Introduction

A teleservice is a mechanism for information delivery from a source to a destination through a BMI. The source may be a mobile station or a Teleservice Server (TS). 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 information delivered from the source to the destination is known as user data.

A teleservice message is delivered across the TIA/EIA-136 air interface on a DCCH or DTC inside a layer 3 R-DATA message or, on a PDCH inside a tunneled layer 3 R-DATA message (see TIA/EIA-136-376) 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 Result message. Teleservice Segmentation and Reassembly (TSAR) may be applied to the user data to allow for end-to-end delivery of messages and information which cannot fit inside a single R-DATA or SMDPP Invoke message. Figure 1 shows the Teleservice Protocol Stack for operation with TIA/EIA-136 between TIA/EIA-41.

A teleservice message may also be delivered across the TIA/EIA-136 air interface on a PDCH inside an SM-RL RP-DATA message (see TIA/EIA-136-670), across the GSM network inside an FSM 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 teleservice message may be acknowledged by the destination in a SM-TP message. Teleservice Segmentation and Reassembly (TSAR) may be applied to the user data to allow for end-to-end delivery of messages and information which cannot fit inside a single SM-TP or SMDPP Invoke message. Figure 2 shows the Teleservice Protocol Stack for operation among TIA/EIA-136 200kHz channels, SGSN network, and TIA/EIA-41 network.

A teleservice is uniquely identified across the TIA/EIA-136 air interface by a Higher Layer Protocol Identifier (HLPI), and across the TIA/EIA-41 network interface by a SMS_Teleservice Identifier. There is a one-to-one mapping between the TIA/EIA-136 HLPI and the TIA/EIA-41 SMS-Teleservice Identifier. The BMI provides the interworking between the Teleservice Server and the mobile station by translating 34 between the TIA/EIA-136 and TIA/EIA-41 protocols. The BMI is not required to process the user data portion of a teleservice beyond providing protocol translation.
