Embodiment Construction
[0037] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the technical solutions of the present invention. For the sake of clarity and simplicity, detailed descriptions of known functions and constructions in the devices described herein will be omitted when it may obscure the subject matter of the present invention.
[0038] first combined with figure 1 The device described in the embodiment of the present invention will be described in detail.
[0039] The device described in the embodiment of the present invention is set in the terminal. When the terminal performs PPP data services in a dormant state, if the user unplugs the USB data cable or restarts the computer, the device can detect the abnormality and perform PPP data service link disconnecti...

The invention discloses a device for realizing point to point protocol data service disconnection. The device is arranged in a terminal and comprises a detection module, a processing module and a disconnection module, wherein the detection module is used for detecting a state of a PC (namely personal computer) which is connected to the terminal when the terminal performs PPP data service in a hibernation state, and notifying the processing module when the PC is determined in an unavailable state at present; the processing module is used for establishing a wireless physical link first and then sending a disconnection request to a network side when the processing module is informed of the unavailable state of the PC, and triggering the disconnection module when receives a disconnection request response from a network side; and the disconnection module is used for disconnecting the PPP data service link. According to the device, if a user unplugs a USB data wire or restarts a computer when the device performs the PPP data service in the hibernation state, the abnormity can be detected and the PPP data service disconnection is performed so that the problem of network resource waste is avoided, and also the data charging is more precise.
Description
technical field [0001] The invention relates to the technical field of databases, in particular to a device and method for realizing point-to-point protocol data service link disconnection. Background technique [0002] In the PPP (Point to Point Protocol, point-to-point protocol) data service of prior art CDMA, the user uses the USB data line to connect the PC (personal computer) and the CDMA terminal, if the user disconnects the PC side and the network side by clicking the link icon on the PC The PC will send a terminate request (termination request) message to the network side through the CDMA terminal. After receiving the request message, the network side will send a reply terminate ack (termination response) message, thereby realizing the PPP data service. Broken chain. [0003] However, if the user restarts the PC or unplugs the USB data cable while the user is performing a data service connection in a dormant state, in this case, the PC cannot send a PPP link disconn...
