41、 (AS-ILCM): models AS behavior for handling SIP 22 information for an incoming leg. 23 24 Application Server information (AS-info): AS-info contains individualized information concerning one 25 particular Application Server entry. 26 This information contains e.g. Application Server Address (6.9.2.1

42、) and its corresponding Default IP 27 Multimedia Handling information (6.9.2.2). 28 29 Application Server Outgoing Leg Control Model (AS-OLCM): models AS behaviour for handling SIP 30 information for an outgoing leg. 31 32 Combined ILSM OLSM Incoming/outgoing Leg State Model: models the behaviour of

43、 an S-CSCF 33 for handling SIP messages on an incoming and outgoing session leg. 34 35 Filter Criteria (FC): the information which the S-CSCF receives from the HSS or the AS that defines the 36 relevant SPTs for a particular application. 37 They define the subset of SIP requests received by the S-CS

44、CF that should be sent or proxied to a particular 38 application. 39 40 Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA-873-003 3 Incoming Leg Control Model (ILCM): models t

45、he behaviour of an S-CSCF for handling SIP information 1 sent to and received from an AS for an incoming session leg. 2 3 Initial Filter Criteria (iFC): filter criteria that are stored in the HSS as part of the user profile and are 4 downloaded to the S-CSCF upon user registration. 5 They represent

46、a provisioned subscription of a user to an application. 6 7 Initial Request: a SIP request that either initiates the creation of a new dialog or is part of a standalone 8 transaction. 9 10 IP Multimedia session: IP Multimedia session and IP Multimedia call are treated as equivalent in the 11 present

47、 document. 12 13 IP Transport Subsystem: refers to any collection of network entities that provides the underlying IP 14 transport for use to provide connectivity to or between IMS entities. 15 16 Outgoing Leg Control Model (OLCM): models the behavior of an S-CSCF for handling SIP information 17 rec

48、eived from and sent to an AS for an outgoing session leg. 18 19 Private User Identity: a unique global identity defined by the Home Network Operator, as defined in 3. 20 21 Public User Identity: the public user identity/identities are used by any user for requesting 22 communications to other users

49、and are in the form of a SIP URI or TEL URL as defined in 3. 23 24 Service Point Trigger (SPT): a point in the SIP signaling that may cause the S-CSCF to send/proxy the 25 SIP message to an SIP AS or an OSA SCS. 26 The subset of all possible SPTs which are relevant to a particular application are defined by means of Filter 27 Cr
