Embodiment 1

[0045] like figure 2 As shown, the embodiment of the present invention provides a driving device for multi-PDP data communication of mobile broadband equipment, which specifically includes:

[0046] The RIL module 210 is used to receive a function call request message based on data or configuration services from the Android system, and call the PDP management module 220 through the extended multi-PDP support interface;

[0047] The PDP management module 220 is configured to obtain the PDP type of the access device currently supported by the system and corresponding to the function call request, and trigger the PDP control module 230 to process messages based on NDIS or PPP according to the PDP type; After the creation or destruction is successful, update and maintain the PDP resource status table that records the PDP type, PDP status and identification information of the corresponding access device; among them, the PDP type of the access device mainly includes NDIS-based PDP ...

Embodiment 2

[0059] The driving device for multi-PDP data communication of a mobile broadband device provided in this embodiment is a further detailed description of the device solution described in the first embodiment. like image 3 As shown, the driving device provided in this embodiment specifically includes: RIL module 310, PDP management module 320, PDP control module 330, and device management module 340; wherein, RIL module 310 specifically includes Rild and Libril (RIL library).

[0060] For the technical solution described in the present invention: first, the function of the RIL module 310 is expanded, to be precise, the interface support of Libril to multiple PDPs is added, so that the Android system can obtain the PDP type and current PDP type of the access device currently supported by the system Active PDP or the like; Secondly, a PDP management module 320 is added, which is one of the core modules of the present invention, which is responsible for Libril's implementation of ...

Embodiment 3

[0071] like Figure 4As shown, the embodiment of the present invention provides a driving method for multi-packet data protocol PDP data communication of mobile broadband equipment, including:

[0072] Step S401, after receiving the function call request message based on data or configuration service from the Android system, call the PDP management process through the extended multi-PDP support interface;

[0073] Step S402, using the PDP management process to obtain the PDP type of the access device currently supported by the system and corresponding to the function call request, and call the PDP control process according to the PDP type;

[0074] Step S403, using the PDP control process to encapsulate the function call request message into a QMI command or convert it into an AT command, and after carrying the identification information of the corresponding access device in the command, call the device management process;

[0075] Step S404, using the device management proce...

Abstract

Disclosed are a device and a method of driving multi-packet data protocol (PDP) data communication for a mobile broadband device. The device comprises: a radio interface layer (RIL) module, used to receive a function invocation request message based on data or a configured service, invoke a PDP management module through an extended multi-PDP support interface; the PDP management module, used to acquire a PDP type of an access device corresponding to the function invocation request and currently supported by the system and trigger a PDP control module, and update and maintain a PDP resource state table; the PDP control module, used to encapsulate the function invocation request message into a QMI instruction or convert the instruction into an AT instruction, carry in the instruction identifier information of the access device and output the instruction to a device management module; and the device management module, used to send the instruction to the corresponding access device to perform PDP setup. The present invention is capable of supporting a multi-PDP data communication manner and increasing the access speed for a radio broadband device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a driving device and method for multi-PDP (Packet Data Protocol, packet data protocol) data communication of mobile broadband equipment.
