Abstract
A method ( ) for preventing message looping in a telecommunications network ( ) includes the steps of receiving a UDT/S query message, determining a next destination for processing the query message and a route for delivering the query message to the next destination ( ). A determination is then made as to whether the route to the next destination is XUDT/S capable ( ). The UDT/S query message is converted to an XUDT/S format by inserting a hop counter ( ) therein if the route is XUDT/S capable (108). The query message is then delivered to the next destination via the route ( ). The hop counter ( ) in the query message is then decremented at the next destination in response to receiving a message of the XUDT/S format ( ). A message loop error is recognized and processed when the hop counter ( ) reaches a predetermined value.
