Access method, apparatus, and system

A wireless communications system, comprising:

• a first network device corresponding to a first micro device, wherein one or more first micro cells provided by the first micro device corresponds to a first coverage area;
• a second network device corresponding to a second micro device, wherein one or more second micro cells provided by the second micro device correspond to a second coverage area;
• and
• wherein:
• the first network device is configured to:
• configure, using the first micro device, the one or more first micro cells for a terminal device or a terminal device group comprising the terminal device, wherein the one or more first micro cells provide a service for only the terminal device or the terminal device group, and after the terminal device accesses the one or more first micro cells, and the first network device determines that the terminal device moves from the first coverage area to the second coverage area, send information corresponding to the terminal device and information corresponding to the one or more first micro cells to the second network device;
• and
• the second network device is configured to:
• configure the one or more second micro cells for the terminal device based on the information corresponding to the terminal device and the information corresponding to the one or more first micro cells, provide the one or more second micro cells for the terminal device using the second micro device, keep a parameter used to trigger a handover procedure unchanged, and maintain a connection between the one or more second micro cells and the terminal device based on configuration information of the one or more second micro cells.

A terminal device, comprising:

• a receiving circuit configured to receive, from a network device, configuration information of one or more micro cells, the one or more micro cells are configured for the terminal device or a terminal device group comprising the terminal device, and the one or more micro cells provide a service for only the terminal device or the terminal device group;
• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• accessing the one or more micro cells based on the configuration information received by the receiving circuit;
• and
• maintaining a connection between the terminal device and the one or more micro cells based on the configuration information of the one or more micro cells, wherein a Parameter used to trigger a handover procedure is kept unchanged.
