Embodiment
Below the contrast accompanying drawing and in conjunction with embodiment the present invention is described in detail.
As shown in Figure 1, the distributed net element management system of the specific embodiment of the invention, it comprises following part:
Mission Control Center: the centralized control point that is mobile communication system distributed net element task.Mission Control Center can be positioned on the control module of network element, also can be positioned at the server end of operation maintenance center, and it is responsible for the network element task is issued, safeguarded, synchronously and control and management work such as renewal.Concrete, in the present embodiment, Mission Control Center comprises:
Task pool: be used for the placement task, be responsible for maintenance by Mission Control Center; By the setting of task pool, can provide the task buffering for the task of client terminal start-up, to improve system effectiveness; Simultaneously also can play certain safeguard protection to task.
Synchronous detecting control module: be used for task status is monitored maintenance, comprise regularly detection task, handle synchronization message and updating task pond.Certainly, the synchronous detecting control module as the task of the control centre that finishes the work detect, the unit of synchronizing function, it is from physical entity, no matter the form with the simple function unit exists, still exist as the part of certain integrated functionality unit, all suit.
Command executing node: be the Executive Module of control command, the terminal point that task is transmitted.After the control command of Mission Control Center sent to command executing node, the execution entity of command executing node was finished and the task status sign is set, the start/stop task operating.
Interface module: the intermediate transit point that is task.Although Mission Control Center also can directly issue task to command executing node, in the mobile communication system inside of complexity, task seldom directly is issued to the real execution body of task by Mission Control Center.Interface module plays the effect of task transfer, and the task that it sends Mission Control Center is forwarded to the command executing node of this task of execution.
In the specific embodiment of the invention, Mission Control Center is to the command executing node release tasks, and the task status of monitor command XM and carry out Synchronous Processing according to the task status of command executing node; The execute the task task of control centre issue of command executing node, and according to the Synchronous Processing result of Mission Control Center task is carried out synchronously.For this reason, behind task start, Mission Control Center is provided with and safeguards the task status list of an overall situation, this list records the task status of each command executing node, certainly, for the purpose of simple, also can only record the task status of the command executing node of task.Then, Mission Control Center and command executing node start regularly detection and tasks synchronization mechanism is carried out Synchronous Processing, and timing detection and the tasks synchronization mechanism to Mission Control Center and command executing node describes respectively below:
1. command executing node regularly detects and tasks synchronization mechanism
Mission Control Center to the monitoring of the task status of command executing node by command executing node initiatively report the task status of self to realize to Mission Control Center.Certainly, obtaining of the task status of command executing node also can be to be initiated by Mission Control Center, feeds back the task status of self and obtain order by the command executing node response.In this example, the mode that regularly reports has been adopted in the report of the task status of command executing node, and command executing node is reported the task status (whether task is arranged in operation, as do not have task then not need report) of oneself at set intervals to Mission Control Center;
How long command executing node oneself does not receive the syn ack of Mission Control Center (under the normal condition, behind the command executing node report condition, can receive the syn ack of Mission Control Center) if detecting simultaneously.Repeatedly do not receive syn ack, can think that then current task XM task status is unusual, command executing node stops current task, writes down current halted state, no longer carries out timed task and detects and tasks synchronization.
2. regularly testing mechanism and tasks synchronization mechanism of Mission Control Center
When having task to open, regularly the receive orders tasks synchronization message (reporting the task status of this command executing node) of XM of Mission Control Center.Mission Control Center enters the tasks synchronization treatment state, and this task status and local task status list are compared, and has task then to reply syn ack, does not have task then not process.
Local task status list regularly detects in Mission Control Center, for the command executing node of repeatedly not receiving synchronization message, can think that this command executing node may cause task to stop for a certain reason, can from local task status list, be made as halted state or remove this task and (write down all command executing node task statuses for task status list, need change into halted state; If task status list has only write down the command executing node that task is arranged, directly removing gets final product).
Be example with the reverse sensitivity test of 1x in the cdma wireless communication system below, the distributed net element task management of the specific embodiment of the invention is described in detail.
The reverse sensitivity test function of CDMA 1x is used for the demodulation ability of testing base station demodulation reverse signal, and wherein, the command executing node of test is positioned on the channel board of base station transceiver; Control board on the base station controller is as Mission Control Center; The control board of base station transceiver is as interface module.In cdma base station system, base station controller control board and base station transceiver control board are the relations of one-to-many, and base station transceiver control board and channel board also are the relations of one-to-many, and this has just constituted a complicated distributed system.
Oppositely sensitivity test starts flow process as shown in Figure 2:
1, after the control board of base station controller (Mission Control Center) is received the starting command of client, updating task status list (if first task, need initiating task to detect timer), and the control board of the base station transceiver that comprises in test assignment (interface module) sends initiation command; Wherein, when being judged as first task of unlatching, the task of then opening in the control centre detects timer, otherwise, then directly to the 2nd step.
2, after base station transceiver control board (interface module) is received beginning message, transmit initiation command to the channel board (command executing node) that task comprised;
3, after channel board (command executing node) is received initiation command, start test, and reply response message and give the control board (Mission Control Center) of base station controller [transmitting] by base station transceiver control board (interface module).If task is opened successfully, the task sign then is set, start synchro timer; If any operation is not carried out in the task start failure.Starting flow process finishes.
Oppositely sensitivity test tasks synchronization flow process is as shown in Figure 3:
1, the timing of the synchro timer on the channel board arrives, channel board is checked the task sign and is not replied counter, if do not have task or do not reply counter (in this example greater than pre-determined number, the pre-determined number value is 3, represent to send synchronization messages 3 times and do not receive response continuously, the pre-determined number value is not limited to 3, also can be the arbitrary value of presetting), then stop synchro timer, there is task then initiatively to initiate tasks synchronization message (transmitting), and will do not reply counter and add 1 by the base station transceiver control board to the base station controller control board.
2, after the base station controller control board is received the tasks synchronization message of channel board,, and reply syn ack message,, then do not reply and reply if there is not this task in this locality with the not coincidence counter zero clearing of corresponding task.
3, after channel board is received syn ack, with the not answer counter O reset of this locality.
Reverse sensitivity test task is testing process regularly:
1, the timing of the task of base station controller control board detection timer arrives, detect the not coincidence counter of all operation tasks in the current task status list, when this value of certain task during greater than pre-determined number (at this, the pre-determined number value is 3, represent the continuous synchronization message of not receiving the respective channels plate for 3 times), can think that the task of this channel board stops because of certain improper reason, directly removes from base station controller control board task list.
2, the synchronization times counter of all tasks adds 1.
Oppositely sensitivity test stop flow process as shown in Figure 4:
1, after the control board of base station controller is received ceasing and desisting order of client, remove the task that need stop from local task status list, all tasks all stop, need stop task and detect timer.The control board of base station controller also needs to stop message to the transmission of base station transceiver control board.
2, cease and desist order to the channel board forwarding after the base station transceiver control board is received and ceased and desisted order
3, after channel board is received and ceased and desisted order, stop synchro timer, will not reply counter O reset, the task status sign is set simultaneously, the task status of this locality is changed to no task status.
Certainly, the present invention is not limited only to the cdma base station subsystem, also is applicable to other distributed mobile communication system.Distributed net element task management of the present invention detects and synchronization mechanism by task status, guarantees that the task list of each command executing node reaches unanimity, and can solve because the problem that abnormalities such as information drop-out cause system resource to discharge.Not only stable, reliable, and be easy to realize.
Distributed net element task management method for the specific embodiment of the invention, it has comprised the workflow of above-mentioned execution on Mission Control Center and at least one command executing node, this workflow mainly comprises task issue implementation and tasks synchronization process, wherein, task issue implementation comprises: Mission Control Center is to the command executing node release tasks, and the execute the task task of control centre's issue of command executing node.
The tasks synchronization process comprises: the task status of Mission Control Center's monitor command XM, carry out Synchronous Processing according to the task status of command executing node; And command executing node is carried out task according to the Synchronous Processing result of Mission Control Center synchronously.
The tasks synchronization process has comprised that Mission Control Center and command executing node task separately detects, synchronously and information interaction between the two, for Mission Control Center, it can come the task status of monitor command XM by the task status of command executing node, and carries out Synchronous Processing according to the task status of command executing node:
To receiving the command executing node of its task status report, determine whether this command executing node has task, if any, reply syn ack, otherwise do not process;
To not receiving the command executing node of its task status report, determine whether this command executing node is unusual, in this way, the task of stopping this command executing node is carried out.
For command executing node, its Synchronous Processing result according to Mission Control Center carries out synchronously task, because under normal circumstances, command executing node will be received the syn ack of Mission Control Center after having made the coomand mode report, therefore, if can not receive the syn ack of Mission Control Center, illustrate that then the state of this task may be unusual, more accurate in order to judge, in this example, command executing node is set to:
When the syn ack of not receiving Mission Control Center surpasses (default arbitrary value can be adjusted as required) 3 times, determine that then this task status is unusual, stop this task and carry out.
In a word, the present invention is by the detection synchronization mechanism in Mission Control Center and the command executing node, avoid causing control command to be lost because of various factorss such as link physical situation, message transmission protocols, cause the not generation of first-class problem of operating state of a node, can significantly improve the reliability of system.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, but this example of just lifting for ease of understanding should not think that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can make various possible being equal to and change or replacement, these changes or replacement all should belong to protection scope of the present invention.
