A Radio Local Area Network (RLAN) includes a Radio Access Network Internet Protocol (RAN IP) gateway that enables connectivity to the public Internet. The system may serve as a stand-alone system or be incorporated into a UMTS used with conventional Core Network, particularly for tracking and implementing AAA functions in the Core Network.
This application claims priority from U.S. Provisional Application No. 60/367,949, filed Mar. 26, 2002; U.S. Provisional Application No. 60/367,975, filed Mar. 26, 2002; U.S. Provisional Application No. 60/367,946, filed Mar. 26, 2002; U.S. Provisional Application No. 60/367,945, filed Mar. 26, 2002; U.S. Provisional Application No. 60/367,950, filed Mar. 26, 2002; and U.S. Provisional Application No. 60/367,948, filed Mar. 26, 2002, which are incorporated herein by reference as if fully set forth.
The present invention relates to wireless telecommunication systems and in particular to Time Division Duplex-Radio Local Area Network (TDD-RLAN) Code Division Multiple Access (CDMA) systems and connection and communication of such systems with the Internet.
The UTRAN is configured to provide wireless telecommunication services to users through User Equipments (UEs) via a radio interface known as UU. The UTRAN has base stations, known as Node Bs in 3GPP, which collectively provide for the geographic coverage for wireless communications with UEs. In the UTRAN, groups of one or more Node Bs are connected to a Radio Network Controller (RNC) via an interface known as Iub in 3GPP. The UTRAN may have several groups of Node Bs connected to different RNCs, two are shown in the example depicted in FIG. 2. Where more than one RNC is provided in a UTRAN, inter-RNC communication is performed via an Iur interface.
Under current 3GPP specifications as shown in FIG. 2, the Core Network, but not the UTRAN, is configured with connectivity to external systems such as Public Land Mobile Networks (PLMN), Public Switch Telephone Networks (PSTN), Integrated Services Digital Network (ISDN) and other Real Time (RT) services via an RT service interface. A Core Network will also support Non-Real Time services with the Internet. External connectivity of the Core Network to other systems, enables users using UEs to communicate via their Home UMTS Network, beyond the area served by the HN's UTRAN. Visiting UEs can likewise communicate via a visited UMTS Network, beyond the area served by the visited UMTS's UTRAN.
Under current 3GPP specifications as shown in FIG. 2, to provide support for both RT and NRT services from external sources for radio linked UEs in a 3GPP system, the UTRAN must properly interface with the CN which is the function of the Iu interface. To do this, the Core Network includes a Mobile Switching Centre (MSC) that is coupled to the GMSC and a Serving GPRS Support Node (SGSN) that is coupled to the GGSN. Both are coupled with the HRL and the MSC is usually combined with the Visitor Location Register (VLR).
The most significant signaling protocol on the over-the-air segment of the UTRAN is Radio Resource Control (RRC). RRC manages the allocation of connections, radio bearers and physical resources over the air interface. In 3GPP, RRC signaling is carried over the Radio Link Control (RLC) and Medium Access Control (MAC) UMTS protocols between the UE and RNC. Overall, the RNC is responsible for the allocation/de-allocation of radio resources, and for the management of key procedures such as connection management, paging and handover. Over the Iub interface, RRC/RLC/MAC messaging is typically carried on a Transport Layer via Asynchronous Transfer Mode (ATM), using the ATM Adaptation Layer Type 5 (AAL5) protocol over the ATM physical layer with intermediary protocols, such as Service Specific Coordination Function (SSCF) and the Service Specific Connection Oriented Protocol SSCOP, being used above AAL5.
The present invention provides for a Radio Local Area Network (RLAN) which includes a Radio Access Network Internet Protocol (RAN IP) gateway that enables connectivity to the public Internet. The system may serve as a stand-alone system or be incorporated into a UMTS used with conventional Core Network, particularly for tracking and implementing AAA functions in the Core Network.
The RLAN provides concurrent wireless telecommunication services for a plurality of user equipments (UEs) between UEs and/or the Internet. The RLAN includes at least one base station that has a transceiver configured to conduct code division multiple access (CDMA) wireless communications preferably time division duplex (TDD) CDMA wireless communications, with UEs in a selected geographic region. The RLAN also has at least one controller that is coupled with a group of base stations, which includes the base station. The controller controls the communications of the group of base stations. A novel Radio Access Network Internet Protocol (RAN IP) Gateway (RIP GW) is coupled with the controller. The RAN IP Gateway has a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) with access router functions for connection with the Internet.
The RLAN can include a plurality of base stations, each having a transceiver configured with a Uu interface preferably configured to conduct time division duplex (TDD) wideband code division multiple access (W-CDMA) wireless communications with UEs in a selected geographic region. The RLAN can also include a plurality of controllers that are each coupled with a group of base stations.
The invention further provides a telecommunication network having one or more radio network for providing concurrent wireless telecommunication services for a plurality of UEs and an associated CN for supporting AAA functions of UEs for which the telecommunication network, is a Home Network. One or more of the radio networks is a RLAN having a RAN IP Gateway that has a GGSN configured with a GI interface for connection with the Internet and is configured to communicate AAA function information to the CN. Preferably, the RLANs each have one or more base stations that have a transceiver for conducting TDD-CDMA wireless communications with UEs in a selected geographic region. Preferably, the RLANs have controllers coupled with the base stations. Preferably, the RLANs' RAN IP Gateways have a SGSN that is coupled with the respective controllers.

FIG. 10A illustrates IP packet data flow for a communication between a first UE having a wireless connection with the RLAN and a second UE outside the wireless service region of the RLAN where Mobile IP v4 is implemented on the GI interface between the RAN IP Gateway and the Internet. In such case, user data from the first UE is sent in IP packet format from the RAN IP Gateway of the RLAN through the Internet to the address provided by the second UE. The second UE communications are directed to the Home Address of the first UE which is maintained at the Core Network since in this example the first UE has the CN as its Home CN. The CN receives the IP data packets from the second UE and then the CN forwards the IP packets to the current location of the first UE which is maintained in the CN's HLR as the Forwarding Address (FA) of the first UE.
As shown in FIG. 14, multiple RNCs of the RLAN can be provided coupled with the SGSN subcomponent by an Iu-PS interface which includes sufficient connectivity to support the functions of the SGSN subcomponent. Where multiple RNCs are provided, they are preferably coupled by a standard Iur interface which utilizes an IP transport layer.
