METHOD AND SYSTEMS FOR ENERGY SAVING BY CONTROL OF THE FIRST RADIO COMMUNICATION UNIT ON THE BASIS OF THE SECOND RADIO COMMUNICATION UNIT

摘要

1. A method of using information from a first radio communication unit in a device for controlling a second radio communication unit in a device, comprising the steps of: obtaining information regarding a first radio network from a first radio communication unit; determining whether to connect a second radio communication unit to a second radio network, on based on the information received regarding the first radio network; turn on or off the power of the second radio communication unit based on the definition. 2. The method of claim 1, wherein obtaining information regarding the first radio network from the first radio communication unit comprises obtaining a mast identifier of a cellular telephone network in communication with the first radio communication unit. The method of claim 2, wherein: determining whether to connect the second radio communication unit to the second radio network, based on the received information regarding the first radio network, comprises comparing the obtained identifier with a list of identifiers stored in the memory to determine if there is a match; turning on or turning off the power of the second radio block based on the definition includes turning on or off the power of the second radio block based on whether the received identifier matches the value stored in the memory. 4. The method of claim 3, further comprising the steps of: establishing a connection to a second radio network; obtaining a mast identifier of a cellular telephone network in communication with the first radio communication unit during an established connection with a second radio network; and write the received identifier into memory. 5. The method of claim 3, further comprising the steps of: trying to establish
