Problems solved by technology

[0004] However, if the QoS flow is only determined according to the QoS requirements according to the above process, the determined QoS flow may cause the air interface to fail to meet the QoS requirements for the QoS flow, resulting in the network being unable to support the transmission of URLLC service data.

Embodiment 1

[0120] For a service data flow of URLLC type, the PCF formulates the PCC rule corresponding to the service data flow according to the service requirement and operator's policy and sends it to the SMF. The PCC rule sent by the PCF to the SMF includes 5QI, ARP and / or GBR information, wherein the 5QI is a standardized or pre-agreed value, for example, a pre-agreed value for each operator. In this way, the SMF can determine the specific transmission delay corresponding to each 5QI and the maximum amount of data MDBV that can be transmitted within a specific time window by the air interface required for this transmission delay according to the value of the 5QI. Alternatively, instead of using the standardized or pre-configured MDBV value, the PCF may also carry a new MDBV value in the PCC rule to cover the standardized or pre-configured MDBV value, so that the SMF determines the MDBV carried by the PCC rule The value is the transmission capacity of the air interface.

Embodiment 2

[0126] The difference from Embodiment 1 is that the PCF defines non-standard 5QIs, and sends the QoS parameters corresponding to each 5QI to the SMF. The QoS parameters corresponding to the 5QI include, for example, a specific transmission delay and the maximum amount of data MDBV that can be transmitted by the air interface within a specific time window required for this transmission delay. The QoS parameters corresponding to each 5QI are sent to the SMF by the PCF when sending the PCC rule, or are combined into the PCC rule and sent to the SMF through a signaling.

[0127] The SMF binds the service data flow corresponding to the received PCC rule to at least the QoS flow, and assigns a flow identifier to each QoS flow, and sends the QFI of one or more established QoS flows and the corresponding packet filtering information to the UE, The QFI and corresponding QoS requirements of one or more established QoS flows, that is, the control information of the QoS flows, are sent to...

Abstract

The invention discloses a service quality control method, equipment and computer storage medium, enabling AN to perform wireless resource scheduling to ensure the service quality of data flow transmission and meet the time delay requirement of URLLC service data transmission. The method includes that the SMF receives policy control and charging PCC rules sent by the PCF, the PCC rules include QoS requirements and GBR requirements for service data flows, and the PCC rules also indicate air interface transmission capabilities; the SMF will The service data flows corresponding to the PCC rules with the same QoS requirements are bound to at least one QoS flow, and the sum of the GBRs of the PCC rules bound to the same QoS flow does not exceed the transmission capacity of the air interface; the SMF sends the control information of at least one QoS flow For the access network AN, the control information is used for at least one QoS flow to perform radio resource scheduling to ensure the quality of service of data flow transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, equipment and computer storage medium for quality of service control. Background technique [0002] See figure 1 , is the network architecture diagram of the next-generation NextGen network system. Based on this network architecture diagram, the process of determining service quality control information is as follows: the policy control function entity (Policy Control Function, PCF) divides the service data flow (service data flow, SDF) level The policy control and charging (Policy Control and Charging, PCC) rules are sent to the session management function entity (Session Management Function, SMF), wherein, the PCC rules include service quality (Quality of Service, QoS) requirements, and the SMF will Different PCC rules are bound, PCC rules with the same QoS requirements are bound to the same QoS flow, and a flow identifier (QoSflow ID, QFI) is assigned to the ...
