Public bearer establishment method, data transmission method and core network side equipment

Abstract

The invention discloses a public bearer establishment method which comprises the following steps of: establishing a group public bearer resource for a machine-to-machine (M2M) communication terminal in a machine type communication (MTC) group by core network side equipment; and allocating the group public bearer resource for an M2M terminal requesting to access by the core network side equipment when the M2M terminal in the MTC group is accessed to an evoluted package core (EPC). The invention also discloses a data transmission method which comprises the following steps of: allocating the group public bearer resource for the M2M terminal requesting to access by the core network side equipment; and creating and storing the corresponding relationship between the wireless access network bearer channels of all M2M terminals in the MTC group and the group public bearer resource and executing data uplink and downlink transmission according to the corresponding relationship by the core network side equipment. In the invention, the problem that a large quantity of network resources are occupied when the large-size M2M terminal is accessed to the network is solved.

Description

technical field [0001] The present invention relates to bearer establishment technology in mobile communication, in particular to a common bearer establishment method, data transmission method and core network side equipment. Background technique [0002] In recent years, machine-to-machine communication (M2M, Machine to Machine) services have gradually begun to be applied, such as logistics systems, remote meter reading, smart home and other applications. M2M service providers use existing wireless networks, such as General Packet Radio Service (GPRS, General Packet Radio service) networks, Evolved Packet System (EPS, Evolved Packet System) networks, etc., to carry out M2M services. Since there are obvious differences between the M2M service and the human-to-human (H2H, Human to Human) service, it is necessary to optimize the existing network to obtain the best network management and network communication quality. [0003] The current network of the 3rd Generation Partners...
