Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In order to meet the deterministic service guarantee of the wireless dynamic air interface vertical industry, the embodiment of the invention provides a wireless service transmission control method, which generates wireless configuration information according to the wireless requirement to be guaranteed and the service characteristic information acquired in real time so as to realize the deterministic service guarantee of the wireless access network to the service.

In general technologies, user experience is mainly guaranteed through a core network QoS mechanism and a Service Level Agreement (SLA) of a network slice. The Radio Access (NR) protocol stack maps IP flows with the same Qos requirement to the same Qos Flow through a Session Management Function (SMF), and then provides the IP flows with the RAN through an Access and Mobility Management Function (AMF) entity. And the base station gNB maps the QoS Flow to the DRB, so that a Radio Access Network (RAN) side adapts to the QoS requirement. Thus, two-level mapping is formed, so that the RAN side has a certain degree of freedom, for example, the gNB can convert M QoS flows into N DRBs according to a certain policy and a certain policy.

In addition, currently, 5G executes QoS processing based on the granularity of a flow, uses QoS Flow Identifiers (QFI) to identify different QoS flows, and a network side executes forwarding of packets based on QFI, where user plane Data with the same QFI in a Protocol Data Unit (PDU) session will obtain the same forwarding processing (such as the same scheduling, the same admission threshold, and the like). No bearer exists between the 5GC and the RAN, when a new QoS requirement exists, only a radio bearer needs to be established, for each PDU session, a single tunnel is formed between the 5GC and the RAN, and the RAN side manages a Data Radio Bearer (DRB) and mapping from QoS Flow to the DRB. The implementation of the 5G QoS guarantee is performed through the operation of the QoS Flow, which may be configured in advance or maintained through the PDU session establishment/modification procedure. However, by adopting the general technical manner, a QoS pre-configuration mechanism is used to provide customized guarantee for a user, and since the granularity of QoS for service characteristic definition is coarse, service requirements cannot be described finely, so that it is difficult to guarantee that service requirements of a vertical industry local scene with deterministic requirements on time delay, rate and reliability are met.

In order to solve the above technical problem, embodiments of the present invention provide a wireless service transmission control method, so as to implement a wireless service guarantee based on service requirements and service characteristics, and implement an intelligent guarantee for a wireless access network on services.
