2G/3G/LTE RAN Sharing.

ASTELNET offering shared Radio Access Network (RAN) controller with Multiple PLMN support feature which allows one to define cells broadcasting different PLMN codes within the same base station. The deployed Network can be multi vendor, multi technology (GSM, UMTS) system. These cells can be configured to work for different frequencies. The Network architecture involving two operators’ scenario (i.e. Operator A and Operator B) with their individual PLMNs on the active shared RAN (i.e. /Node-B/BTS and RNC/BSC).

Each cell in shared radio access network shall in the broadcast system information include information concerning available core network operators in the shared network. The available core network operators shall be the same for all cells of a Location Area in a shared UTRAN or GERAN network. The available core network operators shall be the same for all cells of a Tracking Area in a shared E-UTRAN network. A supporting UE decodes the broadcast system information and takes the information concerning available core network operators into account in network and cell (re- )selection procedures. Broadcast system information is specified in TS 44.018 [16] for GERAN, TS 25.331 [3] for UTRAN and TS 36.331 [11] for E-UTRAN.

For GERAN, as only non supporting UEs are considered, the information concerning available core network operators are never broadcast.
