A system for providing coordinate-based location information may include first, second and third wireless location transmitters. The wireless location transmitters may be located at fixed positions within an enclosure, such as a building. The wireless locations transmitters may each be programmed with a respective coordinate-based location, which the wireless location transmitters can in turn wirelessly transmit to a wireless device. The wireless device can then use the three respective coordinated-based locations of the wireless location transmitters to determine a coordinate-based location for the wireless device.

A telephony interface system has a controller and multiple communication interfaces to provide voice-over-packet (VoP) telephone service with PSTN telephone service as backup. The telephony interface system has a communication interface for at least one telephony device, a communication interface for the PSTN, and a communication interface for a packet-switched network. To originate a call, the telephony interface system connects the telephony device to the PSTN if the dialed digits for the call correspond to a predetermined telephone number or numbers, such as 911. Otherwise, the telephone interface system connects the telephony device to the packet-switched network.

A system is provided comprising a computer system, a configuration database, and a dynamic network interfaces application that receives a message from a network access component containing a request to authenticate a client device accessing a network service, determines that a policy requires the client device to be associated with a virtual local area network to access the network service, and authenticates the client device for association with the virtual local area network. The dynamic network interfaces application also searches the configuration database for configuration information to provision the virtual local area network, assigns the configuration information to the client device, the network access component, and a firewall component, and sends a reply containing the configuration information to the network access component and the firewall component in response to the request, wherein the configuration information comprises settings to provision the virtual local area network.

A dynamic network policies system based on device classification is provided. The system comprises a computer system, a configuration database, and a dynamic network policies application based on device classification that receives a message from a virtual local area network access component containing a device identity certificate. The application parses the device identity certificate to discover a device classification, references the configuration database to determine a network policy associated with the device classification, and associates the network policy with a virtual local area network definition. The application also sends a reply containing the virtual local area network definition to the virtual local area network access component in response to the request, wherein access to network services is made available by association with a virtual local area network, and wherein association with a virtual local network is specific to the device classification and the network policy.

A media player is provided. The media player comprises a communications interface, a memory store containing a plurality of personalized advertisements, and a media playback component. The targeted advertisements are refreshed by receiving updates from the communications interface during some of the intervals when the media player is connected to a network. The targeted advertisements are indexed by a plurality of characteristics, the first characteristic being a creation date of the targeted advertisements. The media playback component is configured to play a media content, wherein the media content is stored separately from the targeted advertisements, and to play one of the targeted advertisements in the memory store selected based on the characteristics of the one of the targeted advertisements.

A method of monitoring a portable electronic device electronically is provided. The method comprises receiving a first radio signal, the first radio signal emitted by the electronically monitored portable electronic device and determining a first received signal strength of the first radio signal. The method also comprises receiving a second radio signal, the second radio signal emitted by the electronically monitored portable electronic device, the second radio signal received after the first radio signal. The method also comprises determining a second received signal strength of the second radio signal, comparing the second received signal strength to the first received signal strength, and alerting when a result of the comparing exceeds a threshold.
摘要:
Each wireless access point in a wireless local area network (WLAN) is allocated a set of one or more identifiers. A correlation database stores information that relates the geographic location of each wireless access point and the identifiers allocated to it. When a mobile node associated with a wireless access point in the WLAN originates a 9-1-1 or other emergency call, one of the wireless access point's identifiers is included in the call origination request. By querying the correlation database, the wireless access point's geographic location may be determined from the identifier. When a public safety answering point (PSAP) answers the mobile node's call, the PSAP may obtain the geographic location of the wireless access point with which the mobile node is associated. This location information could be pushed to the PSAP, or the PSAP could obtain the location information by querying the correlation database.

A multi-mode mobile station includes a first interface for wireless communication with a wireless local area network (WLAN) and a second interface for wireless communication with a wireless wide area network (WWAN). A call control system routes all calls to and from the multi-mode mobile station through a media gateway that serves as an anchor point for handoffs between the WLAN and WWAN. For example, while involved in a call that has a WLAN call leg from the media gateway, the multi-mode mobile transmits a handoff request. The call control system then establishes a WWAN call leg from the media gateway, and the multi-mode mobile station stores in a buffer any media received via the WWAN call leg. The call control system subsequently transmits a handoff instruction to the multi-mode mobile station. In response, the multi-mode mobile station plays out the stored media and drops the WLAN call leg.

A computer implemented method for user interface navigation engine is provided. A number of items to display is determined based on an interface screen parameter. The number of items is displayed based on the numerical position on a list selected for display. A displayed item is highlighted, wherein a position of the highlighted displayed item on a screen indicates a position relation of the displayed number of items to the count of items in the list.
摘要:
A method to translate between Public Switched Telephone Network (PSTN) numbers and Voice over Internet Protocol (VoIP) addresses without performing an address translation database lookup. A network gateway receives and translates a first endpoint identifier associated with a destination client device to a second endpoint identifier associated with the destination client device. The first endpoint identifier is either a PSTN number or a VoIP address comprising at least the PSTN number and a predefined suffix and the second endpoint identifier is the other of the PSTN number and the VoIP address. The network gateway translates the first endpoint identifier to the second endpoint identifier without performing an address translation database lookup, by either adding the predefined suffix to or removing the predefined suffix from the first endpoint identifier. The network gateway generates and transmits a second session initiation message containing the second endpoint identifier to facilitate establishment of the session.
