Problems solved by technology

[0005] Although the centralized base station system based on remote antenna units has the advantage of resource sharing, in order to give full play to the benefits of centralized channel processing resources, it is often necessary to control as many cells as possible, which will also cause the following problems: one problem is The cost of the transmission link increases, because the geographically distant cells need to be connected to the central channel processing subsystem through broadband links such as optical fibers, thereby increasing the cost of the transmission link; another problem is the reliability of the system Decrease, because once the central channel processing subsystem fails, a large number of cells will not be able to provide services. Although increasing the resource redundancy of the central channel processing subsystem can reduce the impact of this unfavorable factor to a certain extent, this in turn offsets The centralized base station system based on remote antenna units has the advantages of lower cost due to resource sharing

[0022] 1. System structure

[0023] Fig. 3 shows an embodiment of the distributed wireless system based on the centralized control of channel processing resources of the present invention. As shown in FIG. 3 , a distributed wireless system 20 based on centralized control of channel processing resources includes a radio control and routing gateway 22 , a radio gateway (Radio Gateway-RG) 23 and a remote antenna unit (RAU) 24 . The wireless gateway 23 completes the processing of the uplink and downlink wireless signals, which is similar to the processing of the channel processing unit of the centralized base station system. The wireless gateway 23 is connected to a remote antenna unit (RAU) 24 via an interface Ira. The distributed radio system 20 comprises a plurality of radio gateways 23, between which an interface Irg is established. Each wireless gateway 23 is connected to a radio control and routing gateway (Radio Control and Routing Gateway-RCRG) 22 through an interface Ir...

[0040] Most of the second embodiment of the present invention is similar to the first embodiment, so the following description omits the same parts, and only the differences will be described in detail.

[0041] 1. System structure

[0042] Fig. 4 shows another embodiment of the distributed wireless system based on centralized control of channel processing resources of the present invention. Figure 4 provides an interface with the BSC / RNC where the user plane data flow and control flow are separated. The difference with the first embodiment of Fig. 3 is that the radio control and routing gateways are replaced by radio gateway controllers (Radio Gateway Controller-RGC) 32; each radio gateway 33 directly provides BSC / RNC 31 through the Ir-u interface The user plane data flow is transmitted, and each wireless gateway 33 is connected to the wireless gateway controller 32 through an Ir-c interface, and the wireless control gateway 32 provides a control plane interface to connect t...

Abstract

A distributed system is disclosed, which controls the resource centrally. The system comprises: a plurality of communication processing device connected with each other, each of which processes the channels within its own cell, such as converting the uplink radio signals finto the uplink data frames and converting the downlink data frames into the downlink radio signals; system control device, which is connected with the said communication devices and network control device and comprises a channel process and deploy means, for controlling the allocation of intermediate channel processing tasks to the said communication processing devices, so as to allocate the channel process tasks within a cell that one communication processing device is in charge to another channel processing device; and routing means, for routing and delivering data between the network control device and wireless gateway.

Description

technical field [0001] The invention relates to the wireless access network field of a mobile communication system, in particular to a distributed wireless system with centralized control of channel processing resources. Background technique [0002] In a mobile communication system, a base station (BTS) completes the transmission, reception, and processing of wireless signals. A traditional BTS is mainly composed of a baseband processing subsystem, a radio frequency (RF) subsystem, and an antenna. A BTS can cover different areas through multiple antennas. A cell is shown in Figure 1a, and each BTS is connected to a Base Station Controller (BSC) or a Radio Network Controller (RNC) through a certain interface, as shown in Figure 1b. [0003] In the traditional base station system shown in Figure 1a, since the corresponding baseband processing subsystems, RF subsystems and antennas of each cell are geographically concentrated together, each cell must be configured with a suffi...
