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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
In order to solve the problems of serious waste of human resources and low accuracy of the method for detecting the RRU channel in the prior art, the embodiment of the invention provides a method for automatically detecting the RRU channel, namely, after determining the corresponding RRU to be detected according to the RRU identification information carried in the received first channel quality parameter, sequentially performing channel detection on each channel corresponding to the RRU to be detected based on the second channel quality parameter received again, and determining an abnormal channel according to the detection result corresponding to each channel, thereby realizing the function of automatically detecting the RRU channel.
The present invention will be described in detail with reference to specific examples, but it is to be understood that the present invention is not limited to the examples.
Referring to fig. 1, in the embodiment of the present invention, the following may be used, but not limited to: performing RRU channel detection on a User Equipment (UE), wherein a specific flow of the RRU channel detection method is as follows:
step 100: and determining the corresponding RRU to be detected based on the received RRU identification information carried in the first channel quality parameter.
Preferably, if the antenna attribute is a smart antenna, the weight information of the smart antenna may cause imbalance of the transmission power of each channel corresponding to the RRU, so that, to ensure the accuracy of channel detection, the antenna attribute needs to be set as a non-smart antenna before step 100 is executed.
Specifically, when step 100 is executed, the following steps may be adopted, but not limited to:
first, the UE sends a first reference signal for channel estimation to the base station, and preferably, the first reference signal may be, but is not limited to: channel Sounding Reference Signal (SRS).
Then, the base station performs channel estimation based on the first SRS transmitted by the UE, and transmits the first channel quality parameter obtained after the channel estimation to the UE.
And finally, the UE determines the corresponding RRU to be detected based on the received RRU identification information carried in the first channel quality parameter.
For example: the UE1 sends an SRS1 to the base station A, after the base station A receives the SRS1 sent by the UE1, the base station A carries out channel estimation according to the SRS1 and sends a channel quality parameter 1 obtained after the channel estimation to the UE1, and the UE1 determines that the RRU to be detected is the RRU1 according to the RRU identification information 1 carried in the received channel quality parameter 1.
Step 110: and determining each channel corresponding to the RRU to be detected, and sequentially detecting each channel based on the second received channel quality parameters to obtain a corresponding detection result.
Specifically, when step 110 is executed, the following steps may be adopted, but not limited to:
firstly, the UE connects with the BBU corresponding to its own camping base station, wherein the connection mode may adopt but is not limited to: the connection is performed through a predetermined Universal Serial Bus (USB) interface.
Then, the UE determines each channel corresponding to the RRU to be detected, and selects one channel from the multiple channels corresponding to the RRU to be detected, and preferably, selects the first channel for detection according to the preset channel identification information of each channel.
Secondly, in the prior art, a Local Maintenance Terminal (LMT) is used to instruct a BBU to close an RRU channel, so that in order to fully utilize existing resources for channel detection and avoid the problems of resource waste and excessive cost caused by repeated resource development, a UE may still instruct the BBU to close all channels except a first channel through the LMT, and specifically, the following manner may be adopted:
and the UE sends a channel detection instruction to the LMT, and instructs the LMT to notify the BBU to close all other channels except the first channel to start channel detection, wherein the channel detection instruction carries the BBU identification information corresponding to the BBU, the RRU identification information corresponding to the RRU to be detected, and the channel identification information of the first channel corresponding to the RRU to be detected.
After receiving a channel detection instruction sent by the UE, the LMT determines a corresponding BBU based on BBU identification information carried in the channel detection instruction, and sends a channel closing instruction to the BBU, wherein the channel closing instruction carries RRU identification information corresponding to the RRU to be detected and channel identification information of a first channel corresponding to the RRU to be detected. After receiving a channel closing instruction sent by the LMT, the BBU closes channels corresponding to all other RRUs except the RRU to be detected based on RRU identification information corresponding to the RRU to be detected carried in the channel closing instruction, closes all other channels except the first channel in the RRU to be detected based on the channel identification information corresponding to the first channel carried in the channel closing instruction, and sends prompt information to the UE through the USB interface to prompt the UE that all other channels except the first channel have been successfully closed.
Finally, after receiving the prompt message sent by the BBU, the UE sends a second SRS to the base station again, performs channel detection on the first channel based on the received channel quality parameters returned by the base station based on the second SRS again, and judges whether a corresponding detection result is obtained within a preset time range, if so, the detection result of the first channel is retained, and the detection method is continuously adopted to perform channel detection on the second channel; otherwise, judging that the channel detection of the first channel fails, continuously judging whether the channel detection frequency of the first channel is greater than a preset threshold value, if so, directly skipping the first channel, selecting a second channel for channel detection, or directly quitting the channel detection process according to the selection of a user; otherwise, continuing to perform channel detection on the first channel based on the received third channel quality parameter.
For example: continuing with the above example, the UE1 is connected to the USB interface 1 of the BBU1 (the BBU corresponding to the base station where the UE1 resides itself), and when determining that the RRU1 corresponds to 8 channels based on the number of channels corresponding to the RRU1 input by the user, automatically selects the channel 1 from the 8 channels (i.e., channel 1-channel 8) corresponding to the RRU1 to perform channel detection, and sends a channel detection instruction 1 to the LMT.
After receiving the channel detection instruction 1 sent by the UE1, the LMT determines that the corresponding BBU is the BBU1 based on the BBU identification information 1 carried in the channel detection instruction 1, and sends a channel closing instruction 1 to the BBU 1.
After receiving the channel closing instruction 1 sent by the LMT, the BBU1 determines, based on the RRU identification information 1 carried in the channel closing instruction 1, that an RRU that needs to be reserved is an RRU1, and closes channels corresponding to all other RRUs except the RRU1, and determines, based on the channel identification information 1 carried in the channel closing instruction 1, that a channel that needs to be reserved in the RRU1 is a channel 1, and closes all other channels except the channel 1, and sends a prompt information 1 to the UE1 through the USB interface 1, so as to prompt the UE1 that all other channels except the channel 1 have been successfully closed.
After receiving the prompt information 1 sent by the BBU1, the UE1, when determining that all channels except channel 1 have been successfully closed, sends SRS2 to the base station a, and performs channel detection on channel 1 based on the received channel quality parameter 2 returned by the base station a based on SRS 2.
The UE1 determines whether a corresponding detection result is obtained within 10 seconds (i.e., the preset time range is 10 seconds), and if so, continues to use the channel detection method for the channel 1 to automatically perform channel detection for the channel 2; otherwise, judging that the channel detection on the channel 1 fails, continuously judging whether the channel detection frequency on the channel 1 is more than 5 times (namely, the preset threshold value is 5 times), if so, directly skipping the channel detection on the channel 1, and selecting the channel 2 for channel detection; otherwise, continuing to transmit the SRS3 to the base station a, and performing channel detection again on the channel 1 based on the received channel quality parameter 3.
Step 120: and determining an abnormal channel based on the obtained detection result corresponding to each channel.
Specifically, when step 120 is executed, the following steps may be adopted, but not limited to:
and the UE monitors the channel detection condition of each channel in real time, and when the channel detection of each channel is determined to be finished, based on the obtained transmitting power carried in the detection result corresponding to each channel, determines that the transmitting power corresponding to any one channel is different from the transmitting power corresponding to each other channel except the any one channel, and judges that the any one channel is an abnormal channel.
Preferably, the method for determining whether the channel detection of each channel is completed may be, but is not limited to, the following method:
the first mode is as follows: and judging by adopting a zone bit method, namely, the zone bit corresponding to the undetected channel is 0, and the zone bit corresponding to the detected channel is 1 (detected and successfully obtained a corresponding detection result) or 2 (detected but not obtained a corresponding detection result).
The second mode is as follows: and (4) judging by adopting a number checking method, namely deleting or ashing the icon corresponding to the detected channel, and determining the channel corresponding to the residual icon or the lightened icon as the undetected channel.
For example: the following description will be made by taking the above first embodiment as an example.
And the UE1 monitors the zone bit information of each channel in real time, and judges that the channel detection of each channel is finished when the zone bit information corresponding to each channel is set to 1 or 2.
The UE1 determines, according to the detection result corresponding to each channel, the transmission power carried in the detection result corresponding to any one channel, and determines that any one channel is an abnormal channel when the transmission power corresponding to the other channels is different from the transmission power corresponding to the other channels except the any one channel.
The UE1 displays the detection results of the above 8 channels to prompt: based on the detection results of the 8 channels, an abnormal channel is further determined, so that the accuracy of judging the abnormal channel is ensured, and the following steps are prompted: and correspondingly processing the abnormal channel.
The above embodiment is further described in detail by using a specific application scenario, and referring to fig. 2, in the embodiment of the present invention, a specific flow of the RRU channel detection method is as follows:

Step 203: when the UE1 determines that the RRU1 corresponds to 8 channels based on the number of channels corresponding to the RRU1 input by the user, automatically selects a channel 1 from the 8 channels corresponding to the RRU1 for channel detection, and sends a channel detection instruction 1 to the LMT.
Step 204: after receiving the channel detection instruction 1 sent by the UE1, the LMT determines that the corresponding BBU is the BBU1 based on the BBU identification information 1 carried in the channel detection instruction 1, and sends a channel closing instruction 1 to the BBU 1.

Step 206: after receiving the prompt information 1 sent by the BBU1, the UE1, when determining that all channels except channel 1 have been successfully closed, sends SRS2 to the base station a, and performs channel detection on channel 1 based on the received channel quality parameter 2 returned by the base station a based on SRS 2.
Step 207: the UE1 determines whether a corresponding detection result 1 is obtained within 10 seconds (i.e. the preset time range is 10 seconds), if yes, step 208 is executed; otherwise, step 209 is performed.
