发明名称 System and method for improved mobile phone functionality
摘要 A system and method for providing a hold operation from a mobile telephone. When a call is received and the mobile telephone user cannot readily answer the phone, he presses a "hold" key on the mobile telephone. The hold key plays a message to the caller informing the caller that the receiver intends to answer the call momentarily. In this manner, calls received in places where mobile telephone calls are discouraged or prohibited can be placed on hold until the receiver has moved to a location where he can answer the call. For example, in a theater incoming calls can be held so the user can move to a hallway where he can answer the call and talk to the caller. Wireless technology (Bluetooth) is used to automatically hold calls when the mobile telephone receives a command from a server that installed in the theater or other public place.
