Disclosed is a design and implementation of a Wi-Fi based network (e.g., roadside hotspot network designed to operate at vehicular speeds and picocell, meter-sized, cells). The disclosed access points (APs) make delivery decisions to the vehicular clients they serve at millisecond-level granularities, exploiting path diversity in roadside networks. In order to accomplish this, buffer management algorithms are employed that allow participating APs to manage each other's queues, rapidly quenching each other's transmissions and flushing each other's queues. An example embodiment of the disclosed approach employs an eight-AP network alongside a nearby road, and was evaluated with mobile clients moving at up to 25 mph. Depending on mobility speed, the disclosed approach achieves a 2.4-4.7 times TCP throughput improvement over a baseline fast handover protocol that captures the state of the art in Wi-Fi roaming, the IEEE 802.11k and 802.11r standards.

There is provided a method, and a network node for implementing the method, in a cellular telecommunications network. The cellular telecommunications network includes a first and second base station, the first base station having a first interface for communicating with a first cellular core networking node and a second interface for wirelessly communicating with the second base station, the second base station being mobile and having a first interface for wirelessly communicating with the first base station and a second interface for communicating with a User Equipment (UE), wherein the UE's user traffic is transmitted between the first cellular core networking node and the UE via the first and second base stations.

A cache generation instructing section of a mobile station transmits, as a download instruction, an instruction that downloads a data fragment distributed to a mobile body when the mobile body is traveling in a communication area from a contents server. In addition, a cache generation section of a distribution cache node that manages data distribution in the communication area downloads the data fragment from a contents server based on the download instruction and stores the downloaded data fragment in a cache management database of a storage section as a cache.

According to a communication method and a communications apparatus, in a process in which an access network device serving a terminal is handed over from a source access network device to a target access network device, a user plane function network element may transmit first information to the source access network device. The first information is used to indicate that the user plane function network element bicasts downlink packets to the source access network device and the target access network device, so that after determining that a data packet received before the first information is sent to the terminal, the source access network device triggers an air interface handover, to avoid a packet loss in a handover process, or so that the source access network device synchronizes a PDCP SN of the source access network device with a PDCP SN of the target access network device.

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.

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.

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 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.

A system described herein may provide a technique for the handover of a User Equipment (UE) from a first Distributed Unit (DU) of a wireless network to a second DU in a manner that minimizes or interruption of the delivery of traffic to the UE. When the UE is attached to a first DU, one or more second DUs may be identified as candidates for attachment to the UE. The one or more second DUs may be pre-loaded with context information and/or traffic for the UE. In some embodiments, a third mesh DU (MDU) may be identified as a candidate for attachment to a first MDU that is attached to a second MDU. The third MDU may be pre-loaded with context information and/or traffic for the first MDU.

The method includes performing at least one of a first type transmission, a first type handover process on the PDU session, or the data stream in the PDU session. The first type of transmission includes at least one of the network side and the terminal side perform data copy type transmission on the data packet through multiple paths, or perform the first priority transmission on the data packet. The first priority transmission refers to that the transmitted data stream corresponds to a set of specific QoS parameters. The first type of handover process includes before the air interface data radio bearer is handover from the first base station to the second base station. The second core network element completes the establishment of a first path with the first base station and the establishment of a second path with the second base station. The first type of handover process also includes after the air interface data radio bearer is handover from the first base station to the second base station, the second core network element releases the first path with the first base station.
