Managing non-coordinated radio access networks

The invention relates to methods and devices for managing a plurality of non-coordinated radio access networks.In an aspect, a method of a mobility management node is provided for managing a plurality of non-coordinated radio access networks (RANs) in a wireless communication network.The method comprises receiving, from a base station of a first of the plurality of RANs, information indicating frequencies available in the first RAN for accessing a network served by the mobility management node, acquiring information identifying a base station of a second of the plurality of RANs, said network being operated by an operator different from those operating the first and second RANs; and transmitting, to the base station of the second RAN, the information indicating the frequencies available in the first RAN for accessing said network.
