102, REC sends described descending CPRI frame by described master port, and with RE to carry out speed from port synchronous.
Particularly, in the step 102, described REC can at first send described descending CPRI frame with its flank speed of being supported, and receives uplink CP RI frame with the receiving velocity identical with described transmission rate.
In preset time T 1, if described REC receives the uplink CP RI frame identical with described transmission rate, and enter synchronous regime, then speed synchronous (L1 synchronization) is finished.If above-mentioned condition does not satisfy, then select another transmission rate, send described uplink CP RI frame once more, and receive descending CPRI frame with the receiving velocity of correspondence, finish synchronously until speed.Wherein, described preset time T 1 can be selected according to actual conditions, as 0.9～1.1s.
Wherein, the selection principle of speed can for, the flank speed of at first select supporting begins, and selects time high speed next time, successively changing down gradually.If minimum speed does not realize that then the highest speed is returned in redirect synchronously yet.
103, after speed was finished synchronously, REC was configured to the wavelength user mode control word in the described descending CPRI frame to use, and continues to issue the CPRI frame, enters protocol negotiation.
Particularly, described REC its master port RE corresponding with described CPRI passage finish from port speed synchronously after, first state information of the wavelength user mode control word in this CPRI frame carrying is replaced with second state information that the wavelength that is used to represent described CPRI passage correspondence has been used, with realization described wavelength user mode control word is configured to use, and send to described RE, so that whether described RE can judge its emission wavelength and receive wavelength wrong according to described wavelength control word and wavelength user mode control word.After this, described REC can further issue the CPRI frame, enters protocol negotiation and other follow-up flow processs.
In addition, in the CPRI frame that the master port of described REC further issues, can carry the highest CPRI version of its support, High-Level Data Link Control (HDLC) agreement, Ethernet speed and the corresponding up wavelength of the used downstream wavelength of this CPRI that it is supported, as: 1310nm.
Further, described wavelength machinery of consultation can also comprise:
104, receive the uplink CP RI frame that RE sends, and know the type whether corresponding RE the wavelength fault takes place and break down according to described uplink CP RI frame.
Described REC can receive up CPRI frame by its master port, and the information of obtaining the RE that the wavelength fault takes place according to the alarm territory of described uplink CP RI frame with and fault type information, the information of wherein said RE comprise send described uplink CP RI frame from the port numbers of port or the sequence number of described RE.
Particularly, the uplink CP RI frame that described RE sends can pre-definedly have an alarm territory, and described alarm territory can comprise two control words, and one of them control word is used to carry the information of described RE, such as sequence number or its port numbers from port of described RE; Another control word is used to carry the fault type information of RE, such as, " emission wavelength and reception wavelength are wrong ", " emission wavelength is wrong ", " it is wrong to receive wavelength " etc.Alarm territory control word can be selected any one the current untapped control word in the current reserve area of CPRI frame or the producer's self defined area.
In addition, should be appreciated that wavelength machinery of consultation that the foregoing description provides do not limit to and the master port that is applied on the REC; It also can be applicable on the port of the RE that has the master port functions of the equipments among a plurality of RE of system, that is, and and the port that has the master port functions of the equipments on some RE that described master port can also refer to link to each other with other RE.Certainly, according to the associated description of above embodiment, the person of ordinary skill in the field can recognize that when described method was applied in the port of the RE with master port functions of the equipments, each step need adjust accordingly according to using main body.
See also Fig. 3, the speed of carrying out principal and subordinate's port with REC and RE synchronously and the wavelength negotiation be example, from port side, the another kind of wavelength machinery of consultation that the embodiment of the invention provides can comprise:
201, described RE receives the descending CPRI frame that REC sends by it from port, and to carry out speed synchronous with the master port of described REC.
Particularly, described RE's receives descending CPRI frame from port with the highest receiving velocity of being supported.In 2 times, if receive the descending CPRI frame identical with present rate, and enter synchronous regime in preset time T, then speed is finished synchronously.If above-mentioned condition does not satisfy, then select another receiving velocity, descending once more reception CPRI frame.Wherein, described preset time T 2 can be selected according to actual conditions, as 3.9～4.1s.
With the speed syncsort of above-mentioned REC master port seemingly, from port carry out speed when synchronous the selection principle of speed be that the flank speed of at first selecting to support begins, and selects time high speed next time, successively changing down gradually.If minimum speed does not realize that then the highest speed is returned in redirect synchronously yet.
202, after speed is finished synchronously, described RE reads wavelength control word the descending CPRI frame that described master port issues by it from port, and from wherein obtaining the up wavelength information of corresponding CPRI passage.
204, whether the described RE up wavelength information of judging the CPRI passage that carries in the described wavelength control word is consistent from emission wavelength that port itself adopts with it, if unanimity then execution in step 205; If inconsistent then execution in step 208.
205, described RE reads wavelength user mode control word the CPRI frame that described master port issues by it from port, and judge whether wavelength user mode information that described wavelength user mode control word is carried represents that up wavelength/downstream wavelength used, if described wavelength is " not using ", then execution in step 206; Otherwise execution in step 207.
206, wavelength is consulted to finish, and described RE adopts above-mentioned wavelength to send follow-up CPRI frame.
Before this step, before promptly wavelength is consulted not finish, described RE from its transmitter of port shutdown, stop to send uplink CP RI frame.After consulting to finish from the port wavelength, Z.2.0, described RE can write the highest CPRI version that it is supported in the control word of the uplink CP RI frame that sends, Z.66.0 and Z.194.0 write HDLC and the Ethernet speed that it is supported respectively in control word, and send to the master port of described REC.
207, described RE alarms, and indication emission wavelength and reception wavelength are wrong.
If the up wavelength of common wireless interface passage is with identical from port self emission wavelength, and the wavelength of the wavelength user mode information representation correspondence that described wavelength user mode control word is carried is " using ", the emission wavelength that this RE uses then is described and receives wavelength all occupied.Therefore, in this step, described RE can produce warning information: " emission wavelength and reception wavelength are wrong ".Further, described RE can be when the user needs, and described RE can further alarm, and makes the user can know wrong type; If do not need to alarm to the user, described RE can directly report an error.
208, described RE reads the wavelength user mode control word in the CPRI frame that master port issues, judge whether described wavelength user mode control word institute loaded information represents that corresponding wavelength uses, if described wavelength is " use ", be execution in step 209 then; Otherwise execution in step 210.
209, described RE alarms, and the indication emission wavelength is wrong.
If the up wavelength information of described CPRI passage and described inconsistent from port self emission wavelength, and described wavelength user mode control word represents that corresponding wavelength is " not using ", illustrate that then described CPRI passage is unoccupied, but the emission wavelength that this RE uses is different with the up wavelength of this CPRI passage, so the emission wavelength that described RE uses is wrong.Therefore, in this step, described RE can produce warning information: " emission wavelength is wrong ".Further, described RE can be when the user needs, and described RE can further warn, and makes the user can know wrong type; If do not need to alarm to the user, described RE can directly report an error.
210, described RE alarms, and it is wrong that indication receives wavelength.
If the up wavelength information of described CPRI passage and described inconsistent from port self emission wavelength, and described wavelength user mode control word represents that corresponding wavelength is " using ", illustrate that then described CPRI passage is occupied, and the emission wavelength that described RE uses is different with the up wavelength of described CPRI passage, so the reception wavelength that described RE uses is wrong, it has received the information of other RE.Therefore, in this step, described RE can produce warning information: " it is wrong to receive wavelength ".Further, when the user needed, described RE can further alarm, and made the user can know wrong type, if do not need alarm, can directly report an error.
In addition, when above-mentioned various types of wavelength mistake occurring, alternatively, alarm to described REC further if desired, then enter step 211.
211, described RE alarms to the wireless device controls center.
Particularly, described RE goes up the CPRI frame of sending out can pre-definedly an alarm territory, and described alarm territory can comprise two control words, and one of them control word is used to carry the information of RE, such as sequence number or its port numbers from port of described RE; Another control word is used to carry the fault type information of RE, such as, " emission wavelength and reception wavelength are wrong ", " emission wavelength is wrong ", " it is wrong to receive wavelength " etc.Alarm territory control word can be selected any one the current untapped control word in the current reserve area of CPRI frame or the producer's self defined area.
For example, if number 75 and 139 reservation control word, the self-defined control word of producer of numbering 145 and 209 is not used, and then can use the reservation control word of numbering 75 and 139, wherein a pair of as alarm territory control word of numbering 145 and 209.When REC alarmed, described RE can be with port numbers or the sequence number that writes in one of them control word from port, Write fault type in another control word at needs.
In this step, described RE can be at self port numbers/sequence number and fault type of record in the control word of the alarm territory of the CPRI of its emission frame, and further sends to master port, reports to carry out fault to described REC, makes REC can know wrong type.Particularly, described RE can will write from the port numbers of port or the sequence number of described RE in one of them control word of control word of alarm territory, in another control word Write fault type emission wavelength and to receive wavelength wrong ", " emission wavelength is wrong " or " it is wrong to receive wavelength ", send to REC then.
Further, in the present embodiment, alternatively, the content that will alarm the control word of territory earlier after start from port empties.
In addition, one of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, described program can be stored in a kind of computer-readable recording medium, this program is when carrying out, comprise the steps: to receive the descending CPRI frame that the wireless device controls center sends, and to carry out speed synchronous with the master port at described wireless device controls center; After described speed is finished synchronously, obtain the up wavelength information and the wavelength user mode information of corresponding CPRI passage in wavelength control word from described descending CPRI frame and the wavelength user mode control word respectively; Whether wrongly judge from the emission wavelength and the reception wavelength of port according to described up wavelength information and wavelength user mode information.
Perhaps, carry out following steps: the up wavelength information of record CPRI passage in the wavelength control word of descending CPRI frame, and first state information is carried on wavelength user mode control word in the described descending CPRI frame, described first state information is used to represent that the wavelength of described CPRI passage correspondence is not used; Send described descending CPRI frame to wireless device, and with described wireless device to carry out speed from port synchronous; After speed is finished synchronously, first state information of carrying in the user mode control word with described descending CPRI frame replaces with second state information that the wavelength that is used to represent described CPRI passage correspondence has been used, and send to described wireless device, so that whether described wireless device is judged its emission wavelength and receives wavelength wrong according to described wavelength control word and wavelength user mode control word.
