Method and system for sending uplink data of machine type communication (MTC) system

Abstract

The invention discloses a method and system for sending uplink data of a machine type communication (MTC) system. In the method, network side equipment and a machine terminal appoint the public radio bearing resources for bearing machine service data in advance; and when the machine terminal is required to send uplink machine service data, a radio resource control (RRC) connection is not required to be established between the machine terminal and the network side equipment, and the machine terminal acquires the right to use the public radio bearing resources in a competition mode, and uses the public radio bearing resources to send the uplink machine service data to the network side equipment. According to the invention, the machine terminal carries out the interaction of signaling information with the network side equipment as less as possible, thus maximizing the use ratio of the radio resources.

Problems solved by technology

However, this method of service data transmission has the following problems for the MTC system: there are many user equipments in the MTC system, and each user equipment needs to establish an RRC connection every time it sends data, but the amount of actually transmitted data is very small and difficult That is, the resource consumption caused by the transmission of signaling messages for the transmission of small data traffic is far greater than the resource consumption of the transmitted data volume itself, so this waste of resources needs to be avoided by adopting better methods

[0010] If the resource consumption is only reduced by reducing the signaling data brought by the establishment of the RRC connection, the solution can be solved by making the user equipment always online without changing the existing technology. However, the always-on method Compared with the idle mode, it will inevitably bring about an increase in power consumption, which is also contrary to the low power consumption characteristics of the machine terminal.
