[Object] To make it possible to further increase a possibility of a success in a handover. [Solution] A first apparatus of the present invention includes: a first communication processing unit configured to transmit reference signals using beamforming; and a second communication processing unit configured to receive a handover message from a source base station of a handover of a terminal apparatus.

The first communication processing unit is configured to receive an access signal of the terminal apparatus based on the beam related information.

Systems, methods, and computer-readable media for preserving source host context when firewall policies are applied to traffic in an enterprise network fabric. A data packet to a destination host from a source host can be received at a first border node instance in an enterprise network fabric as part of network traffic. The data packet can include a context associated with the source host. Further, the data packet can be sent to a firewall of the enterprise network fabric and can be received at a second border node instance after the firewall applies a firewall policy to the data packet. The data packet can then be selectively encapsulated with the context associated with the source host at the second border node instance for applying one or more policies to control transmission of the network traffic through the enterprise network fabric.

The embodiments of the present disclosure provide a method and apparatus for distinguishing between data formats, and a communication device. The method includes a terminal receives a downlink data packet, and determines whether the data format of the downlink data packet is a first data format or a second data format, wherein the first data format indicates that the downlink data packet is encrypted using a first key of a source base station and/or compressed using a first header compression format of the source base station, and the second data format indicates that the downlink data packet is encrypted using a second key of a target base station and/or compressed using a second header compression format of the target base station.

[Object] To make it possible to further increase a possibility of a success in a handover.

[Solution] A first apparatus of the present invention includes: a first communication processing unit configured to transmit reference signals using beamforming; and a second communication processing unit configured to receive a handover message from a source base station of a handover of a terminal apparatus. The handover message includes beam related information related to a beam. The first communication processing unit is configured to receive an access signal of the terminal apparatus based on the beam related information.

In a communication method, a first access network device sends first information to a second access network device, where the first information is used to indicate that the first access network device has notified a core network device that a quality of service requirement of at least one quality of service flow cannot be met; the second access network device may send second information to the core network device, where the second information is used to notify the core network device that a quality of service requirement of a first quality of service flow in the at least one quality of service flow can be met, and the first quality of service flow is a quality of service flow that has been handed over from the first access network device to the second access network device.

The present disclosure relates to a 5.sup.th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4.sup.th generation (4G) communication system such as long-term evolution (LTE). According to various embodiments of the present disclosure, provided is a method for operating a network node such as an application function (AF) node in a wireless communication system, the method comprising the steps of: generating an AF request including information related to one or more data path latencies; and transmitting the information related to the one or more data path latencies to a session management function (SMF) node through a network exposure function (NEF) node.

A wireless communication method is provided to comprise: receiving, by a first computing device, a notification that a wireless communication device that has previously established a protocol data unit session via a first network access has registered for a second network access; and establishing, by the first computing device, one or more quality of service (QoS) flows for the protocol data unit session for the wireless communication device over the second network access by transmitting, to a second computing device, a message that includes information to associate the one or more quality of service (QoS) flows with the second network access, and wherein the first computing device is configured to carry out a session management function and the second computing device is configured to carry out an access and mobility management function.

A first base station (1) is configured to send, to a second base station (2), first configuration information that is necessary to establish a data bearer and a data radio bearer in the second base station (2) for a C/U-plane split scenario. Further, the first base station (1) is configured to send, to a third base station (3), configuration information (e.g., LPN information) regarding the data bearer established in the second base station (2) when a mobile station (4) moves from a first cell (10) to a third cell (30) (S103 and S104). It is thus, for example, possible to contribute to a reduction in wasted signaling when a UE moves between cells in the C/U-plane split scenario.

A communication method and apparatus, and a storage medium are provided, to resolve a problem in a conventional technology of discontinuity of a multicast/broadcast service of a UE during handover. The method includes: A target access network device receives first multicast/broadcast service data from a source access network device and second multicast/broadcast service data from a core network device; and if determining that the first multicast/broadcast service data is synchronous with the second multicast/broadcast service data, the target access network device sends the second multicast/broadcast service data to a terminal device, so that the continuity of the multicast/broadcast service of the UE during handover is ensured as much as possible.
