Network sharing
A wireless communication system includes one or more base stations able to divide resources between multiple network operators sharing the base station. A shared base station is configured to monitor a contribution to the load on the base station associated with network operators sharing the base station resources and to provide the determined contribution to the load to one or more other base stations for use in load balancing between the base stations.
1. A long term evolution (LTE) base station, for an LTE Radio Access Network that is shared by at least two operators, each operator being associated with a respective Public Land Mobile Network (PLMN), the base station comprising:
a processor configured to generate a signal which includes access class barring (ac-barring) per PLMN information in system information block 2 (SIB2); and
a transceiver circuit configured to broadcast the signal,
wherein the ac-barring per PLMN information provided in the SIB2 comprises an ac-BarringInfo information element (IE) and an ac-Barring for mobile originating data (ac-BarringForMO-Data) IE, in association with information indicating a PLMN of one or more of the at least two operators.
2. A method for a long term evolution (LTE) base station for an LTE Radio Access Network which is shared by at least two operators, each operator being associated with a respective Public Land Mobile Network (PLMN), the method comprising:
generating a signal which includes access class barring (ac-barring) per PLMN information in system information block 2 (SIB2); and
broadcasting the signal,
wherein the ac-barring per PLMN information provided in the SIB2 comprises an ac-BarringInfo information element (IE) and an ac-Barring for mobile originating data (ac-BarringForMO-Data) IE, in association with information indicating a PLMN of one or more of the at least two operators.
3. A User Equipment that communicates with a long term evolution (LTE) base station for an LTE Radio Access Network shared by at least two operators, each operator being associated with a respective Public Land Mobile Network (PLMN), the User Equipment comprising:
a transceiver circuit configured to receive a signal that includes access class barring (ac-barring) per PLMN information in system information block 2 (SIB2); and
a processor configured to determine whether access to a cell is barred,
wherein the ac-barring per PLMN information provided in the SIB2 comprises an ac-BarringInfo information element (IE) and an ac-Barring for mobile originating data (ac-BarringForMO-Data) IE, in association with information indicating a PLMN of one or more of the at least two operators.
4. The User Equipment according to the claim 3 , wherein the cell is identified by the information indicating a PLMN.
5. A method for a User Equipment that communicates with a long term evolution (LTE) base station for an LTE Radio Access Network shared by at least two operators, each operator being associated with a respective Public Land Mobile Network (PLMN), the method comprising:
receiving a signal that includes access class barring (ac-barring) per PLMN information in system information block 2 (SIB2); and
determining whether access to a cell is barred,
wherein the ac-barring per PLMN information provided in the SIB2 comprises an ac-BarringInfo information element (IE), and an ac-Barring for mobile originating data (ac-BarringForMO-Data) IE, in association with information indicating a PLMN of one or more of the at least two operators.
6. A method according to the claim 5 , wherein the cell is identified by the information indicating a PLMN.
