Abstract: Embodiments of the present invention provide a circuit switched fallback method and a user equipment. The method includes: sending a request message to an LTE network, where the request message is used for requesting a CS voice service from the LTE network, so that the LTE network sends a CS voice service fallback response message to a user equipment, where the CS voice service fallback response message is used for instructing the user equipment to perform CSFB from the LTE network to a GSM network; after the CS voice service fallback response message sent by the LTE network is received, acquiring a system message of a target cell in the GSM network; and camping on the target cell according to the system message and initiating a CS registration process according to the system message, to perform the CS voice service.

Abstract: Embodiments of the present disclosure provide a routing control method, network device, and controller. The method may include the network device obtaining a route suppression request. The method may also include determining the second routing entry. Furthermore, the method may include setting a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. In the method, the network device may have a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.
