WLANと他のネットワークとの間の相互接続のためには、認証、許可、課金(Authentication, Authorization, and Accounting:以下AAAと略す)、QoSの提供、移動性の制御など、いくつかの大きな問題を解決する必要がある。それらの問題の大部分は、例えば、許可/参加の制御、QoSや移動性の機能の展開など、ポリシーに基づく解決策が望まれるものである。
相互接続では、時折、WLANがユーザ加入者情報に基づく決定(例えば、承認コントロール)を行う必要がある。この情報は、ユーザのホーム・ドメインに格納され、一般に共有されることは許されないので、WLANは決定を下すためにホーム・ドメイン・サーバ(104)に依存しなければならない。しかし、ホーム・ドメインが、相互接続する異なるWLANで使用される技術に関して、必ずしも詳細な知識を持つとは限らないので、ホーム・ドメイン・サーバ(104)は、WLAN内のリソース管理エンティティに対して正確な指示を与えることは不可能である。さらに、いくつかの適用(例えば、承認コントロール)では、ローカル・ネットワーク情報を必要とし、ホーム・ドメインにおける決定を妨げられる。
