Problems solved by technology

The effect of using a fixed delay timer to control the load of the NOTIFY message is not ideal: when the load of the presence server is low, it will cause unnecessary impact on user experience; when the load is high, this method cannot be completely limited The total load generated by the presence server on the network

example 1

[0110] OC: Rsp

[0111] ; Oc=500

[0112] ;Oc_type=1

[0113] ;Oc_vaiidity=60000

[0114] ;Oc_tag=AH8TS90JK6

[0115] The OC response header of the load report indicates that the load type of the external network entity is the notification NOTIFY message admission rate, the specific value is 500 messages per second, and the validity period is 60000 milliseconds.

example 2

[0117] OC: Rsp

[0118] ;Oc=0.80

[0119] ;Oc_type=2

[0120] ;Oc_validity=60000

[0121] ;Oc_tag=AH8TS90JK6

[0122] The OC response header of the load report indicates that the load type of the external network entity is the CPU occupancy rate of the external network entity, the specific value is 80%, and the validity period is 60000 milliseconds.

example 3

[0124] OC: Rsp

[0125] ;Oc=0.85

[0126] ; Oc_type=3

[0127] ;Oc_validity=60000

[0128] ;Oc_tag=AH8TS90JK6

[0129] The OC response header of this load report indicates that the load type of the external network entity is the space occupancy rate of the NOTIFY message buffer notified by the external network entity, the specific value is 85%, and the validity period is 60000 milliseconds.

[0130] The specific method for the flow rate generating sub-module in step (3) of the method to calculate the flow control parameters of each flow control sub-module includes the following steps:

[0131] (31) The flow rate generation sub-module processes the load information of the external network entity according to the obtained load information of the external network entity. The specific method is: if the load type oc_type is to notify the NOTIFY message admission rate, no processing is performed;

[0132] If the payload type oc_type is the CPU occupancy rate of the external network entity, the C...

Abstract

The invention discloses a system and a method for controlling the network load of a presence service. The system comprises an Internet protocol (IP) multimedia subsystem network (IMS), a presence server and the like. The presence server consists of a user and service management module, a user and service data storage module, a PUBLISH message distribution module, a load control module, a NOTIFY message transmission module, a load monitoring module and the like, wherein the load control module comprises a state updating caching sub-module, a traffic control sub-module, a traffic rate generation sub-module and the like. The invention also provides the method for controlling the network load of the presence service based on the system. Based on the load measurement of an external network entity, traffic control is performed on PUBLISH messages of users according to priorities, thereby realizing effective control over NOTIFY messages of the presence service and finally ensuring the normalrunning of a service network. The system and the method provided by the invention are simple, convenient and practicable, and the service using satisfaction degree of the users can be effectively increased.

Description

Technical field [0001] The invention relates to a system and method for controlling the network load of a presence service, belonging to the technical field of telecommunications, in particular to the technical field of IP multimedia sub-network IMS. Background technique [0002] One of the main features of presence services is the "one-to-many message notification mode." When the user status changes, the presence server needs to send the changed status information to all online subscribers. In practical applications, a user often has many online subscribers. When the number of users is large, the presence server will generate a large load on the network. Research shows that in the IMS network, the presence service related load accounts for 50% of the total load of the service call session control function S-CSCF in the IP multimedia subsystem network IMS. The analysis of presence service volume distribution shows that most of the load of presence service is caused by the notif...
