Description
Technical Field
The invention relates to the field of wireless access networks, in particular to a method and a system for storing and reporting power failure information of O-RU equipment.
Background
The ORAN technology is a revolutionary technology of wireless communication networks that motivates 4G/5G communication network devices to move from custom, closed design to generalized, platform and white-box designs. The O-RU equipment is radio frequency front end remote equipment in the ORAN network, and has the characteristics of wide deployment range and huge quantity compared with other ORAN network equipment, so that the O-RU equipment is particularly focused on hardware platform and white box design, and the equipment cost is reduced as much as possible so as to improve the market competitiveness of products; the O-RU equipment often adopts a single-chip NORFLASH to store software, configuration, alarm and various record information; NORFLASH has the characteristics of high reliability and difficult change of information record, and is widely used for program storage of various electronic devices. However, the erase-write speed of the NORFLASH chip is slow, which generally requires several tens of ms; the O-RU equipment has higher power consumption, and in order to save the space and the cost of a power supply module, the design of equipment power-down protection is generally shorter, and the power-down protection time is only designed for a plurality of milliseconds.
In order to pursue development speed and efficiency, the software of the O-RU device generally adopts a Linux operating system and various open source software. The operating system can shield the bottom hardware drive, and the virtualized and logical bottom hardware is operated in a pure application layer software mode; taking the case of NORFLASH, the Linux operating system divides NORFLASH into partitions, where the partition that records various log information becomes a file partition. The Linux operating system records various necessary log information in real time in a file operating mode, so that the system can still inquire related information after power failure or restarting; the log information writing can be finally converted into NORFLASH operation through an operating system, firstly, the NORFLASH corresponding sector (region) is erased, and then new information is written; the relevant operation time will be greater than the erase write time of the norflah, on the order of tens of ms.
MPLANE is a management interface between ODU and O-RU defined by the ora standard; after the O-RU software checks the power failure condition of the equipment, the O-RU software tries to report the 'power supply fault' information through the MPLANE to inform the O-RU that the power failure occurs; the time length of the process is in the order of seconds; when the O-RU equipment is powered down, the expected general software processing flow is shown in fig. 1, and the expected processing result is as follows:
1) After power failure occurs, the O-RU equipment timely records relevant information generated by power failure alarm and can be queried after reset; 2) After the power failure occurs, the O-RU device reports a power failure alarm to a manager in the network through the MPLANE plane.
However, the processing flow is feasible in software principle, but has serious shortages due to the limitation of hardware conditions, and the power failure warning record and reporting function of the equipment can not be basically realized. There are the following disadvantages: 1) The internal power-down protection time of the O-RU equipment power supply is less than 10 milliseconds, and software alarm processing and reporting flows cannot be supported; 2) The erasing and writing time of the sector in the NORFLASH is tens of milliseconds, so that normal recording operation of a Linux file system cannot be realized, and local alarm information cannot be recorded; 3) The NORFLASH is powered down and enters an abnormal voltage area to perform erasure writing, so that the NORFLASH content is easy to be abnormal and even lost, and the equipment cannot be started; 4) The processing time of reporting alarm information on the network by the MPLANE is in the second level, so that normal reporting of the alarm can not be realized; the common method for solving the problems is to increase the power-down protection time of the power supply, add additional fast recording hardware components, bypass the Linux file system to operate NORFLASH and the like; these methods are not effective in solving the above-mentioned time problems encountered by power failure.
