Abstract
The present invention discloses a time synchronization method and a time synchronization device for a mobile communication system. When the time status of one type of time protocol is bad, a different type of time protocol having a better status can be automatically selected, thereby the system flexibility and the time information quality and reliability can be effectively enhanced. The time synchronization method for a mobile communication system may comprise: selecting respectively an optimal time source for each type of time protocol port of at least two types of time protocol ports; selecting a system optimal time source from optimal time sources for respective types of time protocol ports.
