`
`DESCRIPTION OF THE INVENTION
`
`This description should be written in the Inventor’s own words and shouldfollow this guideline:
`
`1. General purpose of the invention. State in general terms or summarize what the objectives of the inventions are.
`
`This invention proposes a multi-purpose mobile device that can be used for mobile communications and as a gateway for an
`indoor network. The intention is to have a single device that support mobile broadband access applications that can normally
`function like any other current mobile cellular handsets, i.e., supporting voice, multimedia applications such as video and audio
`download and other Internet applications such as web browsing, file download, VPN and Internet gaming. When the user
`terminal is located near to a display such as a TV, it should be able to relay the information to a different display device, in
`addition to that attached to the device itself.
`
`2. Description of the invention in detail (Including its operation, purpose, environment and how problems are solved).
`
`Currently, a mobile terminal may be able to support multimedia and Internet applications, but the data rate is very limited.
`However, as research on new technologies accelerates, new wireless communication standards are created to solve the problem of
`data rate supported. However, there is still a problem in the display of the information especially for multimedia applications. The
`display that is attached to the mobile device usually has a size limitation, due to form-factor, power consumption and cost issues.
`Thus the use of mobile device for video applications may still not be an attractive application to the customers. The idea here is to
`attach to the mobile terminal a device that could relay the downloaded data to a different display such as a TV, a computer
`monitor, the LCD screen of a laptop computer, the display on the dashboard of a car or through any projection device onto the
`walls or any passive screens.
`-
`
`On the other hand, in today’s home entertainment, video and TV signals are received through either terrestrial microwave
`broadcasting, Cable TV network or Satellite broadcasting. It is still limited in terms of coverage and cost of the infrastructure. In
`addition, there is still need for wiring of cables within the house in order to access the signal in more than one location. With this
`new device, broadcasting of TV, video or Video on Demand would be possible through the Internet Service providers. Since the
`device can either distribute multiple streams of signal to different displays simultaneously, or it can be easily moved to a different
`location to allow the signal to be showed on another display. Video conferencing can also be facilitated conveniently through the
`TV display or any other similar display or projections.
`
`The device contains a minimum of two air interfaces. The first air interface connects the mobile device to a mobile cellular
`network which provides services based on the user’s subscription. The second interface connects the mobile device to a display
`through another wireless connection. This air interface could be either a wireless personal area network connection, UWB or
`Bluetooth that can support the bandwidth requirements of the appliCation. Data that are downloaded from the server through the
`first wireless interface is transported within the device to the second air interface. The downloaded information is then formatted
`into an appropriate signal waveform and transmitted through the second air interface to the display. It is envisioned that the
`display contains a similar air interface that will receive and demodulate the signal transmitted by the mobile device. Fig. 1 shows
`a scenario of the application. Besides real-time streaming applications, it should be possible to store the downloaded information
`in some storage device for displaying at a different time.
`
`Moreover, the second interface can have more than one connection at the same time. For example, it can be communicating with
`the display screen and a wireless keyboard equipped with the same interface simultaneously. An employee who is traveling on a
`business or personal trip can still be able to access the company’s Intranet even without carrying a laptop computer. Today,
`wireless keyboard with an Infrared interface can be found in many hotels, but the purpose is mainly for Internet browsing through
`the TV. In this disclosure, the second interface here is a wireless connection with much better performance. The mobile device is
`the gateway that connects via Air Interface 11 the TV display and keyboard, to the remote server via Air Interface 11.
`
`It is also possible to have a third air interface that connects to a wireless LAN. Alternatively, the first air interface as described
`above could also be a WLAN interface. In this case, the connection to the mobile cellular network can be replaced by a nearby

`
`Using the example of evolution in voice communications, i.e., the popular, affordable and near-ubiquitous cellular
`communications has started to replace wireline based phone services gradually. In the future, it would also be possible for data
`communications to follow a similar trend, as more and more technical and practical issues are resolved. It would then become
`possible for anyone to carry only one mobile device and be able to access various data applications through a single service
`subscription, anywhere and anytime. For example, access to email, connection to company’s Intranet through VPN to access the
`files, perform research on the Internet, attend a webcast—online seminar and video conferencing.
`
`While the protocol architecture as depicted in Fig. 1 has been used in IEEE802 standards for many years, the technologies have
`been mainly used to support non-mobile applications. On the other hand, conventional mobile cellular technology has been using
`a protocol architecture that is significantly different from IEEE 802 standards. Currently, a new extension of the fixed wireless
`broadband access standard IEEE 802.16e to cover the mobility applications is in the development phrase. However, its main
`target form factor for the 802.16e device is PCMCIA card, which can be used in association of a Laptop or PDA. There is not any
`explicit indication on its implementation in a handset. In addition, while the standard is backward compatible with its fixed
`wireless counterpart, and standards activities have started to look at handoff issues between the various 802 technologies. The
`specific use of information relaying, the specify methodology and the actual application scenarios have not been specified in the
`same way as they are described in this disclosure.
`
`3. Describe the prior art, method or performance, of the invention (Including any related publicly available documentation,
`such as journal articles or patents).
`
`In 'recent years, there have been a lot of discussions on wireless devices that can be used for multimedia distribution. These are
`mostly in the form of a home gateway in which one of the interfaces is usually for short-range high bandwidth transmissions,
`while the other interface is usually connected to a DSL or cable Wire. The other class of devices, which is used for mobile cellular
`communication, is evolving into data centric applications from the traditional voice centric applications. Thus, the existing
`infrastructure is not optimized data and multimedia applications. There is usually a LCD display associated with the device to
`improve the support on multimedia application. There are new form factors such as PCMCIA card that are becoming increasingly
`popular. These cards can be inserted into a laptop computer or a PDA which are designed mainly for data applications. There are
`some handheld devices such as cell phones that are equipped with a Bluetooth interface. However, this is mainly used for
`connectivity purposes at a relatively lower data rate. It is thus not suitable for the information relaying function that is described
`in the current disclosure.
`
`4. What are the disadvantages of the prior art?
`
`The prior art either focuses on the first air interface, i.e., the connection to the mobile cellular network and applications
`terminating at the mobile device itself, or it focuses on the second interface, i.e., the wireless connection between the user
`terminal and the entertainment unit. The user terminal in the latter case is limited to short range, indoor applications.
`
`5. Describe how your invention, overcomes the shortcomings of the prior art.
`
`The prior art lacks a complete end-to-end solution and full mobility. Multiple devices are usually required for different
`environments. This invention consists of one mobile device which has multiple interfaces that allows it not only to select the best
`to use in a different environment, but also to use two or more air interfaces simultaneously in supporting an application. It also
`makes it more practical for a mobile device to support different types of applications, based on the specific nature of each type of
`applications. There have been emphases on the co-existence of different technologies, instead of trying to combine the different
`technologies, each of which is designed and customized for a different application environment, to complete an end-to-end link
`that can comprise of different technologies.

`
`Mobile Device initiates a connection to the
`obile cellular network through Air Interface l to
`
`start an application,
`e.g., Video download, video conferencing or
`VPN connection
`
`
`
`
`
`
`
`
`Mobile Cellular Network assigns to the Mobile
`
`
`Device a traffic channel or authorize the
`connection, in case of a Broadcasting application
`
`Mobile Device initiates a connection via the second air interface
`
`
`to another device e.g., a display screen, TV, computer monitor or
`terminal, a laptop computer or a projector, which is equipped
`with a transceiver module for the second air interface standard
`and thus can communicate with the mobile device via the
`second air interface.
`
`
`
`
`
`After connection for the first and second air interface is
`
`
`established, the mobile device starts to receive data
`
`
`from the first air interface and forward the data packets
`to the second air interface, through a bridge layer,
`
`
`which is a layer above the MAC layers and is common
`to the two air interfaces.
`
`
`
`
`The other device such as a display receives the
`
`forwarded data through the second air interface, and
`
`
`display it on the screen. For video conferencing
`
`
`applications, a video camera can be attached to the
`display and also send the images to the mobile device
`via the second air interface in the reverse link direction.
`
`
`
`
`
`The mobile device demodulates the signal received
`from the video camera via the second air interface,
`and forwards it to the first air interface through a
`common layer that is above the MAC layer.
`
`
`
`
`
`The reverse link data is received by the
`Base station through the first air interface.
`
`
`
