`POINT-TO-POINT INTERNET PROTOCOL
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`This disclosure relates to network communication
`
`5
`
`protocols, and in particular to a point-to-point.protocol
`
`for use with the Internet.
`
`2. Description of the Related Art
`
`The increased popularity of on-line services such
`
`as AMERICA ONLINE™, COMPUSERVE®, and other services such as
`
`10
`
`Internet gateways have spurred applications to provide
`
`multimedia, including video and voice clips, to online
`
`users. An example of an online voice clip application is
`
`VOICE E-MAIL FOR WINCIM and VOICE E-MAIL FOR AMERICA
`
`ONLINE™, available from Bonzi Software, as described in
`
`15
`
`"Simple Utilities Send Voice E-Mail Online", MULTIMEDIA
`
`WORLD, VOL. 2, NO. 9, August 1995, p. 52. Using such Voice
`
`E-Mail software, a user may create an audio message to be
`
`sent to a predetermined E-mail address specified by the
`
`user.
`
`20
`
`Generally, devices interfacing~e Internet and
`
`other online services may communicate with each other upon
`
`establishing respective device addresses. One type of
`
`device address is the Internet Protocol (IP) address, which
`
`acts as a pointer to the device associated with the IP
`
`-1-
`
`Samsung - Exhibit 1024 - Page 9
`
`

`
`•
`
`649-2
`
`•
`
`address. A typical device may have a Serial Line Internet
`
`Protocol or Point-to-Point Protocol (SLIP/PPP) account with
`
`a permanent IP address for receiving e-mail, voicemail, and
`
`the like over the Internet. E-mail and voicemail is
`
`5
`
`generally intended to convey text, audio, etc., with any
`
`routing information such as an IP address and routing
`
`headers generally being considered an artifact of the
`
`communication, or even gibberish to the recipient.
`
`Devices such as a host computer or server of a
`
`10
`
`company may include multiple modems for connection of users
`
`to the Internet, with a temporary IP address allocated to
`
`each user. For example, the host computer may have a
`
`c
`.. c-
`
`15
`
`general IP address "XXX.XXX.XXX...X.X.X", and each user may be
`xxx.xxx.xxx. 10
`allocated a successive IP address of Je{X XXX. XXX. lEXX. 16,
`xxx.xxx.xxx. ''
`xxx.xxx.xxx.\'d. A-
`}fXX. lElEJE. *X:x~. JE~flE. 11, XXX, XXX. XXX. XJEX. 1z , etc. Such temporary
`""'-
`IP addresses may be reassigned or recycled to the users, for
`
`;'\..
`
`example, as each user is successively connected to an
`
`outside party. For example, a host computer of a company
`
`may support a maximum of 254 IP addresses which are pooled
`
`20
`
`and shared between devices connected to the host computer.
`
`Permanent IP addresses of users and devices
`
`accessing the Internet readily support point-to-point
`
`communications of voice and video signals over the Internet.
`
`For example, realtime video teleconferencing has been
`
`25
`
`implemented using dedicated IP addresses and mechanisms
`
`-2-
`
`3
`
`Samsung - Exhibit 1024 - Page 10
`
`

`
`•
`
`•
`
`649-2
`
`known as reflectors. Due to the dynamic nature of temporary
`
`IP addresses of some devices accessing the Internet, point(cid:173)
`
`to-point communications in realtime of voice and video have
`
`been generally difficult to attain.
`
`5
`
`SUMMARY OF THE INVENTION
`
`A point-to-point Internet protocol is disclosed
`
`which exchanges Internet Protocol (IP) addresses between
`
`processing units to establish a point-to-point communication
`
`link between the processing units through the Internet.
`
`10
`
`A first point-to-point Internet protocol is
`
`disclosed which includes the steps of:
`
`(a) storing in a database a respective IP address
`
`of a set of processing units that have an on-line status
`
`with respect to the Internet;
`
`15
`
`(b) transmitting a query from a first processing
`
`unit to a connection server to determine the on-line status
`
`of a second processing unit; and
`
`(c) retrieving the IP address of the second unit
`
`from the database usin9 the connection server, in response
`
`20
`
`to the determination of a positive on-line status of the
`
`second processing unit, for establishing a point-to-point
`
`communication link between the first and second processing
`
`units through the Internet.

`
`DESCRIPTION OF THE PREFERRED EMBODIMENTS
`
`Referring now in specific detail to the drawings,
`
`15 with like reference numerals identifying similar or
`
`identical elements, as shown in FIG. 1, the present
`
`disclosure describes a point-to-point Internet protocol and
`
`system 10 for using such a protocol.
`
`In an exemplary embodiment, the system 10 includes
`
`20
`
`a first processing unit 12 for sending at least a voice
`
`signal from a first user to a second user. The first
`
`processing unit 12 includes a processor 14, a memory 16, an
`
`input device 18, and an output device 20. The output device

`••
`
`and/or wireless communication connections to the Internet.
`
`One skilled in the art would understand that the input
`
`device 18 may be implemented at least in part by the modem
`
`of the output device 20 to allow input signals from the
`
`5
`
`communication connections to be received. The second
`
`processing unit 22 may have a processor, memory, and input
`
`and output devices, including at least one modem and
`
`associated communication connections, as described above for
`
`the first processing unit 12.
`
`In an exemplary embodiment,

`
`For clarity of explanation, the illustrative
`
`embodiment'of the disclosed point-to-point Internet protocol
`
`and system 10 is presented as having individual functional
`
`10
`
`blocks, which may include functional blocks labelled as
`
`"processor" and "processing unit". The functions
`
`represented by these blocks may be provided through the use
`
`of either shared or dedicated hardware, including, but not
`
`limited to, hardware capable of executing software. For
`
`15
`
`_example, the functions of each of the processors and
`
`processing units presented herein may be provided by a
`
`shared processor or by a plurality of individual processors.
`
`Moreover, the use of the functional blocks with accompanying
`
`labels herein is not to be construed to refer exclusively to
`
`20
`
`hardware capable of executing software.
`
`Illustrative
`
`embodiments may include digital signal processor (DSP)
`
`hardware, such as the AT&T DSP16 or DSP32C, read-only memory
`
`(ROM) for storing software performing the operations
`
`discussed below, and random access memory (RAM) for storing
`
`25
`
`DSP results. Very large scale integration (VLSI) hardware

`

`
`•
`

`
`•
`
`embodiments, as well as custom VLSI circuitry in combination
`
`with a general purpose DSP circuit, may also ·be provided.
`
`Any and all of these embodiments may be deemed to fall
`
`within the meaning of the labels for the functional blocks
`
`5
`
`as used herein.
`
`The processing units 12, 22 are capable of placing
`
`calls and connecting to other processing units connected to
`
`the Internet 24, for example, via dialup SLIP/PPP lines.
`
`In
`
`an exemplary embodiment, each processing unit assigns an
`._j~-11+
`unsigned,long session number, for example, a~ bit long
`,A..
`
`10
`
`sequence in a *.ini file for each call. Each call may be
`
`assigned a successive session number in sequence, which may
`
`be used by the respective processing unit to associate the
`
`call with one of the SLIP/PPP lines, to associate a
`
`15
`
`<ConnectOK> response signal with a <ConnectRequest> signal,
`
`and to allow for multiplexing and demultiplexing of inbound
`
`and outbound conversations on conference lines.
`
`For callee (or called) processing units with fixed
`
`IP addresses, the caller (or calling} processing unit may
`
`20
`
`open a "socket", i.e. a file handle or address indicating
`
`where data is to be sent, and transmit a <Call> command to
`
`establish communication with the callee utilizing, for
`
`example, datagram services such as Internet Standard network
`
`layering as well as transport layering, which may include a
`
`-11-
`
`;;L
`
`Samsung - Exhibit 1024 - Page 19
`
`

`
`649-2
`
`Transport Control Protocol (TCP) or a User Datagram Protocol
`
`(UDP) on top of the IP. Typically, a processing unit having
`
`a-fixed IP address may maintain at least one open socket and
`
`a called processing unit waits for a <Call> command to
`
`5
`
`assign the open socket to the incoming signal.
`
`If all lines
`
`are in use, the callee processing unit sends a BUSY signal
`
`or message to the caller processing unit.
`
`As shown in FIG. 1, the disclosed point-to-point
`
`Internet protocol and system 10 operate when a callee
`
`10
`
`processing unit does not have a fixed or predetermined IP
`
`address.
`
`In the exemplary embodiment and without loss of
`
`generality, the first processing unit 12 is the caller
`
`processing unit and the second processing unit 22 is the
`
`called processing unit.
`
`15
`
`When either of processing units 12, 22 logs on to
`
`the Internet via a dial-up connection, the respective unit
`
`is provided a ~ynapm·call. allocated IP address by ~
`~ ~ .
`A connection~server
`•
`Upon the first user initiating the point-to-point
`
`20
`
`Internet protocol when the first user is logged on to the
`
`Internet 24, the first processing unit 12 automatically
`
`transmits its associated E-mail address and its dynamically
`
`allocated IP address to the connection server 26. The
`
`connection server 26 then stores these addresses in the
`
`25
`
`database 34 and timestamps the stored addresses using timer
`
`-12-

`l3
`
`Samsung - Exhibit 1024 - Page 20
`
`

`
`~·
`
`649-2
`
`•
`
`32. The first user operating the first processing unit 12
`
`is thus established in the database 34 as an active on-line
`
`party available for communication using the disclosed point-
`
`to-point Internet protocol. Similarly, a second user
`
`5
`
`operating the second processing unit 22~~pon conp ction
`
`(j._ ~
`the Internet 24 through ~connection
`·, is
`. .,
`.1\
`processed by the connection server 26 to be established in
`
`to
`
`the database 34 as an active on-line party.
`
`The connection server 26 may use the timestamps to
`
`10
`
`update the status of each processing unit; for example,
`
`after 2 hours, so that the on-line status information stored
`
`in the database 34 is relatively current. Other
`
`predetermined time periods, such as a default value of 24
`
`hours, may be configured by a systems operator.
`
`15
`
`The first user with the first processing unit 12
`
`initiates a call using, for example, a Send command and/or a
`
`command to speeddial an N™ stored number, which may be
`
`labelled [SNDJ and [SPD][NJ, respectively, by the input
`
`device 18 and/or the output device 20, such as shown in
`
`20
`
`FIGS. 5-6.
`
`In response to either the Send or speeddial
`
`commands, the first processing unit 12 retrieves from memory
`
`16 a stored E-mail address of the callee corresponding to
`
`the N™ stored number. Alternatively, the first user may
`
`directly enter the E-mail address of the callee.
`
`-13-
`
`Samsung - Exhibit 1024 - Page 21
`
`

`
`•
`
`649-2
`
`•
`
`The first processing unit 12 then sends a query,
`
`including the E-mail address of the callee, to the
`
`connection server 26. The connection server 26 then
`
`searches the database 34 to determine whether the callee is
`
`5
`
`logged-in by finding any stored information corresponding to
`
`the callee's E-mail address indicating that the callee is
`
`active and on-line.
`
`If the callee is active and on-line,
`
`the connection server 26 then performs the primary point-to(cid:173)
`
`point Internet protocol; i.e. the IP address of the callee
`
`10
`
`is retrieved from the database 34 and sent to the first
`
`processing unit 12. The first processing unit 12 may then
`
`directly establish the point-to-point Internet
`
`communications with the callee using the IP address of the
`
`callee.
`
`15
`
`If the callee is not on-line when the connection
`
`server 26 determines the callee's status, the connection
`
`server 26 sends an OFF-LINE signal or message to the first
`
`processing unit 12. The first processing unit 12 may also
`
`display a message such as "Called Party Off-Line" to the
`
`20
`
`first user.
`
`When a user logs off or goes off-line from the
`
`Internet 24, the connection server 26 updates the status of
`
`the user in the database 34; for example, by removing the
`
`user's information, or by flagging the user as being off-
`
`25
`
`line. The connection server 26 may be instructed to update
`

`
`the user's information in the database 34 by an off-line
`
`message, such as a data packet, sent automatically from the
`
`processing unit of the user prior to being disconnected from
`
`the connection server 26. Accordingly, an off-line user is
`
`5
`
`effectively disabled from making andjor receiving point-to(cid:173)
`
`point Internet communications.
`
`As shown in FIGS. 2-4, the disclosed secondary
`
`point-to-point Internet protocol may be used as an
`
`alternative to the primary point-to-point Internet protocol
`
`10
`
`described above, for example, if the connection server 26 is
`
`non-responsive, inoperative, andjor unable to perform the
`
`primary point-to-point Internet protocol, as a non(cid:173)
`
`responsive condition. Alternatively, the disclosed
`
`secondary point-to-point Internet protocol may be used
`
`15
`
`independent of the primary point-to-point Internet protocol.
`
`In the disclosed secondary point-to-point Internet protocol,
`
`the first processing unit 12 sends a <ConnectRequest>
`
`message via E-mail over the Internet 24 to the mail server
`
`28. The E-mail including the <ConnectRequest> message may
`
`20
`
`have, for example, the subject
`
`(*wp#XXXXXXXX#nnn.nnn.nnn.nnn#emailAddr]
`
`where nnn.nnn.nnn.nnn is the current (i.e. temporary or
`
`permanent) IP address of the first user, and XXXXXXXX is a
`
`session number, which may be unique and associated with the
`
`-15-
`
`Samsung - Exhibit 1024 - Page 23
`
`

`
`·-
`
`649-2
`
`request of the first user to initiate point-to-point
`
`communication with the second user.
`
`As described above, the first processing unit 12
`
`may send the <ConnectRequest> message in response to an
`
`5
`
`unsuccessful attempt to perform the primary point-to-point
`
`Internet protocol. Alternatively, the first.processing unit
`
`12 may send the <ConnectRequest> message in response to the
`
`first user initiating a SEND command or the like.
`
`After the <ConnectRequest> message via E-mail is
`
`10
`
`sent, the first processing unit 12 opens a socket and waits
`
`to detect a response from the second processing unit 22. A
`
`timeout timer, such as timer 32, may be set by the first
`
`processing unit 12, in a manner known in the art, to wait
`
`for a predetermined duration to receive a <ConnectOK>
`
`15
`
`signal. The processor 14 of the first processing unit 12
`
`may cause the output device 20 to output a Ring signal to
`
`the user, such as an audible ringing sound, about every 3
`
`seconds. For example, the processor 14 may output a *.wav
`
`file, which may be labelled RING.WAV, which is processed by
`
`20
`
`the output device 20 to output an audible ringing sound.
`
`The mail server 28 then polls the second
`
`processing unit 22, for example, every 3-5 seconds, to
`
`deliver the E-mail. Generally, the second processing unit
`
`22 checks the incoming lines., for example, at regular
`
`-16-
`
`Samsung - Exhibit 1024 - Page 24
`
`

`
`•
`
`649-2
`
`intervals to wait for and to detect incoming E-mail from the
`
`mail server 28 through the Internet 24.
`
`Typically, for sending E-mail to users having
`
`associated processing units operatively connected to a host
`
`5
`
`computer or server operating an Internet gateway, E-Mail for
`
`a specific user may be sent over the Internet 24 and
`
`directed to the permanent IP address or the SLIP/PPP account
`
`designation of the host computer, which then assigns a
`
`temporary IP address to the processing unit of the specified
`
`10
`
`user for properly routing the E-mail. The E-mail signal may
`
`include a name or other designation such as a username which
`
`identifies the specific user regardless of the processing
`
`unit assigned to the user; that is, the host computer may
`
`track and store the specific device where a specific user is
`
`15
`
`assigned or logged on, independent of the IP address system,
`
`and so the host computer may switch the E-mail signal to the
`
`device of the specific user. At that time, a temporary IP
`
`address may be generated or assigned to the specific user
`
`and device.
`
`20
`
`Upon detecting and/or receiving the incoming E-
`
`mail signal from the first processing unit 12, the second
`
`processing unit 22 may assign or may be assigned a temporary
`
`IP address. Therefore, the delivery of the E-mail through
`
`the Internet 24 provides the second processing unit 22 with
`
`-17-
`
`Samsung - Exhibit 1024 - Page 25
`
`

`
`•
`
`649-2
`
`••
`
`a session number as well as IP addresses of both the first
`
`processing unit 12 and the second processing unit 22.
`
`Point-to-point communication may then be
`
`established by the processing units 12, 22. For example,
`
`5
`
`the second processing unit 22 may process the E-mail signal
`
`to extract the <ConnectRequest> message, including the IP
`
`address of the first processing unit 12 and the session
`
`number. The second processing unit 22 may then open a
`
`socket and generate a <ConnectOK> response signal, which
`
`10
`
`includes the temporary IP address of the second processing
`
`unit 22 as well as the session number.
`
`The second processing unit 22 sends the
`
`<ConnectOK> signal directly over the Internet 24 to the IP
`
`address of the first processing unit 12 without processing
`
`15
`
`by the mail server 28, and a timeout timer of the second
`
`processing unit 22 may be set to wait and detect a <Call>
`
`signal expected f~om the first processing unit 12.
`
`Realtime point-to-point communication of audio
`
`signals over the- Internet 24, as well as video and
`
`20
`
`voicemail, may thus be established and supported without
`
`requiring permanent IP addresses to be assigned to either of
`
`the users or processing units 12, 22. For the duration of
`
`the realtime point-to~point link, the relative permanence of
`
`the current IP addresses of the processing units 12, 22 is
`
`25
`
`sufficient, whether the current IP addresses were permanent
