Abstract

The invention provides an inter-cell interference coordinating method and device. The method comprises the steps of determining a high-interference physical resource block and a high-interference service corresponding to the high-interference physical resource block, wherein the high-interference service is borne by the high-interference physical resource block currently; detecting whether the grade of quality of service (QoS) of the high-interference service reaches a preset standard QoS grade corresponding to the high-interference service and not sending an interference overloading alarm to a base station nearby if so. According to the inter-cell interference coordinating method and device, after the high-interference physical resource block is determined, the interference overloading alarm is not sent to the base station nearby if the QoS grade of the high-interference service borne by the high-interference physical resource block reaches the preset standard QoS grade corresponding to the high-interference service, and therefore the number of times of signaling interaction caused by inter-cell interference coordination is effectively reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for inter-cell interference coordination. Background technique [0002] With the development of Long Term Evolution (LTE for short), in order to solve the problem of severe interference to cell edge users in the current LTE technology, Inter-Cell Interference Coordination (ICIC for short) has gradually become an important part of LTE technology. research focus. [0003] The existing ICIC scheme is that, according to the obtained current value of the interference parameter of the physical resource block corresponding to the edge user, if the ICIC device detects that the current value of any of the interference parameters is greater than the preset threshold corresponding to the interference parameter , then determine the physical resource block as a high-interference physical resource block, and send an interference overload alarm including the identity of th...
