Purpose and Scope
This section describes a Teleservice that is designed to support Over-the-Air Activation (OTA). The Over-the-Air Activation Teleservice (OATS) supports data exchange between a mobile station and a Customer Service Center (CSC)/Over-the-Air Activation Function (OTAF). The data is organized in a specific format referred to as OATS messages (see Section 6). OATS is a Teleservice that can be performed either on a DTC or a DCCH.
The OTA feature consists of procedures that allow a cellular service subscriber to activate (i.e., become authorized for) cellular service without the intervention of a third party. Further description of the feature may be found in ANSI/TIA/EIA-664 [1].
