Problems solved by technology

[0006] This approach delivers good quality of service, but has several disadvantages: Large buffers are used to avoid service interruptions
Long wait times before service starts, as well as interruptions in the middle of a video or music sequence, can cause considerable frustration for end users

Embodiment Construction

[0041] In Fig. 1, in step 101, an end user is in a femtocell and requests a video streaming service. Of course, the end user could also be in a hotspot or any other high bit rate area. When video streaming service delivery is started, the end user stays in the femtocell, and the multimedia network controlling the delivery divides the video stream into a basic stream, a first enhancement stream and a second enhancement stream for transmission (step 103). Next, the end user moves near the femtocell border (step 105). The multimedia network responds by inferring the most probable data volume of the basic data stream that is most likely required to provide a good quality of experience until re-entering the femtocell (step 107). To infer this data volume, the multimedia network statistically determines the travel time based on the distance to the surrounding femtocells and an estimate of the end-user velocity, ie, the end-user's speed and direction.

Description

[0001] The present invention is based on the priority application EP 05 292 230.9, which is incorporated herein by reference. technical field [0002] The present invention relates to a method for sending data to a terminal in a discontinuous coverage wireless network comprising at least one high bit rate zone, and the discontinuous coverage wireless network and / or the terminal comprising a cache. The present invention also relates to a module for sending multimedia data to a terminal in a discontinuous coverage wireless network, a terminal for receiving multimedia data in a discontinuous coverage wireless network, and a module for sending multimedia data to a terminal in a discontinuous coverage wireless network Computer Program Products. Background technique [0003] In mobile networks, wireless performance is generally unstable. Certain types of traffic have higher priority than others, eg real-time traffic over streaming or data transmission. When a terminal has poor ...
