SYSTEM AND METHOD FOR ACHIEVING CALL TRAFFIC WHOLESALE BASED ON SOFT SWITCH

摘要

The invention discloses a system for achieving traffic wholesale based on soft switch, which includes a soft switch and one or more trunk gateways connecting with the soft switch via an IP network, wherein: logical resources of the soft switch include one or more trunk groups, and each trunk group includes a plurality of trunk circuits; each trunk gateway corresponds to one or more trunk groups, and part or all of physical circuits of the trunk gateways establish a corresponding relationship with the trunk circuits of corresponding trunk groups; the soft switch is configured to: allocate the logical resources including the trunk groups and the trunk circuits of the trunk groups to lessees, and set charging and service configurations for the trunk groups allocated to the lessees. The invention also discloses a method and a soft switch device for achieving traffic wholesale based on soft switch. In the case that the soft switch has large capacity, the invention can rapidly achieve segmentation, and can rapidly achieve capacity expansion, reduction or change logically, without needing the modification of physical devices.
