Patent ID: 7881317

Claim:
A method for implementing control by a border/packet gateway control system, comprising: setting a control policy in the border/packet gateway control system for controlling bearer resources; obtaining network resource information, generating a service decision related to IP network interconnecting according to the control policy and the network resource information, wherein the control policy comprises operation demands from an operator; performing IP network interconnecting according to the service decision; wherein the border/packet gateway control system comprises a Border Gateway Control Function Entity/Packet Gateway Control Function Entity (BGCFE/PGCFE), a Policy Decision Function Entity (PDFE), a Transport Resource Control Function Entity (TRCFE), and a Border Gateway Function Entity/Packet Gateway Function Entity (BGFE/PGFE); said obtaining network resource information and generating the service decision according to the control policy and the network resource information comprises: sending, by the BGCFE/PGCFE, a resource request of the IP network interconnecting to the PDFE; requesting, by the PDFE, the TRCFE to allocate appropriate network resources; feeding back, by the TRCFE, the network resource information to the PDFE; generating, by the PDFE, the service decision related to IP network interconnecting services according to the control policy and the network resource information; said sending the resource request of the IP network interconnecting to the PDFE comprises: sending, by the BGCFE/PGCFE, service control information related to IP network interconnecting to the PDFE; and said performing IP network interconnecting according to the service decision comprises: adjusting, by the PDFE, the service control information according to the service decision; choosing, by the PDFE, a BGFE/PGFE and sending the adjusted service control information to the BGFE/PGFE; performing, by the BGFE/PGFE, IP network interconnecting according to the adjusted service control information.
