`ABSTRACT
`
`A tWo-Way data communication device such as a data ready
`cellular telephone, a tWo-Way pager, or a telephone com
`municates via a tWo-Way data communication network With
`a server computer on a computer network that has an
`interface to the tWo-Way data communication netWork, i.e, is
`Coupled to the tWO-Way data Communication network For
`@Xample, the Computer network can be a Corporate Wide area
`netWork, a corporate local area netWork, the Internet, or any
`Combination of Computer networks- The two-Way data Com‘
`munication device utiliZes a client module to transmit mes
`sage including a resource selector chosen by the user to a
`server on a server computer on the computer netWork. The
`server processes the message and transmits a response over
`the tWo-Way data communication netWork to the client
`module. The client module interprets the response and
`presents the response to the user via a structured user
`interface. Alternatively, the user transmits a request that
`directs the server to transmit the response to the request to
`another location or to another user.

`This invention relates generally to data communications,
`and in particular to two-way data communication devices
`including a cellular telephone, a two-way pager, and a
`telephone that permit a user to interface with and interact
`with a server on a computer network.
`2. Description of Related Art
`For at least the last five years, the wireless communication
`industry has tried to merge computing with wireless com-
`munications. This industry wide effort has held the promise
`of bringing software intelligence to telecommunication
`devices including mobile wireless communications devices
`such as cellular telephones and two-way pagers as well as
`standard telephones.
`After years of research and development, and hundreds of
`millions of dollars’
`investment by some of the largest
`companies in the field such as Motorola, AT&T, Sony,
`Matsushita, Phillips and IBM, the results have been nothing
`but disappointing. Typically, the intelligent communication
`devices resulting from these efforts include both the hard-
`ware necessary for a computer module and the hardware for
`a wireless communications module. Examples of such prod-
`ucts are Simon from IBM and Bell South, MagicLink from
`Sony, and Envoy from Motorola.
`Fundamental design and cost problems arising directly
`from the approach taken by the designers of these intelligent
`communication devices have limited widespread market
`acceptance of these devices. The combination of a wireless
`communication module with a computing module leads to a
`device that is too bulky, too expensive, and too inflexible to
`address the market requirements.
`The combination of the two modules is too large and too
`heavy to fit in a user’s pocket. Pocket size is a key require-
`ment of the mobile communication market which remains
`
`unmet by these devices
`In addition, the cost of these devices is close to the sum
`of the cost of the computer module and of the communica-
`tions module, which is around a one thousand dollar end-
`user price. Market research indicates that the market for
`intelligent wireless communications devices is at prices
`around $300. Even with a 20% compound cost decline, it
`
`2
`would take five years for the combination units to meet
`today’s customers’ price requirements.
`It
`is therefore
`unlikely that devices designed by combining a computer and
`a wireless module, no matter how miniaturized and cost
`reduced, can satisfy the cost requirement of the market
`during this decade.
`To succeed in the market place, intelligent wireless com-
`munication devices must be able to support a wide variety of
`applications specific to each market segment. Typically,
`these applications must be added to the device by the
`end-user after purchase. Thus, the device must provide a
`method for loading the initial application and for subsequent
`updating of the application.
`The price sensitivity for intelligent communication
`devices and the size limitations means that an intelligent
`communication device cannot support the amount of core
`memory (RAM), a hard disk or non-erasable memory, or a
`traditional floppy disk drive, commonly found on comput-
`ers. These limitations close the traditional routes for deliv-
`
`10
`
`15
`
`20
`
`ering new applications or updates to intelligent communi-
`cations devices.
`
`As a result, the current crop of intelligent communication
`devices run only the few applications which were burned
`into their ROMs at the factory or which are contained in a
`ROM card plugged into a slot designed for this purpose. This
`scheme lacks the flexibility needed to run the thousands of
`applications required to address the fragmented require-
`ments of the market and provides no simple method for
`updating the applications after the device has been sold.
`Two other communication oriented attempts at bringing
`intelligence to telephones are Short Messaging Service
`(SMS) and Analog Display Service Interface (ADSI). SMS
`specifies how messages are delivered to and from a cellular
`telephone and how the cellular telephone should store the
`messages. SMS also defines some simple processing which
`the cellular telephone can perform on the message, such as
`calling a telephone number embedded in the message.
`SMS’s architecture is similar to that of paging networks
`with the difference that devices implementing the SMS
`architecture operate over the control channel of the cellular
`telephone network. SMS is deployed primarily in Europe
`over the GSM network.
`
`SMS messages are not delivered in real time. The time
`delays can range from 30 seconds up to 10 minutes, which
`makes SMS unsuitable for real time applications. The main
`purpose of SMS is the delivery of messages. SMS does not
`specify an application protocol or cellular telephone appli-
`cation module which further restricts its usefulness in run-
`
`ning applications on cellular telephones. After a few years of
`deployment in Europe, SMS implementations have been
`limited to notification services such as two-way paging and
`voice mail notification.
`
`SMS as a medium is unsuited to building applications
`which allows the retrieval, manipulation, and storage of
`information. This is the reason why the industry giants have
`not turned to SMS in their quest to add intelligence to
`cellular telephones, but have consistently attempted to com-
`bine a computer module with a wireless communications
`module.
`
`ADSI was designed as an extension to Interactive Voice
`Response Systems. ADSI allows a smart telephone with a
`small screen to display prompts to assist users in choosing
`among various options. By using visual prompts instead of
`cumbersome voice prompts, ADSI is thought to make the
`use of interactive voice services easier and faster.
`
`ADSI allows data to be sent from the service provider to
`the telephone in the form of screens. ADSI also allows the

`telephone to respond through touch tone signaling with a
`special coding to describe the full alphanumeric character
`set. With ADSI, a telephone is primarily a passive device.
`Services send text screens to the telephone, and the tele-
`phone sends back short strings indicating the choices the
`user made from the text screen.
`
`ADSI makes no provisions for performance of processing
`in the telephone. As a result, ADSI generates a high traffic
`load on the telephone network since each user input is sent
`back to the service for processing. This makes ADSI unsuit-
`able for wireless networks where bandwidth is at a premium
`and “air efficiency” is one of the most sought after qualities.
`The lack of processing capability in the telephone and the
`high bandwidth requirements of ADSI have prevented it
`from being considered by the industry for implementing
`intelligent wireless devices.
`Up to now, intelligent communication devices have com-
`bined a computing module with a wireless communications
`module. However, to gain widespread acceptance, a two-
`way data communication device with processing capability
`and the ability to run a wide variety of differing user
`applications is needed. In addition, such a device should be
`comparable in size, cost, and weight to a cellular telephone.
`
`SUMMARY OF THE INVENTION
`
`According to the principles of this invention, the prior art
`limitations of combining a computer module with a wireless
`communication module have been overcome. In particular,
`a two-way data communication device of this invention,
`such as a cellular telephone, two-way pager, or telephone
`includes a client module that communicates with a server
`
`computer over a two-way data communication network. The
`principles of this invention can be used with a wide variety
`of two-way data communication networks. For example,
`two-way data communication networks for cellular tele-
`phones that may be used include a cellular digital packet
`data network as well as TDMA, CDMA, and GSM circuit
`switched data networks; and the AMPS analog cellular
`network with a modem. Similarly, for two-way pagers,
`two-way data communication networks include PACT, the
`new AT&T endorsed two way paging standard, or other
`priority two-way paging networks with data transport capa-
`bility. The two-way data communication network for a
`telephone is the public switched telephone network.
`Using the two-way communication device that includes
`the client module, a user can provide information to the
`server computer,
`retrieve information from the server
`computer, provide data to an application on the server
`computer which uses the data and provides information to
`the two-way communication device, or sends the informa-
`tion to another location. The functionally provided to the
`user of the two-way communication device is limited only
`by the applications available on a server computer that is
`accessible to the user over the two-way data communication
`network.
`
`This invention allows for the first time two-way commu-
`nications devices such as cellular telephones,
`two-way
`pagers, and telephones to become open application plat-
`forms which in turn empowers software developers to
`deliver value-added applications and services to any two-
`way communication device that incorporates the principles
`of this invention. This is a radical shift from the current
`
`situation where telephones and two-way pagers are closed,
`proprietary systems. Consequently, an even playing field is
`created for the market to invent new uses for two-way
`communication devices and for two-way communication

`networks. Any entity from corporations to individuals can
`make new applications available to the installed base of
`two-way data communication devices that
`include this
`invention without physical modification or addition to the
`two-way communication device. Years after purchase, a
`two-way communication device incorporating this invention
`will run all the applications which were developed since its
`purchase.
`Further, all these applications are available without the
`end user having to add anything or make any modification
`to the two-way communication device. Also, the applica-
`tions are independent of the two-way data communication
`network. The applications do not depend on any feature of
`the two-way data communication network. Thus, the appli-
`cations are unaffected by a change in the two-way data
`communication network.
`
`Also, the applications on the server computer are inde-
`pendent of the two-way data communication device with
`which the server computer is interacting. An application on
`the server computer can communicate with any two-way
`data communication device that includes the client module
`of this invention and a network interface module to transmit
`
`data over, and receive data from the two-way data commu-
`nication network. These two features mean that an invest-
`
`ment in developing an application is insulated from either
`advances in two-way data communication devices, or
`advances in two-way data communication network technol-
`ogy.
`
`the two-way data communication
`As indicated above,
`device of this invention utilizes a client module to transmit
`
`a message including a resource locator selected by the user
`over the two-way data communication network to a server
`on a server computer on the computer network. For
`example, the computer network can be a corporate wide area
`network, a corporate local area network, the Internet, or any
`combination of computer networks.
`The server processes the message, i.e, executes the appli-
`cation addressed by the resource locator and transmits a
`response over the two-way data communication network to
`the two-way data communication device, which stores the
`response in a memory. The client module interprets the
`response and generates a user
