Abstract

The present invention provides a Radio Local Area Network (RLAN) that includes a Radio Access Network Internet Protocol (RAN IP) gateway that enables connectivity to the Internet. The RAN IP gateway is configured to use predetermined interfaces to couple with Radio Network Controllers (RNCs) and base stations to provide an IP connection to the Internet for user equipment.

Claims

1. A radio local area network (RLAN) comprising:

a first base station having a transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications with user equipments (UEs);

a first Radio Network Controller (RNC) coupled with said first base station for controlling base station communication;

a Radio Access Network Internet Protocol (RAN IP) Gateway having a subset of a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) for connection with the Internet, said RAN IP Gateway coupled with said first RNC via an Iu-PS interface using a stacked, layered protocol having a lower transport layer configured to use Internet Protocol (IP); and

a Voice Gateway being coupled with said first RNC using stacked, layered protocol communications having a lower transport layer configured for Internet Protocol (IP).

9. The RLAN according to claim 1 wherein said RAN IP Gateway has a subset of a Serving GPRS Support Node (SGSN) that is coupled with said first RNC.

10. The RLAN according to claim 1 comprising:

a plurality of base stations that each have a transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications with UEs in a selected geographic region; and

a plurality of RNCs that are each coupled with a group of base stations of said plurality of base stations using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP); and

said RAN IP Gateway has a subset of a Serving GPRS Support Node (SGSN) that is coupled with said plurality of RNCs using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP).

11. The RLAN according to claim 10 wherein said RNCs are coupled with each other using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP).

12. The RLAN according to claim 10 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform code division multiple access (CDMA).

13. The RLAN according to claim 10 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform time division duplex (TDD) code division multiple access (CDMA).

14. The RLAN according to claim 1 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform code division multiple access (CDMA).

15. The RLAN according to claim 1 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform time division duplex (TDD) code division multiple access (CDMA).

2. The RLAN according to claim l wherein:

said first RNC is coupled with said first base station using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP).

3. The RLAN according to claim 2 comprising:

a plurality of base stations, each having a transceiver configured with a Uu interface for conducting Third Generation Partnership Project (3GPP) wireless communications with UEs in a selected geographic region;

said first RNC being coupled with said base stations using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP).

4. The RLAN according to claim 3 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform code division multiple access (CDMA).

5. The RLAN according to claim 3 wherein said transceiver for conducting Third Generation Partnership Project (3GPP) wireless communications is configured to perform time division duplex (TDD) code division multiple access (CDMA).

6. The RLAN according to claim 2 further comprising:

a second RNC coupled with a second base station using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP); and

said first RNC being coupled with said second RNC using a stacked, layered protocol connection having a lower transport layer configured to use Internet Protocol (IP).

7. The RLAN according to claim 6 wherein said RAN IP Gateway has a subset of a Serving GPRS Support Node (SGSN) that is coupled with said RNCs.

8. The RLAN according to claim 6 wherein said RAN IP Gateway has a subset of a Serving GPRS Support Node (SGSN) that is coupled with said first RNC.

16. A radio local area network (RLAN) comprising:

a first base station having a transceiver for conducting code division multiple access (CDMA) wireless communications with user equipments (UEs);

a first Radio Network Controller (RNC) coupled with said first base station for controlling base station communication; and

a Radio Access Network Internet Protocol (RAN IP) Gateway having a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) for connection with the Internet, said RAN IP Gateway coupled with said first RNC via an Iu-PS interface using a stacked, layered protocol having a lower transport layer configured to use Internet Protocol (IP);
