Handing over an ongoing communication of a mobile terminal located in a moving conveyance

摘要

The present invention concerns a method and a system for transferring an ongoing communication in which a mobile terminal is involved between a first and a second base stations of a wireless cellular telecommunication network, one of the base stations being located in a moving conveyance. The first base station:
- obtains an information indicating that the first base station will become neighbour of the second base station,
- identifies a mobile terminal which is currently under communication with a remote telecommunication device through the first base station,
- transfers a message to the second base station requesting the second base station to prepare resources enabling the continuation of the communication through the second base station,
- obtains an information indicating that the first base station is neighbour of the second base station,
- transfers the ongoing communication in which the mobile terminal is involved to the second base station.
