 are three states in system information block 3 (SIB3) reserved for cell reservations: cell barred, cell reserved for operator use and cell reserved for future extension. Access control controls the connection setup. If the call has already been set up and the mobile is moving in the network the access control has no effect on the connected mode users making handovers from one cell to another. The access control is used for load control purposes to prevent certain services being established in certain cells. Access class specific restrictions are sent in system information block 3. The access control does not affect emergency calls, if not specifically prevented. Cell Re-selection The cell (re-)selection procedure is used in idle mode and in connected mode states of Cell_FACH, Cell_PCH and URA(UTRAN routing area)_PCH. The target is to find the most suitable cell to camp on. If the VE does not have stored information on the target cell must use the 'initial cell selection' procedure, or otherwise the 'stored information cell selection' procedure. Cell Re-selection in WCDMA The mobile obtains neighbour cell information from the BCCH, which consists of possible cell individual offsets, scrambling code, carrier frequency and radio access technology (RAT). In the cell re-selection procedure the UE tries to find a better cell to camp on. The neighbour cell measurements are started only when the measurement criteria are met. The mobile measures the serving cell all the time, but it measures neighbouring cells only when the serving cell c/No falls below the measurement criteria. The measurement criteria can be set differently for different neighbour types: Same carrier neighbours (intrafrequency) Sintrasearch Different carrier neighbours (interfrequency) Sintersearch GSM neighbours (intersystem) SsearchRAT When the neighbour cells are evaluated it must first be verified that they fulfil the minimum quality criteria, also called the S-criteria. The S-criteria (Squal) consist of a minimum acceptable quality and/or a minimu
