Description
Technical field
The present invention relates to Location Technology of Mobile Communication System, relate in particular to the repeater that has positioning function in the mobile communication system and report the method for detection and localization information.
Background technology
In existing mobile communications system, in order to solve covering problem, the repeater is adopted in a large number.Existing repeater mainly contains three types, is respectively that optical fiber repeater, RF direct amplifying station and radio frequency zoom out.No matter be which kind of repeater, all just play the function of signal forwarding.
Existing repeater can have a strong impact on the realization of mobile position estimation.Because the signal of repeater generally compiles at radio-frequency head, send the base station to handle then, so the base station is not distinguish the overlay area which repeater travelling carriage specifically is positioned at.When the overlay area of travelling carriage in the repeater, location survey will be introduced deviation, and existing repeater does not have corresponding detection and localization function and reporting functions, mobile positioning center can't be proofreaied and correct this deviation, therefore existing repeater can significantly reduce positioning accuracy, can cause the mobile location method of standard to lose efficacy when serious.As shown in Figure 1.What Fig. 1 showed is the schematic diagram of repeater to the location influence
Have the influence of repeater now to the mobile position estimation of different mobile communication system:
