Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] The embodiment of the present invention is applicable to the C-RAN architecture. Under the C-RAN architecture, the RRU is connected to the BBU in the baseband pool through an optical switching device; the RRU is connected to the optical switching device through an optical fiber, and the BBU in the baseband pool is connected to the optical switching device through an optical fiber; the control device is connected through an Ethernet l...

Abstract

The embodiment of the invention discloses an access method and device for an RRU and relates to the field of wireless communication. The access method and device are used for solving the problem that in the prior art, the RRU can not get access under a C-RAN infrastructure. First RRU identification is distributed to the RRU through an optical switching device, access request information which is sent by the RRU and carries the first RRU identification is intercepted through the optical switching device and forwarded to a control device, the control device can transmit an optical interface number, on the side of the optical switching device, of the RRU to a BBU distributed to the RRU through the process that the BBU is distributed to the RRU, and the optical switching device is instructed to perform optical interface internal interconnection, and then the BBU can distribute second RRU identification to the RRU according to the optical interface number, wherein the second RRU identification is used for getting access to the BBU. The problem that the RRU can not get access under the C-RAN infrastructure is solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an RRU access method and device. Background technique [0002] In the traditional radio access network (Radio Access Network, RAN) architecture, the baseband processing unit (Building Base band Unit, BBU) and the remote radio frequency unit (Radio Remote Unit, RRU) are directly connected through optical fibers, and the connection relationship is fixed. figure 1 It shows a schematic diagram of an RRU accessing a BBU under the RAN architecture. The RRU in the search synchronization state can establish a fiber link synchronization process with the BBU. After the RRU and the BBU establish fiber link synchronization, the BBU assigns an RRU identifier (RRU ID) to the RRU. The RRU ID is determined by the optical port on the BBU side and the connection The series of RRUs on the optical fiber between the BBU and the RRU is composed of the number of BBU side optical ports uni...
