Embodiment Construction
[0024] The present invention is used in mobile communication systems such as figure 1 As shown, some base stations 221, 222, . Within these coverage areas, services are provided by mobile communications. But in some other areas 231, 232, ..., 23m, which cannot be covered by normal base stations. Using the relay equipment 241, 242, ..., 24k of the present invention, the antenna of the terminal access unit of the relay equipment is set up in the area covered by the normal base station 221, 222, ..., 22n; and the antenna of the base station functional unit covers the area covered by the normal base station Areas that cannot be covered form a subnetwork. The working mode of the user terminal in the coverage area of the sub-network is exactly the same as that in the coverage area of the normal base station. It can be seen that the relay equipment expands and improves the coverage of the mobile communication network. Since the relay device can be installed on a mobile body, ...

The communication system belongs to the time division and the frequency division mobile communication system area. The relay communication apparatus include the terminal switch in function unit, the independent antenna and feed line, the radio frequency receiver and transmitter, the signal process device in physical layer, the master control unit, the digital signal processor etc. The mobile communication system using the relay communication apparatus includes at least one side device. The invented device can arranged the antenna and feed line in function part of the base station on the area,where the mobile communication network does not cover on, making the users on the said area obtain the services. The invention can provide the services quickly so as to improve the covering situation, making the users in trains, long-distance buses, in building also obtain the services.
Description
technical field [0001] The present invention relates to a relay communication technology for a mobile communication system, in particular to a relay communication device for a mobile communication system, a communication method thereof and a mobile communication system using the device, belonging to time division duplex or frequency division duplex field of mobile communication systems. Background technique [0002] In the third generation mobile communication system, typical equipment includes core network, base station controller (or called wireless network manager), wireless base station and user terminal and so on. In a time-division duplex (such as TD-SCDMA system) or frequency-division duplex mobile communication system, a device that not only functions as a user terminal but also functions as a wireless base station is called a relay device. Relay equipment is particularly important in the following environments: areas where it is difficult to install optical cables ...
