Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for returning radio frequency channel detection data.
Background
The monitoring of the antenna system of the indoor distribution system can not monitor whether the antenna system works normally or not because the antenna system does not have a feedback channel. In order to solve the problem, some manufacturers develop monitoring systems based on Radio Frequency Identification (RFID) technology, and the systems install an RFID tag at the position of an antenna, and install an RFID card reader at the Radio Remote Unit (RRU) side of a base station, where the card reader initiates an inquiry operation to the RFID tag through a Radio Frequency channel.
At present, when data read by an RFID card reader is returned through a network cable, the network cable needs to be laid separately, so that additional equipment is needed, and the cost is increased; when data read by the RFID card reader is returned through the mobile network, a mobile modem and a Subscriber Identity Module (SIM) card need to be installed on the RFID card reader side, which increases the cost of the device. It can be seen that when the RFID card reader returns read data through a mobile network or through a separately laid network cable, an additional device is required in any way.

If the radio frequency channel is working normally, the RFID card reader will receive the feedback data of the RFID tag, and after receiving the feedback data, fig. 1 shows that the RFID card reader transmits the detection data to the server through the mobile network, but it is also possible to omit the method shown in fig. 1, for example, a separate network cable is laid between the RFID card reader and the server, the RFID card reader returns the feedback data to the server through the network cable, and the server can monitor the working state after acquiring the data of the radio frequency channel through the method.

Based on the architecture shown in fig. 2, fig. 3 is a schematic flow chart of a backhaul method for detecting data by using a radio frequency channel according to an embodiment of the present invention. The process may include the steps of:
step 301: and the remote radio unit sends a request message for acquiring the radio frequency channel detection data of the distributed base station to the detection equipment through the data line.
In this step, the detection device has the radio frequency channel detection data that the radio frequency remote unit wants to acquire, and specifically, the detection device can acquire the radio frequency channel detection data according to the strength of the signal sent by the radio frequency identification module.
In this step, the request message sent by the remote radio unit may be used to instruct to acquire the detection data of all the radio frequency channels, or to acquire the detection data of the specified radio frequency channel. Specifically, the request message carries an identifier of a radio frequency identification module or an identifier of an antenna of the distributed base station, so as to instruct to acquire detection data of radio frequency channels corresponding to the identifiers.
Step 302: and the detection equipment returns a response message to the radio remote unit through the data line according to the request message, wherein the response message carries the radio frequency channel detection data of the distributed base station requested to be acquired.
In the step, the response message carries radio frequency channel detection data, in a first mode, the radio frequency channel detection data carries an identifier of an antenna of the distributed base station and a value representing an actual path loss of the radio frequency channel, and in a second mode, the radio frequency channel detection data carries an identifier of the radio frequency identification module and a value representing an actual path loss of the radio frequency channel.
Specifically, the specific process of the first mode may include:
taking the architecture diagram shown in fig. 2 as an example, the RFID card reader initiates an inquiry request to the RFID tag as a detection device, receives radio frequency channel detection data fed back by the RFID tag, where the radio frequency channel detection data carries an identifier of the RFID tag, and after receiving the identifier of the RFID tag, the RFID card reader determines an antenna of a distributed base station corresponding to the RFID tag according to the identifier of the RFID tag stored in the RFID card reader and an identifier of an antenna of a distributed base station corresponding to the RFID tag, and then carries the identifier of the antenna of the distributed base station in a response message to send the response message to the remote radio unit.
The specific process of the second mode can comprise the following steps:
the method comprises the steps that an RFID card reader serving as detection equipment initiates an inquiry request to a radio frequency identification module RFID label, an identification of the RFID label is carried in radio frequency channel detection data fed back by the RFID label, the detection data is carried in a response message and sent to a radio remote unit after the radio frequency channel detection data carrying the identification of the RFID label is received by the RFID card reader, and after the radio remote unit receives the identification of the RFID label, the antenna of a distributed base station corresponding to the RFID identification is determined according to the identification of the RFID label stored in the radio remote unit and the identification of the distributed base station corresponding to the identification.
When the response message is returned, the detection data is returned in the form of a { number of the RFID tag, an actual path loss value } data pair, and specifically, all the radio frequency channel detection data or the detection data of the designated radio frequency channel carried in the returned response message may be defined as the following structure:
specifically, the data structure of the number of the RFID tag and the actual path loss value of the RFID tag may be defined as the following structure:
the RFID label number is a character string type and is used for distinguishing each RFID;
the actual path loss value, an 8-bit signed integer in dB, is used to describe the actual value path loss value returned from the RFID tag to the RFID reader.
Optionally, all the radio frequency channel detection data carried in the returned response message or the detection data of the specified radio frequency channel may also carry the following parameters:
the RFID card readers are numbered and the character string types are used for distinguishing each RFID card reader;
RRU numbers and character string types are used for distinguishing each RRU;
an installation position, a character string type, for distinguishing a position of an antenna where the RFID tag is installed;
a reference path loss value, namely an 8-bit signed integer with the unit of dB, is used for describing a theoretical path loss value from each card reader to the RFID label, and the value can be obtained from the room division planning data;
step 303: and the radio remote unit sends the acquired radio frequency channel detection data to a server through a baseband processing unit of the distributed base station.
Further, if the detection device determines that the path loss of the radio frequency channel exceeds the set threshold according to the radio frequency channel detection data, the detection device sends alarm information for the radio frequency channel to the remote radio unit. Specifically, the detection device is provided with a path loss threshold and a reference path loss value, and if a difference value obtained by subtracting the reference path loss value from the actual path loss value is greater than the path loss threshold, the detection device sends alarm information for the radio frequency channel to the remote radio unit, where the alarm information is used to indicate that the path loss value of the radio frequency channel is large and the signal quality of the radio frequency channel is poor, and the alarm information may be sent in a response message or may be sent separately.
Of course, after receiving the radio frequency channel detection data returned by the wireless identification module, the detection device may not make the above determination, but directly send the radio frequency channel detection data to the remote radio unit, and the remote radio unit determines whether the radio frequency channel generates an alarm according to the same method; of course, the detection device and the remote radio unit may be both responsible for sending the radio channel detection data to the server instead of making the above determination, and the server determines whether the radio channel generates an alarm, which is not specifically limited in the embodiment of the present invention.
It can be seen that, in the solution provided in the embodiment of the present invention, the radio frequency channel detection device and the radio remote unit are connected by the data line, so that the radio frequency channel detection data directly returns to the radio remote unit through the data line, and the radio remote unit sends the detection data to the server, thereby overcoming the defect that an additional device is required when the radio frequency channel detection data is returned in the prior art, and implementing data return by using the existing device.
Further, the response message sent by the detection device may also carry information of the intermediate device existing in the radio frequency channel, and specifically, the information of the intermediate device may be defined as the following structure: the intermediate device, the character string type, is used to distinguish the information of the power divider connected between the combiner and the antenna, and the server can create the topological graph of the radio frequency channel of the distributed base station according to the information of the intermediate device after receiving the information of the intermediate device. The information of the intermediate device may also be sent by other ways without being carried in the response message, which is not specifically limited in the embodiment of the present invention. As shown in fig. 4, the topology map is drawn by the server according to the information of the intermediate device carried in the response message.
Referring to fig. 4, a topology diagram of radio frequency channels of a distributed base station is drawn by a server according to information of an intermediate device according to an embodiment of the present invention.
