Embodiment 1.
In conjunction with Fig. 1, a kind of concrete application of the present invention in the TD-SCDMA mobile communication mode is described.
Present embodiment is set: positioning equipment has been set up the sub-district on characteristic frequency, target terminal has resided on this characteristic frequency sub-district.Positioning equipment and target terminal have been set up man-to-man correspondence.
In order to reach purpose of the present invention, should be provided with and determine: the ascending pilot channel maximum transmit power of configuration target terminal, the number of times of ascending pilot channel maximum retransmit (maximum retransfers), the maximum transmission power of Random Access Channel.
The number of times of collocating uplink pilot channel maximum retransmit is called default pre-determined number again.
In addition, also counter to be set, when promptly working beginning, the state of counter be set.In the present embodiment, during the work beginning, counter clear " 0 ", after positioning equipment detects ascending pilot channel at every turn, counter is added " 1 ", when the counter accumulative total equals the pre-determined number numerical value of ascending pilot channel, send correct physical access channel.

When inserting at random, in order to improve the probability that the base station detects ascending pilot channel, target terminal all can send ascending pilot channel with bigger transmitting power usually.Therefore in the present invention, induce target terminal to send the method for ascending pilot channel continuously, be attainable in target side, and can not cause the abnormal behaviour of target terminal with maximum power.
According to the TD-SCDMA agreement, when inserting at random, the terminal parameters needed as the default pre-determined number of up pilot channel maximum transmission power, ascending pilot channel, Random Access Channel maximum transmission power etc., is all disposed by system message by network.Therefore, positioning equipment can be according to the configuration of expecting to target terminal transmitting system message on the basis of having caught target terminal.According to the TD-SCDMA agreement, when the maximum transmission power parameter surpassed the specified transmitting power of target terminal, target terminal will be with specified transmitting power emission.Therefore, when configuration maximum transmission power parameter, can be configured to surpass the numerical value of the specified transmitting power of terminal, like this, terminal can be with stable rated power emission wireless signal.
Positioning equipment triggers target terminal by the mode that sends paging.After having caught target, according to set paging parameters, configuration-system message, send to target terminal, make target terminal listening paging on the time slot of appointment and code channel.Then, positioning equipment sends effective paging indication and paging channel, triggers target and inserts at random.
In the process that inserts at random, target terminal at first sends ascending pilot channel.After positioning equipment is received ascending pilot channel, do not send physical access channel to target terminal; Its purpose all is in order to allow target terminal, not enter follow-up signaling process, thereby makes target terminal constantly send the ascending pilot channel signal, and positioning equipment is determined the accurate position of target terminal from a series of ascending pilot channel signal.
According to the TD-SCDMA agreement, in the WT subframe of target terminal after sending ascending pilot channel (WT≤4), if can not receive correct physical access channel affirmation, will random interval after a period of time, improve transmitting power and resend ascending pilot channel, this blanking time is generally very short.If positioning equipment continues not send physical access channel, target terminal will continue by the route shown in Fig. 1, gets back to target terminal and sends the link of ascending pilot channel, carries out follow-up flow process equally then.In this process, target terminal can send the ascending pilot channel of a series of intervals inequality, and the power of emission ascending pilot channel also can improve one by one, until for rated power, after positioning equipment is received a series of ascending pilot channel, calculate the distance and the direction of target terminal, promptly target terminal has been finished the location.Subsequently, positioning equipment sends physical access channel, and positioning equipment is received the Random Access Channel that target terminal sends.
In order to keep proper communication to target terminal, thereby maintenance trapped state, need the ascending pilot channel number of times that target terminal sends be added up, in case accumulating values equals pre-determined number, terminal positioning is not also finished, positioning equipment will send correct physical access channel to target terminal, and positioning equipment receives the Random Access Channel that is sent by target terminal then, makes the normal signaling process in back proceed, also discharge relevant connection.So just finished and once triggered and sought location process.
Can't finish location tasks if once seek location process, can repeat repeatedly to carry out above process, promptly enable counting device from positioning equipment again, in the present embodiment, be with counter clear " 0 ", carry out flow process shown in Figure 1 and position work again.
Embodiment 2
