Problems solved by technology

However, information exchange and sharing cannot be realized between fixed telephones and mobile phones, which causes great inconvenience to users
[0006] In addition, most of the existing PDAs use 8-bit low-end CPU (Center Process sing Unit, central processing unit). This CPU does not support nested processing of interrupts and does not have IrDA codec. device is too expensive

Embodiment Construction

[0027] Such as figure 1 As shown, on the one hand, the PDA of the present invention is connected with the phone through the plug-in interface to realize the information exchange between the PDA and the phone, and on the other hand, it is connected with the mobile phone with infrared function through the IrDA interface to realize the information exchange between the PDA and the mobile phone. More importantly: In this way, the PDA is used as an intermediary between the phone and the mobile phone, and information exchange can also be realized. For example, a phone number on a business card on a PDA can be automatically dialed through the PSTN by inserting a phone, or can be automatically dialed from a mobile phone through infrared; a text message on a PDA can be sent from the PSTN by inserting a phone, or Send from the mobile phone through infrared; the business card on the PDA can be transferred to and from the PHONE BOOK of the mobile phone.

Abstract

A PDA which can realize the two-way communication between PDA and stationary telephone through plug-in arrangement using two wires homologue communication mode on one side, and can accomplish the IrDA communication with the cell phone by infrared mode. In addition, for the lower level PDA with 8-bit CPU, the invention provides a soft decoding apparatus for realizing real time infrared communication by means of phase-varying interruption embedding mode.

Description

technical field [0001] The invention relates to a PDA, in particular to a PDA capable of realizing information communication between a fixed telephone and a mobile phone. Background technique [0002] PDA is the abbreviation of Personal Digital Assistant, which literally means "personal digital assistant". Although the functions of PDAs of different grades vary greatly, one of its most basic functions is to manage personal information (such as business card books, itinerary plans, etc.), and the main purpose of business card books is to make calls. How to connect PDAs with communication terminals , to provide greater convenience to users? In the field of mobile phones, the emergence of Smart Phones reflects this demand; but in the field of fixed phones, business phones or smart phones add PDA functions to fixed phones, which partially meets this demand, but it is an inseparable overall, destroying the portability of the PDA. [0003] One of the applicants, Hanwang Technol...
