Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
One of the core ideas of the embodiment of the application is that when the IR frame formats of the BBU interface board and the RRU are not consistent, the BBU interface board is adaptively converted to the IR frame format same as that of the RRU, so that the RRU can receive the version update indication message sent by the BBU in the original IR frame format. And after the RRU adopts the version update indication message to update the IR frame format, updating the IR frame format of the BBU interface board.
Referring to fig. 1, a flowchart of a step of embodiment 1 of a method for converting an IR frame format of a BBU interface board of the present application is shown, where the BBU interface board corresponds to a plurality of radio remote units RRUs in a first IR frame format, and the method may specifically include the following steps:
the first IR frame format is an old IR frame format of the RRU, and when a base station is newly built or the base station is expanded from a single mode to a dual mode, the IR frame format of the BBU is an IR frame format with a newer version. When the frame format of the RRU is different from that of the BBU, the RRU cannot be accessed to the BBU.
In the embodiment of the application, the BBU interface board is adaptively converted to the same first IR frame format as the RRU.
after the IR frame format of the BBU interface board is converted into the first IR frame format, the RRU may access the BBU in the first frame format. At this time, the BBU may send a version update indication message to the RRU. The version update indication message includes information that the RRU is expected to access the BBU in the second IR frame format. The second IR frame format is a newer version IR frame format that the BBU side expects to employ.
And the RRU downloads an update file in a second IR frame format according to the version update indication message, and then updates the IR frame format from the first IR frame format to the second IR frame format.
And after the RRU updates the IR frame format to a second IR frame format, converting the IR frame format of the BBU interface board into the second IR frame format, so that the RRU can access the BBU in the second IR frame format.
In the embodiment of the application, the IR frame format of the BBU interface board is adaptively converted into the IR frame format with the older version of the RRU, so that the RRU can receive the version update indication message sent by the BBU in the original IR frame format. And after the RRU adopts the version update indication message to update the IR frame format, updating the IR frame format of the BBU interface board so that the RRU can be accessed to the RRU in the new IR frame format.
The RRU is not required to be upgraded by directly connecting the RRU to the near end manually, so that the RRU is accessed, the manual operation cost is greatly reduced, and the increase of engineering complexity and the increase of construction time caused by manual misoperation are greatly reduced.
Referring to fig. 2, a flowchart of a step of embodiment 2 of a method for converting an IR frame format of a BBU interface board of the present application is shown, where the BBU interface board corresponds to a plurality of radio remote units RRUs of a first IR frame format, and the BBU interface board supports a plurality of IR frame formats, and the method specifically includes the following steps:
the BBU interface board supports a plurality of IR frame formats, the conversion of the IR frame formats can be realized by setting a timer, the BBU interface board converts the IR frame formats once when a timing period is reached, and meanwhile, whether the RRU is accessed or not is detected.
As a preferred example of the embodiment of the present application, the BBU interface board includes a plurality of optical fiber interfaces, and the optical fiber interfaces are connected to the RRUs through optical fibers; the step 201 may specifically include the following sub-steps:
substep S11, determining whether at least one optical fiber interface has optical power;
and judging whether at least one optical fiber interface can receive the signal sent by the RRU.
Step S12, if yes, judging whether all RRUs corresponding to the BBU interface board are not accessed to the BBU interface board;
and if at least one optical fiber interface has optical power, the RRU with at least one normal optical fiber link is considered to be trying to access the BBU. If none of the fiber interfaces has optical power, then no RRUs are considered to be attempting to access the BBU, and therefore, it is not necessary to convert the IR frame format.
And if at least one optical fiber interface has optical power, further judging whether all the RRUs corresponding to the current BBU interface board are not accessed.
Step S13, if yes, judging whether all RRUs corresponding to the BBU interface board have not been accessed to the BBU interface board in the second IR frame format;
and if all the RRUs corresponding to the current BBU interface board are not accessed, the IR frame formats of all the corresponding RRUs are considered to be different from the current IR frame format of the BBU.
If some RRUs have already been connected to the BBU interface board and some RRUs have not, it is considered that the IR frame formats of the RRUs corresponding to the BBU interface board are not completely the same, and in this case, no matter how the frame formats of the BBU interface board are converted, the frame formats of the BBU interface board and all corresponding RRUs cannot be made the same.
And when all the RRUs corresponding to the BBU interface board are not accessed to the BBU interface board, further judging whether all the RRUs corresponding to the BBU interface board are not accessed to the BBU interface board in the second IR frame format.
And a substep S14, if yes, converting the IR frame format of the BBU interface board among the plurality of IR frame formats.
If the RRU has accessed the BBU interface board in the second IR frame format once but has not accessed the BBU interface board successfully now, it is likely that the RRU is currently in the reset start process. When the RRU is reset and started, the IR frame format is changed into an initial IR frame format, and after the reset and start are completed, the frame format of the RRU is changed into an updated second frame format.
In the process of resetting and starting the RRU, when the BBU can not be accessed again, if the IR frame format of the BBU interface board is converted from the second frame format to other formats, the RRU needs to be accessed after the RRU is reset and started, and the RRU can not be accessed temporarily because the IR frame format converted by the BBU is different from the IR frame format converted by the RRU side, and the RRU can be accessed after the IR frame format of the BBU interface board is converted to be matched with the IR frame format, so that the access time of the RRU is influenced.
and stopping converting the IR frame format after the first IR frame format is determined in the plurality of IR frame formats of the BBU interface board.
The RRU can be accessed to the BBU only when the IR frame format of the BBU interface board is the same as that of the RRU. Therefore, when detecting that the RRU is accessed, the current IR frame format of the BBU interface board is the frame format of the RRU.
The flow office accessed by the RRU may specifically include two parts:
1. synchronizing the optical fiber links;
establishing synchronization of an optical fiber link layer and completing rate negotiation of a data link layer;
2, establishing a channel between the BBU and the RRU;
1) the RRU obtains RRU level information in a physical layer control word: and RRU ID. The BBU needs to reasonably set the first stage RRU ID of each optical port to ensure that the BBU can identify the RRU by the RRU ID.
2) The RRU sends a UDP (User Datagram Protocol) full-network broadcast message to the BBU, carrying a Media Access Control (MAC) address and RRU ID information.
3) And the BBU identifies the RRU according to the RRU ID information, allocates an IP address for the RRU, and transmits the RRU to the RRU through the whole network broadcasting. And all RRUs on the link intercept the IP addresses of the RRUs and the BBU according to the RRU ID information in the broadcast message.
4) And a link is established between the BBU and the RRU, and the BBU is a server side.
5) And the RRU sends a channel establishment request message to the BBU through the established link, and the BBU responds the channel establishment configuration message to the RRU through the link.
6) And completing the establishment of the channel between the RRU and the BBU, and performing subsequent messages on the link.
when the BBU interface board is converted to the first IR frame format, the RRU can access the BBU in the first IR frame format. In the access process, the RRU may carry version information in a channel establishment request message sent to the BBU, where the version information indicates a version of an IR frame format currently adopted by the RRU. And if the IR frame format currently adopted by the RRU is not the IR frame format expected by the BBU, the BBU sends version update indication information to the RRU, and the RRU is required to update the IR frame format to the expected IR frame format.
As a preferred example of the embodiment of the present application, the step 204 may specifically include the following sub-steps:
a substep S21, receiving a version update response message sent by the RRU; the version update response message is sent by the RRU after the IR frame format is converted into a second IR frame format by adopting the version update indication message;
and the RRU sends a version update response message to the BBU after converting the IR frame format from the first IR frame format to the second IR frame format by adopting the version update indication message, and the version update response message indicates that the IR frame format of the RRU is updated.
A substep S22, determining whether version update response messages sent by all RRUs corresponding to the BBU interface board are received;
and judging whether version updating response messages sent by all RRUs corresponding to the BBU interface board are received.
And a substep S23, if yes, converting the IR frame format of the BBU interface board into the second IR frame format.
And after receiving version update response messages sent by all RRUs corresponding to the BBU interface board, converting the IR frame format of the BBU interface board into a second IR frame format.
In this embodiment, by continuously converting the IR frame format of the BBU interface board, it is detected whether the RRU is accessed; the IR frame format of the BBU interface board when the RRU is accessed is determined to be the IR frame format of the RRU, the IR frame format of the BBU interface board does not need to be modified manually for many times, and the IR frame format of the BBU interface board can also be converted into the original IR frame format of the RRU. And enabling the RRU to receive the version update indication message sent by the BBU in the original IR frame format. After the RRU adopts the version update indication message to update the IR frame format, the IR frame format of the BBU interface board is updated, so that the RRU can be accessed to the RRU in the new IR frame format, the manual operation cost is greatly reduced, and the increase of engineering complexity and construction time caused by manual misoperation is greatly reduced.
Fig. 3 is a flowchart illustrating an embodiment of IR frame format adaptive conversion processing of a BBU interface board according to the present application. The method specifically comprises the following steps:
305, judging whether the flag bit F1 of each RRU on the BBU interface board is 0; if yes, go to step 306; if not, go to step 307;
and setting a flag bit F1 for each RRU on the BBU interface board, wherein the initial values of the flag bits are 0, which indicates that the RRU has not been accessed in the expected IR frame format, and after the RRU has been accessed in the expected IR frame format, setting F1 to be 1, which indicates that the RRU has been accessed in the expected Ir frame format.

as a preferred example of the embodiment of the present application, the BBU interface board is provided with a flag bit for indicating whether the RRU accesses the BBU in the second IR frame format; the flag bit is 0, which indicates that the RRU has not accessed the BBU in the second IR frame format; the flag bit is 1, which indicates that the RRU has access to the flag bit of the BBU in the second IR frame format;
the step 403 may specifically include the following sub-steps:
and a substep S31, determining whether the flag bits of all RRUs corresponding to the BBU interface board are all 0.
And if the flag bits of all the RRUs corresponding to the BBU interface board are 0, namely all the RRUs are not accessed to the BBU interface board in the second IR frame format, converting the IR frame formats of the BBU interface board in the plurality of IR frame formats.
If any RRU corresponds to the F1 value of 1, the corresponding BBU interface board stops performing IR frame format conversion.
