Abstract
A mobile radio ( ) with a synchronization apparatus ( ) executes a method ( ) for time synchronizing the radio ( ) and a base station ( ). Base station ( ) and radio ( ) have internal timers ( ). A control unit ( ) in the radio ( ) receives a signal ( ) from the base station ( ) and determines the difference F between timers ( ) in the base ( ) and mobile ( ). The control unit ( ) writes instructions I(i) and their execution times T(i) to a memory ( ) within the radio ( ). One of these instructions I(N) reloads the radio timing counter ( ) with a corrected value C=f(F,B) at a predetermined time T(N)=B which avoids conflicts with other operations of the radio ( ).
