Abstract

Embodiments of the present invention provide a machine-type communication method and system. Operation capabilities of a machine are determined through a negotiation between the machine and a network (101); and the machine communicates with the network based on the determined operation capabilities (102). By adopting a negotiation mechanism, costs of a machine-type communication are reduced. Embodiments of the present invention further provide a cell search method and device. Transmission parameters for a cell are pre-configured for a device fixed in the cell; the device directly matches the cell using the pre-configured transmission parameters; and the device directly receives data in the case of a successful match. By adopting a machnism of pre-configuring transmission parameters, a cell search process is simplified, and utilization of resources is improved.
