Problems solved by technology

Also, the radiotelephone antenna can be connected to only one circuit board, thus requiring a radio path between the two circuit boards further complicating the structure
Similar issues may arise with regard to battery connections and connections to external devices
It is also difficult to organize a phone book (phone numbers) between the two wireless phone modes
Overall, this approach may require complex inter-board connections and communications, and multiple system clocks may cause interference

Abstract

A multiple mode radiotelephone provides radiotelephone communications using first and second radiotelephone communications modes. The multiple mode radiotelephone includes a first chip set providing radiotelephone communications according to the first radiotelephone communications mode, a second chip set providing radiotelephone communications according to the second radiotelephone communications mode, a user interface, and a glue circuit. The first chip set includes at least one integrated circuit chip, the second chip set includes at least one integrated circuit chip, and the first and second chip sets are distinct. The user interface accepts user input and provides user information. The glue circuit couples the user interface to the first chip set when providing radiotelephone communications according to the first radiotelephone communications mode, and the glue circuit couples the user interface to the second chip set when providing radiotelephone communications according to the second radiotelephone communications mode.

Description

technical field [0001] This invention relates to the field of communications and in particular to radiotelephone communications. Background technique [0002] Many different communication standards are currently used to provide wireless telephony communication services. For example, currently in use are the Global System for Mobile Communications (GSM) standard, the Digital Cellular System 1800 (DCS1800) standard, the Advanced Mobile Phone System (AMPS IS-54) standard, the Digital Advanced Mobile Phone System (DAMPS IS-136) standard, the Direct Sequence Code The Division Multiple Access (DS-CDMA IS-95) standard and Personal Digital Cellular (PDCRCT-STD27) provide cellular radiotelephone communications services. For example, cordless radiotelephone communications are provided using the Cordless Telecommunications 3 (CT2 CAI) standard, the Digital European Cordless Telecommunications (DECT) standard, and the Personal Handyphone System (PHS). Various radiotelephone communicat...
