摘要： A method for redirecting a user equipment (UE) from a first network to a second network is described. The method includes determining, at a wireless access point of the first network, information for the UE about one or more mobile network operator (MNO) networks. The method also includes selecting the second network for redirection from among the one or more MNO networks based on the determined information. The method further includes sending the UE a redirection message that redirects the UE from the first network to the second network.

摘要： Embodiments of this application relate to the field of communications technologies, and in particular, to a communication method and a communications apparatus. The solution includes: sending, by a source access network device, a first data packet of a terminal to a target access network device; and when the source access network device determines that the target access network device has received the first data packet, sending, by the source access network device, a first message to the terminal, where the first message is used to indicate the terminal to hand over to the target access network device.

摘要： In a first aspect, a communication method is used in a mobile communication system for supporting a multicast and broadcast service (MBS). The communication method includes: configuring, by a base station managing a first cell, a multicast radio bearer (MRB) including a Point-to-Multipoint (PTM) communication path for a user equipment in a radio resource control (RRC) connected state; switching, by the base station, from the PTM communication path to a Point-to-Point (PTP) communication path in response to determining handover of the user equipment from the first cell to a second cell; and executing, by the base station, the handover after the switching to the PTP communication path.

摘要： Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

摘要： A communication method includes a terminal device sending M compressed data packets. The M compressed data packets are obtained by compressing M data packets based on a first buffer. The terminal device reestablishes a PDCP layer without resetting the first buffer. The terminal device then sends N compressed data packets. The N compressed data packets are a part or all of the M compressed data packets. When reestablishing the PDCP layer, the terminal device does not reset the first buffer. In this case, if the terminal device needs to retransmit a data packet, the terminal device may retransmit a previously obtained compressed data packet, and does not need to compress the data packet again.

摘要： Various example embodiments relate to relate to network nodes (20A; 20B), methods and computer program products configured to hand over a communication link between a cell and user equipment (10) in a wireless communication network from a source cell (40A) to a target cell (40B; 40C). According to various, but not necessarily all, embodiments of the invention there is provided a node (20A), comprising: means configured to establish a communication link between a source cell (40A) and user equipment (10); means configured to transmit a series of data packets to the user equipment (10), each data packet comprising an associated sequence identifier; means to receive an acknowledgement of successful receipt of a data packet of the series by user equipment (10), the acknowledgement comprising an indication of the successfully received data packet sequence identifier; means configured to receive an indication of an identified handover target cell (40B; 40C); means configured to request handover of the user equipment (10) to the identified handover target cell (40B; 40C); means configured to receive an acknowledgement of handover request from the identified handover target cell (40B; 40C); and means to forward data packets to be transmitted to user equipment (10) to the identified target cell (40B; 40C), the forwarded data packets comprising the indication of associated sequence identifier and the most recent successfully received data packet sequence identifier. Also provided is a node (20B), comprising: means configured to receive a request for handover of user equipment (10) from a source cell (40A) to a target cell (40B; 40C); means configured to transmit an acknowledgement of handover request to the source cell (40A); and means to receive forwarded data packets forming a series of data packets to be transmitted to user equipment (10), the forwarded data packets comprising an indication of a sequence identifier associated with each forwarded data packet and an indication of a most recent successfully received data packet sequence identifier. Arrangements recognise that one way to mitigate some of the negative effects associated with early data forwarding, for example, the increased use of network memory and the risk of duplicate transmissions, is by providing a mechanism supported by a source (20A) and target node (20B) to allow a target access node (20B) to perform efficient data discarding.

摘要： A method is performed in a first infrastructure equipment for a handover of a wireless device from the first infrastructure equipment as a source to a second infrastructure equipment as a target. The method comprises maintaining a mapping between a plurality of packet bearers and a data radio bearer for the wireless device, each of the plurality of packet bearers being configured to provide a specified quality of service, determining that the wireless device should handover from the first infrastructure equipment to the second infrastructure equipment, determining that the second infrastructure equipment does not support the mapping of the plurality of packet bearers to the data radio bearer, and providing an indication of a mapping of the plurality of packet bearers for the second infrastructure equipment after handover to one of a core network equipment and the second infrastructure equipment.

摘要： A method performed by a target access node for handling data packets in a handover of a User Equipment, UE, from a source cell served by a source access node, to a target cell, served by the target access node in a wireless communications network is provided. The target access node receives a status report of last received data packet in the UE from the source access node. The target access node performs a data packet duplication check based on the information comprised in the status report. The target access node then sends to the UE, only data packets which have not already been received by the UE from the source access node, based on the outcome of the duplication check.
