Description
Technical field
The present invention relates to field of wireless communications systems, relate in particular to inserting of microwave whole world interoperability (WiMAX, World Interoperability for Microwave Access) method and the device of a kind of detection portable terminal (MS, Mobile Station) off-grid in the communication system.
Background technology
The WiMAX authentication main member of industry alliance comprises equipment manufacturers, device supplier, operator etc., main task is by product being carried out the authentication of compatibility and interoperability, eliminate the obstacle of IEEE802.16 standard application, enlarge the range of application of IEEE802.16 standard.The IEEE802.16 series standard has defined the wireless access technology air interface standard of WiMAX, and representative standard comprises that 802.16d fixed wireless access standard and 802.16e mobile wireless insert standard.
The WiMAX communication system mainly is made up of system equipment and terminal equipment.WiMAX network work group (NWG) agreement specified in more detail the system equipment framework of WiMAX, the WiMAX system equipment is mainly by access service network (ASN, Access Service Network) and connectivity serving network (CSN, ConnectionService Network) two parts constitute.ASN mainly comprises base station (BS, Base Station) and two network elements of ASN gateway (ASN GW, ASN Gateway) again.Terminal equipment inserts the WiMAX network by connecting BS.
The roughly flow process of a MS access WiMAX network comprises that mainly step 101 is to 105 as shown in Figure 1: channel synchronization, and to set up the space interface signaling management and connect, capability negotiation is set up the medium connection and is carried out media data communication.If a step failure is wherein arranged, then all can return back to and attempt again inserting.Wherein, the process of channel synchronization be divided into down channel synchronously and up channel synchronous, up channel synchronously with set up space interface signaling and manage the process that the process that is connected is referred to as range finding (Ranging) again.
It is synchronous that MS carries out down channel, and the signal that can correctly receive BS has just entered the process of range finding later on.Range finding is a key concept in the WiMAX network, it is divided into two stages, phase I MS sends random code word on up common signal channel, purpose is that the physical parameter of adjusting MS comprises time migration, frequency shift (FS) and transmitting power etc., and uplink bandwidth application; Second stage is that initial ranging (Initial Ranging) stage: MS inserts for sending Initial Ranging message request on the upstream bandwidth of its distribution at BS, BS receives Initial Ranging message later on for the management of MS assignment signalling connects, and notifies MS in response message.
The unique identification of MS in the WiMAX network is medium access control (MAC, the MediumAccess Control) address of MS, so can not have two MS that MAC Address is identical in the WiMAX network.In order to prevent disabled user's attack, if there has been the MS of certain particular mac address in the current WiMAX network, when the MS transmission Initial Ranging message request access of identical MAC Address was arranged again, this MS will directly be refused.
It is unusual as hardware fault, enter screen etc. suddenly that the MS off-grid is meant that MS takes place, and the situation that does not have enough time to notify the one-sided network of BS to withdraw from.The MS off-grid is avoiding greatly of wireless communication system, because this moment, BS was not known MS off-grid, BS has still kept local processing resource and valuable radio open resource for this MS.Therefore, BS must take some measures and detect the MS off-grid, prevents that resource from hanging for a long time even forever.
In addition, wireless communication system have channel condition complicated and changeable, be subjected to the characteristics such as influence of multiple different declines easily.Therefore MS may be in a period of time wireless signal acute exacerbation and cause communication disruption with BS, such as MS moves to the blind area.The MS wireless signal must compatiblely arrive the demand that the MS sort signal worsens in the time of the BS design, be the MS reservation of resource, so that can recover communication rapidly after improving.
More than two kinds of situations obviously have contradiction, on the one hand BS wishes can detect the MS communication disruption as early as possible and off-grid, for compatible MS wireless signal worsens, needs the reservation of resource for MS again on the other hand.Therefore prior art all takes the method for a compromise promptly to adopt a relatively long off-grid detection time in design BS.
Yet this brings another problem again: if MS breaks down and off-grid, wish to insert again at once, will not insert.Because the off-grid of BS is very long detection time, this MS still exists in the WiMAX network at this moment, and the MS of identical MAC Address does not allow to insert.Typical situation is that MS breaks down, and does not but insert behind the power-off restarting, and this can have a strong impact on the user and experience.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further elaborated.
BS of the present invention detects the method for MS off-grid and handles in two kinds of situation, and a kind of is basic MS off-grid testing process, the off-grid testing process when another kind is MS request access.
As shown in Figure 2, basic MS off-grid testing process may further comprise the steps:
The specific implementation process of " in off-grid sense cycle T; BS detects the current quality of uplink signal of MS " is: when off-grid sense cycle T begins, the quality of uplink signal that BS just begins to detect MS finishes until off-grid sense cycle T, when off-grid sense cycle T finished, BS preserved the value of the current quality of uplink signal of detected MS.
Wherein, off-grid sense cycle T picks up counting after the Ranging process is finished, and at all MS in the network unified off-grid sense cycle T can be set.In addition, the concrete numerical value of off-grid sense cycle T can be set according to the actual requirements.Generally speaking, T sets shortlyer with the off-grid sense cycle, and so the reason of setting will be mentioned hereinafter.
Step 202～204, BS judges the current quality of uplink signal of MS whether less than default quality of uplink signal detection threshold Th, if the testing result of then putting current off-grid sense cycle T is 0, then execution in step 205; Otherwise the testing result of putting current off-grid sense cycle T is 1, then returns step 201, promptly enters new off-grid sense cycle.
Wherein, the concrete root of number of quality of uplink signal detection threshold Th border requirements set factually.
Wherein, the quality of uplink signal that detects MS specifically can detect signal strength signal intensity, the signal to noise ratio (CINR of MS, carrier-to-interference-and-noise ratio) or the error rate etc., in also can signal strength signal intensity, CINR and the error rate of joint-detection MS any two, or above-mentioned three parameters of joint-detection, concrete detection means can be decided according to the actual requirements.
For example, when the CINR of joint-detection MS and the error rate, need respectively the CINR and the error rate to be set CINR detection threshold Th ' and error rate detection threshold Th ", more detected respectively afterwards CINR and CINR detection threshold Th ' and the detected error rate and error rate detection threshold Th ".Can find by above-mentioned example, when joint-detection, need the relevant detection thresholding be set, more detected then numerical value and relevant detection thresholding each parameter.
Wherein, the concrete numerical value that detects times N can be set according to the actual requirements.
Step 206～207, BS judges whether the testing result of a N continuous off-grid sense cycle T is 0 in the past, if, then judging this MS off-grid, BS discharges the resource that this MS and this MS take, and finishes current handling process; Otherwise, return step 201.
As the above analysis, this basic MS off-grid testing process is by long off-grid detection time (being a N continuous off-grid sense cycle T), make the quality of uplink signal of BS active detecting MS, can prevent that not only the resource on the BS from being hung for a long time, demand that also can compatible MS signal degradation, be the MS reservation of resource, can recover communication rapidly after the wireless signal of MS is improved.
Off-grid testing process when as shown in Figure 3, the MS request inserts may further comprise the steps:
Wherein, in the WiMAX system, it is Initial Ranging message that this request inserts message; This user ID is the MAC Address of MS.
Step 304～306, BS judges whether the testing result of a last off-grid sense cycle T that the already present MS that inserts with request in the network has a MS of same subscriber sign is 0, if be 0, then already present in the releasing network have the MS of this user ID and a resource that this MS takies, then change step 303 over to, otherwise; According to strategy, directly abandon the request access message of receiving or send response message and ask to be rejected with its access of notice MS to MS, this shows that MS asks access failure.
Immediate off-grid sense cycle when wherein, a described last off-grid sense cycle is meant with MS request access.
The concrete testing process of described off-grid sense cycle refers to that promptly step 201 is to step 204.
By above analysis as can be known, because default off-grid sense cycle T is shorter, thus the off-grid testing process when this MS request inserts can guarantee to break down and recover immediately as MS, during as power-off restarting, can allow this MS re-accessing network at once, thereby improve user's experience.
Be that example describes basic MS off-grid testing process in detail with the CINR that detects MS below, as shown in Figure 4, this flow process may further comprise the steps:
The specific implementation process of " in off-grid sense cycle T; BS detects the current CINR of MS " is: when off-grid sense cycle T begins, the CINR that BS just begins to detect MS is until off-grid sense cycle T end, and when off-grid sense cycle T finished, BS preserved the value of the current C INR of detected MS.
Step 402～204, BS judges the current CINR of MS whether less than default CINR detection threshold Th ', if the testing result of then putting current off-grid sense cycle T is 0, and deposits testing result in detection buffering area on the BS, then execution in step 405; Otherwise the testing result of putting current off-grid sense cycle T is 1, and deposits testing result on the BS detection buffering area, then returns step 401, promptly enters new off-grid sense cycle.
Step 406～407, BS judges whether the testing result of a N continuous off-grid sense cycle T is 0 in the past, if, then judging this MS off-grid, BS discharges the resource that this MS and this MS take, and finishes current handling process; Otherwise, return step 401.
If MS normally discharges in above-mentioned off-grid testing process, as MS shutdown etc., then no matter which step testing process marches to, and above-mentioned testing process can terminate.
Simply introduce the method for the CINR that detects MS below, this is a prior art.Before the method for introducing the CINR that detects MS, at first need to prove, when detecting the CINR of MS, correspondingly, off-grid sense cycle T should be set at and comprise the overtime duration that BS is the T27 timer that keeps of MS at least, guaranteeing that BS can receive the upstream data of MS, and be that MS distributes upstream bandwidth, thereby detect CINR for the upstream bandwidth of MS distribution.In actual applications, for the accuracy that improves detection and prevent flase drop, off-grid sense cycle T generally is made as the overtime duration that comprises three to four T27 timers.In addition, this T27 timer is not repeated them here by IEEEE802.16 agreement regulation.
As shown in Figure 5, the method for the CINR of this detection MS may further comprise the steps:
Wherein, the T27 timer can start after the Ranging process is finished.
Step 503～504 if BS receives the T27 overtime message, then show the upstream data of not receiving MS in this timing, so BS is MS assignment period ranging opportunity, so that MS sends upstream data; BS then can be MS distribution upstream bandwidth, then execution in step 507 afterwards.
Step 505～506 if BS receives the upstream data of MS, then need according to the active application of MS or the subscribed services quality of MS (QoS, Quality ofService), and BS is that MS distributes upstream bandwidth, and execution in step 507 afterwards.
Need to prove that though the foregoing description major part is that applied environment describes with the WiMAX communication system, the present invention is equally applicable to other wireless communication systems.
