Embodiment Construction

[0026] will now refer to Figure 1 to Figure 2 A first embodiment of a cellular telecommunication network 1 is described. The cellular telecommunication network 1 comprises a first base station 10, a second base station 20, a third base station 30 and a fourth base station 40, wherein the first base station 10 is a macro base station and the second, third and fourth base stations are femtos base station. Therefore, the macro base station has a relatively large coverage area compared to the coverage areas of the second base station, the third base station and the fourth base station. The first base station 10, the third base station 30 and the fourth base station 40 are in fixed geographic locations, while the second base station 20 is attached to a movable train. The route of the second base station is as follows figure 1 shown, and traverses the overlapping portion of the respective coverage areas of the first base station 10, the third base station 30 and the fourth base ...

Abstract

The invention relates to a method, a network node and a computer readable data carrier in a cellular telecommunication network. The cellular telecommunication network includes a first base station and a second base station, the second base station is mobile, and user traffic of the UE is transmitted between the first cellular core network node and the UE via the first base station and the second base station, the method includes: determining the first base station The first identification of three base stations and the second identification of the 4th base station, the overlapping coverage of the corresponding coverage area of ​​the 3rd base station and the 4th base station covers the route of the second base station; Determine the time when the second base station arrives in the overlapping; In the second base station Determine the first configuration parameter of the third base station and the second configuration parameter of the fourth base station before the arrival time; initiate a handover from the second base station to the third base station based on the determined first configuration parameter of the third base station; The second configuration parameter of the base station configures the transmission of the second base station.

Description

technical field [0001] The present invention relates to mobile base stations in cellular telecommunication networks. Background technique [0002] A cellular telecommunications network typically includes multiple base stations, each having a coverage area for communicating with multiple user equipments (UEs). Traditionally, base stations are located in fixed geographic locations by being installed at specific sites or on buildings. These fixed base stations utilize local (usually wired) power and data communication interfaces to receive power and connect to the cellular core network (often referred to as backhaul). [0003] Modern cellular telecommunication networks also provide mobile base stations. These mobile base stations are in a non-fixed geographic location and can change their location either by self-powered movement or by being mounted on a movable vehicle such as a train or car. The mobile base station also has a coverage area for communicating with multiple UE...
