Abstract

In particular, systems and methods according to present principles configure physical eNodeB to have multiple virtual eNodeBs, where each virtual eNodeBs corresponds to a particular PLMN. Thus, each PLMN has its own virtual eNodeB which is hosted on a common shared physical eNodeB.

Claims

1. A method for sharing a radio access network node between multiple mobile networks, comprising:

providing a radio cell comprising a physical node;

supporting a plurality of virtual nodes on the physical node; and

at the radio cell, broadcasting;

data corresponding to a radio access service;

a plurality of network identifiers of respective multiple mobile networks, wherein each of the multiple mobile networks corresponds to at least one of the plurality of virtual nodes; and

a mobile network specific parameter applicable only for accessing a specific mobile network by user equipment associated with the specific mobile network, wherein the mobile network specific parameter includes at least one of the group consisting of;

a tracking area code, a cell identifier, and a cell barred indication.

2. The method of claim 1, further comprising supporting access technologies corresponding to one or more of the group consisting of:

MulteFire, Long Term Evolution (LTE), and 5G.

3. The method of claim 2, further comprising applying the mobile network specific parameter in communications with each of the respective multiple mobile networks.

4. The method of claim 3, further comprising controlling the radio cell with an eNodeB.

5. The method of claim 2, wherein broadcasting the mobile network specific parameter applicable for accessing the specific mobile network comprises broadcasting a mobile network specific parameter for a mobile network selected from one or more of the group consisting of:

public land mobile networks (PLMNs) and Neutral Host Networks (NHNs).

6. The method of claim 1, wherein broadcasting the mobile network specific parameter applicable for accessing the specific mobile network comprises broadcasting a mobile network specific parameter for a mobile network selected from one or more of the group consisting of:

public land mobile networks (PLMNs) and Neutral Host Networks (NHNs).

7. The method of claim 1, wherein broadcasting the plurality of network identifiers comprises broadcasting PLMN identifiers.

8. The method of claim 1, wherein broadcasting the mobile network specific parameter comprises broadcasting mobile network specific identifiers associated with the radio cell.

9. The method of claim 1, wherein broadcasting the mobile network specific parameter further comprises broadcasting at least one of the group consisting of:

a closed subscriber group indication and a closed subscriber group identifier.

10. The method of claim 1, further comprising applying the mobile network specific parameter in communications with each of the respective multiple mobile networks.

11. The method of claim 1, further comprising controlling the radio cell with an eNodeB.

12. A non-transitory computer-readable medium having stored thereon computer executable instructions which, when executed by a processor, cause the processor to:

support a plurality of virtual nodes on a physical node of a radio cell; and

broadcast;

data corresponding to a radio access service;

a plurality of network identifiers of respective multiple mobile networks, wherein each of the multiple mobile networks corresponds to at least one of the plurality of virtual nodes; and

a mobile network specific parameter applicable only for accessing a specific mobile network by user equipment associated with the specific mobile network, wherein the mobile network specific parameter includes at least one of the group consisting of;

a tracking area code, a cell identifier, and a cell barred indication.
