Mobile communication terminal and its communication time-termination operation method

Abstract

The invention relates to a mobile communication terminal and its communication time-termination operation method, comprising a shell composed of a communication electronic circuit and a charging battery, wherein the communication electronic circuit comprises a communication module, a charging interface connected with an external charger on the shell and the charging interface is electrically connected with the charging battery, characterized in that; the communication electric circuit comprises a charging detection module directly or indirectly connected with the charging battery, a communication control module for controlling the switch-on and switch-off of the communication module and a timer. When the charging detection module detects that the charging interface of the mobile communication terminal and the external charger are at disengaged state or false charging state, the timer is started and when the timing cumulation time of the timer reaches to a preset time, the control module outputs the control signal to switch off the communication module. After the mobile communication terminal is connected with the external charger, the mobile communication terminal is used as fixed-line telephone and when the mobile communication terminal is disengaged from the external charger, the communication time is limited.

Description

Technical field [0001] The invention relates to a mobile communication terminal and a method for the mobile communication terminal to perform a call time-limited operation. Background technique [0002] Nowadays, the tariff of fixed telephones is lower than that of mobile communication terminals, but fixed telephones are larger in size and must be connected to telephone lines before you can make calls, because fixed telephone lines are fixed. Therefore, the fixed telephone is inconvenient to carry, and it cannot be used for portable communication. Existing mobile communication terminals, such as mobile phones, are generally compact, easy to carry, and convenient to make calls, but relatively expensive. [0003] In some cases, if the mobile communication terminal can be used as a fixed telephone and cooperate with mobile operators, the tariff of the mobile communication terminal can be greatly reduced. This requires the mobile communication terminal to be designed as a relatively f...

AI Technical Summary

Problems solved by technology

[0003] In some cases, if the mobile communication terminal can be used as a fixed phone, and cooperate with the mobile operator, the tariff of the mobile communication terminal can be greatly reduced, which requires the design of the mobile communication terminal as a relatively fixed terminal, while the mobile communication The feature that the terminal must be fixed with an external charger when charging can realize the relative fixation of the mobile communication terminal. In this way, although the mobile communication terminal is a fixed phone in a certain sense, it does not lose its portability and portable call characteristics.

And when the mobile communication terminal is no longer used as a fixed phone, it needs to limit its talk time

[0004] In addition, ordinary terminals only need to short-circuit the positive terminal connected to the battery and the input positive terminal of the power management chip, and the terminal is considered to be charging.
