Patent ID: 8615242

Claim:
A method for cell selection of a heterogeneous network, the method comprising: selecting, by a user equipment (UE), a first cell with a highest signal measurement value in a carrier frequency; synchronizing the UE to the first cell; receiving broadcast information of the first cell, wherein, if the first cell is a macro cell, the broadcast information of the first cell carries an extended indicator bit that is used to identify whether a second cell which power is less than a predetermined value exists in coverage of the macro cell; searching for the second cell from the macro cell if the extended indicator bit identifies that the second cell exists in the coverage of the macro cell; and determining, by the UE, the second cell as a serving cell and camping if the second cell satisfies an S rule; sorting, by the UE, received signals in order of signal strength within a preset time; synchronizing, by the UE, with cells in a sequence corresponding to the order of the signal strength; receiving, by the UE, broadcast information of the cells; searching, by the UE, for the second cell according to the broadcast information of the cells; and determining, by the UE, whether the second cell satisfies the S rule according to the broadcast information of the second cell if the second cell is searched.
