Abstract: A method to reduce signaling interaction in an access process of a terminal includes: receiving, by a convergent network device, an access request message from a first access device on a first network, where the access request message carries a first globally unique temporary identity (GUTI) of a terminal, which is an old GUTI on the first network or a GUTI on the first network and obtained by mapping a second GUTI on a second network; determining, by the convergent network device, a first target context of the terminal on the first network based on the first GUTI and a device identifier corresponding to the convergent network device when serving as a mobility management device; and sending, by the convergent network device, an access response message to the first access device to indicate that the terminal has successfully accessed the first network.

Abstract: A converged network device: receives a handover requirement from a first access device in a first network, where the handover requirement carries an identifier of a second access device in a second network or an identity of a tracking area served by the second access device; determines, based on the identifier of the second access device or the identity of the tracking area served by the second access device, that the second access device is managed by the converged network device; sends a handover request to the second access device, where the handover request is used to request the second access device to prepare a related resource for the terminal; sends a handover command to the first access device, where the handover command is used to instruct to hand over the terminal to the second access device; and receives a handover notification from the second access device.

Abstract: A communication method and a communications device, where the communication method includes: When a user equipment roams from a first network to a second network, a first core network device receives a first request, where the first request is a user authentication request or an authentication data request, where the first request carries an authentication vector request indication, where the second network is a 5G standalone network, where the first network is a 5G non-standalone network, and where the first core network device is in the first network. The first core network device generates an authentication vector quintet based on the authentication vector request indication, where a 0th bit of an authentication management field in the authentication vector quintet is set to 1. The first core network device sends a response to the first request, where the response to the first request carries the authentication vector quintet.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for determining gateway information. A first device obtains first information of user equipment, where the first information of the user equipment is used to indicate an area in which the user equipment subscribes to a service, and the first device determines gateway information corresponding to a first domain name, where the first domain name includes the first information of the user equipment. The first domain name includes the first information of the user equipment, and the first information is used to indicate the area in which the user equipment subscribes to the service. Compared with a method in which a number segment is used to generate a domain name, this reduces a quantity of domain names that need to be configured and maintained, and reduces maintenance costs of an operator.
