<p>Access of a user terminal (UE) to a cell (C) in a cellular communication network candidate for access by the user terminal (UE) is controlled by broadcasting (200) within the cell (C) at least one signal (for instance a flag) for reception by the user terminal (UE), selected out of:
- a) a start signal (LU_Start; CellRegistrazion_Start) which, if the location area code or LAC broadcast by the cell (C) or the cell (C), respectively, are not included in a list of forbidden code or cells, indicates to the user terminal (UE) to start immediately a procedure (202) for location update or registration with said cell (C), respectively;
- b) a reset signal (LAC_Forbidden-Reset; CellForbiddenList_Reset) which, if the location area code broadcast by the cell or the cell (C), respectively, are included in said list of forbidden codes or cells, indicates to the user terminal (UE) to remove the code or the cell (C), respectively, from the list and to start immediately a procedure (202) for location update or registration with said cell, respectively; and
- c) the combination of the signals under a) and b).
Preferred application to femto-cell networks ( Figure 1 ).</p> |
