Abstract: The present disclosure relates to paging methods and apparatus. One example method is applied to a first access network device. The first access network device belongs to a first network, a second access network device belongs to a second network, and the first network may be different from the second network. When UE accesses the first network and downlink data of the second network arrives, the UE may receive the data of the second network. The first access network device receives downlink data of a terminal from a first core network device, where the first core network device belongs to the first network.

Abstract: A radio resource adjustment method includes: receiving a network quality optimization request, sent by a path planning device, carrying a travel path and an estimated moment corresponding to a target location on the travel path through which a mobile terminal passes; matching the travel path with a coverage area of a base station, to determine a base station set to which a signal covering the travel path belongs; generating an optimization policy including configuration information for configuring a radio resource of the base station set based on the corresponding estimated moment; and sending an adjustment command to the network element management device based on the optimization policy, so that the network element management device instructs, based on the adjustment command, a target base station in the base station set to adjust allocation of the radio resource at the estimated moment.

Abstract: A data packet verification method and a device improve network security. The method includes: receiving a data packet of a terminal device, where the data packet carries a first token and a service identifier, and the service identifier is used to indicate a type of a service to which the data packet belongs; obtaining first input information based on the data packet, and generating a second token based on the first input information, where the first input information includes an identifier of the terminal device and the service identifier carried in the data packet; and sending the data packet when the first token is the same as the second token.

Abstract: A paging method, a paging device, and system are described. A mobility management network element (MME) obtains location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network, where the UE already accesses the non-3GPP network. The MME receives a downlink data notification message, where the downlink data notification message carries an identifier of the UE. The MME pages the UE according to the location information of the UE in the non-3GPP network. In some implementations, a paging range may be determined according to the location information of the UE in the non-3GPP network, and a paging message does not need to be sent to all base stations in a registration area of the UE.

Abstract: An embodiment of the present invention provides an access method in a wireless communications network. Authentication and authorization functions of a 3GPP AAA server for a non-3GPP access network can be integrated into a mobility management network element. Therefore, after UE accesses the non-3GPP access network, a non-3GPP access gateway may select the mobility management network element that supports the authentication and authorization functions for the non-3GPP access network as a target mobility management network element, and request the target mobility management network element to perform authentication and authorization for the UE. After authentication and authorization are performed for the UE, the non-3GPP access gateway may select a P-GW for the UE, and set up a PDN connection between the non-3GPP access gateway and the selected P-GW for the UE.

Abstract: A network access method and apparatus for improving network access accuracy of a terminal device are disclosed. A first network element (for example, an access management network element (for example, access and mobility management function (AMF) network element or a mobility management entity (MME) network element) or a unified data management (UDM) network element) obtains an access request including access location information of a first terminal device; obtains subscription information including subscription location information of the first terminal device; in response to confirming that the access location information of the first terminal device does not belong to the subscription location information, obtains permission information for permitting the first terminal device to access a network at an access location corresponding to the access location information; and permits, based on the permission message, the first terminal device to access the network at the access location corresponding to the access location information.

Abstract: This application provides a network handover method and an apparatus. Before a terminal device is handed over from a first network to a second network, the terminal device sets up a first tunnel to a first interworking device, where a communication identifier, of the terminal device, in the first tunnel is a first identifier the first identifier is an identifier used in the first network by the terminal device, and the first interworking device is an interface device in the first network and oriented toward a network other than the first network. After the terminal device is handed over from the first network to the second network, the terminal device sends an update request to the first interworking device, where the update request request to update the communication identifier to a second identifier, and the second identifier is an identifier used in the second network by the terminal device.

Abstract: The present disclosure relates to handover methods, apparatus, and communications systems. One example method includes sending, by a source access point device, a first message to a target access point device through an access control device, and sending a second message to a terminal device, where the first message is used to notify the target access point device that the terminal device is prepared to be handed over to the target access point device, arid the second message is used to instruct the terminal device to be handed over to the target access point device.

Abstract: A method and an apparatus for determining a status of a terminal device, and a device are disclosed. The method includes: obtaining, by an access and mobility management network element, an access type used by the terminal device to access a network, where the access type includes at least one of 3rd generation partnership project (3GPP) access and non-3GPP access; and determining, by the access and mobility management network element based on a status of the terminal device in the access type, the status of the terminal device, where the status of the terminal device includes at least one of a loss-of-connectivity state and an available-to-connectivity state. By using the method according to the embodiments of the present disclosure, accuracy of determining the status of the terminal device is improved.
