Abstract: A user runs an album application on a digital device to generate a digital album and share the album with others. The album application creates a message with a first copy of the album and a link to a second copy of the album on a website hosted by a photo sharing provider. The first copy of the album is a small file because it contains low resolution versions of the photos and it uses a compact file format (e.g., Adobe Flash or HTML5). After the message is sent, the album application uploads high resolution versions of the photos to the photo sharing provider. A recipient of the message may view the first copy of the album in the message or click on the link to access the second copy of the album from the website hosted by the photo sharing provider. The recipient may order prints of the album from the photo sharing provider or a print provider working with the photo sharing provider. The recipient may further share the album by forwarding the message or the link to others.

Abstract: Provided are a method and a device of a host with IPv4 application for performing communication. The method of the host with IPv4 application for performing data communication includes the following steps: the IPv4 application generates an IPv4 packet sent to a communication end; when confirming the type of the network the host is located in is an IPv6 network, the host transforms the IPv4 packet head of the IPv4 packet to an IPv6 packet header, and sends it to the communication end via the IPv6 network. With this invention, it can be accomplished that according to the type of the network the host is located in, the host with IPv4 application communicates with a communication end; the processing load of the system is lightened; the probability that invalidation occurs at a single node is reduced; the smooth migration and transition from original IPv4 application to IPv6 system are facilitated.

Abstract: A method is provided so mobile devices can communicate through their wireless data services to a public computer network, which are normally deactivated when not in use. A first device calls a second device over a wireless voice service. The first device activates its wireless data service and sends a request to communicate with the second device to a server on the public computer network. Without answering the voice call, the second device determines an ID of the first device. The second device then activates its wireless data service and sends a query to the server to determine if the first device desires to communicate over the public computer network. The server responds to the request and the query by setting up a network connection between the first and the second device over the public computer network so they can exchange data packets.

Abstract: A server including: a communication unit for wirelessly communicating with a mobile terminal through one of wireless network gateways; and a processing unit for receiving registration request information from the mobile terminal through the communication unit, executing handoff from one wireless interface to another wireless interface and sending a signal instructing the termination of wireless connection generated by the processing unit to the wireless network gateway through the communication unit to release wireless connection before handoff between the server and the access point when the registration request information indicates the termination of the current wireless connection.

Abstract: The objective of the invention is to provide a mobile communication control method and mobile communication system in which mobile IPv6 and SIP are integrated by a core network of 3GPP2. In the mobile communication system, the mobile node MN executes a registration procedure for a Care-of-Address acquired in a visited network by the communication between the mobile node and a home agent server HA, executes a registration procedure for the Care-of-Address by the communication between the mobile node and an SIP server, and executes a communication procedure for session establishment by the communication between the mobile node MN and a correspondent node not through the home agent server but through the SIP server.

Second method for sharing telephone resources includes a first VoIP device joining with a group of VoIP devices connected to an IP network to share their telephone resources, receiving from a caller a telephone number to call a device, connecting to a second VoIP device from the group over the IP network, transmitting the telephone number to the second VoIP device so the second VoIP device connects to the device through a telephone system, and transmitting to and receiving from the second VoIP device voice signals between the caller and a recipient at the device.

Abstract: A method for an authentication server to authenticate Voice over Internet Protocol (VoIP) devices includes receiving a request from a unverified VoIP device to verify its global telephone number over a computer network, searching for verified VoIP devices that have authenticated identities and caller ID service, and providing the telephone numbers of the verified VoIP devices to the unverified VoIP device, wherein the unverified VoIP device calls the verified VoIP devices and the verified VoIP devices detect telephone numbers of the unverified VoIP device. The method further comprises receiving the detected telephone numbers from the verified VoIP devices and determining if the detected telephone numbers match a telephone number provided by the unverified VoIP device, wherein the unverified VoIP device becomes verified if the telephone numbers match the telephone number provided by the VoIP device.

Abstract: A first video stream is analyzed for generating consecutive video segments. Each video segment indicates a specific scene in the video stream. A first intra frame is added at a start of each of the video segments, and second intra frames are inserted each fixed interval of video frames from the start of each of the video segments for spacing two consecutive second intra frames by the fixed interval of video frames in each of the video segments.

Abstract: A first device in a first local area network (LAN) searches for a first Universal Plug and Play (UPnP) enabled router with a first public network address. If found, the first device obtains the first public network address of the first router and configures a first mapping table of the first router to associate several ports number to the first device. These actions may be repeated by a second device in a second LAN for a second UPnP enabled router with a second public network address and several ports number. The two devices then connect through a secondary communication channel (e.g., a telephone network) to exchange networking information. The two devices then use the networking information to establish a computer network connection over a public computer network that couples the first and the second LANs for point-to-point communication.

Abstract: A method is provided to communicate regional services to a telephone gateway device over a public computer network. The method includes a distribution server sending a list of entities offering a desired service in a desired region to the telephone gateway device. The list includes probability parameters that the telephone gateway device uses in a lottery to arrange the order in which the entities are displayed. A service server adjusts the probability parameters based on the amount of information about the respective businesses accessed by the consumers and the price the respective businesses pay for the access.

Abstract: A first device uses a PSTN to send its public IP address to a second device to setup point-to-point communication over the Internet. The first device calls the second device over the PSTN. In one embodiment, the second device answers the call and the first device transmits its public IP address over the connected call to the second device. In another embodiment, the second device does not answer and the PSTN transmits the public IP address as signals in several intervals between telephone rings to the second device. The second device then sends a connection request to the first device over the Internet using the IP address. Once the connection over the Internet has been established, the first and the second devices point-to-point exchange data packets carrying text, voice, video, or data communications between their users.
