Abstract
The present invention discloses a radio connection re-establishment method, including: starting a first timer if a first preset number of out-of-synchronization indications are obtained continuously, where the first preset number and/or a duration of the first timer corresponds to a cell of highest signal quality measured by a user equipment UE; and triggering a radio resource control RRC re-establishment procedure if a second preset number of synchronization indications are not received before timeout of the first timer. The radio connection re-establishment method in the present invention reduces overhead.
Claims10
A radio connection re-establishment method, comprising:
- measuring neighboring cells, and obtaining a cell of highest signal quality;
- receiving an out-of-synchronization indication;
- starting a first timer if a first preset number of the out-of-synchronization indications are obtained continuously, wherein the first preset number is a preset number corresponding to the cell of the highest signal quality, and/or a duration of the first timer is a duration corresponding to the cell of the highest signal quality;
- and
- triggering a radio resource control (RRC) re-establishment procedure if a second preset number of synchronization indications are not received before timeout of the first timer.
A user equipment, comprising:
- a first processing unit, configured to start a first timer if a first preset number of out-of-synchronization indications are obtained continuously, wherein the first preset number and/or a duration of the first timer corresponds to a cell of highest signal quality measured by the user equipment (UE);
- and
- a second processing unit, configured to trigger a radio resource control (RRC) re-establishment procedure if a second preset number of synchronization indications are not received before timeout of the first timer.
A base station, comprising:
- an obtaining unit, configured to obtain multiple first preset numbers, wherein the multiple first preset numbers correspond to different cell coverage ranges, or correspond to different transmit power strengths, or correspond to PCIs of different cells, or correspond to types of different cells, or correspond to first ranges of different cells, wherein different types of cells have different coverage ranges or different transmit power, and the first range is a range in which signal strength of this cell is greater than signal strength of a macro cell;
- and
- a sending unit, configured to send the multiple first preset numbers to a user equipment.
