Abstract:
A data processing method is provided for forwarding data in the case of handover between heterogeneous networks. The data processing method includes: when a user equipment (UE) is handed over from an originating network to a target network, receiving, by the originating network, a data forwarding address obtained by the target network; creating a data forwarding tunnel between an originating network gateway and a target network gateway according to the data forwarding address; and forwarding data to the target network through the data forwarding tunnel. A data processing device is also provided. The lossless data processing solution can overcome the problem of data loss in the case of handover between heterogeneous networks in the existing technology, reduces the time of user service interruption and enhances the user experience.

Embodiments of the present invention relate to a method and device for handling a failure of a mobility management device in an ISR activated scenario. The method includes: detecting, by a serving gateway, a failure of a first mobility management device; and when the serving gateway receives downlink user plane or control plane data of a user equipment, paging, by the serving gateway, the user equipment using a downlink data notification message including identity information of the user equipment, in a first radio access network connected to the first mobility management device.
Abstract:
Embodiments of this application provide a multicast/broadcast service communication method, an apparatus, and a system. The method includes: a first terminal device receives first information, where the first information indicates activation or release of a first multicast/broadcast session, the first terminal device joins the first multicast/broadcast session, the first terminal device is in a radio resource control inactive state, and the first multicast/broadcast session is used for transmitting a first multicast/broadcast service; and the first terminal device enters a connected state or keeps in the radio resource control inactive state based on the first information. According to the method, a terminal device that is in a radio resource control inactive state and that is allowed to receive a multicast/broadcast service in this state does not enter a connected state, thereby helping reduce network overheads.
Abstract:
Embodiments of this application disclose a communication method, apparatus, and system. An example communication method includes: receiving, by an access network device from an access and mobility management function network element, information indicating to activate a multicast session corresponding to a multicast service; and sending, by the access network device based on the information, a paging message to a terminal in a radio resource control_inactive (RRC_inactive) state in the multicast session corresponding to the multicast service.
Abstract:
A route configuration method includes determining, by a session management network element, that a first terminal in a first group is allowed to communicate with a second terminal in a second group. The route configuration method further includes sending, by the session management network element, first forwarding information to a first user plane network element. The first user plane network element is configured to provide a service for the first terminal. The first forwarding information is useable by the first user plane network element to forward a first packet. The first packet is to be sent by the first terminal to the second terminal.
Abstract:
The technology of this application relates to a communication method and apparatus, to resolve a current problem that limited bandwidth resources of a single link affect quality of service. In an example embodiment, a terminal sends a first access message to an access gateway in a second core network through a first network, and sends a second access message to the access gateway through a second network, where the first access message is encapsulated by using a first IP address. Further, the access gateway requests an AMF network element to establish two communication links for the terminal. One communication link is for the terminal to access the core network through the first network, and the other communication link is for the terminal to access the core network through the second network. Through establishment of the two communication links between the terminal and the core network, bandwidth resources can be added, and the quality of service can be improved.
Abstract:
This application provides a communication method and an apparatus. The method includes: An access management network element receives a registration request from a terminal device, and the access management network element obtains configuration type indication information, determines, based on the configuration type indication information, to perform restricted registration, and starts a restricted registration timer. After the restricted registration timer expires, the access management network element initiates a deregistration procedure to deregister the UE from a network. By using the method, the terminal device can be prevented from maliciously camping or accessing another service for a long time. In addition, this solution is simple to implement, and easy to deploy and implement.
Abstract:
This application provides a communication method and a communications device. The method includes: obtaining a media access control (MAC) address that is of a terminal device and that is bound to a session and first route information of an interface, corresponding to the session, between a user plane function network element and a data network; and sending to an application function network element or a gateway of the data network, the MAC address that is of the terminal device and that is bound to the session and the first route information.
Abstract:
A method for control of an unmanned aerial vehicle includes: determining, by UTM, that a control device of an unmanned aerial vehicle UAV is to be handed over; and sending, by the UTM, a hosting command to a network device, to enable the network device to indicate, according to the hosting command, that the UAV is to hand over the control device of the UAV, where the hosting command is used to hand over the control device of the UAV, and the hosting command includes indication information used for handing over the control device of the UAV and information about the UAV. In this way, the UTM controls a connected UAV and a control device of the UAV by using a communications network.
Abstract:
A communication method and apparatus. According to the communication method, a session management function (SMF) receives a first message sent by a first terminal apparatus. The first message is used to request the SMF to establish a first session for the first terminal apparatus. The first message is further used to indicate that the first session is used for communication between the first terminal apparatus and a second terminal apparatus. The first terminal apparatus and the second terminal apparatus belong to a same unmanned aerial vehicle communication system. Then, the SMF sends address information of the first terminal apparatus to a first management network element based on the first message. This provides a possibility of exchanging address information of terminal apparatuses in an unmanned aerial vehicle communication system.
