Claim:
An apparatus comprising: at least one processor, and at least one memory storing a computer program; in which the at least one memory with the computer program is configured with the at least one processor to cause a mobility management entity to at least: collect at the mobility management entity: profiles of user equipments operating under different wireless networks associated with different core networks or different operators, all of which operate using a same radio access technology (RAT), each profile comprising at least parameters for multi-operator coordination; and measurement information of an unlicensed band; based on the collected profiles and measurement information, allocate to the different wireless networks radio resources on the unlicensed band; and in response to a reply from one of the different wireless networks rejecting the said allocation, re-allocate resources on the unlicensed band to the one wireless network from which the reply was received but not re-allocate resources on the unlicensed band which were allocated to any of the different wireless networks other than the one wireless network from which the reply was received; wherein the different wireless networks are evolved universal terrestrial radio access networks (EUTRANs), and the radio resources are allocated to the different wireless networks: according to a pre-defined agreement collected by the mobility management which sets forth relative shares of the unlicensed band for the different wireless networks; or as decided by the mobility management entity based on the profiles and the measurement information which the mobility management entity retrieves from a home subscription server and from other mobility management entities of the different wireless networks.
