A method of limiting relay call according to the number of idle trunks in a mobile communication exchange

摘要

1. The technical field to which the invention described in the claims belongs;Mobile communication exchange;2. Technical challenges to be solved by the invention;In case of performing the relay call processing function in the conventional mobile communication exchange, if the call restriction according to the idle trunk line is not performed, the system will be busy when a large number of calls are generated, and when registering the restriction rate of the call restriction, This is to solve the problem that can not be registered.;3. The point of the solution of the invention;A first step (ST1-ST3) of judging whether a call in the local exchange (1) or a call to the other exchange (2) is a call processing request; A second step (ST4-ST6) for determining whether the relay call restriction function has been activated by performing a relay call processing if there is a relay call request to the other station switching center (2); And a third step (ST7-ST11) for comparing upper and lower threshold calls by comparing the trunk line threshold value input by the operator with the idle trunk line count value whenever the relay call restriction function is activated.;4. Important Uses of the Invention;Applies to mobile communication exchanges.
