Description

Method and device for controlling RRU to access base station
Technical Field
The present invention relates to mobile communication technology, and particularly to a method and apparatus for controlling a Radio Remote Unit (RRU) to access a base station via a license.
Background
As is well known, in a new generation of mobile communication network, a base station in the mobile communication network is composed of a base station processing unit (BBU) and a Radio Remote Unit (RRU). The RRU is connected to the BBU through an RRU interface on the BBU (for convenience of description, the RRU interface on the BBU is hereinafter referred to as an RRU interface), and generally, the RRU interface is an optical interface and is located on an RRU interface board. RRUs can be cascaded in a RRU chain or ring. One end of the RRU chain is an RRU interface, and the other end of the RRU chain is an RRU; both ends of the RRU ring are RRU interfaces. The RRU networking structure is a structure corresponding to one or more RRUs after being cascaded and is divided into a star networking structure, a chain networking structure, a ring networking structure and a ring + chain networking structure. Obviously, the RRU chains and the RRU rings correspond to a chain type networking structure and a ring type networking structure, respectively, the RRU chains including one RRU correspond to a star type networking structure, and the mixed structure of the RRU chains and the RRU rings corresponds to a ring + chain networking structure. Fig. 1 is a schematic diagram of an RRU networking structure of each base station, where 101 is an RRU interface board, 102 is an RRU interface, 103 is a star networking structure, 104 is a chain networking structure, 105 is a ring networking structure, and 106 is a ring + chain networking structure. As shown in fig. 1, it is understood that the star networking structure, the ring networking structure and the ring + chain networking structure can be regarded as a special case of the chain networking structure.
Currently, a base station supports that, according to obtained topology data configured by a network manager, an RRU topology of the base station, that is, a set of RRU networking structures of RRU interfaces on the base station, is changed correspondingly. When the RRU topology of the base station cannot be configured according to the obtained RRU topology data configured by the network management, the number of the RRUs accessed to the base station is controlled according to the license, so that the controllability of the base station is influenced, and the market demand cannot be better met.

step 201: a first sequence, a license and a first authorization strategy of an RRU interface are preset.
The first order may be an order of numbers of the RRU interfaces from large to small or from small to large. Here, the number of the RRU interface may be generated according to the number of the RRU interface board where the RRU interface is located and the number of the RRU interface on the interface board.

How to obtain RRU topology data configured by the network management belongs to a conventional technical means of a person skilled in the art, and is not described herein again.
When the license limits the total number of RRUs that can be authorized, the first authorization policy may include: and when the number of the remaining authorized RRUs is greater than or equal to 1, the current RRU is authorized.
When the license limits the total number of RRUs that can be authorized, before determining in this step, the method of the present invention may further include: and setting the initial value of the number of the remaining authorized RRUs as the total number of the RRUs limited by the license.
When the license limits the total number of RRUs that can be authorized, after the determination in this step, the method of the present invention may further include: and if the current RRU is authorized, reducing the number of the remaining authorized RRUs by 1.
When the license limits the total number of RRUs and the total number of RRU rings that can be authorized, the first authorization policy may include:
1) when the RRU networking structure on the current RRU interface is an RRU ring, the number of the remaining authorized RRU rings is greater than or equal to 1, and the number of the remaining authorized RRUs is greater than or equal to 1, the current RRU is authorized;
2) when the RRU networking structure on the current RRU interface is not an RRU ring and the number of remaining authorized RRUs is greater than or equal to 1, the current RRU is authorized.
When the license limits the total number of RRUs and the total number of RRU rings that can be authorized, before determining in this step, the method of the present invention may further include: setting the initial value of the residual authorized RRU number and the initial value of the residual authorized RRU ring number as the RRU total number and the RRU ring total number limited by the license respectively.
When the license limits the total number of RRUs and the total number of RRU rings that can be authorized, after the determination in this step, the method of the present invention may further include: when the current RRU is authorized, subtracting 1 from the number of the remaining authorized RRUs; when the networking structure of the RRU on the current RRU interface is an RRU ring and all RRUs on the RRU interface are authorized, the number of the remaining authorized RRU rings is reduced by 1.

The specific implementation of the RRU topology for configuring the base station according to the RRU topology data belongs to the technical means commonly used by those skilled in the art, and is not described herein again.
It should be noted that:
1) determining whether the RRU configuration on the current RRU interface can be authorized is carried out according to a preset first sequence, so that the RRU topology data after license authorization are the same when the RRU topology data configured by the network management are the same.
2) Since it is only necessary to determine whether the network management configuration RRU on the RRU interface can be authorized for any one of the two RRU interfaces to which the RRU ring belongs, it is determined in this step whether the network management configuration RRU on the current RRU interface can be authorized, and this is performed for an RRU interface that does not include an authorized RRU.

It should be noted that, for example, when the base station works for the first time, the current RRU topology data is all-zero data, and when the current RRU topology data is all-zero data, the calculated update weight of each RRU interface is zero.
Through the above calculation formula, it can be easily seen that the maximum value of the update weight is 1, and the larger the update weight is, the smaller the modification of the RRU networking structure on the corresponding RRU interface is if the RRU topology of the base station is configured according to the obtained RRU topology data configured by the network manager.
Step 302: and sequencing the RRU interfaces according to the ascending weight of the RRU interfaces.
Where the steps may be implemented using a sorting method familiar to those skilled in the art, such as bubble sorting.
When the RRU interfaces are sequenced, the RRU interfaces with the same updating weight are sequenced according to the sequence of the corresponding RRU interfaces in the first sequence. Therefore, the RRU interfaces with the same updated weights and the same serial numbers are ensured to have the same sequence after two or more times of sequencing, namely the sequencing result is ensured to be stable.
