Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a system startup method and a system startup device.
Background
The RRU (Radio Remote Unit) of the base station is configured to convert a baseband optical signal into a Radio frequency signal at a Remote end, amplify the Radio frequency signal, and transmit the Radio frequency signal.
In practical applications, the RRU is usually deployed near an antenna, such as the top of a tower, and therefore, the RRU needs to be operated by connecting a BBU (Base band Unit) of a Base station through an operation and maintenance machine room and then by using an optical fiber between the BBU and the RRU.
However, when the firmware version or the software version of the RRU fails, the RRU may not be normally started, and the operation and maintenance machine room may not be remotely connected to the RRU, and the RRU may only be repaired by a network port, a serial port, or even a near-end manner such as a JTAG (Joint Test action group) simulator. However, since the RRU is usually deployed at a place close to the antenna, such as the top of the iron tower, a professional is required to climb onto the top of the iron tower to detach the RRU device for repair, and then the RRU device is installed back after the repair is completed, which not only causes difficulty in the repair installation process of the RRU, but also increases the operation cost of the repair installation.
Disclosure of Invention
The embodiment of the invention provides a system starting method and a system starting device, which can reduce the operation cost of RRU repair and installation.
The embodiment of the invention provides a system starting method, which is applied to a base station Radio Remote Unit (RRU), and comprises the following steps:
loading a bootstrap program for booting the starting of the operating system of the RRU;
if the starting flag bit is detected to be established, starting a first operating system of the RRU through the bootstrap program; wherein the start flag is established under the condition that the second operating system of the RRU fails to start; the first operating system includes: a first firmware and a first software.
The embodiment of the invention provides a system starting device, which is applied to RRU and comprises:
a boot loading module, configured to load a boot program for booting an operating system of the RRU to start;
a first system starting module, configured to start a first operating system of the RRU through the bootstrap program if it is detected that a start flag is established; wherein the start flag is established under the condition that the second operating system of the RRU fails to start; the first operating system includes: a first firmware and a first software.
The embodiment of the invention has the following advantages:
in the embodiment of the invention, in the starting process of the RRU, after a bootstrap program for guiding the starting of an operating system of the RRU is loaded, whether a starting flag bit is established or not can be detected, and if the starting flag bit is established, a first operating system of the RRU can be started through the bootstrap program; wherein the start flag is established under the condition that the second operating system of the RRU fails to start; the first operating system includes: a first firmware and a first software.
Because the start flag is established when the second operating system of the RRU fails to start, when the start flag is detected, it indicates that the second operating system of the RRU cannot be started normally, at this time, the first operating system may be started, and may include a first firmware and a first software, where the first firmware may be used to implement normal start of the first operating system, and the first software may be used to implement normal communication between the RRU and the BBU. Therefore, under the condition that the second operating system of the RRU breaks down, the RRU can still be normally started through the first operating system, so that maintenance personnel can remotely access the RRU in an operation and maintenance machine room to remotely repair the RRU without needing a professional to mount the top of the iron tower to disassemble the RRU equipment for repair, the convenience for repairing the RRU can be improved, and the operation cost for repairing and installing the RRU can be reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Method embodiment one
Referring to fig. 1, a flowchart of a first embodiment of a system startup method of the present invention is shown, which may specifically include:
The embodiment of the present invention can be applied to a Radio Remote Unit (RRU) of a Base Station, where the Base Station can be a Base Transceiver Station (BTS) in GSM (Global System of Mobile communication) or CDMA (Code Division Multiple Access), an NB (NodeB, Base Station) in WCDMA (Wideband Code Division Multiple Access), an eNB or eNodeB (evolved node b, Base Station) in L TE (L ong Term Evolution), or a Base Station in 5G (fifth generation Mobile communication network).
The embodiment of the present invention may store a first operating system of the RRU in advance, where the first operating system specifically may include: a first firmware and a first software. The first firmware and the first software can be basic versions which are fully verified, and basic functions of starting an operating system, synchronizing optical fibers, remotely accessing, downloading the operating system and the like can be realized. For example, the first firmware can be used to implement normal boot of a first operating system, and the first software can be used to implement normal connectivity of the RRU with the BBU.
It can be understood that the storage location of the first operating system is not limited in the embodiment of the present invention, for example, a dedicated storage area may be reserved in a Flash (Flash EEPROM Memory) for storing the first operating system, and the first operating system and the second operating system may be located in different storage areas.
The second operating system may specifically be a normal version currently used by the RRU, and the second operating system may specifically include: second firmware and second software. The second firmware and the second software can be upgraded versions, and richer functions can be realized.
The start flag bit may be used to indicate a type of an operating system started by the RRU, for example, if the start flag bit is established, a First operating system is started, and if the start flag bit is not established, a second operating system is started, where the start flag bit is established when the second operating system of the RRU fails to start, specifically, after the RRU is powered on, a Boot program for guiding the operating system of the RRU to start, such as a First Stage Boot loader (FSB L), may be loaded, and a second operating system of a normal version is started by the Boot program, and in a process of starting the second operating system, if a failure occurs and results in a failure in starting the second operating system, the start flag bit may be established.
Therefore, through the embodiment of the invention, when the second operating system of the RRU has a fault, the RRU can still be normally started through the first operating system, so that a maintainer can remotely access the RRU in an operation and maintenance machine room, the remote repair of the RRU can be realized, a professional is not required to climb the top of an iron tower to disassemble RRU equipment for repair, the convenience for repairing the RRU can be improved, and the operating cost for repairing and installing the RRU can be reduced.
In an optional embodiment of the present invention, after the first operating system of the RRU is started, the method may further include the following steps:
step S11, repairing a second operating system of the RRU;
step S12, clearing the established starting zone bit;
and step S13, reloading the bootstrap program so as to start the repaired second operating system through the bootstrap program.
In the embodiment of the present invention, when the second operating system is abnormally started, the start flag may be established, and the RRU is restarted, and at this time, the established start flag is detected, and then the first operating system may be started.
Because the first operating system comprises the first software capable of realizing basic functions such as remote connection and network downloading, after the first operating system is successfully started, the RRU can download a problem-free version of the second operating system from a server storing the second operating system through network connection so as to cover the second operating system with an abnormal version in the current RRU, and further realize the automatic repair of the RRU.
After the second operating system of the RRU is repaired, the established start flag bit may be cleared, and the boot program is reloaded to start the repaired second operating system through the boot program.
It can be understood that the specific manner of repairing the second operating system is not limited in the embodiment of the present invention, for example, the second operating system of the current version may be repaired by downloading the second operating system of the new version; or, the specific fault can be repaired in a targeted manner according to the fault of the second operating system.
In an optional embodiment of the invention, the method may further comprise: and recording event information corresponding to the starting flag bit.
Specifically, in the process of starting the second operating system, if an exception occurs, which results in a failed start of the second operating system, a start flag may be established, and in addition, event information corresponding to the establishment of the start flag may be recorded. For example, the event information may include: firmware failure or software failure; among other things, firmware failures may include: CRC (cyclic redundancy Check) Check failure, etc.; software failures may include: failure of software package decompression, etc.
It is to be understood that the embodiment of the present invention does not limit the specific manner of recording the event information. In an application example of the present invention, the start flag may be set to include 8 bits, and each bit may be used to represent a common fault event. For example, the lowest position 1 of the flag bit is started, which indicates that the CRC check of the second firmware fails; the second position 1 of the flag bit is started to indicate that the software package is not decompressed and the like.
After the RRU is powered on, if it is detected that the start flag is established, event information corresponding to the establishment of the start flag may be further determined and recorded according to a bit of a 1 in the start flag, that is, according to the bit of the 1, a failure cause that the second operating system cannot be normally started may be determined, and thus the failure may be automatically repaired. For example, if it is determined that the second firmware in the second operating system fails, a new version of the second firmware may be downloaded from the server to automatically repair the current second firmware; for another example, if it is determined that the second software in the second operating system fails, a new version of the second software may be downloaded from the server to automatically repair the current second software, and so on. Even if some faults which cannot be automatically repaired exist, maintenance personnel can remotely access the RRU in the operation and maintenance machine room through the first operating system to remotely repair the faults.
In the embodiment of the invention, the second operating system can be upgraded, but the first operating system is not upgraded, so that the stability of the first operating system is ensured.
In an optional embodiment of the present invention, after loading a boot program for booting an operating system of the RRU to start, the method may further include: and if the starting flag bit is not established, starting a second operating system of the RRU through the bootstrap program.
Specifically, after the RRU is powered on, a boot program for booting the operating system of the RRU to start may be loaded, and if it is detected that the start flag is not established, which indicates that the second operating system is not abnormal, and the second operating system may be started normally, the second operating system may be started through the boot program.
In an optional embodiment of the present invention, the second operating system may specifically include: the starting of the second operating system of the RRU may specifically include the following steps:
step S21, establishing a starting zone bit;
step S22, starting the second firmware;
step S23, if the second firmware is successfully started, clearing the established start flag, and starting the second software; if the second firmware fails to start, the boot program is reloaded;
step S24, if the second software fails to start, establishing a start flag, and reloading the boot program.
Specifically, before the second operating system is started, a start flag may be established, and then whether to clear the start flag may be determined according to whether the second operating system can normally complete the start.
After the start flag bit is established, the second firmware can be started first, and if the second firmware is started successfully, the established start flag bit can be cleared, and the second software can be started; if the second firmware fails to start, the boot program can be reloaded, in this case, because the start flag bit is not cleared, the start flag bit is detected after the restart, so as to start the first operating system, and automatically repair the second operating system, thereby realizing self-protection and automatic repair of the second firmware under the condition of version upgrade or accidental damage of the second firmware.
In an optional embodiment of the present invention, after the start flag is established and before the second firmware is started, the method may further include the steps of: starting a timer;
after the second firmware is started and before the second software is started, the method may further include the steps of: if the timer is overtime, the bootstrap program is reloaded; and if the timer is not overtime and the second firmware is successfully started, closing the timer.
The timer may specifically be a watchdog timer, and may be configured to prevent a start exception caused by a loading failure of the second firmware. In the starting process of the second firmware, if the abnormal starting condition caused by the firmware version error occurs, the watchdog timer is triggered to reset when the watchdog timer is not closed and no watchdog feeding action exists, and the boot program is reloaded. In this case, since the boot flag is not cleared, it is detected after the reboot that the boot flag is established, so that the first operating system is booted and the second operating system is self-repaired.
After the second firmware is successfully started, the watchdog timer can be closed, and the established start flag bit is cleared, which indicates that the second firmware is not abnormal, and the protection of the second firmware is completed.
In a specific application, the optical interface link configuration of the RRU is completed in software, and if the software version is damaged or there is a problem, the optical fiber link is broken, in this case, a professional is also required to disassemble the RRU device for repair. Therefore, in order to avoid the above situation, the embodiment of the present invention performs self-protection and automatic repair on the second software in the second operating system.
Specifically, after the second firmware is successfully started, the second software may be started, if the second software fails to be started, a start flag bit may be established, and the board is restarted by using the control command word to reload the boot program, and in this case, since the start flag bit is not cleared, it is detected that the start flag bit is established after the restart, so as to start the first operating system and perform self-repair on the second operating system, therefore, in a case where a software package of the second software is damaged, self-protection and automatic repair of the second software may be implemented, and further, a situation that a software version is damaged or an optical fiber is broken due to a problem, and the operation and maintenance machine room cannot remotely access the RRU may be avoided.
To sum up, in the starting process of the RRU, after loading a bootstrap program for guiding the operation system of the RRU to start, the embodiment of the present invention may detect whether a start flag bit is established, and if it is detected that the start flag bit is established, the first operation system of the RRU may be started through the bootstrap program; wherein the start flag is established under the condition that the second operating system of the RRU fails to start; the first operating system includes: a first firmware and a first software.
Because the start flag is established when the second operating system of the RRU fails to start, when the start flag is detected, it indicates that the second operating system of the RRU cannot be started normally, at this time, the first operating system may be started, and may include a first firmware and a first software, where the first firmware may be used to implement normal start of the first operating system, and the first software may be used to implement normal communication between the RRU and the BBU. Therefore, under the condition that the second operating system of the RRU breaks down, the RRU can still be normally started through the first operating system, so that maintenance personnel can remotely access the RRU in an operation and maintenance machine room to remotely repair the RRU without needing a professional to mount the top of the iron tower to disassemble the RRU equipment for repair, the convenience for repairing the RRU can be improved, and the operation cost for repairing and installing the RRU can be reduced.
Method embodiment two
Referring to fig. 2, a flowchart of a second embodiment of a system startup method of the present invention is shown, which may specifically include:
after the RRU is powered on, the FSB L may be loaded to boot the operating system of the RRU.
specifically, if the start flag is established, which indicates that the second operating system fails and cannot be normally started, step 204 is executed to start the first operating system; if the boot flag is not set, indicating that the second operating system can be booted normally, step 209 is performed to boot the second operating system.
in a specific application, the uboot (Universal Boot L loader) is an open source code item following the terms of GP L, and is used for system Boot, the first firmware of the embodiment of the present invention may include a first uboot and a first core (kernel), where the first uboot and the first core may be sufficiently verified and stable versions, and the first uboot is used for starting the first kernel (core) of the first operating system.
through the first software, the normal communication between the RRU and the BBU can be realized.
specifically, a new version of the second operating system may be downloaded, overwriting the current version of the second operating system; or, the fault can be repaired in a targeted manner according to the fault reason recorded by the starting flag bit.
after the second operating system repair is complete, the established boot flag may be cleared.
after restarting the RRU, one can jump to step 202 to reload the FSB L and determine if the start flag has been established, and because the start flag has been cleared, the repaired second operating system can be started.
the second operating system may be started when it is detected that the start flag is not established, the start flag is established first before the start, and whether to clear the start flag may be determined subsequently according to whether the second operating system can complete the start normally.
the watchdog timer may be used to prevent a boot exception caused by a second firmware load failure.
similar to the first firmware, the second firmware may include a second uboot and a second core. And in the process of starting the second firmware, starting the second uboot firstly, and then starting the second core through the second uboot.
specifically, the second uboot is started first, whether the watchdog timer is overtime is judged, if abnormal starting conditions such as a second firmware version error occur, the watchdog timer is not closed and reset is triggered when no dog feeding action exists, at this time, since the starting flag bit is not cleared, step 202 is executed after the watchdog is restarted and the starting flag bit is judged again, so that step 204 can be performed to automatically repair the fault. If the second uboot is successfully started, a second core is started, and similarly, whether the watchdog timer is overtime is judged, if the situation that the start is abnormal due to the error of the version of the second firmware and the like occurs, the watchdog timer is not closed and the watchdog timer is triggered to reset when no dog feeding action exists, at this time, because the start flag bit is not cleared, the step 202 is executed after the restart, and the start flag bit is judged again, so that the step 204 can be entered to automatically repair the fault. Therefore, self-protection and automatic repair of the second firmware can be realized.
if the second core is successfully started and the watchdog timer has not timed out, the watchdog timer may be turned off.
thus, the established boot flag can be cleared if the second firmware boot is successful.
after the second firmware boot is successful, the second software may be launched.
in the second software starting process, it may be determined whether the second software starting is abnormal, for example, if the second software starting is abnormal due to the failure of decompression of both the main and standby software packages, the start flag may be established, then the RRU is restarted to jump to step 202, and it is determined whether the start flag is established again, so that step 204 may be entered to automatically repair the fault of the second software. Therefore, self-protection and automatic repair of the second software can be realized.
To sum up, the embodiment of the present invention improves the starting process of the RRU, and after loading a bootstrap program for guiding the operation system of the RRU to start, it can be detected whether a start flag bit is established, and if it is detected that the start flag bit is established, the first operation system of the RRU can be started through the bootstrap program; wherein the start flag is established under the condition that the second operating system of the RRU fails to start; the first operating system includes: a first firmware and a first software.
Because the start flag is established when the second operating system of the RRU fails to start, when the start flag is detected, it indicates that the second operating system of the RRU cannot be started normally, at this time, the first operating system may be started, and may include a first firmware and a first software, where the first firmware may be used to implement normal start of the first operating system, and the first software may be used to implement normal communication between the RRU and the BBU. Therefore, under the condition that the second operating system of the RRU breaks down, the RRU can still be normally started through the first operating system, so that maintenance personnel can remotely access the RRU in an operation and maintenance machine room to remotely repair the RRU without needing a professional to mount the top of the iron tower to disassemble the RRU equipment for repair, the convenience for repairing the RRU can be improved, and the operation cost for repairing and installing the RRU can be reduced.
