Embodiment Construction

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0040] According to the first embodiment, a process is provided to automatically adjust the power level of the pilot signal of a cell of a mobile phone network to cover the cell with a sufficiently strong pilot signal, so that the mobile station, That is, the so-called second type network equipment appropriately decodes the pilot signal. Therefore, the automatic adjustment of the pilot signal power, the so-called pilot coverage area or the pilot power coverage area is adjusted to satisfy a predetermined target coverage area with a sufficiently strong pilot signal throughout the cell .

[0041] The pilot signal is a signal provided by each base station, which is also called a first type of network equipment, and the signal carries a bit sequence or code known by the mobile station. The bit sequence may depend on the base station and the secto...

Abstract

The invention proposes a method for controlling a network, comprising at least one cell served by a first type network device, wherein the first type network device is adapted to serve second type network devices, wherein the emission of the first type network device includes an individual pilot signal to the second type network devices, and the emission of the second type network devices includes measurement reports including information on the status and the situation of the respective device, the method comprising the steps of detecting information (S1) in the second type network devices, said information indicating the power level of the pilot signals received, collecting (S2) measurement reports (MR) from the second type network devices, said measurement reports (MR) including the pilot power information gained in the detecting step (S1), evaluating (S3) the pilot signal power coverage in that cell on the basis of a pre-given number of measurement reports (MR), automatically adjusting (S4) the pilot signal power coverage in that cell on the basis of the result of the evaluation step. The invention proposes also a device for controlling a network.

Description

Technical field [0001] The present invention relates to a method and equipment for controlling pilot signal power of a mobile telecommunication system. Background technique [0002] In mobile communication technologies such as UMTS (Universal Mobile Telecommunications System) or GSM (Global System for Mobile Telecommunications), base stations serve a limited number of mobile users according to their current locations. As long as the user is in the cell area of ​​the base station, he can get mobile services from the base station. The overall performance and quality of the service depends on propagation conditions, cell type, cell size, load distribution, and various signal transmissions, especially the power level of pilot signals provided by each base station. [0003] The pilot signal transmitted by each base station carries a bit sequence or code known to the mobile station. The bit sequence may depend on the base station and sector. The mobile station uses the power level of t...
