LOW PROBABILITY CONNECTION CALL REGISTRATION METHDO BY THE MESSSAGE OF INCOMPLETE CALL FINISH REASON IN ATM SWITCHING SYSTEM

摘要

1. Technical field to which the invention described in the claims belongs;Low probability connection call registration method.;2. Technical Challenges to be Solved by the Invention;It is intended to provide a method of registering as low probability connection call (RPCC) only for the corresponding incomplete call by distinguishing the cause of incomplete cause by using CAUSE field in the release message in which the reason for call rejection is recorded.;3. The point of the solution of the invention;When a call is rejected, released, or terminated, the reason for the cause (CAUSE) field in the RELEASE message containing the detailed reason is recorded. By setting only the status of the subscriber's calls to low-probability connection calls, it is possible to perform fast and accurate network control and maximize the efficiency of network resources by suppressing ineffective calls.;4. Important Uses of the Invention;Used for call control method.
