An access system of m2m service in cellular wireless communication system

Abstract

The invention discloses an access system for M2M service in a cellular wireless communication system. The access system comprises a deployed cellular mobile communication network, a deployed base station and a deployed M2M service server, and is characterized in that the access system further comprises an MTC device with a dual-mode communication mode and an M2M service convergence access node with an access point function and a cellular network access function; the MTC device can directly communicate with the cellular network base station or the M2M service convergence access node; when the MTC device can not communicate with the M2M service convergence access node or the MTC device must directly communicate with the cellular network base station, the MTC device directly initiates connection with the base station through a cellular network protocol stack and a radio frequency module and sends up data. When the MTC device is configured to communicate with the M2M service convergence access node, the MTC device sends the M2M service to the M2M service convergence access node through the air interface technology between the MTC device and the M2M service convergence access node.

Description

technical field [0001] The present invention relates to a communication field, in particular to an access system of an M2M service in a cellular wireless communication system. Background technique [0002] Various standards of cellular wireless communication networks supporting machine-to-machine communication (Machine-to-Machine, M2M) include access devices, methods and systems in various standards of cellular wireless communication networks such as 3G networks and 4G networks. M2M refers to a communication mode in which machines communicate directly with machines without human participation. It is generally believed that these machines that can communicate directly can be smart meters (smart water meters, smart meters, etc.), smart home appliances (smart TVs, smart air conditioners, smart monitoring equipment, etc.), smart sensors (fire alarm sensors, vibration sensors, hydrological sensors, etc.) Any device that can access the network. M2M technology can connect a large...

Problems solved by technology

In the current application scenario, in order to minimize the impact on H2H users, the control channel resources and public transmission channel resources that can be used by M2M services are strictly limited.

Under such limited conditions, a large number of MTC devices accessing the cellular network at the same time will cause a very tight wireless resource on the air interface, resulting in a decrease in access performance.
