Description
Technical field
The present invention relates to the communications field, in particular to a kind of pilot beacon implementation method and device.
Background technology
In code division multiple access (Code Division Multiple Access abbreviates CDMA as) network, according to the demand of the network coverage, the frequency number of different site configuration may be different.As indoor covering website (indoor little station), capacity is less, and frequency of a general configuration just can satisfy the demands; And outdoor website covers (outdoor grand station) far away, and customer volume is bigger, all can dispose a plurality of frequencies, will dispose 4 frequencies as the cdma network of UNICOM.When travelling carriage is locked in outdoor f1 or f2 or f3 frequency, move one's steps when indoor from outdoor, no matter be conversation state or Idle state, can be by level and smooth being locked on the indoor f0 frequency of the pilot signal of indoor station f1 or f2 or f3 frequency, as shown in Figure 1, the pilot signal of f1 or f2 or f3 is also referred to as dummy pilot signal here.
Pilot beacon is extremely important for the unbalanced network type of this configuration of CDMA, and it can guarantee that mobile phone becomes soft handover by the original direct-cut operation that gets in the switching of using different carrier, thereby reduces the cutting off rate of mobile phone.
For example: travelling carriage uses carrier frequency f1 communication (talking state) under outdoor base station, when travelling carriage gradually away from outdoor base station, near indoor base station, indoor base station has only carrier frequency f0 that service is provided.The signal of the outdoor base station f1 that travelling carriage is received more and more a little less than, and the signal of indoor base station f0 strengthens gradually, can only adopt the mode of direct-cut operation to switch, and can produce 30 milliseconds interruption.Because the success rate of the alien frequencies direct-cut operation of different base station is very low, be very easy to form the phenomenon of call drop.In this case, indoor base station configuration dummy pilot signal.Under travelling carriage was in carrier frequency f1 service, when outdoor base station moved to indoor base station, the base station was with pilot signal strength frequently near travelling carriage can constantly detect.When the pilot signal parameter of the f1 at indoor station frequency surpassed threshold value, travelling carriage can initiatively send Pilot Strength Measurement Message (Pilot Strength Measuring Message abbreviates PSMM as) to the base station.After indoor base station is received message, inquire about the configuration information of this base station, find that the pilot signal of f1 frequency is actually dummy pilot signal, the possibility that the Traffic Channel of providing is not provided, have only the f0 frequency can the distribution service channel, therefore distribute the traffic channel resource of f0 frequency, realize switching for travelling carriage.Travelling carriage finished the switching from outdoor station f1 to indoor station f0, thereby the switching that guarantees is carried out smoothly under the pilot beacon of indoor station f1 frequency is assisted.Because this process belongs to soft handover, can call drop, thus improve success rate for switching.
Again for example: travelling carriage is in the carrier frequency f1 of outdoor base station standby (non-talking state, be holding state), when travelling carriage from outdoor shift to indoor when mobile, owing to having only the f0 carrier frequency, indoor website do not have the f1 carrier frequency, Mobile Origination rises when exhaling, because outdoor f1 is except pilot channel, the signal of other channels is very weak, can cause travelling carriage exhale the process transfer to go into outdoor Traffic Channel difficulty rising like this, cause call failure.In this case, indoor base station also needs to dispose dummy pilot signal.When travelling carriage from outdoor to indoor mobile process, detect the f1 signal with frequently, the f0 signal standby that switches to indoor station that can be level and smooth.This moment, recurrence was exhaled, and had just finished the flow process of exhaling under the various channels at indoor station again.
In correlation technique, base station equipment supplier adopts independent radio-frequency apparatus and the base band carrier frequency of a cover to launch one tunnel dummy pilot signal, and one road pilot beacon takies a base band carrier frequency, is configured to the carrier frequency of pilot beacon for needs, only dispose pilot channel, do not dispose other control channel.For example: certain sector is 1 common carrier frequency f0 of configuration down, disposes 3 pilot beacon f1, f2, and f3, the signal frequency point and the content of every road pilot beacon have nothing in common with each other, and radiation pattern is as shown in Figure 2.
But the contained fan number that the implementation of this pilot beacon can be supported the baseband modulation and demodulation chip has requirement, and promptly the baseband modulation and demodulation chip of system and radio system can be supported enough contained fan numbers.The chip supplier and the contained fan number that chip is supported places one's entire reliance upon.If the chip that chip supplier releases is only supported 2 contained fans, system for a plurality of pilot beacons of needs just can't realize that pilot beacon has disposed so, and the contained fan number that the baseband modulation and demodulation chip is supported is many more, and the cost of baseband modulation and demodulation chip is high more, has increased the equipment cost of operator.
