FIELD: information technologies. ^ SUBSTANCE: initialisation and control of access for communication units comprises assignment of identifiers to sets of units, at the same time identifiers may be used to control access to limited access units, which provide certain services only to predetermined specified sets of units. In some aspects unit initialisation may include provision of a unique identifier for sets from one or more units, such as limited points of access and access terminals, which are authorised to receive a service from limited access points. Access control may be provided by an operation of a limited access point and/or a network unit. In some aspects unit initialisation includes provision of a list of preferable roaming for a unit. In some aspects a unit may be initialised with the help of a list of preferable roaming using a beacon radio signal of self-initialisation. ^ EFFECT: improved access control. ^ 70 cl, 28 dwg |
