29、 data session. The other party in the voice call may reside on a circuit-based network (either circuit PSTN or cdma2000 1x circuit 1cdma2000 is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2. Geographically (and as

31、ed network (HRPD or cdma2000 1x packet connection). Mobility of the HAT in these use cases is also supported as well as extending these capabilities to video telephony service. This document defines the system requirements that enable the HRPD-cdma2000 1x Interoperability feature as defined by the f
32、ollowing use cases. A: Origination/Termination of a Voice Call with a connected HRPD Data 7 Session: - Use Case A-1: A user in an active connection on the HRPD network, for example, downloading a large file, can originate/terminate a VoIP call in the HRPD network without ending the existing data ses
33、sion. B: Origination/Termination of a Voice Call with a Dormant HRPD Connection: 12 - Use Case B-1: A user that establishes an active data connection and then transitions to a dormant data connection on the HRPD network can receive an incoming voice call on a cdma2000 1x network. In addition, the us
34、er can transition back to a connected state to originate or terminate a VoIP call on the HRPD network. - Use Case B-2: When an incoming voice call occurs, the called party is under both cdma2000 1x and HRPD coverage. C: Mobility between HRPD and cdma2000 1x for Voice Calls: 20 - Use Case C-1: An HAT
35、 that is in a voice call (circuit or packet) on a cdma2000 1x network moves to a congested cell where the call may be dropped, but capacity is available in an overlaid HRPD network, the call can be handed off from cdma2000 1x to the HRPD network. Note that the HAT may have a dormant HRPD connection
36、while connecting to a cdma2000 1x network. Alternatively, the HAT reaches the edge of HRPD coverage and if cdma2000 1x coverage exists, the call can be handed off from HRPD to the cdma2000 1x network. The cdma2000 1x network can redirect the HAT to HRPD during origination of a circuit voice call. No
37、te: Redirection by the HRPD network is for future study D: Mobility of Video Telephony (VT) between HRPD and cdma2000 1x: 31 - Use Case D-1: Video telephony mobility scenarios between cdma2000 1x and HRPD networks should be supported. In the event the cdma2000 1x network does not support VT, or if t
38、he HAT is on an HRPD VT call and moves out of the HRPD coverage, the VT call is handed off to a cdma2000 1x voice call (circuit or packet). When the HAT comes back to HRPD coverage with VT support, the full VT call may be re-established. - Use Case D-2: The VT subscriber is on a VT call on the HRPD
39、network. When the HRPD network becomes unavailable to the VT subscriber, the video component of the call is removed, and the call is handed off to the cdma2000 1x network as a cdma2000 1x voice call. E: Use Case 5, Mobility of VoIP calls between HRPD systems: 42 - Use Case E-1: A VoIP call can be ha
40、nded off between HRPD systems. F: Camping on HRPD Receiving incoming cdma2000 1x voice call: 44 - Use Case F-1: The subscriber is engaged in a VT call on the HRPD system. An incoming voice call arrives on the 1x system and the user is 7 S.R0108-0 v.2.0 1 2 3 4 5 6 7 8 9 10 12 13 14 15 16 17 18 19 20

NOTE: This use case does not preclude the delivery of the voice call on HRPD as VoIP. - Use Case F-2: The called party with a dormant HPRD s
42、ession switches to the cdma2000 1x network and answers the 1x voice incoming call. - Use Case F-3: When a 1x voice incoming call occurs, the called party with an HRPD packet session transfers the current HRPD packet session to the dormant state and switches to the cdma2000 1x network for answering t
43、he incoming voice call. G: Receiving a VT call: 11 - Use Case G-1: The subscriber is engaged in a packet data session on the cdma2000 1x system. An incoming VT call prompts the subscriber to terminate the ongoing packet-data session. This is followed by the transition to HRPD to receive the incoming
44、 VT call. - Use Case G-2: The subscriber is engaged in a packet data session on the cdma2000 1x system. An incoming VT call prompts the subscriber to place the ongoing packet-data session in dormant state. This is followed by the transition to HRPD to receive the incoming VT call. - Use Case G-3: Th
45、e calling party attempts a VT call to a user who does not have a VT subscription. The incoming VT call is established as a voice call. - Use Case G-4: The calling party attempts a VT call to a VT subscriber who is out of the HRPD coverage. The incoming VT call is established as a cdma2000 1x voice c
46、all. - Use Case G-5: A VT subscriber is active in a cdma2000 1x voice call. The incoming VT call is delivered as a cdma2000 1x voice call. CS call waiting indication is presented to the subject subscriber. - Use Case G-6: A VT subscriber is active in a cdma2000 1x packet data call. The network and t
47、he terminal device have VPOP capability. The incoming VT call is delivered as a cdma2000 1x voice call. - Use Case G-7: A VT subscriber is active in a VT call. The incoming voice call is delivered as an HRPD VoIP call. 3 HIGH LEVEL SYSTEM REQUIREMENTS 34 Note that not all requirements identified her
