The Correspondent Node configuration information obtaining method that the embodiment of the invention one provides, its flow process comprises the steps: as shown in Figure 1
Step S11: receive the Frame that peer node equipment sends.
The configuration information corresponding codes of carrying the opposite equip. interface in the Frame that the peer node equipment that node device receives sends.Peer node equipment writes the configuration information of self in the Frame, specifically can write in the reservation position of Frame, sends the Frame node device then.
Configuration information can comprise one of following message or combination: clock source, clock module, framing format, link tunneling, the requirement of opposite end loop configuration, line coding mode, bell idles and upper-layer service configuration; Accordingly, the different corresponding codes differences of the attribute of information that comprises in the configuration information and/or information.It is the corresponding different coding of each possible configuration information.
The flow process of node device or peer node equipment sending data frame as shown in Figure 2, after having disposed its own interfaces configuration, determine interface configuration information corresponding codes, can inquire about the every kind of possible configuration information of local storage in advance and the corresponding relation of coding, chip register is set, coding is write in the reservation position of Frame, send Frame then.
Step S12: from the Frame that receives, obtain the coding that carries.
Node device can be resolved receiving Frame, obtains the coding that carries from the reservation position of Frame.
Step S13: determine efficient coding according to the coding that obtains.
Node device can be determined efficient coding according to the coding that gets access to from a Frame.Preferably, also can be according to the coding that from set the quantity data frame, obtains, determine efficient coding, obtain the coding that carries this moment successively from the setting quantity data frame that receives, when the coding that carries in the setting quantity data frame that receives is all identical, determine the efficient coding that is encoded to that gets access to.
Step S14: inquire about the coding of local storage and the corresponding relation of configuration information, determine the configuration information of efficient coding correspondence.
Node device is local can every kind of possible configuration information of storage and the corresponding relation of coding, when the efficient coding of carrying in the Frame that gets access to the transmission of peer node equipment, can learn the configuration information of efficient coding correspondence by inquiring about this corresponding relation.
Step S15: the configuration information that obtains the peer node equipment interface.
The configuration information of above-mentioned efficient coding correspondence is the configuration information of peer node equipment.
Preferably, obtain also comprising after the configuration information of peer node equipment interface: judge whether peer node equipment has the configuration response demand, when being judged as when being the configuration needs of response peer node equipment.
Preferably, monitoring that node device can be real-time in the said method and receiving alarm signal when receiving alarm signal, end to obtain the flow process of peer node device configuration information.This is because when having alarm, it is invalid or wrong that the configuration information that gets access to is likely.
Preferably, before the above-mentioned steps S12, can also comprise judging whether that needs start the flow process of obtaining the peer node device configuration information.When judge to need starting, execution in step S12 again, otherwise, not execution in step S12 and subsequent step.
In the said method, at the E1 communication technology, according to ITU standard G.704, the frame format of the Frame of its CE1 pattern can have two kinds: the multi-frame form of dual-frame format and the verification of band cyclic redundancy check (CRC) code (crc), i.e. no-crc form and crc form.
Wherein the frame format of dual-frame format (no-crc form) comprises two basic frame: Frame0 and Frame1 as shown in Figure 3; The time slot 0 of these two basic frames (Time slot 0) is a frame head, is used for the definition frame form, and 31 follow-up time slots (Time slot 1-Time slot 31) are used to transmit data.
Wherein, the Si in the frame head information is the international position that keeps, and puts 1 when not using; A is the remote alarm position; Sa4-Sa8 is for keeping the position, and the time spent does not put 1, uses as expansion in the present invention, is used to carry interface configuration information corresponding codes.
Wherein with the frame format of the multi-frame form (crc form) of crc verification as shown in Figure 4, comprise two Sub Multiframes, each Sub Multiframe comprises 8 basic frames.Wherein, the C1-C4 in the frame head information is the crc check digit; E is spare international position or error indication bit; A is the remote alarm position; Sa4-Sa8 is for keeping the position, and the time spent does not put 1, uses as expansion in the present invention, is used to carry interface configuration information corresponding codes.
Mainly utilize the reservation position Sa4-Sa8 in the frame format to carry encoded radio in the said method of the present invention, realize the mutual of the configuration of interface of two end node devices and demand information.Wherein, keep position Sa4-Sa8 and write different codings, represent different semantemes.When sending, be respective coding according to the interface configuration information setting Sa4-Sa8 position of this end node devices.When receiving, read the coding that comprises in the configuration codes table that value that the relevant chip register obtains the Sa4-Sa8 position can preserve with this locality and the corresponding relation of configuration information and compare, know the configuration information of peer node equipment.

The hdlc agreement is a High level data link control in the above-mentioned table 1, and the ppp agreement is a point-to-point protocol, all is positioned at link layer in network hierarchical structure.As long as wherein the figure place of the coding that need carry in keeping the position is not more than the total bit that keeps the position, when the figure place of coding less than the time when keeping the total bit of position, then only taking the part that keeps in the position is left and carries coding, four that four codings then only take among the Sa4-Sa8 in for example above-mentioned table 1 keep the position, and other unappropriated reservation are default value.
Embodiment two:
The Correspondent Node configuration information obtaining method that the embodiment of the invention two provides to obtain the example that is encoded in a plurality of Frames, is described the implementation procedure of the interface configuration information of obtaining peer node equipment in detail, and this method flow comprises the steps: as shown in Figure 5
Step S21: beginning.
Node device can begin by a timing break in service function entrance, and the application global variable, comprises coded query number of times cnt, initial code value, coding variable temp.
Step S22: judged whether to start the flow process of obtaining the peer node device configuration information.
Because node device can judge whether to need to start the flow process of obtaining the peer node device configuration information as the case may be, therefore, the application global variable has judged whether to start the flow process of obtaining the peer node device configuration information after making the break in service function begin to carry out.Also we can say whether be in the diagnostic mode that obtains the peer node device configuration information.
This step is an optional step, also can not carry out this step and gives tacit consent to and started diagnostic mode and direct execution in step S24.

If, execution in step S25; Otherwise, execution in step S26.
Step S25: from the Frame that receives, obtain the coding that carries, be recorded as initial code.
The coding that carries in the reservation position from chip register in the Frame of reading and recording.Because chip register is only preserved the Frame that receives from peer node equipment for the last time, therefore, need get off the encoded recording that carries in the Frame this moment, promptly writes among the initial code variable value of application, relatively uses in order to follow-up.
Execution in step S26 then.
Step S26: whether monitoring in real time receives alarm signal.
If, execution in step S27; Otherwise, execution in step S28.
This step is not limited to carry out after step S25, also can carry out before step S24 or step S25 or carry out simultaneously with step S24, step S25 or step S27.
Step S27: the flow process of ending to obtain the peer node device configuration information.
Optionally, this step can be carried out before step S24.
If receive alarm signal, then think the circuit instability, need close diagnostic mode, the flow process of peer node device configuration information is obtained in termination, at this moment, need empty coded query time number variable cnt, wait for that circuit restarts the flow process of obtaining the peer node device configuration information after stable again.
Step S28: from the Frame that receives, obtain the coding that carries.
The coding that carries in the reservation position from chip register in the Frame of reading and recording writes the coding that obtains in the coding variable temp variable of application.
Step S29: judge whether the coding that obtains is identical with initial code.
Whether the value of promptly judging temp variable and value variable is identical.
If return execution in step S30; Otherwise return execution in step S27.
Step S30: judge whether inquiry times reaches the frequency threshold value of setting.
Behind execution in step S29, cnt adds 1 with variable, judges then whether the cnt variable that adds after 1 reaches the frequency threshold value of setting, realizes judging whether inquiry times surpasses the set point number threshold value.
For example: for the false judgment that prevents that the circuit error code from causing, need continuous-query 5 times, if the value of the Sa4-Sa8 that inquires equates that all think that then the coding that receives is effective, be provided with the inquiry times threshold value this moment is 5, judges that then whether cnt is more than or equal to 5.
If, execution in step S32, otherwise execution in step S31.
Step S31: wait for receiving next Frame.
When inquiry times does not reach the frequency threshold value of setting, then can when receive next Frame, return and continue execution in step S24.
Step S32: determine the efficient coding that is encoded to of obtaining.
When inquiry times has reached the frequency threshold value of setting, determine the efficient coding that is encoded to that gets access to.
Step S33: inquire about the coding of local storage and the corresponding relation of configuration information, determine the configuration information of efficient coding correspondence, obtain the configuration information of peer node equipment interface.
The coding of local storage and the corresponding relation of configuration information can be shown in above-mentioned tables 1.
Step S34: judge whether peer node equipment has the configuration response demand.
According to the configuration information of the peer node equipment interface of determining, determine whether peer node equipment has configuration needs to this end node devices, for example whether requires this end node devices configuring external loop etc.
If, execution in step S35, otherwise execution in step S36.
Step S35: the configuration needs of response peer node equipment.
When whether peer node equipment has configuration needs to this end node devices, when for example requiring this end node devices configuring external loop, respond the configuration needs of peer node equipment, the configuring external loop.
Execution in step S36 then.
Step S36: the flow process that finishes to obtain the peer node device configuration information.
At the configuration information that gets access to peer node equipment, and when peer node equipment has configuration needs to this end node devices, should close diagnostic mode after the demand mutually, finish the flow process of obtaining the peer node device configuration information.
