Method for discovering handover capabilities of a mobile communication network, system for discovering handover capabilities of a mobile communication network, user equipment, programs and computer program products

摘要

The present invention relates to a method for discovering handover capabilities of a mobile communication network, the mobile communication network includes a core network and a radio access network, and user equipment can be connected to the mobile communication network using a first radio access technology. And the user equipment can be connected to the mobile communication network using a second radio access technology, the method is that the user equipment receives handover performance information from the mobile communication network and the user equipment is first for communication with the core network. Or using the second radio access technology, when the user equipment is using the first radio access technology, the user equipment is configured to receive the handover performance information received from the mobile communication network from the first radio access technology. Hand with technology Initiating a handover from the first radio access technology to the second radio access technology, and / or the user equipment uses the second radio access technology only if it indicates the performance of the mobile communication network supporting the dropover. If present, the second radio is only when the user equipment indicates the performance of the mobile communication network supporting handover from the second radio access technology to the first radio access technology, the handover performance information received from the mobile communication network. And initiating a handover from the access technology to the first radio access technology.
