Description
技术领域technical field
本发明涉及无线电通信技术，尤指一种配置天线设备的方法。The invention relates to radio communication technology, in particular to a method for configuring antenna equipment.
背景技术Background technique
在无线通信系统中，支持天线接口标准组织(Antenna Interface StandardsGroup，AISG)协议的电调天线或塔顶放大设备，这里统称为天线设备(Antenna Line Device，ALD)，正受到越来越广泛的应用。在ALD设备出厂时，制造商都会为每个ALD设备配置类似网卡的介质访问控制(MediumAccess Control，MAC)地址的唯一设备标识(Unique ID)，用来标示该设备。在实际应用中，当手工完成在基站电线口上安装ALD设备后，使用维护台向基站发送包括增加ALD设备、配置天线倾角等命令在内的配置ALD设备命令时，同时必须输入标示该ALD设备的Unique ID作为参数，用来向基站指示操作的ALD设备。因此，在增加ALD设备以及对ALD设备进行其他配置时，工作人员往往需要记录或记忆由最多19个字节组成的Unique ID，记录并输入这一长串数字，对工作人员来说是难以接受、容易出错的，降低了工作人员配置ALD设备的工作效率。而且，在大规模建网时，对于ALD设备的许多配置项都是相同的，但使用Unique ID作为配置项时，由于每个ALD设备的Unique ID不相同，因此对不同的ALD设备必须分别输入各自的Unique ID，以及其他配置项，不利于大批建站时的操作。In wireless communication systems, electronically adjustable antennas or tower top amplification devices that support the Antenna Interface Standards Group (AISG) protocol, collectively referred to here as Antenna Line Devices (ALD), are being used more and more widely. . When the ALD device leaves the factory, the manufacturer will configure a unique device identification (Unique ID) similar to the Media Access Control (MAC) address of the network card for each ALD device to identify the device. In practical applications, after manually installing the ALD device on the cable port of the base station, when using the maintenance console to send commands for configuring the ALD device to the base station, including commands such as adding ALD devices and configuring antenna tilt angles, the ALD device must be entered at the same time. Unique ID is used as a parameter to indicate the operating ALD device to the base station. Therefore, when adding ALD equipment and performing other configurations on ALD equipment, the staff often need to record or memorize the Unique ID consisting of up to 19 bytes. It is unacceptable for the staff to record and enter this long string of numbers. , Error-prone, reducing the work efficiency of staff to configure ALD equipment. Moreover, during large-scale network construction, many configuration items of ALD devices are the same, but when using Unique ID as a configuration item, since the Unique ID of each ALD device is different, it must be entered separately for different ALD devices. Their respective Unique IDs, as well as other configuration items, are not conducive to the operation of building a large number of sites.

具体实施方式Detailed ways
本发明的核心思想是：在配置ALD设备时，输入该ALD设备所在天线口信息和该ALD设备的设备类型信息，通过接收包含天线口信息的配置ALD设备的命令，从命令中获得当前需要配置ALD设备的天线口信息以及设备类型信息，并且根据获得的天线口信息以及设备类型信息得到当前需要配置的ALD设备的Unique ID，最后根据得到的Unique ID执行配置ALD设备的操作。The core idea of the present invention is: when configuring the ALD device, input the information of the antenna port where the ALD device is located and the device type information of the ALD device, and obtain the current required configuration from the command by receiving the command for configuring the ALD device including the antenna port information. The antenna port information and device type information of the ALD device, and according to the obtained antenna port information and device type information, obtain the Unique ID of the ALD device that needs to be configured currently, and finally perform the operation of configuring the ALD device according to the obtained Unique ID.
本发明所述的方法仅适用于在天线口上安装不同类型的ALD设备，即对于同种类型的设备只能在天线口上安装一个，例如可以在天线口上安装一个电调天线、或一个塔顶放大设备、或一个电调天线和一个塔顶放大设备；不能在天线口上安装两个电调天线、或两个塔顶放大设备、或二个电调天线和一个塔顶放大设备。这里所述的安装是指，将ALD设备安装在基站的天线口上，并没有执行对安装在天线口上的ALD设备的配置工作。以下通过两个较佳实施例对本发明所述的方法进行更为详细的说明。The method described in the present invention is only suitable for installing different types of ALD equipment on the antenna port, that is, only one device of the same type can be installed on the antenna port, for example, an electric adjustable antenna or a tower top amplifier can be installed on the antenna port equipment, or one electronically adjustable antenna and one tower-mounted amplifier; two electrically-regulated antennas, or two tower-mounted amplifiers, or two electrically-regulated antennas and one tower-mounted amplifier cannot be installed on the antenna port. The installation mentioned here means that the ALD device is installed on the antenna port of the base station, and the configuration of the ALD device installed on the antenna port is not performed. The method described in the present invention will be described in more detail through two preferred embodiments below.
第一较佳实施例first preferred embodiment
当用户需要配置ALD设备之前，记录该ALD设备的天线口信息和设备类型信息，在发送配置命令时，将命令中原来携带的参数Unique ID改为ALD设备所在天线口信息和ALD设备的类型信息。Before the user needs to configure the ALD device, record the antenna port information and device type information of the ALD device, and when sending the configuration command, change the original parameter Unique ID in the command to the antenna port information of the ALD device and the type information of the ALD device .
先以在基站上增加ALD设备为例，说明具体的配置过程。当用户手工在基站天线口上完成安装ALD设备后，使用维护台向基站发送增加ALD设备命令时，将命令中原来携带的参数Unique ID改为ALD设备所在天线口信息和ALD设备的类型信息，并执行如图1所示的步骤。维护台和基站之间通过有线或无线的方式进行通信。Take adding an ALD device on the base station as an example to illustrate the specific configuration process. After the user manually installs the ALD device on the antenna port of the base station, and uses the maintenance console to send the command to add the ALD device to the base station, the original parameter Unique ID carried in the command is changed to the information of the antenna port where the ALD device is located and the type information of the ALD device, and Perform the steps shown in Figure 1. The communication between the maintenance station and the base station is carried out in a wired or wireless manner.
步骤101～102：基站收到用户通过维护台传来的增加ALD设备命令后，从命令中读出ALD设备所在天线口信息以及此次操作的ALD设备的设备类型信息。Steps 101-102: After receiving the command to add an ALD device from the user through the maintenance station, the base station reads the antenna port information of the ALD device and the device type information of the ALD device being operated from the command.
步骤103：使用AISG协议中的扫描(SCAN)命令扫描该天线口，扫描结果返回该天线口上已经安装了的ALD设备的Unique ID以及对应的设备类型信息。在扫描返回的结果中，查找到与增加ALD设备命令中携带的设备类型信息对应的Unique ID，则该Unique ID即为当前所要增加的ALD设备所对应的Unique ID。Step 103: Use the scan (SCAN) command in the AISG protocol to scan the antenna port, and the scan result returns the Unique ID of the ALD device installed on the antenna port and the corresponding device type information. In the results returned by the scan, if the Unique ID corresponding to the device type information carried in the command to add an ALD device is found, the Unique ID is the Unique ID corresponding to the ALD device to be added currently.
例如，如果在天线口上安装了一个电调天线和一个塔顶放大设备，当前要增加的设备为电调天线。此时，使用AISG协议中的SCAN命令扫描该天线口，则返回这两个设备的Unique ID以及对应的设备类型信息。由于当前要增加的ALD设备为电调天线，因此根据接收到的增加电调天线命令中携带的设备类型信息，在扫描返回的结果中查找得到与该设备类型对应的Unique ID，则该Unique ID即为当前所要增加的电调天线所对应的UniqueID。For example, if an electronically adjustable antenna and a tower top amplification device are installed on the antenna port, the current device to be added is the electronically adjustable antenna. At this time, use the SCAN command in the AISG protocol to scan the antenna port, and return the Unique ID of the two devices and the corresponding device type information. Since the current ALD device to be added is an electronically adjustable antenna, according to the device type information carried in the received command to add an electronically adjustable antenna, the Unique ID corresponding to the device type is found in the results returned by the scan, and the Unique ID It is the UniqueID corresponding to the electric adjustable antenna to be added currently.
步骤104：基站根据获得的ALD设备的Unique ID，为ALD设备配置高级数据链路控制(High-level Data Link Control，HDLC)地址，建立基站与ALD设备之间的链路，并根据基站数据中心保存的参数，初始化ALD设备，使ALD设备正常工作。Step 104: The base station configures an advanced data link control (High-level Data Link Control, HDLC) address for the ALD device according to the obtained Unique ID of the ALD device, establishes a link between the base station and the ALD device, and according to the base station data center Save the parameters, initialize the ALD device, and make the ALD device work normally.
如图1所示的操作同样适用于其他配置ALD设备的操作，如配置天线倾角、或天线校准、或查询天线倾角、或配置塔顶放大设备工作模式等。The operations shown in Figure 1 are also applicable to other operations for configuring the ALD device, such as configuring the antenna inclination, or antenna calibration, or querying the antenna inclination, or configuring the working mode of the tower top amplification device, etc.
但在配置天线倾角或配置塔顶放大设备工作模式等命令时，由于这类命令已经隐含了操作对象的设备类型信息，即基站设备在读到这类命令后，就会根据该命令的内容得到所针对设备的设备类型信息，因此在向维护台输入命令时不用携带该命令所针对ALD设备的设备类型信息，只需携带ALD设备所在的天线口信息即可。现以配置天线倾角为例，实现流程如图2所示，具体步骤如下：However, when configuring commands such as antenna inclination angle or tower top amplification equipment operating mode, since such commands already imply the device type information of the operating object, that is, after the base station device reads such commands, it will obtain the The device type information of the target device. Therefore, when entering a command to the maintenance station, it is not necessary to carry the device type information of the ALD device targeted by the command, but only the antenna port information where the ALD device is located. Now take configuring the antenna inclination angle as an example. The implementation process is shown in Figure 2. The specific steps are as follows:
步骤201～202：基站收到用户通过维护台传来的配置天线倾角的命令后，从命令中读出ALD设备所在天线口信息。Steps 201-202: After the base station receives the command to configure the antenna inclination angle from the user through the maintenance station, it reads the information of the antenna port where the ALD device is located from the command.
步骤203：使用AISG协议中的SCAN命令扫描该天线口，扫描结果返回该天线口上已经安装的ALD设备的Unique ID以及对应的设备类型信息，然后再根据基站设备读到该命令后得到的设备类型信息，在扫描返回的结果中查找得到与该设备类型信息对应的Unique ID，则该Unique ID为当前配置天线倾角所对应的ALD设备的Unique ID。Step 203: Use the SCAN command in the AISG protocol to scan the antenna port, and the scan result returns the Unique ID of the ALD device installed on the antenna port and the corresponding device type information, and then read the device type obtained after reading the command from the base station device Information, find the Unique ID corresponding to the device type information in the results returned by the scan, then the Unique ID is the Unique ID of the ALD device corresponding to the currently configured antenna inclination angle.
步骤204：根据获得电调天线的Unique ID，配置天线倾角。Step 204: Configure the antenna inclination according to the obtained Unique ID of the electronically adjustable antenna.
第二较佳实施例Second preferred embodiment
在基站上安装完ALD设备后，首先按照如图1所示的过程增加ALD设备，但在执行步骤103时，在获得Unique ID之后，同时建立Unique ID与天线口信息和设备类型信息的对应关系。After installing the ALD device on the base station, first add the ALD device according to the process shown in Figure 1, but when executing step 103, after obtaining the Unique ID, establish the corresponding relationship between the Unique ID and the antenna port information and device type information at the same time .
在这种情况下，也可以按照如下方法对ALD设备进行其他配置操作。现以配置天线倾角为例说明，用户发送配置天线倾角命令时，将现有技术中携带的参数Unique ID改为天线口信息和设备类型信息，按照以下步骤进行，具体过程如图3所示：In this case, other configuration operations on the ALD device can also be performed as follows. Let’s take configuring the antenna tilt as an example. When the user sends the command to configure the antenna tilt, change the parameter Unique ID carried in the prior art to the antenna port information and device type information, and follow the steps below. The specific process is shown in Figure 3:
步骤301～302：基站收到配置天线倾角命令后，从配置天线倾角命令中获得天线口信息和设备类型信息。Steps 301-302: After receiving the antenna tilt configuration command, the base station obtains antenna port information and device type information from the antenna tilt configuration command.
步骤303：基站收到配置天线倾角的命令后，根据命令中的天线口信息以及设备类型信息，查找天线口信息和设备类型信息与Unique ID的对应关系，得到该设备的Unique ID。Step 303: After receiving the command to configure the antenna tilt angle, the base station searches for the correspondence between the antenna port information and device type information and the Unique ID according to the antenna port information and device type information in the command, and obtains the Unique ID of the device.
当配置命令中隐含有设备类型信息时，本步骤也可按照以下方式进行。例如，基站在收到配置天线倾角命令后，根据配置命令所针对的设备类型，确定设备类型信息，再根据从配置天线倾角命令中获得的天线口信息，查找天线口信息和设备类型信息与Unique ID的对应关系，得到该设备的UniqueID。在这种情况下，在发送配置命令的时候，则只需要将现有技术中携带的参数Unique ID改为天线口信息，基站也只从配置命令中获得天线口信息即可。When the device type information is implied in the configuration command, this step can also be performed in the following manner. For example, after receiving the command to configure the antenna tilt angle, the base station determines the device type information according to the device type targeted by the configuration command, and then searches for the antenna port information and device type information according to the antenna port information obtained from the command to configure the antenna tilt angle. ID correspondence to get the UniqueID of the device. In this case, when sending the configuration command, it is only necessary to change the parameter Unique ID carried in the prior art to the antenna port information, and the base station can only obtain the antenna port information from the configuration command.
步骤304：根据电调天线的Unique ID配置天线倾角。Step 304: Configure the antenna inclination according to the Unique ID of the electronically adjustable antenna.
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
