Estimating the term…
The present invention relates to a method of switching from a first mobile radio mode to a second mobile radio mode in a multimode mobile radio terminal having a first part and a second part respectively operating in compliance with first and second radio access technologies and respectively provided with first and second clocks, the method including the following steps: locking the first part of the mobile terminal to a first mobile radio mode associated with an first clock; the mobile terminal calculating the time shift between the clocks of the two mobile radio modes; correcting the time of a second part of the terminal using the calculated time shift; and switching a second part of the mobile terminal to a second mobile radio mode associated with the second clock.
A method of switching from a first mobile radio mode to a second mobile radio mode in a multimode mobile radio terminal having a first part and a second part respectively operating in compliance with first and second radio access technologies respectively associated with the first and second mobile radio modes and respectively provided with first and second clocks, the method comprising the following steps:
A multimode mobile radio terminal including a microcontroller and having two parts adapted to communicate in compliance with respective radio access technologies associated with respective different mobile radio modes, the terminal including a counter adapted to count the time that has elapsed between the start of a radio frame of the first technology and the start of a radio frame of the second technology, means for calculating the time shift between said radio access technologies, and means for updating the time of a part of the terminal to the time of the technology associated with said part.
