Below in conjunction with the drawings and specific embodiments the present invention is further detailed.
May be inconsistent at the foreground and background data that present gsm system or cdma system exist, and the user's situation that can't monitor and confirm the consistency of foreground and background data, the present invention with the CRC algorithm application in foreground and background data is carried out on the consistency desired result.The consistency desired result function can be calculated the crc value of the tables of data on switch foreground and backstage respectively, behind the crc value that calculates more respectively comparative result is shown to the user.The information that shows is the consistency situation of foreground and background data, can also point out user data inconsistent title when inconsistent, be convenient to the user and check and reset, thereby the consistency of assurance foreground and background data is guaranteed the normal operation of switch.
With the consistency desired result process under three kinds of situations the present invention is specifically described below.
Specific embodiment 1
Set into the foreground in back-end data, when just the switchboard background data setting being gone into the switch foreground, can carry out consistency desired result automatically, whether consistent with switch Foreground Data in the process that check to set configuration data with data in the back-end data table, and the result is presented on the data management client platform, user result in view of the above judges the correctness of the data of setting.Its concrete checking procedure comprises that step 201 as shown in Figure 2 is to step 213.
Step 201: data management client platform judges whether current table has data to be modified.If there are data to be modified, then point out the user whether will preserve the data record of current modification.If the user need preserve the data record of current modification, then preserve earlier; If do not need to preserve the data record of current modification, then abandon preserving, the data in the tables of data still are initial data at this moment.Then this tables of data is sent to switchboard background.
Step 202: data management client platform is to the order of switchboard background transmission setting data, and the setting command here can only be set the wall scroll data record, also can set the data record of whole tables of data.When sending the setting data order, send the CRC order.
Step 203: data management client platform starts the response timeout timer.
Step 204: switchboard background is after the order of the setting data that receives the transmission of data management client platform, and conversion needs the data of setting, just converts a binary file to.If exception code is then returned in the translation data failure,, and withdraw from checking procedure to the user prompt error message; If change successfully, carry out next step.
Step 205: switchboard background sends the setting data order to the switch foreground, sends the CRC order simultaneously.
Step 206: after the switch foreground receives the setting data order, to the response message of switchboard background transmission to the data setting command.
Step 207: switchboard background sends the data that need setting to the switch foreground, just the binary file that forms in the step 204.
Step 208: the switch foreground receives data to be set earlier, after all Data Receiving finish, refreshes static database and preserves the tables of data data record.
Except in step 202 and step 205, sending simultaneously the CRC order with the order of transmission setting data, the setting data process of above-mentioned other processes and prior art is as broad as long, in order to carry out consistency desired result to foreground and background data, characteristics of the present invention are to have increased transmission CRC order in step 202 and step 205, and have increased following steps:
Step 209: switchboard background calculates the crc value of switchboard background data.
Step 210: the crc value of the tables of data data of preserving is calculated on the switch foreground in step 208.
Step 211: the switch foreground sends to switchboard background with the crc value that calculates in the step 210 according to consolidation form.
Step 212: the crc value that crc value that switchboard background is beamed back the switch foreground and switchboard background calculate compares, and the record comparative result.
Step 213: result relatively returns to data management client platform with step 212, and this comparative result is shown to the user.
Said process carries out at a module, data record of She Dinging or tables of data are included in a plurality of modules if desired, then need be at each module repeated execution of steps 204 to step 212, the comparative result with the data record of all modules in step 213 is shown to the user.If confirm the foreground and background data unanimity through CRC check, will directly show the verification unanimity so.If find that foreground and background data is inconsistent, will be to the inconsistent module No. of user prompt.The user if find that the foreground and background data of some modules is inconsistent, then may be that mistake appears in assignment procedure after reading display result, and this moment, the user can carry out the data setting operation again, to guarantee the consistency of foreground and background data.
Specific embodiment 2
If in the running on switch foreground, break down, mistake appears in the data record that might be the switch foreground so, in this case, in order to check mistake apace, some data that also needs the comparison switchboard background whether with the switch foreground in the data consistent preserved.If it is owing to error in data in a certain the concrete tables of data causes the fault on switch foreground that the user suspects, this moment, the user can access this tables of data at data management client platform, and the interactive interface by data management client platform selects " this table of verification " order, thereby single table is carried out verification.Its concrete checking procedure comprises that step 301 as shown in Figure 3 is to step 312.
Step 301: the user selects " this table of verification " order, input command parameter simultaneously by the interactive interface of data management client platform: the module numbering that needs verification.
Step 302: data management client platform judges whether current table has data to be modified.If there are data to be modified, then point out the user whether will preserve the data record of current modification.If the user need preserve the data record of current modification, then preserve earlier; If do not need to preserve the data record of current modification, then abandon preserving, the data in the tables of data still are initial data at this moment.Then this tables of data is sent to switchboard background.
Step 303: data management client platform is to the order of switchboard background transmission CRC check, and command parameter has tables of data identifier (ID), number of modules and module numbered list.
Step 304: whether switchboard background is judged has other client's platform that this table is being carried out verification operation, if there is other client's platform also this table to be carried out verification operation, then points out other client's platform of user that this table is being operated, and withdraw from checking procedure this moment.If do not have other client's platform that this table is operated, then carry out next step.
Step 305: data management client platform starts the response timeout timer.
Step 306: switchboard background is after the CRC order that receives the transmission of data management client platform, and the record data of this table of conversion just convert thereof into a binary file earlier.If exception code is then returned in the translation data failure,, and withdraw from checking procedure to the user prompt error message; If change successfully, carry out next step.
Step 307: switchboard background sends the CRC order to the designated module on switch foreground, and command parameter has tables of data ID.
Step 308: switchboard background calculates the crc value of the data message of the binary file that it preserves.
Step 309: after the switch foreground receives the CRC order of switchboard background transmission, calculate the crc value of these tables of data data of preserving in the switch foreground.
Step 310: the switch foreground sends to switchboard background with the crc value that calculates in the step 309 according to consolidation form.
Step 311: the crc value that crc value that switchboard background is beamed back the switch foreground and switchboard background calculate compares, and the record comparative result.
Step 312: result relatively returns to data management client platform with step 311, and this comparative result is shown to the user.
Said process carries out at a module, if desired same tables of data in a plurality of modules carried out verification, when step 301 input command parameter, can import the numbering of a plurality of modules so respectively, perhaps select the numbering of a plurality of modules by the drop-down menu of interactive interface.This moment will be at each module repeated execution of steps 306 to step 311, and the comparative result with the data record of same tables of data of all modules in step 312 is shown to the user.If confirm the foreground and background data unanimity through CRC check, will directly show the verification unanimity so.If find that foreground and background data is inconsistent, will be to the inconsistent module No. of user prompt.The user if find that this table foreground and background data of some modules is inconsistent, can carry out the data setting operation, to guarantee the consistency of foreground and background data again after reading display result.
Specific embodiment 3
Under the situation about in the running on switch foreground, breaking down, mistake occurs, can select all tables are carried out consistency desired result if which data the user can not determine.This moment, the user can select " verification is whole " order by the interactive interface of data management client platform, thereby all tables of data are carried out verification.Its concrete checking procedure comprises that step 401 as shown in Figure 4 is to step 412.
Step 401: the user selects " verification is whole " order, input command parameter simultaneously by the interactive interface of data management client platform: the module numbering that needs verification.
Step 402: data management client platform judges whether current table has data to be modified.If there are data to be modified, then point out the user whether will preserve the data record of current modification.If the user need preserve the data record of current modification, then preserve earlier; If do not need to preserve the data record of current modification, then abandon preserving, the data in the tables of data still are initial data at this moment.Then this tables of data is sent to switchboard background.
Step 403: data management client platform sends to switchboard background all tables is carried out the order of CRC check, and command parameter has the module numbering.
Step 404: whether switchboard background is judged has other client's platform that this table is being carried out verification operation, if there is other client's platform also this table to be carried out verification operation, then points out other client's platform of user that this table is being operated, and withdraw from checking procedure this moment.If do not have other client's platform that this table is operated, then carry out next step.
Step 405: data management client platform starts the response timeout timer.
Step 406: switchboard background receive that data management client platform sends all tables are carried out the order of CRC check after, conversion is the record data of table all, just convert a binary file to.If exception code is then returned in the translation data failure,, and withdraw from checking procedure to the user prompt error message; If change successfully, carry out next step.
Step 407: switchboard background carries out the order of CRC check to the designated module transmission on switch foreground to independent table, and command parameter has tables of data ID.
Step 408: switchboard background calculates the crc value of the data in this tables of data in the binary file that it preserves.
Step 409: the crc value of data in this tables of data of preserving in the switch foreground is calculated on the switch foreground.
Step 410: the switch foreground sends to switchboard background with the crc value that calculates in the step 409 according to consolidation form.
Step 411: the crc value that crc value that switchboard background is beamed back the switch foreground and switchboard background calculate compares, and the record comparative result.
To step 411, compared the crc value of a certain independent tables of data of AM/BAM in step 407, owing to need carry out verification to all independent tables of designated module, so necessary repeated execution of steps 407 is to step 411.
Step 412: the comparative result of step 411 pair all tables of data is returned to data management client platform, and this comparative result is shown to the user.
If confirm the foreground and background data unanimity through CRC check, will directly show the verification unanimity so.If find that foreground and background data is inconsistent, will be to the ID of inconsistent module No. of user prompt and tables of data.The user if find to have the inconsistent situation of crc value of AM/BAM calculating, can carry out the data setting operation, to guarantee the consistency of foreground and background data again after reading display result.
In the above among three embodiment, the switch foreground can be { a table number to the unified message form that switchboard background sends, crc value, error code }, the table number ID of the tables of data of verification this time just wherein, crc value are exactly the crc value of this tables of data of calculating of switch foreground, and error code represents this time to calculate whether success, if be 0 expression calculates successfully, if other value then expression calculating fail.For error code is not 0, and just the situation of failure is calculated on the switch foreground, and then this time checking procedure finishes, and is prompted to the user, and the user can select this tables of data is reset.For example a message format is that { 2,234,0} represents that then this tables of data ID is 2, and the crc value that the switch foreground calculates is 234, and it is success and effective that this crc value calculates.
In the above among three embodiment, if whether display result is not consistent, but Exception Type, for example, when switchboard background sent the crc value that calculates, data management client platform can receive a corresponding temporal information on the switch foreground, if it is overtime that this temporal information has exceeded the predetermined response to of response timeout timer, data management client platform will return Exception Type so, and this moment, the user need carry out the data setting operation equally again, to guarantee the consistency of switch foreground and background data.
Above-mentionedly the present invention is had been described in detail, but be appreciated that they only are used for the present invention is made an explanation, and be not intended to limit the scope of the invention by three specific embodiments.
