## Abstract

This application provides methods, devices, and systems. In an example method performed by a session management network element, the session management network element receives a first policy and charging control (PCC) rule from a policy control network element, wherein the first PCC rule comprises indication information, and the indication information indicates that a service corresponding to the first PCC rule is a time sensitive service. The session management network element binds the first PCC rule to a quality of service (QoS) flow, wherein no other PCC rule is bound to the QoS flow.

## Claims

### Claim 1

A charging rule binding method, wherein the method comprises:
determining, by a policy control network element, a first policy and charging control (PCC) rule corresponding to a time sensitive service, wherein the first PCC rule needs to be bound to a quality of service (QoS) flow, and no other PCC rule is bound to the QoS flow; and
sending, by the policy control network element, the first PCC rule to a session management network element, wherein the first PCC rule comprises indication information, wherein the indication information indicates that the first PCC rule corresponds to the time sensitive service;
receiving, by the session management network element, the first PCC rule from the policy control network element; and
binding, by the session management network element, the first PCC rule to the QoS flow.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
determining, by the session management network element based on the indication information, that the first PCC rule needs to be bound to the QoS flow.

### Claim 3 (depends on 1)

The method according to claim 1, further comprising:
creating, by the session management network element, the QoS flow according to the first PCC rule.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the indication information further indicates one or more of:
that the first PCC rule is a multi-level PCC rule; or
that the time sensitive service corresponding to the first PCC rule requires QoS monitoring.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising:
determining, by the session management network element based on a flag bit in the session management network element, that a second PCC rule cannot be bound to the QoS flow.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising:
sending, by the session management network element to a radio access network device, time sensitive communication assistance information (TSCAI) of the time sensitive service corresponding to the QoS flow.

### Claim 7 (depends on 1)

The method according to claim 1, further comprising:
including, by the policy control network element, the indication information in the first PCC rule.

### Claim 8 (depends on 1)

The method according to claim 1, wherein the indication information further indicates one or more of:
that the QoS flow corresponding to the first PCC rule is not bound to any other PCC rule;
that the first PCC rule is a multi-level PCC rule; or
that the time sensitive service corresponding to the first PCC rule requires QoS detection.

### Claim 9

A system for charging rule binding, comprising:
a policy control network element, configured to:
determine a first policy and charging control (PCC) rule corresponding to a time sensitive service, wherein the first PCC rule needs to be bound to a quality of service (QOS) flow, and no other PCC rule is bound to the QoS flow; and
send the first PCC rule, wherein the first PCC rule comprises indication information, wherein the indication information indicates that the first PCC rule corresponds to the time sensitive service; and
a session management network element, configured to:
receive the first PCC rule from the policy control network element; and
bind the first PCC rule to the QoS flow.

### Claim 10 (depends on 9)

The system according to claim 9, wherein the session management network element is further configured to determine, based on the indication information, that the first PCC rule needs to be bound to the QoS flow.

### Claim 11 (depends on 9)

The system according to claim 9, wherein the session management network element is further configured to create the QoS flow according to the first PCC rule.

### Claim 12 (depends on 9)

The system according to claim 9, wherein the indication information further indicates one or more of:
that the first PCC rule is a multi-level PCC rule; or
that the time sensitive service corresponding to the first PCC rule requires QoS monitoring.

### Claim 13 (depends on 9)

The system according to claim 9, the session management network element is further configured to determine, based on a flag bit in the session management network element, that a second PCC rule cannot be bound to the QoS flow.

### Claim 14 (depends on 9)

The system according to claim 9, the session management network element is further configured to send to a radio access network device, time sensitive communication assistance information (TSCAI) of the time sensitive service corresponding to the QoS flow.

### Claim 15 (depends on 9)

The system according to claim 9, the policy control network element is further configured to include the indication information in the first PCC rule.

### Claim 16 (depends on 9)

The system according to claim 9, wherein the indication information further indicates one or more of:
that the QoS flow corresponding to the first PCC rule is not bound to any other PCC rule;
that the first PCC rule is a multi-level PCC rule; or
that the time sensitive service corresponding to the first PCC rule requires QoS detection.
