Abstract

To facilitate, e.g., determination of access rights in a shared network context, a telecommunications network transmits, in a broadcast channel over an air interface, an access group eligibility message to a user equipment unit. The access group eligibility message enables the user equipment unit to ascertain, on a basis of access group to which the user equipment unit belongs, whether the user equipment unit is eligible to operate in a cell for which the access group eligibility message is transmitted. The telecommunications network also includes a core network node which, classifies the user equipment unit in at least one of plural access groups. Further, the core network node generates an access group classification message which advises the user equipment unit as to which of the plural access groups the user equipment unit belongs. Upon receipt of the access group classification message, the user equipment unit stores an access group classification obtained from the access group classification message in a memory at the user equipment unit. An access controller of the user equipment unit (upon receiving the access group eligibility message) compares the stored access group clas…
