Method, device and system capable of connecting mobile terminal to fixed-line telephone network

Abstract

The invention provides a method, a device and a system capable of connecting a mobile terminal to a fixed-line telephone network. The method capable of connecting the mobile terminal to the fixed-line telephone network includes that a connection of a trust expander and a telephone switchboard of the fixed-line telephone network is built, the trust expander scans whether an attachable wireless signal connecting module of the mobile terminal exists through a wireless function module in the inner potion of a trust expander; when the wireless signal connecting module of the mobile terminal is scanned, a connecting relation of the wireless function module in the inner portion of the trust expander and the wireless signal connecting module of the mobile terminal is built; and when the trust expander keeps wireless connection with the mobile terminal, the communication trust between the mobile terminal and the fixed-line telephone switchboard is conducted. The method, the device and the system capable of connecting the mobile terminal to the fixed-line telephone network can fully make advantage of performances and functions of the mobile terminal on the premise of keeping the advantages that the fixed-line telephone terminal is low in radiation and good in call stability, and the performances and functions of the mobile terminal are better than the fixed-line telephone.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for connecting a mobile terminal to a fixed telephone network. Background technique [0002] Due to the use of wired communication technology, fixed telephones have the advantages of zero radiation and good call stability, so they still occupy an important position in modern communication equipment. Fixed telephones still have many inconvenient factors, such as no address book and caller ID function, no mobility, etc. When users use fixed telephones, they need to search and input phone numbers, which is easy to cause inconvenience in searching and dialing errors; secondly, when answering calls, Landline phones can only display the caller number, but cannot provide users with contact information, which can easily lead to confusion in judgment. In addition, landline phones do not have a recording function, making it impossible for users to keep im...

AI Technical Summary

Problems solved by technology

Fixed telephones still have many inconvenient factors, such as no address book and caller ID function, no mobility, etc. When users use fixed telephones, they need to search and input phone numbers, which is easy to cause inconvenience in searching and dialing errors; secondly, when answering calls, Landline phones can only display the caller number and cannot provide users with contact information, which can easily lead to confusion in judgment. In addition, landline phones do not have a recording function, making it impossible for users to keep important conversations after the call is over.

[0003] Mobile terminals such as mobile terminals have the characteristics of being able to communicate wirelessly through the base station and store a large amount of information, which can completely avoid the various problems of the above-mentioned fixed telephones. The frequency of use in daily life is very high, but the signal radiation of mobile terminals is large, Problems such as unstable signals cannot be ignored. It can make up for the shortcomings of fixed-line terminals but cannot have the advantages of fixed-line terminals.
