ABSTRACT:
A method is disclosed for selecting mode of operation for a mobile station in a mixed telecommunication system comprising first and second core networks, wherein the mobile station is adapted for selective operation in either of first and second modes associated with the first and second core networks, respectively. When the mobile station enters a combined cell, it is furnished with specified information for use in selecting mode of operation, the specified information usefully being combined with information relating to history of the mobile station prior to entering the combined cell. The specified information may be parameters introduced in the cell broadcast system information, parameters which are introduced in the mobile station SIM information, or may be explicit signaling messages specifically directed to the mobile station. Specific information also may be a combination of parameters from each of these sources.
