Abstract:
A method comprising the steps of:exchanging information between a multi-mode terminal and at least one base station using a first access technology, the multi-mode terminal being capable of exchanging information with the at least one base station using a plurality of access technologies; identifying an information type associated with the exchanged information; determining at least a second access technology, different from the first access technology, capable of exchanging information of the identified information type, the first and the at least second access technologies forming a plurality of compatible access technologies; determining a minimum radiated power level necessary to exchange the information with the at least one base station for each of the compatible access technologies; and selecting one of the compatible access technologies as an optimal access technology, the optimal access technology requiring a lowest amount of battery energy amongst the compatible access technologies to maintain the minimum radiated power level.
