In addition, subscriber equipment 200 comprises detection module 230 and correcting module 240.Detection module 230 is sent to subscriber equipment 200 to adjust the sequencing control order of the up transmission timing of subscriber equipment 200 in order to base stations detected 201, decides this sequencing control order and whether meets aberrant commands condition.Correcting module 240, in order to when this aberrant commands condition meets, is revised this sequencing control order that base station 201 sends, and is decided the up transmission timing of subscriber equipment 200 according to this sequencing control order revised.
Please refer to Fig. 3, Fig. 3 is detection and the modification method flow chart of sequencing control order according to an embodiment of the invention, and the method can perform by subscriber equipment 200 as shown in Figure 2, and the step wherein shown in Fig. 3 is as follows:
Step 302: check that base station is sent to subscriber equipment and whether meets aberrant commands condition with the sequencing control order of the up transmission timing adjusting this subscriber equipment.
Step 304: revise the sequencing control order that this base station sends, and decide the up transmission timing of this subscriber equipment according to revised sequencing control order.
For example, adopt Time Division-Synchronous Code Division Multiple Access between subscriber equipment 200 and base station 201, in addition, above-mentioned sequencing control order can be simultaneous bias order.The present invention does not limit step 302 and ad hoc approach must be used to check whether sequencing control order meets aberrant commands condition, does not limit the sequencing control order that step 304 must use ad hoc approach to send to revise base station yet.In order to contribute to the flow process understanding subscriber equipment 200, the present invention enumerates following multiple embodiment, but those embodiments only illustrative object, not as restriction of the present invention.
Please refer to Fig. 4, Fig. 4 is detection and the modification method flow chart of sequencing control order according to an embodiment of the invention, and wherein Fig. 4 can be considered the change case done based on the flow process shown in Fig. 3, and step is as follows:
Whether step 402: the quantity and the threshold value that compare sequencing control order, decide aberrant commands condition and meet.
Step 404: when this aberrant commands condition meets, it is abnormal that subscriber equipment judges that the sequential control command received from base station occurs.
Step 406: revise the sequencing control order received at present according to the current translational speed of subscriber equipment or maximum translational speed.

Please refer to Fig. 6, Fig. 6 is detection and the modification method flow chart of sequencing control order according to an embodiment of the invention, and wherein Fig. 6 can be considered the change case done based on the flow process shown in Fig. 3, and step is as follows:
Whether step 602: the quantity and the threshold value that compare sequencing control order, decide aberrant commands condition and meet.
Step 604: when this aberrant commands condition meets, it is abnormal that subscriber equipment judges that the sequential control command received from base station occurs.
Step 606: revise the sequencing control order received at present according to the descending timing variations amount of subscriber equipment.
Step 608: the up transmission timing deciding subscriber equipment according to revised sequencing control order.

Please refer to Fig. 7, Fig. 7 is detection and the modification method flow chart of sequencing control order according to an embodiment of the invention, and wherein Fig. 7 can be considered another change case done based on the flow process shown in Fig. 3, and step is as follows:
Step 702: judge the up transmission timing whether only adjusting subscriber equipment within a scheduled time from multiple sequencing control orders of base station gradually single direction, decide aberrant commands condition and whether meet.
Step 704: when this aberrant commands condition meets, it is abnormal that subscriber equipment judges that the sequential control command received from base station occurs.
Step 706: revise the sequencing control order received at present according to the descending timing variations amount of subscriber equipment.
Step 708: the up transmission timing deciding subscriber equipment according to revised sequencing control order.
Fig. 7 have employed the 4th kind of method detecting aberrant commands condition and whether meet, shown in method shown in Fig. 7 and Fig. 5, the difference of method is, step 706 considers the descending timing variations amount of subscriber equipment 200, estimate the up transmitting time lead of required adjustment, to revise the sequencing control order received at present, similar in appearance to previous embodiment, one of reason is that the descending sequential of subscriber equipment 200 can correspondingly change when sequential control command occurs abnormal.
Please refer to Fig. 8, Fig. 8 is detection and the modification method flow chart of sequencing control order according to an embodiment of the invention, and wherein Fig. 8 can be considered another change case done based on the flow process shown in Fig. 3, and step is as follows:
Step 802: whether have another subscriber equipment that uplink transmission power is greater than the uplink transmission power of this subscriber equipment near detecting subscriber equipment, decide aberrant commands condition and whether meet.
Step 804: when aberrant commands condition meets, it is abnormal that subscriber equipment judges that the sequential control command received from base station occurs.
Step 806: the uplink transmission power heightening subscriber equipment, revises to impel base station this sequencing control order sent next time.
Step 808: the up transmission timing deciding subscriber equipment according to revised sequencing control order.
The method whether Fig. 8 adopts the 5th kind to detect aberrant commands condition and meet, in step 802, whether detection module 230 can by having another subscriber equipment that uplink transmission power is greater than the uplink transmission power of subscriber equipment 200 near detecting subscriber equipment 200, decide this aberrant commands condition whether to meet, because when this another subscriber equipment has too large uplink transmission power, may cover or have influence on the up running of subscriber equipment 200 itself, in other words, the synchronous control command that the requirement that subscriber equipment 200 is passed in base station 201 adjusts up transmitting time may be based on this larger another subscriber equipment of uplink transmission power, but not based on subscriber equipment 200, therefore synchronous control command just can carry out mistake adjustment to the up transmission timing of subscriber equipment 200.
Then can heighten the uplink transmission power of subscriber equipment 200 in step 806, the sequential control command sent next time is revised to impel base station 201, wherein preferably the practice is that the uplink transmission power of subscriber equipment 200 is adjusted to the uplink transmission power being greater than this another subscriber equipment, but the present invention is not as limit.
In an execution mode, the step heightening the uplink transmission power of subscriber equipment 200 realizes by the uplink open-loop power control (Uplink Open-Loop Power Control, U-OLPC) enabling subscriber equipment 200.In general, closed-loop power control (closed loop power control) refers to the process that transmitting terminal controls transmitting power according to the feedback information that receiving terminal is sent here.Be different from closed-loop power control, open loop power control does not then need the feedback of receiving terminal, and the information that transmitting terminal (that is carrying out the subscriber equipment 200 of up transmission) measures according to self controls transmitting power.In addition, uplink open-loop power control constantly can compare the signal to noise ratio (Signal-to-Noise Ratio, SNR) between subscriber equipment 200 and base station 201, when signal to noise ratio is lower than demand, just heightens the ascending power of subscriber equipment 200; In addition, when signal to noise ratio is higher than demand, the ascending power of subscriber equipment 200 can also be turned down to carry out power saving.
The multiple change case that Fig. 3 step 302,304 is done is listed in the embodiment of Fig. 4 ~ Fig. 8, wherein correction base station 201 is sent to subscriber equipment 200 and separately or can mixes use with the multiple method (such as step 406, step 606 or step 506, step 706) adjusting the sequencing control order of the up transmission timing of subscriber equipment 200, such as, while considering the current translational speed of subscriber equipment 200 or maximum translational speed, heighten the uplink transmission power of subscriber equipment 200 in the lump, revise the sequencing control order received at present; Or while the descending timing variations amount of such as consideration subscriber equipment 200, heighten the uplink transmission power of subscriber equipment 200 in the lump, revise the sequencing control order received at present.
In sum, whether subscriber equipment of the present invention base stations detected sends voluntarily sequencing control order can there is exception, when detecting abnormal sequencing control order, the sequencing control order that subscriber equipment meeting active correction base station of the present invention sends, and decide up transmission timing according to revised sequencing control order, therefore, when subscriber equipment performs uplink synchronous, the up transmission timing of subscriber equipment just can be improved by the situation adjusted mistakenly.
