Home gateway policy controlling device, system and implementing method thereof

A system for implementing policy control for a home gateway, the system comprising:

• a Service Control Function (SCF),
• a Policy Decision Function Entity (PD-FE) at network side,
• a Transport Resource Control Function Entity (TRC-FE),
• a Policy Execute Function Entity (PE-FE),
• and a Customer Premises Network (CPN), and the system further comprising:
• a Co-located PD-FE configured to receive a Quality of Service (QoS) policy decided and sent by the PD-FE at network side, select a home gateway according to the QoS policy, translate the QoS policy to a QoS policy supported by the home gateway according to capability of the home gateway, and to send the QoS policy supported by the home gateway to the home gateway in the CPN;
• wherein, the home gateway in said CPN comprises a Home Policy Execute Function Entity (HPE-FE) for receiving QoS policy issued by said Co-located PD-FE and performing policy control for service traffic according to said QoS policy;
• wherein said Co-located PD-FE and the PD-FE are connected via an Rd interface at network side;
• and said Co-located PD-FE and said home gateway are connected via an Rh interface.

A method for implementing policy control for a home gateway, the method comprising the following steps of:

• a Co-located Policy Decision Function Entity (PD-FE) receiving a Quality of Service (QoS) policy decided and sent by a PD-FE at network side;
• said Co-located PD-FE selecting a home gateway in a Customer Premises Network according to the QoS policy, and translating the QoS policy to a QoS policy supported by the home gateway according to capability of the home gateway;
• and
• said Co-located PD-FE sending said QoS policy supported by the home gateway to said home gateway;
• wherein said home gateway performs policy control for service traffic according to the QoS policy received;
• wherein said Co-located PD-FE and the PD-FE are connected via an Rd interface at network side;
• and said Co-located PD-FE and said home gateway are connected via an Rh interface.
