APPARATUS AND METHOD FOR SELECTIVELY CONNECTING TO AN INCOMING VOICE CALL RECEIVED DURING WIRELESS DATA COMMUNICATION

摘要

An exchange (100) provides wireless voice and data communication services to the subscribers (A, B). A subscriber (A) is connected to a wireless data communication service provided by data processor (400). An incoming voice call, originated by another subscriber (B) and directed to said subscriber (A) is received at the exchange (100) and processed by a voice call processor (300), inquiring from the subscriber status information processor (430) whether said subscriber (A) is in connection with the wireless data communication service. Responsive to said inquiry the data processor (400) informs subscriber (A) of the incoming voice call by means of a data message directed to the mobile communication terminal of said subscriber (A). If subscriber (A) decides to take the incoming voice call the voice call processor (300) connects the two subscribers (A, B). Prior to connecting the two subscribers (A, B) the current status of the data communication is stored to re-establish wireless data communication service after termination of the incoming voice call.
