Embodiment 1

[0051] The communication device connection method provided in this embodiment, such as Picture 1-1 As shown, the method includes:

[0052] 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;

[0053]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 i...

Embodiment 2

[0064] The communication device connection method provided in this embodiment, such as diagram 2-1 As shown, the method includes:

[0065] Step S201: The optical port rate conversion device automatically adapts to the optical port rate of the superior wireless device and establishes communication;

[0066] Step S202: Configure the output optical port rate of the optical port rate conversion device in the background;

[0067] 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.

[0068] Step S203: The optical port rate conversion device automatically adapts to the optical port rate of the superior wireless device and establishes communication.

[0069] Further, for the above step S202, automatic acqu...

Embodiment 3

[0072] This embodiment provides an optical port rate conversion device 300, such as Figure 3-1 As shown, it includes a matching connection module 301 and a rate conversion module 302: wherein, the matching connection module 301 is used to obtain 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 communicate with the upper-level The communication device establishes an upper-level communication link and establishes a lower-level communication link with the lower-level communication device; the rate conversion module 302 is used to convert the output optical port rate to the input optical port rate, and forward the optical port data of the upper-level communication device to the lower-level communication device.

[0073] Further, the matching connection module 301 is also used for: receiving the input optical port rate configure...

Abstract

The invention provides a communication device connection method and a system, and an optical port speed conversion device, and relates to the communication field. The optical port speed conversion device acquires output optical port speed of a superior communication device output optical port and input optical port speed of an inferior communication device input optical port, and establishes a superior communication link and an inferior communication link with a superior communication device and an inferior communication device respectively. The optical port speed conversion device converts the output optical port speed into input optical port speed and forwards optical port data of the superior communication device to the inferior communication device. Compared with prior art, the method, the system and the conversion device are characterized in that communication devices with different optical port speed are connected through the optical port conversion device, so the communication devices with different optical port speed can be linked; self-matching configuration of the optical port speed is achieved; compatibility between the communication devices can be improved; covering area of a base station is increased; flexibility of networking is improved; urban computer room selection difficulty level of operators is greatly reduced; and engineering construction and maintenance difficulty level is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication device connection method and system, and an optical port rate conversion device. Background technique [0002] 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). [0003] 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 ...
