Description

A kind of scan method, system and relay station in relay system

Technical field

The present invention relates to wireless communication technology, particularly a kind of scan method, system and relay station in relay system.

Background technology

Along with the continuous development of the communication technology, the requirement of communication system access rate is also being improved constantly, for satisfying the requirement of access rate, adopt the communication system of broadband wireless access (BWA) mode more and more to be subject to people's attention.Communication system based on IEEE 802.16e standard is exactly a kind of BWA communication system.

By the radio communication theory as can be known, transmission frequency is high more, and radio wave is fast more with range attenuation.The operating frequency of IEEE802.16e communication system is than higher, thereby the coverage of base station (BS) is very limited.For this reason, the 16j task groups of IEEE 802 working groups is being set up multi-hop wireless relay communications system standard, makes new system can support to communicate with BS by 1 or a plurality of relay station (RS) based on the MS of IEEE802.16e standard.

The multi-hop wireless relay communications system is made up of some sub-districts, and each sub-district comprises some radio communication multi-hop branch roads.Each bar radio communication multi-hop branch road can be expressed as BS＜-RS＜-RS＜-RS＜-RS＜-MS, wherein "＜-" each Radio Link of standing and communicating by letter and using of expression, the BS number is 1, the RS number can be 0,1 or a plurality of, the MS number can be 0 or 1, claim that BS, RS and MS are node, wherein, described BS is the 0th hop node, with BS be the i hop node at a distance of the node that i jumps, claim that the i-1 hop node is the father node of i hop node, the i+1 hop node is the child node of i hop node, and i is a natural number.BS does not have father node, and BS and RS can be father nodes, and RS can be a child node, and the final jump node does not have child node.The jumping sequence number is referred to as the downstream node of i hop node greater than the node of i.All nodes are all kept the sequence number of identical present frame at one time in the sub-district.

In communication system based on the 802.16e standard, BS broadcasts own sequence number at present frame in the control signaling of every frame, MS obtains the sequence number of BS at present frame by reading the control signaling, thereby the sequence number of the present frame that each node is kept at synchronization in the sub-district is identical.

Fig. 1 is the scanning flow chart of MS request in the prior art IEEE 802.16e standard.This flow process comprises the steps:

Step 101, when travelling carriage (MS) determines that certain one scan trigger flow condition satisfies, MS sends MOB_SCN-REQ message to serving BS broadcasts, in this message the neighbours of instruct MS request scanning stand tabulation, sweep spacing, insertion at interval, the sweep spacing occurrence number and for the scan type of each neighbour request of standing in the tabulation, and when certain neighbour requested scan type of standing be 1 grade or 2 grades when uniting scanning, also be that this neighbours BS indicates gathering time, CDMA sign indicating number and launching opportunity to setover.

Here, the sweep spacing occurrence number of indicating in the MOB_SCN-REQ message can be 1, also can be greater than 1.

Step 102, after serving BS broadcasts receives MOB_SCN-REQ message, to MS response MOB_SCN-RSP message, the request of MS is agreed or is refused in indication, if indication is agreed, then this message is also indicated the neighbours that the recommend MS scanning tabulation of standing, Report mode, start frame, be that frame number that MS begins to carry out scanning deducts the frame number that MS receives this message and subtracts 1 again, sweep spacing, insert at interval, the sweep spacing occurrence number, the scan type of standing and recommending for each neighbour in the tabulation, and be 1 grade or 2 grades and unite when scanning when certain neighbour recommended scan type of standing, also, these neighbours indicate the gathering time for standing, CDMA sign indicating number and launching opportunity biasing.

Here, the sweep spacing occurrence number of indicating in the MOB_SCN-RSP message can be 1, also can be greater than 1.

Step 103 after MS receives the MOB_SCN-RSP message of indication agreement, from the frame of this message indication, is carried out scanning in sweep spacing.MS scans one or more neighbours BS, after having discerned a neighbours BS, MS may attempt with the DL of this neighbours BS synchronously and measure the physical layer channel quality of this neighbours BS.If MS carries out associating scanning to this neighbours BS, then MS also can carry out joint operation to this neighbours BS.

Here, the sequence number of the frame of MOB_SCN-RSP message indication equals the start frame that frame number that MS receives this message adds this message indication and adds 1 again.

Step 104, the insertion of in MOB_SCN-RSP message, indicating interval, MS may send MOB_SCN-REP message to serving BS broadcasts, and reporting scanning result carries in this message: Report mode, neighbours BS tabulation reach the measurement result to each neighbours BS in the tabulation.

If the sweep spacing occurrence number of indicating among the MOB_SCN-RSP is greater than 1, promptly serving BS broadcasts is that MS has distributed one group of sweep spacing, and then MS carries out scanning at interval in follow up scan, and may send MOB_SCN-REP message to serving BS broadcasts at interval in follow-up insertion.Under special circumstances, MS can also send MOB_SCN-REP message to serving BS broadcasts at any time.

Fig. 2 is the scanning flow chart of serving BS broadcasts request in the prior art IEEE 802.16e standard.This flow process comprises the steps:

Step 201, when serving BS broadcasts determines that the trigger condition of instruct MS execution scanning satisfies, send MOB_SCN-RSP message to MS, the neighbours BS tabulation of MS scanning is recommended in indication in this message, Report mode, start frame, be that frame number that MS begins to carry out scanning deducts the frame number that MS receives this message and subtracts 1 again, sweep spacing, insert at interval, the sweep spacing occurrence number, the scan type of standing and recommending for each neighbour in the tabulation, and be 1 grade or 2 grades and unite when scanning when certain neighbour recommended scan type of standing, also be that this neighbours BS indicates gathering time, CDMA sign indicating number and launching opportunity biasing.

Step 202, after MS receives MOB_SCN-RSP message, frame from this message indication, carry out scanning in sweep spacing, scan one or more neighbours BS, after having discerned a neighbours BS, MS may attempt with the DL of this neighbours BS synchronously and measure the physical layer channel quality of this neighbours BS.If MS carries out associating scanning to this neighbours BS, then MS also can carry out joint operation to this neighbours BS.

Step 203, MS may send MOB_SCN-REP message to serving BS broadcasts in the insertion at interval of MOB_SCN-RSP message indication, indicate Report mode, neighbours BS tabulation to reach the measurement result to each neighbours BS in the tabulation in this message.

If the sweep spacing occurrence number of indicating in the MOB_SCN-RSP message is greater than 1, be that serving BS broadcasts is that MS has distributed one group of sweep spacing, then MS carries out scanning at interval and/or unites scanning in follow up scan, and can send MOB_SCN-REP message to serving BS broadcasts at interval in follow-up insertion.Under special circumstances, MS can also send MOB_SCN-REP message to serving BS broadcasts at any time.

The described MS of above-mentioned steps 103 and step 202 arrives shown in Figure 5 to idiographic flow such as Fig. 3 that neighbours BS carries out joint operation.

Fig. 3 is the flow chart of 0 grade of joint operation in the prior art IEEE 802.16e standard.This flow process comprises the steps:

Step 301, MS sets up with the DL of neighbours BS synchronous, reads the DL broadcast, and select an initial ranging sign indicating number (CDMA sign indicating number) randomly from initial ranging sign indicating number territory, selects a launching opportunity randomly in the initial ranging zone.

Step 302, the MS CDMA sign indicating number that emission is selected on the launching opportunity of selecting.

Step 303, the neighbours BS that is united scanning measures the CDMA sign indicating number that receives, and generates RNG-RSP message, comprise in this message: the distance measuring states of judgement, as success, continuation, cancellation or range finding again, ranging parameters is as time offset, transmitting power biasing, frequency offset.The neighbours BS that is united scanning this moment does not know which MS emission the CDMA sign indicating number that receives is, therefore the RNG-RSP that generates is a broadcast; And CDMA sign indicating number and launching opportunity that MS carries according to the RNG-RSP message that receives judge whether identical with the CDMA sign indicating number and the launching opportunity of self emission before, if identical then MS adjudicates this message and 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 304; Can to launch distance measuring states be successful RNG-RSP message if united neighbours BS judgement after receiving the CDMA sign indicating number of scanning, and then execution in step 305.If distance measuring states is then cancelled ranging process for cancellation; If distance measuring states is range finding again, the ranging process that then starts anew comprises and reselects CDMA sign indicating number etc.

Step 304, MS adjusts the CDMA sign indicating number according to ranging parameters and sends parameter, continues CDMA sign indicating number ranging process, receives up to the neighbours BS that is united scanning that can to cause emission state be the CDMA sign indicating number of successful RNG-RSP message.

Step 305, the neighbours BS that is united scanning specifically is a UL-MAP message by the DL broadcast, distributes a uplink bandwidth to MS.

Step 306, the neighbours BS that is united scanning is successful RNG-RSP message to MS emission distance measuring states.

Step 307, when MS received distance measuring states for successful RNG-RSP message, the neighbours BS transmission of uniting scanning to quilt on the uplink bandwidth that distributes had that serving BS broadcasts identifies and the RNG-REQ message of MS mac address information.

Step 308 after the neighbours BS that is united scanning receives RNG-REQ message, sends RNG-RSP message to MS, and this message comprises parameters such as basic CID, also may comprise grade of service advance notice parameter.

If the grade of service that is provided with in RNG-RSP message advance notice parameter is 2, MS will be in its local ident association list this BS of mark for to be united.MS keeps a timer, and the united state in the local association list lost efficacy behind this timer expiry, and the associating item is with deleted.

1 grade of joint operation has increased the combined parameters negotiation on the basis of 0 grade of joint operation mechanism, serving BS broadcasts is coordinated the combined parameters that provides to MS by backbone network and the neighbours BS that is requested associating scanning, comprises CDMA sign indicating number, launching opportunity biasing, ranging region, gathering time etc.

Unique initial CDMA sign indicating number and launching opportunity biasing in each neighbours BS that MS will carry out associating sign indicating number that to be quilt that MS the is pre-allocated in MS neighbours BS that unites scanning distribute for the MS that it is carried out initial ranging number, and send to serving BS broadcasts by backbone network.Neighbours BS may distribute identical sign indicating number or identical launching opportunity for different MS, but can sign indicating number all not identical with launching opportunity.Serving BS broadcasts will be coordinated neighbours BS, and the ranging region that each neighbours BS is distributed does not overlap or can be too not compact.The gathering time is a frame bias, is numerically equal to: recommended associating neighbours station sends the frame number of MOB_SCN-RSP for MS provides frame number-serving BS broadcasts of patent range transmitter meeting.

The combined parameters that the joint coordination stage obtains will offer MS by serving BS broadcasts emission scan response message.

Fig. 4 is 1 grade of joint operation flow chart being coordinated by serving BS broadcasts in the prior art IEEE 802.16e standard.Finish combined parameters in neighbours BS and serving BS broadcasts and coordinate, and after by the scanning response message combined parameters being offered MS by serving BS broadcasts, this flow process comprises the steps:

Step 401, MS unites the neighbours BS of scanning for it distributes the frame foundation of special ranging launching opportunity synchronous with the DL of neighbours BS at the quilt of gathering time indication, read the UL-MAP message that sends on this frame, and extract distance-finding method and ranging region.

Be provided with the special ranging zone if unite the neighbours BS of scanning, the launching opportunity of indicating in the special ranging territory of the UL-MAP message definition of the neighbours BS that MS will be by comprehensively being united scanning and the MOB_SCN-RS P message of serving BS broadcasts setovers to determine launching opportunity.

Just be provided with routine, non-special ranging zone if unite the neighbours BS of scanning, then this moment, MS can unite the CDMA sign indicating number of indicating in the neighbours BS emission MOB_SCN-RSP message of scanning to quilt on the conventional ranging region.

If first frame of MS after the gathering time finishes can't obtain UL_MAP message, MS will end just to attempt 1 grade of joint operation carrying out with the current neighbours BS that is united scanning.After the termination, MS may be united BS with this and be carried out 0 grade of joint operation.

Step 402～405 are identical to step 308 with the step 302 of 0 grade of joint operation shown in Figure 1, repeat no more here.

Fig. 5 is 2 grades of joint operation flow charts in the prior art IEEE 802.16e standard.

The step 501 of this flow process and 502 and step 401 and 402 identical repeats no more.2 grades of associatings are very close with 1 grade of associating, and difference is after the step 502 that MS need not to wait for the RNG-RSP message of neighbours BS.The RNG-RSP message content that each neighbours BS will have the correction of physical layer emission parameter, distance measuring states and grade of service indication sends to serving BS broadcasts by backbone network, as described in step 503 and step 504:

The RNG-RSP message content that step 503, each neighbours base station will have the correction of physical layer emission parameter, distance measuring states and grade of service indication sends to serving BS by backbone network.

Step 504, all RNG-RSP message contents that serving BS will receive are merged into single MOB_ASC-REP message and are transmitted to MS, comprise the MS ranging parameters that feed back to MS the neighbours base station when each neighbour is base stations united, distance measuring states, grade of service indication in this message.

In the multi-hop wireless relay communications system, MS may pass through the RS access network, and in this case, MS, RS or serving BS broadcasts all may be initiated scan request.Yet the scanning flow process in the prior art IEEE 802.16e standard can not satisfy this demand, does not promptly still exist in the prior art by MS, RS and serving BS broadcasts to carry out the flow process that information interaction is initiated scan request.In addition, the combined parameters coordinated manipulation in the IEEE 802.16e standard is also transferred to air interface from backbone network, needs the new combined parameters coordinated manipulation of design.

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.

The scan method in relay system that the embodiment of the invention provides comprises the steps: that at least this method comprises the steps:

Two kinds of RS types have been defined in the embodiment of the invention: high ability RS and low ability RS.

High ability RS can send the DL synchronizing information, can respond distance measurement request, and have scanning judgement ability.Low ability RS can not send the DL synchronizing information, can not respond distance measurement request, does not scan the judgement ability.

In trunk network, on same the radio communication multi-hop branch road high ability RS and low ability RS may be arranged simultaneously, the child node of high ability RS or BS can be low ability RS, other high ability RS or MS; But the child node of low ability RS can only be other low ability RS or MS.

What claim BS or high ability RS downstream can set up the synchronous RS of DL or MS for the controlled station of this BS or high ability RS by the DL synchronizing information that reads it, claims that this BS or high ability RS are the control station at controlled station, and wherein, high ability RS is called the control RS at controlled station.For control station and controlled station at a distance of greater than 1 situation of jumping, the station that the ranging code at controlled station is measured may not be the control station at this controlled station, but the low ability RS between control station and the controlled station, therefore in this case, controlled the standing in that all refer in the joint operation in the message ranging parameters hanged down the parameter that the range finding of ability RS place is obtained, rather than the controlled ranging parameters that stands in its control station place.

Wherein, the sweep object at controlled station is that neighbours stand, and the neighbours station can be BS or high ability RS.

BS has the scanning judgement ability to all RS or MS in its sub-district; High ability RS has limited scanning judgement ability, promptly can only adjudicate its controlled station and carry out scanning.And, high ability RS can for it the judgement of a certain controlled station be scanned that neighbours stand that set is BS for this station judgement be scanned the stand subclass of set of neighbours.

The embodiment of the invention provides in the multi-hop wireless relay communications system, by three kinds of scanning flow processs of serving BS broadcasts, control RS or the triggering of controlled station.

Fig. 6 is the flow chart by the scan method of serving BS broadcasts request of preferred embodiment of the present invention.This flow process comprises the steps:

Step 601, when serving BS broadcasts determines to satisfy scanning trigger flow condition, send relaying response (RL-RSP) message to control RS, the controlled station identifications of indication in this message, recommend the neighbours of the controlled station scanning tabulation of standing, Report mode, frame number, it is the frame number that controlled station begins to carry out scanning, sweep spacing, insert at interval, the sweep spacing occurrence number, the scan type of standing and recommending for each neighbour in the tabulation, and be 1 grade or 2 grades and unite when scanning when certain neighbour recommended scan type of standing, also, these neighbours indicate the gathering time for standing, CDMA sign indicating number and launching opportunity biasing.

Here, if having one or more other RS node between serving BS broadcasts and the control RS, then give control RS with the RL-RSP forwards by other RS node.

Step 602, after control RS receives RL-RSP message, send motion scan response (MOB_SCN-RSP) message to the controlled station corresponding with the controlled station identifications of indicating in this message, the neighbours of the controlled station scanning tabulation of standing is recommended in indication in this MOB_SCN-RSP message, Report mode, start frame, sweep spacing, insert at interval, the sweep spacing occurrence number, scan type for each neighbours BS recommendation in the tabulation, and unite when scanning when the recommended scan type of certain neighbours BS is 1 grade or 2 grades, also be that this neighbours BS indicates gathering time, CDMA sign indicating number and launching opportunity biasing.

Wherein, the information except that start frame, the corresponding information with RL-RSP message indication is identical respectively, and start frame equals the frame number of RL-RSP indication and deducts the frame number that controlled station receives MOB_SCN-RSP and subtract 1 again.

If have one or more other RS node between control RS and the controlled station, then MOB_SCN-RSP be transmitted to controlled station by other RS node.

Step 603 when controlled station receives MOB_SCN-RSP message, from the frame of this message indication, is carried out in sweep spacing and non-ly to be united scanning or to unite scanning.

Here, unite the scanning process that scanning refers to comprise joint operation, the non-associating scanned the scanning process that refers to not comprise joint operation.

Step 604, controlled station can be in the insertion at interval of MOB_SCN-RSP message indication, send motion scan report (MOB_SCN-REP) message to control RS, the measurement result to the physical layer channel quality of each neighbours BS correspondence during order report pattern, neighbours stand and tabulate and tabulate.

If have one or more other RS node between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

Step 605, when control RS receives MOB_SCN-REP message, send relaying report (RL-REP) message to serving BS broadcasts, stand each neighbour in tabulation and the tabulation of indication controlled station identifications, Report mode, neighbours each neighbour corresponding measurement result to the physical layer channel quality of standing of standing in tabulation and the tabulation in this message, and Report mode again, neighbours stand that the corresponding information with the MOB_SCN-REP indication is identical respectively for the measurement result of corresponding physical layer channel quality.

If have one or more other RS node between control RS and the serving BS broadcasts, then give serving BS broadcasts with the RL-REP forwards by other RS node.

If the sweep spacing occurrence number of indicating among the MOB_SCN-RSP is greater than 1, be that serving BS broadcasts is that one group of sweep spacing has been distributed at controlled station, the then controlled follow up scan that stands in is carried out scanning at interval, and can send MOB_SCN-REP message to control RS at interval in follow-up insertion.In this case, if having one or more other RS node between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

Under special circumstances, controlled station can also be at any time sends MOB_SCN-REP to control RS, if this moment controlled station and control RS between have one or more other RS node, then give control RS with the MOB_SCN-REP forwards by other RS node.

Fig. 7 is the flow chart by the scan method of controlling the RS request of preferred embodiment of the present invention.This flow process comprises the steps:

Step 701, when control RS determines to satisfy scanning trigger flow condition, send relay request (RL-REQ) message to serving BS broadcasts, the controlled station identifications of indication, frame number in this message, promptly controlled station begins to carry out frame number, sweep spacing, insertion interval, the sweep spacing occurrence number of scanning.

If have one or more other RS nodes between control RS and the serving BS broadcasts, then give serving BS broadcasts with the RL-REQ forwards by other RS node.

After step 702, serving BS broadcasts receive RL-REQ message, to control RS response relaying response (RL-RSP) message, controlled station identifications of indication and indication information in this RL-RSP message.

Described indication information is: the information of indicating in the RL-REQ message that serving BS broadcasts is agreed to receive; Or serving BS broadcasts need be revised the information of indicating in the RL-REQ message that receives; Or the information of indicating in the RL-REQ message rejected of serving BS broadcasts.

If have one or more other RS nodes between serving BS broadcasts and the control RS, then give control RS with the RL-RSP forwards by other RS node.

Step 703, after control RS sends RL-REQ, at certain time intervals in,

If control RS receives the RL-RSP message that indication is agreed, then send MOB_SCN-RSP message to controlled station, the neighbours of the controlled station scanning tabulation of standing is recommended in indication, Report mode, start frame, it is the frame number-1 that frame number-MS of indicating in the RL-REQ message receives MOB_SCN-RSP message, sweep spacing, insert at interval, the sweep spacing occurrence number, the scan type of standing and recommending for each neighbour in the tabulation, and be 1 grade or 2 grades and unite when scanning when certain neighbour recommended scan type of standing, also, these neighbours indicate the gathering time for standing, CDMA sign indicating number and launching opportunity biasing.

If have one or more other RS nodes between control RS and the controlled station, then MOB_SCN-RSP be transmitted to controlled station by other RS node;

If control RS receives the RL-RSP message that indication is revised, then control RS and judge whether to satisfy scanning trigger flow condition, if satisfy, the RL-REQ message that sends before then upgrading, promptly revise frame number, sweep spacing, insertion at interval, and sweep spacing occurrence number information in one or more, and send RL-REQ message after upgrading to serving BS broadcasts.At this moment, serving BS broadcasts receive after the RL-REQ message after the renewal processing mode with receive the described RL-REQ message of step 703 after processing mode identical.

If have one or more other RS nodes between control RS and the serving BS broadcasts, then RL-REQ be transmitted to serving BS broadcasts by other RS node;

If control RS receives the RL-RSP message of indication refusal, this request of then controlling RS finishes;

If control RS does not receive RL-RSP message, then can retransmit RL-REQ message to serving BS broadcasts, there are one or more other RS nodes if control between RS and the serving BS broadcasts this moment, then give serving BS broadcasts with the RL-REQ forwards by other RS node.

Step 704 after controlled station receives MOB_SCN-RSP message, from the frame of this message indication, is carried out in sweep spacing and non-ly to be united scanning or to unite scanning.

Step 705, the insertion of in MOB_SCN-RSP message, indicating at interval, controlled station can send MOB_SCN-REP message to control RS, order report pattern, neighbours each neighbour corresponding measurement result to the physical layer channel quality of standing of standing in tabulation and the tabulation.

At this moment, if having one or more other RS nodes between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

If the sweep spacing occurrence number of indicating in the MOB_SCN-RSP message is greater than 1, be that controlled station has been assigned with one group of sweep spacing, the then controlled follow up scan that stands in is carried out scanning at interval, and can send MOB_SCN-REP message to control RS in follow-up insertion at interval.Under special circumstances, controlled station can also send MOB_SCN-REP message to control RS at any time.If have one or more other RS nodes between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

Fig. 8 is the flow chart by the scan method of controlled station request of preferred embodiment of the present invention.This flow process comprises the steps:

Step 801, when scanning trigger flow condition is determined to satisfy in controlled station, RS sends MOB_SCN-REQ message to control, in this message the neighbours of the controlled station of indication request scanning stand tabulation, sweep spacing, insertion interval, sweep spacing occurrence number, be the stand scan type of recommendation of each neighbour in the tabulation.

If have one or more other RS nodes between controlled station and the control RS, then give control RS with the MOB_SCN-REQ forwards by other RS node.

Step 802, control be after RS receives MOB_SCN-REQ message, and judgement is stood tabulation whether all in the decision range of controlling RS by the neighbours of controlled station request scanning.

Step 803, if court verdict is for being, then control RS and send RL-REQ message to serving BS broadcasts, indicate court verdict, controlled station identifications, frame number in this RL-REQ message, promptly controlled station begins to carry out frame number, sweep spacing, insertion interval and the sweep spacing occurrence number of scanning;

If court verdict is for denying, promptly one or more neighbours station of being stood in tabulating by the neighbours of controlled station request scanning has exceeded the decision range of controlling RS, then control RS and send RL-REQ message to serving BS broadcasts, indicate in this RL-REQ message the neighbours of the controlled station request scanning of court verdict, controlled station identifications and the indication of MOB_SCN-REQ message stand tabulation, sweep spacing, insertion interval, sweep spacing occurrence number, and be the stand scan type of recommendation of each neighbour in the tabulation.

Step 804, after serving BS broadcasts receives RL-REQ message, if the court verdict of RL-REQ message indication is for being, then serving BS broadcasts sends RL-RSP message to control RS, indicate court verdict, controlled station identifications, indication information in this RL-RSP message, this indication information can be for agreeing, revise or the refusal indication information;

If the court verdict of RL-REQ message indication is for denying, then serving BS broadcasts sends RL-RSP message to control RS, indication court verdict, controlled station identifications, recommend the neighbours of controlled station scanning stand tabulation, Report mode, frame number, be the controlled station frame number that begins to carry out scanning, sweep spacing, insertion interval, sweep spacing occurrence number, for each neighbour in the tabulation stand the scan type of recommending, and when certain neighbour recommended scan type of standing be 1 grade or 2 grades when uniting scanning, also indicate gathering time, CDMA sign indicating number and launching opportunity to setover for these neighbours stand.

Step 805, after control RS sends RL-REQ message, at certain time intervals in,

If control RS receives court verdict for being, and the RL-RSP message of indication information for agreeing, then control RS and send MOB_SCN-RSP message to controlled station, the neighbours of the controlled station scanning tabulation of standing is recommended in indication, Report mode, start frame, it is the frame number-1 that the frame number-MS of RL-REQ indication receives MOB_SCN-RSP, sweep spacing, insert at interval, the sweep spacing occurrence number, the scan type of standing and recommending for each neighbour in the tabulation, and be 1 grade or 2 grades and unite when scanning when certain neighbour recommended scan type of standing, also, these neighbours indicate the gathering time for standing, CDMA sign indicating number and launching opportunity biasing.If have one or more other RS nodes between control RS and the controlled station, then give controlled station with the MOB_SCN-RSP forwards by other RS node;

If control RS receives court verdict for being, and the RL-RSP message of indication information for revising, then control RS and judge whether to satisfy scanning trigger flow condition, when judgement is satisfied, the RL-REQ message that sends before then upgrading, promptly revise frame number, sweep spacing, insertion at interval, and sweep spacing occurrence number information in one or more, and send RL-REQ message after upgrading to serving BS broadcasts.At this moment, serving BS broadcasts receive after the RL-REQ message after the renewal processing mode with receive the described RL-REQ message of step 703 after processing mode identical.

If have one or more other RS nodes between control RS and the serving BS broadcasts, then give serving BS broadcasts with the RL-REQ forwards by other RS node;

If control RS receives court verdict for being, and indication information is the RL-RSP message of refusal, then controls this request end of RS;

If receiving court verdict, control RS is RL-RSP message not, then control RS and send MOB_SCN-RSP message to the controlled station corresponding with the controlled station identifications of RL-RSP message indication, indication recommend the neighbours of controlled station scanning stand tabulation, Report mode, start frame, sweep spacing, insertion interval, sweep spacing occurrence number, for each neighbour in the tabulation stand the scan type of recommending, and when certain neighbour recommended scan type of standing be 1 grade or 2 grades when uniting scanning, also indicate gathering time, CDMA sign indicating number and launching opportunity to setover for these neighbours stand.Wherein, the information except that start frame, identical with the corresponding information that comprises among the RL-RSP respectively, and start frame equals the frame number of RL-RSP indication and subtracts the frame number that controlled station receives MOB_SCN-RSP and subtract 1 again.If have one or more other RS nodes between control RS and the controlled station, then give controlled station with the MOB_SCN-RSP forwards by other RS node.

Step 806, if after controlled station sends MOB_SCN-REQ message, at certain time intervals in, receive MOB_SCN-RSP message, then controlled station is from the frame of this message indication, carries out in sweep spacing and non-ly unites scanning or unite scanning.

Step 807, in the insertion that controlled station can be indicated in MOB_SCN-RSP message at interval, RS sends MOB_SCN-REP message to control, order report pattern, neighbours each neighbour corresponding measurement result to the physical layer channel quality of standing of standing in tabulation and the tabulation.

If have one or more other RS nodes between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

Step 808, if the court verdict of control RS is for denying, when then controlling RS and receiving MOB_SCN-REP message, send RL-REP message to serving BS broadcasts, indicate controlled station identifications, Report mode, neighbours each neighbour corresponding measurement result of standing of standing in tabulation and the tabulation to the physical layer channel quality, and these information the corresponding information with the indication of MOB_SCN-REP message is identical respectively.

If the sweep spacing occurrence number of indicating in the MOB_SCN-RSP message that the described controlled station of step 806 receives is greater than 1, be that controlled station has been assigned with one group of sweep spacing, the then controlled follow up scan that stands in is carried out scanning at interval, and can send MOB_SCN-REP message to control RS at interval in follow-up insertion.Under special circumstances, controlled station can also send MOB_SCN-REP message to control RS at any time.If have one or more other RS nodes between controlled station and the control RS, then give control RS with the MOB_SCN-REP forwards by other RS node.

For the step 804 among the step 702 among Fig. 7 and Fig. 8, when serving BS broadcasts when control RS sends indication information for the RL-RSP message agreed, can further include step: be increased in the sweep spacing occurrence number of indicating in the RL-REQ message.At this moment, serving BS broadcasts after also indication is upgraded in RL-RSP message the sweep spacing occurrence number or the added value of sweep spacing occurrence number, and control is after RS receives this RL-RSP message, the sweep spacing occurrence number after indication is upgraded in sending to the MOB_SCN-RSP message at controlled station.

In the step described in the step 805 of the step 703 of Fig. 7 and Fig. 8: control RS receives court verdict for being, and the RL-RSP message of indication information for revising, then control RS and judge whether to satisfy scanning trigger flow condition, when judgement is satisfied, control RS judges whether to satisfy scanning trigger flow condition, and when determining to satisfy, the RL-REQ message that sends before upgrading, promptly revise frame number, sweep spacing, insertion at interval, and sweep spacing occurrence number information in one or more, and send RL-REQ message after upgrading to serving BS broadcasts.At this moment, serving BS broadcasts receive after the RL-REQ message after the renewal processing mode with receive the described RL-REQ message of step 703 after processing mode identical.

This step can replace with: send new RL-REQ message to serving BS broadcasts, but include only the information that is modified in the out of Memory of controlled station identifications and the indication of former RL-REQ message in the message.In this case, serving BS broadcasts is stored the information of former RL-REQ message indication, and according to the information of the former RL-REQ message indication that receives the storage of new RL-REQ information updating, and adjudicate indication information (i.e. agreement/modification/refusal) again according to the information after upgrading.

In the step 804 of the step 702 of the step 601 of Fig. 6 or Fig. 7 or Fig. 8, when serving BS broadcasts sends the RL-RSP message of indication frame number to control RS, if serving BS broadcasts known control RS receives RL-RSP message and serving BS broadcasts sends the frame number that RL-RSP message is separated by, then described frame number can replace with start frame, and this moment, start frame had two kinds of implications:

1) controlled station frame number-serving BS broadcasts of beginning to carry out scanning sends the frame number-1 of this RL-RSP message.At this moment, control RS can receive the frame number that RL-RSP message and serving BS broadcasts transmission RL-RSP message is separated by according to start frame, the control RS of RL-RSP message indication obtain the frame number that controlled station begins to carry out scanning, thereby obtains the start frame of indicating in the MOB_SCN-RSP message.

2) controlled station frame number-control RS of beginning to carry out scanning receives the frame number-1 of this RL-RSP.At this moment, control RS can obtain the frame number that controlled station begins to carry out scanning according to the start frame of RL-RSP message indication, the frame number that control RS receives this RL-RSP message, thereby obtains the start frame of indicating in the MOB_SCN-RSP message.

In the step 803 of the step 701 of Fig. 7 or Fig. 8, when control RS sends the RL-REQ message of indication frame number, if control RS known service BS receives RL-REQ message and sends the frame number that RL-REQ message is separated by with control RS, then frame number can replace with start frame, and this moment, start frame had two kinds of implications:

1) controlled station frame number-control RS of beginning to carry out scanning sends the frame number-1 of this RL-REQ message.At this moment, serving BS broadcasts can obtain the frame number that controlled station begins to carry out scanning with the frame number that control RS transmission RL-REQ message is separated by according to start frame, the serving BS broadcasts reception RL-REQ message of RL-REQ message indication.

2) controlled station frame number-serving BS broadcasts of beginning to carry out scanning receives the frame number-1 of this RL-REQ message.At this moment, serving BS broadcasts can RL-REQ message the start frame, the frame number that serving BS broadcasts receives RL-REQ message of indication obtain the frame number that controlled station begins to carry out scanning.

In the step 804 of the step 702 of the step 601 of Fig. 6 or Fig. 7 or Fig. 8, when serving BS broadcasts sends the message of the RL-RSP that indicates frame number, if the known controlled station of serving BS broadcasts receives MOB_SCN-RSP message and serving BS broadcasts sends the frame number that RL-RSP message is separated by, then the frame number of indicating in the message of RL-RSP can replace with start frame, at this moment, frame number is: frame number-controlled station that controlled station begins to carry out scanning receives the frame number-1 of MOB_SCN-RSP message.Correspondingly, in the step 805 among the step 602 among Fig. 6 and Fig. 8, control is after RS receives RL-RSP message, with the start frame of the RL-RSP message indication start frame as the indication of MOB_SCN-RSP message.

The embodiment of the invention is that controlled station has provided the flow process of carrying out joint operation in sweep spacing with MS.In junction network, with identical in the 16e network, MS can only find range in the range finding configuration based on competition.Whether according to having low ability RS to divide between neighbours station of being united scanning and the MS, 0 grade of associating step is incomplete same.

Fig. 9 and Figure 10 are the flow chart of two kinds of situations of 0 grade of joint operation in relay system of the embodiment of the invention.The neighbours station of being united scanning in the embodiment shown in fig. 9 is BS, and the neighbours that united scanning stand and MS between low ability RS is arranged.This flow process comprises the steps:

Step 901, MS be scanned neighbours BS and carry out downlink synchronization, read the downlink broadcast message of standing and sending, from the initial CDMA sign indicating number of neighbours territory, select a CDMA sign indicating number randomly, and in the initial ranging zone, select a launching opportunity at random from the neighbours that united scanning.

Step 902, MS unites the CDMA sign indicating number of the neighbours BS emission selection of scanning to quilt in the initial ranging launching opportunity of selecting.

Step 903 when low ability RS receives the CDMA sign indicating number, is measured the CDMA that receives, and generates CDMA sign indicating number report message, informs the neighbours BS that is united scanning, i.e. the control station of the low ability RS of neighbours, the ranging parameters that the CDMA sign indicating number is measured.

Because of this low ability RS has a plurality ofly, these low ability RS and the neighbours BS that is united scanning may receive the CDMA sign indicating number of MS, need be selected one from these CDMA sign indicating number recipients so unite the neighbours BS of scanning, unite the object of range finding as MS.

Step 904, the neighbours BS that is united scanning generates ranging response message (RNG-RSP), and sends to this quilt and unite the MS that the neighbours BS of scanning selects and unite the range finding object, and by this range finding object with the RNG-RSP forwards to MS.In this message, comprise distance measuring states, as success, continuation, cancellation or range finding again, and ranging parameters.

The neighbours BS that is united scanning this moment does not know which MS emission the CDMA sign indicating number that receives is, therefore the RNG-RSP message that generates is broadcast; And CDMA sign indicating number and launching opportunity that MS carries according to the RNG-RSP message that receives judge whether identical with the CDMA sign indicating number and the launching opportunity of self emission before, if identical then definite this message is transmitted to self, at this moment MS will carry out different operations according to the distance measuring states among the RNG-RSP:

If distance measuring states is continuation, then execution in step 905.If distance measuring states is then cancelled ranging process for cancellation; If distance measuring states is range finding again, ranging process then starts anew.

Step 905～step 906, MS adjusts CDMA according to ranging parameters and sends parameter, continues the CDMA ranging process, receives up to the neighbours BS that is united scanning that can to cause emission state be the CDMA sign indicating number of successful RNG-RSP message.If united the neighbours BS of scanning receive behind the CDMA sign indicating number judgement can emission state for after the successful RNG-RSP message, execution in step 907.

Step 907, the neighbours BS that is united scanning is successful RNG-RSP message to low ability RS transmission distance measuring states, is transmitted to MS after the low ability RS of neighbours receives this message.

Step 908, the neighbours BS that is united scanning distributes a uplink bandwidth by downlink broadcasting message to MS, is successful RNG-RSP message to MS emission distance measuring states then;

Step 909, when receiving UL bandwidth and distance measuring states for successful RNG-RSP message, MS launches on the uplink bandwidth that is assigned with and has that the service station identifies and the RNG-REQ message of MS mac address information.This message is passed through the neighbours BS that is united scanning by the object of finding range.

Step 910 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.

If the grade of service that is provided with in RNG-RSP message advance notice parameter is 2, MS will be in its local ident association list this associating scanned objects of mark for to be united.MS keeps a timer, and the united state in the local association list lost efficacy behind this timer expiry and it is deleted to unite.

Among the embodiment shown in Figure 10, the neighbours station of being united scanning is high ability RS, and is united between the neighbours station of scanning and the MS and hang down ability RS.This flow process comprises the steps:

Step 1001, MS carries out downlink synchronization with the neighbours station of being united scanning, read the downlink broadcasting message of standing and sending, from the initial CDMA sign indicating number of neighbours territory, select a CDMA sign indicating number randomly, and in the initial ranging zone, select a launching opportunity at random from the neighbours that united scanning.

Step 1002, the neighbours that MS unites scanning in the initial ranging launching opportunity of selecting to quilt stand and send the CDMA sign indicating number of selection.

Step 1003, the neighbours that united scanning stand erectly to connect RNG-RSP message are sent to MS.In this message, comprise distance measuring states, as success, continue, cancellation or parameter is transferred in range finding and range finding again.

Be scanned the high ability RS of neighbours this moment and do not know which MS emission the CDMA sign indicating number that receives is, therefore the RNG-RSP message that generates is broadcast; And CDMA sign indicating number and launching opportunity that MS carries according to the RNG-RSP message that receives judge whether identical with the CDMA sign indicating number and the launching opportunity of self emission before, if identical then definite 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 1004.

Step 1004, MS adjusts CDMA according to ranging parameters and sends parameter, continues the CDMA ranging process, receives up to being scanned the high ability RS of neighbours that can to cause emission state be the CDMA sign indicating number of successful RNG-RSP message.If after being scanned the high ability RS of neighbours and receiving the CDMA sign indicating number, after judgement can emission state be successful RNG-RSP message, execution in step 1005.

Step 1005, the neighbours station of being united scanning is successful RNG-RSP message to MS transmission distance measuring states.

Step 1006 is united the neighbours station of scanning and is distributed a uplink bandwidth by the UL-MAP broadcast to MS, is successful RNG-RSP message to MS emission distance measuring states then;

When step 1007～step 1008, the neighbours station of being united scanning received UL bandwidth and distance measuring states for successful RNG-RSP message, emission had that the service station identifies and the RNG-REQ message of MS mac address information on the uplink bandwidth that is assigned with.

Sent RNG-REQ message if unite stand the down MS of a plurality of same services station identifications of the neighbours of scanning, being scanned the high ability RS of neighbours can also further become a message with these message merging, unites the serving BS broadcasts solicited message at the neighbours station of scanning to quilt for a plurality of MS.

Step 1009 after the serving BS broadcasts of being united the neighbours station of scanning 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 neighbours station of being united scanning.

Carried out joint operation with a plurality of MS if unite the high ability RS of the neighbours of scanning, the high ability RS of neighbours that is then united scanning need be split as the response message that corresponds to each MS with the associating response message of a plurality of MS.

If the grade of service that is provided with in RNG-RSP message advance notice parameter is 2, MS will be in its local ident association list this associating object of mark for to be united.MS keeps a timer, and the united state in the local association list lost efficacy behind this timer expiry and it is deleted to unite.

Step 1010, the high ability RS of neighbours sends to MS with the response message relevant with MS in the RNG-RSP message that receives.

1 grade of associating is identical with 1 grade of associating purpose in the 16e network in the junction network.1 cascade is combined in and has increased a combined parameters on the basis of 0 grade of associating mechanism and consult, and serving BS broadcasts coordinates to be united the neighbours station of scanning, to provide combined parameters to MS.

Combined parameters coordinate to be meant serving BS broadcasts with the neighbours station of being united scanning between to hold consultation with regard to combined parameters, CDMA sign indicating number, the launching opportunity that negotiation MS will use in the associating stage setovered, gathering incident and ranging region.

Figure 11 is the flow chart of the 1 grade joint operation of the embodiment of the invention in relay system, is scanned the neighbours low ability RS that stands down in this embodiment, and is coordinated to be united the neighbours station of scanning by serving BS broadcasts.

Step 1101, be the high ability RS of neighbours if unite the neighbours station of scanning, then need stand to the neighbours that quilt is united scanning and send the ranging parameters allocation request message in the neighbours base station, in this message, comprise the parameter of MS sign, needs request, comprise biasing in CDMA ranging code, gathering time, the distance measurement zone.

Ask ranging region if desired, then also need to comprise the ranging region of serving BS broadcasts suggestion in the ranging parameters allocation request message.

Be the base station if unite the neighbours station of scanning, then consistent among process and the 16e, repeat no more here.

Step 1102, the neighbours that united scanning stand and respond the ranging parameters assignment response message, the MS sign that comprises allocation of parameters in this message, the parameter of asking in the ranging parameters allocation request message comprises CDMA ranging code, gathering time, the biasing of ranging region launching opportunity.

If in the ranging parameters allocation request message, asked ranging region, then in response message, only need inform the distance measurement zone of whether having accepted the BS suggestion.If do not accept, the stand ranging region of own selection of neighbours that notification service BS whether is united scanning can be continued to inform in the neighbours station of being united scanning.If do not inform, think that then the neighbours station of being united scanning can not unite range finding for this and distribute the special ranging zone, if inform, inform that then serving BS broadcasts united the stand ranging region of own selection of the neighbours of scanning.

Neighbours BS receives the ranging parameters assignment response message and passes to serving BS broadcasts by backbone network.If serving BS broadcasts is disagreed with this parameter, then need once more required parameter to consult.Stood in and do not receive request message in the certain hour once more if unite the neighbours of scanning, think that then parameter is allocated successfully, the content in the ranging parameters assignment response message of preparing to send according to the last time is carried out subsequent operation.

CDMA sign indicating number in the ranging parameters that step 1103, serving BS broadcasts will obtain in the time of will coordinating successfully, launching opportunity biasing, gathering time are included in the MOB_SCN-RSP message and send to MS.Wherein, the gathering time equals the frame number that MS reads the UL-MAP at the neighbours station of being united scanning and subtracts the frame number that MS receives MOB_SCN-RSP.

When the control station of MS is high ability RS, the combined parameters at the neighbours station of scanning is united in the coordination of high ability RS request serving BS broadcasts, after serving BS broadcasts is coordinated successfully, CDMA sign indicating number in the combined parameters after coordinating, launching opportunity biasing, gathering time are sent to high ability RS, by high ability RS described three parameters are included in the MOB_SCN-RSP message again and send to MS.

Step 1104, MS will stand synchronously with the neighbours that united scanning at the frame of gathering time indication, read the UL-MAP message that sends on this frame, and extract distance-finding method and ranging region.

Step 1105, be provided with the special ranging zone if unite the neighbours station of scanning, the launching opportunity of emission special ranging sign indicating number is determined in the biasing of the launching opportunity biasing territory definition in the special ranging territory of the UL-MAP message definition that MS will stand by the neighbours that comprehensively united scanning and the scanning response message of serving BS broadcasts.

Just be provided with conventional ranging region if unite the neighbours station of scanning, the ranging code that MS can distribute in this zone emission, 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.The neighbours station of being united scanning receives the CDMA sign indicating number of launching that has distributed with expectation in conventional ranging region, code word is concentrated at random from initial code and selected.

If first frame of MS after the gathering time finishes can't obtain UL_MAP message, MS will end just to attempt 1 grade of associating process of carrying out with current neighbours station of being united scanning.After the termination, MS may carry out 0 grade of associating with this BS.

Step 1106～1113: identical with step 1003～1010 of 0 grade of associating among Figure 10, repeat no more here.

Among the described embodiment of Figure 11, control station is a serving BS broadcasts, when control station is high ability RS, coordinate request message by high ability RS to serving BS broadcasts emission combined parameters, the request serving BS broadcasts is coordinated combined parameters, after serving BS broadcasts is coordinated successfully, the combined parameters after coordinating is included in is transmitted to control RS in the combined parameters coordinate responses message, by control RS combined parameters is included in the MOB_SCN-RSP message and is transmitted to MS.

When low ability RS is arranged between neighbours station of being united scanning and the MS, the CDMA sign indicating number that emission is assigned with if the neighbours that MS unites scanning in the special ranging launching opportunity that is assigned with to quilt stand, then low ability RS also can receive the CDMA sign indicating number, this moment, low ability RS measured the CDMA sign indicating number that receives, generate CDMA sign indicating number report message, inform the neighbours station of being united scanning, i.e. the control station of low ability RS, the ranging parameters that the CDMA sign indicating number is measured.

2 grades of associatings are very close with 1 grade of associating, and difference is after step 2, and MS need not to wait for RNG-RSP message.Each switching target station will have the ranging parameters report of the correction of physical layer emission parameter, distance measuring states and issue neighbours base station, place earlier.This flow process comprises the steps:

Step 1201 among Figure 12 is in full accord with described step 1101 of Figure 11 and step 1102 to step 1205, repeats no more here.

Step 1206, the ranging parameters report that ranging parameters and distance measuring states will be carried in the neighbours station of being united scanning sends to the neighbours base station.

Step 1207, neighbours base station be the report of the ranging parameters that receives, and the neighbours that the united scanning available grade of service of standing is indicated and sent to serving BS broadcasts by backbone network.

Step 1208, all neighbours that united scanning that serving BS broadcasts will receive stand after the information that sends merges, send to MS, comprise in this message MS each united the grade of service indication at the neighbours station of scanning, the neighbours that united scanning stand and indicate to ranging parameters, distance measuring states, the grade of service of MS feedback.
