(4) in official hour, if receiving described the setting, the EoC head end confirms bag, enter step (8) if the EoC head end does not receive to arrange and confirm bag, enter step (5);

(5) the EoC head end checks whether surpass maximum number of retransmissions, if also do not surpass maximum number of retransmissions, enters step (6), if surpass maximum number of retransmissions, enters step (7);

(6) the EoC head end is retransmitted parameter and packet is set to this WIFI functional module, enters step (3);

(7) the EoC head end indicates that in database this WIFI functional module arranges fail flag for attendant's inquiry, enters step (8);

(8) process ends.

Obtain flow process or parameter arranges in the flow process in data, the data of WIFI functional module are obtained or parameter setting when relating to concrete parameter, data load partly defines content by the mode of ordering in the management agreement, and when adopting one instruction is set comprises a plurality of parameter, for distinguishing the parameter that needs setting, partly add the state bitmap at index part or data load, utilize each corresponding parameter of binary number, can not change by putting 0 expression parameter, put 1 expression parameter variation has taken place, the WIFI functional module only chooses by this state bitmap that the parameter that changes is obtained or the parameter setting.

Code upgrade or configuration file upgrading flow process may further comprise the steps:

(1) the EoC head end splits into upgrade file behind the instruction that receives the upgrading WIFI functional module that the upper strata remote management interface sends over and upgrade file and meets some parts of managing protocol requirement, and first set up into upgrading data packet, wherein the index part of upgrading data packet hangs down 15 bit representation packet current sequence number, be set to 1, the index part highest order represents to send mark, be set to 0, command component writes download command, sends this upgrading data packet to the WIFI functional module that needs upgrading;

(2) the WIFI functional module receives this upgrading data packet, extracts the current sequence number in the index part, and judges that whether this sequence number is 1, if expression is first packet, enters step (3); If this sequence number is not 1, judge whether current sequence number+1 value into a last AKU, if, enter step (3), if not, then occur packet loss in the escalation process or make mistakes process ends;

(3) the WIFI functional module is returned a upgrading affirmation bag to the EoC head end, data load content in the described upgrading data packet is set up file according to the current sequence number of index part, and the highest order of judging index part whether 1, if 1, the expression upgrade file is end of transmission, the WIFI functional module is carried out updating operation by the file type of downloading, if for example downloaded files is code upgrade file then programming flash, if downloaded files is configuration file then transaction file system etc., process ends, if the highest order of index part is 0, represent that then file does not have end of transmission, the WIFI functional module continues to wait for the next upgrading data packet of reception;

(4) in official hour, if receiving to upgrade, the EoC head end confirms bag, enter step (5), if the EoC head end is not received upgrading affirmation bag, enter step (6);

(5) the EoC head end is set up into next upgrading data packet to the next part of upgrade file, wherein the current sequence number that writes of index part is current sequence number+1 of a last upgrading data packet, and judge whether to be the last part upgrade file, if the highest order of putting this upgrading data packet index part is 1, send to the WIFI functional module, enter step (2), if not the highest order of this upgrading data packet index part still puts 0, send to the WIFI functional module, enter step (2);

(6) the EoC head end judges whether to surpass the maximum number of retransmissions of setting, if do not surpass, enters step (7), if surpass, enters step (8);

(7) the EoC head end is retransmitted upgrading data packet, enters step (2);

(8) upgrading failure, EoC head end indicate that in database the upgrading fail flag is for attendant's inquiry, process ends.

In code upgrade or configuration file upgrading flow process, the file download function that management agreement is supported comprises: (a) specify download function and batch download function, specify download function to download for specifying a WIFI functional module, this appointment download is adopted the WIFI functional module to reply the affirmation mode and is guaranteed transmission reliability, described batch is downloaded to specifying all online WIFI functional modules to download, this download in batches adopt the EoC head end to same message repeatedly send, the WIFI functional module abandons the follow-up mode of the message of same index of receiving and guarantees transmission reliability; (b) normally download and force download, under normal download situation, the identifying information that the WIFI functional module issues before download the EoC head end is when existing validation of information consistent, no longer carry out updating operation, under the force download command situation, the WIFI functional module no matter the identifying information that before download, issues of EoC head end whether with have the consistent updating operation again of all taking of information.

Fig. 4 is a software frame of the embodiment of the invention.As shown in Figure 4, the management agreement of the operation of EoC head end master chip and the communication of WIFI functional module is put into database to the data that obtain; Run on the application program such as SNMP, WEB, CLI of EoC head end as required, from database, obtain relevant information.When application programs such as SNMP, WEB, CLI obtain tension management software order is set the time, the data of being correlated with are put into database; EoC head end operational management agreement is obtained from database and relevant data be set and send to the setting of being correlated with of WIFI functional module.

The EoC terminal module of the wireless EoC terminal in the embodiment of the invention is applicable to all EoC schemes, and plate or connected modes such as MII butt joint or PHY butt joint are adopted in being connected of EoC terminal module and WIFI functional module.

The present invention since the management agreement of EoC head end by special use realized carrying out alternately with the WIFI functional module and with the connected EoC terminal module of WIFI functional module related make both manage into as a whole, by the telemanagement of tension management interface realization to wireless EoC terminal, finally effectively solved in the present EoC technology terminal WIFI unified management problem partly again.
