A multicast data transmission method, device, and system in which a core network control plane device receives a multicast message from a core network user plane device, the multicast message carries an identifier of a source terminal device sending multicast data and an identifier of a target multicast group to which the source terminal device belongs; and sends an identifier of a target access network device that is to receive the multicast data to the core network user plane device based on the identifier of the source terminal device, the identifier of the target multicast group, and a first multicast table.

Methods, systems, and devices for wireless communications are described that provide a handover may be performed based on one or more conditions at a UE and in conjunction with a handover procedure from a source base station to a target base station. The one or more conditions at the UE may be associated with successful establishment or maintenance of the second connection. In some cases, the one or more conditions at the UE may correspond to one or more measurements associated with the source base station, the target base station, one or more neighboring base stations, or any combinations thereof.

In a terminal handover method, a controller sends a radio identifier and a control channel resource of a terminal that are configured by the controller to the terminal. When the terminal is located in a coverage area of a first base station, the controller sends the radio identifier and the control channel resource of the terminal to the first base station. The controller determines that the terminal is located in a coverage area of a second base station, and sends the radio identifier and the control channel resource of the terminal to the second base station. The terminal receives the control signalling sent from the first base station and the second base station separately by using the control channel resource.

A user entity (UE) such as a smartphone is configured to connect to both Wi-Fi and a Long Term Evolution (LTE) cellular network for voice and data services. For voice, the UE supports both Voice over LTE (VoLTE) and Voice over Wi-Fi (VoWiFi). When the UE is connected to VoWiFi and roaming from a first Wi-Fi access point to a second Wi-Fi access point, the UE and Mobility Management Entity in the cellular network carry out a preparatory handover to VoLTE to prevent service loss in the event of an unsuccessful VoWiFi connection from the second Wi-Fi access point.

A wireless device receives configuration parameters from a base station. The configuration parameters are for a first session and a second session. The second session is for a packet duplication of the first session. The wireless device receives an activation indication of the packet duplication. Based on the activation indication of the packet duplication, the wireless device sends packets of the first session to a user plane function and a duplication of the packets to the user plane function via the second session.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure discloses a system, a data transmission method and a network equipment supporting a Packet Data Convergence Protocol (PDCP) duplication function. The data transmission method supporting a PDCP duplication function comprises the steps of: transmitting, by a first network equipment, a configuration instruction message of a radio bearer supporting a PDCP duplication function to a second network equipment; and, performing, by the first network equipment and the second network equipment, transmission of a data packet of the radio bearer configured with the PDCP duplication function. In the present disclosure, by an interface between the first network equipment and the second network equipment, the transmission of duplicated data packets between the first network equipment and the second network equipment is realized, and the reliability of data transmission is improved. The present disclosure also discloses a method and device for transferring supplementary uplink carrier configuration information and a method and device for performing a connection mobility adjustment.

A control plane of a network, including radios of a radio access network controlled by the control plane and user plane functions controlled by the control plane, establishes first and second protocol data unit (PDU) connections each to handle the same flows of traffic for ultra-reliable low latency communications (URLLC) from user equipment to a data network through first and second source radios, respectively. Due to mobility of the user equipment, the control plane relocates the flows from the first and second source radios to first and second target radios, respectively. To relocate the flows, the control plane receives from the first target radio a notification that identifies flows that cannot be activated on the first target radio. In response to the notification, the control plane commands the first target radio to prioritize the flows that cannot be activated above remaining ones of the flows.

Embodiments of the present invention are directed to providing connection channel adaption using robotic automation. The invention leverages a robotic process automation module to generate an operation record based on previous user device input in order to automatically recover and continue a previous interaction with an entity platform conducted over a terminated connection channel. The system automatically establishes a new connection channel upon determining the initial channel termination while retaining previous user input interaction progression within the entity platform. Further, the module may be configured to transform the user input to be compatible with the new connection channel allowing for seamless continuation of the interaction to minimize downtime.

A method includes receiving, at a first wireless bridge device, a first packet and determining whether the first packet is a first type or a second type. If the first packet is the first type, the first packet is duplicated to generate two duplicated packets. A first one of the duplicated packets is forwarded to a second wireless bridge device via a tunnel between the first wireless bridge device and the second wireless bridge device. A second one of the duplicated packets is forwarded to one or more access points via a first wireless link between the first wireless bridge device and the one or more access points. If the first packet is the second type, the first packet is forwarded to the second wireless bridge device via the tunnel or forwarding the first packet to the one or more access points via the first wireless link.

The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.
