摘要： Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

摘要： Embodiments of the present disclosure disclose a session management method and an apparatus. The technology is specifically related to sending, by user equipment, a NAS message to an AGF, where the NAS message includes a PDU session establishment request message used to request to establish a PDU session, receiving, by the user equipment, a PDU session establishment accept message returned by a network side device, and establishing, by the user equipment, an access session with the AGF, where the access session is an access session related to the PDU session. The user equipment sends the NAS message to establish the PDU session, and establishes the access session with the AGF. Because the access session is related to the PDU session, the user equipment can map the PDU session to the access session, so that the user equipment accesses a 5G CN through a fixed network.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to operate in a control mode. In some cases, the control mode may be an in active mode (e.g., a radio resource control (RRC) inactive mode). The UE may be configured to receive a control message from a network node. In some cases, the control message may include an uplink grant associated with a duration. The duration may relate to a timer, such as an expiration timer, for example. The UE may transmit an uplink transmission to the network node while operating in the control mode. The uplink transmission may be in accordance with the uplink grant and the duration. In some cases, prior to transmitting the uplink transmission, the UE may multiplex the uplink transmission with a second control message including an indication for the UE to remain in the control mode.

摘要： Apparatuses, methods, and systems are disclosed for reconfiguring a data connection using new parameters. One apparatus includes a transceiver that communicates with a UE and a processor that registers the UE with a mobile communication network using a first set of parameters, where the first set of parameters is based on a UE configuration. The processor identifies a second set of parameters to be used by the UE in the mobile communication network. Via the transceiver, the processor sends the second set of parameters to the UE and sends mapping information which indicates how the at least one parameter in the second set of parameters corresponds to at least one new parameter for the UE configuration.

摘要： The present disclosure provides a method and a device for cell handover, and a method for a terminal device to establish a PDCP entity during a handover process. The method includes: establishing a first Packet Data Convergence Protocol (PDCP) entity, the first PDCP entity being configured for communication between a terminal device and a target cell base station; and releasing a second PDCP entity, the second PDCP entity being configured for communication between the terminal device and a source cell base station. Time at which the second PDCP entity is released is not earlier than time at which the first PDCP entity is established.

摘要： A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.

摘要： During operation, a radio node may provide, at a transmit time during a first time interval, a first instance of a keep-alive message to a computer. Then, the radio node may receive, at a receive time prior to a first instance of a transmit expire time, an instance of a keep-alive response from the computer, where the instance of the keep-alive response authorizes the radio node to transmit in a granted portion of the spectrum until a second instance of the transmit expire time has elapsed. Moreover, the radio node may determine, based at least in part on the receive time and the first instance of the transmit expire time, an updated transmit time. Next, the radio node may provide, at the updated transmit time, which is prior to the second instance of the transmit expire time, a second instance of the keep-alive message addressed to the computer.

摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing so, signaling overhead and energy consumption within the wireless device (16) when operating in the long range extension mode is substantially reduced.

摘要： A data transmission method, a terminal, and an access-network network element are disclosed. An interface is disposed on a policy client of UE and an operating system or an application layer of the UE. The interface is used to provide the operating system or the application layer with a policy related to the operating system or the application layer, and collect, from the operating system or the application layer, information required for a report. In this way, a dedicated transport channel is implemented by a bottom layer of the UE, reports and policies are transmitted on the dedicated transport channel, and during implementation, a protocol is not coupled with the application layer or the operating system, so that the system is simple to implement.

摘要： Methods and techniques are described for efficiently supporting periodic and triggered location services for a user equipment (UE) in a Fifth Generation wireless network. A serving core network (CN) node, such as an AMF, receives a request for periodic or triggered location for the UE from another CN entity, such as a GMLC, and transfers the request to a location server, such as an LMF, which initiates and establishes the periodic and triggered location session with the UE. The serving CN node then releases all resources for the location request. The UE monitors for periodic or trigger events and reports each event to a location server which forwards an event report, optionally containing a UE location, to an external client via a CN entity, such as GMLC. The event reporting can be efficient because a serving CN node is not materially involved.
