Description
Time-sensitive communication configuration method and communication system
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application is based on the application with CN application number 202311048901.3 and application date August 18, 2023, and claims its priority. The disclosed content of the CN application is hereby introduced as a whole into this application. Technical Field
[0003] The present application relates to the field of wireless communication technology, and in particular to a time-sensitive communication configuration method and a communication system. Background Art
[0004] Time-Sensitive Communication (TSC) is a communication method that requires very high latency and timeliness, and is often used in application scenarios that require real-time, timely response and processing. To meet the needs of time-sensitive communication, the core network can send time-sensitive service-related characteristics (such as flow direction, burst arrival time, maximum burst size, periodicity, lifetime, etc.) to the base station through Time-Sensitive Communication Assistance Information (TSCAI). The base station can reserve communication resources for related deterministic services through configuration authorization, semi-static scheduling, dynamic authorization, etc. When time-sensitive data packets arrive, they no longer need to be scheduled, thereby reducing waiting time and meeting latency requirements.
[0005] To provide different QoS for different services, the Radio Access Network (RAN) provides QoS (Quality of Service). QoS management is a control mechanism used by wireless networks to meet different service quality requirements. The 5G protocol uses the 5QI (5G QoS Identifier) to identify different service priorities. According to standard TS23.501, the 5G QoS model is primarily based on QoS flows. It supports two types of QoS flows: guaranteed bit rate (GBR) QoS flows and non-GBR QoS flows.
[0006] In the current standard, base stations can only obtain time-sensitive information, period, burst arrival time, lifetime and other parameters with guaranteed bit rate from the core network through time-sensitive communication auxiliary information. Considering that services such as extended reality need to support non-guaranteed bit rate QoS flows, and need to consider characteristics such as service jitter and non-integer service periods, the existing 3GPP (3rd Generation Partnership Project) 5G protocol can no longer meet application requirements, and base stations cannot provide more reasonable resource scheduling to achieve time-sensitive communication.
[0007] To address the above-mentioned problems, no effective solutions have been proposed so far.

[0101] During the PDU session resource modification process, the base station may modify an established PDU session, thereby modifying the corresponding time-sensitive communication service configuration.
[0102] FIG4 is a schematic diagram of communication between a base station and a core network in a PDU session resource modification scenario, specifically including the following steps:
[0103] S1, the AMF network element in the core network sends a PDU session resource modification request message to the base station, which also includes at least one of the following: first configuration information related to the time-sensitive communication service, and second configuration information related to the quality of service QoS flow;
[0104] S2, the base station feeds back the PDU session resource modification response message to the AMF network element in the core network.
[0105] It should be noted that the first configuration information and the second configuration information in the PDU session resource modification scenario are the same as the first configuration information and the second configuration information in the PDU session resource establishment scenario, and the content of the PDU session resource modification response message and the PDU session resource establishment response message are also the same, so they will not be elaborated here.
[0106] In some embodiments, the base station can also receive first auxiliary information sent by the terminal, wherein the first auxiliary information includes at least one of the following: uplink PDU set delay overhead, uplink PDU set error rate, uplink PDU set comprehensive processing indication, uplink PDU set importance indication, uplink service cycle, uplink service jitter, and uplink PDU set dynamic parameters.

[0109] Considering that wireless link layer transmission is mainly based on individual PDUs rather than PDU sets, the base station needs to convert the PDU set related parameters in the configuration information obtained from the core network and the auxiliary information obtained from the terminal into PDU related parameters.
[0110] In some embodiments, the base station may first receive the fourth configuration information sent by the core network, wherein the fourth configuration information includes at least one of the following: a PDU set encoding and decoding method for deriving the data packet error rate from the PDU set error rate, and a downlink PDU set dynamic parameter.

[0114] S1, the base station sends radio resource control (RRC) signaling reconfiguration information (RRC Reconfiguration) to the terminal;
[0115] S2. The terminal feeds back first auxiliary information to the base station.

[0122] Finally, the terminal may determine the priority level for performing a receiving or discarding operation on each PDU in the downlink service according to the downlink configuration information, and receive or discard each PDU according to the priority level.
[0123] For example, for downlink services, the terminal prioritizes receiving and / or discarding the corresponding PDU in the event of link congestion based on parameters such as the downlink PDU aggregate delay overhead, downlink PDU aggregate importance indication, downlink service data packet error rate, and data packet delay budget in the downlink link configuration information.
[0124] In some embodiments, the terminal may determine the priority level of performing an uplink operation on each PDU in the uplink service according to the uplink configuration information, and send each PDU according to the priority level.
[0125] For example, for uplink services, the terminal may give priority to sending relevant uplink data packets based on parameters such as pre-configured authorized resources, uplink service data packet error rate, and uplink PDU aggregate delay overhead in the uplink configuration information.
[0126] In the present application scheme, the base station can obtain both time-sensitive communication related parameters with guaranteed bit rate and time-sensitive communication related parameters without guaranteed bit rate from the core network. At the same time, the base station can also obtain uplink time-sensitive communication related parameters from the terminal.

[0137] In some embodiments, the terminal may determine the priority level for performing a receiving or discarding operation on each PDU in the downlink service according to the downlink configuration information, and receive or discard each PDU according to the priority level.
