Description
Technical field
The present invention relates to control the method for wireless access, and more specifically, in the width wireless access system, carry out the method for handover.Though the present invention is suitable for range of application widely, be specially adapted to behind handover that mobile subscriber station effectively keeps park mode in the BWA pattern.
Background technology
BWA is supported in the park mode in the mobile subscriber station (MSS), so that reduce battery consumption.Park mode be included in MSS wherein not with base station transmits saving the sleep interval of electric energy, and between two park modes, take place to determine whether from the base station to the listening intervals of MSS communicating downlink business.
Based on the feature of the business of current selection, BWA comprises the Three Estate or the category of park mode.Park mode also can be expressed as the electric energy save mode.Exist and be further defined as the three class electric energy saving level model that electric energy is saved class parameter.Electric energy is saved class parameter 1 (" grade 1 ") and is comprised initial sleep window, the final window truth of a matter (base), final window index, the beginning frame number of audit window and sleep window parameter.And the purpose of grade 1 type is that it comprises existing Internet service or has the feature of the non real-time variable rate (Non-Real-TimeRate (NRTVR)) that changes transmission rate in conjunction with the feature such as the best achievement (Best Effort (BE)).
Electric energy saving class parameter 2 (" grade 2 ") searching combination changes the feature based on the non real-time variable rate (RT-VR) of the voice transfer (VoIp) of Internet protocol or transmission rate.Grade 2 comprises initial sleep window, the beginning frame number of audit window and sleep window parameter.
Electric energy is saved class parameter 3 (" grade 3 ") and is comprised MSS periodic transfer control messages and the description of downlink channel descriptions/uplink channel (DCD/UCD) and MOB-NBR-ADV message in park mode, is used to receive the information of the neighbor bss overlay area that handover uses or transmits the data of multiple access communication.Grade 3 comprises the final window truth of a matter, the beginning frame number of final window exponential sum dormancy parameter.
For grade 1, the listening intervals that can increase with special speed and the operation of sleep interval can influence the sleep operation of MSS.The duration of listening intervals is determined by MOB-SlP-REQ message and MOB-SLP-RSP message.MSS if MSS can enter dormancy from request base station (BS) transmits MOB-SlP-REQ message.MSS receives MOB-SLP-RSP message from BS, and wherein BS asks transmission response to this.During this listening intervals, MSS receives service indication message (MOB-TRF-IND), and it is the control messages of media interviews access control (MAC).From this message, MSS obtains about whether transmitting any downlink traffic or must not keeping continuing with ul transmissions the ranging process of the down link type of coding relevant with signal quality.
MSS only receives minimum down link signal from BS during sleep interval, to save electric energy.Even when dormancy, MSS can scanning neighbor base stations in the situation that must carry out handover, and carries out ranging process.
MSS in park mode receives MOB-TRF-IND message at listening intervals, and determines whether to continue park mode at sleep interval, stops park mode with the receiving downlink signal, or carries out ranging process.
Fig. 1 shows the operation of grade 1 park mode.In Fig. 1, MSS transmission BSMOB-SLR-RED message enters park mode (S11) to BS with request.MOB-SLR-RED message comprises about initial sleep interval, the information of final sleep interval and listening intervals.Can enough frame expression and initial sleep interval, the final sleep interval information relevant with listening intervals.
If BS allows MSS to enter park mode, then MSS receives MOB-SLR-RSP message (S12).MOB-SLR-RSP message comprises about initial sleep interval, final sleep interval, the information of listening intervals and park mode inlet point.Be included in the initial sleep interval of MOB-SLR-RSP, the information of final sleep interval and listening intervals can with the initial sleep interval of MOB-SLR-RED message, the information that contains in final sleep interval and the listening intervals is identical or different.
After receiving MOB-SLR-RSP message, MSS enters park mode, and remains on this pattern in the duration of regulation.When initial sleep interval was ended, MSS entered listening intervals.Receive MOB-SLR-IND message (S13) at listening intervals MSS, and if receive from any downlink traffic of BS transmission.
Do not exist downlink traffic when transmission, MSS to enter sleep interval subsequently and keep the regulation duration at park mode.This second or duration of sleep interval subsequently from the duration of first sleep interval measure.For example, the duration of second sleep interval can be the twice of the duration of first sleep interval.Subsequently, measure the duration of the 3rd sleep interval based on the size of second sleep interval.
After second sleep interval ended, MSS entered another listening intervals.Receive MOB-TRF-IND message (S14) and determine whether to exist any downlink traffic at listening intervals MSS.If there is downlink traffic, MSS stops park mode, returns to normal mode with from base station receiving downlink business.
But if do not detect any downlink traffic at listening intervals MSS, then the duration of sleep interval subsequently increases in the above described manner.Final sleep interval is mated in the such gradual increase of repetition in the sleep interval time-delay up to the duration of sleep interval duration.At this point, the duration of sleep interval remains on the duration that equates with final sleep interval.
The information of the final sleep interval that comprises in MOB-SLR-REQ/RSP message can be expressed by the final sleep window truth of a matter and final window index.Here, can user's formula 1 calculate final sleep interval.
[equation 1]
Final sleep window=final sleep window truth of a matter * 2
Final window index
If MSS must carry out the handover from park mode, for example, MSS enters the neighbor bss overlay area, stops park mode and carries out handover.About the increase of duration of sleep interval, the duration subsequently of the sleep interval of the MSS of park mode is than the longer duration of previous sleep interval as mentioned above.Determine do not have the communicating downlink business if its reason is BS, exist in the high probability that downlink traffic does not take place next sleep interval at current sleep interval.Therefore, BS is increased in consistent up to duration of this sleep interval and final sleep interval of sleep interval duration behind each listening intervals.
But, if MSS returned to park mode after MSS termination park mode to carry out handover, was then finished handover.At this moment, MSS must repeat to strengthen the processing of sleep interval duration.In other words, as beginning to do in processing procedure, MSS must send MOB-SLP-REQ message to BS, and request enters park mode.Therefore, MSS must be by reentering park mode to BS request, and gradual from duration that initial sleep interval begins to strengthen sleep interval.
Ordinary circumstance is, no matter whether the business transmission of down link takes place, and the handover of generation as a result that moves as MSS.Therefore because handover takes place, MSS from beginning or from reach certain sleep interval or even the initial sleep interval of final sleep interval to reenter park mode be uneconomic.And because duration of sleep interval reenters from beginning, listening intervals occurs more continually, so unnecessarily transmits MOB-TRF-IND.
For example, if the MSS that has 1024 frames at sleep interval carries out handover, in order to reach the park mode that has 1024 frames in the sleep interval in new sub-district, suppose that initial sleep interval comprises two frames, MSS must receive nine times MOB-TRF-IND message.As a result, transmit and receive nine MOB-TRF-IND message waste resources and electric energy.
About grade 2, listening intervals and the sleep interval of duration take place the park mode of MSS according to having fixedly.Fig. 2 illustrates the operation of the park mode of grade 2.In Fig. 2, MSS enters park mode (S21) to BS transmission MOB-SLP-REQ message with request.MOB-SLP-REQ message comprises the information about initial sleep interval and listening intervals.Can enough frame expression and initial sleep interval, the final sleep interval information relevant with listening intervals.
If BS allows MSS to enter park mode, then MSS receives MOB-SLR-RSP message (S22).MOB-SLR-RSP message comprises the information about initial sleep interval, listening intervals and park mode inlet point.Be included in the initial sleep interval of MOB-SLR-RSP, the information that the information of final sleep interval and listening intervals can contain with the initial sleep interval and the listening intervals of MOB-SLR-RED message is identical or different.
After receiving MOB-SLR-RSP message, MSS enters park mode, and remains on this pattern in the duration of regulation.When initial sleep interval was ended, MSS entered listening intervals.During listening intervals, MSS obtains the corresponding cycle, with the Uplink/Downlink business of maintenance with BS, and can receive from the downlink traffic (S23) of BS transmission.
Behind listening intervals, MSS reenters the park mode of the duration that is used for initial sleep interval.And, MSS MSS can the receiving downlink business sleep interval return to listening intervals after ending.If MSS wishes to stop park mode, can use MOB-SLP-REQ at this listening intervals, stop park mode (S24) with request, and to the BS transmitting user data.
But, in the time of in park mode, if MSS returns to normal mode to carry out handover after stopping park mode, finish handover after MSS reenter park mode.At this moment, MSS must be as advancing into park mode earlier, to BS transmission MOB-SLP-REQ message and reception MOB-SLP-RSP message.As a result, MSS can not reenter park mode immediately after finishing handoff operation, but the process that must repeat to enter park mode.
For grade 3, MSS enters park mode based on the message by cycle ranging process transmission.Fig. 3 illustrates the operation of grade 3 park modes.In Fig. 3, MSS obtains uplink transport parameter by carrying out ranging process periodically, with the ul transmissions of maintenance with BS.That is, MSS transmits distance measurement request (RNG-REQ) message (S31) and receives ranging response (RNG-RSP) message from BS.
RNG-RSP message comprises that electric energy is saved class parameter and comprised final sleep interval and park mode inlet point information about the information of uplink transport parameter and electric energy saving class parameter.MSS receives the duration that enters park mode and keep final sleep interval at park mode after the RNG-RSP message.After this sleep interval ended, MSS communicated by letter in normal mode with BS, and carry out handover procedure periodically (S33, S34).During ranging process, MSS receives RNG-RSP message (S34), and if electric energy save parameter and be included in the RNG-RSP message, then MSS enters park mode according to RNG-RSP message.But, if MSS stops park mode, and turn back to normal mode to carry out handoff operation, then MSS is carrying out reentering park mode behind the handoff operation.At this moment, MSS must transmit identical RNG-REQ message or sleep request message as transmitting before carrying out handover.As a result, MSS must receive sleep request message or RNG-RSP message before being allowed to reenter park mode.
Summary of the invention

Embodiment
In detail with reference to the embodiment of the invention, these embodiment are shown in the drawings below.Use same tag to represent same or similar part to the greatest extent in the accompanying drawing everywhere as much as possible.
Message for save the operation of class parameter about each electric energy in park mode has MOB-SLP-REQ, MOB-SLP-RSP and MOB-TRF-IND message.MOB-SLP-REQ message is the MAC control messages of MSS request park mode.This message comprises the information about sleep interval and listening intervals.And MOB-SLP-RSP message is that request provides the MAC control messages of answering or answering to MSS.This message comprises the information whether request of park mode is allowed to, and about sleep interval, the information of listening intervals and dormancy identification.In addition, MSS uses MOB-TRF-IND message to receive service indication message, to determine to keep park mode.Stop park mode with the receiving downlink business, or when park mode, carry out ranging process.
Ranging response message comprises the electric energy saving class parameter of variable-length parameter, and it can be made of the TLV field of a plurality of sealings.That is to say that when needs, electric energy is saved class parameter can comprise the parameter that is made of the various factors in the particular type parameter.
Fig. 4 illustrates first example of transmission park mode information.Among Fig. 4, when in park mode, MSS is to BS transmission handover indication (MOB-HO-IND) message of serving, so that enter the handover from the BS that serving to target BS.If MSS must keep park mode behind handover, when carrying out handover, the BS that is serving in ranging process can transmit the information of the size of final sleep window to target BS.More specifically, the BS that is serving can be by the information (S42) of RNG-REQ transmission of messages about last sleep interval.The ul transmissions relevant with the down link type of coding with the target BS maintenance and the processing procedure of signal quality are represented in range operation.
The example of RNG-REQ message is shown in the table 1.

Save class parameter by add electric energy to RNG-REQ message, with the example of table 2 similarly, MSS can wish to keep the message of park mode to purpose BS transmission behind handover about MSS.
After MSS carries out the handover of target BS (S43) and if target BS when allowing MSS to enter park mode, MSS receives the MOB-SLP-RSP message of non-request, it allows MSS to enter park mode (S44) in target BS.MOB-SLP-RSP message comprises the information about the duration of the initial sleep interval of MSS.The duration of initial sleep interval can be identical or different with the extension time of the previous sleep interval that comprises in RNG-REQ message.That is, target BS determines whether to set the value of initial sleep interval identical with previous value before the handover.Previous sleep interval is the sleep interval of the MSS among the BS that is serving before handover.
Another embodiment of the present invention is, as response to distance measurement request message, BS2 can use with table 2 in identical electric energy save class parameter transmission ranging response message.At this moment, electric energy saving parameter is included in the ranging response message.As a result, with respect to Fig. 4, MSS can enter park mode under the situation that does not receive uncalled sleep response message.
In uncalled MOB-SLP-RSP message, the value of initial sleep interval is restricted to 8.If the size of sleep window is greater than 2 before handover
8-1 frame then can not be explained MOB-SLP-RSP message.In addition, in order to explain big initial sleep window, the information in table 3 can be included in the uncalled MOB-SLP-RSP message.Table 3 is included in the information of the initial sleep interval that comprises in the uncalled MOB-SLP-RSP message.

After MSS carries out handover (S54), if MSS wishes to stay park mode, the BS that is then serving transmits the information of last sleep interval to target BS.At this, this MSS can with the previous sleep window value of the sleep interval of the BS that is serving irrespectively determine sleep interval needs initial sleep window value and transmit this information to target BS.
The previous sleep window value of sleep interval can be passed through the MOB-SLP-REQ transmission of messages to target BS behind the handover.Subsequently, target BS can be transmitted initial sleep window value (S56) to MSS by MOB-SLP-RSP message.Here, can be identical or different from the initial sleep window value of the sleep interval of MSS transmission with initial sleep window value from the sleep interval of target BS transmission.
In uncalled MOB-SLP-RSP message, be limited to 8 in the initial sleep window.If the sleep window size is greater than 2 before the handover
8-1 frame then can not be explained MOB-SLP-RSP.Therefore, MOB-SLP-REQ/RSP message need prolong initial sleep window size, to represent big initial sleep window.Table 5 illustrates the form according to the MOB-SLP-REQ message of first example of initial sleep window size transmission method.
