Abstract
Access verification is adaptively done using an identifier of a first or a second length, by comparing a field of a node address that has the determined first or second length against a locally stored access list. At least the compared field of the node address is either added to a locally stored list of cell selection candidate nodes where the access list is allowed identifiers, or excluded from it where the access list is restricted identifiers. The node identifier is in three sections. The first section is service type, which the UE can use to determine whether or not it is restricted/allowed. The first length is the length of the second section, which is a service area ID of a group of network nodes. The second length is the length of the second section plus the third section, which identifies one node of the group of network nodes.
