許容アクセス試行(Allowed access attempt)=f(アクセスサービスクラス)。
アクセス伝送確率(Probability of access transmission)=f(アクセスサービスクラス、RACHの目的)。
無線アクセスリソース割り当て(Radio access resource allocation)=f(時間及び/又は周波数及び/又はコード及び/又は…)。
許容アクセスリソース=f(RACHの目的)。
ランダム割り当て(Random Allocation)
ランダム割り当てにおいて、アクセスリソースは、RACHの任意の目的にランダムに割り当てられる。このような場合、RACHの1つの目的に特定の時間期間中により多くのアクセスリソースが割り当てられ、RACHの他の目的のために割り当てられたアクセスリソースがない場合があるため、他の目的への割り当て中にRACHの1つの目的のためのアクセスリソースに過大な負担が発生することがある。しかし、概して、RACHの各目的は、ランダム選択により負荷のの各シェアを得る。
均一割り当てにおいて、アクセスリソースは、順にRACHの利用可能な目的の間で同等に分けられる。前記アクセスリソースは、順番制で割り当てられる。RACHの第1目的のためのリソース割り当てがRACHの目的リストからランダムに選択される。次の割り当てのとき、前記選択は、循環順序(circular order)に従う。RACHの目的がアクセスリソースに割り当てられると、RACHのこの目的は前記リストのエンドに移動する。
加重割り当ては、均一割り当ての変形である。加重割り当ての場合、リストでRACHの各目的に加重値(weight)を割り当てることができるが、ネットワーク/オペレータが他のものよりRACHの一目的に2倍も多いアクセスリソースを割り当てることを希望する場合、RACHのこの目的は2の加重値を得る。このような場合、前記ネットワーク/オペレータは、ネットワーク容量及びRACHのある目的に対するアクセスリソース容量を処理できる。
−RACHの一部目的のためのアクセスは許容し、他の目的にはアクセスを拒否する場合、及び/又は
−特定サービス専用の無線リソースの利用可能性を制御する場合。
