Apparatus and method for M2M communications

Abstract

An apparatus and a method for machine-to-machine (M2M) communication are disclosed. The present invention abstracts a device through a pre-stored device master template and a resource master template, manages the M2M communications through an interface accessible to a resource, and periodically synchronizes information. The present invention can solve a scalability problem of a system and a heterogeneity problem of the interface accessible to the resource, minimize a load of a network service capability layer without inhibiting service quality, and perform synchronization.

Description

technical field [0001] The present invention relates to a device and method for M2M (Machine-to-Machine, machine-to-machine) communication, in particular, to a device master template (device master template) and a resource master template (resource master template) that have been stored ) to abstract devices, perform M2M communication through an interface (interface) that can access resources (resource), and periodically synchronize information with the device and method. Background technique [0002] In order to promote communication services between objects and devices, the European Telecommunications Standards Institute (ETSI), which is an international standardization association, is developing the ETSI M2M standard. The ETSI M2M standard defines concepts such as network application (network application: NA), device application (device application: DA), network service capability layer (network service capability layer: NSCL), service capability layer (service capability...

AI Technical Summary

Problems solved by technology

The first problem concerns the scalability of the system (scalability), that is, multiple devices connected to a network service function layer (NSCL) will lead to performance degradation

The second problem involves the heterogeneity of the interface (interface) that can be used to access resources (resource). Even for the same type of equipment, the access interfaces corresponding to different manufacturers and models may be different.

When multiple network applications (NA) and multiple devices are connected to one network service function layer (NSCL), if synchronization occurs at an excessively high frequency, it will cause a load on the system built with the network service function layer (NSCL) increase, resulting in an increase in system construction costs

In contrast, if synchronization occurs too infrequently, although the system load is small, it may not be able to meet requirements such as the message delivery speed expected by the network application (NA)
