Mobile broadband (MBB) services have been experiencing explosive growth. With
this background, the operating modes of the traditional packet switched
(PS) networks face various challenges, and measures
must be taken to implement refined operation.

• The ratio of traffic volume to revenue varies according to
  service types. For example, point to point (P2P) services such as
  BitTorrent (BT) services use a large amount of network resources, but
  bring only a moderate amount of revenue for carriers.
  Therefore, to increase their revenue, carriers must implement
  service-specific policy and charging control (PCC).
• A large
  number of service providers (SPs) or content providers (CPs) are making
  excessive amount of money by providing services on the broadband
  networks, but carriers who own these broadband networks only obtain
  limited rental from the SPs or
  CPs. To make the most out of their investment on broadband networks and
  improve their profitability, carriers must implement service-specific
  PCC.
• A large number of low-ARPU subscribers subscribe to monthly
  packages with no traffic limit. These subscribers use a large amount of
  network resources but do not increase carriers revenue. Therefore, to
  efficiently allocate network resources
  and increase carriers revenue, PCC needs to be implemented for these
  subscribers when the network resource usage reaches a specified
  threshold.
