Problems solved by technology

[0005] At present, most of the existing cell interruption detection methods are centralized detection technologies, which require a large signaling overhead and will bring a large burden to the system; in the heterogeneous network to be deployed in the future, a macro base station (Macro Cell ) may have dozens or even hundreds of small base stations (Small Cells), and each Small Cell may be interrupted. Timely positioning and repairing the interrupted Small Cells will help improve user experience. Applying the traditional cell outage detection method in such a large number of densely deployed Small Cells will generate huge computational complexity and high signaling overhead

Abstract

The invention relates to a cell interrupt detecting method based on a neighbor cell reference signal receiving power list and belongs to the technical field of wireless communication. The method comprises the steps that an RSRP list, which can be used for balancing detecting performance and detecting delaying time, of a neighbor cell is established, and distributed type triggering and concentrated judging are used. According to the designed neighbor cell RSRP list, a concentrated large-amount-information collecting process is avoided, signaling overhead in a detecting process can be greatly reduced, and meanwhile detecting performance and detecting delaying time can be well balanced under the situation that user density is very low and channel transmission conditions are very bad. Meanwhile, the cell interrupt detecting method can be used as reference of intensively-deployed Small Cell interrupt detecting in a heterogeneous network.

Description

technical field [0001] The invention relates to a cell interruption detection method based on a neighbor cell reference signal receiving power list, and belongs to the technical field of wireless communication. Background technique [0002] The next-generation broadband cellular mobile communication system (IMT-Advanced) is very different from the traditional cellular network in wireless transmission technology, network architecture, business environment and service mode. Advanced technologies such as MIMO), wireless relay, inter-cell interference coordination, and carrier aggregation provide a transmission rate of up to 1Gbps for multimedia packet services, and can guarantee the performance of cell edge users; (2) Adopt a flat network structure, changing the traditional The centralized control mode of the enhanced base station adopts the negotiation method to carry out the corresponding wireless resource allocation and handover, which reduces the transmission delay and inte...
