Abstract: A resource migration method and apparatus are provided, so that a terminal device can change, according to a specific condition, an SFE serving the terminal device. The method includes: determining, by a terminal device, that a service function entity SFE serving the terminal device needs to be changed to a first SFE; acquiring information about a location of a resource/subresource corresponding to the terminal device in a second SFE, where the second SFE saves the resource/subresource corresponding to the terminal device; and sending, to the first SFE, a first identifier and the information about the location in the second SFE, where the first identifier is used to indicate that the terminal device needs to change the SFE serving the terminal device, so that the first SFE transfers, after receiving the first identifier, the resource/subresource corresponding to the terminal device from the second SFE to the first SFE.

Abstract: In a method, after a terminal is handed over from a home network to a redundant network, the terminal receives a value of a periodic network detection timer that is sent by a handover module. The value of the periodic network detection timer is determined by a subscription management device according to a policy and sent to the handover module, or the value of the periodic network detection timer is preset by the handover module. The terminal periodically detects signal strength of the home network of the terminal according to the value of the periodic network detection timer. If it is detected that the signal strength of the home network of the terminal is restored, a home network restoration report is sent to the handover module.
