- the present invention relates to various types of short message systems in the field of communications, and in particular, to a method for scheduling data in a short message system. Background technique
- Short message systems or similar products have been set up in existing CDMA networks, GSM networks, and fixed telephone networks. While bringing convenient services to the majority of users and bringing huge profits to operators, the requirements of short message systems are becoming more and more stringent. Now, the security and robustness of short message systems have been aligned with the main equipment such as switches. . It is a basic requirement to ensure the normal operation of the short message system in any case.
- the basic architecture and data processing mode of the short message system determine that it has a lot of limitations in terms of resistance to traffic shocks and protection against database server failures, and the processing methods are relatively simple.
- the commonly used overload method for anti-traffic shock will reject or delay the sending of a large number of normal messages, resulting in a low sending rate and response rate of the short message system, and under the long-term large traffic shock, if the accumulated Sending a message to a certain level may cause overflow and message loss until the entire system is down due to excessive load.

- the processing strategy of the method when the load increases is mainly to temporarily delay the transmission. However, this will cause a low response rate of the system; the method also discards short messages that failed to be sent by modifying the temporary errors of the short messages to permanent errors.
- the higher the traffic pressure the more transmission failures will result. If the failure message is directly discarded without retransmission, the transmission success rate of the system will be greatly reduced.
- the database server is the core component of the short message system. Once a failure occurs, it will have a fatal effect on the entire short message system. Therefore, its security needs to be enhanced.
- system redundancy and disaster recovery technology is generally used to effectively control the failure rate of the entire system, but its implementation is relatively complicated and costly. Therefore, the current short message system urgently needs an efficient and easy method for intelligently scheduling data to enhance the robustness and security of the system, while ensuring the response rate and success rate of message sending.

Intelligent dispatch is performed to improve the ability of the short message system to resist the impact of traffic, and to ensure the sending rate and response rate of the short message system.
- the invention provides a method for intelligently scheduling data in a short message system, selecting an operating mode of the system according to a load index of the current short message system, and scheduling the short message service data according to the selected operating mode.
- the method for intelligently scheduling data in the short message system specifically includes the following steps:
- the operation mode of the short message system is divided into a normal mode and a stress-resistant mode when the traffic pressure is too high, and the switching mode and switching conditions of the configuration modes are configured, as well as the data scheduling strategy corresponding to each mode.
- the data generated by the business process is selectively discarded; the load indicator of the short message system is detected;
- the data is scheduled according to the data scheduling strategy corresponding to the current operating mode.
- the method for intelligently scheduling data further includes: dividing a short message service processing process into two independent processing processes of a short message initiation process and a short message termination process, and setting a termination suspension load threshold; among them,

- the basic idea of the present invention is to set multiple operating modes for the short message system, select the operating mode of the system according to the load index of the current short message system, and schedule the short message service data according to the selected operating mode.
- the operation mode of the short message system is first divided into a normal mode and a pressure-resistant mode, wherein the normal mode is a basic operation mode of the prior art, and the pressure-resistant mode is defined as the short message system under traffic pressure. Big time operation mode. Then configure the switching mode and switching conditions between each operation mode, and the data scheduling strategy corresponding to each operation mode. In the anti-stress mode, the data generated by the short message service processing process is selectively discarded. Detection system Compare the load index with the above switching conditions; if the load index meets the switching conditions, then complete the switching between the operating modes according to the above switching method. For the data generated during the short message service processing, follow the current operation of the short message system The data scheduling strategy corresponding to the mode schedules it.
- FIG. 1 is a functional module schematic diagram of a short message system adopting a method for intelligently scheduling data according to an embodiment of the present invention.
- the short message system mainly includes a service processor 101, an operation and maintenance center 102 connected to the service processor 101, and Active database 103.
- the service processor 101 is a core component for short message service processing, and various operation modes are implemented on the service processor 101.
- the operation and maintenance center 102 is a man-machine interface for providing a man-machine interface for configuring an operation mode.
- the main database 103 is a main data storage device for storing main data in the short message system, such as user information required for business processing, short message data generated by the business processing, and the like.
- Normal mode It is the operating mode when the short message system is normal.
- the business processor 101 is connected to the main database 103, and its business and data processing follow the existing standard processing flow; the system normally reads the user information required for business processing and saves the data generated by the business processing (such as Short message, etc.); In addition, the short message system completes the preservation of the data.
- Anti-stress mode It is the operation mode when the traffic pressure of the short message system is too high.
- the service processor 101 is connected to the main database 103, and the number generated by the short message service processing process is The data is selectively discarded.
- the short message system only saves part or all of the data.
- the data having no effect on the success rate of sending the short message is preferentially discarded.
- the operation mode configuration of the short message system is mainly completed through the operation and maintenance center 102.
- the related configuration items mainly include:
- Configuration switching mode The switching mode between various operating modes can be manual switching or adaptive switching or a combination of both. If it is a manual switchover, the manual switchover is performed according to the field environmental indicators of the short message system (including real-time performance statistics, traffic flow, system alarm types, etc.); if it is an adaptive switchover, the service processor 101 according to the system Load indicators (such as traffic pressure and database service availability) complete the switching of the operating mode by themselves according to the configured switching strategy. The switching of various operating modes takes effect immediately without resetting the system.
- the load index of the short message system adopts one or any combination of CPU usage rate, system read-write wait ratio, and cache usage rate; and the real-time acquisition of the system load index may use the commonly used detection CPU usage rate in the industry
- the system read and write wait ratio (10 wait) application program interface (API) functions obtained.

- the switching condition in the adaptive switching mode is: in the normal mode, if the load index exceeds the load mode load value for a set time, it automatically switches to the pressure mode; in the pressure mode If the load index is less than the load-resistance threshold of the compression mode for a set time, it will automatically switch to the normal mode.
- the short message system For example, if the short message system is running in the normal mode and the load indicator of the service processor 101 exceeds the normal level for 10 minutes due to traffic storms and other reasons, the system automatically switches from the normal mode to the stress-resistant mode; after the traffic storm has passed, After the short message system detects that the load index returns to normal level and lasts for 10 minutes, it switches from the anti-stress mode to the normal mode.
- the method described in this embodiment can make the short message system root According to the current traffic pressure and the available status of the database server, the appropriate operating mode and the corresponding data scheduling strategy are selected to process the data generated by the short message service, thereby achieving the purpose of enhancing the short message system's ability to resist traffic shocks.
- the short message service processing can be divided into two independent processing processes: the initiation processing of the short message and the end processing of the short message.
- the initiation process refers to the calling user sending a short message to the short message system;
- the final call process refers to the short message system delivering the short message to the destination user.
- Figure 2 shows a schematic diagram of the short message service processing process.

Insert into the short message buffer queue 220, and then send a response to the calling user that the call was successful. After the above operations are completed, the call processing 210 receives and processes the next call request. Call processing 210 No matter what the situation, unconditionally answer "11 ⁇ 2" call request and process it.
- Termination processing (thread) 230 According to the principle of first in, first out, the clear information of the short message is retrieved from the short message buffer queue 220, and the corresponding short message is searched from the main database 103 for termination, and the termination processing After completion, the changed information is saved into the main database 103 again. After each termination, the termination of the next message is continued.
- the service processing process of the short message is divided into a short message initiation process and a short message end call.
- the terminal call processing thread 230 can determine whether to compare the system load indicator detected by the short message system in real time with the configured terminal call suspension load threshold to determine whether End call processing is performed to decompress the system. If the current system load indicator exceeds the termination call suspension load threshold, the termination call processing is suspended; once the system load indicator is lower than the termination call suspension load threshold, the termination call processing is continued.
- the terminating thread can also perform terminating processing unconditionally. After performing the above operations, compare the system load index with the switching conditions, and then perform the subsequent steps.
- the following configuration items need to be configured through the operation and maintenance center 102: whether to terminate the call unconditionally; and the threshold of the termination call suspension load when the call is not unconditionally terminated.
- the termination call suspension load threshold is less than or equal to the compression mode load threshold.
- the operation mode of the short message system further includes a disaster tolerance mode.
- Disaster recovery mode is the operation mode when the main database of the short message system cannot provide services (such as system downtime, software upgrade, etc.).
- the switching conditions for switching between the disaster tolerance mode and the above two operating modes are: Whether the primary database of the short message system fails: If the primary database fails in normal mode or stress mode, switch to disaster tolerance Mode; if the primary database returns to normal in the disaster recovery mode, switch back to the operating mode of the short message system before the primary database fails.

- the measured current load index is compared with the load index thresholds of each load level to determine the current load level of the short message system. In this embodiment, after comparison, it can be determined that the current load level is a high level .
- the data scheduling strategy corresponding to the load level is selected in step 530, and the data scheduling strategy corresponding to each load level is: at a higher level At other times, only the successfully sent short messages are discarded (that is, not saved); at a high level, expired short messages, permanently failed short messages (more than 3 retransmission failures), and short message receipts are discarded; at a super high level When it is finished, all the processed short messages are further discarded, such as short messages waiting for retransmission. Therefore, in this embodiment, the data scheduling policy should adopt "discard successfully sent short messages, expired short messages, permanently failed short messages, and short message receipts".

- this embodiment further divides different load levels in the compression mode, and uses different data scheduling strategies to decompress the short message system for different load levels.
- the strategy is to follow As the system load level gradually increases, successful short messages, expired short messages, permanent failed short messages, and short message receipts are discarded until all processed short messages are completed.
- the temporary response of the short message is not temporarily delayed to ensure the response rate of message transmission, and when the discarded data type is selected, the success rate of message transmission is preferentially guaranteed at any time.
