Abstract

The invention is applicable to the communication technical field, and provides a coexisting device of mobile terminal peripheral equipment. The device comprises a central processing unit,, the mobile terminal peripheral equipment comprises a safety data (SD) card and a safety data input/output (SDIO) device, and further comprises a change-over switch which is connected with the mobile terminal peripheral equipment and the central processing unit and is used for controlling establishment of connection communication between the central processing unit and the mobile terminal peripheral equipment according to the type of an interrupt request; and a second interrupt request sender which is connected with the central processing unit and the safety data input/output device and is used for sending a second interrupt request to the central processing unit when the first interrupt request is lost. In the coexisting device, the change-over switch controls the connection communication between the central processing unit and the mobile terminal peripheral equipment according to the interrupt request, and sends the second interrupt request by the second interrupt request sender when the first interrupt request is lost, thus solving the loss problem of the first interrupt request of the SDIO device, and realizing the coexistence of the SD card and the peripheral equipment such as the SDIO device.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a mobile terminal peripheral device coexistence device, a switching method and a switching system. Background technique [0002] With the continuous development of communication technologies, peripheral devices such as Secure Digital Card (Secure Digital Card, SD) and Secure Digital Input / Output (Secure Digital Input / Output, SDIO) devices are continuously integrated on mobile terminals. SD card adopts parallel transmission mode and has high data transmission rate; SDIO devices include GPS, Bluetooth, WiFi modules and other devices using SDIO protocol. However, the mobile terminal has only one SD hardware interface, which cannot be used in coexistence, and cannot transfer data acquired by the SDIO device to the SD card. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a mobile terminal peripheral device c...
