Problems solved by technology

[0004] It can be seen from the solutions of the above prior art that the existing solutions for obtaining network configuration information are all based on the fact that the terminal device can provide the DHCP client function. If the terminal device cannot provide the DHCP client function or If the corresponding DHCP client function is turned off, the terminal equipment cannot successfully dial, and at most can only establish a connection, so that it cannot access the Internet for network data services, which affects the normal business development of the terminal equipment

Embodiment 1

[0021] In order to better describe the embodiment of the present invention, the specific embodiment of the present invention will be described in conjunction with the accompanying drawings, such as figure 2 Shown is a schematic flow chart of the method provided in Embodiment 1 of the present invention, the method comprising:

[0022] Step 21: Send a message for querying network configuration information to the wireless modem.

[0023] In this step 21, when the terminal device dials up and needs to carry out network data services, the network driver interface specification NDIS driver layer of the terminal device can send a message to the wireless modem to query network configuration information.

[0024] In the specific implementation process, when the terminal device dials up, the terminal device will first establish a connection with the wireless modem, and then the wireless modem will send a request to activate the PDP to the network side. After the activation is successfu...

Embodiment 2

[0034] Such as image 3 Shown is a schematic diagram of signaling interaction of a specific example cited in Embodiment 2, image 3 Middle: After the terminal device calls the WWAN API, the application program interface will call the WWAN Service interface layer (WWAN Service interface), and the driver layer of the terminal device will issue an object identifier (OID, Object Identifier) Signal, the driver layer (WWAN miniportdrivers) implements the functions required by the OID signal through one or more modem commands (AT commands) according to different OID signals issued by the upper layer. For example, a dial-up OID will be converted into an ATD dial-up AT command at the driver layer, and at the same time, the AT command will be sent to the wireless wide area network device (WWAN device) through the NDIS port to realize the interaction between the terminal device and the wireless wide area network device. Here, the wireless The role played by the wide area network device ...

Embodiment 3

[0038] Such as Figure 4 Shown is a schematic diagram of signaling interaction of another specific example mentioned in Embodiment 3, Figure 4 Middle: The driver layer of the terminal device sends the message of querying network configuration information to the WWAN device through the serial port (COM), thereby completing the interaction between the terminal device and the WWAN device. When the PDP is activated, the driver layer (WWAN miniport drivers) will automatically issue a request to obtain network configuration information after receiving the ACK confirmation signal sent by the WWAN device. These requests are sent to the WWAN device through the serial port using AT commands. ; The WWAN device will return the processing result of the AT command to the driver layer through the serial port; the driver layer will then provide the returned network configuration information to the application layer of the terminal device to complete the setting of the network address.

Abstract

The embodiment of the invention provides a method and a device for acquiring network configuration information. The method specifically comprises the following steps: when a terminal device dials a number and needs to develop a network data service, a network drive interface of the terminal device standardizes an NDIS drive layer for issuing a message of inquiring the network configuration information to a wireless modem; and the NDIS drive layer acquires the network configuration information returned by the wireless modem and provides the acquired network configuration information for an application layer of the terminal device. Therefore, the method and the device can effectively acquire the desired network configuration information under the situation that the terminal device does not provide the functions of a DHCP client, successfully dial the number, carry out the network data service by Internet access and ensure the development of the normal service of the terminal device.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method and device for acquiring network configuration information. Background technique [0002] At present, when the terminal device is performing network data services, after the dial-up packet data protocol (PDP, Packet Data Protocol) is activated, it needs to obtain the corresponding network configuration information, that is, IP address information and gateway information; and then the terminal device performs IP The setting of the address makes the dialing successful and guarantees the network data service. The above-mentioned terminal equipment can be a personal computer PC or other computer processing equipment. [0003] In the prior art, the static network configuration information can be manually set, and the network configuration information can also be obtained dynamically. For the situation of dynamically obtaining the network configuration information, the pri...
