Multi-mode base station wireless system

Abstract

The present invention provides a multi-mode base station wireless system, the system mainly includes: multi-mode wireless transfer base station: used for accessing wireless users of various modes, performing local exchange for signals of wireless users of various modes in the same cell, and passing through wireless channels Or transmit wireless user signals or cell switching data between wired and cable and multi-mode wireless base stations in active / standby mode or load sharing mode, and support direct cell switching between multi-mode wireless base stations, that is, the source multi-mode wireless base station passes through wireless channels or wired lines The handover data transmitted by the cable is bypassed and directly transmitted to the destination multi-mode wireless base station without the handover processing of the multi-mode wireless transfer base station; multi-mode wireless base station: used to access wireless users of various modes, Mode wireless user signals are switched locally, and wireless user signals or cell switching data are transmitted between the multi-mode wireless transfer base station in active / standby mode or load sharing mode through wireless channels or wired cables. Utilizing the present invention, the base station Mesh (mesh) network can be formed between the multi-mode wireless base station and the multi-mode wireless transfer base station, thereby improving the system capacity, and performing fast cell switching between the base stations, thereby shortening the cell switching time delay.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a multi-mode base station wireless system. Background technique [0002] In the planning and deployment phase of a large-scale wireless network, network costs mainly include network element costs and base station site costs. The cost of network elements is mainly related to the cost of electronic components; the cost of a base station site is mainly related to the acquisition and operation of the site, such as base station backhaul costs, land lease fees for station towers, etc. With the gradual decline in the cost of electronic components, the cost of base station sites has become the main cost of large-scale wireless networks. [0003] Existing large-scale wireless networks are usually single-mode wireless systems. Its system structure is like figure 1 As shown, it consists of a wireless base station and a wireless base station controller. The wireless base station and the wire...

Problems solved by technology

[0007] 3. When a cell handover occurs, the handover data of the source base station must be forwarded to the wired transmission processing unit of the base station controller through a wired cable, and then forwarded to the destination multi-mode wireless base station after being processed by the handover processing unit. Therefore, it will cause Large switching delay
