Technical field
The present invention relates to the mobile communication application field, relate in particular to a kind of system of cell signals coverage in mobile communication.
Background technology
Cell mobile communication systems comprise with mobile control station (Mobile Control Station, MCS) a plurality of base stations of long-range connection (Base Station, BS).In down link, the signal of base station source generates CF signal, is used to launch the information from MCS, the sub-district under covering with this.In the cellular cell of reality or by the sub-district, usually exist two kinds of special tiny areas: the one, the blind area, owing to electric wave runs into the shadow region that barrier causes in communication process, this area communication quality is seriously inferior, and the blind area is all or part of cell edge that exceeds of possibility also; The 2nd, hot-zone, the heavy traffic zone that the uneven distribution of loading owing to space service forms.Therefore specialized apparatus coverage hole and hot-zone need be set, relatively, macro base station coverage area is called the primary area, and the zone that equipment covered that is specifically designed to coverage hole or hot-zone is called from the district.
In order to solve above-mentioned covering problem from the district, traditional scheme has following two kinds:
In the cell mobile communication systems, at the network operation initial stage, the main target of operator is to build large-scale cellular cell, obtains big as far as possible ground domain coverage ratio.The radius of each cellular cell is bigger, about 1km～25km, so be called " macrocellular ", corresponding base station is called " macro base station ".There are blind area and hot-zone in the macro cells inevitably, by adopting special described blind area and the hot-zone of covering, the lower base station of through-put power, the radius of this cellular cell is less, about 30m～300m, be commonly referred to " microcellulor ", corresponding base station is called " little base station ".Macro base station is distinguished the long-range mobile control station that is connected with little base station, uses different frequency ranges, in order to avoid in the primary area and from area overlapping the channel interference takes place.
Between mobile control station and little base station, adopt wireless connections, often with a varied topography or large amount of building is arranged near described blind area or the hot-zone after little base station is located near blind area or the hot-zone, can influence communicating by letter between mobile control station and the little base station.After wired connection between mobile control station and the little base station, but, need to lay long circuit for little base station being caused the place of coverage hole or hot-zone; Often with a varied topography or large amount of building is arranged near blind area and the hot-zone, increased the especially cost of optical fibre installation of track laying.
Can draw little Cell Site Placement thus and be subjected to usually limitting, can't take into account signal quality and construction cost from zone position.
Described from the district also can by be provided with the repeater cover described from the district, but the repeater is arranged on the place of coverage hole or hot-zone, as the co-channel extension of base station, primary area.The construction cost of repeater is lower than microcell base station, but uses same channel from the repeater in district and the base station in primary area, in the primary area and from area overlapping interference between the channel signals will take place inevitably.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the invention provides a kind of system of cell signals coverage in mobile communication, guaranteed signal of communication quality and communication construction cost by described system.
In order to solve the problems of the technologies described above, the embodiment of the invention has proposed a kind of system of cell signals coverage in mobile communication, described system comprises the mobile base station of the mobile control station of long-range connection, described mobile base station is used to cover the primary area signal, described system also comprises at least one repeater and at least one mobile terminal, described repeater is used to provide with the different channel signals in mobile base station and covers the signal from the district, and described terminal connects mobile control station and provides required CF signal to described repeater.
Described repeater is a frequency-shift repeater, the required CF signal in repeater that the channel signals of described repeater uses the microcellulor signal source to generate by mobile terminal, all sub-districts covered described channel signals from the district around the channel signals that use described repeater was different from.
Described mobile terminal moves control station by wired connection, and described wired connection is that optical fiber connects.
Describedly be blind area or hot-zone in the primary area from the district.
By implementing the embodiment of the invention, in the sub-district, the mobile base station is set and match in the repeater, avoided the appearance of co-channel interference phenomenon, guaranteed the communication quality of whole sub-district.

Fig. 1 is the system diagram of cell signals coverage in mobile communication in the embodiment of the invention.
Embodiment
The embodiment of the invention is by providing a kind of system of cell signals coverage in mobile communication, and the appearance of co-channel interference phenomenon has been avoided in the repeater of using different frequency range in distinguish in same sub-district, has guaranteed the communication quality of whole sub-district.
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 shows the system schematic of cell signals coverage in mobile communication in the embodiment of the invention, comprises MCS, base station, terminal and repeater.Wherein, MCS is used for sending information to base station and terminal, the base station is used to cover the signal in the scope of primary area, in the scope of primary area some can not cover signal from the district, as hot-zone or blind area, when perhaps edge's jitter or communication quality are very poor between two sub-districts, need cover by the CF signal of repeater.Described repeater be arranged in blind area or the hot-zone or they near, provide CF signal to the repeater by terminal, the repeater covers described blind area or hot-zone by described CF signal, the repeater also receives the signal of travelling carriage in hot-zone since then or the blind area scope, and the signal that receives is sent back to terminal.
The near-end of described repeater is located at the terminal place, directly receive and dispatch the signal of terminal, far-end be located in blind area or the hot-zone or they near be used to cover described signal from the district, use and the different channel signals in base station, primary area in district's scope described described repeater.It is good that frequency-shift repeater is adopted in described repeater, because frequency-shift repeater has high-isolation wireless connections characteristic, can better solve the signal transmission difficulty that causes because of the landform fault, and the use by the repeater, circuit is laid to that this is also very low in the process of mobile communication construction.After the input of repeater, the repeater not necessarily is in the blind area of the central area in primary area, it many times is the edge that is in a plurality of sub-districts, the zone of the jitter that the edge of these sub-districts causes after can existing blind area that some all base stations all do not cover or a plurality of base station to cover, when these zones are provided with the repeater, need to consider the channel signals of peripheral a plurality of base stations, the channel signals that use described repeater is all different with the channel signals of the cell base station of this described periphery, to avoid the interference between the channel signals.
Described terminal is arranged in the suitable distance in place, repeater, do not need to be separated by too far away with the distance of repeater, the CF signal that terminal generates can reach interior the getting final product of distance range of repeater, the CF signal that terminal generates reaches the repeater and also should satisfy and need not the macrocellular signal source that adopts power bigger, because the construction cost in the wasting of resources that the use of macrocellular can cause and the increasing communication engineering, so terminal should use the microcellulor signal source directly to generate the required CF signal in repeater, reduce the communication construction cost.If what adopted the repeater is frequency-shift repeater, low because the near-end machine of frequency-shift repeater is arranged on the terminal place to the signal source requirement that described terminal produces, be convenient to select small-sized communication equipment cheaply as terminal.What adopt between described terminal and the MSC is wired connection, because between terminal and the MSC all is remote communication, have only the stability and the reliability that could guarantee whole transmission course by wired connection, described transmission line generally adopts Optical Fiber Transmission or cable transmission etc.
In sum, to cover the repeater residing from the district by using terminal to generate to be sent to the place, repeater with the different channel signals in base station, primary area, guaranteed from the communication quality of district's scope, by using repeater and small-sized terminal to make communication construction convenient, also reduced the construction cost of whole communication engineering.
Above disclosed only is preferred embodiment in the embodiment of the invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of doing according to claim of the present invention still belongs to the scope that the present invention is contained.
