Document Type and Number:
WIPO Patent Application WO/2008/151481
Kind Code:
A1
Abstract:
A method for centralized controlling the service to implement the terminal call
in a IP multimedia core network subsystem (IMS), includes that: ICCF calls the
UE which accessed by the circuit switched (CS) via the session control path and
carries its ICCF address assigned after it receives the terminal call request
initiated by the calling side; the UE initiates the CS call by using the ICCF address
as the called number and establishes the connection between the UE and the ICCF
to implement the establishment of the bear control path; and the terminal call
is implemented by utilizing the bear control path. This invention can establish
the bear control path without the ICCF assigning the roam number, it is a method
which can solve the ICS terminal call effectively.
