A downlink resource block reservation method and device

Abstract

Embodiments of the present invention provide a method and device for reserving downlink resource blocks, which relate to the field of communication technology and are applied to access network equipment that configures separate carriers for different types of services of each operator, which can reasonably allocate downlink resource blocks and improve resource utilization. The method includes: acquiring the service guarantee parameters of each service to be accessed in the target service set; the target service set is composed of all services to be accessed belonging to the same carrier configured by the access network equipment; according to the service guarantee parameters of the services to be accessed, Determine the downlink resource block RB demand value of the current unit time of the service to be accessed; the sum of the downlink RB demand values ​​of all services to be accessed in the target service set at the current unit time is greater than the rated downlink RB of the carrier corresponding to the target service set In the case of the value of , according to the downlink RB demand value of the service to be accessed in the current unit time and the Qos level parameter, the downlink RB is reserved for the service to be accessed in the target service set.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for reserving downlink resource blocks. Background technique [0002] With the continuous evolution of the network, the demand for diverse industry applications has exploded. Network requirements for industry users have become an important deployment requirement for 5G. As a key base station configuration technology for 5G, hard slicing technology (reserving RB resources) greatly ensures the service quality and security of industry users, and has become the main method of current campus deployment or specific area deployment. In addition, since the 5G equipment (5G base station) uses a variety of antenna equipment such as 192 antennas, and the frequency band used by the 5G equipment is 3.5GHz, the coverage range is significantly smaller than that of the equipment in the frequency band of 2GHz and below, which will lead to The number of sites (the n...

Problems solved by technology

[0003] After the co-construction and sharing of base stations, it is generally necessary to use the same equipment to meet the needs of multiple operators. However, the shared base stations after co-construction are currently not supporting the public network services (2C services) and private network services (2B services) of multiple operators. business) at the same time, the method of determining the reserved value of RB seriously affects the utilization of resources
