Title:
無線ローカルエリアネットワークにおける頻繁なネットワーク選択の回避方法
Document Type and Number:
Japanese Patent JP2007502064
Kind Code:
A
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.
