Description
Technical field
Present invention relates in general to wireless access system, and relate in particular to the transmission of messages in the wireless access system.
Background technology
Usually, in the progress of the international standard that is used for BWA, the system of IEEE802.16e comprises travelling carriage (MS), base station (BS) and as the ASA (authentication business mandate) of authentication management server.In this case, between MS and BS, stipulate common physical layer (PHY) and medium access control (MAC) layer.
1. scanning
Fig. 1 is scan request (for example, the MOB-SCN-REQ) block diagram of the format sample of message.Fig. 2 is scanning response (for example, MOB-SCN-RSP) the format sample block diagram of message.MS asks sweep spacing from the serving BS broadcasts of current access, with the signal quality of measuring neighbor bss with determine in switching the target BS that inserts.Carry out this request by scan request shown in Figure 1 (MOB-SCN-REQ) message.In response to this request, serving BS broadcasts sends scanning response (MOB-SCN-RSP) message to MS, and as shown in Figure 2, it comprises the information relevant with scanning.
2. park mode
The BWA dormant mode support is to minimize the power consumption of MS.The MS that is in park mode operates according to the sleep interval that increases with fixed rate.This sleep interval comprises audit window and sleep window.
By sleep request/response message the value of this audit window is fixed.For audit window, come instruct MS by the broadcasting MAC administrative messag (MOB-TRF-IND) that sends from BS, this message represents whether there is the downlink traffic that is used for MS, and whether needs are carried out range finding to be used for uplink communication maintenance and suitable down link type of coding maintenance according to signal quality.This sleep window is such interval, and during this period, MS receives minimal down link signal from BS, so that save energy.For sleep window, according to signal quality, MS carries out the scanning of the neighbor bss that is used to switch, and is used for the range finding of uplink communication maintenance and suitable down link type of coding and safeguards.
Fig. 3 is sleep request (for example, the MOB-SLP-REQ) block diagram of the format sample of message.Fig. 4 is dormancy response (for example, the MOB-SLP-RSP) block diagram of the format sample of message.Carry out the park mode initialization by between MS and BS, exchanging sleep request (MOB-SLP_REQ) message and dormancy response (MOB-SLP-RSP) message.Especially, in order to enter park mode from normal manipulation mode, MS sends sleep request (MOB-SLP-REQ) message to BS, as shown in Figure 3.Then, BS sends dormancy response (MOB-SLP-RSP) message to MS, as shown in Figure 4.
3. idle pulley
Idle pulley can make MS not be registered to specific BS by the cycle that receives only sends when moving through by a plurality of BS control regional downlink broadcasting service message (MOB-PAG-ADV), saves power consumption.At this idle pulley, MS is not used in the signaling requirement of switching.By the restriction action relevant with scanning, MS can save resource, as energy and connection ID.
Fig. 5 is un-register (de-registration) request (for example, the DREG-REQ) block diagram of the format sample of message.With reference to figure 5, MS sends un-register request (DREG-REQ) message to BS, is used for idle mode initialization.Respond this message, BS sends and comprises un-register order (DERG-CMD) message that allows relevant information with the idle pulley of MS.After sending DREG-CMD message to MS, BS release management resource, as be used for and being connected substantially of the MAC administrative messag exchange of MS, the main auxiliary connection that connects and be used for measured message (DHCP, TFTP etc.).
Fig. 6 is un-register order (for example, the DREG-CMD) block diagram of the format sample of message.As figure, Fig. 6 has illustrated the action code that comprises in this DREG-CMD message.According to the instruction by the action code indication, MS carries out action.For example, if code is 0X05, MS carries out the un-register process among the corresponding BS, and the initialization idle pulley.And even MS does not ask DREG-REQ message, BS also can send DREG-CMD (uncalled DREG-CMD) message with action code 0X05, so that MS enters idle pulley.
As mentioned above, give BS for one in MS transmission scan request (MOB-SCN-REQ), sleep request (MOB-SLP-REQ) and un-register request (DREG-REQ) message, the scanning in response that waits then from BS responds (MOB-SCN-RSP), repaiies in dormancy response (MOB-SLP-RSP) and un-register order (DREG-CMD) message.
Fig. 7 is the signal flow graph of signal scan request and the response message sample situation of losing.Fig. 8 is the signal flow graph of signal sleep request and the response message sample situation of losing.Fig. 9 is the signal flow graph of signal un-register request and the command messages sample situation of losing.With reference to figure 7-9, because limited wireless link circuit resource and wireless environment factor, MOB-SCN-REQ, the MOB-SLP-REQ and the DREG-REQ message that send from MS may not be transmitted to BS usually, and perhaps MOB-SCN-RSP in response, MOB-SLP-RSP, the DREG-CMD message that sends from BS may not send MS to usually.
In this case, owing in current BWA, do not have the processing procedure of regulation for the next one action of MS, therefore very possible MS or BS execution error action.
At idle pulley, BS discharges and connects (basic, main and auxiliary the connection) and send DERG-CMD message to MS.Therefore, if MS receives DREG-CMD message and retransmits the DREG-REQ message failure, then there is not available connection (the basic connection).And, even MS by DREG-REQ message request idle mode initialization, if sent so that MS enters DREG-CMD (uncalled DREG-CMD) information drop-out of idle pulley, then MS continues to operate under the normal manipulation mode.Yet after definite MS had entered idle pulley, BS discharged the management resource that is used for corresponding MS.After this, MS can not send message to BS.
