Redirection method, network and terminal device, communication system and readable storage medium

Abstract

The application discloses a redirection method, a first network device, a second network device, a terminal device, a communication system and a computer-readable storage medium. The redirection method is used for the first network device. The redirection method includes: receiving the first frequency point information sent by the second network device, the first frequency point information includes the first frequency point whose network deployment scheme supports dual connection; generating redirection information according to the first frequency point information; Orientation information is sent to the end device. In the redirection method in the embodiment of the present application, the first network device sends the redirection information generated by the second network device for the first frequency supporting dual connectivity according to the network deployment scheme to the terminal device, so that the terminal device can The redirection information is preferentially redirected to the frequency point of the target, thereby greatly improving the probability that the terminal device successfully accesses another wireless communication network through dual connections on one wireless communication network.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a redirection method, a first network device, a second network device, a terminal device, a communication system, and a non-volatile computer-readable storage medium. Background technique [0002] When the user equipment (User Equipment) communicates with a certain wireless communication network, if the strength of the signal sent and received between the user equipment and the current wireless communication network is weak, the network is congested, or a better wireless communication network needs to be provided for the user equipment, etc. In this case, the wireless communication network will send redirection information to the user equipment to inform the user equipment to access other wireless communication networks, so as to ensure that the user equipment can connect to the Internet normally. However, when the first wireless communication network (eg,...

Problems solved by technology

However, when the first wireless communication network (eg, 2G / 3G wireless communication network) notifies the user equipment to redirect to the second wireless communication network (eg, 4G wireless communication network), it may occur that the user equipment is redirected to the second wireless communication network. The frequency points that do not support the dual connectivity (such as EN-DC) function under the network, resulting in the situation that the user equipment cannot access the third wireless communication network (such as 5G wireless communication network)
