It should be noted that the home gateway in the embodiment of the present invention is the subscriber subscription bandwidth information obtained in the process of requesting the IP address from the BRAS. The home gateway may use DHCP (Dynamic host configuration Protocol) or PPP (Point to Point Protocol) when requesting an IP address from the BRAS. The basic flow of requesting an IP address using these two protocols is similar, and the following description will use DHCP as an example.
Firstly, the home gateway sends a DHCP discover message in a broadcast mode, all the BRAS receiving the DHCP discover message can receive the DHCP discover message, all the BRAS receiving the DHCP discover message send a DHCPoffer message to the home gateway, the DHCP offer message carries an IP address which can be allocated to the home gateway, the home gateway generally only processes the received first DHCP offer message, and sends a DHCP request message to the BRAS sending the first DHCP offer message, wherein the DHCP request message carries the IP address required by the home gateway.
The IP address request message of the step is a DHCP request message sent to the BRAS by the home gateway, and the step adds request information of the user signed bandwidth information in the DHCP request message.
102. And the home gateway receives an IP address confirmation message sent by the BRAS, wherein the IP address confirmation message carries the user subscription bandwidth information.
It should be noted that, after the home gateway sends the DHCP request to the BRAS, the home gateway receives the DHCP ack packet sent by the BRAS, and carries the use lease information of the IP address required by the home gateway.
The IP address confirmation message in the step is a DHCP ack message sent to the BRAS by the home gateway, and the user subscription bandwidth information is added into the DHCP ack message in the step.
103. And the home gateway acquires the user subscription bandwidth information from the IP address confirmation message.
After receiving the DHCP ack message, the home gateway can obtain the use lease information of the IP address from the DHCP ack message, and can obtain the user subscription bandwidth information from the DHCP ack message. The home gateway requests the IP address and acquires the user signed bandwidth information, and then the home gateway uses the requested IP address to connect the network, so that the process of acquiring the user signed bandwidth information does not influence the normal internet access of the user.

In addition, the home gateway is the user subscription bandwidth information obtained from the second optional field of the IP address confirmation message.
For example, the user subscription bandwidth information is obtained from the option 226 of the IP address confirmation message.
It should be noted that the user subscription bandwidth information in the IP address confirmation message is encrypted user subscription bandwidth information in XML (Extensible Markup Language) format.
When the uplink available bandwidth is 750 and the downlink available bandwidth is 10000, the user subscription bandwidth information in the XML format specifically includes:
< BANDWIDTH > (Start tag: Bandwidth)
< NAME > bandwidth </NAME > (NAME is bandwidth)
< LINK >0</LINK > (0 is used to indicate the upstream available bandwidth)
< VALUE >750</VALUE > (upstream available bandwidth 750Kbps)
< LINK >1</LINK > (1 for indicating upstream available bandwidth)
< VALUE >10000</VALUE > (the downstream available bandwidth is 10000Kbps)
</BANDWIDTH > (end tag: BANDWIDTH)
