Time synchronization method and time synchronization device for mobile communications system

摘要

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.

1. A time synchronization method for a mobile communication system, the method comprising:
selecting respectively a candidate optimal time source for one or more ports corresponding to at least two types of time protocols from one or more time sources for the one or more ports, wherein with respect to the one or more ports corresponding to the at least two types of time protocols, the at least two types of time protocols are used for time synchronization respectively, and wherein each type of time protocol corresponds to one candidate optimal time source which has not yet used for system time synchronization; and selecting one system optimal time source which is used for system time synchronization from the selected plurality of candidate optimal time sources for ports corresponding to respective types of time protocols.
