Abstract
A system and method in a radio telecommunications network for reconnecting a disconnected emergency call between a mobile station having an emergency (emergency MS) and a public safety answering point (PSAP). The method reduces the probability that a second MS such as a cloned MS will respond to a reconnection attempt. If a second MS responds to a first reconnection attempt, procedures are implemented to locate and connect the emergency MS. The network includes a serving mobile switching center (MSC) serving the emergency MS that includes a re-paging mechanism and a reconnection timer. The PSAP includes an alarm generator that notifies the serving MSC when a second MS is connected to the PSAP rather than the emergency MS. Upon receiving an alarm from the PSAP, the serving MSC reattempts to page the emergency MS.
