Abstract:
1. A method of controlling a dual mode mobile terminal, the method comprising: receiving, via a wireless communication unit of the mobile terminal, synchronous time information from a first communication network, said synchronous time information being used for a system time of the mobile terminal and for system time synchronization of the mobile terminal with the first communication network; receiving, via the wireless communication unit, asynchronous time information from a second communication network, said asynchronous time information not being used for system time synchronization of the mobile terminal with the second communication network; calculating, via a controller of the mobile terminal, a difference between the synchronous time information and the asynchronous time information; calculating, via the controller, an average of the calculated difference between the synchronous time information and the asynchronous time information; storing, in a memory of the mobile terminal, the calculated average difference; receiving, via the wireless communication unit, a message from the second communication network; and setting, via the controller, a reception time stamp of when the message is received based on time information contained in the message received from the second communication network and the calculated average difference.
