Scope

This document specifies the technical requirements and test methods for interoperability between Internet of Things (IoT) cellular communication modules and telecom smart cards, aiming to ensure the collaborative operation between cellular communication modules and telecom smart cards, achieve stable communication, and guarantee the cellular network connectivity and service quality of IoT devices. Since the adaptability of cellular communication modules to telecom smart cards affects the achievement of interoperability goals, this document also includes compatibility requirements for cellular communication modules and telecom smart cards to ensure that cellular communication modules and telecom smart cards have the necessary protocol support, command parsing, and functional adaptation capabilities, thereby achieving stable network connectivity and service interoperability. This document includes interoperability and compatibility requirements and test methods in terms of electrical characteristics and communication parameters, initialization, network services, and basic information inquiry. This document is applicable to the research, development, design, and testing activities of IoT cellular communication modules (referred to as "cellular communication modules") and telecom smart card products.
