In a 5G NR system, the cell coverage is smaller than that of 4G, more base stations are built when operators build networks, and the construction cost is high, so that the co-building sharing of the base stations among different operators has great advantages, and the network construction cost of the operators can be obviously reduced. Therefore, the co-construction sharing mode can improve the problems of repeated construction, high cost, high energy consumption and the like of the base station, improves the utilization efficiency of resources, and rapidly forms leading network capability to promote the development of 5G industry in high quality, health and green.

1. the air interface resources are limited and are unevenly distributed. Although the network cost is reduced through the co-building sharing, as the air interface resources are limited, the reasonable division of the air interface resources is not achieved, and users among different operators can compete for the air interface resources, so that the conflict among the operators of the co-building sharing is directly caused.

2. Operator user satisfaction decreases. The wireless base station network cannot be fully utilized, operators cannot schedule users in time, service rate can be rapidly reduced or even dropped, the needs of users of each operator cannot be effectively guaranteed, and experience of the users can be reduced.

In summary, the existing 5G base station co-building sharing system is not perfect enough, and each operator cannot operate efficiently and reasonably meet the user requirements.

Principle and advantage:

1. for a non-co-established shared base station cell, the base station can allocate air interface frequency domain resources according to service priority scheduling, so that different users can be ensured to reasonably use the 5G network. However, for the co-established shared base station cell, users under each operator compete for using the air interface frequency domain resources, but because uniform resource allocation management cannot be performed, users of different operators can mutually influence, so that normal use of the 5G network by the users is influenced, and user experience is poor. For the sake of easy understanding, the description will be given by taking the configuration of 2 operators in the cell of the radio base station as an example, and the number of operators can be extended. By configuring exclusive, preferential and shared resources of the operators 1 and 2 in the network management, the allocable resources of the users under each operator are controlled, and when the number of users under the operators 1 and 2 and the service of the users have great difference, the cell shared resources can be allocated for the users under the operators 1, so that the purpose of fully utilizing the cell air interface resources is achieved, meanwhile, the exclusive resources are reserved for the operators 2, and the service and the user experience of the users under the operators 2 are ensured. When the number of users under the operator 2 increases, the priority resource can be preferentially used when the dedicated resource is insufficient, then the shared resource can be used together with the users under the operator 1, and the service of the users under the two operators is simultaneously ensured through algorithm control.

2. According to the scheme, different configuration parameters are configured according to different scenes to control the base station to allocate resources for users, the algorithm is designed to optimize, a certain proportion of dedicated resources are set for each operator cell while the frequency domain resources of the wireless base station cell are fully utilized, the service of the users under the different operator cells is guaranteed, the network construction cost of the operators is reduced, and the perception of the users is guaranteed. The application optimizes through software algorithm, does not increase hardware cost, reduces network construction cost of operators, and improves the utilization rate of air interface resources of the base station.

s002, otherwise, if intra-cell operator Pi exclusive remaining resource > =0,

the number of available PRBs is max (0, min (min (operator Pi exclusive + priority, operator Pi exclusive + exclusive remaining resources), max resources of operator Pi) -operator Pi occupied resources;
