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

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.
