FIELD: controlling user element arbitrary access to mobile communication system.
SUBSTANCE: proposed mobile communication system has B centers and service center that submits information pointing to number of user elements (UE) associated with group signaling in RNC. If UE responds to group signaling, RNC computes recoil window value proceeding from UE quantity pointing to recoil region required to control UE arbitrary access, inserts computed value in group signaling message, and transfers message to UEs. The latter randomly select recoil value in region considering recoil window value, wait for time period corresponding to this value, and transfer reply message, accordingly.
EFFECT: reduced number of conflicts and overloads in radio messages.
