Abstract

One embodiment is directed to a system comprising a first unit and remotely located second units. The first unit comprises a transport medium interface to produce a common transport signal from first and second wireless service provider signals and to communicate the common transport signal on a common transport medium. Each second unit comprises first and second equipment associated with first and second wireless service providers, respectively. The first and second equipment in each second unit produces a respective first and second wireless service signal to be radiated from at least one antenna associated with that second unit. The system further comprises a common network management system configured to: receive first and second control messages from first and second wireless service provider network management systems, respectively, and forward the first and second control messages to the first and second equipment, respectively, in the second units using the common transport medium.

First claim

What is claimed is:

1. A system comprising:
a first unit to receive a first wireless service provider signal from a first wireless service provider network operated by a first wireless service provider and to receive a second wireless service provider signal from a second wireless service provider network operated by a second wireless service provider;
wherein the first unit comprises a transport medium interface to produce a common transport signal from the first wireless service provider signal and from the second wireless service provider signal and to communicate the common transport signal on a common transport medium;
wherein the system further comprises a plurality of remotely located second units, each second unit connected to the common transport medium to receive the common transport signals from the common transport medium, and each second unit comprising first equipment associated with the first wireless service provider and second equipment associated with the second wireless service provider;
wherein, for each of the second units, the first equipment in that second unit produces a respective first wireless service signal to be radiated from at least one antenna associated with that second unit, the respective first wireless service signal being produced from the common transport signal; and
wherein, for each of the second units, the second equipment in that second unit produces a respective second wireless service signal using the second equipment included in that second unit to be radiated from at least one antenna associated with that second unit, the respective second wireless service signal being produced from the common transport signal; and
wherein the system further comprises a common network management system configured to:
receive first control messages from a first wireless service provider network management system operated by the first wireless service provider;
receive second control messages from a second wireless service provider network management system operated by the second wireless service provider;
forward the first control messages to the first equipment in the second units using the common transport medium; and
forward the second control messages to the second equipment in the second units using the common transport medium.

2. The system of claim 1 , wherein the common network management system is configured to:
receive third control messages from the first equipment in the second units via the common transport medium;
receive fourth control messages from the second equipment in the second units via the common transport medium;
forward the third control messages to the first wireless service provider network management system operated by the first wireless service provider; and
forward the fourth control messages to the second wireless service provider network management system operated by the second wireless service provider.

3. The system of claim 2 , wherein the common network management system filters the first, second, third, and fourth control messages to limit access by the first wireless service provider to status and control information associated with the first equipment in the second units and to limit access by the second wireless service provider to status and control information associated with the second equipment in the second units.

4. The system of claim 3 , wherein the common network management system comprises a statefull firewall that is configured to filter the first, second, third, and fourth control messages.

5. The system of claim 1 , wherein the common network management system is configured to appear to the first wireless service provider network management system to be an agent for the first control messages and is configured to appear to the second wireless service provider network management system to be an agent for the second control messages.

6. The system of claim 5 , wherein the common network management system is configured to appear to the first equipment in the second units to be a client for the first control messages and is configured to appear to the second equipment in the second units to be a client for the second control messages.

7. The system of claim 1 , wherein the common network management system comprises:
a local data store to maintain configuration information that defines access privileges for the first and second wireless service provider network management systems.

8. The system of claim 1 , wherein the common network management system comprises:
a local database to store data taken from poll and status information requests originated by the common network management system.

9. The system of claim 1 , wherein the first and second wireless service signals comprise first and second cellular service signals.

10. A method comprising:
receiving, at a first unit, a first wireless service provider signal from a first wireless service provider network operated by a first wireless service provider; and
receiving, at the first unit, a second wireless service provider signal from a second wireless service provider network operated by a second wireless service provider;
producing a common transport signal from the first wireless service provider signal and from the second wireless service provider signal;
communicating the common transport signal on a common transport medium to a plurality of second units;
at each second unit of the plurality of second units:
producing a respective first wireless service signal to be radiated from at least one antenna associated with that second unit, the respective first wireless service signal is produced using the first equipment included in that second unit from the common transport signal; and
producing a respective second wireless service signal to be radiated from at least one antenna associated with that second unit, the respective second wireless service signal is produced using the second equipment included in that second unit from the common transport signal;
receiving, at a common network management system, first control messages from a first wireless service provider network management system operated by the first wireless service provider;
receiving, at the common network management system, second control messages from the second wireless service provider network management system operated by the second wireless service provider;
forwarding the first control messages to the first equipment in the second units using the common transport medium; and
forwarding the second control messages to the second equipment in the second units using the common transport medium.

11. The method of claim 10 , further comprising:
receiving, at the common network management system, third control messages from the first equipment in the second units via the common transport medium;
receiving, at the common network management system, fourth control messages from the second equipment in the second units via the common transport medium;
forwarding the third control messages to the first wireless service provider network management system operated by the first wireless service provider; and
forwarding the fourth control messages to the second wireless service provider network management system operated by the second wireless service provider.

12. The method of claim 11 , further comprising filtering the first, second, third, and fourth control messages to limit access by the first wireless service provider to status and control information associated with the first equipment in the second units and to limit access by the second wireless service provider to status and control information associated with the second equipment in the second unit
