network elements, and MM2 represents the internal of the MMSC. Interface, SRI indicates the query routing request, and MM1 indicates the interface between the MMSC and the WAP gateway. For the convenience of description, the translation of MMx, MM2, SRI, and MM1 is omitted in the flow description. It should be noted that the PUSH module can also interact with other modules or devices by using other standard protocols or using a customized protocol, and details are not described herein again.

Step 201: The sending direction sends, by the MMSC, an MMx_submit.REQ (submit request) message, and the message is submitted to the MMSC server in the MMSC. The submit request message includes a multimedia message, and the sender includes a user terminal, an SP (Service Provider) server, an Email Server (mail server), and the like.

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

Step 203: The MMSC server sends an MM2_notification-REQ (Notification Request) message to the PUSH module through the MM2 interface. In the message, the MMSC server may further set a field in the notification message (such as the set field SRR=1). Indicates that the PUSH module is required to return the delivery report delivered by the message, and can set a shorter message validity period (such as 2 hours), so that the PUSH module returns a delivery report to the MMSC server during the validity period.

Step 204: The PUSH module returns MM2_ notification_RES to the MMSC server.

(Notification response) Message.

Step 205: The PUSH module sends an SRI_For_SM (Query Routing Request) message to the HLR (Home Location Register) to obtain routing information of the user terminal, and further may perform one of the SRI_For_SM messages. Field (such as a field The gprsSupportlndicator is set to an active state to request the HLR to feed back the GPRS subscription information of the user terminal, and determine whether the user terminal activates the GPRS service according to the GPRS subscription information.

Step 206: The HLR returns an SRI_For_SM_RSS (Query Routing Response) message to the PUSH module, where the SRI_For_SM_RSP message includes routing information of the user terminal. Further, if the PUSH module requests the HLR to feed back the GPRS subscription information of the user terminal in step 205, the HLR may return the current location of the user terminal by using a field of the SRI_For_SM_RSP message (eg, the field sgsn-Number). GPRS subscription information (ie SGSNIP information).

Step 207: The PUSH module performs short message communication with the user terminal. That is, the PUSH module sends a MMS notification short message to the user terminal according to the routing information to notify the user terminal that the MM is available. After receiving the short message, the user terminal returns a short message response message to the PUSH module.

When the PUSH module sends a MMS notification short message, the MMS notification short message may be re-attempted according to the preset MMS notification short message policy, so as to increase the success rate of sending the MMS notification short message, and notify the user terminal to receive the message in time. MMS. The sending the MMS notification short message policy may be specifically as follows: 1. Sending a MMS notification short message to the user terminal at a specific time (for example, 1 hour) until the MMS notification short message succeeds or reaches a certain number of times (for example, 3 times) 2) 2. It is also possible to send a MMS notification short message only to the user terminal.

The PUSH module may use the result of the single-message MMS notification short message (short message response message) as the final result, and may also report the result of 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 the final result, that is, one of the results returned when the MMS notification short message is sent multiple times, one of which is successful, that is, the MMS notification short message is successful, otherwise, the MMS notification is sent. The short message failed.

Optionally, before the short message communication between the PUSH module and the user terminal, the PUSH module may further determine, according to the GPRS subscription information returned by the HLR, whether the user terminal activates the GPRS service.

Step 208: The PUSH module responds to the content of the short message response message (delivery result status) And the GPRS subscription information of the user terminal is returned to the MMSC server in the form of a delivery report, where the delivery report includes: sending a short message success report, a permanent failure report (eg, the user is an illegal user, the user does not open the GPRS service, etc.) Or a temporary failure "^ (such as user shutdown, etc.).

Step 209: If the delivery report is a permanent failure report, if the user does not open the GPRS service, the MMSC server determines, according to the delivery report, that the user terminal does not open the GPRS service (ie, does not support GPRS), then transfers the current MM to the Dreamnet album, and End the current message flow.

Step 210: If the delivery report is a successful delivery of the short message, the MMSC server will then receive the extracted MM request message sent by the user terminal.

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

Step 212: The MMSC server returns a delivery report of the delivered MM to the sender. Referring to steps 209-211, when the delivery report includes the following conditions, the MMSC server processes the MM according to the delivery obituary as follows:

1. Delivery report is a permanent failure report

On the basis of the completion of the delivery process, the MMSC can complete the following additional actions on the basis of the completion of the delivery process to facilitate the subsequent delivery of the message. Analysis:

If the reason for the failure of the MMS notification SMS delivery is "not opened GPRS service", the MMS will be directly transferred to the DreamWorks album;

When the sender is a user terminal, the sender can be alerted by an enhanced short message: the recipient number error message;

When the sender is an SP server, the MMSC can record the SP service code and the receiver user number for the BOSS (Telecom Operation Support System) to check the user information and the order relationship; the failure is recorded in the MM statistics bill and the log. In order to carry out more detailed and accurate statistics and analysis later; at the same time, when calculating the message success rate, the CDRs counted in this part of the message can be selectively eliminated.

2. The delivery report is a temporary failure report For the temporary failure report such as "user shutdown" and "user phone memory full", the MMSC server can re-notify the PUSH module to enable the PUSH module to re-communicate with the user terminal, so as to trigger the delivery of the MM, that is, according to the next The MMS notification short message policy resends the SMS to the user terminal. In this way, after the state of the user terminal changes, an SMS message can be received in time to trigger the receiving process of the MM. At the same time, the final delivery status of the SMS message can be reflected in the statistics CDR and the service log. In order to carry out more detailed and accurate statistics and analysis.

3. The delivery report is a successful report of the delivery of the short message.

If the MMSC server does not receive the extracted MM 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 cases such as "user terminal does not support MM function", "user receives misoperation deletion", "user terminal setting delay acquisition", "user does not want to obtain", etc., the retransmission period and retransmission times are required. Control, for example, set the retransmission period to 3 hours and the number of retransmissions to 3 times to avoid excessive retransmissions causing user dissatisfaction; in addition, for such cases, consider handling through the customer care call. In addition, the number of retransmissions of the MMS notification short message and the final delivery status in the statistics list and the service log can be further used to analyze the impact of the MMS notification short message retransmission on the message success rate.

Since the MMSC can know the final result of the MMS notification short message (permanent failure, temporary failure or successful delivery of the short message), the state of the user terminal can be obtained, and the above scheduling process can be performed for the state of the user terminal, and finally improved. The efficiency of MM sending.

In this embodiment, the MMSC is integrated into the MMSC to describe the MMS delivery process, and the various functions of the PUSH module can be directly set in the MMSC. Thus, in the method of this embodiment, the MMSC can be omitted. The communication between the server and the PUSH module makes the process of delivering the MMS simpler and more efficient.
