Methods and apparatuses are provided in a wireless communication system. A first message is transmitted, from a master base station, to a secondary base station, for requesting the secondary base station to allocate resources for a dual connectivity (DC) operation. A second message is received from the secondary base station, after transmitting the first message. A third message is transmitted to the secondary base station, after receiving the second message. The first message includes a quality of service (QoS) flow identifier (ID) and available data radio bearer (DRB) IDs. The second message includes the QoS flow ID and a DRB ID corresponding to the QoS flow ID. The third message includes tunnel information for the DRB ID including an Internet protocol (IP) address and a tunnel endpoint identifier (TEID).

Various arrangements for performing navigation based on characteristics of a cellular network are provided. A quality of experience (QoE) level required for a wireless service to be performed for a networked device may be determined. A current location and a destination for a vehicle may be determined. A wireless network coverage area map may be accessed that maps network performance characteristics for the cellular network across a geographic region. A navigation route from the current location to the destination based on the wireless network coverage area map and the determined QoE may be determined. The determined navigational route may be output to a navigation system.

A mechanism is disclosed operating a transport network function (TNF) as part of a fifth generation wireless (5G) virtualized control plane. The mechanism includes receiving a request to compute a traffic engineering (TE) path in a 5G transport network for a packet data unit (PDU) session, the request received from a 5G virtualized control plane function via a service based interface (SBI) bus. Network topology information for the 5G transport network is obtained via a northbound interface (Nn). A TE path across the 5G transport network is computed for the PDU session based on the network topology information. A TE path identifier for the TE path computed for the PDU session is returned via the SBI bus.

Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an aspect, an application layer in a user equipment (UE) receives, from an access layer in the UE, a quality of service (QoS) indication comprising a metric that represents a quality of one or more radio bearers used for a vehicular communication with one or more other UEs. The application layer performs a transmission control over the vehicular communication based on the QoS indication.

This application provides a data transmission method. In the method, a first access network device and a second access network device establish a data radio bearer (DRB)-based tunnel and a session-based tunnel. The second access network device sends a Packet Data Convergence Protocol (PDCP) layer data packet to the first access network device via the DRB-based tunnel; and the second access network device sends a Service Data Adaptation Protocol (SDAP) layer data packet to the first access network device via the session-based tunnel.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-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 suggests a method and an operation for configuring a PDCP layer and a service data association protocol (SDAP) layer, thereby facilitating an efficient flow-based QoS process.

A wireless device (12A) receives a sidelink configuration from each of multiple network nodes (20A, 20B) serving the wireless device (12A). The wireless device (12A) selects, from the received sidelink configurations, a sidelink configuration (16A) that is consistent or compatible with a sidelink configuration (16B) of another wireless device (12B) with which the wireless device (12A) is to communicate over a sidelink. The wireless device (12A) in some embodiments transmits, to each of one or more of the network nodes (20A, 20B) serving the wireless device (12A), an indication of the selected sidelink configuration (16A).

A bearer creation system creates dedicated bearers for sessions requested by user equipment devices based on a policy associated with the user equipment device. The bearer creation system detects that a request to initiate a session has been sent by user equipment associated with a policy. The bearer creation system compares the request to initiate the session to information indicated by the policy, and determines whether to create a dedicated bearer for the session based on the comparison. The bearer creation system creates a dedicated bearer for the session based on a determination that a dedicated bearer should be created.

A control plane function node may be used in a Fifth Generation (5G) Non-Standalone (NSA) architecture having Radio Access Network (RAN) level interworking between a Long-Term Evolution (LTE) RAN and a 5G New Radio (NR). The node obtains usage report data which are based on traffic of a user equipment (UE) via primary and secondary Radio Access Technologies (RATs). The node also obtains secondary RAT usage report data which are based on traffic of the UE via the secondary RAT. The node constructs a message which indicates a request for charging based on the usage report data and the secondary RAT usage report data. In constructing the message, the node populates, in association with a corresponding rating group and usage data of the UE, an identifier of a flow or bearer associated with secondary RAT usage, together with the secondary RAT usage report data.

A method for configuring reflective QoS includes: first indication information transmitted from a Service Data Adaptation Protocol (SDAP) transmitting end is received, the first indication information being configured to indicate a Sequence Number (SN) of a Packet Data Convergence Protocol (PDCP) packet corresponding to a first SDAP packet transmitted according to a new configuration of a pre-established Data Radio Bearer (DRB) or an SN of a PDCP packet corresponding to a last SDAP packet transmitted according to an previous configuration of the pre-established DRB; an SN of a PDCP packet corresponding to a received SDAP packet is acquired; and the acquired SN is compared with the SN indicated by the first indication information to determine whether the SDAP packet includes an SDAP header.
