Radio network controller selection for IP-connected radio base station
First Claim
1. A method of operating a radio access network comprising:
- preparing, at a femto radio base station, a node address inquiry for obtaining from a database an internet protocol (IP) address of a controller node for connectivity to the femto radio base station, the controller node having an established communication path to a macro base station node that controls a macro cell of the radio access network, the macro cell overlaying the femto radio base station;
using the internet protocol (IP) address to connect the femto radio base station to the controller node as an active controller node for the femto radio base station.

Abstract
Methods and apparatus enable a femto radio base station (28f) to be connected to an appropriate radio network controller node (26) of a radio access network (24) for use as an active radio network controller node for the femto radio base station. The connection is accomplished the femto radio base station (28f) preparing a node address inquiry and for using the node address inquiry for obtaining an internet protocol (IP) address of an appropriate radio network controller node. The femto radio base station (28f) further uses the internet protocol (IP) address of an appropriate radio network controller node for connecting to the appropriate radio network controller node as its active radio network controller node.

16. A femto radio base station comprising:
-
a resident radio receiver for receiving system information broadcast in a radio access network over an air interface from a node which broadcasts the system information; means for using at least part of the system information for obtaining from a database an internet protocol (IP) address of a controller node for the femto radio base station, the controller node having an established communication path to a macro base station node that controls a macro cell of the radio access network, the macro cell overlaying the femto radio base station. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 39)

27. A radio access network comprising:
-
a database; plural controller nodes; at least one femto radio base station comprising; a resident radio receiver for receiving system information broadcast in the radio access network over an air interface from a node which broadcasts the system information; means for using at least part of the system information for constructing a node address inquiry which includes the system information; an Internet Protocol (IP) interface for sending the node address inquiry to the database, for receiving, as a response to the node address inquiry, an internet protocol (IP) address of an appropriate controller node of the plural controller nodes, and for using the address of the appropriate radio network controller node for connecting the femto radio base station to the appropriate controller node as an active control node for the at least one femto radio base station, the appropriate controller node having an established communication path to a macro base station node that controls a macro cell of the radio access network, the macro cell overlaying the femto radio base station. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 40)
