SYSTEM AND METHOD FOR PROVIDING DEVICE-AWARE SERVICES IN AN INTEGRATED TELECOMMUNICATIONS NETWORK

摘要

A system and method of device-aware service provisioning in a hybrid/integrated telecommunications network (200) having a packet-switched network portion (PSN) and heterogeneous circuit-switched network (CSN) portions. A user profile (402) is provided which partitions a service in thr ee dimensions: a user-specific service part (304), a device-specific service pa rt (306), and a combination part (308) which specifies service conditions when an end-user uses a particular device or terminal. A common IP telephony Value- Added Services infrastructure is included wherein device-aware service triggers (208) are provided for triggering appropriate service partitions of the user profile. Upon encountering a device-aware service trigger in a call control process, a service switching node (204) queries the user profile (40 2) and determines the service conditions associated with the particular device- specific service part to be invoked. Responsive to determining the service conditions, the service switching node instructs a service node (206) to execute an appropriate Service Logic Program. Upon receiving a result or an indication thereof from the service node, the service switching node takes a corresponding service action.
