A method for configuring a neighbor list, comprising: obtaining longitude and latitude information of location of an access point, AP, wherein the AP provides service for a user equipment under the coverage of the AP; and searching a second generation mobile communication system, 2G, base station, BS, full list within a set range with a center defined by the obtained longitude and latitude information to obtain information of 2G BSs falling within the range, and generating the 2G neighbor list of the AP based on the obtained information of the 2G BSs, delivering a configuration file carrying with the 2G neighbor list to the AP, optimizing, by the AP, a received 2G neighbor list to obtain an optimized 2G neighbor list by deleting invalid 2G BSs from the received 2G neighbor list, wherein the optimizing the received 2G neighbor list comprises: delivering, by the AP, measurement control information carrying with the 2G neighbor list to a user equipment, UE, under the coverage of the AP; receiving, by the AP, a measurement report obtained through measuring BSs contained in the 2G neighbor list from the UE; and comparing by the AP, the measurement report received from the UE with the 2G neighbor list to obtain the optimized 2G neighbor list by deleting the BSs not recorded in the measurement report from the 2G neighbor list, wherein the 2G neighbor list of the AP is used for handover of the user equipment from the AP to a 2G BS in the 2G neighbor list. obtaining longitude and latitude information of location of an access point, AP, wherein the AP provides service for a user equipment under the coverage of the AP; and searching a second generation mobile communication system, 2G, base station, BS, full list within a set range with a center defined by the obtained longitude and latitude information to obtain information of 2G BSs falling within the range, and generating the 2G neighbor list of the AP based on the obtained information of the 2G BSs, delivering a configuration file carrying with the 2G neighbor list to the AP, optimizing, by the AP, a received 2G neighbor list to obtain an optimized 2G neighbor list by deleting invalid 2G BSs from the received 2G neighbor list, wherein the optimizing the received 2G neighbor list comprises: delivering, by the AP, measurement control information carrying with the 2G neighbor list to a user equipment, UE, under the coverage of the AP; receiving, by the AP, a measurement report obtained through measuring BSs contained in the 2G neighbor list from the UE; and comparing by the AP, the measurement report received from the UE with the 2G neighbor list to obtain the optimized 2G neighbor list by deleting the BSs not recorded in the measurement report from the 2G neighbor list, wherein the 2G neighbor list of the AP is used for handover of the user equipment from the AP to a 2G BS in the 2G neighbor list. delivering, by the AP, measurement control information carrying with the 2G neighbor list to a user equipment, UE, under the coverage of the AP; receiving, by the AP, a measurement report obtained through measuring BSs contained in the 2G neighbor list from the UE; and comparing by the AP, the measurement report received from the UE with the 2G neighbor list to obtain the optimized 2G neighbor list by deleting the BSs not recorded in the measurement report from the 2G neighbor list, wherein the 2G neighbor list of the AP is used for handover of the user equipment from the AP to a 2G BS in the 2G neighbor list.
