本发明涉及通信领域，具体涉及一种通信设备连接方法和系统、光口速率转换设备。The invention relates to the communication field, in particular to a communication device connection method and system, and an optical port rate conversion device.
背景技术Background technique
长期演进(Long Term Evolution，LTE)无线通讯系统是由基带处理单元(Building Base band Unit，BBU)和射频拉远单元(Radio Remote Unit，RRU)构成的，BBU与RRU一起协作才能完成一个完整基站的功能，BBU和RRU之间通过公共射频接口(Common Public Radio Interface，CPRI)协议进行数据交互，数据传输的速率称为光口速率。CPRI协议规定物理层速率支持614.4/1228.8/2457.6/3072/4915.2/6144Mbps(兆位/秒)等一系列等级。The Long Term Evolution (LTE) wireless communication system is composed of a baseband processing unit (Building Base band Unit, BBU) and a radio remote unit (Radio Remote Unit, RRU). The BBU and the RRU work together to complete a complete base station The function of data exchange between the BBU and the RRU is through the common public radio interface (Common Public Radio Interface, CPRI) protocol, and the data transmission rate is called the optical port rate. The CPRI protocol stipulates that the physical layer rate supports a series of levels such as 614.4/1228.8/2457.6/3072/4915.2/6144Mbps (megabit/second).
由于每个型号RRU支持的光口速率不一致，BBU的光口需要配置不同的光口速率与RRU进行匹配，当BBU配置的光口速率与RRU支持速率不一致时，通信设备BBU与RRU无法正常建立链接，导致整个无线基站无法正常工作，进而导致目前大多数的LTE无线通讯系统的基站(Evolved Node B，eNodeB)只能BBU的一个光口控制管理一个对应的RRU，这种方式的局限性很多。Since the optical port rate supported by each model RRU is inconsistent, the optical port of the BBU needs to be configured with a different optical port rate to match the RRU. When the optical port rate configured by the BBU is inconsistent with the rate supported by the RRU, the communication device BBU and RRU cannot be established normally. link, resulting in the failure of the entire wireless base station to work normally, which in turn leads to the fact that the base stations (Evolved Node B, eNodeB) of most LTE wireless communication systems can only control and manage one corresponding RRU with one optical port of the BBU. This method has many limitations .

具体实施方式detailed description
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention. rather than all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
实施例一：Embodiment one:
本实施例提供的通信设备连接方法，如图1-1所示，该方法包括：The communication device connection method provided in this embodiment, as shown in Figure 1-1, includes:
S101：光口速率转换设备获取上级通信设备输出光口的输出光口速率，与输出光口速率进行光口速率匹配，建立上级通信链路；S101: The optical port rate conversion device obtains the output optical port rate of the output optical port of the upper-level communication device, performs optical port rate matching with the output optical port rate, and establishes an upper-level communication link;
在该步骤中，主要是为了与上级通信设备建立通信链路。这里的上级通信设备可以基带处理单元BBU或射频拉远单元RRU。例如，上级通信设备基带处理单元BBU的输出光口的输出光口速率为2G，那么就要获取该输出端口的协议格式，以其对应的速率以2.4576G的速率进行光口数据的接收，光口数据的格式是按照协议格式转换成串行数据。In this step, the main purpose is to establish a communication link with the upper-level communication device. The upper-level communication device here may be a baseband processing unit BBU or a remote radio unit RRU. For example, if the output optical port rate of the output optical port of the baseband processing unit BBU of the upper-level communication equipment is 2G, then the protocol format of the output port must be obtained, and the optical port data is received at the rate of 2.4576G at the corresponding rate. The format of the port data is converted into serial data according to the protocol format.
S102：光口速率转换设备获取下级通信设备输入光口的输入光口速率，将输出光口速率转换为输入光口速率；S102: The optical port rate conversion device obtains the input optical port rate of the input optical port of the lower-level communication device, and converts the output optical port rate to the input optical port rate;
在该步骤中，由于上级通信设备输出光口的输出光口速率与下级通信设备的输入光口速率不一致，光口速率转换设备需要与下级通信设备建立链路，在进行建链之前需要获取下级通信设备对应的输入光口的输入光口速率，能够将上级通信设备的输出光口速率转换为输入光口速率达到兼容的效果。这里的下级通信设备可以是射频拉远单元RRU。例如，下级通信设备射频拉远单元RRU的输入光口速率为3G，上级通信设备基带处理单元BBU的输出光口的输出光口速率为2G，为了保证能建立链路，将基带处理单元BBU的输出光口的输出光口速率2G转换为下级通信设备射频拉远单元RRU的输入光口速率3G。In this step, since the output optical port rate of the output optical port of the upper-level communication device is inconsistent with the input optical port rate of the lower-level communication device, the optical port rate conversion device needs to establish a link with the lower-level communication device. The input optical port rate of the input optical port corresponding to the communication device can convert the output optical port rate of the superior communication device to the input optical port rate to achieve a compatible effect. The lower-level communication device here may be a remote radio unit RRU. For example, the input optical port rate of the remote radio unit RRU of the lower-level communication equipment is 3G, and the output optical port rate of the output optical port of the baseband processing unit BBU of the upper-level communication equipment is 2G. In order to ensure that the link can be established, the baseband processing unit BBU The output optical port rate of 2G of the output optical port is converted to the input optical port rate of the remote radio unit RRU of the lower-level communication equipment 3G.
S103：光口速率转换设备与下级通信设备的输入光口连接，建立下级通信链路。S103: The optical port rate conversion device is connected to the input optical port of the lower-level communication device to establish a lower-level communication link.
在该步骤中，转换后的光口速率与下级通信设备的光口速率相同，两者的光口速率能够进行匹配，可以进行连接，并且建立链路。In this step, the converted optical port rate is the same as the optical port rate of the lower-level communication device, and the optical port rates of the two can be matched, and a connection can be made, and a link can be established.
在上述步骤S102中，光口速率转换设备获取下级通信设备输入光口的输入光口速率可以是所述光口速率转换设备接收用户通过后台管理配置的输入光口速率；即一种是通过用户去获取下级通信设备的输入光口速率，用户一般可以读取到下级通信设备的输入光口速率，将该输入光口速率通过后台管理界面进行输入配置。In the above step S102, the optical port rate conversion device obtains the input optical port rate of the input optical port of the lower-level communication device, which may be that the optical port rate conversion device receives the input optical port rate configured by the user through the background management; that is, one is through the user To obtain the input optical port rate of the lower-level communication device, the user can generally read the input optical port rate of the lower-level communication device, and input and configure the input optical port rate through the background management interface.
进一步，为了避免人为配置错误的光口速率带来的设备之间断链的问题，光口速率转换设备获取下级通信设备输入光口的输入光口速率还可以是光口速率转换设备自动获取下级通信设备的输入光口速率。具体的，光口速率转换设备自动获取下级通信设备的输入光口速率包括：光口速率转换设备获取下级通信设备输入光口的同相正交(In-phase/Quadrature，IQ)数据位宽、数据采样速率和有效天线数，根据IQ数据位宽、数据采样速率和有效天线数计算得到输入光口速率。具体IQ数据位宽包括发射IQ数据位宽和接收IQ数据位宽，具体有效天线数包括有效发射天线数和有效接收天线数。例如光口速率与参数的对应关系如下表所示，决定光口速率的因素有IQ数据位宽，数据采样速率，RRU配置的有效天线数(物理上有的天线不一定都使用)。每个参数配置的不一样根据CPRI协议可以计算出不同的光口速率，下表列举出3个示例：Further, in order to avoid the problem of link disconnection between devices caused by artificially configuring the wrong optical port rate, the optical port rate conversion device can obtain the input optical port rate of the input optical port of the lower-level communication device, and the optical port rate conversion device can automatically obtain the lower-level communication. The input optical port rate of the device. Specifically, the optical port rate conversion device automatically obtains the input optical port rate of the lower-level communication device, including: the optical port rate conversion device obtains the in-phase quadrature (In-phase/Quadrature, IQ) data bit width and data bit width of the input optical port of the lower-level communication device. Sampling rate and effective number of antennas. Calculate the input optical port rate according to the IQ data bit width, data sampling rate and effective number of antennas. The specific IQ data bit width includes the transmitting IQ data bit width and the receiving IQ data bit width, and the specific number of effective antennas includes the effective number of transmitting antennas and the effective number of receiving antennas. For example, the corresponding relationship between the optical port rate and parameters is shown in the following table. The factors that determine the optical port rate include the IQ data bit width, data sampling rate, and the number of effective antennas configured by the RRU (the physical antennas may not all be used). Different configurations of each parameter can calculate different optical port rates according to the CPRI protocol. The following table lists 3 examples:
在上述步骤S102中，将输出光口速率转换为输入光口速率包括：光口速率转换设备以输出光口速率接收上级通信设备输出光口的光口数据；光口速率转换设备根据输入光口速率对应的协议格式对接收到的光口数据进行转换处理；光口速率转换设备以输入光口速率对处理后的光口数据进行发送。例如,上级设备的光口速率配置完成之后，上级光口速率自适应模块的光口速率也就确定了，假设上级光口速率自适应模块的光口速率2G，那么光口就以2.4576G的速率进行光口数据的接收，光口数据的格式是按照协议格式(如图1-2所示)转换成串行数据进行发射，光口数据包含控制字和数据区，光口资源接收模块检测到控制字为一个光口数据的开始，将控制字和数据接收到光口资源存储模块进行存储，对于下级光口速率大于上级光口速率的情况，假设光口速率从2.4576G升到3.072G，存储模块就在接收到下一个光口控制字前按照3G的光口协议格式(如图1-3)作为一个单元进行存储，后级光口速率配置光口的光口速率确定为3G，光口资源发射模块将按照3.072的速率发送存储模块中的光口数据到下级设备。降速率和同速率的处理也是如此。对于上下级光口同速率的情况，也可以不经过光口资源存储模块，直接从光口资源接收模块发到光口资源发射模块到达下级设备。In the above step S102, converting the output optical port rate to the input optical port rate includes: the optical port rate conversion device receives the optical port data of the output optical port of the upper communication device at the output optical port rate; The protocol format corresponding to the rate converts the received optical port data; the optical port rate conversion device sends the processed optical port data at the input optical port rate. For example, after the optical port rate configuration of the upper-level equipment is completed, the optical port rate of the upper-level optical port rate adaptive module is determined. Assuming that the optical port rate of the upper-level optical port rate adaptive module is The optical port data is received at a high rate. The format of the optical port data is converted into serial data for transmission according to the protocol format (as shown in Figure 1-2). The optical port data includes control words and data areas. The optical port resource receiving module detects When the control word is an optical port data, the control word and data are received in the optical port resource storage module for storage. For the case where the rate of the lower-level optical port is greater than the rate of the upper-level optical port, it is assumed that the rate of the optical port increases from 2.4576G to 3.072G , the storage module stores as a unit according to the 3G optical port protocol format (as shown in Figure 1-3) before receiving the next optical port control word, and the optical port rate of the subsequent optical port rate configuration is determined as 3G, The optical port resource transmitting module will send the optical port data in the storage module to the lower-level device at a rate of 3.072. The same is true for down-rate and same-rate processing. For the situation that the upper and lower optical ports have the same rate, it can also be sent directly from the optical port resource receiving module to the optical port resource transmitting module to the lower device without going through the optical port resource storage module.
值得注意是，在本实例中是光口速率转换设备是先与上级通信设备建立通信链路，后与下级通信设备建立通信链路，还可以是先与下级通信设备建立通信链路，后与上级通信设备建立通信链路，应该理解为具体的建立通信链路的时序不构成限制，具体的可以根据具体情况而定，即光口速率转换设备获取上级通信设备输出光口的输出光口速率和下级通信设备输入光口的输入光口速率，并与上级通信设备建立上级通信链路和与下级通信设备建立下级通信链路。It is worth noting that in this example, the optical port rate conversion device first establishes a communication link with the upper-level communication device, and then establishes a communication link with the lower-level communication device. The upper-level communication equipment establishes a communication link. It should be understood that the specific timing of establishing a communication link does not constitute a limit. The specifics can be determined according to specific circumstances, that is, the optical port rate conversion equipment obtains the output optical port rate of the output optical port of the upper-level communication equipment. and the input optical port rate of the input optical port of the lower-level communication equipment, and establish the upper-level communication link with the upper-level communication equipment and the lower-level communication link with the lower-level communication equipment.
实施例二：Embodiment two:
本实施例提供的通信设备连接方法，如图2-1所示，该方法包括：The communication device connection method provided in this embodiment, as shown in Figure 2-1, includes:
步骤S201：光口速率转换装置的自动适应上级无线设备的光口速率并建立通信；Step S201: The optical port rate conversion device automatically adapts to the optical port rate of the superior wireless device and establishes communication;
步骤S202：后台配置光口速率转换装置的输出光口速率；Step S202: Configure the output optical port rate of the optical port rate conversion device in the background;
在该步骤中，具体的，直接透传后台配置的下级无线设备的光口速率给光口速率转换装置，光口速率转换装置将后台配置的光口速率设置为当前的光口速率。In this step, specifically, the optical port rate of the lower-level wireless equipment configured in the background is directly transparently transmitted to the optical port rate conversion device, and the optical port rate conversion device sets the optical port rate configured in the background as the current optical port rate.
步骤S203：光口速率转换装置的自动适应上级无线设备的光口速率并建立通信。Step S203: The optical port rate conversion device automatically adapts to the optical port rate of the superior wireless device and establishes communication.
进一步，对于上述步骤S202中，还可以采用自动获取，具体的建立通信后，光口速率转换装置计算下级无线设备光口速率并发送给，并将该佳光口速率设置为当前的光口速率。Further, for the above step S202, automatic acquisition can also be adopted. Specifically, after the communication is established, the optical port rate conversion device calculates the optical port rate of the lower-level wireless device and sends it to, and sets the optimal optical port rate as the current optical port rate .
采用本实施例的方法能用光口速率转换装置实现设备之间的光口速率转换，是一种比较实用和新颖的光口连接方式。特别是自动根据BBU下发的参数自动计算出下级无线设备的光口速率的功能减少人工配置光口速率错误带来的问题。如图2-2、2-3和2-4所示，其中，如图2-2和2-3中BBU代表上级通信设备，RRU代表下级通信设备。也可以上下级通信设备是同种设备，同为BBU或者RRU如图2-4所示。从图中可以看出为一个BBU的一个光口控制管理一个对应的RRU,应该理解为，在本实例中的光口速率转换装置的作用下，还可是实现一个BBU的一个光口控制管理多个对应的RRU，即通过光口速率转换装置与上级通信设备连接，并且与多个下级通信设备建立连接，将上级通信设备的光口速率分别转换为下级通信设备对应的光口速率。By adopting the method of this embodiment, the optical port rate conversion device can be used to realize the optical port rate conversion between devices, which is a relatively practical and novel optical port connection mode. In particular, the function of automatically calculating the optical port rate of the lower-level wireless device according to the parameters issued by the BBU reduces the problems caused by manual configuration of the optical port rate error. As shown in Figures 2-2, 2-3, and 2-4, BBU in Figures 2-2 and 2-3 represents upper-level communication equipment, and RRU represents lower-level communication equipment.
