A method for sending control channel information to a user equipment, UE, based on multi-sector cell networking, wherein a cell comprises a plurality of sectors, the method comprising: obtaining, by an access network device, according to an uplink signal sent by the UE, uplink signal strength information corresponding to each sector of the cell, wherein each sector of the cell uses a same cell identity, and the uplink signal strength information is used to indicate a level of corresponding uplink signal strength; selecting, by the access network device, a working sector for the UE from the plurality of sectors of the cell according to the uplink signal strength information corresponding to each sector of the cell; sending, by the access network device, the control channel information to the UE through the working sector, and skipping sending the control channel information to the UE through the plurality of sectors except the working sector; wherein the selecting, by the access network device, a working sector for the UE from the plurality of sectors of the cell according to the uplink signal strength information corresponding to each sector of the cell comprises: selecting, by the access network device, a first sector corresponding to a maximum value of uplink signal strength information as a first working sector for the UE; determining, by the access network device, a second sector as a second working sector for the UE, if a difference between the uplink signal strength information of the first working sector and uplink signal strength information of the second sector is less than a preset threshold; using, by the access network device, the first working sector and the second working sector as the working sector for the UE. obtaining, by an access network device, according to an uplink signal sent by the UE, uplink signal strength information corresponding to each sector of the cell, wherein each sector of the cell uses a same cell identity, and the uplink signal strength information is used to indicate a level of corresponding uplink signal strength; selecting, by the access network device, a working sector for the UE from the plurality of sectors of the cell according to the uplink signal strength information corresponding to each sector of the cell; sending, by the access network device, the control channel information to the UE through the working sector, and skipping sending the control channel information to the UE through the plurality of sectors except the working sector; wherein the selecting, by the access network device, a working sector for the UE from the plurality of sectors of the cell according to the uplink signal strength information corresponding to each sector of the cell comprises: selecting, by the access network device, a first sector corresponding to a maximum value of uplink signal strength information as a first working sector for the UE; determining, by the access network device, a second sector as a second working sector for the UE, if a difference between the uplink signal strength information of the first working sector and uplink signal strength information of the second sector is less than a preset threshold; using, by the access network device, the first working sector and the second working sector as the working sector for the UE. selecting, by the access network device, a first sector corresponding to a maximum value of uplink signal strength information as a first working sector for the UE; determining, by the access network device, a second sector as a second working sector for the UE, if a difference between the uplink signal strength information of the first working sector and uplink signal strength information of the second sector is less than a preset threshold; using, by the access network device, the first working sector and the second working sector as the working sector for the UE.
