Congestion Notification Method, Related Device, and System
First Claim
1. A congestion notification system, comprising:
- an application server configured to;
send a first congestion query request, wherein the first congestion query request comprises information about a target area;
receive a congestion status of a target network area related to the target area, wherein the target network area is involved in an application service provided by the application server; and
adjust a running status of an application according to the congestion status of the target area;
a service capability exposure function entity configured to;
receive the first congestion query request from the application server;
determine, according to the information about the target area, an identifier of the target network area;
send a second congestion query request, wherein the second congestion query request comprises the identifier of the target network area;
receive the congestion status of the target network area; and
send the congestion status of the target network area to the application server; and
a congestion awareness function entity configured to;
receive the second congestion query request from the service capability exposure function entity;
acquire the congestion status of the target network area; and
send the congestion status of the target network area to the service capability exposure function entity.

Abstract
A congestion notification method, a related device, and a system, where the method includes receiving, by a network side device, a congestion status of a target network area sent by a radio access network (RAN) congestion awareness function (RCAF) entity, where the target network area is a network area involved in an application service provided by a target application server; and sending, by the network side device, the congestion status of the target network area to the target application server. Hence, an application server may able to learn in time when congestion occurs, and adjust, according to the congestion situation, a related service in an area corresponding to the congestion situation.

5. A congestion notification method, comprising:
-
receiving, by a service capability exposure function entity, a first congestion query request from an application server, wherein the first congestion query request comprises information about a target area, and wherein the first congestion query request is to request a congestion status of the target area; determining, by the service capability exposure function entity according to the information about the target area, an identifier that is of a target network area related to the target area, wherein the target network area is involved in an application service provided by the application server; sending, by the service capability exposure function entity, a second congestion query request to a congestion awareness function entity, wherein the second congestion query request comprises the identifier of the target network area, and wherein the second congestion query request is to request a congestion status of the target network area; receiving, by the congestion awareness function entity, the second congestion query request from the service capability exposure function entity; acquiring, by the congestion awareness function entity, the congestion status of the target network area; sending, by the congestion awareness function entity, the congestion status of the target network area to the service capability exposure function entity; receiving, by the service capability exposure function entity, the congestion status of the target network area from the congestion awareness function entity; and sending, by the service capability exposure function entity, the congestion status of the target network area to the application server. - View Dependent Claims (6, 7, 8, 9)
