Embodiment Construction

[0023] image 3 Shown is a network diagram of a repeater in a mobile communication system. Two forms of repeaters are shown in the figure, which are only a preferred embodiment. The present invention is also applicable to various networking modes such as frequency-selective repeater, frequency-shifting repeater and indoor repeater in other forms.

[0024] Such as image 3 As shown, the repeater picks up the downlink signal sent by the main base station through the donor antenna, and transmits it through the retransmission antenna to cover the coverage area of ​​repeater 1; the uplink signal in the coverage area of ​​repeater 1 is transmitted by the repeater After being received by the retransmission antenna of the station, it is transmitted by the donor antenna, and finally received by the main base station antenna. Similarly, the optical fiber repeater completes the signal transmission between the repeater and the main base station through the optical fiber, and the optica...

Abstract

The invention discloses a method and system for enhancing the mobile positioning service, which is applied to the communication system of the repeater, including: pre-storing the configuration information of network in the coverage areas of the main base-station and the repeater; extracting the information of adjacent area of the mobile station; matching the information of the adjacent area with the pre-stored configuration to identify the coverage area of the mobile station. The invention also discloses a controller of wireless network for enhancing the positioning service about the mobile station, which includes a store unit for storing the configuration information about network, extraction unit for extracting the information of adjacent area of the mobile station and a judging unit for judging the coverage area where the mobile stations locate by matching the information of the adjacent area with the pre-stored configuration.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication, in particular to the positioning technology under the repeater environment in the mobile communication system. 【Background technique】 [0002] With the development of the mobile communication industry, various new mobile value-added services and mobile data services are continuously launched, among which the LCS (LoCation Services, location service) service is generally optimistic and has received widespread attention. [0003] At present, there are three kinds of mobile positioning technologies widely used in 3G networks: network-based CELL-ID (Cell Identity, cell identification), OTDOA (Observed Time Difference Of Arrival, observed time difference of arrival) technology, A-GPS (Assisted Global Positioning Systems, network-assisted global positioning system) technology. Among them, OTDOA technology achieves positioning by measuring the relative arrival time of pilot signals of different ba...
