METHOD FOR PROCESSING CALL IN DUAL WIRELESS TERMINAL USING INTELLIGENT NETWORK

摘要

PURPOSE: A method for processing a call in a dual wireless terminal using an intelligent network is provided to automatically sense a position of the dual wireless terminal and to register a receiving number of a single number service with a wired phone number or a mobile phone number. CONSTITUTION: A wireless phone access device(2) transmits a Port-In position registration request message to a wired phone network(S1). A terminal exchange(6) relays the request message to a service performing exchange(7) according to number translation information(S2). The service performing exchange(7) checks over whether PSTN signal information satisfies intelligent network trigger conditions(S3). If so, the service performing exchange(7) forms an INAP(Intelligent Network Application Protocol) format(S4). The service performing exchange(7) transmits an initial sensing point message to a service control system(S5). The service control system(8) receives the message and extracts a service ID number or a wired or a mobile phone number(S6). The wired or the mobile phone number is registered in service subscriber profile information(S7). The service control system(8) transmits a call cancellation message to the service performing exchange(7). The service performing exchange(7) informs the wireless phone access device(2) of registration completion.
