Embodiment Construction

[0027] The core idea of ​​the present invention is: use the interactive signaling between the user terminal and the network to carry the network selection information of the user terminal, then, when the current user terminal accesses the WLAN access network, it can use the carried network selection information, Identify the mobile communication operator network to be accessed by the user terminal, and connect the current user terminal to the selected network for access authentication and subsequent operations.

[0028] The network selection information can be placed in a separately set field in the access authentication signaling, or in a user identification field in the access authentication signaling. Generally, the user identification field is defined in the format of a network access identification (NAI), including two parts, a user name and a domain name. The user name and domain name are separated by a separator @, which can be expressed as: user name@domain name. In th...

Abstract

The invention discloses a method for processing user terminal network selection information in a wireless local area network (WLAN). Access authentication signaling of information, the user terminal network selection information can be placed in the user identification field defined in the network access identification (NAI) format. The invention enables the user terminal to select an appropriate mobile communication operating network to access when accessing from a WLAN connected with multiple mobile communication operating networks.

Description

technical field [0001] The invention relates to network access technology, in particular to a method for processing user terminal network selection information in a wireless local area network (WLAN). Background technique [0002] As users have higher and higher requirements on wireless access rates, a wireless local area network (WLAN, Wireless Local Area Network) emerges at the historic moment, which can provide high-speed wireless data access within a small range. Wireless local area network includes a variety of different technologies. A technical standard that is widely used at present is IEEE802.11b, which uses the 2.4GHz frequency band, and the maximum data transmission rate can reach 11Mbps. IEEE 802.11g and Bluetooth (Bluetooth) technology are also used in this frequency band. , Among them, the highest data transmission rate of 802.11g can reach 54Mbps. Other new technologies such as IEEE 802.11a and ETSI BRAN Hiperlan2 both use the 5GHz frequency band, and the hig...
