A network device functioning as an ingress tunnel router facilitates multicast traffic forwarding and mobility in a network with mobile devices by receiving data traffic to broadcast to a multicast group, querying a locator identifier separation protocol (LISP) mapping system to get a list of routing locators (RLOCS) for members of the multicast group, constructing a bit indexed explicit replication (BIER) bitmap of the RLOC, and forwarding data traffic for the multicast group using the BIER bitmap. Whereas a network device functioning as an egress tunnel router supports handover processes by receiving a join for a multicast group from a subscriber node, registering interest in the multicast group with the LISP mapping system, receiving data traffic using a BIER bitmap identifying the egress tunnel router, and forwarding the multicast group data traffic to the subscriber node.

Embodiments relate to the field of communications technologies, and specifically, to a mobility management method, an apparatus, and a system. Embodiments of the present invention provide the mobility management method, the apparatus, and the system. When a primary cell of user equipment is changed, a change of the primary cell is performed through modification but not through conventional handover, so that data transmission is uninterrupted when the primary cell is changed.

A user entity (UE) such as a smartphone is configured to connect to both WiFi 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 WiFi (VoWiFi). When the UE is connected to VoWiFi and roaming from a first WiFi access point to a second WiFi 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 WiFi access point.

Provided are a path switching method and a terminal device. The terminal device has a packet data convergence protocol (PDCP) layer, the PDCP layer being able to send uplink data to a first cell group or a second cell group, the first cell group and the second cell group being different cell groups, the PDCP layer currently sending the uplink data to the first cell group; the method comprises: the terminal device enabling the switching of the PDCP layer from sending the uplink data to the first cell group, to sending the uplink data to the second cell group; and the terminal device sending first uplink data to the second cell group, the first uplink data at least including first data, the first data referring to the data that the terminal device has sent to a radio link control protocol (RLC) layer of the first cell group.

A wireless device may send a request to one or more wireless networks to download content associated therewith (e.g., currently playing, on a play list for future consumption). Request may be sent when wireless device is remote from one or more wireless networks or when wireless device is connected to wireless network and available bandwidth is limited. Request may include information about content, current playback position of content, and location of wireless device. Wireless network may receive request and determine an estimated arrival time for wireless device and an estimated playback location for currently-playing content. Wireless network may download content from content provider off line and store content in storage device connected to wireless network. Wireless device may access stored content when connected to wireless network and play content from storage or copy content thereto.

One embodiment of the present invention provides an apparatus comprising a transceiving unit and a control unit, and a communication method using the same, wherein the transceiving unit is configured to perform communication with at least one network node in a macro cell, the macro cell comprising at least one small cell and communicating in an FDD mode, and wherein the control unit is configured to control the small cell to communicate in a TDD mode, generate control information for preventing the occurrence of handover when a terminal moves between the small cells within the macro cell, and perform control to transmit the control information to the terminal.

A method for communication beam transition in a communication system includes sending beam information on a first communication beam, receiving a beam switch command on the first communication beam, the beam switch command requesting a transition from the first communication beam to a second communication beam, simultaneously sending and receiving information on the first communication beam and the second communication beam, and ceasing sending and receiving information on the first communication beam when transition to the second communication beam is completed.

Apparatuses, systems, and methods for a wireless device to perform enhanced duplication handling and/or failure handling procedures with a network, including one or more base station. The wireless device may connect to a network using multiple paths. The wireless device may autonomously determine whether to duplicate one or more transmissions to the network on the multiple paths. In the event of a radio link control failure associated with one bearer, the wireless device may suspend transmission of the failed bearer while continuing to use one or more other bearers for transmission.

A system for connection channel adaption using robotic automation is provided. The system comprising a first processing device configured to: establish a first communication channel with a user device associated with the user; receive, via the first communication channel, a first user input from the user on the user device for interacting with an entity platform; train a robotic process automation module based on the first user input, wherein the robotic process automation module is trained to execute the first user input on the entity platform via one or more communication channels; based on detecting the termination of the first communication channel, automatically establish the second communication channel with the user device; and execute the first user input on the entity platform, wherein the robotic process automation module simulates the first user input with a user interface by interacting directly with a presentation layer of the entity platform.

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.
