Embodiment Construction

[0034] The basic idea of ​​the present invention is: in the present invention, the eRRU mainly includes the eRRU radio frequency processing board, and the eBBU mainly includes the eBBU main control board and the eBBU physical board. After the eRRU radio frequency processing board is started, the physical channel between the eRRU radio frequency processing board and the eBBU physical board is opened first by using the CPRI (Common Public Radio Interface) interface control word between the eRRU radio frequency processing board and the eBBU physical board; then, the eRRU radio frequency The processing board actively initiates a network configuration packet request to the eBBU main control board to obtain PID information, and the eRRU establishes a UDP link with the eBBU.

[0035] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

Abstract

A method for initiating evolution Remote Radio Unit (eRRU) and a radio processing board are provided in the present invention, wherein, the method for initiating the eRRU includes the following steps: a physical channel is established between the eRRU radio processing board and the physical board of the evolution Baseband Unit (eBBU) which is a baseband resource pool, and a User Datagram Protocol (UDP) link is established between the eRRU radio processing board and the eBBU main control board. The present invention ameliorates the configuration process for initiating the eRRU. The eRRU radio processing board transmits initiatively a physical channel establishment request to the eBBU physical board, thereby obtaining the networking topology information of the eRRU initiatively without manual configuration of the networking topology information of the eRRU in the background, furthermore improving the efficiency. In addition, the eRRU radio processing board transmits initiatively a network configuration packet request to the eBBU main control board and establishes the UDP link so that the initiation of the eRRU becomes a normal and controllable process, and therefore the evolution Node B (eNodeB) can also work normally.

Description

technical field [0001] The present invention relates to the field of wireless mobile communication, in particular to a method for starting self-configuration of an evolution remote radio unit (eRRU, evolution RemoteRadio Unit) in a wireless mobile communication system long term evolution (LTE, Long Term Evolution). Background technique [0002] At present, the industry generally adopts a base station (NodeB) system architecture consisting of a baseband resource pool (BBU)+RRU. In the LTE network architecture, eNodeB also adopts a software and hardware system architecture consisting of eBBU+eRRU. The start-up process of the eBBU includes two parts: the normal start of the eBBU and the normal start of the eRRU. If the eRRU cannot be started normally, the entire eNodeB will not work normally. At present, eRRU startup is a passive process, such as figure 1 As shown, eRRU startup mainly includes the following steps: [0003] Step 101, after the eBBU main control board is powere...
