Description

  The disclosed embodiments relate to peer-to-via networking for wireless devices.

(Priority claim under 35 USC §119)
This patent application was filed on May 20, 2005, assigned to the assignee of the present application and expressly incorporated herein by reference, "METHODS AND APPARATUS FOR PROVIDING PEER- TO-PEER DATA NETWORKING FOR WIRELESS DEVICES Claims priority to US Provisional Application No. 60 / 683,389, entitled "

  Advances in technology have resulted in smaller and more powerful personal computing devices. For example, there are currently a variety of portable personal computing devices including wireless computing devices such as portable wireless telephones, personal digital assistants (PDAs), and paging devices that are small and lightweight and easy to carry by users. More specifically, portable wireless telephones further include cellular telephones that communicate voice and data packets, for example, over a wireless network. In addition, many such cellular telephones have been manufactured with relatively increased computing capabilities and are becoming comparable to small personal computers and handheld PDAs. However, these smaller and more powerful personal computing devices are generally severely resource limited. For example, the screen size, the amount of available memory and file system space, the amount of input / output functions and processing functions can each be limited by a small device size. Because of such strict resource limitations, it is generally desirable to maintain a limited size and amount of software applications and other information that reside on remote personal computing devices such as client devices, for example.

  FIG. 1 illustrates a wireless device 100 connected to a communication network 104 such as, for example, a code division multiple access (CDMA) network, a general packet radio service (GPRS) network, a universal mobile communication system (UMTS) network, or other network. , 102, shows a conventional approach to application execution in a wireless device for data file routing. As shown, data file communication between wireless devices 100 and 102 prior to the present embodiment is a multimedia connected to a communication network 104 to distribute data files from one wireless device to another wireless device. Requires the use of a server (MMS) 108.

Specifically, source wireless device 100 establishes a data call connection with communication network 104 (sequence steps 21, 22, and 23), and then transfers the data file to MMS 108 (sequence step 24). The data file includes an indication of the destination, such as the wireless device 102. After receiving the data file from the wireless device 100, the MMS 108 notifies the destination wireless device 102 that the data file exists on the MMS, for example by a short message service (SMS) message (sequence step 25).

  After receiving the SMS message from the MMS 108, the wireless device 102 establishes a data call connection with the communication network 104 (sequence steps 26, 27, 28). After establishing the data call connection, the wireless device 102 downloads the data file from the MMS 108 (sequence step 29). After completing the download of the data file, the wireless device 102 transmits an acknowledgment to the MMS 108 (sequence step 30). In response, the MMS 108 sends an acknowledgment to the wireless device 100 (sequence step 31), indicating the transmission of the data file to a particular destination, such as the wireless device 102.

  As described above, transmission of a data file from the wireless device 100 to the wireless device 102 requires the use of the multimedia server 108 for data file storage and retransmission. Following this approach, additional hardware in the form of an MMS 108 computer system connected to the communication network 104 is required to store the data file before sending it to the destination. Furthermore, a message sequence step is required for both uploading data (transmitting from the wireless device 100 to the MMS 108) and downloading (transmitting from the MMS 108 to the wireless device 102).

  The present invention is illustrated by way of example and not limitation in the figures of the accompanying drawings in which like reference numerals refer to like elements throughout.

  A mechanism according to an embodiment provides peer-to-peer communication of content between wireless devices using a communication network. In particular, according to this embodiment, a wireless device can use a peer-to-peer communication path to exchange content such as voice, text, video, and other multimedia content without requiring a dedicated network server. It becomes possible to set. Furthermore, the embodiment allows the wireless device to set up a communication path using different services such as a short message service and a packet data service.

  FIG. 3 illustrates content 303 such as data files between wireless devices 300 and 302 connected to a communication network 304 such as, for example, a CDMA network, a GPRS network, a UMTS network, and other types of communication networks. Fig. 4 shows an embodiment for routing. A peer-to-via (PTP) application 621, such as a set of executable instructions that reside on each wireless device 300, 302, can be executed to accomplish the exchange of content 303 between the wireless devices 300, 302. . As shown, communication of content 303 between wireless devices 300 and 302 occurs without the need for a dedicated network server such as MMS 108 (FIG. 1). Further, as illustrated, the wireless device 302 includes content 303 (dashed line) for communicating to the wireless device 300. Further, as will be described later, message communication related to the transfer of the content 303 between the wireless devices 300 and 302 is, for example, in the form of packet data connection, from a service used for transferring the content, for example, a short message service (SMS) message In form, it is signaled using individual services.

  FIG. 4 illustrates the operation of the embodiment of FIG. 3 in the form of a message sequence diagram. By activating the wireless device 300, a data call connection with the communication network 304 is established (sequence steps 41, 42, 43). During establishment of a data call connection, the wireless device 300 obtains a network address 305, such as an Internet Protocol (IP) address, for example, and specifies the address of the wireless device in the communication network 304. After establishing the data call connection, the wireless device 300 executes the PTP application 621 to cause the wireless device to send a message 60, such as an SMS message, to the destination wireless device 302 using the communication network 304 ( Sequence step 44).

  The message 60 includes displaying content 303 communicated from the wireless device 300 to the wireless device 302, for example, using a particular message title, subject matter, type, or other mechanism. The message 60 includes not only the address 305 of the wireless device 300 but also a predetermined secondary address such as a port number in the wireless device address 305, a subaddress 306, and the like. In the embodiment, the sub-address 306 is a setting value designated for such content transfer. In another embodiment, subaddress 306 is a random value determined prior to transmission of message 60. In another embodiment, message 60 omits the display of transferred content 303 and includes only address 305 to which wireless device 302 connects, as described below. In an embodiment, message 60 is sent using a short message service such as an SMS message.

  In yet a further embodiment, message 60 content is encrypted to prevent snooping of message content. In another embodiment, the message 60 content is digitally signed to prevent tampering with the message content.

  As shown back in the message sequence diagram of FIG. 4, after receiving message 60, wireless device 302 establishes a data call connection with communication network 304 (sequence steps 45, 46, 47). In an embodiment, the data call connection with the communication network 304 utilizes a different service than the transmission of the message 60, such as a packet data service. After establishing the data call connection, the wireless device 302 uses the communication network 304 to establish a connection, such as a socket connection, with the wireless device 300 at the address 305 and subaddress 306 specified in the message 60 (sequence). Step 48). The term socket connection includes a communication connection between two uniquely identified endpoints. In the embodiment, the connection setting includes exchanging encryption information such as a pair of a general key and a secret key. In each embodiment, the exchange of cryptographic information is triggered using a message 60 service, eg, an SMS message, or using content communication, eg, a data connection established as described above.

  After the connection is established, the PTP application 621 on each wireless device 300, 302 is executed by a wireless device that communicates using a connection, such as a packet data service connection. Therefore, the wireless device 302 downloads the content 303 from the wireless device 300 via the communication network 304 using the established connection. In the embodiment, the content 303 transferred between the wireless devices 300 and 302 is encrypted. After completing the download of the content 303 from the wireless device 300, the wireless device 302 transmits an acknowledgment to the originating wireless device (sequence step 50), indicating that the transfer is complete.

  FIG. 5 shows a high-level functional block diagram 502 of a portion of the operational processing flow of the wireless device 300 according to the embodiment of FIG. As shown in FIG. 5, the wireless device 300 process flow starts operating in the idle state 504. At the beginning of the process flow, a packet data call origination is made to the network 304 (sequence step 41 of FIG. 4) and the flow moves to step 506 to establish a data call connection. In step 506, the wireless device 300 performs the sequence of steps 41-43 described above with respect to FIG.

  After the data call connection is established, the wireless device 300 transmits the message 60 described above to the destination wireless device 302 using the network 304, and the process flow moves to step 508 for transferring content. As described above with respect to FIG. 4, in an embodiment, message 60 is forwarded from an established data call connection, for example, by using a different service, such as using an SMS message as opposed to packet data. During step 508, the wireless device 300 performs the sequence of steps 48 and 49 as described above with respect to FIG. Specifically, for a request coming from the destination wireless device 302, the wireless device 300 performs a request transition 510 to handle acceptance and establishment of the socket connection (sequence 48 in FIG. 4) and transfer the content 303 (FIG. 4 sequence 49).

  After receiving an acknowledgment from the destination wireless device 302, the process flow transitions from step 508 to the idle state 504. It will be appreciated that in different embodiments, different steps and sequences of transitions can be used to achieve the embodiments described above. For example, message 60 is sent to multiple destination wireless devices that request handling of multiple requests for specified content 303. According to this embodiment, the transition from step 508 to step 504 occurs either after receipt of the number of requests corresponding to the number of transmitted messages 60 or after a predetermined timeout period.

  Further, in another embodiment, the wireless device 300 transitions from step 508 to the idle state 504 without receiving an acknowledgment from the destination wireless device 302, for example, after a predetermined period of time has elapsed. In yet a further embodiment, the acknowledgment is received from the wireless device 302 using the same service as the message 60, such as an SMS message, instead of via a packet data service.

  Furthermore, although the foregoing discussion describes the transfer of content 303 from a source wireless device to a destination wireless device, in one or more embodiments, the transfer direction can be in another direction or in both directions. That is, the destination wireless device 302 connects to the source wireless device 300 and transfers the content 303 without requiring an intermediate server to store the transferred content, or the wireless devices 300 and 302 can mutually Content can be transferred.

  FIG. 8 shows the operation of the second embodiment in the form of a message sequence diagram. According to the second embodiment, for example, a computer platform 612 (FIG. 6 to be described later) such as a desktop computer or a laptop computer has a content 303 when the destination wireless device 302 cannot transfer a file with the source wireless device 300. Used to provide a failover location for storage of

  Source wireless device 300 establishes a data call connection with wireless network 304 (sequence steps 80, 81, 82). During the establishment of a data call connection, the wireless device 300 obtains a network address 305 such as an IP address and designates the address of the wireless device in the communication network 304. For example, after establishing a data call connection such as a packet data service connection, execution of the PTP application 621 by the wireless device 300 causes the wireless device to be directed to the network 304 toward the wireless device 302 (not shown). The message 60 such as the SMS message is transmitted (sequence step 83). However, the wireless device 302 is not connected to the network 304 at that time. The message 60 is as described above.

  As indicated by reference numeral 84, after a predetermined time period has elapsed without receiving a connection request from the destination wireless device 302, for example, as illustrated by connection 48 in FIG. Are transferred to the computer platform 612 (sequence step 85). According to the second embodiment, the computer platform 612 to which the content 303 is transferred is a user specified device connected to a wireless network 304 or a wired network 616 (both described below with reference to FIG. 6). Yes, and reachable by the wireless device 300 via the network 304. In other words, the computer platform 612 is a failover option in which the source wireless device 300 transfers the content 303 destined for the destination wireless device 302. For example, the computer platform 612 may be a laptop computer connected to the Internet or a user-specified desktop computer. Furthermore, in harmony with the above embodiment, the content 303 transferred to the computer platform 612 can be encrypted.

  Finally, the source wireless device 300 transmits a message 62 similar to the message 60 to the network 304 toward the destination wireless device 302. The message 62 includes the address of the computer platform 612 to which the content 303 is transferred. When connected to the network 304, the destination wireless device can acquire the content 303 from the computer platform.

  FIG. 9 shows a message sequence diagram for the acquisition of content 303 from the computer platform 612 by the destination wireless device 302. The network 304 transmits the message 62 to the destination wireless device 302 (sequence step 90). The message 62 includes displaying the content 303 communicated from the computer platform 612 to the destination wireless device 302, for example by using a particular message title, subject, type, or other mechanism. The message 62 includes the address of the computer platform 612 as well as a predetermined secondary address in the computer platform 612.

  After receiving the message 62 by the short message service, the destination wireless device 302 establishes a data call connection with the communication network 304 (sequence steps 91, 92, 93). After establishing the data call connection, the wireless device 302 establishes a connection with the computer platform 612 using the communication network 304 (sequence step 94). After the connection is established, the destination wireless device 302 executes the PTP application 621 and communicates using this connection. Then, the destination wireless device 302 downloads the content 303 from the computer platform 612.

  Some personal computing devices utilize an application programming interface (API) often referred to as a runtime environment and a software platform. APIs are installed on local computer platforms and are used to simplify the operation of these devices, for example by providing generalized calls for device specific resources. In addition, some such APIs are also known to provide software developers with the ability to generate software applications that are fully executable on such devices. In addition, some of such APIs are known to be operably placed between computing device system software and software applications, which allows software developers to require specific computing device system source code.
