<p>The present invention provides a method for processing a call to ensure that the call is selected to be deassigned or released when a value-added service can not be provided according to current application resources state. The method includes: receiving, by an AS, a value-added service call triggered by a switching device (3), determining whether the call can be deassigned according to a preconfigured service policy when the AS finds the value-added service can not be provided according to a current resource state (4); sending a notification for deassigning the call to the switching device when a determining result is that the call can be deassigned (4.1); and processing, by the switching device, the value-added service call as a call not triggering the value-added service (5,6,7). The present invention further provides a system, an AS and a switching device for processing a call.</p> |
