the SOFTSWITCH control equipment directly.
Existing conventional intelligent services can be implemented through
virtual SSP obtained by interworking of SG and existing SCP.

multimedia services can be implemented through supported application
servers
A WEB Server being added to a network can serve as a service registration
and selection platform of IP subscribers and as a service subscriber
window. An application server in specific applications can provide standard

leased to enterprise group subscribers for providing customized services,
or serve as a VAS platform for network operators.
