Method for controlling handover in a mobile telecommunications network.

摘要

Handover of a mobile terminal conducting a call in a communications network comprising a plurality of radio access networks is controlled in accordance with a network policy, such as minimising the cost of a call or maximising the use of higher quality resources. A handover manager receives a trigger indicating a requirement for handover between access networks. Possible handovers meeting the requirement are tested against a network policy, and the handover is carried out in accordance with both the communication requirement and the network policy.
