Embodiment 1

[0045] Such as 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 P...

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. Such as 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 ...

Embodiment 3

[0071] Such as 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 pr...

Abstract

The invention discloses a device and a method for driving multi-packet data protocol (PDP) data communication of mobile broadband equipment. The device comprises a radio interface layer (RIL) module, a PDP management module, a PDP control module and an equipment management module, wherein the RIL module is used for receiving function call request information based on data service or configuration service, and calling the PDP management module through an extended multi-PDP support interface; the PDP management module is used for obtaining PDP types of pieces of access equipment which are currently supported by a system and correspond to function call requests, triggering the PDP control module and updating a maintained PDP resource state table after PDPs are successfully created or destroyed; the PDP control module is used for packaging the function call request information as Qualcomm MSM interface (QMI) instructions or converting the function call request information to attention (AT) instructions, carrying identification information of the access equipment in the instructions and then outputting the instructions to the equipment management module; and the equipment management module is used for sending the instructions to the corresponding access equipment to create the PDPs. The device and the method can support a multi-PDP data communication manner, thereby increasing the access speed of the wireless broadband equipment.

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.
