A method, a system and an apparatus for acquiring cell location information are disclosed in the embodiments of the present invention. The method includes the following steps: a serving mobile location center acquires the cell antenna location information from a network-side device; the serving mobile location center implements the positioning operation according to the cell antenna location information. In the present invention, the cell antenna location information comprising the information of the longitude, the latitude and the altitude and the like is pre-stored in the evolved Node B (eNodeB), Mobility Management Entity (MME) or Evolved Serving Mobile Location Center (E-SMLC), then according to network planning, the Operation and Maintenance (O&M) beforehand completes the configuration operation of the antenna location information of all the cell in the serving region, thereby further the various kinds of the current positioning technical schemes are improved.
