TRUST BASED SYSTEM AND METHOD FOR PERFORMING A HANDOVER FROM A SOURCE BASE STATION TO A TARGET BASE STATION

摘要

A method performing handover of a mobile terminal from a source base station to a target base station, which can directly communicate with each other via first respective communication interfaces, and communicate via second respective communication interfaces with a core network entity, the core network entity managing subscriptions to services of at least the target base station and authorizing access to the services via handover to only subscribers to the services. The method includes: obtaining a trust level indication for the mobile terminal, representative of how much the mobile terminal can be trusted when declaring having subscribed to the services of the target base station; performing directly the handover via the first communication interfaces, when the obtained trust level indication is above a first threshold; and otherwise requesting authorization from the core network entity for the mobile terminal to access via handover the services of the target base station.

1. A method for performing a handover of a mobile terminal from a source base station to a target base station, the source and target base stations being adapted to directly communicate with each other via first respective communication interfaces, the source and target base stations being adapted to communicate via second respective communication interfaces with a core network entity, the core network entity managing subscriptions to services of at least the target base station and authorizing access to said services via handover to only subscribers to said services,
said method comprising: obtaining a trust level indication for the mobile terminal, said trust level indication being representative of an extent to which the mobile terminal can be trusted when declaring having subscribed to the services of the target base station; performing directly the handover via the first communication interfaces, when the obtained trust level indication is above a first threshold; and otherwise requesting authorization from said core network entity for the mobile terminal to access via handover the services of the target base station.
