Abstract: A Short Message Service (SMS) communication network is interfaced with an Intelligent Network. In response to an indication from a mobile subscriber to transmit unstructured data towards a particular B-number, a serving mobile switching center/visitor location register (MSC/VLR) determines whether the calling party subscriber or called party subscriber is associated with an IN service. In response to an affirmative determination, instead of transmitting the received unstructured data directly to a Short Message Service-Center (SMS-C), the serving MSC/VLR routes an Integrated Service Digital Network User Part (ISUP) signal encapsulating the unstructured data to the associated Intelligent Network. An associated Service Switching Point (SCP) and Service Control Point (SSP) then provide the desired IN service to the received unstructured data.
