Description

 Method and device for processing expired short message

 The present invention relates to the field of communications, and in particular, to a method and apparatus for processing expired short messages. Background technique

 Short message service is one of the most important value-added services of mobile telecom operators, and it is also the most widely used and most frequently used service. In order to continuously improve the operational capabilities of the business, the short message center is constantly improving.

 The short message service is characterized by non-real time and timeliness. The short message service is different from the voice service. The voice service is real-time, and it is disconnected when it is not connected. The short message service is non-real-time. The source user sends a short message to the destination user. The destination user does not receive the message in real time but has a delay. If the destination user is in the state of shutdown or out of service, the short message center will cache the message and retry. When the destination user status is available again, the message can still be received.

 However, the short message center cannot cache unrestricted short messages that cannot be delivered temporarily. Therefore, you need to set the time limit for each short message, that is, the expiration date. The short message validity period refers to the effective period of a short message. The source user can set the validity period for the short message. If the message cannot be successfully transmitted to the destination user within the validity period, the message will expire and cannot be delivered. Short message expiration often occurs, for example, the destination user is shut down, or the destination user is out of service, and so on. Depending on the user's usage and short message service characteristics, the default validity period of short messages is not too long, typically 2 to 3 days.

However, in view of the above characteristics of the short message service, the prior art has the following drawbacks: When the destination user can receive the message, for example, the destination user returns from abroad (ie, has been transferred back to the service area), or the mobile phone is damaged and repaired, etc. In other cases, since the previous short message has expired, the destination user can no longer receive these short messages, which may bring a certain degree of loss to the target user and reduce the user experience. Summary of the invention

 In the embodiment of the present invention, a processing method and apparatus for processing a short-lived short message are proposed, so that the user terminal can selectively receive a short message that has passed the validity period without significantly increasing the service burden of the short message center.

 In this embodiment, in the embodiment, a valid period message pool (referred to as an expired message pool) is added to the short message center, and the short message that the source user terminal fails to send to the destination user terminal and has expired is stored in the expired message pool. The short message center does not retry the short message in the expired message pool, and only sends the short message in the expired message pool again at the request of the user terminal.

 The destination user terminal may send an instruction (eg, a short message, a voice instruction, etc.) of the specified format content to the short message center, and after receiving the instructions, the short message center obtains the short message that meets the conditions specified by the instruction from the expired message pool. And sent to the destination user terminal.

 Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , in the embodiment of the present invention, the communication system includes at least a short message center, and the short message exceeding the expiration date sent by the source user terminal to the destination user terminal is stored in the expired message pool; the so-called expired message The pool is a dedicated storage area of the expired short message. Then, when receiving the instruction for obtaining the expired short message sent by the destination user terminal, the short message center obtains the corresponding expired short message in the expired message pool, and expires Send a short message to the item User terminal.

 Referring to FIG. 2, in the embodiment of the present invention, the short message center includes a first processing unit 20, a communication unit 21, and a second processing unit 22, where

 The first processing unit 20 is configured to store, by the source user terminal, the short message that exceeds the validity period of the destination user terminal into the expired message pool;

 The communication unit 21 is configured to receive an instruction sent by the destination user terminal to obtain an expired short message.

 The second processing unit 22 is configured to: obtain, according to the instruction sent by the destination user terminal, an expired short message corresponding to the instruction in the expired message pool, and send the expired short message to the destination user terminal by using the communication unit 20 .

 The communication unit is further configured to receive a short message sent by the source user terminal to the destination user terminal, send the short message to the destination user terminal, and determine that the destination user terminal fails to receive the short message; the first processing unit, And is further configured to save the short message that the communication unit determines that the destination user terminal receives the failure to the waiting message queue, and set an expiration date of the short message.

 The communication unit is further configured to resend the short message to the destination user terminal according to a set period within an expiration period set by the first processing unit, and notify the first process when the sending is successful. The unit deletes the short message from the waiting message queue.

 The first processing unit is further configured to: when the communication unit determines that the destination user terminal resumes normal communication according to the network side notification, send the short message stored in the waiting message queue to the destination user terminal.

 The instruction for acquiring the expired short message sent by the destination user terminal received by the communication unit includes: a source address for uniquely identifying the destination user terminal; or, a source address for uniquely identifying the destination user terminal, and expiration One or any combination of the start submission time of the short message, the end submission time of the expired short message, and the keywords in the expired short message.

The second processing unit is further configured to acquire, in the expired message pool, a compliance An expired short message of the query condition represented by the parameter contained in the instruction.

 The second processing unit is further configured to detect an occupancy rate of the expired message pool during a specified period, and save the time in the expired message pool when determining that the occupancy rate reaches a set threshold The longest part of the expired short message is deleted.

 In this embodiment, the expired message pool may be set in the short message center, as a built-in module of the short message center, or may be an independent device, such as a database server, and is not described herein.

 Based on the foregoing technical solution, as shown in FIG. 3, in the embodiment of the present invention, the user terminal A is the source user terminal, and the user terminal B is the destination user terminal. The detailed process of processing the expired short message in the short message center is as follows:

 Step 300: The short message center user terminal B fails to receive a short message sent by the user terminal A to it, which is called short message a.

 In the actual application, the short message a sent by the user terminal A to the user terminal B is sent to the short message center, and when the short message center sends the short message a to the user terminal B, the user terminal B fails to receive normally, for example, the user terminal If the short message center receives the terminal call response returned by the wireless side (for example, the base station), the short message center determines that the user terminal B is absent, that is, the short message a sent by the user terminal A cannot be normally received, that is, the short message a Failed to send.

 Step 310: The short message center caches the short message a in the waiting message queue and sets a corresponding expiration date.

Preferably, the short message a has a validity period of 2 to 3 days. During the validity period, the short message center will retry the transmission according to the configured retry policy, that is, periodically to the user terminal B according to a preset period. Resend the short message a. If the short message a retry is successfully sent within the expiration date, the short message center marks the short message a successfully processed, does not store in the expired message pool, and is deleted from the waiting message queue; If the short message a fails to be sent, the short message center will store the short message a in the expired message pool when the validity period expires. Step 320: The short message center stores the short message a exceeding the expiration date in the expired message pool. After the short message a is moved into the expired message pool, the short message center will no longer retry sending the short message a.

 In this process, the short message center may continue to receive the short message sent by the user terminal a or other user terminal to the user terminal B, and store the short message that failed to be sent into the waiting message queue and set a limited time limit, and the expiration date will be exceeded. The short message stores the expired message pool, which will not be described here.

 Step 330: The short message center determines that the user terminal B resumes normal communication.

 When the user terminal B resumes normal communication, for example, the user terminal B is powered on, or the user terminal B re-enters the service area (for example, the user terminal B enters the domestic service area from the foreign service area, or the signal shielding area performs the signal unshielded area. Or,), or the user terminal B is changed from the other unavailable state to the available state. At this time, the user terminal B will perform network registration. Therefore, the network side (for example, the base station) knows that the user terminal B has resumed normal communication. Then, the network side will notify the short message center of this situation, so that the short message center knows that the user terminal B can perform normal communication at this time.

 In this embodiment, when the network side notifies the user terminal B to resume normal communication, the short message center may be directly notified by the base station, or may be notified by the base station to the home location register (HLR, Home Location Register), and then notified by the HLR. Message Center.

 Step 340: The short message center determines that the user terminal B returns the normal communication, and sends the short message for the user terminal B buffered in the waiting queue message queue to the user terminal B.

The short messages in the waiting message queue that can be cached are all short messages that have failed to be sent and have not exceeded the expiration date. Therefore, the short message center should immediately send these short messages to the user terminal B when it knows that the user terminal B resumes normal communication. For short messages in the expired message pool, although it is also a short message that fails to be sent, the short message center will not actively send the message, but the user terminal B should actively obtain the short message center, so that it can be reduced. The system is running negative Load, effectively save system overhead.

 Step 350: The short message center receives an instruction sent by the user terminal B to obtain the expired short message a. In this embodiment, the instruction may also be sent in the form of a short message.

 In this embodiment, the user can edit the above instruction in the specified format on the user terminal B to obtain the expired short message a. For example, the editing format of the above instruction is as follows:

 Orig Addr: Source address of the expired short message, required parameters,

 Orig Addr can be used to uniquely identify user terminal B;

 Begin—Sets: The initial submission time of the expired short message, optional parameters;

 End Scst: End submission time of expired short message, optional parameters;

 Key Word: The keyword in the expired short message content, optional parameters.

 The other three parameters may be one or any combination of the other parameters. The content included in the parameter Orig Addr is the identifier of the user terminal B. For example, when the user terminal B is a mobile phone, Orig—Addr is its mobile number. The default destination address of this command is the short message center address.

 After receiving the above instructions, the short message center will find out in the expired message pool whether there is an expired short message that meets the query condition represented by the parameter according to the parameters it contains.

 Step 360: After receiving the instruction of the expired short message a, the short message center obtains the corresponding expired short message a in the expired message pool, and sends the expired short message a to the user terminal B.

 In an actual application, there may be more than one expired short message for the user terminal B, so as long as it is an expired short message that meets the parameters set in the instruction sent by the user terminal B (ie, an expired short message that meets the query condition of each parameter representation) The description should be made from the expired message pool and sent to the user terminal B. In this embodiment, only one expired short message a is taken as an example, but the implementation is not limited thereto.

In this embodiment, the short message center receives the short time sent by the user terminal B to obtain an expired short. When the instruction of the message a is instructed, the format of the instruction is checked. If it is correct, the short message center will obtain the short message a in the expired message and send it to the user terminal B. If not, the short message center will send the correct instruction. The prompt message is sent to the user terminal B. The function of the prompt message is mainly to indicate the error of the instruction format to the user terminal B, and prompt the correct format, so that the user terminal B corrects the instruction.

 On the other hand, in order to avoid unnecessary overhead of the system, preferably, if the short message center fails to send the expired short message a extracted from the expired message pool, the retry transmission is not performed, and the retry is directly performed. Expired message pool.

 Based on the above embodiment, preferably, the short message center will detect the occupancy rate of the expired message pool according to a specified period (for example, every morning, or a low traffic period), when the occupancy rate reaches a set threshold. When the expired short message exceeding the specified period is deleted, for example, the partially expired short message with the longest saved time is deleted to ensure a certain idle rate in the expired message pool.

 In summary, in the embodiment of the present invention, after the short message expires, the short message center does not directly delete the short message center, but transfers to the expired message pool, and receives the instruction for acquiring the expired message sent by the destination user terminal. Then, it is found in the expired message pool whether there is an expired message that satisfies the query condition included in the above instruction, and the expired short message that meets the query condition is taken out from the expired message pool and sent to the destination user terminal. Obviously, in this embodiment, the expired short message is not directly deleted by the short message center, and is only sent to the short message center when the destination user terminal intentionally obtains, so that after the short message exceeds the expiration date, the short message can still be Provided to the user terminal according to the user's requirements, thereby improving the quality of service of the system, and because the expired short message is sent when requested by the user, the performance of the short message center is very low, and the short message center is not caused. The running load guarantees the service performance of the short message center.

Obviously, those skilled in the art should understand that the above modules or steps of the present invention can be implemented by a general-purpose computing device, which can be concentrated on a single computing device or distributed over a network composed of multiple computing devices. Alternatively, they can be executed by computing devices The program code of the lines is implemented so that they can be stored in the storage device by the computing device, or they can be made into individual integrated circuit modules, or a plurality of modules or steps can be made into a single integrated circuit module. to realise. Thus, the invention is not limited to any specific combination of hardware and software.

 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. within the spirit and scope of the invention are intended to be included within the scope of the invention. Industrial applicability

 In the present invention, the short message center stores the short message of the expiration date of the source user terminal to the destination user terminal in the expired message pool, and the short message center receives the short message sent by the destination user terminal for obtaining the expired short message. When the instruction is executed, the expired short message corresponding to the instruction is obtained in the expired message pool, and the expired short message is sent to the destination user terminal. In this way, after the short message exceeds the expiration date, the short message can be further provided to the destination user terminal according to the user's requirement, thereby improving the service quality of the communication system, improving the user experience, and issuing the expiration short when the user requests. The message, therefore, has a very low impact on the performance of the short message center, does not cause an operational load on the short message center, and guarantees the service performance of the short message center.
