Table 4

Step 804-step 805 is basic identical with step 604-step 605.

806, RE is after completing the HDLC link setup, the high layer software module of RE reads the link mode indication information L1 information, Slot ID and the first group of wireless standard indication information of a REC by the bottom software module from described interface module, and receives the port numbers of the first port of this L1 information.

807, RE software module on the middle and senior level is according to link mode indication information judgement CPRI link mode, if one way link pattern, according to one way link mode treatment in existing procedure, if Two-way Chain ring mode or double star chain pattern, carry out 808, in this step, judgment result is that Two-way Chain ring mode or double star chain pattern.

808, RE software module on the middle and senior level determines that the first port that receives this layer 1 information belongs to first group of wireless standard that a described REC supports.

Step 809-step 812 is basic identical with step 709-step 712.

It should be noted that: RE forwards mutually Slot ID(or Slot ID and the Port ID of the REC received at two ports), receive in other words Slot ID(or Slot ID and the Port ID of REC at a port) after at another port, send, every grade of RE processes like this.Under CPRI annular link condition, encircle Slot ID(or Slot ID and the Port ID of the REC of an end) can pass to the REC that encircles the other end, an end REC receives Slot ID(or Slot ID and the Port ID that other end REC sends).If this CPRI annular link disconnects, on chain, final stage RE can return to Slot ID(or Slot ID and the Port ID received), REC just can receive Slot ID(or Slot ID and the Port ID oneself sent like this), thereby learn that annular link disconnects.

Consult Fig. 9, describe as follows the concrete mode of the high layer software judgement CPRI link mode of a kind of REC:

The high layer software of step 901, REC obtains Slot ID and the Hop number received from the CPRI link.

Step 902, according to the Slot ID that receives, whether judge opposite end REC and own support phase wireless standard on the same group, if, think that the pattern of this CPRI link is Two-way Chain ring mode or double star chain pattern, carry out 903, otherwise, the pattern of determining this CPRI link is unidirectional chain ring mode, process ends.

Step 903, according to Hop number, judge on this CPRI link that several RE are arranged, if only have a RE on this CPRI link, the pattern of this CPRI link is the double star chain pattern, if on this CPRI link, a plurality of RE are arranged, the pattern of this CPRI link is the Two-way Chain ring mode.

Consult Figure 10, describe as follows the concrete mode of the high layer software judgement CPRI link mode of another kind of REC:

The high layer software of step 1001, REC obtains wireless standard indication information and the Hop number received from the CPRI link.

The CPRI link mode proposed for the embodiment of the present invention, what this REC received is the indication information of the wireless standard of opposite end REC support.

Indicated wireless of the wireless standard indication information that step 1002, judgement receive from the CPRI link indicates whether it is the wireless standard that this REC supports, if not, think that the pattern of this CPRI link is Two-way Chain ring mode or double star link mode, execution step 1003, if, the pattern of this CPRI link is unidirectional chain ring mode, process ends.

Step 1003, according to Hop number, judge on this CPRI link that several RE are arranged, if only have a RE on this CPRI link, the pattern of this CPRI link is the double star link mode, if on this CPRI link, a plurality of RE are arranged, the pattern of this CPRI link is the Two-way Chain ring mode.

It should be noted that, the Two-way Chain ring mode of above-mentioned Fig. 9 and Figure 10 also is applicable to only have on the CPRI link situation of a RE, in this case, as long as it is to adopt Two-way Chain ring mode or double star chain pattern that two REC preset when only having a RE, while on the CPRI link, only having a RE, general preferred employing double star chain pattern.

Consider that may there be the situation of frequent flash in the CPRI link, require REC handoff links pattern to have certain lag time, lag time can be decided to be a predetermined value, for example 3 minutes, if the CPRI link mode detected in other words becomes another kind of pattern, and the testing result of 3 minutes remains on another kind of pattern always, the CPRI link switching is another kind of pattern.

Perhaps, in the configuration Multi-Mode Base Station, give CPRI link configuration link mode (unidirectional chain ring mode, Two-way Chain ring mode or double star chain pattern).High layer software module on REC is used method as described above to detect the chain ring mode of actual CPRI link, and by the link mode of testing result and configuration relatively, report the abnormal alarm of indication link mode when inconsistent, to notify the inconsistent of current link mode and configuration.

Consult Figure 11, describe as follows under the Two-way Chain ring mode transport process of business datum:

RE receives from two ports the signal processing module that the business datum of respectively organizing wireless standard is given respectively corresponding wireless standard, signal processing module in the embodiment of the present invention can be DSP(Digital Signal Processing, Digital Signal Processing)/or ASIC(Application Specific Integrated Circuit, application-specific integrated circuit (ASIC)), also can adopt other signal processor, not affect realization of the present invention.The AxC that the high layer software module takies upper every group of carrier frequency corresponding to wireless standard of this RE or service area information configuration are to interface module, so interface module can be distinguished not the business datum of wireless standard on the same group.

When sending business datum, where the business datum that interface module sends as required organizes wireless standard if belonging to, and the business datum that this need to be sent mails to the RE port of corresponding wireless standard.

In this enforcement, first group of wireless standard supported in a REC(supposition, this first group of wireless standard comprises the GMS standard) send downlink service data to RE, interface module on the CPRI link in any one RE is according to AxC or service area information, be subordinated to the business datum of obtaining described RE in the downlink service data of the REC that the port (the first port) of this first group of wireless standard receives, send to the signal processing module of corresponding first group of wireless standard in described RE; Obtain in the signal processing module of this interface module corresponding second group of wireless standard from described RE and need to issue second group of wireless standard of the 2nd REC(supposition support, this second group of wireless standard comprises the UMTS standard) uplink business data, and close road (being combined) with the downlink service data of a REC, be sent to next RE by the second port, if the next stage of this RE is the 2nd REC, directly send the 2nd REC to.

That is to say, on a direction of CPRI link, be assumed to a REC from local terminal REC(), first carrying is the downlink service data of one group of wireless standard, then on this link, each RE obtains the downlink service data of oneself and inserts the uplink business data that another organizes wireless standard, when the information of final CPRI link bearer arrives other end REC, (the 2nd REC) can comprise: the downlink service data of the wireless standard that the uplink business data of the 2nd wireless standard that REC supports and a REC support, the 2nd REC obtains the uplink business data of own wireless standard, abandon the downlink service data of the wireless standard of the other side.

Wherein, the signal processing module of the signal processing module of corresponding first group of wireless standard and corresponding second group of wireless standard can be integrated in a signal processing module, does not affect realization of the present invention.

Wherein, REC obtains the mode of the uplink business data of own wireless standard and can be: the interface module of REC is according to the business datum of pre-configured AxC or service area acquisition of information oneself.

Under the Two-way Chain ring mode that the embodiment of the present invention is proposed, the service bandwidth of transmit traffic data is analyzed, from following formula, can find out: the Two-way Chain ring mode, in one direction, the uplink business data of the downlink service data of a corresponding REC and corresponding another REC is shared the service bandwidth of CPRI link.

Suppose, second group of wireless standard that first group of wireless standard that an above-mentioned REC supports only includes GSM standard, the 2nd REC support only includes the UMTS standard:

The bandwidth that the bandwidth that the service bandwidth that GSM takies to the UMTS direction=GSM downlink service data takies+the UMTS uplink business data takies

The bandwidth that the bandwidth that the service bandwidth that UMTS takies to the GSM direction=UMTS downlink service data takies+the GSM uplink business data takies.

Can find out, under the Two-way Chain ring mode, the bandwidth that two groups of wireless standards that two REC support are respectively used does not increase, and the business datum of two groups of wireless standards is shared the service bandwidth of CPRI link.

Consult Figure 12, describe as follows under the double star chain pattern transport process of business datum:

RE receives the business datum of one group of wireless standard from a port, give the signal processing module of corresponding wireless standard; Receive from another port the business datum that another organizes wireless standard, give corresponding another and organize the signal processing module of wireless standard.The AxC that the high layer software module takies upper every group of carrier frequency corresponding to wireless standard of this RE or service area information configuration are to interface module, so interface module can be distinguished not the business datum of wireless standard on the same group.

When sending business datum, where the business datum that interface module sends as required organizes wireless standard if belonging to, and the business datum that just this need to be sent mails to the RE port of corresponding wireless standard.

First group of wireless standard supported in the one REC(supposition, this first group of wireless standard comprises the GMS standard) send downlink service data to RE, the port (supposition is the first port) that interface module in RE is subordinated to this first group of wireless standard receives this downlink service data, sends to this to signal processing module that should first group of wireless standard; RE obtains uplink business data from the signal processing module of corresponding first group of wireless standard, by the first port, issues a REC.In like manner, second group of wireless standard supported in the 2nd REC(supposition, this second group of wireless standard comprises the UMTS standard) send downlink service data to RE, the port (the second port) that interface module in RE is subordinated to this second group of wireless standard receives this downlink service data, send to signal processing module that should second group of wireless standard, RE obtains uplink business data from the signal processing module to should second group of wireless standard, by the second port, issues the 2nd REC.

As can be seen from the above description, under double star chain mode, do not support the RE cascade, REC sends to the business datum of RE to finish at the RE place, does not need RE at another port repeat.RE sends to the business datum of REC need to distinguish port, certain is organized the business datum of wireless standard and can only send by the port of the wireless standard of correspondence, as can be seen from Figure 12, next business datum of organizing wireless standard of this mode can be monopolized the service bandwidth of a CPRI link.

Consult Figure 13, describe as follows under the Two-way Chain ring mode, control the transport process of data:

RE receives while controlling data, the advanced row cache of the control data that the interface module in RE is received two ports, and the control data of then two ports being received are ranked.Owing to controlling data with the HDLC address, two HDLC software modules can be set in RE, one of them is corresponding to a REC, another corresponding the 2nd REC, these two HDLC software modules bases HDLC address (the HDLC address of the wireless standard of correspondence that the RE for example described in abovementioned steps 605 records) separately, obtain out the control data of oneself from queue, and be transmitted to high layer software.

RE sends while controlling data, after interface module will be closed road (being combined) from the control data (control data and distribute to respectively the HDLC address of this RE with a REC and the 2nd REC) of two HDLC software modules, copied, copy and send from the first port and the second port respectively afterwards.

Specifically describe as follows: RE receives while controlling data, RE receives the control data from the first port and the second port, received control data are entered to queue, according to the HDLC address in the control data in described queue, two HDLC layer software modules of RE are obtained one's own control data from queue, and are transmitted to high layer software;
