Embodiment Construction

[0026] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0027] figure 1 It is a schematic diagram of an embodiment of the network address allocation method of the present invention. Such as figure 1 As shown, the steps of the network address allocation method in this embodiment are as follows:

[0028] Step 101, after the user terminal establishes an association with the access point device, it sends an address allocation request message to the access control device, wherein the address allocation request message includes user identification information of the user terminal.

[0029] Step 102: After receiving the address allocation request message sent by the user terminal, the access control device adds the user identification information to the user list when judging that the user identification information is not included in the user list, and The...

Abstract

The invention discloses a network address allocation method and system. According to the network address allocation method, a user terminal sends an address allocation request to an access controller; when the access controller judges that a user list does not comprise user identification information, the user identification information is added into the user list, the attribute of the user identification information is set to be a private network address allocation state, and at the same time, a private network address is allocated for the user terminal; when the access controller receives an internet surfing request sent by the user terminal, after Portal certification is passed, the attribute is amended to be a public network address allocation state, and the user terminal is forced to be offline; the user terminal sends an address allocation request to the access controller again, and when the access controller judges that the attribute of the user identification information is in the public address allocation state, a public network address is allocated for the user terminal. Due to the fact that the user terminal can obtain the public network address allocated by the network side only when having access to the public network, waste of public network addresses can be avoided.

Description

technical field [0001] The invention relates to the communication field, in particular to a network-based address allocation method and system. Background technique [0002] Wireless Local Area Network (WLAN) technology is a local area network technology based on wireless transmission. Compared with wired network technology, it has the characteristics of flexibility, rapid network construction, and personalization. Applying this technology to the access network field of the telecommunication network can provide users with network access conveniently and flexibly. Occasions for temporary network construction and environments where it is difficult to use wired access. In recent years, the application of WLAN has developed rapidly, and it has been widely used in homes, enterprises and public areas. Currently, for operators, WLAN services have become the intersection of home broadband and mobile communications. On the WLAN construction network, in order to reduce the difficul...
