Problems solved by technology

These solutions are complex, costly, and their efficiency has not been proven in real-world cases
[0009] The second approach to address discontinuities in wireless coverage is based on dense wireless deployments, which are not ideal due to increased network costs
However, if the wireless transmission conditions are poor, in particular, the quality of video data sent in this way will be severely degraded, and in the worst case even only voice data will be sent, so solutions based on scalable codecs cannot Guaranteed seamless service

Embodiment Construction

[0035] FIG. 1 shows a wireless communication network 100 comprising a base station 10 and a mobile terminal 20 between which data can be exchanged via a wireless link 15 .

[0036] FIG. 1 also shows the radio coverage area 50 of the base station 10 . The wireless coverage area 50 is divided into a plurality of areas 51, 52 and 53, wherein each area is characterized by certain data transmission conditions, such as maximum data transmission rate or carrier-to-interference ratio.

[0037] For example, the area 51 adjacent to the base station 10 is characterized by a relatively high data transmission rate due to its proximity to the base station 10 .

[0038] In contrast, region 52 does not support the high data transfer rate given in region 51 . The next area, area 53 , currently contains the mobile terminal 20 and is characterized by the lowest possible data transmission rate in the entire radio coverage area 50 of the base station 10 .

[0039] In order to provide a seamless ...

Abstract

The invention relates to a method of operating a radio communications network (100), wherein data is transmitted from a base station (10) of said network (100) to a terminal (20) via a radio link (15). The inventive method is characterized in that data to be transmitted from said base station (20) to said terminal (20) is transmitted in advance to said terminal depending on current data transmission conditions of said radio link (15) and stored to a cache memory (21) of said terminal (20).

Description

[0001] Cross References to Related Applications [0002] The present invention is based on the prior application EP05292528.6, the content of which is incorporated herein by reference. technical field [0003] The invention relates to a method of operating a wireless communication network, wherein data are transmitted from base stations of said network to terminals via wireless links. [0004] The invention also relates to a terminal capable of receiving data via a wireless link from a base station of a wireless communication network, and a base station. Background technique [0005] Methods and systems of the above-mentioned type are known from the prior art and suffer from some disadvantages, eg discontinuities in the radio coverage supporting the radio link between the base station and the terminal. Such a discontinuity may cause, for example, an interruption of data transmission between the base station and the terminal, and is therefore highly undesirable. [0006] In...
