Problems solved by technology

[0006] To sum up, the disadvantages of the existing technology are: due to the backup of configuration resources of the faulty PPCs in the active / standby mode, each PPC in the WiMAX base station system cannot share the configuration resources in the CSIB data configuration module. Therefore, when the PPC When a fault occurs, the configuration resources can only be manually modified by the system maintenance personnel, and the RRU connected to the faulty PPC is manually connected to the normal working PPC
During the period when the system maintenance personnel manually modify the configuration resources, the RRU cannot work normally, which will lead to a long-term interruption of the provision of end-user data services in the RRU coverage area

Embodiment 1

[0059] For the situation that the WiMAX split base station system includes 6 PPCs, and one RRU is attached to one PPC. Here, the threshold value N of the PPC is 3, that is to say, a PPC can access up to 3 RRUs. The serial numbers of the PPCs in the system are: PPC[1]~PPC[6], and the capabilities of PPC[1]~PPC[6] to access the RRU are the same. The PPC and the RRU are connected through the IQ switching logic through the CSIB according to the sequence numbers corresponding to the PPC and the RRU. For example, PPC[1] is connected to RRU[1]. Moreover, PPC[1] has an abnormality during operation, but the RRU[1] connected to it can still work normally.

[0060] The method flow in this embodiment includes the following steps:

[0061] Step 201, after the CSIB is normally powered on, the control configuration module first obtains the static configuration relationship between the PPC and the RRU in the configuration resources of the data configuration module.

[0062] Step 202 , acc...

Abstract

The invention discloses a share and back-up method for base band configuration resources in a WiMAX base system. The method comprises the steps of the share control of all base band physical layer processing boards (PPC) and configuration resource in an exchange interface board (CSIB) data configuration module in the system; detection of PPC working state; and dynamic configuration of the configuration resources according to the normal or abnormal working state of PPC. The method of the invention can realize share back-up of configuration resource and the dynamic configuration function; a remote radio unit (RRU) connected with a fault PPC can be connected to a PPC in normal work state and provided with a surplus processing interface so as to minimize the influence on terminal a terminal user data service in coverage area of RRU which breaks down because of PPC failure; when the base station is unattended and a failure occurs to the PPC, the base station has quick self-restorability.

Description

technical field [0001] The invention relates to resource sharing and backup technology, in particular to a method for sharing and backing up baseband configuration resources in a Worldwide Interoperability for Microwave Access (WiMAX) base station system. Background technique [0002] The WiMAX base station system is a split base station system. The baseband unit (BBU) and radio frequency unit (RRU) of the base station are separated, and the RRU is provided with a baseband radio frequency interface that interconnects with the BBU and transmits data information. When the BBU is connected to the RRU, the data between the BBU and the RRU is exchanged, and the operation of re-establishing the connection is actually between the baseband physical layer processing board (PPC) and the RRU through the control and switching interface board (CSIB). accomplish. Usually, there are multiple RRUs in the WiMAX base station system, and one PPC can be connected to three RRUs at the same time...
