1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0700714.2000(R2015) Stage 2 Service Description for Personal Communications Service Enhanced Priority Access and Channel Assignment (PACA-E) Supplementary Service As a leading technology and solutions development organization, ATIS brings toget

2、her the top global ICT companies to advance the industrys most-pressing business priorities. Through ATIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, bill

3、ing support, operations, and more. These priorities follow a fast-track development lifecycle from design and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American Nat

4、ional Standards Institute (ANSI). ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of oneM2M, a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications sectors, and a memb

5、er of the Inter-American Telecommunication Commission (CITEL). For more information, visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards d

Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that a

36、1 Radio Terminal Function (RTF) (FE1) The RTF is the point from which the PACA-E subscriber accesses the network. The RTF uses the “a” reference point towards the RCF (see T1.704). 4.2 Radio Control Function (RCF) (FE2) The radio control function interacts with other network functional entities (FEs

37、) to provide the net-work capabilities to interact with an RTF in the processing of a PACA-E call. The RCF uses the “a” reference point towards the RTF, the “crpc” reference point towards the RACF and the “crpc” reference point towards the CCF/SSF (see T1.704). 4.3 Radio Access Control Function (RAC

38、F) (FE3) The radio access control function responds and provides information to service logic in the proc-essing of PACA-E service requests. The RACF uses the “crpc” reference point towards the RCF, the “crasc” reference point towards the CCF/SSF and the “d” reference point towards the SCF (see T1.7

39、04). 4.4 Call Control Function (CCF)/Service Switching Function (SSF) (FE4) The CCF/SSF provides call/connection processing and control. The CCF/SSF manages the PACA-E queue. The CCF/SSF uses the “crpc” reference point towards the RCF, the “d” reference point towards the SCF, the “crasc” reference p

40、oint towards the RACF and the “n” reference point towards the CCF (see T1.704). 4.5 Service Control Function (SCF) (FE5)/Service Data Function (SDF) (FE6) The SCF commands call control functions and mobility management functions in the processing of PACA-E service requests. The SDF stores all data r

41、elated to providing the PACA-E service. The SCF/SDF interacts with other FEs to obtain information required to process the PACA-E call. The SCF uses the “d” reference point towards the CCF/SSF and the RACF, and the “dd” refer-ence point towards the SDF (see T1.704). 4.6 Call Control Function (CCF) /

42、Service Switching Function (SSF) (FE4) Incoming calls to PACA-E subscribers may need to be queued, if the PACA-E subscribers radio facilities (i.e. no radio channels are available) have become congested. These calls arrive from remote CCF/SSFs either from wireless or non-wireless users. The CCF uses

43、 the “n” reference point towards the CCF/SSF (see T1.704). T1.714-20004Figure 2 - PACA-E Procedure (see T1.706)ProcedureDecisionTaskStateOutputInputCommentEndT1.714-200055.1 Priority Call Activation (Access/Egress) This scenario describes the successful activation of PACA-E (access and egress) by an

44、 author-ized RTF, which has PACA-E status demand activated. Figure 3 - Priority Call Activation (Access/Egress) Scenario a) The RACF initiates a Qualification Request (see T1.704). For demand activation, the sub-scriber enters a feature code and sends the request (i.e., presses the SEND button), to

45、activate the PACA-E subscription service. NOTE - For permanent activation, the service is activated during user registration; PACA-E subscrip-tion is included in the users profile, so all call attempts have the PACA-E feature activated. Activation of PACA-E Access and Egress may be performed togethe

46、r or separately. b) The Serving RACF sends a PACA-E Notification (Success) Information Flow to the Visited RCF indicating that the PACA-E Activation was successful. NOTE - If the Activation request is unsuccessful (i.e., caller is not a PACA-E subscriber) the same message flows (steps b) e) occur, e

47、xcept the indication is set to “unsuccessful.” c) The RCF receives the PACA-E Notification (Success) Information Flow from the Serving RACF. The RCF forwards the PACA-E Notification (Success) Information Flow to the RTF, in-dicating that the PACA-E Qualification Request was successful. d) The RTF se

48、nds a PACA-E Notification Acknowledgement (Success) Information Flow to the RCF. e) The RCF receives the PACA-E Notification Acknowledgement (Success) Information Flow from the RTF. The RCF sends a PACA-E Notification Acknowledgement (Success) Informa-tion Flow to the RACF. FE1 (RTF) FE2 (RCF) FE5/6
