The present invention discloses a method and system for improving performance of a positioning system during a continuous positioning process, the method is applied in a mobile communication positioning system, and mainly comprises the following steps: during the continuous positioning process, a mobile positioning center sends a mobile station state inquiring request to a home location register, the home location register receives the inquiring request and returns a mobile station current state response message, the mobile positioning center performs positioning process or terminates positioning process to the mobile station based on the current state of the mobile station. On the one hand, the present method can avoid the circumstances in practical applications that the continuous positioning has terminated while the positioning center and the positioning entity fails to release resources in time, which therefore improves the resource utilization ratio of the positioning center and the positioning entity and improves the performance of the whole positioning system, and on the other hand, it can satisfy demands of continuous tracking a subscriber in special industrial application, which avoids the circumstance of inability to continue previous continuous positioning after restart of a subscriber terminal.
