Disclosed is technology for applying a more differential QoS, that is, service quality to each communication service by implementing a differential QoS control in a radio section more precisely without any increase in complexity and load compared to a conventional bearer based QoS control method.

A method for communicating between base stations of two different wireless communication networks may include (1) transmitting a setup request message from a first base station of a first wireless communication network to a second base station of a second wireless communication network, the setup request message including a first user equipment (UE) device context format of the first wireless communication network and a second UE device context format of the second wireless communication network; (2) receiving, at the first base station, a setup response from the second base station, the setup response including a union of the first UE device context format and the second UE device context format; and (3) at the first base station, communicating with the second base station according to the union of the first UE device context format and the second UE device context format.

Disclosed are systems, apparatuses, methods, and computer-readable media to address bearer loss during inter-radio access technology (RAT) handovers. A method includes sending a create bearer request for establishing a service for the mobile device using a first connection; receiving a create bearer response message to setup a second connection for the mobile device to continue the service; and, in response to the create bearer response message, sending an update bearer request message to provide the mobile device with the QoS information associated with the second connection, the QoS information allowing the mobile device to verify an existing QoS flow to continue the service after the handover. In some cases, a user equipment (UE) may delete a mapping between a QoS information when a previous message does not include an evolved packet core (EPC) bearer indicator (EBI) that identifies QoS policies.

A data exchange method includes: receiving a first measurement report sent by user equipment UE, where the first measurement report includes a neighboring cell physical cell identifier PCI of an intra-frequency neighboring cell; determining, based on the neighboring cell PCI, configuration information corresponding to the intra-frequency neighboring cell, where the configuration information indicates a first time-frequency domain position of a resource element RE carrying a target signal; sending a first indication message to the UE based on the configuration information, where the first indication message is used to indicate the UE to set to skip, when receiving PDSCH data, performing data channel demodulation on the RE corresponding to the first time-frequency domain position; and setting, based on the configuration information, to forbid carrying, when delivering the physical layer downlink shared channel PDSCH data to the UE, the PDSCH data on the RE corresponding to the first time-frequency domain position.

Embodiments of this application provide communication method and related devices. In an example method, a first IAB-donor-central unit (CU) determines a quality of service (QoS) attribute corresponding to an F1 application protocol (F1AP) message, where an F1 interface is a communication interface between the first IAB-donor-CU and a distributed unit (DU) of an IAB-node. Then, the first IAB-donor-CU sends the F1AP message and the QoS attribute corresponding to the F1AP message to a second IAB-donor-DU.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The method comprises receiving, from an access and mobility management function (AMF), a handover request message including E-UTRAN radio access bearer (E-RAB) information and quality of service (Qos) flow information, identifying whether a protocol data unit (PDU) session is accepted or not, determining whether a data forwarding for at least one Qos flow associated with the PDU session is accepted or not based on the E-RAB information and the Qos flow information in case that the PDU session is accepted and transmitting, to the AMF, a handover request acknowledgement message including information on the at least one Qos flow based on the determination. The method solves the data forwarding problem during the movement of a UE between an LTE system and a 5G system, so that the loss of data is avoided and the continuity of services is ensured.

This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.

Provided in embodiments of the present disclosure a QoS processing method and a QoS processing device. The QoS processing method includes transmitting, by a target base station, a first message to a source base station. The first message at least comprises first information and second information; the first information is configured for notifying the source base station that the target base station is incapable of meeting a QoS requirement on one or more flows of a UE; and the second information is information of a QoS parameter capable of being accepted by the target base station and recommended with respect to the one or more flows.

Certain aspects of the present disclosure provide techniques for beam management for make-before-break (MBB) handover. A method that may be performed by a user equipment (UE) includes establishing a first cell connection with a first base station (BS) while maintaining an existing second cell connection with a second BS, and determining that a first transmission time of a first signal transmitted by the first BS is less than a threshold time duration from a second transmission time of a second signal transmitted by the second BS. In some examples, the first signal is associated with one or more first communication metrics and the second signal is associated with one or more second communication metrics, wherein each of the one or more first communication metrics and the one or more second communication metrics comprise one or more quality of service (QoS) metrics.

A communication method enables a base station to allocate a radio resource to a data packet of a time sensitive networking (TSN) network in a scenario in which the TSN network transmits the data packet through a 5G network. The method includes: obtaining, by an access network device, a first traffic pattern, and allocating a radio resource to a first traffic based on the first traffic pattern. The first traffic pattern includes time information of the first traffic with respect to a first clock. The first clock is a clock used by a first network. The access network device belongs to the first network. The time information includes a time point and/or a period at/in which a data packet of the first traffic arrives at the first network.
