Below respectively from the angle of system and method to the present invention's elaboration of giving an example.
Specifically, for system of the present invention, message sends platform as the core component in system, and as shown in Figure 4, its internal module can comprise: task control thread, route analysis thread, message send-thread group.
Wherein, the task control thread is mainly used in creating in real time the task that issues, extracting task objective number, real-time update task status function.
The task that issues and destination Mobile Station International ISDN Number that the route analysis thread is mainly used in being responsible for inputting carry out route analysis according to route information table, and according to the corresponding relation of the prefix section in route information table, downstream node ID and queue ID to be sent, the destination Mobile Station International ISDN Number extracted by the task control thread is carried out to route analysis, then corresponding destination Mobile Station International ISDN Number is put into to queue to be sent corresponding to this area.Here it is to be noted: the destination Mobile Station International ISDN Number of different prefix sections is put into respectively different queue classification storages to be sent, and different queues to be sent is corresponding to different downstream nodes.Because downstream node is distinguished according to area, therefore, like this, in subsequent operation, queue to be sent is under the control of message send-thread, just can extract the destination Mobile Station International ISDN Number of a certain prefix section of correspondence that queue to be sent carries, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction.Thereby by the routing policy of prefix section, the message equilibrium is issued to each downstream node, is particularly useful for processing for the flow equalization under the scene of the national platform issuing service of a plurality of downstream nodes.
Message send-thread group is mainly used in being responsible for receiving each queue to be sent of input, the current flow situation according to each downstream node, according to the flow equalization principle, extract the destination Mobile Station International ISDN Number of storing in queue to be sent, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction.
Specifically, for method of the present invention, the realization flow of the inventive method mainly comprises following several respects content:
One, system creation N queue to be sent, the establishment of now queue to be sent is actually the establishment principle according to the form of queue to be sent, first create empty queue to be sent, during follow-up the sequence, just by the data destination Mobile Station International ISDN Number, be added in the queue to be sent of the corresponding sky created.
Here, the information that queue to be sent comprises can comprise: issue mission bit stream, nodal information, destination Mobile Station International ISDN Number district, last time and issue skew, sending flow rate etc.Queue to be sent completes and task is realized to the classification storage of destination Mobile Station International ISDN Number according to downstream node, follow-up, the message send-thread, by issuing the start offset number that deviation post determines each transmission the last time of queue to be sent, determines the destination address issued by nodal information.Wherein, nodal information can be downstream node ID.
Two, create route information table.
Here, the information that route information table mainly comprises has: the queue ID to be sent of prefix section, downstream node ID, correspondence.Route information table is disassembled for the destination Mobile Station International ISDN Number of task, and whenever a task creation, the task control thread carries out route analysis to each destination Mobile Station International ISDN Number successively, then corresponding destination Mobile Station International ISDN Number is joined in queue to be sent.
Three, the task control thread has been analyzed all destination Mobile Station International ISDN Number of task, and the request message that will sort sends to the route analysis thread, and notice route analysis thread is sorted.
Four, the route analysis thread, according to the mapping table of number segment and downstream node, carries out the creation operation of queue to be sent, and creation operation now is: be destination Mobile Station International ISDN Number by data, be added in the queue to be sent of the corresponding sky created before.For example number 13594200001 needs to send, the corresponding downstream node of number segment 1359420 number is 3, at first the route analysis thread checks that whether having remained transmit queue for node number 3 these tasks has created, if have, 13594200001 numbers are joined to the end of corresponding queue to be sent; If do not have queue to be sent to be created, create a new queue to be sent, corresponding downstream node number is 3.The rest may be inferred, completes the sorting operation to all destination Mobile Station International ISDN Number.After the sequence flow processing, queue to be sent is sent to each message send-thread, notify each message send-thread to start to carry out transmission flow.
Five, the message send-thread adopts the mode that multi-threaded parallel is processed, if queue to be sent add up to N; The numbering of each queue to be sent is respectively: 0..N-1; The quantity of message send-thread is M, and N >=M; A plurality of queues to be sent of each message send-thread management, by MOD(queue ID to be sent, M) calculate the control relation between message send-thread and its queue to be sent of controlling, and controlled each queue assignment to be sent to corresponding message send-thread.For example, the sum of queue to be sent is 10, and the sum of message send-thread is 5, and No. 0 message send-thread can be controlled queue 0,5 to be sent; No. 3 the message send-thread can be controlled queue 3,8 to be sent.
Here, when message sends, at first the message send-thread need to check the flow of corresponding downstream node, issue condition if meet flow, the current message send-thread extracts a destination Mobile Station International ISDN Number from queue to be sent, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction.And whether the flow that all needs to detect current downstream node after issuing issues condition and still meets at every turn.In practice, usually after the current message send-thread selects its queue to be sent controlling to issue the message of some, should forward immediately the next queue to be sent of being controlled by this current message send-thread to is issued, the rest may be inferred, the scale factor sent according to message selects the destination Mobile Station International ISDN Number of suitable number at every turn from queue to be sent, and message is issued to the downstream node in the current corresponding area of destination Mobile Station International ISDN Number of choosing.Wherein, for scale factor, every scale factor issued of taking turns adopts the flow proportional of each downstream node to obtain.
Below, adopt message as shown in Figure 4 to send platform, describe implementation method of the present invention and handling process in detail, the mode adopted here is to utilize internal storage to create queue to be sent, this handling process comprises the following steps:
Step 101: system starts and initialized process.
Here, when system starts, application has a certain size internal storage, creates N queue to be sent in internal storage, for each queue to be sent is numbered 0 to N-1, is: the form of queue to be sent is set, and creates empty queue to be sent.The open ended destination Mobile Station International ISDN Number of each queue to be sent is several to be sent according to message the order of magnitude that platform can send message and is configured.Wherein, the relevant information that the size of internal storage need to be carried by task and platform send the order of magnitude equilibrium of message to downstream node to be determined, and the restriction of the internal memory of machine is determined.
Create queue to be sent except needs when system startup and initialization, also need to create M message send-thread, and M is less than or equal to N.Create route information table, read route data.Route data mainly comprises prefix section, node ID and corresponding queue ID to be sent, and the parameters such as scale factor of destination Mobile Station International ISDN Number are extracted in each queue to be sent at every turn.
When initialization, also need to calculate the control relation between message send-thread and downstream node number.Such as message sends platform, 10 message send-threads, M=10 are arranged; And 20 downstream nodes, N=20.Remainder after downstream node MOD10 determines this downstream node by which message send-thread is controlled and processed.Such as No. 1 message send-thread control No. 1 and No. 11 downstream nodes, No. 8 the message send-thread is controlled No. 8 and No. 18 nodes, by that analogy.Here it is to be noted: because queue to be sent and downstream node are corresponding, therefore, also can calculate the relation between message send-thread and its queue to be sent of controlling, by MOD(queue to be sent ID, M) controlled each queue assignment to be sent to corresponding message send-thread.Like this, by the corresponding relation of queue to be sent and downstream node, the destination Mobile Station International ISDN Number of a certain prefix section of the follow-up correspondence that just transmit queue can be carried under the control of message send-thread, send to corresponding regional downstream node.
Step 102: the task control thread creates in real time message and issues task.
Here, creation task comprises: the basic task information such as the time that issues of (1) task, calling number, charging policy; (2) all purpose Subscriber Numbers.Mission bit stream passes to the route analysis thread by task after creating.
Step 103: the route analysis thread receives new task, route data according to storage inside, comprise prefix section and corresponding purpose downstream node ID thereof, difference according to downstream node number creates out a plurality of queues to be sent, and all destination Mobile Station International ISDN Number of task are carried out after route analysis, number being stored in corresponding queue to be sent.
Here, being: according to the route data of storing in route information table, by data--destination Mobile Station International ISDN Number is added in the queue to be sent of the sky established in step 101 successively.
Step 104: after the complete all destination Mobile Station International ISDN Number of route analysis thread process, the task of each downstream node of correspondence that the route analysis thread creation is gone out sends to corresponding message send-thread, and notifies each message send-thread to start to carry out transmission flow.
Step 105: message send-thread, at first check the flow of corresponding downstream node, issue condition if meet flow, a queue to be sent of controlling from it, extract a destination Mobile Station International ISDN Number, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction.And whether the flow that all needs to detect current downstream node after issuing issues condition and still meets at every turn.After selecting certain downstream node to issue some message, should forward immediately next queue to be sent to and be issued, the rest may be inferred.
Here, the work of No. 1 message send-thread of take is example: No. 1 message send-thread first checks the message traffic of No. 1 corresponding downstream node of queue to be sent, if flow does not surpass restriction, just from queue to be sent, take out a destination Mobile Station International ISDN Number, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction, record the skew that this sends message after sending successfully, and then inspection message transmitted traffic, after flow surpasses restriction or after processing messages number this processing messages parameter factors over setting, start to process No. 11 queues to be sent.Processed No. 11 queues to be sent later again poll return and process No. 1 queue to be sent.Each message send-thread repeats identical message and sends task, until all Subscriber Numbers all are sent out.Because be the simultaneously conditional message sent to a plurality of downstream nodes, thereby instantaneous load and the impulsive force of downstream node have been reduced.
In sum, message that the present invention discusses sends platform when connecting a plurality of Short Message Service Gateway/MMS center message Batch sending, routing policy according to the prefix section, destination Mobile Station International ISDN Number is carried out to control of queue, each node is created to a plurality of queues to be sent, poll ground a plurality of node issuing messages downstream, can reduce energetically the engineering cost that note/multimedia message sends platform, alleviate the load of Short Message Service Gateway/MMS center, the efficiency of raising system, realize as far as possible using conventional network resources, enhance the competitiveness.
Below application processing procedure of the present invention on whole nation level mobile newspaper platform is described as follows:
At first, start service processor.Service processor reads relevant configuration information, and here, relevant configuration information comprises the number N=20 of queue to be sent, the number M=10 of message send-thread; A certain size internal memory of service processor application creates 20 queues to be sent and 10 message send-threads in internal memory.Create route information table, read route data, route data is recorded in internal memory.And the message send-thread that creates other.
Secondly, the initial message send-thread, and calculate the control relation between message send-thread and queue to be sent.Remainder after queue number MOD10 to be sent determines which message send-thread this is controlled and process by by queue to be sent.Corresponding relation due to queue to be sent and downstream node, therefore, according to the message send-thread calculated and the relation of thread to be sent, the corresponding relation of outbound message send-thread and downstream node: for example: No. 1 message send-thread control No. 1 and No. 11 downstream nodes, No. 8, No. 8 Thread controls and No. 18 downstream nodes.
Then, upgrade the mobile phone newspaper content, trigger processor establishment mobile phone newspaper and order the task that issues.This generic task has magnanimity purpose Subscriber Number.
Further, the task control thread reads task, and the route analysis thread, according to all destination Mobile Station International ISDN Number of the complete task of routing iinformation table analysis, becomes a plurality of little tasks by Task-decomposing, then request message is sent to each message send-thread, notify each message send-thread to start the transmission task.
Finally, the message send-thread starts to send task by configuration parameter.At first check the flow of corresponding downstream node, issue condition if meet flow, from queue to be sent, extract a destination Mobile Station International ISDN Number, and message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number of current extraction, record the skew that this sends message after sending successfully.After issuing, all need the flow condition that detects current downstream node whether to meet at every turn, after flow surpasses restriction or after processing messages number this processing messages parameter factors over setting, should forward immediately next queue to be sent to is issued, the rest may be inferred, until task sends, finishes.
A kind of method that realizes that the flow equalization to a plurality of downstream nodes issues, the method comprises: adopt prefix section routing policy to realize that the equilibrium of sending flow rate controls, and according to destination Mobile Station International ISDN Number, message is issued to the downstream node in the corresponding area of destination Mobile Station International ISDN Number.
Here, can send platform by message and send a message to downstream node.After sending a message to downstream node, can also comprise: by downstream node, message is offered to the destination Mobile Station International ISDN Number user.Here, message sends platform and sends to downstream node: send to the message of downstream node according to various host-host protocols, the message the inside at least includes message content and destination Mobile Station International ISDN Number, and wherein message content can be specially short message content or MMS content.
The above-mentioned concrete processing procedure that sends a message to downstream node comprises the following steps:
Step 2011: the task that task control thread creation message sends, and extract destination Mobile Station International ISDN Number corresponding to task.
Here, destination Mobile Station International ISDN Number can adopt the form of destination Mobile Station International ISDN Number list to exist.
Step 2012: the route analysis thread carries out route analysis according to route information table to destination Mobile Station International ISDN Number, and by each destination Mobile Station International ISDN Number of corresponding different regions number segment, correspondence is added in different queues to be sent the storage of classifying respectively.
When here, route information table and different queues to be sent are initialization, created.While carrying out route analysis, can carry out one by one route analysis to destination Mobile Station International ISDN Number according to the route information table created, after analysis finishes, by each destination Mobile Station International ISDN Number of corresponding different regions number segment, correspondence is added in the different queue to be sent created the storage of classifying respectively.
