With reference to Fig. 1, for initial access when powering on, SS searches for attachable base station (BS) by scanning descending (DL) channel.Because the initial not awareness network topology of SS or structure, so the frequency of SS scanning neighbor BS one by one.
After SS passes through to complete all Operation system setting from the BS acquisition DL detected and up (UL) system information, SS performs the ranging step for the BS detected.SS is by making UL timing synchronous with BS based on the range finding connected.For the range finding based on connection, SS selects code division multiple access to access (CDMA) code randomly, and this CDMA code is sent to BS.
Before synchronously completing, BS notifies the parameter that will adjust to SS by ranging response (RNG-RSP) message.When have adjusted parameter, the state in RNG-RSP message is set to " in carrying out ".After have adjusted parameter completely, the RNG-RSP message that state is set to " success " by BS is sent to SS.
SS and BS holds consultation to key property.If it is synchronous that SS obtains with BS after authentication completely, then SS is registered in broadband network, and to be received from BS by broadband network and serve.
During network insertion, SS and BS sends and receiving media access control (MAC) message, such as advanced air interface distance measurement request/response (AAI_RNG-REQ/RSP), AAI SS key property request/response (AAI_SBC-REQ/RSP), AAI Key Management Request/response (AAI_PKM-REQ/RSP), AAI registration request/response (AAI_REG-REQ/RSP) etc.Usually, when SS sends MAC message, it all asks UL Resourse Distribute to send MAC message to BS.
Fig. 2 is the figure being illustrated in the signal stream operated for the bandwidth request (BR) of travelling carriage (MS) in conventional wireless communication system, and Fig. 3 is the figure being illustrated in the signal stream operated for the BR of MS in following mobile communication system.
With reference to Fig. 2, in step S210, MS is classified as option code the code of BR code from one group in ranging code, and selected code is sent to BS, to ask UL bandwidth.After successfully receiving code from MS, in step S220, BS distributes UL resource to MS, makes MS can send bandwidth request (BW-REQ) message in the UL resource of distributing.Meanwhile, after transmission code, MS Active Timer.If MS did not receive UL Resourse Distribute from BS before timer expiry, then MS resends this code.Can be the reserved time-out time based on competition or value T3 by set timer.

In the mobile communication system of future generation, BS had both supported the common BR process of 5 step, supported that again 3 steps access BR process fast.BR process can be accessed fast independent of 3 steps and perform the common BR process of 5 step, or the common BR process of 5 step can be accessed fast the retreatment pattern (fallback mode) of BR process as 3 steps.
With reference to Fig. 3, access in BR process fast in 3 steps, in step S310, MS by fast access message and Stochastic choice or be sent to BS according to the BR designator of predetermined rules selection.BR designator can be BR sequence or BR code, and fast access message bearing ULBR information, such as station identifier (STID:StationIdentifier), request size etc.BS can to the acknowledgement indicator (ACK) of MS transmission for the BR designator received.
After successfully receiving BR designator and fast access message, in step S340, BS passes through advanced MAP (A-MAP) information unit (IE) of UL basic configuration by UL Resourse Distribute to MS, and in step S350, MS sends data to BS in the UL resource of distributing.In step S350, MS can send (piggyback) additional ULBR information together with data.
In the common BR process of 5 step, MS sends the BR designator of Stochastic choice in step S310.After successfully receiving BR designator, in step s 320, BS distributes A-MAP IE by CDMA and distributes UL resource to MS, makes MS can send BW-REQ message in the UL resource of distributing.In step S330, MS sends BW-REQ message to BS in the UL resource of distributing.Then, in step S340, BS substantially distributes A-MAP IE by UL and distributes UL resource to MS, and in step S350, MS sends data in the UL resource of distributing.In step S350, MS can send additional UL BR information together with data.
Usually, during network insertion, MS sends MAC message each time, and MS asks UL Resourse Distribute, to transmit MAC message to BS.As a result, network insertion is delayed by.

Below with reference to Fig. 4 and Fig. 5, the method for network insertion is according to an illustrative embodiment of the invention described.
Fig. 4 is the figure of the signal stream of the method for network insertion illustrated according to an illustrative embodiment of the invention, and Fig. 5 is the figure of the signal stream for method for network access when the media interviews that will retransfer control (MAC) message illustrated according to an illustrative embodiment of the invention.
With reference to Fig. 4, in step S401, advanced travelling carriage (AMS:Advanced Mobile Station) finds advanced base station (ABS:Advanced Base Station), and realize synchronous with the down link (DL) of ABS by receiving advanced lead code (A lead code) from ABS, and in step S402, in superframe frame head (SFH:SuperFrame Header), receive basic parameter from ABS.During initial ranging, MS realizes synchronous with the UL of ABS in step S403 and S404.
In step S405, AMS sends advanced air interface distance measurement request (AAI_RNG-REQ) message to ABS.In step S406, ABS then replys AMS by advanced air interface ranging response (AAI_RNG-RSP) message comprising initiatively bandwidth indicator.Initiatively bandwidth indicator instruction ABS will divide the UL bandwidth being used in and transmitting MAC message to AMS, and need not receive bandwidth request (BR) from AMS.In other words, ABS sends initiatively bandwidth indicator to AMS in AAI_RNG-RSP message, although to indicate AMS not to ABS bandwidth on demand, ABS still will divide the UL bandwidth being used in and transmitting MAC message to AMS.
After receive the AAI_RNG-RSP message with initiatively bandwidth indicator from ABS, AMS monitors that advanced MAP information unit (A-A-MAP IE) reaches the scheduled time slot received after AAI_RNG-RSP message, to determine whether ABS is assigned with UL bandwidth to AMS.If A-A-MAP IE is assigned with bandwidth to AMS in step S 407, then in step S408, AMS sends AAI subscriber station key property request (AAI_SBC-REQ) message to ABS in the UL bandwidth of distributing.In step S409, ABS then replys AMS with AAI subscriber station key property response (AAI_SBC-RSP) message.
For the predetermined time received after AAI_SBC-RSP message, AMS monitors that A-A-MAP IE is to determine whether ABS is assigned with UL bandwidth to AMS.If ABS is assigned with UL bandwidth by A-A-MAPIE to AMS in step S410, then AMS sends AAI Key Management Request (AAI_PKM-REQ) message to ABS in step S411 in the UL bandwidth of distributing.
In this way, after sending response message to AMS, ABS divides the UL bandwidth being used in and transmitting next request message to AMS, until complete network insertion.
If AMS fails to receive UL allocated bandwidth reach predetermined time, then AMS performs the BR process based on competition.This represents that AMS is from option code the one group of ranging code being categorized as BR code, and the code of selection is sent to ABS.
Meanwhile, if the UL bandwidth of distributing is not enough to transmit MAC message, then AMS can send additional BR together with MAC message.That is, while transmission MAC message, AMS can ask the bandwidth of adding.
When ABS fails to receive MAC message from AMS, AMS retransfers MAC message.With reference to Fig. 5, the method for network access in MAC retransmitting message situation according to an illustrative embodiment of the invention will be described below.
Realize with the DL of ABS synchronous by receiving A lead code from ABS with reference to Fig. 5, AMS in step S501, and in SFH, receive basic parameter from ABS in step S502.During initial ranging, AMS realizes synchronous with the UL of ABS in step S503 and S504.
In step S505, AMS sends AAI_RNG-REQ message to ABS.ABS then replys AMS with the AAI_RNG-RSP message comprising initiatively bandwidth indicator in step S506.
After receive the AAI_RNG-RSP message with initiatively bandwidth indicator from ABS, AMS monitors that A-A-MAP IE reaches the predetermined time received after AAI_RNG-RSP message, to determine whether ABS is assigned with UL bandwidth to AMS.If be assigned with UL bandwidth by A-A-MAP IE to AMS in step s 507, then AMS transmits AAI_SBC-REQ message to ABS in step S508 in the UL bandwidth of distributing.
If ABS is failing to receive AAI_SBC-REQ message to transmit in the predetermined period the AAI_SBC-REQ message corresponding time from by UL allocated bandwidth to AMS, then ABS is dividing the UL bandwidth being used in and retransmitting AAI_SBC-REQ message in step S5Q9 to AMS.AMS monitors A-A-MAP IE, to determine whether ABS is assigned with UL bandwidth to AMS during the predetermined period from receiving the time of hybrid automatic repeat-request (HARQ) local negative response (NACK).In step S510, if ABS is assigned with UL bandwidth by A-A-MAPIE to AMS, then AMS to retransfer AAI_SBC-REQ message to ABS in the UL bandwidth of distributing.
With reference to Fig. 6, the method for network insertion according to another illustrative embodiments of the present invention is described.
Because AMS can get rid of different fields from MAC message during network insertion, so the MAC message transmitted by AMS can have different sizes.Therefore, if ABS is assigned with the bandwidth of pre-sizing during network insertion to AMS when the request not from AMS, then unnecessary bandwidth consumption can be produced.
Therefore, ABS sends the AAI_RNG-RSP message comprising bandwidth inquiry designator during network insertion to AMS, to the bandwidth of AMS inquiry for transmitting BW-REQ message, and need from the request of AMS.Then, AMS sends the BW-REQ message comprising request size to ABS.
Fig. 6 illustrates the figure according to the signal stream for method for network access of another illustrative embodiments of the present invention.
Find ABS in step s 601 with reference to Fig. 6, AMS, and realize synchronous with the DL of ABS by receiving A lead code from ABS, and in SFH, receive basic parameter from ABS in step S602.During initial ranging, AMS realizes synchronous with the UL of ABS in step S603 and S604.
In step s 605, AMS sends AAI_RNG-REQ message to ABS.ABS then replys AMS with the AAI_RNG-RSP message comprising bandwidth inquiry designator in step S606.
Bandwidth inquiry designator instruction ABS wants to inquire about to AMS the UL bandwidth that AMS can transmit BW-REQ message less than the request from AMS.That is, ABS sends bandwidth inquiry designator to AMS in AAI_RNG-RSP message, inquires about AMS for transmitting the UL bandwidth of BW-REQ message during network insertion to indicate ABS when not having the request from AMS to AMS.
After receiving the AAI_RNG-RSP message with bandwidth inquiry designator, AMS monitors that the distribution of UL bandwidth reaches the predetermined period of starting at from receiving AAI_RNG-RSP message.If ABS is assigned with UL bandwidth to AMS in step S607, then AMS sends BW-REQ message to ABS in step S608 in the UL bandwidth of distributing.BW-REQ message comprises the amount of bandwidth that AMS asks.In step S609, ABS then distributes the bandwidth of the size of asking to AMS.AMS sends AAI_SBC-REQ message to ABS in step S610 in the UL bandwidth of distributing.
ABS replys AMS by AAI_SBC-RSP message in step s 611, and in step S612, during sending the predetermined period after AAI_SBC-RSP message, distributes UL bandwidth to AMS.In step S613, AMS transmits the BW-REQ message comprising request size in the UL bandwidth of distributing to AMS.ABS distributes the UL bandwidth of the size of asking in step S614 to AMS.
In step S615, AMS transmits AAI_PKM-REQ message to ABS in the UL bandwidth of distributing.If ABS fails to receive AAI_PKM-REQ message within the predetermined period from being assigned to the AMS corresponding time with the UL bandwidth for transmitting AAI_PKM-REQ message, then ABS divides the UL bandwidth being used in and retransmitting AAI_PKM-REQ message in step S616 to AMS.AMS monitors the distribution of UL bandwidth during the predetermined period from receiving the time of the local NACK of HARQ.In step S617, if ABS is assigned with UL bandwidth to AMS, then AMS retransmits AAI_PKM-REQ message to ABS in step S617 in the UL bandwidth of distributing.
Below with reference to Fig. 7, the method for network insertion according to another illustrative embodiments of the present invention is described.
According to this illustrative embodiments, AMS by sending the MAC message that comprises initiatively bandwidth indicator to ABS to ABS request dispatching for transmitting the UL bandwidth of next MAC message.AMS can comprise initiatively bandwidth indicator, with request dispatching for transmitting the UL bandwidth of next MAC message in each MAC message.Alternatively or additionally, AMS can ask ABS to distribute UL bandwidth for each the MAC message used during network insertion by sending active bandwidth indicator to ABS in AAI_RNG-REQ message.In this illustrative embodiments, if ABS failed to receive MAC message from AMS before BR permits timer expiration, then ABS divides to AMS the UL bandwidth being used in and retransmitting MAC message without the need to the request from AMS.
Fig. 7 is exemplified with the method for network insertion of another illustrative embodiments according to the present invention.
Transmit the RNG-REQ message comprising initiatively bandwidth indicator in step s 701 to ABS with reference to Fig. 7, AMS.Initiatively bandwidth indicator divides to AMS the UL bandwidth being used in and transmitting next MAC message without the need to the request from AMS for asking ABS.AMS also can notify the size of next MAC message to ABS together with active bandwidth indicator.
In step S702, ABS transmits the RNG-RSP message comprised the response of active bandwidth indicator and the information about the time of distribution UL bandwidth to AMS.Whether the response instruction ABS for active bandwidth indicator divides to AMS the UL bandwidth being used in and transmitting SBC-REQ message by without the need to the request from AMS, and can specify from transmitting the time of RNG-RSP message to the vertical shift or the sub-frame offset that divide the time being used in the UL bandwidth transmitting SBC-REQ message about the information of the time of distributing UL bandwidth.The time of distributing UL bandwidth can be preset between ABS and AMS, instead of distribute the time of UL bandwidth to AMS notice, make to divide to AMS the UL bandwidth being used in and transmitting SBC-REQ message in the predetermined period of ABS after transmission RNG-RSP message.
In step S703, until time corresponding with this frame or sub-frame offset or within the time of presetting of transmitting RNG-RSP message, ABS divides the UL bandwidth that is used in and transmits SBC-REQ message to AMS and activates BR and permits timer.When being assigned with the UL bandwidth for transmitting SBC-RSP message, AMS has also activated BR and has permitted timer.
AMS sends SBC-REQ message to ABS in step S704 in the UL bandwidth of distributing.If ABS permits failing to receive SBC-REQ message before timer expiration at BR, then ABS divides the UL bandwidth that is used in and retransmits SBC-REQ message to AMS and resets BR and permits timer in step S705.When by NACK, AMS recognized that SBC-REQ message transmitted unsuccessfully before its BR permits timer expiration, AMS monitors the distribution of UL bandwidth and in step S706, retransmits the SBC-REQ message comprising the wide designator of main belt in the UL bandwidth of distributing.
If ABS successfully receives SBC-REQ message, then ABS stops BR permitting timer.When recognizing that ABS successfully receives SBC-REQ message, AMS also stops its BR to permit timer.
Subsequently, ABS transmits SBC-RSP message to AMS in step S707, SBC-RSP message comprises for the response of active bandwidth indicator and the information of the time about distribution UL bandwidth, and after the time corresponding with the vertical shift that transmission SBC-RSP message is started at, in step S708, divide the UL bandwidth being used in and transmitting PKM-REQ message to AMS, and activate BR allowance timer.
In step S709, AMS sends PKM-REQ message to ABS in the UL bandwidth of distributing.
BR can be applied permit timer, to make network insertion faster during network insertion.In addition, during asking the bandwidth of message for transmitting other object, BR can be used to permit timer.
Utilize BR to permit timer, once BR permits timer expiration, AMS can resend messages in the UL bandwidth of distributing immediately, and does not need to wait for until for the timer expiration of the routine that receives request message and response message.
In addition, when transmitter receives HARQ this locality NACK message, using BR to permit timer makes transmitter can prepare retransmitting message rapidly by sending initiatively bandwidth indicator, and does not need to wait for until for determining the timer expiration that message send/receive.
If determine HARQ retransmission timer, then BR can be replaced to permit timer with HARQ retransmission timer.Once HARQ retransmission timer expires, ABS automatically can divide to AMS the UL bandwidth being used in retransmitting message.
With reference to Fig. 8, the method for network insertion according to another illustrative embodiments of the present invention is described.
According to another illustrative embodiments, AMS network after the handover uses the wide designator of main belt and BR to permit timer again between access periods.
Fig. 8 illustrates the figure according to the signal stream for method for network access of another illustrative embodiments of the present invention.
In step S801, handover request (HO-REQ) message is sent to service ABS with reference to Fig. 8, AMS.Service ABS replys AMS with handoff response (HO-RSP) message in step S802.HO-RSP message can comprise the information about activationary time, and this information represents that service ABS will send quick distance measurement IE to AMS after the time corresponding with activationary time+timer value T55.Thus, AMS can obtain the non-ranging opportunity based on competition for AMS.
AMS sends to ABS and switches instruction (HO-IND) message in step S803.When receiving quick distance measurement IE from ABS in step S804, AMS activates BW and permits timer.ABS also activates BR and permits timer after transmission quick distance measurement IE.In step S805, AMS sends RNG-REQ message to ABS in the UL bandwidth of distributing.RNG-REQ message comprises initiatively bandwidth indicator.
If ABS failed to receive RNG-REQ message before BR permits timer expiration, then ABS divides the UL bandwidth being used in and retransmitting RNG-REQ message in step S806 to AMS.Then, AMS retransmits RNG-REQ message to ABS in step S807 in the UL bandwidth of distributing.
After successfully receiving RNG-REQ message, ABS sends RNG-RSP message to AMS in step S808, and wherein, described RNG-RSP message comprises for the response of active bandwidth indicator and the information of the time about distribution UL bandwidth.
ABS divides the UL bandwidth being used in and transmitting SBC-REQ message in step S809 to AMS, and activates BR allowance timer.After receiving SBC-REQ message from AMS, ABS stops BR permitting timer in step S810, and replys AMS with SBC-RSP message in step S811.
Can obviously find out from the above description, according to an illustrative embodiment of the invention, BS distributes UL bandwidth without the need to the request from MS to MS, makes MS send MAC message by the UL bandwidth of distributing.Therefore, the network insertion of MS is not delayed by.
