Technical field
The present invention relates to a kind of wireless communication system, more specifically, the present invention relates to be used for carrying out the method for network insertion at wireless communication system.
Background technology
The method for network access of the routine in the wireless communication system will be described with reference to Fig. 1, Fig. 2 and Fig. 3 below.Fig. 1 is the flow chart of the network insertion operation of the routine in the exemplary wireless communications system.
Subscriber station (SS) is powering on or when it loses and the communicating by letter or carry out network insertion when getting into new sub-district of its Serving cell.Network insertion relates to 10 steps.
With reference to Fig. 1, the initial access when powering on, SS searches for attachable base station (BS) through scanning descending (DL) channel.Because SS is not awareness network topology or structure at first, so the SS frequency of scanning neighbor BS one by one.
Through obtaining from detected BS after DL and up (UL) system information accomplish all system's settings, SS carries out the range finding step to detected BS at SS.SS is through making UL regularly synchronous with BS based on the range finding that connects.To the range finding based on connection, SS selects code division multiple access to insert (CDMA) sign indicating number randomly, and this CDMA sign indicating number is sent to BS.
Before accomplishing synchronously, the parameter that BS will adjust to the SS notice through ranging response (RNG-RSP) message.When having adjusted parameter, the state in RNG-RSP message is set to " in carrying out ".After having adjusted parameter fully, the RNG-RSP message that BS is set to state " success " is sent to SS.
SS and BS hold consultation to key property.If SS after authentication, obtain fully with BS synchronously, then SS registers to broadband network, and receives service through broadband network from BS.
During network insertion; SS and BS send and receiving media access control (MAC) message, for example advanced air interface distance measurement request/response (AAI_RNG-REQ/RSP), AAI SS key property request (AAI_SBC-REQ/RSP), AAI key management request (AAI_PKM-REQ/RSP), AAI register request/response (AAI_REG-REQ/RSP) etc.Usually, when SS sent MAC message, it all asked the UL resource allocation to send MAC message to BS.
Fig. 2 is the figure that is illustrated in the signal flow of operating to the bandwidth request (BR) of travelling carriage (MS) in the conventional wireless communication system, and Fig. 3 is the figure that is illustrated in the signal flow of the BR operation that is directed against MS in following GSM.
With reference to Fig. 2, in step S210, MS in ranging code from one group of sign indicating number that is classified as the BR sign indicating number option code, and selected sign indicating number is sent to BS, with request UL bandwidth.After MS successfully receives sign indicating number, in step S220, BS distributes the UL resource to MS, makes MS in the UL resource of distributing, to send bandwidth request (BW-REQ) message.Simultaneously, after sending sign indicating number, the MS Active Timer.If MS did not receive the UL resource allocation from BS before timer expiry, then MS resends this sign indicating number.Can be set to perhaps be worth T3 by timer based on the time-out time of the reservation of competing.
In step S230, MS sends BW-REQ message to BS in the UL resource of distributing.After receiving BW-REQ message from MS, in step S240, BS gives MS with the UL resource allocation, and in step S250, MS sends data to BS in the UL resource of distributing.
In the GSM of generation in future, BS had both supported common BR process of 5 steps, supported for 3 steps inserted the BR process fast again.Can be independent of the 3 steps quick BR of access process and carry out common BR process of 5 steps, perhaps can common BR process of 5 steps be gone on foot the retreatment pattern (fallback mode) that inserts the BR process fast as 3.
With reference to Fig. 3, insert fast in the BR process in 3 steps, in step S310, MS is sent to BS with fast access message and selection or that select according to predetermined rule at random BR designator.The BR designator can be BR sequence or BR sign indicating number, and fast access message bearing ULBR information, for example station identifier (STID:Station Identifier), request size etc.BS can send the affirmation sign (ACK) to the BR designator that receives to MS.
After successfully receiving BR designator and fast access message; In step S340; BS gives MS through advanced MAP (A-MAP) information unit of UL basic configuration (IE) with the UL resource allocation, 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 common BR process of 5 steps, MS sends the BR designator of selecting at random in step S310.After successfully receiving the BR designator, in step S320, BS distributes A-MAP IE to distribute the UL resource to MS through CDMA, makes MS can in the UL resource of distributing, send BW-REQ message.In step S330, MS sends BW-REQ message to BS in the UL resource of distributing.Then, in step S340, BS distributes A-MAP IE to distribute the UL resource to MS through UL basically, 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 is to BS request UL resource allocation, to transmit MAC message.As a result, network insertion is postponed.

To the method that is used for network insertion according to an illustrative embodiment of the invention be described with reference to Fig. 4 and Fig. 5 below.
Fig. 4 is the figure of the signal flow of the illustration method that is used for network insertion according to an illustrative embodiment of the invention, and Fig. 5 is the figure of the illustration signal flow that is used for method for network access in the time will retransferring media interviews control (MAC) message according to an illustrative embodiment of the invention.
With reference to Fig. 4; In step S401; Advanced travelling carriage (AMS:Advanced Mobile Station) is found advanced base station (ABS:Advanced Base Station); And advanced lead code (A lead code) realizes and the down link (DL) of ABS is synchronous through receiving from ABS, and in step S402, in superframe frame head (SFH:SuperFrame Header), receives basic parameter from ABS.During initial ranging, MS realizes with the UL of ABS synchronous 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 is then with comprising that initiatively advanced air interface ranging response (AAI_RNG-RSP) message of bandwidth indicator is replied AMS.Initiatively bandwidth indicator indication ABS will divide the UL bandwidth that is used in transmission 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 the ABS bandwidth on demand, ABS still will divide the UL bandwidth that is used in transmission MAC message to AMS.
Receive the AAI_RNG-RSP message with bandwidth indicator initiatively from ABS after, AMS keeps watch on advanced MAP information unit (A-A-MAP IE) and reaches the scheduled time slot that receives after the AAI_RNG-RSP message, to confirm whether ABS has distributed the UL bandwidth to AMS.If A-A-MAP IE has distributed bandwidth to AMS in step S407, 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.
To receiving AAI_SBC-RSP message preset time afterwards, AMS keeps watch on A-A-MAP IE to confirm whether ABS has distributed the UL bandwidth to AMS.If ABS has distributed the UL bandwidth through A-A-MAPIE to AMS in step S410, then AMS sends AAI key management request (AAI_PKM-REQ) message to ABS in the UL bandwidth of distributing in step S411.
In this way, after AMS sends response message, ABS divides the UL bandwidth that is used in next request message of transmission to AMS, up to having accomplished network insertion.
Reach preset time if AMS fails to receive the UL allocated bandwidth, then AMS carries out the BR process based on competition.This expression AMS option code from the one group of ranging code that is categorized as the BR sign indicating number, and the sign indicating number that will select is sent to ABS.
Simultaneously, if the UL insufficient bandwidth of distributing is to transmit MAC message, then AMS can send additional BR together with MAC message.That is, when sending MAC message, AMS can ask the bandwidth of adding.
When ABS fails when AMS receives MAC message, the AMS MAC message that retransfers.With reference to Fig. 5, the method for network access under MAC message re-transmission situation according to an illustrative embodiment of the invention will be described below.
With reference to Fig. 5, the A lead code realizes AMS and the DL of ABS is synchronous through receiving from ABS in step S501, and in SFH, receives basic parameter from ABS at step S502.During initial ranging, AMS realizes with the UL of ABS synchronous 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 that comprises the active bandwidth indicator in step S506.
Receive the AAI_RNG-RSP message with active bandwidth indicator from ABS after, AMS supervision A-A-MAP IE reaches and receives AAI_RNG-RSP message preset time afterwards, to confirm whether ABS has distributed the UL bandwidth to AMS.If in step S507, distributed the UL bandwidth through A-A-MAP IE to AMS, then AMS transmits AAI_SBC-REQ message to ABS in the UL bandwidth of distributing in step S508.
If ABS from the UL allocated bandwidth is failed to receive AAI_SBC-REQ message to transmit in the predetermined periods that the AAI_SBC-REQ corresponding time of message begins to AMS, then ABS is being used in the UL bandwidth that retransmits AAI_SBC-REQ message dividing to AMS in step S5Q9.AMS keeps watch on A-A-MAP IE during the predetermined periods that begins from the time that receives the mixing local negative response of automatic repeat requests (HARQ) (NACK), to confirm whether ABS has distributed the UL bandwidth to AMS.In step S510, if ABS has distributed the UL bandwidth through A-A-MAPIE to AMS, then AMS in the UL bandwidth of distributing to the ABS AAI_SBC-REQ message that retransfers.
To the method that is used for network insertion according to another illustrative embodiments of the present invention be described with reference to Fig. 6.
Because AMS can get rid of different fields from MAC message during network insertion, so can have different sizes by the MAC message that AMS transmitted.Therefore, if ABS then can produce unnecessary bandwidth consumption in the bandwidth of having distributed predetermined size during the network insertion under not from the situation of the request of AMS to AMS.
Therefore, ABS sends the AAI_RNG-RSP message that comprises bandwidth inquiry designator to AMS during network insertion, is used to transmit the bandwidth of BW-REQ message to the AMS inquiry, and does not need the request from AMS.Then, AMS sends the BW-REQ message that comprises the request size to ABS.
Fig. 6 is the figure of illustration according to the signal flow that is used for method for network access of another illustrative embodiments of the present invention.
With reference to Fig. 6, AMS finds ABS in step S601, and the A lead code realizes and the DL of ABS is synchronous through receiving from ABS, and in step S602, in SFH, receives basic parameter from ABS.During initial ranging, AMS realizes with the UL of ABS synchronous in step S603 and S604.
In step S605, AMS sends AAI_RNG-REQ message to ABS.ABS then replys AMS with the AAI_RNG-RSP message that comprises bandwidth inquiry designator in step S606.
Bandwidth inquiry designator indication ABS does not want can transmit to AMS inquiry AMS the UL bandwidth of BW-REQ message from the request ground of AMS.That is, ABS sends bandwidth inquiry designator to AMS in AAI_RNG-RSP message, is used for during network insertion, transmitting the UL bandwidth of BW-REQ message under not from the situation of the request of AMS to AMS inquiry AMS with indication ABS.
After receiving the AAI_RNG-RSP message with bandwidth inquiry designator, the distribution that AMS keeps watch on the UL bandwidth reaches from receiving the predetermined periods that AAI_RNG-RSP message begins to start at.If ABS has distributed the UL bandwidth to AMS in step S607, then AMS sends BW-REQ message to ABS in the UL bandwidth of distributing in step S608.BW-REQ message comprises the amount of bandwidth that AMS asks.In step S609, ABS then distributes the bandwidth of the size of being asked to AMS.AMS sends AAI_SBC-REQ message to ABS in the UL bandwidth of distributing in step S610.
ABS replys AMS with AAI_SBC-RSP message in step S611, and in step S612, distributes the UL bandwidth to AMS during the predetermined periods after sending AAI_SBC-RSP message.In step S613, AMS transmits the BW-REQ message that comprises the request size to AMS in the UL bandwidth of distributing.The UL bandwidth of the size that ABS is asked to the AMS distribution in step S614.
In step S615, AMS transmits AAI_PKM-REQ message to ABS in the UL bandwidth of distributing.If ABS is failing to receive AAI_PKM-REQ message from being assigned in the predetermined periods that the corresponding time of AMS begins with the UL bandwidth that is used to transmit AAI_PKM-REQ message, then ABS divides to AMS in step S616 and is used in the UL bandwidth that retransmits AAI_PKM-REQ message.AMS keeps watch on the distribution of UL bandwidth during the predetermined periods that begins from the time that receives the local NACK of HARQ.In step S617, if ABS has distributed the UL bandwidth to AMS, then AMS retransmits AAI_PKM-REQ message to ABS in the UL bandwidth of distributing in step S617.
To the method that is used for network insertion according to another illustrative embodiments of the present invention be described with reference to Fig. 7 below.
According to this illustrative embodiments, AMS divides the UL bandwidth that is used in next MAC message of transmission through sending the MAC message that comprises the active bandwidth indicator to ABS to the ABS request.AMS can comprise initiatively bandwidth indicator in each MAC message, divide with request to be used in the UL bandwidth that transmits next MAC message.Alternatively or additionally, AMS can ask ABS to be directed against employed each MAC distribution of messages UL bandwidth during network insertion through in AAI_RNG-REQ message, sending initiatively bandwidth indicator to ABS.In this illustrative embodiments, if ABS permits failing to receive MAC message from AMS before the timer expiration at BR, then ABS need not to divide the UL bandwidth that is used in re-transmission MAC message to AMS from the request ground of AMS.
Fig. 7 illustration according to the method that is used for network insertion of another illustrative embodiments of the present invention.
With reference to Fig. 7, AMS transmits the RNG-REQ message that comprises the active bandwidth indicator to ABS in step S701.Initiatively bandwidth indicator is used to ask ABS to need not to divide the UL bandwidth that is used in next MAC message of transmission to AMS from the request ground of AMS.AMS also can notify the size of next MAC message together with the active bandwidth indicator to ABS.
In step S702, ABS transmits to AMS and comprises to the response of active bandwidth indicator with about the RNG-RSP message of the information of time of distributing the UL bandwidth.Whether will need not request ground from AMS to the response of active bandwidth indicator indication ABS and divide to AMS and be used in the UL bandwidth that transmits SBC-REQ message, and can specify vertical shift or the subframe skew that is used in the time of the UL bandwidth that transmits SBC-REQ message from the time of transmitting RNG-RSP message to branch about the information of time of distributing the UL bandwidth.Can between ABS and AMS, preset the time of distributing the UL bandwidth, rather than distribute time of UL bandwidth, make and divide the UL bandwidth that is used in transmission SBC-REQ message to AMS in the predetermined periods of ABS after transmitting RNG-RSP message to the AMS notice.
In step S703, up to this frame or subframe squint the corresponding time or transmitting RNG-RSP message after the preset time in, ABS divides to AMS and is used in the UL bandwidth that transmits SBC-REQ message and activates BR allowance timer.When being assigned with when being used to transmit the UL bandwidth of SBC-RSP message, AMS also activates BR and permits timer.
AMS sends SBC-REQ message to ABS in the UL bandwidth of distributing in step S704.If ABS failed to receive SBC-REQ message before BR permits timer expiration, then ABS divides the UL bandwidth and the replacement BR that are used in re-transmission SBC-REQ message to permit timer to AMS in step S705.When AMS recognized through NACK that SBC-REQ message transmitted failure before its BR permits timer expiration, AMS kept watch on the distribution of UL bandwidth and in step S706, in the UL bandwidth of distributing, retransmits and comprises the initiatively SBC-REQ message of bandwidth indicator.
If ABS successfully receives SBC-REQ message, then ABS stops BR allowance timer.When recognizing that ABS successfully receives SBC-REQ message, AMS also stops its BR and permits timer.
Subsequently; ABS transmits SBC-RSP message to AMS in step S707; SBC-RSP message comprises to the response of bandwidth indicator initiatively and about the information of time of distributing the UL bandwidth; And with transmit the corresponding time of vertical shift that SBC-RSP message starts at after, in step S708, divide to be used in the UL bandwidth that transmits PKM-REQ message, and activate BR and permit timer to AMS.
In step S709, AMS sends PKM-REQ message to ABS in the UL bandwidth of distributing.
During network insertion, can permit timer by Application of B R, so that network insertion is faster.In addition, be used to transmit in request during the bandwidth of message of other purpose, can use BR to permit timer.
Utilize BR to permit timer, in case BR permits timer expiration, AMS is resend messages in the UL bandwidth of distributing immediately, and need not wait for the timer expiration up to the routine that is used to receive request message and response message.
In addition; When transmitter receives HARQ this locality NACK message; Use BR to permit timer and make transmitter to come to prepare apace the message re-transmission, and need not wait for up to the timer expiration that is used for confirming message transmission/reception through sending the active bandwidth indicator.
If confirmed the HARQ retransmission timer, then can replace BR to permit timer with the HARQ retransmission timer.In case the expiration of HARQ retransmission timer, ABS can automatically divide the UL bandwidth that is used in the message re-transmission to AMS.
