Abstract
A method and apparatus in a communications system for tracking mobile stations. The length and identify of the path of the mobile station is tracked at the mobile station. The path is monitored for a presence of a loop. In response in identifying the presence of a loop, the loop is removed from the path, wherein the length of the path is reduced. Additionally, the length of the path is compared to a threshold and a location update is performed in response to the length of the path being greater than the threshold. The threshold may also be updated at a MSC and then sent to the mobile station.
