1. A method for establishing an interface between an intelligent network and a packet data network, comprising the steps of:
- activating a communications session in said packet data network;
a node in said packet data network sending a notification signal to a node in said intelligent network, said notification signal identifying said communications session to said intelligent network;
said node in said intelligent network sending a control signal to said node in said packet data network, said control signal including information to limit a duration of said communications session in said packet data network, said control signal further including a maximum value of packet data for transmission;
if said duration of said communications session is limited to a value less than said maximum value of packet data for transmission, said node in said packet data network sending a second signal to said node in said intelligent network, said second signal including information associated with said duration; and
said node in said intelligent network using said duration information to determine a new maximum value of packet data for transmission.

Abstract
A method and system are disclosed for creating an interface between a packet-switched network and an IN, which is based on an interface between an associated circuit-switched network and an IN/CAMEL service. Meanwhile, the CAMEL application can also provide IN services to mobile subscribers while they are roaming in other networks (e.g., international roaming).

8. A system for establishing an interface between an intelligent network and a packet data network, comprising:
-
means for activating a communications session in said packet data network;
a node in said intelligent network; and
a node in said packet data network, said node in said packet data network including means for sending a notification signal to said node in said intelligent network, said notification signal identifying said communications session to said intelligent network, and said node in said intelligent network including means for sending a control signal to said node in said packet data network, said control signal including information to limit a duration of said communications session in said packet data network and a maximum value of packet data for transmission;
wherein said node in said packet data network includes means for sending a session clear signal to said node in said intelligent network if said duration of said communications session is limited to a value less than said maximum value of packet data for transmission, said session clear signal including information associated with said duration, and means for using said duration information to determine a new maximum value of packet data for transmission. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for establishing an interface between an intelligent network and a packet data network, said system comprising:
-
means for activating a communications session in said packet data network;
a node in said intelligent network; and
a node in said packet data network, said note in said packet data network including means for sending a notification signal to said node in said intelligent network, said note in said intelligent network including means for sending a control signal to said node in said packet data network, said control signal including information to limit a duration of said communications session in said packet data network, said node in said packet data network adapted to send a session clear signal to said node in said intelligent network if said communications session terminates before the limit of said duration of said communications session.
