Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention recovers the device of mobile terminal download path, such as figure 2 As shown, the device includes: a main chip 21 of a mobile terminal, a download interface 22, a capacitor 23, and a switch circuit 24; wherein,

[0018] One end of the capacitor 23 is connected to the pin of the main chip 21 of the mobile terminal, and the other end is connected to the switch circuit 24;

[0019] The switch circuit 24 is connected in series between the main chip 21 and the download interface 22 of the mobile terminal.

[0020] Wherein, the discharge time of the capacitor 23 is longer than the time required for downloading the resume command, and far shorter than the time required for downloading the updated software, thus preventing illegal personnel from illegally downloading within the discharge time of the capacitor...

Abstract

The present invention discloses a device for restoring the download path of a mobile terminal, and the device includes a capacitor(23) and a switch circuit(24), wherein one end of the capacitor(23) is connected with a pin of the main chip(21) of the mobile terminal, and the other end is connected with the switch circuit(24); and the switch circuit(24) is serially connected between the main chip(24) of the mobile terminal and a download interface(22). The application of the present invention can realize the legal download purpose of legally downloading update software, thereby improving user experience, effectively preventing a hacker from illegally reading data from and downloading data to the mobile terminal, and better achieving the purpose of network locking.

Description

technical field [0001] The invention relates to security technology in the field of communication, in particular to a device for restoring the download path of a mobile terminal. Background technique [0002] At present, the operation mode of global mobile operators is: provide users with mobile terminals such as mobile phones free of charge, users must abide by the agreement, and must use the operator's network within the specified time. In order to prevent the users of operator A from illegally entering the network of operator B within the specified time, the mobile terminal provided by the manufacturer to the operator must be processed by the network locking technology, that is, a mobile terminal can only use a fixed operator network provided. [0003] In the initial network lock technology, the operator adopted the machine-card integrated mode, such as: China Unicom uses the Code Division Multiple Access (CDMA, Code Division Multiple Access) operation mode, for the mobi...
