Problems solved by technology

The problem is weakened if the operator spends considerable time and effort on the drive / walk test to fully exhaust all possibilities, but because many areas are located indoors that are not accessible from the outside, it only partially solve the problem

Embodiment Construction

[0020] The invention as described below is described in the context of overlapping technologies, in which operators operate two or more radio technologies in parallel, for example WCDMA combined with LTE. However, the present invention also envisages a situation where only one technology is used. According to the present invention, the knowledge of whether it is possible to shut down the cells of the network and at the same time continue to support the network UE is used to save energy by shutting down one or many cells.

[0021] Build a quality map that supports neighboring communities

[0022] For each cell, a table of its neighbor cell coverage can be formed. This table in this article will refer to the database or the cell database. For each UE, a cell entry is formed, which stores one or more quality measurements, and the quality measurements contain the quality that the UE would obtain if it were instead connected to each of the neighbor cells.

[0023] Quality can be quanti...

Abstract

In a method and an apparatus for determining when a cell of a cellular radio system can enter a discontinuous transmission mode is provided. By evaluating qualities from both the cell and neighboring cells for a number of positions and calculating a statistically expected quality distribution of the evaluated qualities conditioned on that certain cells are in discontinuous transmission mode it is possible to generate a distribution which can be compared with at least one requirement thresholds. Based on the comparison it is possible to determine if first cell can use discontinuous transmission mode and still fulfill the requirements.

Description

Technical field [0001] The present invention relates to a method and device for controlling the state of a cell in a cellular radio network. Specifically, the present invention relates to a method and apparatus for determining when a cell can enter a low activity transmission mode. Background technique [0002] Energy efficiency in telecommunications systems is becoming more and more important. There are many solutions, and find them in protocols, algorithms, and hardware. Usually the traffic load in the radio network is diversified; resource utilization fluctuates between night (usually low) and day (usually high); in the night time, the idle capacity is running in the radio network and is not utilized. Therefore, one way to save energy is to suspend part of the radio resources during, for example, 22.00 and 04.00. [0003] However, traditional technologies are not specially constructed with the idea of ​​energy efficiency, so the solutions are often coarse-grained. For exampl...
