Abstract
This application provides a network access method, an access device, and a terminal device. The access device is connected to at least two different types of core networks. When the terminal device is to connect to a core network, the terminal device sends, to the access device, a first message used to indicate a type of the terminal device. The access device determines the type of the terminal device based on the first message, and determines, based on the type of the terminal device, a target core network to be connected by the terminal device, so that the access device accurately connects the terminal device to the target core network.
Claims15
A method of network access, comprising:
- receiving, by an access device from a terminal device, a first message used to indicate that the terminal device is a first-type terminal device, the first-type terminal device has a capability of accessing a first core network, the access device is connected to two different types of core networks, the two different types of core networks are a New Radio Access Technology (NR) system and a Long Term Evolution (LTE) system and the two different types of core networks comprise the first core network;
- determining, by the access device based on the first message, that a type of the terminal device is the first type;
- and
- determining, by the access device based on the type of the terminal device, that a target core network to be accessed by the terminal device is the first core network so that when in which the LTE system and the NR system coexist, the access device accurately connects the terminal device to the respective target core network,
- wherein the first message is a preamble sequence, and the determining, by the access device based on the first message, that a type of the terminal device is a first type comprises:
- determining, by the access device based on a correspondence between the preamble sequence and the first-type terminal device, that the type of the terminal device is the first type.
