     FIELD OF INVENTION 
       [0002]    This application is related to wireless communications. 
       BACKGROUND 
       [0003]    Currently the mobile Communication industry is moving toward convergence and interworking between various wireless technologies, (e.g., third generation partnership project (3GPP)-based, 3GPP2-based, IEEE 802.11 WiFi, IEEE 802.16 WiMax, and Fixed Broadband Access, etc.). The main goal of this convergence is to allow subscribers to access their home-based services anywhere via any technology. In order to support this goal, the 3GPP standards have defined the interworking architecture, (i.e., evolved packet system (EPS)), shown in  FIG. 1 . 
         [0004]    The functions of the mobility management entity (MME) include non-access stratum (NAS) signaling and security, inter core network (CN) node signaling for mobility between 3GPP access networks, roaming, authentication, or the like. The serving gateway is a note that terminates the interface towards an evolved universal terrestrial radio access network (EUTRAN). The packet data network (PDN) gateway is a node that terminates the SGi interface towards the PDN. The functions of the PDN gateway include mobility anchor for mobility between 3GPP network and non-3GPP networks, UE Internet protocol (IP) address allocation, etc. 
         [0005]    For non-3GPP accesses, the EPS includes an evolved packet data gateway (ePDG). The ePDG includes functionalities of a PDG according to 3GPP standards that specify inter-working between 3GPP systems and a WLAN. Untrusted non-3GPP access requires ePDG in the data path. 
         [0006]    To support roaming and mobility, the EPS architecture defines following interfaces: 
         [0007]    S1-MME, S1-U, S3, S4, S10, S11: These are defined in 3GPP TS 23.401. 
         [0008]    S2a: It provides a user plane with related control and mobility support between a trusted non-3GPP IP access and a gateway. 
         [0009]    S2b: It provides a user plane with related control and mobility support between an ePDG and a gateway. 
         [0010]    S2c: It provides a user plane with related control and mobility support between a user equipment (UE) and a gateway. This reference point is implemented over trusted and/or untrusted non-3GPP access and/or 3GPP access. 
         [0011]    S5: It provides user plane tunneling and tunnel management between a serving gateway and a packet data network (PDN) gateway. It is used for serving gateway relocation due to UE mobility and in case the serving gateway needs to connect to a non-collocated PDN GW for the required PDN connectivity. 
         [0012]    S6a: This interface is defined between an MME and a home subscriber server (HSS) for authentication and authorization. 
         [0013]    S6c: It is a reference point between a PDN gateway in a home public land mobile network (HPLMN) and a 3GPP authentication, authorization and accounting (AAA) server for mobility related authentication if needed. This reference point may also be used to retrieve and request storage of mobility parameters. 
         [0014]    S6d: It is a reference point between a serving gateway in a visited public land mobile network (VPLMN) and a 3GPP AAA proxy for mobility related authentication if needed. This reference point may also be used to retrieve and request storage of mobility parameters. 
         [0015]    S7: It provides transfer of quality of service (QoS) policy and charging rules from a PCRF to a policy and charging enforcement point (PCEF). 
         [0016]    S8b: It is a roaming interface in case of roaming with home routed traffic. It provides a user plane with related control between gateways in the VPLMN and the HPLMN. 
         [0017]    S9: It indicates the roaming variant of the S7 reference point for the enforcement in the VPLMN of dynamic control policies from the HPLMN. 
         [0018]    SGi: It is a reference point between a PDN gateway and a packet data network. The packet data network may be an operator external public or private packet data network or an intra operator packet data network, (e.g., for provision of IP multimedia subsystem (IMS) services). This reference point corresponds to Gi and Wi functionalities and supports any 3GPP and non-3GPP access systems. 
         [0019]    Wa: It connects an untrusted non-3GPP IP access with a 3GPP AAA server/proxy and transports access authentication, authorization and charging-related information in a secure manner. 
         [0020]    Ta: It connects a trusted non-3GPP IP access with a 3GPP AAA server/proxy and transports access authentication, authorization, mobility parameters and charging-related information in a secure manner. 
         [0021]    Wd: It connects the 3GPP AAA proxy, possibly via intermediate networks, to the 3GPP AAA server. 
         [0022]    Wm: This reference point is located between a 3GPP AAA server/proxy and an ePDG and is used for AAA signaling (transport of mobility parameters, tunnel authentication and authorization data). 
         [0023]    Wn: This is a reference point between an untrusted non-3GPP IP access and an ePDG. Traffic on this interface for a UE initiated tunnel has to be forced towards the ePDG. 
         [0024]    Wx: This reference point is located between a 3GPP AAA server and an HSS and is used for transport of authentication data. 
         [0025]    In order to perform interworking operation effectively between 3GPP systems and non-3GPP systems, it would be desirable to exchange information pertaining to different systems between a UE and a network. 
       SUMMARY 
       [0026]    A method and apparatus for providing capability information and core network information to support interworking between a 3GPP network and a non-3GPP network are disclosed. A UE sends UE capability information pertaining to the non-3GPP network such as IEEE 802.11 interworking wireless local area network (I-WLAN), an IEEE 802.16 WiMAX network, a fixed broadband network, etc. to a 3GPP network. The 3GPP network may send core network information pertaining to the non-3GPP networks to the UE.

     DETAILED DESCRIPTION 
       [0031]    When referred to hereafter, the terminology “UE” includes but is not limited to a wireless transmit/receive unit (WTRU), a mobile station, a fixed or mobile subscriber unit, a pager, a cellular telephone, a personal digital assistant (PDA), a computer, or any other type of user device capable of operating in a wireless environment. 
         [0032]      FIG. 2  shows a UE  200  including multiple radio units for operating both in a 3GPP network and a non-3GPP network. The UE  200  includes multiple radio units, (i.e., a 3GPP radio unit  202  and at least one non-3GPP radio unit  204 ). A controller  206  in the UE  200  controls the radio units  202 ,  204  and performs functions for handover between the 3GPP network and the non-3GPP network. The non-3GPP network may be an IEEE 802.11 interworking wireless local area network (I-WLAN), an IEEE 802.16 WiMAX network, a fixed broadband network, or the like. 
         [0033]    The UE  200  and the 3GPP network exchange UE capability information and core network information in order to facilitate the handover between the 3GPP network and the non-3GPP network. The 3GPP standards define UE capability information and core network information to be exchanged between the UE and the 3GPP network for facilitating communication within the 3GPP network (3GPP TS 25.331). The conventional 3GPP information elements are extended to provide UE capability information and core network information pertaining to the non-3GPP networks to facilitate interworking between the 3GPP network and the non-3GPP network. 
         [0034]      FIG. 3  is a flow diagram of an example process  300  of exchanging UE capability information and core network information pertaining to the non-3GPP network. It should be noted that the steps in the process  300  may be performed in different order and some steps may be performed simultaneously or may be omitted. Upon power up, a UE camps on a 3GPP control channel (step  302 ). Information regarding available systems within a cell, (e.g., GSM, GPRS, UMTS, or the like), is transmitted via the 3GPP control channel. The UE receives, and stores, a list of available systems (step  304 ). 
         [0035]    Based on the user preference or UE pre-configuration, the UE registers with one of the 3GPP networks, and may request additional information about the available systems within the cell (step  306 ). The UE also provides the 3GPP network with the UE capability information pertaining to the non-3GPP networks (step  308 ). The UE capability information pertaining to the non-3GPP network includes UE multi-mode/multi-radio access technology (RAT) capability, UE radio access capability, UE measurement capability, or the like, which will be described in detail below. 
         [0036]    The 3GPP network receives registration information and the UE capability information, and performs authorization and authentication procedures to ensure the integrity of the information provided by the UE (step  310 ). The 3GPP network may provide the UE with the core network information pertaining to the non-3GPP networks (step  312 ). The core network information may include at least one of core network domain identity, core network domain system information, domain specific access restriction, domain specific access restriction parameters, intra domain non-access stratum (NAS) node selector, NAS system information, public land mobile network (PLMN) type, and radio access bearer (RAB) identity, etc., which will be described in detail below. The 3GPP network may also provide the UE with the core network capability information. 
         [0037]    After receiving the core network information, the UE may make a decision on the preferred network based on a preconfigured selection mechanism (step  314 ). The 3GPP network may direct the UE to select other network (step  316 ). 
         [0038]    The UE sends UE multi-mode/multi-RAT capability information (defined in 3GPP TS 25.331 10.3.3.41) to the 3GPP network. Information pertaining to the non-3GPP network is added to the UE multi-mode/multi-RAT capability information. The new information includes at least one of support of trusted interworking wireless local area network (I-WLAN), support of untrusted I-WLAN, support of WiMAX (trusted), support of fixed broadband (trusted), support of I-WLAN-UTRAN handoffs, support of WiMAX-UTRAN handoffs, support of fixed broadband-UTRAN handoffs, etc. Table 1 shows UE multi-mode/multi-RAT capability information including these new information elements (underlined) pertaining to the non-3GPP technologies. In the need column tables below, MP stands for mandatory present and OP stands for optional.

         [0041]    The 3GPP network sends CN information including CN domain identity (defined in 3GPP TS 25.331 10.3.1.1). The CN domain identity identifies the type of core network domain. The CN domain identity may further include types of non-3GPP domains (e.g., trusted or non-trusted: I-WLAN domain, WiMAX domain). The new information elements (underlined) are shown in Table 4.

         [0044]    The 3GPP network provides the UE with intra domain NAS node selector (defined in 3GPP TS 25.331 10.3.1.6). The intra-domain NAS node selector information element carries information to be used to route the establishment of a signaling connection to a CN node within a CN domain. This information element may further include information pertaining to the non-3GPP networks, such as routing parameters for the I-WLAN (trusted or untrusted), WiMAX (trusted), fixed broadband network, etc. The intra domain NAS node selector including the new information elements (underlined) is shown in Table 7.

         [0048]    The UE reports its measurement capabilities to the network (as defined in 3GPP TS 25.331 10.3.3.21). The UE may indicate to the 3GPP network through the measurement capability information element whether the UE requires downlink or uplink compressed mode in order to perform measurements on IEEE 802.11 WLAN or IEEE 802.16 WLAN. The measurement capability information including the new information elements (underlined) is shown in Table 11.
