Voice call method for pluggable mobile terminal

Abstract

The invention provides a pluggable mobile terminal voice calling method. The method comprises the following steps: after a wireless communication module is inserted into an external application module, the wireless communication module performs communication rate matching with the external application module; the wireless communication module receives an AT command which initiates a call request and is sent by the external application module, and the initiated call request comprises a called number of a called party; the wireless communication module establishes voice channel connection with a base station by an air interface according to the called number, and receives successful connection instruction information sent by the base station; the wireless communication module returns an AT command controlled and instructed by a service report to the external application module according to the successful connection instruction information, and performs the voice communication with the called party. In the method, after the wireless communication module is spliced with the external application module and the rate matching is performed, the wireless communication module is responsible for establishing the communication connection with a wireless network, providing a voice channel for a user to perform the voice communication and ensuring the normal voice communication functions of the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a voice call method for a pluggable mobile terminal. Background technique [0002] With the rapid development of mobile communication technologies, the technical development of mobile terminals as mobile communication tools has become a key issue in the industry. Among them, the low-power mobile phone (Personal Handy-phone System; hereinafter referred to as: PHS) (also called "PHS" mobile phone) has become a mobile terminal generally selected by users due to its advantages such as low mobile phone transmission power. [0003] Existing PHS terminals generally adopt a chip set solution integrating baseband and radio frequency circuits. It adopts a standard single-board or double-board circuit structure to integrate peripheral circuits, making it an integrated circuit structure set in the same external application module. That is to say, the existing PHS terminals ar...

Problems solved by technology

In the prior art, the wireless communication module and the peripheral circuit of the mobile terminal that realizes the wireless communication service are integrated together to form an "all-in-one machine". When the user needs to replace the mobile terminal, the entire mobile terminal must be replaced together. The part of the wireless communication module that could have been reused was also discarded, resulting in a serious waste of resources

In addition, if other user handheld devices such as Wenquxing need to have a wireless communication function, the wireless communication module must be integrated inside it, which increases the cost and development cycle.

[0004] Existing mobile terminals realize the wireless communication function by setting the wireless communication module and the external application module in a unified manner. The application has limitations, cannot adapt to various application environments, and is inflexible; the wireless communication module with the same function is not fully utilized to cooperate with external applications.
