34、Ballot resolved TIA-1092 1 1 Introduction 1 Introduction 1 To provide the roaming MS with Simple IPv41based access across cdma20002packet data 2 systems which are managed by different administrative domains, an inter-working scheme is 3 required. The inter-working scheme allows the home domain to co

35、ntrol the delivery of services to 4 the roaming MS. A home domain control model for Simple IP based access enables the roaming 5 MS with home domain access, with minimum requirements in the foreign domain to which the 6 roaming MS is connected. This specification describes an inter-working scheme ba

36、sed on the 7 tunneling of the Simple IP packet data traffic of the roaming MS, between a foreign domain and a 8 home domain. 9 1.1 Scope 10 The scope of this specification includes tunneling support for the Simple IP packet data subscriber 11 roaming across cdma2000 packet data systems that are admi

37、nistered by different service 12 providers. In this specification, the tunneling scheme is specified in the context of layer-two 13 tunneling. Other tunneling schemes are not precluded. 14 15 1Simple IPv4 will be referred to as Simple IP 2cdma2000is the trademark for the technical nomenclature for c

45、dma2000 packet data systems: 3 a. Support roaming for Simple IP packet data, with layer-two tunneling across cdma2000 4 packet data systems (based on 1). 5 b. Minimize additional requirements for the cdma2000 packet data system for Simple IP 6 packet data roaming. 7 c. Require no changes to the exis

46、ting cdma2000 packet data system level architecture. 8 d. The QoS support, under roaming conditions, for Simple IP packet data across cdma2000 9 packet data systems is limited to best effort. 10 e. The handoff of packet data sessions across cdma2000 packet data systems is not 11 supported for Simple

47、 IP packet data roaming. 12 f. The home domain control of the services provided to the roaming MS, for Simple IP 13 packet data, with tunneling support. 14 g. For layer-two tunneling, a standard protocol such as L2TP is applicable. 15 TIA-1092 4 4 Definitions and Abbreviations 4 Definitions and Abbr

49、his is the cdma2000 packet data system which administratively owns the 7 cdma2000 packet data MS. 8 Interworking Function (IF): This is a cdma2000 packet data aware network function which 9 provides layer-two tunneling support for the connectivity and transport of signaling and/or bearer 10 data exchanged between the Home System and the Foreign System. 11 Non-tunneled Mode (NM): This indicates the absence of the TM capability in a cdma2000 12 packet data system. 13 Roaming Exchange: This is a third-party which provides the IF, the proxy A
