ENERGY REDUCTION IN COOPERATING RADIO ACCESS SYSTEMS

摘要

The invention relates to cooperation between first and second wireless access networks that can be used to obtain energy reduction for or traffic routing within the overall telecommunications infrastructure while still enabling accept- able network coverage and satisfactory performance by the telecommunications infrastructure as a whole. The cooperation refers to the fact that the wireless access networks provide duplicate coverage in a particular area when both wireless access networks are active, and that traffic can be switched between the cooperating networks in order to temporarily adjust (e.g. switch off) resources of one or the wireless access networks. In this manner, energy reduction and/or traffic routing can be obtained under the constraint that sufficient service coverage and capacity remains at an acceptable quality.
