A method of cell updating system that includes a first wireless communications system that has a core network and a second wireless communications system that includes several short range access points using licensed wireless frequencies and a network controller for communicatively coupling a user equipment to the core network. The UE has one or more active sessions on a first access point. There is no dedicated radio channel between the ULE and the first access point. The method receives a cell update message from the UE. The method sends a cell update request message from the second access point to the network controller. The cell update request message is for sending from the network controller to the first access point to request information for handling the cell update message received by the second access point. The method receives a cell update response message from the network controller.
