This application discloses a communications method and apparatus. The method includes: sending, by a session management network element, first indication information when the session management network element determines, based on first information, to establish a first low-latency service flow for a session; and the first indication information is used to indicate to set the session to an always-on session. According to solutions of this application, when determining, based on the local configuration information, the subscription data, and the QoS parameter, to establish the low-latency service flow, the session management network element flexibly indicates a terminal apparatus to set the session to the always-on session. This avoids a resource waste caused by setting the session to the always-on session all the time, and avoids a transmission latency caused when the session is not set to the always-on session in time, so that resource utilization and transmission efficiency are improved.

The method includes: A terminal triggers a resource scheduling request when the terminal meets a first trigger condition, where the resource scheduling request is used to request an access network device to allocate an uplink resource or a sidelink resource to the terminal; and the first trigger condition includes: A working mode of the terminal or a working mode of a sidelink service of the terminal is switched from a first mode to a second mode, where the first mode is different from the second mode, and the first mode and the second mode each are one of the following modes: a scheduling mode and a scheduling and autonomous joint mode.

In one embodiment, a method comprises causing, by a network controller device, a first access point (AP) device to initiate a reverse sounding operation comprising wirelessly requesting a mobile constrained network device to transmit a null data packet (NDP) at a first transmission interval, wirelessly receiving the NDP at the first transmission interval, and generating a reception report describing reception of the NDP and including beamforming information; causing, by the network controller device, a second AP device to generate a corresponding reception report describing a corresponding wireless detection of the NDP at the first transmission interval; and causing, by the network controller device, the mobile constrained network device to connect to a selected one of the first AP device or the second AP device for an identified data flow based on the respective reception reports from the first and second AP devices.

A fifth-generation core network (5GC) provides 5G radio access network (RAN) services to a user equipment (UE) in a time-sensitive communications (TSC) network (TSN). This includes receiving a protocol data unit (PDU) session establishment request from the UE, the PDU session establishment request including an industrial Internet of Things (IIoT) vertical or application type, identifying a TSN application function (AF) relating to the IIoT vertical or application type, determining quality of service (QoS) parameters for communications between the UE and the 5G RAN based on the identified TSN AF, the QoS parameters including a survival time for the IIoT vertical or application type and establishing a PDU session with the UE when the QoS parameters including the survival time are satisfied.

Provided is a communication control apparatus which can perform efficient delay control for maintaining quality of an end-to-end flow. A communication control apparatus (10) according to the present disclosure includes an acquiring unit (11) acquiring measured delay times that are end-to-end delay times of a plurality of data pieces included in a flow sent through a plurality of sections, a calculating unit (12) calculating a delay adjustment amount required for satisfying target quality by the flow by using the measured delay times and a target end-to-end delay time that the flow should satisfy, and an updating unit (13) apportioning the delay adjustment amount to each of the sections and updating a target delay time specified in each of the sections by using the apportioned delay adjustment amount.

Systems, methods, and apparatus, including computer-readable media, for enhanced network communication using multiple network connections. In some implementations, a networking apparatus concurrently maintains connectivity to a network through each of multiple network transports. The networking apparatus receives one or more packets to be transmitted over the network and classifies the one or more packets to determine a class of service. The networking apparatus selects one of the multiple network transports to transmit the one or more packets based on (i) the class of service for the one or more packets and (ii) measures of expected latency for transmission of the one or more packets over the respective multiple network transports. The networking apparatus transmits the one or more packets using the selected network transport.

Policy node grouping provides efficient network operation by improving the speed and reliability of policy node traffic. Disclosed solutions include: receiving, at a proxy-call session control function (P-CSCF), from a user equipment (UE), a data traffic session request; based on at least the data traffic session request and group policy criteria, selecting a policy node group from among a plurality of policy node groups, the plurality of policy node groups each comprising policy node peers grouped by a service type; based on at least the selected policy node group, determining a selected policy node; based on at least the selected policy node and the data traffic session request, establishing a data traffic session for the UE; and based on at least meeting policy node failover criteria and a failover latency timer, performing an inter-group or intra-group failover according to the group policy criteria.

Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: receiving information related to the allocation of a first resource from a base station; transmitting sidelink information to a second device through the first resource on the basis of the information related to the allocation of the first resource; and transmitting the sidelink information to the second device through a second resource on the basis of a preset condition.

The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as long term evolution (LTE). A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) is provided. The method includes the steps of generating an RIC control message, and transmitting the RIC control message to an E2 node, wherein the RIC control message includes an information element (IE) for indicating a radio resource control (RRC) message type.

A data packet transmission method—that includes: obtaining, by a terminal, N application programs that are running; and if the N application programs include an application program including a low-latency service; determining whether an unlicensed frequency band is in a congestion state; and instructing a network device to schedule a data packet of the terminal to a licensed frequency band for transmission when the unlicensed frequency band is in a congestion state. When determining that the N running application programs include the application program including the low-latency service, the terminal may instruct the network device to schedule the data packet of the terminal to the licensed frequency band for transmission, so as to transmit a data packet of the low-latency service by using the licensed frequency band. Resources in the licensed frequency band are centrally scheduled by the network device, instead of being used through contention.
