Abstract

A Mobile Switching Center (MSC) of a CDMA telecommunications wireless network which includes a CDMA mobile station (MS), a CDMA base station (BS), a CDMA HLR, and an Unstructured Supplementary Service Data (USSD) Gateway. The MSC is capable of receiving a MS initiated USSD request from the BS, determining if the subscriber is authorized to use USSD services and if authorized constructing a MAP message containing the USSD Request which is then sent to a USSD Gateway identified by subscriber profile information received during registration. The MSC is also capable of identifying MAP messaging it receives that contains USSD messaging, constructing an IOS message that contains the USSD messaging and sending the IOS message to the BS which in turn sends it to the MS.
