Patent ID: 8412230

Claim:
A method to configure relations between Evolved Universal Terrestrial Radio Access Network (E-UTRAN) cells and Generic Access Network (GAN) cells in a generic access node controller (GANC) in a Circuit Switched Services over Long Term Evolution via Generic Access Network (CSoLTEvGAN) architecture, said method comprising: receiving, in a signaling message, cell identification information for an E-UTRAN cell from a mobile terminal; determining cell identification information for a GAN cell by translating at least one portion of the cell identification information for the E-UTRAN cell to at least one portion of the cell identification information for the GAN cell; creating an entry within a translation table the to map cell identification information for the E-UTRAN cell to the determined cell identification information for the GAN cell, or to map the determined cell identification information for the GAN cell to the cell identification for the E-UTRAN cell; copying the values of a Mobile Country Code (MCC) and a Mobile Network Code (MNC) in the cell identification information for the E-UTRAN cell to the values of an MCC and MNC in the cell identification information for the GAN cell; copying the 12 most significant bits of an E-UTRAN Cell Identifier (ECI) are copied to the 12 least significant bits of a Location Area Code (LAC) in the cell identification information for the GAN cell; and copying the 16 least significant bits of the ECI to a Cell Identity/Service Area Code (CI/SAC) in the cell identification information for the GAN cell.
