Method for controlling access to a mobile communications network
Abstract:
A method for redirecting communication requests made by user equipment (6,8) to an access point (2) in a cellular communication system is disclosed. The access point (2) has a shorter communication range than a macrocell in the system. The method comprises the steps of; sending a communication request from user equipment to the access point (2); determining whether the access point (2) has reached a maximum capacity; sending a communication rejection signal to the user equipment (6,8) if the access point (2) has reached maximum capacity; and redirecting the communication request into the macrocell in which the access point (2) is positioned wherein the macrocell and femtocell operate at the same frequency.
