Abstract

Flexible sharing of common radio access network (RAN) resources may pool unallocated resources. For example, sharing of the network resources may be static, e.g., the sharing contract may define a fixed percentage allocation of network resources that may not be modified without change in contract. The sharing of the network resource may also be dynamic and may accommodate the capacity needs of hosted operators on a real-time basis.

Claims

1. A method for managing a radio access network (RAN) capacity with a plurality of operators, the method comprising:

receiving, via a first brokerage control unit, a capacity query request from a participating operator of the plurality of operators requesting shared RAN resources;

determining available shared RAN resources;

sending a capacity query result granting the requested shared RAN resources from the available shared RAN resources to the participating operator; and

conducting an accounting of usage of shared RAN resources by the participating operator.

2. The method of claim 1, further comprising receiving information relating to the available shared RAN resources from a shared RAN.

3. The method of claim 1, further comprising providing information relating to the accounting of usage of shared RAN resources by the participating operator to a charging system.

4. The method of claim 3, further comprising causing the charging system to charge the participating operator for usage of shared RAN resources.

5. The method of claim 1, wherein the capacity query request is received from a second brokerage control unit via an X2 interface.

6. The method of claim 1, further comprising determining whether to trigger a charging event associated with a handover event.

7. The method of claim 6, further comprising determining whether to trigger the charging event as a function of a type of the handover event.

8. The method of claim 1, wherein the capacity query result comprises at least one of a location associated with an available shared RAN resource, a Quality of Service (QoS) attribute of an available shared RAN resource, or a time period of an available shared RAN resource.

9. The method of claim 1, wherein the shared RAN resources are associated with a virtualized RAN operator.

10. A system for managing a radio access network (RAN) capacity with a plurality of operators, the system comprising:

a first brokerage control unit configured to receive a capacity query request from a participating operator of the plurality of operators requesting shared RAN resources;

a second brokerage control unit in communication with the first brokerage control unit and configured to send the capacity query request to the first brokerage control unit;

a first charging system in communication with the first brokerage control unit; and

a second charging system in communication with the second brokerage control unit,

the first brokerage control unit configured to determine available shared RAN resources, to send a capacity query result granting the requested shared RAN resources from the available shared RAN resources to the participating operator, and to conduct an accounting of usage of shared RAN resources by the participating operator,

the first charging system configured to generate charging information as a function of the accounting of the usage of the shared RAN resources by the participating operator and to send the charging information to the second charging system.

11. The system of claim 10, wherein the first brokerage control unit and the second brokerage control unit are in communication via an X2 interface.

12. The system of claim 10, wherein the first brokerage control unit is configured to determine whether to trigger a charging event associated with a handover event.

13. The system of claim 12, wherein the first brokerage control unit is configured to determine whether to trigger the charging event as a function of a type of the handover event.

14. The system of claim 10, wherein the capacity query result comprises at least one of a location associated with an available shared RAN resource, a Quality of Service (QoS) attribute of the available shared RAN resource, or a time period of the available shared RAN resource.
