Problems solved by technology

However, this method of business data transmission will bring the following problems to the MTC system: there are many user equipments, and the RRC connection process must be established every time data is sent, and the actual amount of data transmitted is very small, that is, the transmission of small data The resource consumption caused by the transmission of signaling messages due to traffic flow is far greater than the resource consumption of the transmitted data volume itself, so this kind of resource waste needs to be avoided by adopting better methods

Abstract

The invention discloses a downlink data transmission method and a downlink data transmission system in a machine type communication system, which are suitable for a wireless communication system. The downlink data transmission method comprises the following steps: when a network side necessarily sends the downlink machine service data to a machine terminal, network side equipment issues a signaling for notifying the machine terminal to receive the downlink machine service data and releases the downlink machine service data and the receiving end identifying information of the downlink machine service data on a preset downlink shared wireless carrying resource, wherein the signaling issued by the network side equipment unnecessarily feeds back uplink response. The technical scheme of the invention greatly reduces the cost of the resources for the signaling message interaction, so that the utilization rate of the wireless resources is maximized.
