Embodiment Construction

[0019] The present invention takes the implementation in the CPRI interface as an example to illustrate the specific implementation.

[0020] After the connection is established, the BBU sends the identification number of each RRU to each RRU respectively, and the value range is [0, 0FEH]. As shown in Figure 2, in the reset information defined by the CPRI standard, a bit of the control word CW130 occupying the control word channel No. 130 is the reset bit, and this bit sends 0 when it does not request a reset. When a reset is requested, the RRU will receive More than 10 reset messages whose reset bit is 1. In the control word reserved for equipment manufacturers, define the control word CW16 No. 16 in the control word channel as the reset address, and the reset address is one byte.

[0021] When the BBU intends to reset a certain RRU, for example, when performing a reset operation on an RRU whose identification number is n (0≤n≤0FEH), first set the reset address to n, and the...

Abstract

The present invention discloses a method for replacement Multistage distal RF Module unit by baseband unit, first, baseband unit set the replacement information to control the word module's replacement bit and replacement address, and sent the replacement information out; Then every distal RF Module seriatim receive and test the replacement information, if the test result is request distal RF Module or the replacement address is overall situation of reset logo then replace the distal RF Module. The baseband unit (BBU) can respectively and independently reset the RRU, and it doesn't infect other work. At the same time, it supports the whole chain's replacement function and has good compatibility with the existing technology in plans, which are realized conveniently, as well as easily.

Description

technical field [0001] The invention relates to a method for a baseband unit in a wireless communication system to reset a multistage remote radio frequency unit. Background technique [0002] In recent years, the development of wireless communication system architecture has gradually evolved into such a trend: separate the BBU (Base Band Unit, baseband unit) from the RRU (Remote Radio Unit, remote radio frequency unit), and use long-distance transmission means (such as optical fiber , cables) connect the BBU with multiple RRUs, and then place the RRUs in various places where they are needed. This architecture improves the flexibility of networking on the one hand, and reduces the maintenance cost of the network on the other hand. Therefore, this architecture is more and more recognized by users, and there are more and more application occasions. In recent years, this architecture has been written into certain industry standards, such as OBSAI (Open Base Station Architectu...
