Abstract
In a packet loss rate detection method, a session management network element determines that link status detection needs to be performed on a link on which a service flow is located; and the session management network element sends a link status detection indication to a first device and/or a second device, where the link status detection indication is for enabling a link status detection function, and the link status detection function includes a packet loss rate detection function.
Claims20
A method implemented by a session management network element and comprising:
- making a determination that link status detection per quality of service (QoS) flow is applied for a multi-access protocol data unit (PDU) session, wherein the multi-access PDU session supports a service that simultaneously uses a 3rd Generation Partnership Project (3GPP) access and a non-3GPP access;
- and
- sending, to a first device and in response to the determination, a QoS flow identifier (QFI), a first port number associated with the 3GPP access, and a second port number associated with the non-3GPP access,
- wherein the QFI indicates a QoS flow on which the link status detection is performed,
- wherein the first port number is for the link status detection on the 3GPP access, and
- wherein the second port number is for the link status detection on the non-3GPP access.
3 more elements
A session management network element comprising:
- a memory configured to store computer instructions;
- and
- one or more processors coupled to the memory and configured to execute the computer instructions to cause the session management network element to:
- make a determination that link status detection per quality of service (QoS) flow is applied for a multi-access protocol data unit (PDU) session, wherein the multi-access PDU session supports a service that simultaneously uses a 3rd Generation Partnership Project (3GPP) access and a non-3GPP access;
- and
- send, to a first device and in response to the determination, a QoS flow identifier (QFI), a first port number associated with the 3GPP access, and a second port number associated with the non-3GPP access,
- wherein the QFI indicates a QoS flow on which the link status detection is performed,
- wherein the first port number is for the link status detection on the 3GPP access, and
- wherein the second port number is for the link status detection on the non-3GPP access.
