Claiming priority, which is assigned to the assignee of the present application and hereby incorporated by reference.

The disclosed embodiments are directed to peer-to-peer networking for wireless devices.

Advances in technology have made personal computing devices smaller and more powerful. 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, each of which is small, light, and easily carried by the user. More specifically, portable radiotelephones also include cellular telephones that carry voice and data packets, for example, over a wireless network. In addition, many of these cellular phones are being manufactured with a relatively large increase in computational capacity, and thus are becoming equivalent to small personal computers and handheld PDAs. However, these smaller and more powerful personal computing devices are typically severely resource constrained. For example, the screen size, the amount of available memory and file system space, the amount of input / output capacity and processing capacity may each be limited by the small size of the device. Because of this severe resource constraint, it is usually desirable to maintain a limited size and amount of software applications and other information, for example, residing on such a remote personal computing device, for example a client device.

After the download of the data file is complete, wireless device 102 sends a confirmation to MMS 108 (sequence step 30). In response, the MMS 108 sends an acknowledgment to the wireless device 100 (sequence step 31) to instruct the data file transfer to the designated destination, that is, the wireless device 102.

As discussed above, data file transfer from wireless device 100 to wireless device 102 requires the use of multimedia server 108 for storage and retransmission of data files. By following this approach, additional hardware in the form of an MMS 108 computer system connected with the communication network 104 is needed to store the data file prior to transfer to the destination. In addition, both message upload steps (transmission from wireless device 100 to MMS 108) and download (transmission from MMS 108 to wireless device 102) require message sequence steps.

3 shows content 303, for example data, between two wireless devices 300, 302 connected to a communication network 304, such as a CDMA network, a GPRS network, a UMTS network, and other types of communication networks. An embodiment of routing files is shown. Peer-to-peer (PTP) application 621, that is, a set of executable instructions residing on each wireless device 300, 302 may be executed to allow content 303 exchange between wireless devices 300, 302. . As shown, content 303 delivery between wireless devices 300, 302 takes place without the need for a dedicated network server, for example MMS 108 (FIG. 1). As also shown, wireless device 302 may include content 303 (dashed lines) for delivery to wireless device 300. In addition, as will be described later, delivery of messages related to the transmission of content 303 between wireless devices 300, 302 may be accomplished by using an individual service, for example in the form of a packet data connection, from a service used to transmit content, For example, it is signaled in the form of a short service (SMS) message.

4 illustrates the operation of the embodiment of FIG. 3 in a message sequence diagram form. The originating wireless device 300 establishes a data call connection with the communication network 304 (sequence steps 41, 42, 43). While establishing a data call connection, the wireless device 300 obtains a network address 305, such as an Internet Protocol (IP) address, that addresses the wireless device on the communication network 304. After establishing the data call connection, execution of the PTP application 621 by the wireless device 300 may cause the wireless device to use the communication network 304 to send a message 60, for example an SMS message, to the destination wireless device 302. To transmit.

The message 60 includes an indication of the content 303 to be delivered from the wireless device 300 to the wireless device 302, for example using a specific message subject, subject, type or other mechanism. The message 60 also includes an address 305 of the wireless device 300 as well as a second address or sub-address 306 predetermined at the wireless device address 305, for example a port number. In an embodiment, the sub-address 306 is the setting specified for this content transfer. In another embodiment, subaddress 306 is a random value determined prior to message 60 transmission. In another embodiment, the message 60 omits the indication of the content 303 to be transmitted and includes only the address 305 to which the wireless device 302 connects, as described below. In an embodiment, the message 60 is sent using a short service, such as an SMS message.

In yet further embodiments, the message 60 content is encrypted to prevent eavesdropping on the message content. In another embodiment, the message 60 content is digitally signed to prevent tampering with the message content.

Returning to the description of the message sequence diagram of FIG. 4, after receiving the message 60, the wireless device 302 establishes a data call connection with the communication network 304 (sequence steps 45, 46, 47). In an embodiment, the data call connection with the communication network 304 uses a service other than the transmission of the message 60, for example a packet data service. After establishing the data call connection, the wireless device 302 establishes a connection such as a socket connection with the wireless device 300 at the address 305 and the sub address 306 specified in the message 60 using the communication network 304. (Sequence step 48). The term socket connection includes a communication connection between two endpoints that are uniquely identified. In an embodiment, the connection setup includes the exchange of cryptographic information, for example public and private key pairs. In each embodiment, the exchange of encryption information takes place using the service of message 60, for example an SMS message, or a content communication, for example the established data connection just described above.

After the connection is established, the PTP application 621 on each wireless device 300, 302 is executed by the wireless device to communicate using the connection, for example, a packet data service connection. As such, wireless device 302 downloads content 303 from wireless device 300 via wireless network 304 using the established connection. In an embodiment, the content 303 transmitted between the wireless devices 300, 302 is encrypted. After completion of downloading the content 303 from the wireless device 300, the wireless device 302 instructs transmission completion by sending a confirmation (sequence step 50) to the calling wireless device.

5 illustrates a high level functional block diagram of a portion 502 of the process flow of wireless device operation of the wireless device 300 according to the embodiment of FIG. 4. As shown in FIG. 5, the wireless device 300 process flow begins to operate in an idle state 504. At the beginning of the flow of the process an outgoing packet data call is placed in the network 304 (sequence step 41 in FIG. 4) and the flow transitions to a data call connection establishment step 506. In step 506 the wireless device 300 performs the sequence of steps 41-43 as described above with respect to FIG.

After establishing the data call connection, the wireless device 300 transmits the above-described message 60 to the destination wireless device 302 using the network 304, and the process flow transitions to the content transfer step 508. As described with respect to FIG. 4, in the embodiment the message 60 is transmitted using another service from the established data call connection, for example using an SMS message as opposed to packet data. In 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 executes a request processing transition 510 to handle accepting and establishing a socket connection (sequence step 48 in FIG. 4) and content. 303 is transmitted (sequence step 49 of FIG. 4).

After receipt of the confirmation from the destination wireless device 302, the process flow transitions to an idle state 504 at step 508. In other embodiments it is understood that other sequences of steps and transitions may be used to complete the embodiments described above. For example, message 60 may be sent to multiple destination wireless devices that require handling multiple requests for designated content 303. According to this embodiment, the transition from step 508 to step 504 may occur after receiving a number of requests corresponding to the number of messages 60 sent or a predetermined timeout period.

In addition, in another embodiment, the wireless device 300 transitions to the idle step 504 in step 508 and so forth, for example after a predetermined time period expires without receiving confirmation from the destination wireless device 302. . In yet further embodiments, the acknowledgment may be received from the wireless device 302 using the same service as the message 60, eg, an SMS message, instead of via a packet data service.

In addition, although the above description describes the transmission of content 303 from the originating wireless device to the destination wireless device, in one or more embodiments the transmission direction may occur in different directions and / or in both directions. That is, the destination wireless device 302 may be connected to the originating wireless device 300 to transmit content 303, and / or the wireless device 300, 302 needs an intermediate server to store the content to be transmitted. You can also send content to each other without doing so.

8 shows the operation of the second embodiment in a message sequence diagram. According to a second embodiment, a computer platform 612 to provide a failover location for storage of content 303 when the destination wireless device 302 is unavailable for file transfer by the originating wireless device 300. (FIG. 6 to be described later), for example, a desktop computer, a laptop computer and the like are used.

Outgoing wireless device 300 establishes a data call connection with communication network 304 (sequence steps 80, 81, 82). While establishing a data call connection, the wireless device 300 obtains a network address 305, for example an IP address, that addresses the wireless device on the communication network 304. After establishing a data call connection, e.g., packet data service connection, execution of the PTP application 621 by the wireless device 300 causes the wireless device to send a message 60, e.g., an SMS message as described above. Send to network 304 (not shown) intended for 302, but wireless device 302 is not connected to network 304 at this time. 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, eg, the connection 48 request of FIG. 4, the wireless device 300 Send content 303 to computer platform 612 (sequence step 85). According to the second embodiment, the computer platform 612 to which content 303 is transmitted connects with the wireless network 604 or the wired network 616 (both described below with reference to FIG. 6) and connects the network 304. It is a user specified device that can be reached by the wireless device 300 via. That is, computer platform 612 is a failover option that allows originating wireless device 300 to send the intended content 303 to destination wireless device 302. For example, computer platform 612 may be a custom desktop computer or laptop computer connected to the Internet. In addition, in the above-described embodiment, the content 303 delivered to the computer platform 612 may be encrypted.

Finally, the originating wireless device 300 is similar to the message 60 and sends a message 62 destined for the destination wireless device 302 to the network 304. The message 62 includes the address of the computer platform 612 to which the content 303 was sent, thereby enabling the destination wireless device to obtain the content 303 from the computer platform upon connection with the network 304.

9 is a message sequence diagram for retrieval by the destination wireless device 302 of the content 303 from the computer platform 612. Network 304 sends message 62 to destination wireless device 302 (sequence step 90). The message 62 includes an indication of the content 303 to be delivered from the computer platform 612 to the destination wireless device 302, for example using a particular message subject, subject, type or other mechanism. The message 62 includes an address 305 of the computer platform 612 as well as a second address predetermined at the computer platform.

After receiving the message 62 by the short 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 to communicate using the connection. As such, destination wireless device 302 downloads content 303 from computer platform 612.

Some personal computing devices use an application programming interface (API), sometimes referred to as a runtime environment and software platform, which are installed on their local computer platform and provide, for example, generalized calls to device specific resources. It is used to simplify the operation of these devices.
