Problems solved by technology

The second problem is that small cells open after receiving open requests from multiple neighboring cells
Such a ping-pong effect makes the current opening mechanism also problematic

Embodiment Construction

[0024] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the present invention.

[0025] figure 1It is a schematic diagram of a wireless network 100 with small cells in a plurality of macro cells according to an embodiment of the present invention. The signal-based small cell energy saving scheme uses the X2 interface between the small cell and its serving macro cell. The X2 interface also enables multiple neighboring small cells to communicate with each other. In one embodiment of the present invention, the small cell-to-small cell X2 interface and the small cell-to-macro cell X2 interface are used to send energy saving messages. The wireless network 100 includes three macro cells served by three macro cell base stations 101 , 102 and 103 . The macro cell base stations are connected to each other through the X2 interface. Multiple small cells are located in each macro cell. The five small cells ser...

Abstract

The present invention provides an apparatus and method for energy saving of small cells. In one novel aspect, a small cell that detects a low load condition broadcasts a shutdown request. After receiving the shutdown request message, the small cell enters a freeze state, in which the small cell is prevented from being switched off. In another novel aspect, a small cell in a low load condition requests measurement reports from multiple UEs. Multiple UEs reply with a measurement report request message, which contains the detected neighbor ID and the traffic load of the UE. The low-load small cell contains information obtained from the measurement report in the shutdown request message. In another novel aspect, the small cell broadcasts an open request message. After receiving the open confirmation message from the closed neighboring small cells, the small cell selects one or more target cells to send a cell activation request. Close the small cell, and use the cost function to decide whether to open it after receiving a request to open it.

Description

[0001] Cross References to Related Applications [0002] This application was submitted on July 3, 2013 in accordance with 35 U.S.C.§119 requirements, and the application number is 61 / 842,468 titled "Energy Saving Functionality for Small Cells in E-UTRA and E-UTRAN (Energy Saving Functionality for Small Cells in E-UTRA) -UTRA and E-UTRAN")" application, the subject matter of which is hereby incorporated by reference. technical field [0003] The present invention relates generally to small cell management in wireless networks, and more particularly to energy saving functionality for E-UTRA and E-UTRAN. Background technique [0004] The explosive growth of mobile data requires rapid growth in mobile service coverage and network capacity. A promising solution is to offload data traffic to small cells, such as micro cells, pico cells and femto cells. Small cells may be deployed in hopspot areas of cellular macro cells. Small cells provide low power, low cost and efficient c...
