Abstract
A Network node provides information to a base station indicating a list of forbidden frequencies from which the base station may or may not offer services. The base station checks the received list of forbidden frequencies when considering whether to provide service to user equipments from a new tracking area or a certain access technology. The base station may also transmit a list of allowed frequencies or the list of forbidden frequencies to user equipments to be used thereof. By introducing the possibility to set an amount of frequencies as forbidden in the area and access restriction information of user equipments, operators would be able to offer services like home base station in a simple way to customers.
