Document Type and Number:
WIPO Patent Application WO/2019/134295
Kind Code:
A1
Abstract:
The embodiments of the present application provide a wireless communication method and device, being capable of implementing network conversion across systems in a flexible registration mode of a terminal device. The method comprises: a first network device in a first system determining a current registration mode of a terminal device and/or a supported registration mode, the registration mode being a single registration mode concerning registration in a single system or a dual registration mode concerning registration in a dual system, the terminal device having currently accessed a first cell in the first system; and the first network device determining, according to the current registration mode of the terminal device and/or the supported registration mode, a procedure that needs to be performed or cannot be performed by the terminal device for accessing a second cell in a second system.
