It can be understood that, when the radio frequency unit is installed at the antenna end of the base station, the geographical position information of the antenna of the base station, such as pitch angle and horizontal azimuth angle, may be changed due to natural factors, such as wind, rain and the like, and the change of the position information of the antenna of the base station and the radio frequency unit may affect the coverage area of the base station signal, thereby affecting the communication between the terminal and the base station, so that it is necessary to acquire new first position information in real time, determine whether the radio frequency unit is in a pre-planned geographical position, and provide an effective data base for ensuring good communication between the terminal and the base station and maintaining the coverage area of the base station signal; when the new first position information is matched with any one of the second position information in the position information set to be matched, the radio frequency unit is still positioned at a preset optional installation position, a new radio frequency unit identifier is obtained again, and the new radio frequency unit identifier is resent to the radio frequency unit, so that the radio frequency unit reestablishes communication connection with the baseband processing unit according to the new radio frequency unit identifier; when the second position information corresponding to the new first position information cannot be matched in the position information set to be matched, the current radio frequency unit is not located at the optional installation position planned in advance, and communication connection cannot be established between the radio frequency unit and the baseband processing unit.

In addition, referring to fig. 6, in an embodiment, the baseband processing unit is connected to at least two radio frequency units, where the at least two radio frequency units are connected to the same communication port of the baseband processing unit, and the radio frequency units are first-stage radio frequency units in a radio frequency unit link, and the communication connection method of the embodiment further includes, but is not limited to, the following steps:

It is to be understood that, in the embodiment of the present application, the specific form that at least two radio frequency units are connected to the same communication port of the baseband processing unit is not limited, and as shown in fig. 16, one communication port of the baseband processing unit BBU1610 is connected to a plurality of radio frequency units 1620 through a packet forwarding network, including a first radio frequency unit AAU10, a second radio frequency unit AAU20, and a third radio frequency unit AAU30, where the AAU10, AAU20, and AAU30 are first radio frequency units of a first radio frequency unit link, a second radio frequency unit link, and a third radio frequency unit link, and the first radio frequency unit link has only one radio frequency unit AAU10; the second radio frequency unit link comprises an AAU20 and cascade radio frequency units AAU21 and AAU22; the third radio frequency unit link comprises an AAU30 and a cascade radio frequency unit AAU31; as shown in fig. 17, one communication port of the baseband processing unit BBU1710 may be connected to a plurality of radio frequency units 1730 (AAU 30, AAU40, and AAU 50) through a network connection device 1720 (e.g., a switch, etc.).

Because at least two radio frequency units are connected to the same communication port of the baseband processing unit, the topological relation among the radio frequency units connected to the same communication port is locally ambiguous, but is not simply in a cascading topological relation, and therefore, the mode of issuing and step-by-step transmitting the radio frequency unit identifiers in a mode similar to a control word is not applicable any more; in the embodiment of the present application, referring to the description of the embodiment of fig. 1, in the working stage of the radio frequency unit, each radio frequency unit connected to the same communication interface of the baseband processing unit sends first location information to the baseband processing unit, so as to request the baseband processing unit to allocate a radio frequency unit identifier, and establish communication connection with the baseband processing unit according to the radio frequency unit identifier; because the first position information characterizes the installation position of the current radio frequency unit, when the first position information is matched with any one of the second position information in the position information set to be matched, the radio frequency unit is determined to be installed at the optional installation position planned in advance in the network planning stage, the radio frequency unit is successfully positioned, the radio frequency unit identification corresponding to the second position information is acquired, and the radio frequency unit information is fed back to the radio frequency unit, so that the radio frequency unit can establish communication connection with the baseband processing unit according to the radio frequency unit identification, the physical connection relation between devices can be not relied on any more, and under the condition that the topology of the radio frequency unit in an Ethernet transmission network is fuzzy, the radio frequency unit with the same type in the same area has identification capability.

In addition, in the embodiment, the radio frequency unit can also request the radio frequency unit identification from the baseband processing unit through the identification data such as the radio frequency unit model number, the asset bar code number and the like, but the identification data has the defect of low distinguishing degree, and in the process that the radio frequency unit is matched with the preset radio frequency unit planned in the baseband processing unit through the identification data, the information of the labor survey is required to be strictly checked, the consistency with the network management configuration information is ensured, and larger network construction and maintenance cost can be brought; therefore, the positioning of the radio frequency unit is realized by matching the first position information with the second position information planned in advance, the complex asset sequence code is not required to be recorded by construction and maintenance personnel, the correctness of the corresponding relation between the asset sequence code of each device and the configuration is not required to be checked in the system, and the construction cost of the network construction stage and the maintenance cost of network maintenance can be greatly planned.
