Embodiment approach

[0061] As a preferred embodiment, the edge average path loss value is determined according to the following formula:

[0062] Among them, w k =|C k | / K,

[0063] f j k = g j ( k ) + u · max { 0 , g j ( k ) - g j . max } , ∀ j = 1,2 , . . . , C k , ∀ k = 1,2 , . . . , M , u represent...

Abstract

The invention discloses a service base station determining method, a service base station determining device, and a base station. The method is characterized in that a central average path loss value of N base stations of an ultra dense networkUDN and a central user and an edge average path loss value of N base stations and an edge user. The central user is the user in the predetermined service range of N base stations, and the edge user is the user out of the predetermined service range of N base stations. The service base station can be selected from N base stations according to the central average path loss value and the edge average path loss value. According to the invention, the problem of the prior art of the overlarge system interference caused by the unreasonable distribution of the base stations of the ultra dense network UDN, and therefore the interferences among the base stations can be reduced, and the system performance can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and base station for determining a serving base station. Background technique [0002] In LTE 12, SmallCell is introduced, that is, a small cell base station, referred to as a small base station for short. SmallCell is a low-power wireless access node that works in licensed and unlicensed spectrum. SmallCell can be used indoors or outdoors, and can cover 10 meters of indoor space or 2 kilometers in the wild; in contrast, the coverage of macro base stations can reach several kilometers. SmallCell combines femtocell, picocell, microcell and distributed wireless technologies. SmallCell is characterized by dense arrangement and overlapping coverage areas. [0003] As one of the business development requirements of 5G, Ultra Dense Networks (UDN for short) is a network architecture formed by SmallCell through high-density deployment without exact planning requirem...
