A method for registering a low probability connection call using payload type indication (PTI) field information in a cell header in an asynchronous delivery mode switching system

摘要

1. The 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;(RPCC) using the PTI field information which indicates the jam occurrence information of the switching element in the cell header when the ATM cell meets the congestion state after passing through the specific switching element.;3. The point of the solution of the invention;If the cell experiencing the congestion has experienced a congestion with reference to the PTI field of the current serving cell header after setting the threshold value, the number of the experienced cells is increased and if the number is greater than the threshold value within the unit time, the number of congested cells is increased, Also, if it is received above the threshold within the unit time, it registers as a low probability connection call and requests call control for the code.;4. Important Uses of the Invention;Used for call control.
