Embodiment Construction

[0034] In the M2M system, if the existing scheduling mechanism of the LTE system is adopted, each M2M terminal is independently scheduled, and although a small amount of data is transmitted each time, it still occupies physical downlink control channel (PDCCH) resources. In this case, a large number of M2M terminals will exhaust the PDCCH resources of the system, thereby affecting normal H2H services. This application provides a method for managing M2M terminal groups. M2M terminals are grouped according to the characteristics of M2M terminals, and unified scheduling is performed in units of M2M groups. All M2M terminals in each group only perform PDCCH scheduling once to save PDCCH resources. .

[0035] In order to make the technical principles, features and technical effects of the technical solution of the present application clearer, the technical solution of the present application will be described in detail below in conjunction with specific embodiments.

Abstract

The invention discloses an M2M (machine to machine) communication terminal group management method. The method includes: A, M2M terminals report their supported features or device types to a base station, and the base station distributes the supported common features or the M2M terminals to a same M2M group; B, the base station informs an M2M group identifier and a device identifier of each M2M terminal through RRC (radio resource control) signaling; C, with the M2M group as a unit, the base station dispatches the M2M terminals by means of two-level dispatching; in the first-level dispatching which is physical layer dispatching, wireless resources that carry M2M group dispatching information usage are indicated by a PDCCH (physical downlink control channel); in the second-level dispatching which is MAC (media access control) dispatching, wireless sources that each M2M terminal uses are indicated. The method has the advantages that system PDCCH resources can be saved effectively and the system can contain mass M2M terminals.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a machine-to-machine communication (Machine-to-Machine, M2M) terminal group management method. Background technique [0002] The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which enables all ordinary physical objects that can be independently addressed to realize interconnection and intercommunication. As the most common application of the Internet of Things at this stage, machine-to-machine communication (Machine-to-Machine, M2M) has received extensive attention from various industries, and it is also the focus of research and standard-setting by major standardization organizations. The European Telecommunications Standards Institute (ETSI, European Telecommunications Standards Institute) started with research on typical IoT business use cases, such as smart healthcare, e-commerce,...
