Method for preventing wireless local area network from frequent network selection interaction
First Claim
1. A method for preventing frequent network selection interaction of a Wireless Local Area Network (WLAN), the method comprising:
- (a) after a wireless connection between WLAN user equipment (UE) and a WLAN Access Network has been established, the WLAN UE delivering network selection information to the WLAN Access Network during an interaction of an access authentication initiated by a network side or the WLAN UE;
(b) the network side deciding whether the network selection information belongs to an operating network of mobile communications with which the WLAN Access Network connects, and if yes, sending the access authentication request from the WLAN UE to the operating network of mobile communications identified by the network selection information; and
(c) if the network selection information does not belong to the operating network, deciding whether information of the operating network is allowed to be issued based on a number of times for which the information has been issued in a defined period of time, and if yes, issuing the information of the operating network to the UE, and recording the number of times for which the information has been issued, and otherwise, stopping issuing the information of the operating network.

Abstract
The present invention discloses a method for preventing Wireless Local Area Network (WLAN) from frequent network selection interaction. Every time it is needed to issue the information of operating networks of mobile communications, decide according to the number of times for which the information has been issued in a defined period of time whether the information of operating networks of mobile communications is allowed to be issued. If allowed, go ahead with issuing the information of operating networks of mobile communications and record the number of times for which the information has been issued; otherwise, stop issuing the information. When the decision period changes, update the issuing record. When a request for issuing information is received after the issuing has been stopped, discard the request or issue the information after a delay. This invention can prevent WLAN from suffering congestion induced by the network selection mechanism or attacks launched by malicious UEs.
