VoIP Traffic Control

With the increasingly wide application of broadband networks,
broadband data services are developing rapidly. The popularity of Voice
over IP (VoIP) services brings carriers a large number of subscribers.
However, VoIP services consume bandwidths,
affecting subscribers usage of ordinary voice services and carriers
charging on fixed-line services. Using bandwidth management, the UGW9811 performs traffic control on VoIP services to ensure
normal service usage.

Table 1 lists the typical application scenarios of VoIP traffic control.

Table 1 Typical application scenarios of VoIP traffic control

Typical Application Scenario	Scenario Description	Application Dimension
Global bandwidth management based on the UGW9811	Bandwidth management is performed on the VoIP services on a UGW9811.	UGW9811
VoIP service control and bandwidth management based on the APN	Service control and bandwidth management are performed on VoIP traffic of an APN.	APN/User group
VoIP traffic policing based on the user group	Service control and bandwidth management are performed on VoIP traffic of a group of subscribers with the same attribute (for example, subscribers with the platinum level of QoS).	APN/User group
VoIP service control and bandwidth management based on the subscriber	Service control and bandwidth management are performed on VoIP traffic of individual subscribers.	Subscribers
Bandwidth management based on the service	Bandwidth management is performed based on services that can be identified by the UGW9811. The services include MSN Messenger and Yahoo Messenger voice services.	Service/Service group
VoIP service control and bandwidth management based on the time segment	Different policies are used for service control and bandwidth management on VoIP traffic based on the time segment.	Time segment (busy hour/idle hour)
VoIP service control and bandwidth management based on the traffic direction	Service control and bandwidth management are performed on VoIP traffic based on the traffic direction, using the same or different policies for traffic in the two directions (uplink/downlink).	Traffic direction (uplink/downlink)
VoIP service control and bandwidth management based on the subscribers location	Service control and bandwidth management are performed on VoIP traffic based on the subscribers location as configured in policies.	Location (local area/roaming area/visiting aea/hotspot cell/non-hotspot cell)
VoIP service control and bandwidth management based on the subscribers roaming attribute	Service control and bandwidth management are performed on VoIP traffic based on the roaming attribute as configured in policies.	Roaming attribute (local subscriber/ roaming subscriber/visitor)
VoIP service control and bandwidth management based on multiple dimensions	Service control and bandwidth management are performed on VoIP traffic based on the combination of the roaming attribute, location, radio access technology (RAT), traffic direction, and time segment. Service control and bandwidth management based on one of the preceding dimensions or any combination of the preceding dimensions are applicable to the entire UGW9811, an APN, a user group, or a subscriber.	Combination of dimensions
VoIP service control and bandwidth management policy changes based on the RAT change	After the RAT is changed, if the service control and bandwidth management policies for VoIP traffic change accordingly, the new policies for service control and bandwidth management take effect with both current traffic and subsequent traffic.	RAT (E-UTRAN/UTRAN/GERAN/WLAN/GAN)
VoIP service control and bandwidth management based on accumulated traffic	Different policies are used for service control and bandwidth management on VoIP traffic based on accumulated traffic. NOTE: The PCRF is required for implementing this function.
