Offloading data communications between radio access networks

摘要

Embodiments comprise measures, including methods, apparatus and computer program products, for use in access network selection in a telecommunications system. The telecommunications system (20) comprises, at least, a mobile telephony radio access network (23). At one or more network nodes of the mobile telephony radio access network a preference, to offload (15) at least some data communication in the mobile telephony radio access network to a further radio access network other than the mobile telephony radio access network, is identified. In response to this identification, an indication (16,17) of the identified offloading preference is caused to be transmitted, via the mobile telephony radio access network, to at least one user equipment.
