Embodiment Construction

[0022] Refer to attached figure 1 , the process of regularly reporting black box information is as follows:

[0023] 1 black box build

[0024] When the RRU is powered on and initializes the physical memory, an area in the physical memory is designated, which is called reserved memory. When the RRU is reset, the power-on initialization program does not clear the reserved memory, and the contents of the reserved memory can remain unchanged.

[0025] Therefore, reserved memory can be used as a black box for recording running information. The size of reserved memory is determined by actual needs and physical memory.

[0026] For example: the physical memory on the RRU is 32MB, the address space is [0, 0x1ffffff], the reserved memory size is set to 512KB, and the address range is [0x1f80000, 0x1ffffff].

[0027] It is also possible to use non-volatile memory as a black box.

[0028] 2 Write information to the black box

[0029] Provide a write function, which is called by th...

Abstract

Being in use for solving issue that it is difficult to obtain and unable to monitor running info of radio frequency unit at remote end (RFURE) currently, the method includes following parts and steps:a block of reserved memory as black box for recording running info is laid out from the physical memory of RFURE in wireless communication system; higher level calls write function to write info to the black box, and info symbol to indicate whether the black box contains info content is setup at first address of the black box; RFURE reports info of black box, and eliminates the info symbol aftersuccessful report. After RFURE is reset, the black box can conserve recorded info before resetting. The black box can locate reset reason caused by malfunction, and can record integrated journal infoso as to be convenient to analyze malfunction of RFURE.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for recording the operation information of a remote radio frequency unit. Background technique [0002] In the development of wireless communication, more and more base station equipment is developing towards the architecture of baseband pool unit (BBU) + remote equipment unit. The typical application of remote equipment is remote radio unit (RRU), but not only limited to this application. Under the architecture of BBU+RRU, generally RRU belongs to the managed object, and BBU belongs to the managed object. One BBU can manage multiple RRUs, and the BBU and RRU are connected through transmission cables. The separation of remote equipment and communication equipment becomes a trend. The operation information of RRU is difficult to obtain and cannot be monitored. A large global structure can be used to record running information, but if the RRU is reset mid...
