Method and system for data transmission in communication system

摘要

A method for data transmission in a communication system is disclosed in the present invention. The method includes: after the radio access network and the core network finish the initialization, the core network initiates a public bearer establishment or the radio access network requests to establish the public bearer, and the radio access network and the core network establish the public bearer there between; and the radio access network and the core network transmit uplink data and/or downlink data of multiple machine type communication (MTC) equipment by using the public bearer. A system for data transmission in a communication system is also disclosed in the present invention.

1. A method for data transmission in a communication system, comprising:
after a radio access network and a core network have finished initialization, the core network initiating a public bearer establishment or the radio access network requesting to establish the public bearer, and the radio access network and the core network establishing the public bearer there between; and the radio access network and the core network transmitting uplink data and/or downlink data of a plurality of machine type communication (MTC) equipment by using the public bearer; wherein the step of transmitting uplink data of a plurality of MTC equipment by utilizing the public bearer comprises: when the MTC equipment requests to perform an uplink data transmission, the radio access network judging whether the uplink data required to be transmitted by the MTC equipment meet a predetermined condition; for the data meeting the predetermined condition, an already established public bearer is used to perform the data transmission; for the data not meeting the predetermined condition, a dedicated data bearer is established to perform the uplink data transmission for the MTC equipment.
