Title:

INFORMATION TRANSMISSION METHOD AND COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/155174

Kind Code:

A1

Abstract:

Provided in the present application are an information transmission method and a communication device. The method comprises: a first access network device receiving first information from a core network device, wherein the first information is used for the first access network device to determine a context of a terminal device; the context is used for the first access network device to send downlink data to the terminal device; and the context is suspended; the first access network device determining the context according to the first information; and the first access network device sending the downlink data to the terminal device according to the context. According to the information transmission method provided in the present application, the core network device notifies the first access network device of first information used for the first access network device to determine the context of the terminal device. The first access network device can restore the context of the terminal device according to the first information, so that when the downlink data sent by the core network device is received, the downlink data can be sent to the terminal device according to the context. The downlink data can be sent to the terminal device earlier, thereby reducing the power consumption overheads for the terminal device to receive the downlink data, and improving the efficiency and reliability of downlink data transmission, and thus improving communication efficiency.
