That Recommend
18、ation provides detailed requirements for the functionality identified in the overview below. The information model specified in this Recommendation is being released in phases and presently the requirement identified as OR9 in Recommendation 4.1236 is not met by this information model. OR9 would req
19、uire access to charging information while a call was in progress. Support of this capability would result in introducing complexity that is currently not supported. 5.2.1 Introduction The following operational requirements are defined: Configure triggering of IN-based service feature control; Start
20、call gapping; Stop call gapping; Read current gapping criteria; Configure default values (call gapping); Configure SRF/SCF relaying capabilities of the SSF; Configure SRF assisting; Configure default parameters (service filtering); Read service filtering; Configure a set of originating call set-up d
21、ata for SCF initiated call; Read current defined originating call set-up data for SCF initiated call; Configure IN charging; Configure error handling; Start INAP Measurements counters; Stop INAP Measurements counters; Read current INAP Measurement counters.
