For current standards such as IETF Mobile IP or IEEE 8〇2.21, although these standards specify mobility-enabled messaging, they do not provide any implementation. In addition, some coordination is required between these mobile entities.

Measurement, multiple access quality of service (QoS), security, and power control. [The invention] relates to a mobile intermediary software Multiple RAT device, wherein the device provides users with access to different RAT networks, such as FDD networks and WLANs. In one embodiment, the device is a dual mode FDD/WLAN integrated wireless communication handset that includes TE module with mobile mediation software, application and protocol processor, and terminal interface (TI). In addition, this dual-mode FDD/WLAN integrated wireless communication phone is more A USIM, a UI module, and a protocol stack that are connected to a mobile media interface by a complex link, in another embodiment. In another embodiment, a 'multiple radio access technology device is provided for an application running in a terminal device. A terminal device of a plurality of wireless transmission media, wherein the device comprises a mobile mediation software core module, a mobile mediation software communication module, a driver, and a pluggable removable wireless communication device. The pluggable removable wireless communication device may be FDD/Wireless broadband (WiMAX) Personal Computer (PC) card. The mobile mediation software includes a set of functions including network detection, network selection, internet switching, parallel connection, measurement, multiple access service quality (Q〇S), Security and Power Control. [Embodiment] «When cited below, the term "wireless transmitting/receiving unit (WTRU)" includes but is not limited to user equipment (UE), mobile station, fixed or mobile subscriber unit, pager, Cellular phone, personal digital assistant (PDA), computer, laptop or any other device that can operate in a wireless environment User equipment. The present invention proposes a cross-layer function called mobile mediation software, which refers to 6 201032531 is a set of functions that can seamlessly move within different networks and provide support for multiple services. Network detection, network selection, network switching, parallel connection (when the device is connected to multiple access technologies simultaneously), measurement, multiple access QoS, security, and power control. The mobile media software is not in any specific In the agreement layer, and the mobile mediation software provides cross-layer interaction. This interaction with the application and access layer is done through the application interface (AI>I). Figure 1 shows the inclusion. A schematic view of a 3GPP dual mode FDD/WLAN integrated wireless communication handset 100 in a cellular telephone that functions as a mobile mediation softbox configured in accordance with the present invention. The 3GPP dual mode FDD/WLAN integrated wireless communication handset includes a mobile terminal (MT) module 1〇5, a terminal equipment (TE) module 11〇, and a subscriber service identification module (USIM) 115. The TE module 110 includes a mobile mediation software 120. According to the implementation, the MT module 1 〇 5, the TE module 11 〇, and the s IM 〗 5 can be combined on the same or separate wafers or processors. The MT module 1〇5 may include a UMTS FDD wafer 125. In addition, the 3GPP dual mode FDD/WLAN integrated wireless communication handset may also include the WLAN chip 130. As an example, although the UMTS FDD (ie, cellular network) and WLAN are respectively represented by the wafers 125 and 130 in FIG. 1, the 3GPP dual-mode FDD/WLAN integrated wireless communication handset 100 can support many other types. Access technology (eg IEEE 802.15, Handheld Digital Video Broadcasting (dvb-H), etc.). The mobile mediation software 120 integrates applications and multiple access networks. Since the mobile mediation software 120 coordinates handovers across different technologies, the mobile mediation software enables end-user applications to run seamlessly. For example, when switching between a cellular network and a WLAN, users of the 3GPP dual-mode 201032531 FDD/WLAN integrated wireless communication handset will not be aware of any interruptions in the frequency. The mobile mediation software 12 coordinates and controls mobility. For example, the mobile mediation software 12 can determine that the WLAN wireless interface is degrading and can initiate the cellular stack for handover in advance. The mobile mediation software 120 can then trigger a mobile ip to change the network path. Figure 2 shows the architecture of a 3Gpp dual-mode FDD/WLAN integrated wireless communication handset configured in accordance with the present invention. The handset 2 includes a TE module 205, a USIM 210, an MT module 215, and an IEEE 802.11 co-location stack 220.

The TE module 205 includes a mobile mediation software 225, an application and protocol processor 230, and a terminal interface (TI) 240. The TE module 2〇5, the USIM 210, the MT module 215, and the IEEE 802.11 protocol stack 220 can be combined on the same or separate wafers or processors as needed. The application and contract processor Mo executes the end user application 231 that the user ultimately uses. The end user application 231 can include voice over IP, video, and the like. In addition, the application and protocol processor 230 further includes a session initiation protocol (SIP) client 232, an IP protocol family 233, a mobile client 234, and an interface to the mobile mediation software 225 via the link 2804. 21 interface 235. As defined by the 3GPP standard, usiM21 includes an Authentication and Key Distribution (AKA) cellular security module 245 and an Extensible Authentication Protocol (EAP) AKA WLAN security module 250. The security modules 245 and 25A exchange relevant security information with the mobile mediation software 225 via link 2806. MT module 215 includes 3GPP FDD Non-Access Stratum (NAS) 255 to 201032531 - and 3GPP FDD Access Layer (AS) 265. NAS 255 includes 3GPP Functional Mobile Network (MN) 256, Call Control (CC) 257, Session Manager (SM) 258, General Packet Radio Service (GPRS) Mobility Manager (gmm) 259, and Radio Access Bearer Manager ( RABM) 260° RABM 260 controls all types of Radio Access Bearers (RAB) °NAS 255 also includes Alert Command Set Interpreter (ATC) 261, ATC Advanced Technology Attachment (ΑΤΑ) 262, IP Repeater 263, and Bits Stream repeater 264. ΑΤΑ 262 ensures that ATC commands are exchanged between the UI module 205 and the UI module 215. The 3GPP FDD AS 265 includes 3GPP L1/L2/L3 functions, such as FDD Physical Layer (PHY) 266, FDD Media Access Control Layer (MAC) 267, FDD Radio Link Control (RLc) 268, Packet Data Compression Protocol ( The PDCP) unit 269, the Broadcast and Multicast Control (BMC) unit 270, and the Radio Resource Control (RRC) 271. The IP repeater 263 exchanges IP packets/RABs with the PDCP unit 269. The bitstream repeater 264 exchanges with the FDD RLC 268 those packet/bitstream RABs (e.g., voice material, video telephony material, etc.) that are not based on π>. The ® 255 and AS 265 all include an IEEE 802.21 interface 235 that communicates with the mobile mediation software 225 via links 2803 and 2802, respectively. The IEEE 802.11 protocol stack 220 includes a logical link control (LLC) layer 221, an IEEE 802.11 MAC layer 122, an IEEE 802.11 PHY layer 123, and a Session Management Entity (SME) 224, all of which are via the IEEE 802.21 interface 235 and link 2801. And connected to the mobile mediation software 225 interface. As shown in FIG. 2, the function of the mobile mediation software 225 is to interact with other different entities within the 3GPP dual mode FDD/WLAN integrated wireless communication handset 100 via links 201032531 • 2801 to 2806. In addition, as previously described, the IEEE 802.21 interface 235 is included in the block 230 of the TE module 205, the 3GPP FDDNAS 255 and the 3GPP FDD AS 265 of the MT module 215, and the IEEE 802.21 protocol stack 220. Mobile mediation software 225 involves a set of functions that enable seamless mobility within different networks and support multiple services. One of these features is the network detection feature, which allows the terminal to recognize the characteristics of the surrounding network. Another of these features is the network selection feature, which enables the selection of the most appropriate access network for users based on QoS, system operators, user profiles, application needs, and more within the many re-acquisition networks. Another of these features is the inter-network handover feature for seamlessly switching from the previous network to the newly selected network. The purpose of this feature is to provide service continuity to the user. And this feature can interact with other mobile features such as Mobile IP. Another of these features is the Parallel Connection feature, which enables devices to be connected to multiple access technologies simultaneously to meet specific Q〇S applications. For example, voice calls can be processed via a cellular system, while file transfers are processed via WLAN. This parallel connection function interacts with the switching management and the IP layer for context transfer. Another feature of this is the measurement function, which collects measurements received from different AT networks and provides inputs to other mobile mediation software functions such as network selection, power management, and more. Another of these features is the Multiple Access QoS feature, which ensures that the selected network will handle the application's QoS needs. One of these functions is a security function that handles the security operations required to provide relevant security via AT and improve inter-network handover. For example, the security function can authenticate the user in advance, reducing the switching delay. Among them, there is a power control Wei, which coordinates the power control function of each access technology to improve the battery life of the device. . The current ffiEE 802.11 standard operates on the IEEE 802.11 MAC layer 222 and the IEEE 802.11 PHY layer 223 for interaction with the mobile 802.11 protocol stack 220 via the keyway 2801 to support media independent switching. IEEE 802.21 primitives for (MIH) services such as information, events, and commands. In addition, [ΕΕΕ 8〇2 21 primitives can also be introduced into existing or new IEEE 802.11 primitives. The interaction between the mobile mediation software 225 and the 3GPP FDD NAS 255 via link 2803 is dependent on IEEE 802.21 primitives (ie, resources, events, and commands) and certain NAS (SM and GMM), existing primitives. Direct mapping between. For the SM 258 for the mobile mediation software 125 and the GMM 259, they can work with the 3GPP FDD NAS 155 without requiring changes. For the interaction of the mobile mediation software 225 with the 3GPP FDD Access Layer (AS) 265 via the link 2802, there is a mapping between the IEEE 802.21 primitive and the primitive of the FDD Radio Resource Control (RRC) 271. For RRC 271 for mobile mediation software 225, it can work with 3GPP FDD AS 265 without requiring changes. 11 201032531 The interaction between the mobile mediation software 225 and the mobile IP client 234 via the keyway 2 includes two aspects. The aspect is that IEEE 802.21 can trigger the mobile Ip client 234 to speed up the handoff. For example, when an IEEE8G2.21 "Mih link disconnection" event occurs, the mobile mediation software 225 can trigger an event forwarding trigger to move the positive client, thereby triggering the registration to the foreign agent to obtain the care-of address and send " Link update,,. Doing so can reduce the delay in moving the switch.

On the other hand, there is an ongoing IETF mobile standard activity to support IEEE 802.21 messaging (e.g., information, events, and commands) over the IP between the TI 24G and the network via link 2805b. This method uses Mobile IP as a "vehicle" for transmitting positive 802.21 messages between the terminal and the road end, thereby minimizing the need to change this existing function. The mobile mediation software 225 interacts with the security functions 245 and 25〇 in the handset by means of a link to resolve security issues during the handover process. When switching between UMTS and WLAN networks, security must be guaranteed. Therefore, the mobile mediation software 22 UMTS security component (such as AKA cellular security module (4)) and wl = == such as E, AKAWL security module 25 〇) input, thereby ensuring the appropriate consistency. Existing AT commands from ΑΤΑ 262 can be used to pass commands to/from the mobile mediation software 225 via the keys ^(4) and 2805b. The mobile mediation software 225 interacts with applications and service enablement protocols such as the SIP client 232 via the link and the dirty view interface 235. For example, an application may have a fixed Q〇s requirement. Move 12 201032531 Body 225 can map this qoS requirement to the most suitable network. The mobile mediation software 225 interacts with the ieEE 802.11 protocol stack 220 via link 2801 to facilitate the handover process. Since the 3Gpp dual-mode FDD/WLAN integrated wireless communication handset 2〇0 moves from the area covered by the UMTS FDD network to the area covered by the IEEE 802.il network, the handover from FDD to IEEE 802.Π will be performed at this time. During the handover process, the mobile mediation software 225 can request; [EEE 802 11 protocol stack 22 initiates the associated program required to establish link 280. The present invention is directed to a mobile architecture in which the application processor is not on the same platform as the RAT network. This architecture is split between the pc and the pluggable removable wireless communication device, which introduces some complexity and imposes additional requirements on the mobile mediation software. A mobile intermediation architecture for such a device will be described herein, which may be, for example, a specific dual mode FDD/WiMAX device. Figure 3 shows the features of the mobile mediation software 225, which includes the mobile entity 305 and the service entity 310, and the mobile media includes functions that allow seamless movement within different networks and support multiple services. . Mobile entity 305 includes a relatively independent smart decision generation portion (i.e., mobile policy 315) and an interface portion (i.e., mobile enabler 320). The service entity 31〇 also includes a relatively independent smart decision generation component (i.e., service policy 325) and an interface component (i.e., service enabler 330). The service enabler 330 is defined in accordance with the Open Mobile Alliance (ΟΜΑ) or 3GPP protocols and programs. The modular design of the architecture enables the mobile mediation software 225 to support a growing number of different end user applications 335 and RATs. For example, if 13MAX32531 is added to the device as a new gAT, the WiMAX interface will be added to the mobile enabler 320, and the rest of the mobile media will remain unchanged.

The mobile mediation software 225 is at the top of the transport stack 34 (e.g., 3GPp, Global, Motion, System (GSM), WLAN, Long Term Project Evolution (LTE), etc.). Typically, there are two application types that interact with the mobile mediation software 225. One of the application types is an end user application (for example, voice over IP (VgIP), instant messaging, etc.). Another application is a South-level agreement (such as Mobile Ip or SIp). These applications coordinate the control of mobile and service mediation functions. For example, the End User Application 335 can use the Service and Mobile Application Programming Interface (API) in a coordinated manner via the Open API 345. The mobile mediation software 225 is not in any particular protocol layer. Instead, the mediation software provides cross-layer interaction, and its interaction with the end user application 335 and the transport stack is performed via open APIs 345 and 350, respectively. Figure 4 is a diagram showing the detailed structure of the mobile strategy 3is motion enabler 32G in the mobile entity 3〇5. The mobility policy 315 is a smart entity that handles multiple access mobility issues and provides policy and intelligence for different mobility' in addition it provides coordination of services (Q〇s). The entity is interfaced with the access layer via the mobile enabler 32 to monitor and control the underlying access technology stack. In addition, the $Mobile Strategy 315 Wings API is intended for end users to be ribbed. ~ Mobile Policy 315 includes the ability to enable and disable multiple services within different networks, including: υ Network Check Function 14 201032531 352, which allows the terminal to identify the secrets of the surrounding network. Guardian, 2) Network selection function 354, which can select the most suitable network of multiple access networks according to the characteristics of QoS, system operator, m-gut configuration file, application needs, and the like; 3). Inter-network switching function 356, the seamless switching of the network from the network to the newly selected network (the destination, port ET, J疋 provides service continuity for the user; this function and other mobiles such as mobile IP) Function in-interaction) = to multiple RAT's to satisfy QOS applications (for example, voice calls can be handled via cellular communication, while file transfers are via WLAN)! The parallel connection function interacts with the switching (H()) layer for context transfer; 5) the measurement function, the measurement results received from different tests, and other software functions for the transfer function Provide input 'eg network selection, power management, etc.; 6) multiple access Q〇s function, which ensures that the QoS requirements of the application are handled by the selected network; 7) security function 3 64, the function is in ra τ provides relevant security and improves the security operations required for inter-network handover (for example, the security function can authenticate the user in advance to reduce the handover delay); and 8) power to force ι 366 'this function for each A power control function of the access technology is coordinated to increase the battery life of the device. It should be noted that the mobile policy feature does not replace the existing mobile features in each RAT. For example, the inter-network handover handles the problem involving multiple access handovers' and it interacts with the handover function of each_access technology. Mobile enabler 320 is a "thin" functional layer that interfaces with different RAT interfaces. By using an open API, the mobile enabler 320 can be allowed to collect statistics from the RAT and transmit commands to these rats. In addition, it organizes and normalizes the information received from different RATs and provides a control/information trigger interface to the mobile policy entity 315k, thereby allowing control of the rat. The mobile enabler 320 receives and processes the measurements from the transport stack 34 (see Figure 3) and forwards the processed information to the mobile policy entity 315. In addition, it also sends commands and requests from the mobile policy entity 21G to the end user application 335 (see Figure 3). The mobile enabler 320 provides a thin layer to isolate the mobile policy 315 from any particular access network, thereby modularizing the design and facilitating expansion to different RATs. Figures 3 and 5 show an example of a service entity 310. Service Enabler 330 is a set of software functions and standardized APIs that enable developers of third party applications to define and build mobile device applications independent of the underlying transport technology. Typical examples of such allowed implementation techniques are DRM, instant messaging 510, and presence service 515. Using these examples separately in a typical implementation, the end user application opener can develop an application that allows DRM protected content to be sent via the instant messaging device only when certain rendering conditions are in place. The Service Enabler 330 allows the End User application to act on the enabled functions in a standardized manner. This allows for the development of an unlimited number of applications, where these applications are all supported by a supported transmission. The technology works in a transparent manner. The service policy 325 is a smart entity that performs service-related issues and provides a policy for the coordination of different applications supported by the service enabler 330. In accordance with another embodiment illustrated in Figure 6, the present invention is directed to a terminal device architecture 600' which includes a pluggable removable wireless communication device 605 that provides the functionality and functionality!

In the structure of Figure 10, the mobile mediation software core module resides at the MT end so that it can quickly use link-level activity. This allows them to respond quickly to such events and trigger an action. Since the core module is implemented on the MT platform and connected to the TE interface using a standard USB/WAN interface, its impact on the PC side is small. In addition, it is more likely and should be able to implement simple connections and configurations. The mobile mediation software core 800B can perform network detection, network selection, etc., and the mobile mediation software communication module 8〇〇a performs those that need to implement message exchange on the IP and call applications on other control stacks. Light interface (API) functionality. The mobile mediation software core module 800B and the mobile mediation software communication module 800A exchange messages via independent interfaces. The mobile mediation software core module 800B acts as the primary mobile mediation software function' whereby multiple services are supported by implementing control functions and IEEE 802.21 stitching events and services. For the mobile mediation software core module 22 201032531 The sewing service includes the allowable materials (4) (4) The operator, the user configuration = i access to the internal network according to the QGS, the user's request surface _ 勒 f (four) and other miscellaneous choices most in line with the mobile intermediary software core call Including the inter-network cut H force seal (four) I service also over-sealing switch.

For example, the security feature can authenticate users in advance to reduce handover delays. Another service that mobile mediation software core module 800B can provide also includes routing functionality. The mobile mediation software core module 8B routes control messages and data between the control application in the terminal device 600 and the communication protocol stack of the WiMAX 710 that can be plugged into the removable wireless communication device 〇5. The mobile mediation software communication module 800A can provide MIH message delivery. This function will accept the MIH message sent from the mobile mediation software core module 800B via the IP to the MIH server. The mobile mediation communication module 800A will then call the appropriate Apl and will send it in the IP stack available to the terminal device's computing platform. On the other hand, the mobile medium software communication module 800A should be able to receive the MIH message from the MIH server via IP and send this message to the mobile mediation software core module 800B. The mobile mediation software communication module 800A provides support for the interaction between the mobile mediation software core module 800B and other control protocols. This function will provide services for the mobile mediation software core module 800B, such as calling the MIP, the API on the SIP, etc. when the mobile mediation software core module 800B makes a request. The mobile mediation software communication module 800A can perform logical processing to support API calls and complete the process. Mobile mediation software interacts with IEEE 802.16 management entities to help implement handover procedures. At the time of switching from FDD to IEEE 802.16, 24 201032531 mobile mediation software can request the 802.16 management entity to initiate related procedures in order to establish an 802.16 link. In addition, direct mapping between IEEE 802.21 primitives (information, events, commands) and certain NAS (SM and GMM) primitives already exists. For SM and GMM for mobile mediation, they work with FDD NAS without change. Similar to FFD NAS, the above mapping is also provided between the ieee 802.21 primitive and the FDD RRC primitive. For the mobile media ®, it says that it can work with FDD AS without modification. The interaction between mobile mediation software and mobile IP is divided into two aspects. One aspect is that IEEE 802.21 can trigger a move ι to speed up the switch. For example, in the event of an 802.21 "MIH link disconnection, event, the mobile mediation software can forward the event trigger to the mobile ιρ client in the mobile terminal, thereby triggering the mobile terminal to register with the foreign agent, obtain the temporary address. (care 〇f address) and send "link update", . This reduces the delay in the mobile IP handover process. On the other hand, there is an ongoing IETF Mobile IP standard activity to support the messaging (information, events and commands) between the terminal and the network over IP. The method uses Mobile Ip as a "traffic tool" for communicating ΙΕΕΕ8〇2·21 messages between the mobile terminal and the network, thereby minimizing the need to change existing functions at both ends. Mobile mediation software interacts with applications and service enablement protocols such as SIP. For example, an application may have a certain Q〇s requirement. Mobile mediation software can map this Q〇S requirement to the most appropriate network. The mobile shimware interacts with the existing 25 201032531 security features in the mobile terminal to address the security issues of the handover process. In the existing security functions, there is no need to change. Existing AT commands can be used to pass data to and from the mobile mediation software. The mobile mediation software communication module 800A interacts with the IP protocol stack to send and receive MIH messages via ip. A message exchange interface will be established between the mobile mediation software core module 800B and the mobile mediation software communication module 8A. The mobile mediation software core module 800B sends a request to the mobile media software communication module 800A. The MIH message is sent to the MIH server via the IP. The mobile mediation software module 8〇〇a sends the IP message and waits for a response. The mobile media software communication module 8〇〇a receives the response returned by the MIH server. The response will then be forwarded to the mobile mediation software core module 800B. The mobile mediation software communication module 800A interacts with the MIP and the SIP stack. The mobile mediation software core module 800B can be moved to the mobile mediation on the "mess exchange" interface. The software communication module 800A sends a request to initiate a MIP or SIP interaction. Alternatively, the mobile mediation software communication module 8A can also initiate MIP or SIP interaction independently.
