Abstract

A cellular telephone includes a speaker, a microphone and voice channel establishing components for opening a voice channel between the cellular telephone and a source telephone requesting communications with the cellular telephone without opening the speaker and microphone. Thus, voice communications between the cellular telephone and the source telephone are prevented until a predetermined signal from the user of the cellular telephone is received. The cellular telephone also include delayed speaker and microphone connecting components for receiving and processing data from the source telephone without opening the speaker and the microphone. The data may include the identity of the source telephone or a message which may be displayed for the user of the cellular telephone. Based upon the identity of the source telephone, the user of the cellular telephone may selectively ignore or respond to the request for communications, or may route the request to an automated answering device or another telephone.

Description

field of invention [0001] Generally, the present invention relates to cellular wireless communications. Background of the invention [0002] Currently, cellular wireless communication systems are commonly used to provide voice and data communication to a large number of mobile phones or users. Analog cellular systems such as AMPS, TACS, E-TACS and NMT have been successfully extended all over the world. More recently, some digital cellular systems, such as North America's known as IS-54B and Europe's GSM, PDC and DECT cellular systems, have also been introduced. These and other systems are described in Cellular Radio Systems, edited by Balston et al., Artech Press, Norwood, MA, 1993. [0003] A cellular radio communication system generally includes one or more mobile stations or units, commonly referred to as cellular telephones, one or more base stations and a mobile telephone switching office. A typical cellular wireless communication system may include hundreds of base ...
