Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method, device and dual-mode base station equipment of realizing the dual-mode base station function.
Background technology
At present, mobile communication is more and more obvious towards the trend of broadband development, but along with the increasing of bandwidth demand, just needs the higher transmission band of exploitation and adopt the more modulation system of high-order.And on the one hand along with the increasing of frequency, the decay when signal is aloft propagated is just big more; On the other hand along with the increase of order of modulation, the needed signal to noise ratio of receiving terminal restituted signal is just high more, this will inevitably cause reducing of base station cell coverage, that is to say that will cover the needed base station number of area identical will increase, thereby brings the increase on the cost.
In actual implementation procedure, because the base station covering radius of radio communication is generally several kilometers in the urban district, and the speed of transfer of data can be along with successively decreasing with the increase of base station distance, when especially being in the base station and covering fringe region or regional that building blocks arranged, be illustrated in figure 1 as in the prior art communication scheme when being blocked by building, among the figure: the signal that base station BS sends is owing to exist blocking of building, make that quality of signals was relatively poor when signal was delivered to terminal MS, will cause telex network speed and communication quality all poor like this.In the prior art, for improving the coverage effect of mobile communications network, generally be to be undertaken by the mode that relay station (RS, Relay Station) or microcell base station (Micro cell) are installed.
