Abstract:
This application discloses a network handover method and a network device, to resolve a problem that a terminal device cannot perform an IMS voice service. The method includes: receiving, by a first access network device, first session management information from a session management network element, where the first session management information is for requesting to set up a user plane tunnel for a voice service of a terminal device; and sending, by the first access network device, a handover request to a first mobility management network element based on the first session management information and a first condition, where the handover request is for handing over the terminal device from a first network to a second network, and the first condition includes that the voice service cannot be performed in the first network. This application is applicable to the field of communication technologies.

Claim (Index 11):
The network registration method according to  claim 10 , wherein the registration request carries indication information indicating that the terminal device is a voice service centric terminal device, and the determining that the terminal device is a voice service centric terminal device comprises:\n determining, by the first mobility management network element based on the registration request, that the terminal device is a voice service centric terminal device.
