Embodiment 1

[0111] This embodiment provides a method for obtaining an Internet Protocol address, see figure 1 , the method specifically includes:

[0112] 101: Detect the connection information of the data packet protocol PDP with the network side.

[0113] 102: If it is detected that the PDP connection information between the mobile broadband device and the network side changes, obtain identification information, where the identification information is used to identify the PDP connection information between the mobile broadband device and the network side.

[0114] 103: Send the identification information to the host, so that the host obtains the IP address of the host according to the identification information.

[0115] To sum up, in the method provided by the embodiment of the present invention, the mobile broadband device sends identification information to the host, so that the host obtains the IP address of the host according to the identification information. Compared with the p...

Embodiment 2

[0117] This embodiment provides a method for obtaining an Internet Protocol address, see figure 2 , the method specifically includes:

[0118] 201: Receive identification information sent by the mobile broadband device, where the identification information is used to identify PDP connection information between the mobile broadband device and the network side.

[0119] 202: Set the value of the status identifier included in the host according to the identifier information.

[0120] 203: If the value of the state identifier is not the identifier corresponding to the disconnected state, obtain the IP address of the host.

[0121] To sum up, the method provided by the embodiment of the present invention receives the identification information sent by the mobile broadband device, and sets the value of the status identification included in the host according to the identification information, as long as the value of the status identification is not corresponding to the disconnecte...

Embodiment 3

[0123] An embodiment of the present invention provides a method for obtaining an Internet protocol address. Among them, the host is connected to the mobile broadband device, and the mobile broadband device supports IPv4 and IPv6 dual stacks. First, there is no PDP connection between the mobile broadband device and the network side. If the mobile broadband device and the network side first establish an IPv4 PDP connection, then establish an IPv6 PDP connection, the host can obtain the IPv4 address corresponding to the IPv4 PDP connection and the IPv6 address corresponding to the IPv6 PDP connection through the method of this embodiment. see image 3 , the method includes:

[0124] 301: The mobile broadband device detects the PDP connection information with the network side. If it detects that an IPv4 PDP connection is established with the network side and there is no IPv6 PDP connection between the mobile broadband device and the network side, determine that the mobile broadba...

Abstract

The invention discloses a method for obtaining the internet protocol address, and belongs to the technical field of communication. The method comprises the following steps of: detecting PDP (Packet Data Protocol) connection information with a network side; if the detected PDP connection information with the network side changes, obtaining identifier information, wherein the identifier information is used for identifying the PDP connection information of the network side and a mobile broadband device; transmitting the identifier information to a host, and enabling the host to obtain the IP (Internet Protocol) address of the host according to the identifier information. In the method provided by the invention, the mobile broadband device transmits the identifier information to the host, so that the host can set the values of state identifiers of the host according to the identifier information, wherein the values of different state identifiers correspond to different connection states of the mobile broadband device and the network side, no matter the mobile broadband device builds the IPv4PDP (Internet Protocol version 4 PDP) connection and what the order or the length of time interval of the IPV6PDP connections, and the host needs not to disconnect the network during the process of obtaining the IPv4 address and the IPv6 address, so that the data service for the users cannot be interrupted.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method, device and system for obtaining an Internet protocol address. Background technique [0002] In the field of communication, IPv4 (Internet Protocol version 4, Internet Protocol version 4) network and IPv6 (Internet Protocol version 6, Internet Protocol version 6) network coexist, so mobile broadband (Mobile Broad Band) devices must support both IPv4 and IPv6 dual stack, wherein the host can obtain the IPv4 address and the IPv6 address through the mobile broadband device, and connect to the IPv4 network and the IPv6 network. [0003] At present, the prior art provides a method for a host to obtain an IPv4 address and an IPv6 address through a mobile broadband device, which can be specifically: the host is connected to the mobile broadband device, if the mobile broadband device establishes an IPv4PDP (Packet Data Protocol, packet data protocol) with the network side Protocol)...
