Abstract
An information transmission method and a network device are provided. The method includes: obtaining a quality of service QoS parameter sent by a PCF entity, where the quality of service QoS parameter includes a QoS identifier; a packet delivery latency budget over an infrastructure network corresponding to the QoS identifier is greater than or equal to a real packet delivery latency over the infrastructure network, and the real packet delivery latency over the infrastructure network is an actual data transmission latency between a base station and a user plane anchor UPF.
Claims17
An information transmission method, applied to a session management function (SMF) entity, comprising:
- obtaining, by the SMF entity, a quality of service (QOS) parameter sent by a policy control function (PCF) entity, wherein the QoS parameter comprises a QoS identifier;
- wherein a packet delivery latency budget over an infrastructure network corresponding to the QoS identifier is greater than or equal to a real packet delivery latency over the infrastructure network, and the real packet delivery latency over the infrastructure network is an real data transmission latency between a base station and a user plane function (UPF);
- wherein before the obtaining the QoS parameter sent by the PCF entity, the information transmission method further comprises:
- sending, to the PCF entity, information about the real packet delivery latency over the infrastructure network between the base station and the UPF, after selecting the UPF for a packet data unit (PDU) session.
An information transmission method, applied to a policy control function (PCF) entity, comprising:
- sending, by the PCF entity, a quality of service (QOS) parameter to a session management function (SMF) entity, wherein the QoS parameter comprises a QoS identifier;
- wherein a packet delivery latency budget over an infrastructure network corresponding to the QoS identifier is greater than or equal to a real packet delivery latency over the infrastructure network, and the real packet delivery latency over the infrastructure network is an real data transmission latency between a base station and a user plane function (UPF);
- wherein before the sending the QoS parameter to the SMF entity, the information transmission method further comprises:
- obtaining information about the real packet delivery latency over the infrastructure network between the base station and the UPF, wherein the information about the real packet delivery latency over the infrastructure network is sent by the SMF entity.
An information transmission method, applied to a base station, comprising:
- obtaining, by the base station, QoS control information of a QoS flow sent by a session management function (SMF) entity;
- and
- determining a packet delivery latency over an air interface according to the QoS control information, and performing resource scheduling according to the packet delivery latency over the air interface;
- wherein the QoS control information comprises a QoS identifier, a packet delivery latency budget corresponding to the QoS identifier, and a packet delivery latency budget over an infrastructure network corresponding to the QoS identifier;
- or, the QoS control information comprises a QoS identifier and the packet delivery latency over the air interface corresponding to the QoS identifier.
