Embodiment Construction

[0056] Like numbered components in the figures represent the same component or perform the same function. Elements described above need not be described in later figures if the function is the same.

[0057] figure 1 based on BCG 2 A schematic diagram of a standard digital cellular network (Beyond Cellular Green Generation Networks, a super-cellular green generation network). The network comprises a signaling network 100 and a data network 102 . Both signaling network 100 and data network 102 include a plurality of base stations. The base stations of a certain cell can be switched into sleep mode. In sleep mode, the base stations of the data network 102 are switched off and only the base stations of the signaling network 100 are running. This may be performed when there is no data connection or communication connection active between the mobile device of the cell and the base station. Therefore, the energy consumption of each base station is reduced.

Abstract

The invention relates to a method of performing measurements in a digital cellular radio communication network (100; 102; 500), wherein the method comprises: - determining a group (508) of said communication network (100; 102; 500) Free resources of cells, wherein the set (508) of cells includes a plurality of mobile devices, and wherein the free resources are available for use between a base station of the set (508) of cells and the plurality of mobile devices -determine a subset of the plurality of mobile devices; -set the subset of the plurality of mobile devices into detection mode; -determine the location of the subset of mobile devices in detection mode; A test signal is exchanged between the mobile device of the mode and the base station of the group (508), wherein the test signal includes a first and a second pilot signal, wherein the first pilot signal and the second pilot signal Orthogonal, and wherein said test signals are exchanged using free resources; - perform a plurality of measurements of signal strength and / or signal power of said test signals; - determine an average of said plurality of measurements; and - store said average of said plurality of measurements to provide a result of the measurement.

Description

technical field [0001] The invention relates to the field of mobile communications, and more particularly to performing measurements in digital cellular radio communications networks. Background technique [0002] Self-Organizing Networks (SON, Self Organized Networks) are networks that can self-configure and self-optimize their operations with respect to parameterized goals, such as throughput, coverage, switching quality, energy consumption, etc. [0003] The optimization algorithms running in the network base their decisions on measurements and context such as user location, channel state information, user density, and user mobility profiles. The extraction of context in the network is based on measurements performed by mobile devices and network infrastructure during network and user operations. This is a challenging task due to, for example, processing effects in the mobile device and network, signaling overhead of the air interface, and energy consumption in the mobil...
