Description
Technical field
The present invention relates to the Radio Link monitoring technology, be meant the method and apparatus of a kind of reporting uplink link synchronization indication (In-sync)/step-out indication (Out-of-sync) especially, and wireless link monitoring method and device.
Background technology
In third generation partner program (3GPP, 3
RdGeneration Partnership Project) in the high-speed uplink packet access technique (HSUPA, High Speed Uplink Packet Access), adopts two kinds of transmission meanss, i.e. scheduled transmission mode and non-scheduled transmission mode.Simultaneously, in order to transmit uplink strengthening data, introduced ascending reinforced special channel (E-DCH, Enhanced DedicatedTransport Channel) and strengthen ascending control channel (E-UCCH, E-DCH Uplink ControlChannel), two kinds of channel multiplexings send on the uplink physical channel (E-PUCH, EnhancedUplink Physical Channel) that strengthens.In addition, also introduce E-DCH and inserted ascending control channel (E-RUCCH, E-DCH Random Access Uplink ControlChannel) at random.Subscriber equipment (UE) sends the scheduling of schedule information (SI, Scheduling Information) request resource by E-RUCCH when not having resource authorization and have data etc. to be sent; When resource authorization is arranged, can send SI information by the E-PUCH channel, so that assistant base station Node B carries out scheduling of resource.
For the scheduled transmission mode, UE needs termly to base station (Node B) SI reporting, and the base station is carried out resource authorization according to SI to UE.
So, UE is as described below by the fundamental mechanism that E-RUCCH sends SI:
When U E need to determine by use E-RUCCH SI reporting, UE uses E-RUCCH to send SI to Node B, and startup timer T-RUCCH and a counter, this counter is set to 1, judge the resource authorization information of before timer T-RUCCH is overtime, whether having received Node B then, if received resource authorization information, then stop timer T-RUCCH; Also do not receive resource authorization information if timer T-RUCCH is overtime, and Counter Value is not more than the N-RUCCH parameter, then can initiates the E-RUCCH process once more, and after sending SI, restart timer T-RUCCH, counter increase by 1 by E-RUCCH; Also do not receive resource authorization information if timer T-RUCCH is overtime, and this counter then stops timer T-RUCCH greater than the N-RUCCH parameter, and counter reset, process ends.
If Node B can not correctly receive the E-RUCCH data that UE sends always, then can not carry out resource authorization to this U E, this UE may be in the state that No Assets can be used for a long time, and UE may not send any upstream data for a long time yet, and is especially up when not having other type channels.At this moment, need network side the state of this UE to be judged and corresponding the processing that proper is exactly to judge by uplink synchronization state, and then trigger Radio Link Failure or wireless link recovery process.
In addition, the E-DCH transmission channel is to be mapped on the E-PUCH physical channel, has used the Adaptive Modulation and Coding technology, can select suitable code rate and modulation system, so that can mate with channel circumstance, obtains suitable single transmission error probability.Simultaneously, also adopted and mixed automatic request retransmission technology,,, improved the correct probability of decoding so that merge in the data of receiving terminal to repeatedly transmission if the single transmission mistake also may retransmit.Characteristics based on the E-DCH transmission, the E-DCH data will be very little through repeatedly transmitting the still wrong probability of merging, if E-DCH can not receive within the quite a long time correctly, then need the uplink synchronization state of UE is carried out corresponding judgment and processing, otherwise,, and do not carry out suitable processing if this UE can't recover uplink synchronous always, then can waste system resource, reduce systematic function.
Provide detection dedicated transmission channel (DCH in the present 3GPP TS25.224 agreement, Dedicated Transport Channel) and high-speed downlink shared transmission channel (HS-DSCH, HighSpeed Downlink Shared Channel) the coded combination transmission channel (CCTrCH of type, the method of synchronous regime Coded Composite Transport Channel), Node B is by the method for the synchronous regime of the CCTrCH of detection DCH type, whether monitoring up link that can be real-time is in synchronous regime, and triggers Radio Link Failure or wireless link recovery (RL failure/RL restored) process.At present, on the 3GPP agreement, do not provide concrete suggestion for the uplink synchronization state determination methods, just explanation can be according to the quality and the cyclic redundancy check (CRC) (CRC that receive data, Cyclic Redundancy Check) state is judged, and also can be with reference to descending synchronous regime determination methods.And for E-DCH, its transmission feature is different with DCH and HS-DSCH type channels, needs to provide on the standard corresponding synchronous state judging method and criterion, and the configuration that may need high-level signaling notice relevant parameter.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, lift specific embodiment below, the present invention is further detailed explanation.
The invention provides the method and the wireless link monitoring method of the synchronous/desynchronizing state indication of reporting uplink link, can after the state of uplink synchronisation/step-out is judged, handling accordingly.The present invention mainly provide the E-DCH Data Receiving that sends according to UE and decoding situation and UE upstream data detection case judge up link synchronously/desynchronizing state and the corresponding indication of report, and according to synchronously/method that step-out is indicated to determine the state of Radio Link and carried out subsequent treatment.
Figure 1 shows that the method flow diagram of judgement uplink synchronisation/desynchronizing state and reporting uplink link synchronization/step-out indication, realize by following steps:
Step 101: judge whether subscriber equipment (UE) disposes uplink special physical channel (DPCH), if user device configuration has up DPCH, then execution in step 102; If subscriber equipment does not have collocating uplink DPCH, then execution in step 103.
Step 102: the CCTrCH by judging the DCH type synchronously/desynchronizing state reports synchronously/step-out indicates.
For the CCTrCH of DCH type synchronously/the desynchronizing state determination methods can with reference to descending DPCH synchronously/the desynchronizing state determination methods, introduce no longer in detail at this.
Step 103: the CCTrCH by judging the E-DCH type synchronously/desynchronizing state reports synchronously/step-out indicates.
Below introduce in detail the CCTrCH that judges the E-DCH type synchronously/desynchronizing state reports synchronously/method that step-out is indicated, be specially: judge according to the following Rule of judgment that provides, and the synchronous or step-out indication according to the situation report that satisfies these Rule of judgment.
Rule of judgment one:
Comprise two kinds of implementations in the Rule of judgment one, can adopt any one mode.
First kind is, whether Node B judges data that continuous first stipulated number receives from UE for N time decoding error, if decoding error is then reported the step-out indication.At this, the data that receive from UE are specifically as follows the E-DCH data.
At this, the method to set up of the first stipulated number N is: the maximum transmission times of supposing each E-DCH data block is M, and then the first stipulated number N can get the value greater than M, for example can get the multiple of M.
Judge whether to satisfy first kind specific implementation method flow process as shown in Figure 2 of Rule of judgment one, this flow process may further comprise the steps:
Step 201: counter C1 is set, and is initialized as 0.
Step 202:Node B receives the E-DCH data that UE sends.
Step 203:Node B judges whether the E-DCH data that this UE sends are deciphered correctly, if decoding is correct, then execution in step 204, if decoding error, execution in step 205.
Step 204: counter is initialized as 0, returns step 202.
Step 205: counter C1 increases by 1.
Step 206:Node B judges whether counter C1 equals N, if equal N, then execution in step 207, otherwise return step 202.
The indication of step 207:Node B report step-out.
Whether all second kind is, judge in the first stipulated time T data that receive from UE decoding error, if decoding errors is all then reported the step-out indication.At this, the data that receive from UE are specifically as follows the E-DCH data.
At this, the method to set up of the first stipulated time T is: T＞=N * delta
Wherein, delta represents that UE sends the average time interval of E-DCH data, and first set in N and the above-mentioned first kind of mode stipulated number value is identical.
Judge whether to satisfy second kind specific implementation method flow process as shown in Figure 3 of Rule of judgment one, this flow process may further comprise the steps:
Step 300: timer T1 is set, and the cycle of this timer T1 is T.
Step 301: T1 is initialized as 0 with timer, and starts this timer T1.
Step 302:Node B receives the E-DCH data that UE sends.
Step 303:Node B judges whether these E-DCH data are deciphered correctly, if decoding is correct, then returns step 301; If decoding error, then execution in step 304.
Step 304: timer T1 continues timing.
Step 305:Node B judges whether timer T1 is overtime, if overtime, then execution in step 306; Otherwise, return step 302.
The indication of step 306:Node B report step-out.
Based on Rule of judgment one, if all can not correctly receive the E-DCH data that UE sends within long a period of time in regulation, can think that then the up link of this UE has been in desynchronizing state and handles accordingly, make this UE recover uplink synchronous as early as possible, avoid resource waste, thereby improve systematic function.
Rule of judgment two:
Node B judges whether detect the upstream data of UE in the second stipulated time T-Out-of-Sync, if do not detect any upstream data, then reports the step-out indication.At this, any upstream data is meant the data of sending by any up channel.
At this, the method to set up of the second stipulated time T-Out-of-Sync is: T-Out-of-Sync is set to much larger than sending N-RUCCH needed time of E-RUCCH data, that is: T-Out-of-Sync＞＞N-RUCCH * T '.
Wherein, N-RUCCH represents that UE sends the maximum times of E-RUCCH data continuously, is a parameter of high-level signaling configuration; The time interval of twice E-RUCCH process is initiated in T ' expression continuously.
Based on Rule of judgment two, Node B does not detect report step-out indication under the situation of any upstream data of U E in the second stipulated time T-Out-of-Sync, can think that then the up link of this UE has been in desynchronizing state, and handle the Radio Link Failure process that triggers accordingly, avoid resource waste like this, thereby improve systematic function.
Go on to say the technique effect that Rule of judgment two is brought below in conjunction with following three scenes.
Scene a: when UE does not wait data to be sent for a long time, when promptly total E-DCH buffer status (TEBS:Total E-DCH Buffer Status) was zero, UE can be to Node B transmission upstream data for a long time in.But in case TEBS becomes greater than zero, and UE do not have resource authorization to use, and then UE can initiate the E-RUCCH transmission to Node B, thereby obtains uplink synchronous information.
The TEBS of scene b:UE is greater than zero, and UE still incorrect reception of Node B after the number of times that Node B sends the E-RUCCH data continuously arrives maximum times, then Node B can not carry out scheduling of resource for this UE because correctly receiving the E-RUCCH data that U E sends, and UE is owing to the resource authorization that does not receive Node B, so UE can not send upstream data to Node B.
The TEBS of scene c:UE is greater than zero, and UE sends the E-RUCCH data and Node B correctly receives to Node B, but Node B just can carry out resource authorization after between very long one section.
Rule of judgment two traded off scene a, b, three kinds of situations of c promptly, guarantee report step-out indication under scene b, make network side trigger the Radio Link Failure process after the up link step-out; And under scene a and scene b, can frequently not report the step-out indication, and reduce the unnecessary operations such as Radio Link deletion that cause by triggering the Radio Link Failure process, improved user experience.
Judge whether to satisfy the specific implementation method flow process as shown in Figure 4 of Rule of judgment two, this flow process may further comprise the steps:
Step 400: timer T2 is set, and the cycle of this timer T2 is T-Out-of-sync.
Step 401: T2 is initialized as 0 with this timer, and starts timer T2.
Step 402:Node B detects whether the upstream data of UE is arranged, if detect, then returns step 401, if do not detect, then execution in step 403.
Step 403: timer T2 continues timing.
Step 404:Node B judges whether timer T2 is overtime, if overtime, then execution in step 405, otherwise, return step 402.
The indication of step 405:Node B report step-out.
Rule of judgment three:
Node B judges whether to receive the E-DCH data that UE sends and judges whether these E-DCH data are deciphered correctly, if it is correct to receive E-DCH data and decoding that UE sends, then report is indicated synchronously.
According to Rule of judgment three, E-DCH data and decoding that Node B receives the UE transmission at every turn are correct, then report a subsynchronous indication, thereby reflect the situation of uplink synchronisation in real time.
Rule of judgment four:
Judge whether to receive the E-RUCCH data that UE sends and judge whether these E-RUCCH data are deciphered correctly, if it is correct to receive E-RUCCH data and decoding that UE sends, then report is indicated synchronously.
According to Rule of judgment four, E-RUCCH data and decoding that Node B receives the UE transmission at every turn are correct, then report a subsynchronous indication, thereby reflect the situation of uplink synchronisation in real time.
Judge the E-DCH type CCTrCH synchronously/desynchronizing state reports synchronously/during method that step-out is indicated, as first embodiment, can judge simultaneously whether the CCTrCH of E-DCH type meets the condition of above-mentioned Rule of judgment one, Rule of judgment two and Rule of judgment three, and report meets the indication of corresponding Rule of judgment.Perhaps,, can judge simultaneously also whether the CCTrCH of E-DCH type meets the condition of above-mentioned Rule of judgment one, Rule of judgment two, Rule of judgment three and Rule of judgment four, and report meets the indication of corresponding Rule of judgment as second embodiment.
Provide below according to above-mentioned synchronously/the step-out order report determines synchronous/desynchronizing state of Radio Link, thereby trigger the wireless link monitoring method of Radio Link Failure/recovery process, be specially: obtain synchronously/the step-out order report, and according to obtained synchronously/step-out indication determine Radio Link synchronously/whether desynchronizing state change, if determine that Radio Link is changed to desynchronizing state from synchronous regime, then trigger the Radio Link Failure process; If determine that Radio Link is changed to synchronous regime from desynchronizing state, then trigger the wireless link recovery process.
Figure 5 shows that Radio Link observation process schematic diagram.When CCTrCH is in synchronous regime, enter step 501, determine whether CCTrCH is changed to desynchronizing state.
Step 500:Node B receives step-out indication and indication synchronously.
Step 501:Node B receives N continuous _ OUTSYNC_IND step-out indication.
Step 502:, and start this timer T_RLFAILURE with timer T_RLFAILURE initialization.
Step 503:Node B judges whether received N continuous _ INSYNC_IND indication synchronously before timer T_RLFAILURE is overtime, if then return step 505; Otherwise, execution in step 504.
Step 504:Node B determines that the state that the state of this CCTrCH becomes desynchronizing state and this CCTrCH is set to desynchronizing state.At this moment, Node B indicates this CCTrCH to be in desynchronizing state by desynchronizing state primitive to high level, triggers the Radio Link Failure process.Return step 500.
Step 505:Node B determines that the state that the state of this CCTrCH becomes synchronous regime and this CCTrCH is set to synchronous regime.At this moment, Node B indicates this CCTrCH to establish again synchronously by synchronous regime primitive to high level, triggers the wireless link recovery process.Return step 500.
Come the state of monitoring wireless circuit and trigger Radio Link Failure/recovery process by above step repeatedly.
In the Radio Link observation process shown in Figure 5, the Radio Link Failure process is to be triggered by network side.The present invention gives a kind of method that is triggered the Radio Link Failure process by UE, be specially: UE judges whether to receive resource authorization information after sending the E-RUCCH data, if after the continuous transmission second stipulated number N-RUCCH subtracts E-RUCCH data, do not receive resource authorization information yet, then after the N-RUCCH time sends the E-RUCCH data, wait for the 3rd stipulated time T-temp, and judge in the 3rd stipulated time T-temp, whether to receive resource authorization information, if do not receive resource authorization information, then UE triggers the Radio Link Failure process.Wherein, the second stipulated number N-RUCCH is the maximum times that sends the E-RUCCH data continuously.The method to set up of the 3rd stipulated time T-temp is: the 3rd stipulated time T-temp can be arranged to the identical value with the 4th stipulated time T-RUCCH, perhaps bigger than this T-RUCCH value.T-RUCCH is that UE transmission E-RUCCH data begin to initiating the time interval between the E-RUCCH process next time.T-RUCCH is disposed by high-level signaling.The acquisition methods of the 3rd stipulated time T-temp is: by the high-level signaling configuration, perhaps the value according to the 4th stipulated time T-RUCCH calculates.Therefore under above-mentioned scene b, UE also can trigger the Radio Link Failure process, thereby can be handled accordingly as early as possible after the up link step-out.
