Location information may be provided for a mobile station based on the serving area that is currently serving the mobile station. The location information may include a representative location (e.g., a centroid location of the serving area) and an uncertainty (e.g., a distance between the representative location and a boundary of the serving area). The representative location and uncertainty for a serving area may depend on the status of at least one neighboring area. For example, the effective size of a serving area may become larger when a neighboring area is heavily loaded or out of service. In an embodiment, a location server receives a request to locate a mobile station, selects a representative location and uncertainty for the serving area that is serving the mobile station based on the status of at least one neighboring area, and reports the representative location and uncertainty in response to the request.
