Description of drawings
Fig. 1 is the flow process that regularly reports black box information;
Fig. 2 is the flow process of request black box information.
Embodiment
With reference to accompanying drawing 1, regularly report the flow process of black box information to be:
1 black box makes up
RRU powers on, and during the initialization physical memory, marks a zone in physical memory, is called reserved memory.When RRU resetted, the power-up initializing program was not done clear operation to reserved memory, and the content of reserved memory can remain unchanged.
Therefore, can use the black box of reserved memory as the record operation information.The size of reserved memory is by actual needs and physical memory decision.
For example: the last physical memory of RRU is 32MB, and address space is [0,0x1ffffff], and the size that reserved memory is set is 512KB, and address realm is [0x1f80000,0x1ffffff].
Also can use nonvolatile memory as black box.
2 to the black box writing information
Provide one to write function, call, to the black box writing information by high level.
At the first address of black box, reserve 4 bytes as Information sign, when Information sign is not 0, show that black box is meaningful.When call write function after, Information sign is put number.
A reseting hook subfunction is provided, calls when resetting to black box and write necessary information before resetting, program pointer for example, stack pointer etc.When the RRU operation occurs when causing resetting, can recording reset circuit unusually.
For example: at black box first address 0x1f80000, reserve 4 bytes, when for the first time to the black box writing information, putting Information sign is 0x12345678.Behind each writing information, write pointer is offset backward.
3 report black box information
RRU adopts 3 kinds of modes to report black box information:
(1) regularly reports;
(2) reset and report;
(3) request reports
After reporting successfully, remove Information sign.
Regularly report
After BBU and RRU started, background net management was provided with order to the RRU transmission timer, thus the frequency that control reports, and it is 1 hour that timer for example is set.
Behind the timer expiry, whether RRU inspection message sign is 0x12345678, if with regard to reporting information, and with the total length zero clearing of writing information, the read-write pointer all points to the black box first address.
Because the restriction of the communication protocol between RRU and the communication equipment possibly can't once report long data, therefore by the backstage maximum data length that single reports is set, report several times, report up to the information of black box to finish.
Reset and report
Realized a monitoring process on the RRU, after RRU resets, after monitoring process is received the message that powers on, whether RRU inspection message sign is 0x12345678, if, with regard to reporting information, and with the total length zero clearing of writing information, the read-write pointer all points to the black box first address.
Request reports (with reference to accompanying drawing 2)
Background net management sends request by BBU OAM to RRU and reports order, and after RRU received, whether the inspection message sign was 0x12345678, if with regard to reporting information, and with the total length zero clearing of writing information, the read-write pointer all points to the black box first address.
