Description

Introduction

R-DATA and SMDPP (Short Message Delivery – Point-to-Point) are
the messages that are used for information transfer through the
TIA/EIA-136 air interface and the TIA/EIA-41 network interface. The
purpose of this chapter is to demonstrate the transport of R-DATA
messages through the TIA/EIA-41 SMDPP and vice versa. Figure 1
illustrates the network model for information transfer between the
air and network interfaces.

The mechanism for information transfer between a source and a
destination through the BMI is called a teleservice. The source
maybe a mobile station or a Teleservice Server (TS). A teleservice
is delivered across the TIA/EIA-136 air interface on a DCCH or DTC
inside a layer 3 R-DATA message, and across the TIA/EIA-41 network
interface inside a layer 3 Short Message Delivery Point-to-Point
(SMDPP) Invoke message. The delivery of the layer 3 message may be
acknowledged by the destination in a TIA/EIA-136 R-DATA ACCEPT or
R-DATA REJECT message and a TIA/EIA-41 SMDPP Return (smdpp) Result
message. The BMI provides the interworking between the Teleservice
Server and the mobile station by translating between the
TIA/EIA-136 and TIA/EIA-41 protocols.

A teleservice may be delivered in point-to-point mode or
broadcast mode. It may be text based, such as Cellular Messaging
Teleservice (CMT), or it may be coded information destined for the
mobile station's storage and use, such as Over-the-Air Activation
Teleservice (OATS) and Over-the-Air Programming Teleservice (OPTS).
The teleservice protocol stack is as shown in Figure 2.
