Claim:
1. A positioning method in a multi-carrier system, comprising: aggregating a plurality of cells belonging to a base station for a user equipment; sending a positioning measurement request to the base station of a cell where the user equipment to be positioned resides upon reception of a positioning request; receiving measurement results returned from the base station after performing positioning measurements for the user equipment on a primary carrier and at least one secondary carrier, in response to the positioning measurement request, wherein the primary carrier and at least the one secondary carrier are configured to at least two cells of the plurality of aggregated cells for that user equipment; and positioning the user equipment according to the measurement results; wherein the measurement results returned from the base station after performing the positioning measurements for the user equipment in the at least two cells specifically comprise: all measurement results obtained by the base station through performing the positioning measurements for the user equipment in the at least two cells; or processing results obtained by the base station through performing preset process on measurement results obtained by performing the positioning measurements for the user equipment in the at least two cells; wherein all the measurement results obtained by the base station through performing the positioning measurements for the user equipment in the at least two cells specifically comprise: Timing Advance, TA, values and Angle of Arrival, AoA, values obtained by the base station through the measurements for the user equipment in the at least two cells; wherein when the measurement results returned from the base station after performing the positioning measurements for the user equipment in the at least two cells include all the measurement results obtained by the base station through performing the positioning measurements for the user equipment in the at least two cells, positioning the user equipment according to the measurement results specifically comprises: performing the preset process on the received measurement results to obtain processing results; and calculating a location of the user equipment according to the processing results; wherein performing the preset process on the received measurement results to obtain the processing results specifically comprises one of the following: selecting a set of TA value and AoA value with a least TA value among respective received sets of TA values and AoA values as the processing results; selecting a least one of respective TA values as a TA value in the processing results and selecting an average value of respective AoA values as an AoA value in the processing results; and selecting an average value of respective TA values as a TA value in the processing results and selecting an average value of respective AoA values as an AoA value in the processing results.
