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.

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.

Yes you are right.......VoIP service control and bandwidth management policy changes based on the RAT change

Yes you are right we can use different policies  for service control and bandwidth management on VoIP traffic based on accumulated traffic.
