`Peer-to-Peer Mobile Data Transfer Method and Device
`
`Cross Reference to Related Applications
`
`This application is a continuation-in—part of US. patent application No. 10/817,994, filed
`
`April 4, 2004, and a continuation-in-part of US. patent application No. 10/935,342,
`
`filed
`
`September 7, 2004.
`
`Field of the Invention
`
`The present invention relates generally to data transfer techniques for mobile devices,
`
`and more specifically, a technique to establish‘data transfer directly between mobile devices.
`
`Background of the Invention
`
`Current multimedia messaging technologies for mobile devices depend upon a server
`
`that receives and prepares multimedia content to be retrieved by the recipient of the multimedia
`
`message. For example, the Multimedia Messaging Service (“MMS”) protocol utilizes a server
`
`known as a Multi Media Service Center (“MMSC") to store multimedia content in preparation for a
`
`retrieval process initiated by the recipient. Specifically, under MMS, the initiating device initiates
`
`a data connection over TCP/lP and performs an HTTP POST of an MMS Encapsulation Format
`
`10
`
`15
`
`20
`
`encoded multimedia message to the MMSC. The MMSC stores the multimedia message and
`makes it available as a dynamically generated URL link. The MMSC then generates a notification
`
`25
`
`message containing the dynamically generated URL and sends the notification message to the
`
`recipient through WAP Push over the Short Message Service (“SMS”) protocol. When the
`
`recipient receives the MMS notification message, it initiates a data connection over TCP/IP and
`
`performs an HTTP request to retrieve the MMS message containing multimedia content from the
`
`MMSC through the dynamically generated URL.
`
`The MMSC is used,
`
`in part, by the MMS protocol in order to provide a known address
`
`(e.g., a URL) that can be provided to the recipient in a text based format in order to initiate a data
`
`transfer transaction to retrieve the multimedia content. Without such a known address,
`
`the
`
`sender would be unable to transmit multimedia content to the recipient, since other pre-existing
`
`messaging technologies (e.g., SMS) only provide the capability to send limited text, and not
`
`multimedia content, directly to the recipient. As such, what is needed is a method to establish
`
`data transfer sessions directly between mobile devices, where such mobile devices are capable
`
`of directly communicating with other mobile devices through the underlying wireless technology,
`
`such that no separate multimedia server and separate retrieval notification message is needed to
`
`obtain data (e.g., multimedia content) other than text.

`

`The present invention provides a method for establishing a direct data transfer session
`between mobile devices over a digital mobile network system that supports data packet-based
`communications. Under the present invention, no separate data server need be used to provide
`a known location from which a recipient retrieves data such as multimedia content.
`Instead, a
`mobile device initiating a data transfer opens a listening port defined by an underlying data packet
`based network protocol. The initiating mobile device sends an invitation message containing the
`network address,
`including the listening port, of the initiating device to a target mobile device
`through a page-mode messaging service (e.g., text based service) supported by the digital mobile
`network system.
`The initiating mobile device further utilizes and incorporates a unique
`identification number (e.g.,
`telephone number, PIN number, etc.) associated with the target
`mobile device into the invitation message to locate and contact the target mobile device within the
`wireless mobile network. Once the initiating mobile device receives a response from the target
`mobile device at the listening port, the two mobile devices are able to establish a reliable virtual
`
`connection through the underlying data packet-based network protocol in order to transfer data
`directly between the two mobile devices.
`
`Brief Description of the Drawings

`Detailed Description of the Invention
`

`
`Figure 1 depicts one environment to deploy an embodiment of the present invention. As
`
`depicted, the underlying digital mobile network system in this environment is the Global System
`i for Mobile communications (GSM) 100 standard. Under the GSM standard, each of the mobile
`devices .105 and 110 includes a Subscriber Information Module (SIM) card that contains unique
`identification information that enables the GSM system to locate the mobile devices within the
`
`40
`
`network and route data to them. A current commercial example of a mobile device (e.g.,
`smartphone, PDA, handheld, etc.) that might be used in Figure 1 could be Research In Motion's

`(RIM) BlackBerry handheld devices, which include a QWERTY keyboard to facilitate the typing of}
`text.
`As depicted, a GSM architecture. includes the following components: base transceiver
`stations (BTS) 115 and base station controllers (BSC)
`(120A or 1208) for managing the
`transmission of radio signals between the MSC (defined below) and the mobile devices, mobile
`service-switching centers (MSC) (125A and 125B) for performing the all switching functions and
`controlling calls to and from other telephone and data systems, a home location register (HLR)
`130 for containing all the administrative, routing and location information of each subscriber
`registered in the network, visitor location registers (VLR) (135A and 1358) for containing selected
`administrative information about subscribers registered in one HLR who are roaming in a another
`HLR, and an equipment identity register (EIR) (not shown) for containing a list of all valid mobile
`equipment on the network). As depicted in Figure 1, in one architecture of a GSM network, there
`may be exist one HLR while there may exist multiple MSCs (each with a related VLR) which each
`serves a different geographic area. The MSCs also provide the interface for the GSM network to
`more traditional voice networks 170 such as the PSTN. This underlying GSM architecture
`provides radio resources management (e.g., access, paging and handover procedures, etc.),
`mobility management
`(e.g.,
`location
`updating,
`authentication and security,
`etc.),
`and
`communication management (e.g., call routing, etc.) in order to enable mobile devices in the
`GSM network to send and receive data through a variety of services,
`including the Short
`Message Service (SMS), an asynchronous bi-directional
`text messaging service for short
`alphanumeric messages (up to 160 bytes) that are transported from one mobile device to another
`mobile deviceIn a store-and-fowvard fashion.
`
`A GSM network within which the present invention may be deployed would also support a
`page-mode messaging service, such as SMS, that relies upon the underlying GSM mechanisms
`to resolve routing information in order to locate destination mobile devices. A GSM network
`supporting SMS text messaging may further include the following SMS specific components: a
`short message service center (SMSC) (140A or 140B) for storing and forwarding messages to
`and from one mobile device to another, an SMS Gateway-MSG (SMS GMSC) for receiving the
`short message from the SMSC (140A or 1408) and interrogating the destination mobile device's
`HLR 130 for routing information to determine the current location of the destination device to
`deliver the short message to the appropriate MSC (125A or 1258). The SMS GMSC is typically
`integrated with the SMSC 140.
`In a typical transmission of an SMS text message from an
`originating mobile device 105 to a receiving mobile device 110, (i) the text message is transmitted
`from the mobile 105 to the MSC 125A, (ii) the MSC 125A interrogates its VLR 135A to verify that
`the message transfer does not violate any supplementary services or restrictions,
`(iii) the MSC
`125A sends the text message to the SMSC 140A, (iv) the SMSC 140A, through the SMS GMSC,
`interrogates the receiving mobile device's HLR 130 (by accessing the 887 network) to receive
`routing information for the receiving mobile device 110, (v) the SMSC sends the text message to

`

`

`the MSC 1253 servicing receiving mobile device 110, (vi) the MSC 1253 retrieves subscriber
`
`information from the VLR 1353, and (vii) the MSC 125A transmits the text message to the
`
`receiving mobile device 110.
`
`Similar to other transactions on the GSM network, SMS text
`
`messaging utilizes telephone numbers as identifying addresses for mobile devices and as such,
`
`utilizes the SS7 network signaling system through which cellular service providers share
`
`information from the HLR with other service providers. As depicted in Figure 1, SS7 based
`
`signaling communication is represented by the broken lines.
`
`In contrast, the solid lines in Figure
`
`1 represent data or voice based communications.
`
`In addition to a page-mode messaging service such as SMS, a GSM network withift
`
`which the present
`
`invention may be deployed would also support a data packet based
`
`communications service, such as the General Packet Radio Service (GPRS),
`
`that enables
`
`TCP/IP transmission protocol based communications between mobile devices within the network.
`
`As depicted in Figure 1, a core GPRS network exists in parallel
`
`to the existing GSM core
`
`network. The BSC 120 may direct voice traffic through the MSC (125A or 1253) to the GSM
`
`network and data traffic through the Serving GPRS Support Note (SGSN) (145A or 1453) to the
`
`GPRS network. Such communication between the BSC (125A or 1253) and the SGSN (145A or
`
`1453) may be, for example, based upon the IP network protocol communication 155. As such,
`
`.
`
`GPRS signaling and data traffic do not flow through the core GSM network.
`
`Instead, the core
`
`GSM network is used by GPRS only for table look-up in the HLR 130 and VLR (135A or 1353) to
`obtain routing, location and other subscriber information in order to handle user mobility. The
`SGSN (145A or 1453) serves as a "packet-switched MSC," delivering data packets to mobile
`
`devices in its service area. The Gateway GPRS Support Note (GGSN)
`
`(150A or 1503)
`
`communicates with the SGSN (145A or 1453) through an IP based GPRS backbone 160 and
`
`serves as an interface to other external IP networks 165 such as the Internet and other mobile
`
`10
`
`15
`
`20
`
`25
`
`service providers' GPRS services.
`
`In order to provide direct data transfer capabilities between mobile devices, an initiating
`
`mobile device must have knowledge of the IP address (and possibly, a port) of the target device
`in order to establish a direct data transfer. Current mobile multimedia messaging solutions, such
`
`as MMS do not provide direct data transfer capabilities because the initiating mobile device is not
`
`able to obtain the receiving mobile device's IP address.
`
`In essence, servers such as the MMSC
`
`that are used in current multimedia messaging solutions serve as a forwarding agent between the
`
`two mobile devices that are unable to determine the other devices IP address.’
`
`In contrast,
`
`in accordance with the present invention, a multimedia server such as the
`
`MMSC can be eliminated on a mobile network environment such as that depicted on Figure 1.
`
`Through the use of a page-mode messaging service, such as SMS, which transmits messages to
`
`mobile devices based upon their telephone numbers, an initiating mobile device can transmit its
`
`IP address (and a listening port) in an invitation message to a target mobile device through the
`
`30
`
`35
`
`Apple Inc.
`Ex. 1023 - Page 6
`
`Apple Inc.
`Ex. 1023 - Page 6
`
`

`

`target device's telephone number. Once the target device receives the invitation message, it is
`able to contact the initiating mobile device through the received IP address and the two devices
`can establish a reliable virtual connection, such as a TCP connection, for reliable data transfer
`
`session. Figure 2 depicts a flow chart depicting the steps taken by an initiating and target mobile
`
`device to establish a direct data transfer session in accordance with the present invention.
`
`Initially, the initiating mobile device opens a TCP port to listen for communications from the target
`
`mobile device 210. The target mobile device has also similarly opened an SMS listening port to
`
`receive invitation SMS text messages at the specified SMS port 220. The initiating mobile device
`
`then transmits its IP address (and TCP port) in an invitation SMS text message to the telephone
`
`10
`
`phone number and a specified SMS port of the target mobile device 230. The target mobile
`device receives the SMS text message containing the initiating mobile device's IP address (and
`
`TCP port) at the specified SMS port 240. The target mobile device extracts the IP address and
`
`TCP port from the SMS text message and opens its own TCP port 250. The target mobile device
`
`then transmits a request to establish a TCP connection to the initiating mobile device's IP address
`
`.15
`
`and TCP port 260. The initiating mobile device receives this request 270 and a TCP connection
`
`is established between the IP addresses and TCP ports of the initiating and listening mobile
`
`devices and these devices are able to engage in a data transfer session over a reliable virtual
`
`.
`
`connection 280.
`
`Alternative, Figure 3 depicts a flow chart for an alternative embodiment depicting steps to
`establish a direct data transfer session in accordance with the present invention.

`initiating mobile device opens a TCP port to listen for communications from the target mobile
`
`device 310. The initiating mobile device,
`
`through its supporting telephone company,
`
`then
`
`embeds its IP address (and TCP port) in the telephony ringing signal that is transmitted to the
`
`25
`
`30
`
`target mobile device 320. For example and without limitation, the telephone company may use a
`
`frequency shift keyed (FSK) signal to embed the lPiaddress (and TCP port) into the telephony
`signal, similar to the traditional techniques used to embed other special service information, such
`as a caller ID,
`in the traditional
`telephony context. The target mobile device receives the
`telephony ringing signal from the initiating mobile device 330. The target mobile device extracts
`the IP address and TCP port from the telephone ringing signal and opens it's own TCP port 340.
`
`The target mobile device than transmits a request to establish a TCP connection to the initiating
`mobile device’s IP address and TCP port 350. The initiating mobile device receives this request
`360 and a TCP connection is established between the IP addresses and TCP ports of the
`
`initiating and listening mobile devices and these devices are able to engage in a direct data
`
`transfer session over a reliable virtual connection 370.
`
`35
`
`While the foregoing detailed description has described the present invention using SMS,
`
`GSM, GPRS, and TCP/IP, other similar services and protocols may be used in a variety of similar
`
`environments in which the present invention may be implemented. For example and without

`
`

`

`limitation, rather than using SMS to transmit an IP address (and port) from the initiating mobile
`
`device to the listening mobile device through the devices’ telephone numbers, an alternative
`
`embodiment of the present invention might use a PlN-to-PIN messaging technology (as, for
`
`example, offered in RIM's Blackberry handheld devices) to transmit the IP address (and port)
`
`through unique PIN numbers associated with the mobile devices, or an alternative paging
`
`protocol using telephone numbers. Similarly, rather than using FSK to embed the IP address
`
`(and port) into the telephony ringing signal, an alternative embodiment of the present invention
`
`might use a Duel Tone Multi-Frequency (DTMF) transmission to embed the IP address and port.
`
`Furthermore,
`
`the present
`
`invention contemplates that
`
`the actual protocol used during an
`
`established IM session may also vary depending upon the preference of the implementation. For
`
`example and without limitation, Message Session Relay Protocol (MSRP) or any proprietary
`
`based protocol may be used during the lM session that is established in accordance with the
`
`present invention. Thus, various modifications, additions and substitutions and the like can be
`
`made without departing from the spirit of the invention and these are therefore considered to be
`
`within the scope of the invention as defined in the following claims.
