Abstract

The invention discloses a far-end interference characteristic optimization method and device. The far-end interference characteristic optimization method comprises the steps that a base station obtains the load information of an interfered cell when the interfered cell reaches a fallback state conversion threshold; and whether to perform special subframe configuration fallback on the disturbed cell according to the load information is determined. According to the far-end interference characteristic optimization method provided by the invention, special sub-frame configuration backspacing can be selectively carried out according to the load of the cell, and the problem of cell congestion caused by overlarge network load of the cell after the special sub-frame configuration backspacing is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for optimizing a characteristic of far-end interference. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) cell A is located in a traffic-intensive area, and the area where cell A is located is a coastal city or a plain city affected by seasonal fog, so cell A is vulnerable to remote traffic due to its geographical location. terminal interference. [0003] Assuming that there are inter-frequency neighboring cells with the same coverage or part of the same coverage around cell A, the network load of the interfered LTE cell A (or called the disturbed cell) is heavy, and the inter-frequency neighboring cell of cell A (cell B) The network load is average. Then the current method to reduce the influence of the far-end interference of cell A is (such as figure 1 shown): [0004] Step 101, through the atmospheric wa...
