1results about How to "Quick backup" patented technology

The embodiment of the present application provides a data transmission method based on master-backup switching, which comprises the following steps: in the case of switching a target backup base station into a target master base station, sending reset request information to a target terminal; in the case of receiving reset completion information from the target terminal, using first communication data, second communication data and an uplink sequence number to perform data transmission on the target terminal for to-be-transmitted data. The method provided by the embodiment of the present application simplifies backup operation, saves resources for backing up the uplink sequence number, realizes fast and efficient backup, thereby further improving the efficiency of master-backup switching, and the data transmission for to-be-transmitted data can be quickly recovered.
