Embodiment
For making purpose of the present invention, technical scheme and beneficial effect clearer,, the present invention is done detailed description further below in conjunction with embodiment and accompanying drawing.
In hop relay network, there are two kinds of scheduling modes: centralized scheduling mode and distributed scheduling mode.In the centralized scheduling mode, all link bandwidths are concentrated distribution by base station (BS); In the distributed scheduling mode, BS only distributes and the MS of its direct communication or the bandwidth of the link between the RS, and all the other channel widths are distributed by corresponding nontransparent RS.Described nontransparent RS is meant the RS that can independently generate downlink broadcast message, and corresponding transparent RS is for can not independently generating the RS of downlink broadcast message.
Under the distributed scheduling mode, BS can not fully in time obtain nontransparent RS to the scheduling situation of channel.If BS need to know that nontransparent RS to the distribution condition of channel resource, just need to inquire.Joint operation in below describing all refers to the joint operation in the hop relay network under the distributed scheduling mode.
Joint operation in the hop relay network can be divided into Three Estate equally: 0 grade, 1 grade and 2 grades.In joint operation, to judge that M S will carry out 1 grade or 2 cascades fashionable when serving BS broadcasts, just initiates the ranging parameters request.
After the ranging parameters request process finishes, distribute to the associating grade of MS according to the cooperation neighboring station, MS carries out concrete joint operation.At this moment, MS can carry out 0 grade, 1 grade or 2 grades of operations.
Because in 0 grade of joint operation, MS can only find range in the range finding configuration based on competition, the initiating ranging process that carries out when just entering network with MS is identical, belongs to prior art, repeats no more here.
1 grade of associating method that the embodiment of the invention provides comprises the steps: at least
After being received distance measurement request message by associating neighbours station, described distance measurement request message is sent to neighbours' base station BS from mobile station MS;
Described neighbours BS receives described distance measurement request message, sends ranging response message to described MS and described cooperation neighboring station.
If the cooperation neighboring station is nontransparent RS, then described transmission ranging response message is: neighbours BS sends ranging response message to the cooperation neighboring station;
Behind the described transmission ranging response message, further comprise: the cooperation neighboring station will be sent to MS from the ranging response message of neighbours BS;
Before described cooperation neighboring station received distance measurement request message, this method also comprised:
Carried out ranging parameters by associating neighbours station with neighbours BS and consult, described neighbours BS sends to serving BS broadcasts with the ranging parameters that consults, and the ranging parameters that meets the demands that described serving BS broadcasts will receive sends to described MS;
Described MS sends the CDMA ranging code and sends to described cooperation neighboring station according to the ranging parameters that receives;
Described cooperation neighboring station receives the CDMA code from described MS, judges distance measuring states, sends ranging response message to described MS; If the distance measuring states of carrying in this message is successfully, then described cooperation neighboring station is that described MS distributes the uplink bandwidth that sends distance measurement request;
When described MS receives described distance measuring states for successful ranging response message and described uplink bandwidth, send distance measurement request message to described cooperation neighboring station.
If the cooperation neighboring station is transparent RS, then described transmission ranging response message is: described neighbours BS sends ranging response message to described MS.
Fig. 1 is the flow chart of 1 grade of associating method in the junction network of first embodiment of the invention.The cooperation neighboring station is nontransparent RS in this flow process, and this flow process comprises the steps:
Step 101, neighbor base stations send the ranging parameters allocation request message to the cooperation neighboring station, in this message, comprise the associating grade of MS sign and request.
If the cooperation neighboring station is the base station, then consistent among the negotiations process of ranging parameters and the 16e, repeat no more here.
If the cooperation neighboring station is the RS under the serving BS, then directly sends ranging parameters to the cooperation neighboring station by serving BS and distribute request.
Step 102, quilt associating neighbours stand and respond the ranging parameters assignment response message, comprise the MS sign of allocation of parameters in this message and be the associating grade of this MS distribution, if the associating grade of distributing is 1 grade or 2 grades, also need to comprise the ranging parameters of distribution, comprise CDMA ranging code, gathering time, the biasing of ranging region launching opportunity.
Neighbours BS receives the ranging parameters assignment response message and passes to serving BS broadcasts, if the cooperation neighboring station is the RS under the serving BS broadcasts, then serving BS broadcasts directly and the cooperation neighboring station communicate, needn't pass through backbone network.Serving BS broadcasts judges that the ranging parameters that receives meets the demands, and then the ranging parameters negotiations process finishes, and serving BS broadcasts can generate the ranging parameters that consults the scanning response message, or is used for other operation.If serving BS broadcasts is judged the ranging parameters that receives and is not met the demands, then can require all neighbours BS again to consult to cooperation neighboring station's required parameter, also can consult to the neighbours BS required parameter at the place, part cooperation neighboring station that does not meet the demands.
The above-mentioned parameter negotiations process continues to carry out, and determines that up to serving BS broadcasts the ranging parameters that is assigned with meets the demands, or the parameter negotiation request reaches predefined number of times, or the time of parameter negotiation surpasses predefined time span.If does not again receive within a certain period of time the ranging parameters that neighbours BS sends and distribute request the cooperation neighboring station, think that then parametric distribution is successful, the content in the ranging parameters assignment response message of preparing to send according to the last time is carried out subsequent operation.
Step 103, serving BS broadcasts will be coordinated successful ranging parameters, comprise: CDMA sign indicating number, launching opportunity biasing, gathering time, be carried in the MOB SCN-RSP message and send to MS.
Step 104, MS is synchronous in frame and the cooperation neighboring station of assembling persond eixis, reads the UL-MAP message that sends on this frame, and extracts distance-finding method and ranging region.
Step 105, if be provided with the special ranging zone by associating neighbours station, MS will determine the launching opportunity of emission special ranging sign indicating number by comprehensively by the biasing of the launching opportunity biasing territory definition in the scanning response message of the special ranging territory of the UL-MAP message definition at associating neighbours station and serving BS broadcasts.
If the cooperation neighboring station just is provided with conventional ranging region, the ranging code that MS can distribute in the emission of this zone, thereby MS also can ignore it during joint coordination from the scanning response message that the service station receives the value in launching opportunity biasing territory.
If first frame of MS after the gathering time finishes can't obtain UL MAP message, MS will end just to attempt 1 joint process of carrying out with current cooperation neighboring station.After the termination, MS may carry out 0 grade of associating with this BS.
Step 106 is united neighbours and is stood erectly to connect RNG-RSP message is sent to MS.In this message, comprise distance measuring states, such as success, continue, cancellation or parameter is transferred in range finding and range finding again.
This moment, the cooperation neighboring station did not know which MS emission the CDMA code that receives is, the RNG-RSP message that therefore generates is broadcast; And CDMA code and launching opportunity that MS carries according to the RNG-RSP message that receives judge whether identical with CDMA code and the launching opportunity of self before emission, determine that if the same this message is transmitted to self, at this moment MS will carry out different operations according to the distance measuring states in the RNG-RSP message: if distance measuring states is continuation, then execution in step 107.
Step 107, MS adjusts CDMA according to ranging parameters and sends parameter, continues the CDMA ranging process, can to cause emission state be the CDMA code of successful RNG-RSP message until the cooperation neighboring station receives.After if the cooperation neighboring station receives the CDMA code, after judgement can emission state be successful RNG-RSP message, execution in step 108; For cancellation, then cancel ranging process if judge distance measuring states, this flow process finishes; For again range finding, then restart ranging process if judge distance measuring states, continue to carry out such as returning step 105.
Step 108, it is successful RNG-RSP message that the cooperation neighboring station sends distance measuring states to MS.
Step 109, the cooperation neighboring station distributes a uplink bandwidth by the UL-MAP broadcast to MS.
Step 108 is unfixing with the order of step 109, can according to circumstances be decided by system.
Step 110～step 111 unite neighbours station when receiving UL bandwidth and distance measuring states for successful RNG-RSP message, launches to have that the service station identifies and the RNG-REQ message of MS mac address information on the uplink bandwidth that is assigned with.
If there is the MS of a plurality of same services station identifications to send RNG-REQ message under the cooperation neighboring station, the cooperation neighboring station can also further merge these message becomes a message, is the serving BS broadcasts transmission RNG-REQ information of a plurality of MS to the cooperation neighboring station.
Step 112 after the serving BS broadcasts of cooperation neighboring station receives RNG-REQ message, is placed basic CID, the main management CID that distributes to MS in RNG-RSP message, can also place grade of service advance notice parameter, sends to the cooperation neighboring station.
If the cooperation neighboring station has carried out the joint operation with a plurality of MS, then the cooperation neighboring station need to be split as the response message that corresponds to each MS with the associating response message of a plurality of MS.
Step 113, the cooperation neighboring station sends to MS with the response message relevant with MS in the RNG-RSP message that receives.
Fig. 2 is the flow chart of 1 grade of associating method in the junction network of second embodiment of the invention.Be transparent RS by associating neighbours station in this flow process, if transparent RS is in current area, then do not need parameter-negotiation procedure, otherwise adopt ranging parameters negotiations process same as the prior art, coordinate the ranging parameters that provides to MS by serving BS broadcasts by backbone network and the neighbours BS that is requested to unite, unite the step that comprises for 1 grade that below provides after consulting through ranging parameters:

In this RNG_RSP message, comprise distance measuring states and ranging parameters.This moment, the cooperation neighboring station did not know which MS emission the CDMA code that receives is, the RNG_RSP message that therefore generates is broadcast; CDMA code and launching opportunity that MS carries according to the RNG-RSP message that receives judge whether identical with CDMA code and the launching opportunity of self before emission, know that if the same this message is transmitted to self, MS will carry out different operations according to the distance measuring states in the RNG-RSP message: if distance measuring states is continuation, then execution in step 205; If neighbours BS receives and adjudicates emission state behind the CDMA code is successfully, be successful RNG-RSP to MS emission distance measuring states, then execution in step 206.
Step 205, MS adjusts CDMA according to ranging parameters and sends parameter, continues the CDMA ranging process, can to cause emission state be the CDMA code of successful RNG-RSP message until the cooperation neighboring station receives.
Step 206, the cooperation neighboring station sends REL_RNG_REQ message to neighbours BS, to the measurement situation of neighbours BS report to the CDMA code, comprises needing Modulating Power, time, frequency and distance measuring states, such as success, continuation, cancellation or again range finding.
Step 207, after neighbours BS received the CDMA code, if judge that distance measuring states is successfully, then sending distance measuring states to MS was successful RNG-RSP message, execution in step 208; For cancellation, then cancel ranging process if judge distance measuring states, this flow process finishes; For again range finding, then restart ranging process if judge distance measuring states, continue to carry out such as returning step 202.
Step 208, neighbours BS distributes a uplink bandwidth by the UL-MAP broadcast to MS.
If neighbours BS judges that distance measuring states is successfully, then step 207 can according to circumstances be decided by system with the order of step 208.
Step 209 when MS receives UL bandwidth and distance measuring states for successful RNG-RSP message, identifies with the service station and the RNG-REQ message of MS mac address information to cooperation neighboring station's emission on the uplink bandwidth that distributes.
Step 210 is united the neighbours station RNG-REQ message that receives is sent to neighbours BS.
Step 211 after neighbours BS receives RNG-REQ message, is placed basic CID, the main management CID that distributes to MS in RNG-RSP message, can also place grade of service advance notice parameter, sends to MS.
