The embodiments of the present invention will be further described with reference to the accompanying drawings. The specific embodiments described herein are merely intended to explain the present invention and are not intended to limit the invention. As shown in FIG. 1, FIG. 1 is a flowchart of a first embodiment of a short message call flow control method according to the present invention. The short message call flow control method mentioned in this embodiment includes the following steps: Step S10: Receive a short message sent by a mobile switching center or a service provider; when sending a short message, the user sends the short message to the mobile switching center, and is moved by the mobile terminal. The switching center submits to the short message center; the service short message sent by the service provider is submitted by the service provider to the short message center by using the SMPP protocol. Step S20: Query the number segment of the short message; an MSC area may be divided into multiple BSC number segments, and the short message is distributed to the base station corresponding to the segment number according to the number of the receiver for delivery and transmission. For example, divide the area into two MSC areas, each MSC area negative Responsible for two BSC segments, there are a total of 4 BSC segments. The short message center sets the maximum traffic threshold for each segment in advance. For example, set the number of segments 1 for 100 segments/second and the segment segment 2 for 200 segments/second. Set 300/sec for segment 3 and 400/sec for segment 4. Step S30, counting the actual number of delivery messages of the short message belonging segment period in the current time period; when a short message arrives, the short message center adds 1 to the actual delivery message number in the current time period. Step S40: determining whether the number of actual delivery messages of the short message belonging to the current time period is less than the traffic threshold of the number segment of the short message; in order to control the traffic of the base station controller corresponding to each number segment, if the short message arrives at the traffic Within the threshold range, the delivery operation is performed. If the short message that arrives exceeds the traffic threshold, it is not sent temporarily, effectively preventing the base station controller from being overloaded. Step S50: When the number of actual delivery messages of the short message belonging to the current time period is less than the traffic threshold of the number segment of the short message, the short message is delivered to the base station controller corresponding to the number segment of the short message. In this embodiment, by controlling the traffic of the base station controllers of each segment of each area, the control of the short message call traffic is refined to the number segment, so that the control is more accurate, the configuration is more flexible, and the system overload is effectively avoided.

As shown in FIG. 2, FIG. 2 is a flowchart of a second embodiment of a short message call flow control method according to the present invention. The embodiment is based on the embodiment shown in FIG. 1. After step S40, the method further includes: Step S61: When the number of actual delivery messages of the short message belonging to the current time period is greater than or equal to the traffic threshold of the number segment of the short message , the short message is cached; Step S62, the next time period arrives, and the process returns to step S30. In this embodiment, when the short message that arrives in the current time period exceeds the traffic threshold range, the short message is temporarily not sent, and when the next time period arrives, the actual number of delivery messages of the short message belonging segment in the next time period is re-stated. When the number of actual delivery messages of the short message belonging to the next time period is less than the traffic threshold of the number segment of the short message, the short message is sent out in the next time period, if the actual number of delivery messages in the next time period is still greater than If the traffic threshold is equal to or equal to the traffic threshold, the short message will continue to be sent. If the next time interval is reached, the statistics and judgments are repeated, and the loop is repeated until the traffic of the number segment of the short message meets the threshold range. Since the BSC traffic of each segment is finely controlled in this embodiment, the system load is effectively prevented from being overloaded by the base station. As shown in FIG. 3, FIG. 3 is a flowchart of a third embodiment of a short message call flow control method according to the present invention. The embodiment is based on the embodiment shown in FIG. 2, and the step S30 specifically includes: Step S31, counting the actual number of delivery messages of the high priority message and the actual delivery message of the ordinary message in the current period of the short message belonging segment segment; To ensure that important messages are delivered preferentially, the messages need to be classified, and the short messages are classified into high-priority messages and ordinary messages. Point-to-point short messages and important SP short messages are classified as high-priority messages. The class is a normal message. The total traffic of the message sent in the same segment of the high-priority message and the normal message per second cannot be greater than the threshold set by the segment. The number of messages to be delivered is the number of short messages that the MSC or SP requests to deliver to the short message center, and the number of actual delivery messages refers to the number of short messages actually delivered to the base station controller in the current time period. In order to balance the efficiency, the traffic sent by the two types of messages at the moment is dynamically adjusted according to the traffic of the high-priority message and the normal message. The traffic of the two types of messages at a certain moment can be obtained as the actual number of delivered messages in real time; or the traffic submitted to the short message center at the historical moment of the high priority message (ie, the number of messages to be submitted) is used to estimate the current high priority message. Traffic, and the estimated traffic is subtracted from the segment threshold as the maximum allowed traffic at the current time of the normal message.

As shown in FIG. 4, FIG. 4 is a flowchart of a fourth embodiment of a short message call flow control method according to the present invention. The embodiment is based on the embodiment shown in FIG. 3. Step S40 specifically includes: Step S41: determining the type of the short message that arrives; Step S42, when the short message that arrives is a high priority message, determining the actual content of the high priority message. Whether the number of delivery messages is smaller than the difference between the maximum traffic threshold of the number segment of the short message and the actual number of delivery messages of the normal message; the dynamic real-time calculation threshold is used for the high priority message, the maximum traffic threshold is recorded as Max, and the high priority message threshold is recorded as Imax, Im _ax = Ma _X — The actual number of ordinary messages for the current time period. If the current high-priority message actually delivers the number of messages <Imax, the high-priority message can continue to be delivered. In step S43, when the short message that arrives is a normal message, it is determined whether the actual number of delivery messages of the ordinary message is smaller than the normal message threshold of the number segment of the short message, and is smaller than the maximum traffic threshold of the number segment of the short message and the high priority message. The difference between the actual number of delivery messages. In order to ensure the smoothness of the message traffic, the sliding window mechanism is used to calculate the common message threshold, and the common message threshold of the current time period is estimated by the number of high priority messages to be delivered in the historical period. The following method is specifically adopted: Statistics before the current time period N The number of to-be-delivered messages of the high-priority message T1, Τ2 Τη, Ν is a natural number; the maximum traffic threshold Max of the number segment to which the short message belongs is obtained; the common message threshold Umax of the number segment of the short message in the current time period is determined. , the expression is: nma _X = Max - ri + T2 + ... + Tn) ÷ N. In this embodiment, Ν=3 is taken as an example to obtain the number of to-be-delivered messages T1, Τ2, Τ3 of the high-priority message in the first three time periods, that is, the MAC and the SP request to the short message center within three time periods before the current time period respectively. The number of high-priority messages submitted, the average traffic of high-priority messages in the three periods before the current time period is (Tl+T2+T3)÷3, then the common message threshold of the current time period IIm _ax =Ma _X — (Tl+ T2+T3)÷3. The following conditions must be met to determine whether the ordinary message can continue to be delivered: The number of ordinary delivery messages of the normal message <IIma _X , and the number of ordinary delivery messages of the normal-level message <Max—the number of actual delivery messages of the high-priority message. This embodiment adopts a sliding window mechanism to ensure the smoothness of message traffic, and also ensures that high-priority messages are sent preferentially, taking into account the balance between flow control and delivery efficiency.

As shown in FIG. 5, FIG. 5 is a flowchart of a fifth embodiment of a short message call flow control method according to the present invention. The embodiment is based on the embodiment shown in FIG. 2, and after step S50, further comprising: step S71, determining whether the short message fails to be delivered; if yes, executing step S72; if not, ending the process; step S72, determining the short Whether the delivery error code of the message is the home location register error code; if yes, step S73 is performed; if no, step S74 is performed; step S73, the number of actual delivery messages of the short message belonging number segment in the current time period is decremented by one, The short message is buffered, and the process returns to step S30; in step S74, the short message is buffered, and the process returns to step S30. Before the short message center delivers the short message to the base station, it will first query the route by the HLR (Home Location Register). If the HLR returns a failure when querying the route, such short message will not be delivered to the BSC. It will not cause load impact, and can be deducted from the actual actual delivery BSC number. Therefore, it can be judged according to the error code returned by the core network whether it is a route failure returned by the HLR.

As shown in FIG. 6, FIG. 6 is a schematic structural diagram of a first embodiment of a short message call flow control apparatus according to the present invention. The short message call flow control device mentioned in this embodiment includes: The receiving module 10 is configured to receive a short message sent by the mobile switching center or the service provider; the querying module 20 is configured to query the number segment of the short message; and the statistics module 30 is configured to calculate the actual number of the short message belonging to the current time period. The determining module 40 is configured to determine whether the actual number of delivery messages of the short message belonging to the current time period is less than the traffic threshold of the short message belonging to the number segment; the delivery module 50 is configured to determine, when the determining module 40 determines that the short message belongs to When the number of actual delivery messages in the current period is less than the traffic threshold of the number segment to which the short message belongs, the short message is delivered to the base station controller corresponding to the number segment to which the short message belongs. In this embodiment, when the short message is sent by the user, the mobile terminal sends the short message to the mobile switching center, and the mobile switching center delivers the short message message; the service provider sends a short message to the service provider, and the service provider submits the short message by using the SMPP protocol. Message Center. An MSC area may be divided into a plurality of BSC number segments, and the short message is distributed to the base station corresponding to the number segment according to the number of the receiver for delivery and transmission. For example, the area is divided into two MSC areas, each MSC area is responsible for two BSC segments, and there are a total of four BSC segments. The short message center sets the maximum traffic threshold for each segment in advance, for example, a checkpoint segment. 1 Set 100 bars/second, set segment 2 for 200 segments/second, check segment 3 for 300 bars/second, and check segment 4 for 400 bars/second. When a short message arrives, the short message center increments the actual number of delivery messages in the current time period by one. In order to control the traffic of the base station controller corresponding to each number segment, if the short message that arrives is within the traffic threshold range, the delivery operation is performed. If the short message that arrives exceeds the traffic threshold, the short message is not sent, and the base station controller is effectively avoided. The load is too large. In this embodiment, by controlling the traffic of the base station controllers of each segment of each area, the control of the short message call traffic is refined to the number segment, so that the control is more accurate, the configuration is more flexible, and the system overload is effectively avoided.

As shown in FIG. 7, FIG. 7 is a schematic structural diagram of a second embodiment of a short message call flow control apparatus according to the present invention. In this embodiment, on the basis of the embodiment shown in FIG. 6, the cache module 60 is added, and is configured to determine, when the determining module 40 determines that the number of actual delivery messages of the short message belonging to the current time period is greater than or equal to the number segment of the short message. When the traffic threshold is used, the short message is cached; the statistics module 30 is further configured to: when the next time period arrives, count the actual number of delivery messages of the short message belonging segment segment in the next time period; the determining module 40 is further configured to determine the short message belonging number segment Whether the actual number of delivery messages in the next time period is less than the traffic threshold of the number segment to which the short message belongs. In this embodiment, when the short message that arrives in the current time period exceeds the traffic threshold range, the short message is temporarily not sent, and when the next time period arrives, the actual number of delivery messages of the short message belonging segment in the next time period is re-stated. When the number of actual delivery messages of the short message belonging to the next time period is less than the traffic threshold of the number segment of the short message, the short message is sent out in the next time period, if the actual number of delivery messages in the next time period is still greater than If the traffic threshold is equal to or equal to the traffic threshold, the short message will continue to be sent. If the next time interval is reached, the statistics and judgments are repeated, and the loop is repeated until the traffic of the number segment of the short message meets the threshold range. Since the BSC traffic of each segment is finely controlled in this embodiment, the system load is effectively prevented from being overloaded by the base station.

In the embodiment of the present invention, the statistics module 30 is specifically configured to: count the number of actual delivery messages of the high priority message and the actual number of delivery messages of the ordinary message in the current time period of the number segment of the short message. In this embodiment, in order to ensure that important messages are preferentially delivered, the messages need to be classified, the short messages are classified into high-priority messages and ordinary messages, and the point-to-point short messages and important SP short messages are classified into high-priority messages. The other messages are classified as ordinary messages. The total traffic of messages sent in the same segment of the high-priority message and the ordinary message per second cannot be greater than the threshold set by the number segment. The number of messages to be delivered is the number of short messages that the MSC or SP requests to deliver to the short message center. The actual number of posted messages refers to the number of short messages actually delivered to the base station controller in the current time period. In order to balance the efficiency, the traffic sent by the two types of messages at this time is dynamically adjusted according to the traffic of the high-priority message and the normal message. The traffic of the two types of messages at a certain moment can be obtained as the actual number of delivered messages in real time; or the traffic submitted to the short message center at the historical moment of the high priority message (ie, the number of messages to be submitted) is used to estimate the current high priority message. Traffic, and the estimated traffic is subtracted from the segment threshold as the maximum allowed traffic at the current time of the normal message.

In the embodiment of the present invention, the determining module 40 is specifically configured to: when the short message that arrives is a high priority message, determine whether the actual number of delivery messages of the high priority message is smaller than the maximum traffic threshold of the number segment of the short message and the common message. The difference between the number of actual delivery messages; when the short message arrived is a normal message, it is determined whether the actual number of delivery messages of the ordinary message is less than the normal message threshold of the number segment of the short message, and is smaller than the maximum traffic threshold of the number segment of the short message and the maximum traffic threshold The difference between the actual number of delivery messages for the priority message. In this embodiment, a dynamic real-time calculation threshold is used for the high-priority message, the maximum traffic threshold is recorded as Max, and the high-priority message threshold is recorded as Imax, Imax=—the actual number of ordinary messages in the current time period, if the current time high-priority message is actually delivered. The number of messages <Imax, the high priority message can continue to be delivered. In order to ensure the smoothness of the message traffic, the sliding window mechanism is used to calculate the common message threshold, and the common message threshold of the current time period is estimated by the number of high priority messages to be delivered in the historical period. The following method is specifically adopted: Statistics before the current time period N The number of to-be-delivered messages of the high-priority message T1, Τ2 Τη, Ν is a natural number; the maximum traffic threshold Max of the number segment to which the short message belongs is obtained; the common message threshold Umax of the number segment of the short message in the current time period is determined. , the expression is: IImax=Max—(T1+T2+ +Tn)÷N. In this embodiment, Ν=3 is taken as an example to obtain the number of to-be-delivered messages T1, Τ2, Τ3 of the high-priority message in the first three time periods, that is, the MAC and the SP request to the short message center within three time periods before the current time period respectively. The number of high-priority messages submitted, the average traffic of high-priority messages in the three periods before the current time period is (Tl+T2+T3)÷3, then the common message threshold of the current time period nm _ax =Ma _X —(Tl+ T2+T3)÷3. The following conditions must be met to determine whether a normal message can continue to be delivered: The number of ordinary message delivery messages is <Πm _ax , and the number of normal delivery messages of normal-level messages <Max—the number of actual delivery messages of high-priority messages. This embodiment adopts a sliding window mechanism to ensure the smoothness of message traffic, and also ensures that high-priority messages are sent preferentially, taking into account the balance between flow control and delivery efficiency.

On the basis of the embodiment shown in FIG. 7, the feedback module 70 is added, wherein: the determining module 40 is further configured to: when the short message delivery fails, determine whether the delivery error code of the short message is the home location register error code. The statistics module 30 is further configured to: when the determining module 40 determines that the delivery error code of the short message is the home location register error code, decrement the number of actual delivery messages of the short message belonging number segment in the current time period by one; the feedback module 70 is set to When the determining module 40 determines that the delivery error code of the short message is the home location register error code, the short message is buffered, and the short message is fed back to the statistics module 30; when the determining module 40 determines that the delivery error code of the short message is not the home location register error When the code is coded, the short message is directly buffered, and the short message is fed back to the statistics module 30. In this embodiment, the short message center first queries the route by the HLR (Home Location Register) before sending the short message to the base station. If the HLR returns a failure when querying the route, such short message will not be delivered to the short message. The BSC does not affect the traffic of the base station, and can be deducted from the statistics of the actual delivery BSC. Therefore, it can be determined according to the error code returned by the core network whether it is a route failure returned by the HLR.
