Claim:
1. A method for acquiring cell location information, comprising: acquiring, by a serving mobile location center, cell antenna location information from a network-side device; implementing, by the serving mobile location center, positioning operation according to the cell antenna location information; wherein, the network-side device is evolved Node B eNodeB, and the cell antenna location information and corresponding serving cell identification are stored in the eNodeB, the step of acquiring, by a serving mobile location center, cell antenna location information from a network-side device, specifically comprising: the serving mobile location center sends a LTE Positioning Protocol A LPPa message to the eNodeB, which carrying serving cell identification; the eNodeB researches the corresponding cell antenna location information according to the serving cell identification, and returns the cell antenna location information to the serving mobile location center by the LPPa response message; the eNodeB sends a S1 Application Protocol S1AP message to Mobility Management Entity MME, which carrying the cell antenna location information under controlling of the eNodeB; after receiving the S1AP message, the MME transforms the S1AP message into Location Service Application Protocol LCSAP message which carrying the cell antenna location information under controlling of the eNodeB, and sends the LCSAP message to connecting ESMLC.
