The said method that utilizes present embodiment to provide can be determined the annexation between the main IF of using unit, standby IF unit and the data cell, thereby obtains the configuration protection relation of intermediate frequency unit.Further, in order to realize finding above-mentioned annexation automatically, in the said method, no matter be the main IF unit of using, still standby IF unit all can continue to send request message to data cell, and concrete steps are as follows:

The IF unit regularly sends request message to data cell by the Traffic Channel between self and the data cell at interval with default request time, and this request time can be set to different values at interval as required, as 3 seconds or 5 seconds or the like;

Correspondingly, data cell is after receiving the request message that the IF unit is sent, also can regularly return response message at interval with the default response time by above-mentioned Traffic Channel and give the IF unit, this response time also can be set to different values at interval as required, as 5 seconds or 10 seconds or the like;

In addition, no matter be the main IF unit of using, or standby IF unit, all can be after receiving the response message that data cell is returned, regularly send the ACK message to data cell with the default affirmation time interval, to confirm to have received the relevant information of data cell, this acknowledging time also can be set to different values at interval as required, as 5 seconds or 8 seconds or the like.

The process of the annexation between above-mentioned automatic discovery IF unit and the data cell can realize by state machine, particularly, can be at IF unit and state machine of each self-starting of data cell both sides, the switching by state realizes said process.Wherein, the state machine of IF unit maintenance comprises following one of four states:

1, initial state: request time tReq, response time interval tRes and acknowledging time interval tAck at interval are set, and with tRes and tAck zero clearing;

2, request Request attitude: the IF unit sends request message by Traffic Channel to data cell under this state, and transmission time interval is tReq, constantly sends the other times interval clear 0 that this moment will be except that tReq;

3, confirm the ACK attitude: the response message of the relevant information of carrying data cell that data cell is sent has been received in the IF unit under this state, sends the ACK message with the tAck time interval, can control the transmission rate of ACK message by tAck.

4, normal Normal attitude: the IF unit only detects the trigger condition of changing between this one of four states under this state, no longer initiatively outwards sends request message, and this trigger condition is specific as follows: 1. finish unimpeded access " request attitude " after the initialization; 2. after receiving the response message that carries the data cell relevant information that data cell sends, enter " affirmation attitude "; 3. in official hour T, do not receive the response message that data cell is returned, enter " normal state "; 4. the annexation that ought detect between IF unit and the data cell changes, as changed netting twine between IF unit port and the data unit port, make port connect and disconnect (linkdown), perhaps receive the control command of annexation between change IF unit and the data cell, when intervening, enter " initial state " as control command artificially is set.Wherein, official hour value T preferably can be set to T 〉=3 * tAck.For example, the tAck value is 5 seconds, and then T is set to 15 seconds or 20 seconds or the like.

As shown in Figure 9, be the conversion schematic diagram between the above-mentioned one of four states in IF unit.The IF unit can be changed between initial state, request attitude, affirmation attitude and normal state according to above-mentioned four trigger conditions.Wherein, several conversions below the existence: initial state-＞the request attitude, the request attitude-＞the affirmation attitude, the affirmation attitude-＞normal state, normal state-＞initial state, the affirmation attitude-＞initial state-＞, and the request attitude-＞initial state.

The state machine that data cell is safeguarded comprises following two states:

1, response Response attitude: data cell has been received the request message that the IF unit is sent under this state, and the Response message that sends the relevant information (containing data cell sign, groove bit-identify, port information etc.) of carrying data cell with the tRes time interval is to the IF unit;

2, normal Normal attitude: data cell only detects the trigger condition of changing between these two states under this state, does not initiatively send response message, and this trigger condition is specific as follows: 1. receive the request message that the IF unit is sent, enter " response attitude "; 2. receive the ACK message of sending the IF unit, stop to send response message, enter " normal state ".

As shown in figure 10, be the conversion schematic diagram between above-mentioned two states of data cell.Data cell can be changed between response attitude and normal state according to above-mentioned two trigger conditions.That is: the response attitude-＞normal state and normal state-＞the response attitude.

The said method that present embodiment provides has improved the flexibility of setting up the protection of active and standby intermediate frequency unit, has been convenient to management.By the Traffic Channel transmitting control message (comprising request message, response message and confirmation message) between IF unit and the data cell; can realize that the IF unit obtains the relevant information of data cell; thereby determine the port annexation between IF unit and the data cell; by regularly sending automatic discovery and the Dynamic Maintenance that the control message can be realized above-mentioned annexation at interval according to Preset Time; thereby when finishing two unit matching, the automatic foundation of active and standby intermediate frequency unit protection.Make the user can only pay close attention to the configuration of IF unit, and with the data cell of IF unit matching can by the present invention finish automatic discovery and and configuration automatically, and can guarantee to control the reliable delivery of message.Above-mentioned control message is the OAM message, can realize easily by obtaining after the OAMPDU expansion, and is simple and convenient.Utilize state machine to realize controlling message and periodically transmit, speed that can such message of control transmission has improved ease for use, is convenient to administer and maintain.

And whether the application of said method is not limited to the annexation of IF unit and data cell fixing, and promptly no matter this annexation is fixed, and is still unfixed, all can use said method.When this annexation changes,, can obtain new annexation by restarting automatic discovery procedure; when noting be used in each annexation and changing; all reconfigure the main-apparatus protection of intermediate frequency unit, thereby greatly improved configuration flexibility, conveniently administer and maintain.
