Embodiment 1

[0123] An embodiment of the present invention provides a link establishment method, such as figure 1 As shown, the method may include:

[0124] Step 101, the data card configures address information for the host according to the identification information carried in the first routing message sent by the network side.

[0125] Specifically, the data card determines whether the routing request message sent by the host is received within a preset time, and the preset time starts counting from the first sending of the routing request message after the host negotiates with the data card; if After receiving the routing request message within the preset time, sending a second routing notification message to the host, the identification information carried in the second routing notification message is the same as the identification information carried in the first routing message sent by the network side The information is the same; if the routing request message is not received with...

Embodiment 2

[0145] An embodiment of the present invention provides a link establishment method, such as image 3 As shown, the method may include:

[0146] Step 301, the host receives a configuration result query message sent by the data card, and queries whether the link is established successfully.

[0147] Specifically, after the data card configures the address of the host according to the identification information carried in the first routing message sent by the network side, the data card sends a configuration result query message to the host, and the host receives the configuration result query message sent by the data card to check the configuration result. verify.

[0148] Step 302: The host sends a configuration result feedback message to the data card, and the configuration result feedback message includes: a configuration confirmation message or a configuration exception message.

[0149] Specifically, the host feeds back the configuration result to the data card through a ...

Embodiment 3

[0152] An embodiment of the present invention provides a link establishment method, such as Figure 4 As shown, the method may include:

[0153] Step 401, the data card sends a routing request message to the network side.

[0154] Specifically, the data card interacts with the network side to perform a boot registration and attachment process, during which a default PDN Context is activated. The data card actively sends the first routing message to the network side, and the network side sends the first routing notification message to the data card after receiving the first routing message.

[0155] It should be noted that the data card will keep sending the routing request message until it receives the first routing notification message.

[0156] Step 402, the data card receives the first route advertisement message sent by the network side, and saves the identification information carried in the first route advertisement message.

[0157] Specifically, the data card receiv...

Abstract

The embodiment of the invention discloses a link establishment method, a device and a system. Address information is configured to a host according to identification information carried in a first routing message sent by a network side; and a configuration result query message is sent to the host, wherein the configuration result query message is used for querying whether a link is established successfully or not according to the address information configured to the host.

Description

technical field [0001] The invention relates to the IPv6 technology in the Internet field, in particular to a link establishment method, equipment and system. Background technique [0002] Internet Protocol Version 6 (IPv6, Internet Protocol Version 6) has many advantages such as a large address space, an address structure that facilitates address aggregation, supports automatic address configuration, and supports host mobility. It has become a common basic protocol for the Internet and mobile communication networks. [0003] In the prior art, the IPv6 link establishment process includes: stateful address auto-configuration and stateless address auto-configuration. Both stateful auto-configuration and stateless auto-configuration require the Dynamic Host Configuration Protocol Version 6 (DHCPv6, Dynamic Host Configure Protocol Version 6) function supported by the host. Since the host is usually a custom-made operating system, it only has limited functions, or even does not ...
