Abstract

Novel tools and techniques that can provide wireless service for multiple service providers from a single, multi-service provider wireless access point. In an aspect, a multi-service provider wireless access point might communicate with a plurality of wireless devices, each associated with a different wireless carrier, and route communications from each device to the appropriate carrier (and/or, similarly, transmit communications from each carrier to the appropriate wireless device). In this way, for example, a single wireless access point could provide service to cellphones of subscribers of a number of different carriers. Such a wireless access point can provide enhanced efficiency and reduced cost, along with the ability to provide higher service for a number of wireless carriers.

Claims (59)

1. A method of providing wireless service for multiple service providers from a single access point, the method comprising:

providing a multi-service provider wireless access point having one or more radios to communicate with wireless devices and an uplink interface to provide an uplink connection to a plurality of wireless service providers, wherein the multi-service provider wireless access point further comprises a plurality of antennas;

receiving, at the multi-service provider wireless access point, a communication from a wireless device;

collecting, at the multi-service provider wireless access point, an identifier of the wireless device from the communication;

identifying, from the identifier of the wireless device, a wireless service provider serving the wireless device;

receiving, at the multi-service provider wireless access point, one or more subsequent communications from the wireless device;

routing, from the multi-service provider wireless access point, the one or more subsequent communications to the identified wireless service provider, over the uplink connection, and through a telecommunication service provider core network associated with the identified wireless service provider and accessible to subscribers of the identified wireless service provider;

mapping each of a plurality of sub-bands to one or more respective wireless service providers;

identifying a sub-band allocated to the wireless service provider serving the wireless device;

mapping each of the plurality of sub-bands to one or more of the plurality of antennas of the wireless access point;

identifying which one or more antennas of the plurality of antennas provides enhanced communication performance for the identified sub-band that is allocated to the wireless service provider serving the wireless device; and

communicating with the wireless device using the sub-band assigned to the wireless service provider via the identified one or more antennas that provides enhanced communication performance for the identified sub-band that is allocated to the wireless service provider serving the wireless device.

2. The method of claim 1 , wherein the one or more radios comprise one or more software defined radios.

3. The method of claim 1 , wherein the one or more radios consist of a single radio.

4. The method of claim 3 , wherein the plurality of wireless service providers collectively communicate on a plurality of frequency bands, and wherein the single radio is configured to communicate on the plurality of frequency bands.

5. The method of claim 3 , wherein the single radio employs orthogonal frequency-division multiple access (“OFDMA”) modulation.

6. The method of claim 1 , wherein identifying which one or more antennas of the plurality of antennas provides enhanced communication performance for the identified sub-band comprises identifying which one or more antennas provides enhanced communication performance for the identified sub-band based on at least one of specific radio frequency characteristics or antenna length.

7. The method of claim 1 , wherein identifying the sub-band as a frequency range that is allocated to the identified wireless service provider comprises:

accessing a database correlating wireless service providers with allocated frequency ranges; and

searching the database for a record corresponding to the identified wireless service provider.

8. The method of claim 1 , wherein the one or more radios comprise a long term evolution (“LTE”) radio.

9. The method of claim 1 , wherein the one or more radios comprise a WiFi radio.

10. The method of claim 1 , wherein the identifier is a mobile telephone number.

11. The method of claim 1 , wherein the identifier is an electronic serial number (“ESN”).

12. The method of claim 1 , wherein the identifier is a media access control (“MAC”) address.

13. The method of claim 1 , wherein the uplink connection comprises an Ethernet connection.

14. The method of claim 1 , wherein the uplink connection comprises a passive optical network (“PON”) circuit.

15. The method of claim 1 , wherein the uplink connection comprises a digital subscriber line (“DSL”) connection or a Data Over Cable Service Interface Specification (“DOCSIS”) connection.

16. The method of claim 1 , wherein routing one or more subsequent connections to the identified wireless service provider comprises:

addressing the one or more subsequent connections to a network address corresponding to the identified wireless service provider; and

transmitting the one or more subsequent communications over the uplink connection.

17. The method of claim 1 , wherein identifying a wireless service provider comprises:

accessing a database correlating wireless device identifiers with wireless service providers; and

searching the database for a record containing the identifier of the wireless device.

18. The method of claim 17 , wherein the database identifies a mobile switching center (“MSC”) of the identified service provider, the method further comprising:

updating the database to identify a different MSC as serving the wireless device; and

routing communications from the wireless device to the different MSC.

19. The method of claim 18 , wherein the identified wireless provider is a first wireless service provider, and wherein the different MSC is operated by a second wireless service provider having a relationship with the first wireless service provider.

20. The method of claim 17 , further comprising:

storing the database at the multi-service provider wireless access point.

21. The method of claim 17 , wherein the database is remote from the multi-service provider wireless access point.

22. The method of claim 21 , wherein accessing the database comprises accessing the database over the uplink connection.

23. The method of claim 1 , further comprising:

registering the wireless device with a wireless network operated by the wireless service provider, based on the received communication from the wireless device.

24. A multi-service provider wireless access point, comprising:

one or more radios and a plurality of antennas to communicate with wireless devices;

an uplink interface to provide an uplink connection to a plurality of wireless service providers;

a processor in communication with the one or more radios and the uplink interface; and

a non-transitory machine readable medium having encoded thereon a set of instructions executable by the processor to perform one or more operations, the set of instructions comprising:

instructions to receive a communication from a wireless device;

instructions to obtain, from the communication, an identifier of the wireless device;

instructions to identify, from the identifier of the wireless device, a wireless service provider serving the wireless device; and

instructions to receive one or more subsequent communications from the wireless device;

instructions to route the one or more subsequent communications to the identified wireless service provider, over the uplink connection, and through a telecommunication service provider core network associated with the identified wireless service provider and accessible to subscribers of the identified wireless service provider;

instructions to map each of a plurality of sub-bands to one or more respective wireless service providers;

instructions to identify a sub-band allocated to the wireless service provider serving the wireless device;

instructions to map each of the plurality of sub-bands to one or more of the plurality of antennas of the wireless access point;

instructions to identify which one or more antennas of the plurality of antennas provides enhanced communication performance for the identified sub-band that is allocated to the wireless service provider serving the wireless device; and

instructions to communicate with the wireless device using the sub-band assigned to the wireless service provider via the identified one or more antennas that provides enhanced communication performance for the identified sub-band that is allocated to the wireless service provider serving the wireless device.
