Patent Images
1. A method of sharing a home base station among multiple Public Land Mobile Networks, PLMNs, comprising the following that are performed by the home base station:
- receiving from a User Equipment, UE, an identification of a selected PLMN among the multiple PLMNs, to which the UE is to be connected;
identifying an Internet Protocol security, IPsec, tunnel that is associated with a security gateway of the selected PLMN and an S1 or Iu interface that is associated with a home base station gateway of the selected PLMN; and
communicating between the UE and the selected PLMN using the IPsec tunnel that is associated with the security gateway of the selected PLMN and the S1 or Iu interface that is associated with the home base station gateway of the selected PLMN.

Abstract
A home base station receives from a wireless user equipment an identification of a selected Public Land Mobile Network, PLMN, among multiple available PLMNs to which the wireless user equipment is to be connected. The home base station identifies a communication path to a home base station gateway is associated with the selected PLMN and communicates with the selected PLMN that was identified over the communication path that was identified. The home base station may thereby be shared among multiple PLMNs. Related networks, methods and home base stations are described.

14. A home base station comprising:
-
a wireless transceiver that is configured to wirelessly communicate with wireless user equipment; a network interface that is configured to establish a communication path to a home base station gateway of a Public Land Mobile Network, PLMN; and a processor that is configured to receive from a wireless user equipment via the wireless transceiver, an identification of a selected PLMN among a plurality of available PLMNs to which the wireless user equipment is to be connected; the processor being further configured to identify a communication path to a home base station gateway that is associated with the selected PLMN, and to cause the network interface to communicate with the selected PLMN that was identified over the communication path that was identified. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A Public Land Mobile Network, PLMN, comprising:
-
a security gateway; a home base station gateway that is configured to communicate with a shared home base station that is shared among multiple PLMNs; and a home base station operation and maintenance system that is also configured to communicate with the shared home base station; the home base station operation and maintenance system being further configured to provide to the shared home base station a mapping table that includes a list of the multiple PLMNs to which the shared home base station can be connected and a corresponding Internet Protocol, IP, address of a corresponding security gateway of a respective PLMN in the list; and the home base station gateway being further configured to communicate with the shared home base station in response to receiving a message from the shared home base station that identifies an IP address that corresponds to the security gateway. - View Dependent Claims (24)
