Embodiment Construction

[0038] In the embodiment of the present invention, by introducing a dual-mode relay station with dual working modes of the terminal and the relay station and its corresponding network side control station into the wireless communication system, the relay function of the dual-mode relay station can be flexibly selected according to needs, and the dual-mode relay station can be realized. The remote control and path selection scheme of the working state of the relay station. When the dual-mode relay station provided in the embodiment of the present invention enters the network, it negotiates with its control station to determine whether to enter the network in terminal mode. If it is selected as the terminal mode to enter the network, after it enters the network, the relay function of the dual-mode relay station can be activated according to business and network needs. , converted to work in relay station mode. Both the dual-mode relay station and the control station can initiate...

Abstract

The invention discloses a double-mode relay station and a network access method, a mode conversion method and a control station thereof. While the double-mode relay station accesses the network, whether to access the network with a terminal mode is determined through negotiating with the control station thereof, if the terminal mode is selected for accessing the network, relay functions of the double-mode relay station can be started according to demands of business and the network after accessing, converting to a relay station operation mode. Both the double-mode relay station and the control station can request to start the relay functions of the double-mode relay station. In the mode conversion process, firstly, the relay station and a base station negotiate to start the relay functions of the double-mode relay station and negotiate a suitable path for starting the relay station; secondly, the double-mode relay station determines whether to set an operation mode of the double-mode relay station to be the relay station mode according to the negotiated results. The double-mode relay station and the network access method, the mode conversion method and the control station thereof realize flexible control to the relay station operation mode, especially having advantages in applications of non-fixed relay communication systems such as nomadic relay communication systems, mobile relay communication systems and so on.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-mode relay station and its network access method, mode conversion method and control station. Background technique [0002] In a wireless communication system, due to the path attenuation of electromagnetic waves, especially those using high-frequency carrier waves during transmission, and the shielding of electromagnetic wave transmission by buildings, the coverage of base stations (BaseStation, BS) is limited, making some The wireless communication signal strength in the areas is low, and the communication quality of a mobile station (Mobile Station, MS) serving as a terminal located in these areas will become very poor. Therefore, in order to solve the problem of small base station coverage caused by electromagnetic wave attenuation, the industry has begun to study the introduction of relay stations (Relay Station, RS) in wireless communication systems to...
