Closed Subscriber Group
LTE supports the existence of cells which are only available for a limited set of EEC- A closed Subscriber Group (CSG). In order to prevent attempts to register on the UES CSG cells on which they do not have access to, up to the CSG supports white list, that is, a list of The CSG that identity was granted access to UES. CSG white list can be transferred to UE the top layers, or update after successful access to cell CSG. Whom facilitate the latter, support of the EEC “manual selection” CSG cells that are not in the CSG white list. Manual selection of the top layers may be requested, on the basis of a text string broadcasting in the cell. LTE also supports hybrid cells. As cell-cell CSG hybrid broadcast The CSG; they are available as cell CSG, EEC, whose GCF white lists include CSG’s personality and how normal cells, other EEC.
Cell Selection Anyone
If the UE is able to find the cells selected PLMN, performs “any cell option “. In this case the UE performs the normal idle mode: monitor paging, the acquisition of SI, the cells selected. In addition, the UE regularly tries to find the corresponding cells on other frequencies or rats (i.e. not listed in SI). If the UE supports voice service is able to find the appropriate cells, you should try to find acceptance in each cell RAT supported, regardless of the cell selected priorities that are broadcast. The UE is not the opportunity to receive MBMS in that State.
How Grouped UE Closed Subscriber Works in LTE
In LTE, a Grouped UE Closed Subscriber Group (CSG) allows a set of user equipment (UE) to access a particular cell based on predefined subscription settings, even if the cell is typically closed to others. A CSG is often used in private or restricted areas, such as enterprise networks or certain regions, where only specific UEs are permitted to connect. When a UE belongs to a CSG, it can access a closed cell that would normally reject other UEs. The cell uses the Grouped CSG ID to identify the allowed UEs. The UE must have the proper CSG membership information, which is stored on the SIM or in the network, to gain access to these restricted cells.
