Congestion notification method, related device, and system
First Claim
1. A network side device, comprising:
- a receiver configured to;
receive a congestion status of a target network area from a radio access network (RAN) congestion awareness function (RCAF) entity, the target network area being a network area involved in an application service provided by a target application server; and
receive a first congestion query request from the target application server, the first congestion query request comprising information about a target area, and the first congestion query request requesting to acquire a congestion status of the target area;
a transmitter coupled to the receiver and configured to;
send the congestion status of the target network area to the target application server; and
send a second congestion query request to the RCAF entity, the second congestion query request comprising an identifier of the target network area, and the second congestion query request requesting to acquire the congestion status of the target network area; and
a processor coupled to the receiver and the transmitter and configured to;
determine, according to the information about the target area, the identifier of the target network area related to the target area; and
determine, according to a mapping relationship between the information about a target geographic area and the identifier of the target network area, the identifier of the target network area corresponding to the information about the target geographic area.

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.

4. An application server, comprising:
-
a transmitter configured to send a congestion query request to a network side device, the congestion query request comprising information about a target area, the congestion query request requesting to acquire a congestion status of the target area, the information about the target area comprising either an identifier of a target network area or information about a target geographic area, and the information about the target geographic area comprising information about an area not divided by an operator and that cannot be identified by the network side device; a receiver coupled to the transmitter and configured to receive a congestion status of the target network area related to the target area from the network side device; and a processor coupled to the transmitter and the receiver and configured to adjust a running status of an application according to the congestion status of the target network area. - View Dependent Claims (5)
