Patent ID: 8612593

Claim:
An apparatus, comprising: at least one processor; and at least one memory storing a computer program; in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least: store in the at least one memory a first list of private cells to which the apparatus is authorized to access, the first list comprising a cell identifier for each of the private cells; while under control of a serving first cell, determine from a transmission received from a neighbor second cell a physical cell identity of the neighbor second cell; and compare the determined physical cell identity to a second list stored in the at least one memory to determine whether the apparatus is authorized to access the neighbor second cell, the second list comprising a one-to-one mapping of physical cell identities to cell identifiers for at least some of the private cells to which the apparatus is authorized to access; wherein determining whether the apparatus is authorized to access the neighbor second cell comprises at least: checking the second list for a physical cell identity which matches the determined physical cell identity; selecting from the second list the cell identifier which maps to the matched physical cell identity; and concluding that the apparatus is authorized to access the neighbor second cell if the cell identifier selected from the second list matches a cell identifier within the first list.
