`ABSTRACT
`
`A handheld instant messaging terminal manages multiple
`conversation sessions across multiple instant messaging ser(cid:173)
`vices. The handheld terminal includes a handheld terminal
`housing, a data entry device integrated in the terminal hous(cid:173)
`ing, the data entry device generates textual characters and
`graphical symbols in response to actuation of the data entry
`device, a display mounted in the terminal housing to display
`textual characters and graphical symbols including the tex(cid:173)
`tual characters and graphical symbols generated by the data
`entry device, an Internet protocol communications module
`located within the handheld terminal housing to generate
`instant messaging (1M) data messages in an Internet protocol
`that include the textual characters and graphical symbols
`generated by the data entry device, a wireless transceiver
`mounted within the handheld terminal housing and coupled
`to the Internet protocol communications module to generate
`wireless data messages corresponding to the 1M data mes(cid:173)
`sages that radiate from an antenna coupled to the wireless
`transceiver, and a control module located within the housing
`and coupled to the Internet protocol communications module,
`the control module including at least one processor that
`executes an application program to implement instant mes(cid:173)
`saging and session protocols for 1M data messages commu(cid:173)
`nicated during at least one conversation session through the
`Internet protocol communications module and the wireless
`transceiver.

`INSTANT MESSAGING TERMINAL
`ADAPTED FOR WIRELESS
`COMMUNICATION ACCESS POINTS
`
`PRIORITY CLAIM
`
`This invention claims priority from co-pending u.s. patent
`application Ser. No. 1O/S46,236, which is entitled "Instant
`Messaging Terminal Adapted For Wi-FI Access Points" and
`was filed on May 14, 2004, which claims priority from u.s.
`Provisional Patent Application Ser. No. 60/532,000, which
`was filed on Dec. 24, 2003.
`
`TECHNICAL FIELD
`
`This invention relates to handheld communication termi(cid:173)
`nals and, more particularly, to handheld terminals used for
`instant messaging.
`
`BACKGROUND
`
`Instant messaging is used to describe a computer network
`service for the communication of textual messages between
`users in a real-time manner. Three major providers of instant
`messaging services are America On-Line Instant Messaging
`(AIM), Microsoft Network (MSN) Messenger, and Yahoo
`Instant Messenger. These providers enable subscribers to
`access an instant messaging service through a subscriber's
`Internet service provider (ISP), if different from the instant
`message service provider. Consequently, an instant messag(cid:173)
`ing subscriber uses a computer terminal executing an appli(cid:173)
`cation program to couple to an ISP and then access an instant
`messaging service. Once the instant messaging service is
`accessed, the user may query the service for identification of
`the "buddies" that are currently accessing the instant messag- 35
`ing service provider. "Buddies" are other subscribers to the
`instant messaging service that a subscriber has identified by
`including them in his or her buddy list. A subscriber may then
`initiate an instant messaging session with a buddy by typing
`and addressing a textual/graphical message to one of the 40
`buddies on the messaging service. When the subscriber acti(cid:173)
`vates the sending function for the message, the messaging
`service communicates the message to a buddy and activates a
`notification feature, such as an audio file, to inform the buddy
`that a message has been received through the instant messag- 45
`ing service. The buddy may then view the message, type a
`response, and send it through the messaging service. The
`conversation may continue in this manner until one of the
`parties terminates the session.
`Conversation sessions with multiple buddies at substan- 50
`tially the same time may be conducted by an instant messag(cid:173)
`ing subscriber. u.s. Pat. No. 6,539,421 describes the prob(cid:173)
`lems associated with the management and display of multiple
`conversation sessions on an instant messaging terminal.
`Among the issues that need to be addressed is the need for 55
`navigating between message windows because separate mes(cid:173)
`sage windows are used for different conversation sessions.
`Consequently, a subscriber needs to be able to identifY a
`conversation session in a window so the subscriber can
`respond appropriately to the conversation displayed in the 60
`window.
`Communication terminals for receiving textual and
`graphic messages are well-known. These terminals include
`cellular telephones, two-way pagers, personal digital assis(cid:173)
`tants (PDAs), and handheld computers, which are commonly
`known as palmtop computers. The limitations of these
`devices for instant messaging are discussed in u.s. Pat. No.
`
`2
`6,665,173. In brief, these devices are either limited in their
`textual and graphical character entry systems, unable to pro(cid:173)
`vide display access when the device is in an inactive state, or
`difficult to manipulate for data entry without platform support
`for the keyboard. Consequently, u.s. Pat. No. 6,665,173 dis(cid:173)
`closes an instant messaging terminal with an integrated key(cid:173)
`board and display that is not enclosed in a clamshell case
`when the terminal is in an inactive state.
`Wireless fidelity communication, or Wi-Fi, as it is also
`10 known, is increasing in popularity. In particular, retail estab(cid:173)
`lishments are providing Wi-Fi access points so customers can
`couple to an ISP while enjoying a beverage at the establish(cid:173)
`ment. The access point includes a radio transceiver coupled to
`a server that typically implements the S02.11 b, S02.11a, or
`15 S02.11g communication standard. Locations providing wire(cid:173)
`less access points for the Internet are commonly referred to as
`"hotspots." These hotspots are local area networks (LANs)
`and devices on such a LAN may be coupled to the Internet.
`The provision of wireless Internet access can be an important
`20 draw for an establishment, such as a coffee shop or the like.
`However, the access point must be implemented with care to
`reduce the risk that unscrupulous computer users will attempt
`Internet access through the access point for the purposes of
`web site hacking with an enhanced degree of anonymity.
`25 Design aspects considered in the implementation of a hotspot
`include the radius in which the transceiver effectively com(cid:173)
`municates and the security scheme that allows a customer to
`use an access point. Typically, the transmission power of the
`transceiver is limited to a level so the radiation pattern does
`30 not extend past the boundaries of the commercial premises to
`reduce the risk of unobserved access to the local network
`through the access point. Additionally, a security method,
`such as Wired Equivalent Privacy (WEP) or Wi-Fi Protected
`Access (WPA), is implemented by the access point compo(cid:173)
`nents to determine whether Internet access is granted through
`the access point.
`Not only is Wi-Fi used in the implementation of hotspots
`for commercial establishments but it is also used in homes as
`well. Such usage typically requires a Wi-Fi radio transceiver
`and router in a home or small office that wirelessly commu(cid:173)
`nicates with computers located in the home or office. The
`Wi-Fi router may also be used as an access point to the
`Internet. By using a Wi-Fi router, computers in the home or
`office are coupled together in a LAN without requiring cables
`to be coupled between the computers and the router for com(cid:173)
`munication purposes. The range of the Wi-Fi transceiver and
`router is important to avoid eavesdropping on electronic com(cid:173)
`munications within the home or office as well as to reduce the
`likelihood of unauthorized access to the Internet through the
`Wi-Fi router. Larger businesses may use multiple hotspots to
`provide coverage of a large building so communication
`devices within operating range of a Wi-Fi transceiver enable
`a person to remain accessible throughout the business pre(cid:173)
`mIses.
`Instant messaging is an increasingly popular service that is
`exploited at Wi-Fi hotspots and home locations. Instant mes(cid:173)
`saging subscribers may access their instant messaging ser(cid:173)
`vices through a hotspot or homelbusiness Wi-Fi router to
`conduct communication sessions with buddies. That is, a
`subscriber may access the Internet at a hotspot, home, or
`business to converse with one or more buddies through an
`instant messaging service. However, efficient utilization of
`Wi-Fi access points is encumbered by a number of disadvan(cid:173)
`tages with existing equipment. For one, most instant messag-
`65 ing is still implemented with portable computers that require
`some form of luggage for transportation. The smaller com(cid:173)
`munication devices, such as PDAs, palm computers, and two-

`into the tenninal, subsequent attempts to gain access require
`the user to remember this data and enter it at the appropriate
`time.
`Instant messaging is increasingly popular with younger
`users. These users typically prefer multiple media stimuli in
`their environment while multi-tasking. For example, they
`frequently listen to their own music while viewing videos,
`making telephone calls, and exchanging instant messages
`with buddies. When these users are situated in a Wi-Fi
`hotspot, their choice of music is limited to the music being
`played at the hotspot premises. Frequently, these users would
`prefer to have more options than those provided by the man(cid:173)
`agement of the hotspot premises.
`What is needed is an instant messaging terminal that incor(cid:173)
`porates keys for facilitating instant messaging features with(cid:173)

`

`way pagers, suffer from the textual/graphical data entry
`issues discussed in u.s. Pat. No. 6,665,173. For example, the
`keyboard especially designed for supporting instant messag(cid:173)
`ing features in u.s. Pat. No. 6,629,793 is either integrated in
`a regular sized keyboard typically used with desktop comput-
`ers or into a foldout keyboard that couples to a PDA for data
`entry. The desktop computer is not easily transportable to
`Wi-Fi hotspots and the foldout keyboard still requires a flat
`surface for support. The keyboard integrated in the instant
`messaging tenninal shown in u.s. Pat. No. 6,665,173 does 10
`not incorporate any special keys that facilitate instant mes(cid:173)
`saging. Because the instant messaging keys are separated
`from the standard keyboard section, the combination of an
`instant messaging keyboard with a standard keyboard would
`adversely impact the overall size of the instant messaging 15
`terminal. Furthennore, the communication module of that
`terminal is disclosed as being one that supports cellular radio
`communication only. Such a device would be inoperative in a
`Wi-Fi hotspot.
`Another limitation of existing instant messaging terminals 20
`is the restriction of accessing only one instant messaging
`The above limitations of previously known instant messag-
`service provider at a time. Consequently, even though a per(cid:173)
