Introduction to J-STD-038-A:

Network Interworking Between GSM MAP and ANSI-41 MAP

Proposal: Modify J-STD-038-B to Include

Two-Way Packet Data Roaming

DHR 06/26/03 2

Introduction to J-STD-038-A

• Service Descriptions

• Mobile States, Network Requirement

• Network Reference Model

• IIF Interfaces

• Message Flow Illustrations

• Implementation Alternatives

• Proposal: Add CDMA Packet Data Service (C-PDS) in foreign Mode

DHR 06/26/03 3

Service Descriptions

• Authentication

• Call Forwarding (CFU, CFB, CFNRy, CFNBc; CFU, CFB, CFNA, CFD)

• Optimal Routing for Late Call Forwarding

• Call Waiting

• Three-Way Calling & Multi-Party

• Calling Number/Line ID

• Call Barring & Operator Determined Barring

• Short Message Teleservice Support (ANSI-136)

• Message Waiting Notification

• GPRS in GSM Foreign Mode (1-way packet data roaming only)

DHR 06/26/03 4

Network Requirement:Interoperability and Interworking Function (IIF) provides signaling control

between GSM and ANSI-41 Networks

Mobile States:•GSM Native Mode

•ANSI-41 Foreign Mode

•ANSI-41 Native Mode

•GSM Foreign Mode

•GPRS in GSM Foreign Mode

– J-STD-038-A includes TDMA-136/GSM/GPRS MS

– J-STD-038-B assumes cdma2000/GSM/GPRS SIM or UIM

Add to J-STD-038-B: CDMA Packet Data Service for Network Interworking Between GSM MAP and ANSI-41 MAP

Overview:

• C-PDS Service Description in TIA-EIA-IS-880

• Network Impact from TIA-EIA-IS-835

• Message Flow Illustration

• Recommendation to CDG-IRT

DHR 06/26/03 16

IS-880 C-PDS Includes:• Private or Public Packet Data Network (PDN) Access

• Subscription (MS) Options

– Packet Data Service (PDS) only

– Voice Service (VS) or PDS (not simultaneous)

– Simultaneous VS and PDS

• C-PDS Quality of Service

– sensitivity to data rate, delay, error rate

– Assured and Non-Assured Options

• Call Detail Record data elements

• Intersystem Handoff

To be done by CDG-IRT

• Recommend TR45.2 add C-PDS in Foreign Mode to

J-STD-038-B

– Reference IS-880 and IS-835

– Provide stage 1 service description

– Update IIF for subscriber data mapping from GSM HLR to ANSI-41 VLR for 2-way packet data service

• Add RADIUS server function in or for GSM Network

• Update Requirements as Needed for MS, R-UIM and SIM
