The radio frequency remote unit RRU of frame format, the BBU interface boards support a variety of IR frame formats, described
Method specifically may include steps of：
Step 201, the IR frame formats of the BBU interface boards are changed in a variety of IR frame formats,
And detect whether RRU accesses；
BBU interface boards support a variety of IR frame formats, and the conversion of IR frame formats can be by setting timer
To realize, whenever reaching timing cycle, BBU interface boards just change an IR frame format, meanwhile, inspection
Survey whether RRU accesses.
As a kind of preferred exemplary of the embodiment of the present application, the BBU interface boards connect including multiple optical fiber
Mouthful, the optical fiber interface is connected by optical fiber with RRU；The step 201 can specifically include as follows
Sub-step：
Sub-step S11, determine whether that at least one optical fiber interface has luminous power；
Judge whether that at least one optical fiber interface can receive the signal of RRU transmissions.
Sub-step S12, if so, then judging whether not all RRU corresponding to the BBU interface boards
Access the BBU interface boards；
If at least one optical fiber interface has luminous power, then it is assumed that at least one fiber link be present just
Normal RRU is attempting to access BBU.There is luminous power if none of optical fiber interface, then it is assumed that do not have
There is RRU attempting to access BBU, it is, therefore, not necessary to change IR frame formats.
There is at least one optical fiber interface that there is luminous power to be, determining whether current BBU interface boards pair
Whether all RRU answered do not access.
Sub-step S13, if so, then judging whether not all RRU corresponding to the BBU interface boards
The BBU interface boards were accessed with the 2nd IR frame formats；
If all RRU corresponding to current BBU interface boards are not accessed, then it is assumed that corresponding all
RRU IR frame formats are different from the IR frame formats that BBU is current.
If part RRU has accessed BBU interface boards, part RRU does not access BBU interface boards,
The IR frame formats for then thinking RRU corresponding to BBU interface boards are not identical, such case,
The frame format of BBU interface boards no matter how is changed, BBU interface boards can not all owned with corresponding
RRU frame format is identical.
When all RRU do not access BBU interface boards corresponding to BBU interface boards, determine whether
Whether all RRU corresponding to BBU interface boards did not access BBU interface boards with the 2nd IR frame formats.
Sub-step S14, if so, then changing the BBU interface boards in a variety of IR frame formats
IR frame formats.
If RRU once accessed BBU interface boards with the 2nd IR frame formats, and there are currently no access
It is successfully accessed BBU interface boards, it is likely that be due to that RRU is currently being resetted in start-up course.RRU
When resetting startup, IR frame formats will be changed into initial IR frame formats, after resetting start completion, RRU's
Frame format will be changed into the second frame format after updating.
In RRU resets start-up course, when not yet accessing BBU again, if BBU connects
The IR frame formats of oralia are converted to extended formatting from the second frame format, have resetted start completion in RRU
Need to access, IR frame formats and the RRU sides difference after being changed due to BBU will cause RRU temporarily without
Method access, it is necessary to wait BBU interface boards IR frame formats be converted to it is matching after could access,
It has impact on RRU turn-on time.
Step 202, when RRU is accessed, current IR frame formats are defined as the first IR frame formats；
After the first IR frame formats are determined in a variety of IR frame formats in BBU interface boards, stop turning
Change IR frame formats.
