Abstract:
The function of determination of location is separated from the function of gathering information based on determined location by use of a Location Object (LO) proxy between an initiating VoIP capable device and a positioning center. The LOProxy queries an appropriate location database using a location key, and injects a PIDF-LO into a routing SIP message otherwise without location. A SIP request without location is received from a VoIP capable device. The SIP request contains messages indicating the type of location generator or service needed. A location key (like a telephone number or SIP URI), in addition to the type of location generator or service needed, is included in a SIP request. A location object (LO) broker may be used between a routing SIP message and a positioning center to direct a routing SIP message to an appropriate one of a plurality of location object (LO) proxies.
Abstract:
A mobility event for a VoIP user is detected, with an estimated confidence/certainty that the VoIP user in fact moved. In response, a user is prompted to cause an update to their registration and/or location information. Notification to the VoIP user of the likely need for a location update may be implemented in the communication protocol such that an icon on the VoIP phone displays the need to the VoIP user. The icon may include a measure of the confidence/certainty of the need for a location update, e.g., similar in visual image to the bars showing coverage on a wireless phone. Mobility of the VoIP user may be detected using, e.g., (1) The VoIP user's Internet protocol (IP) address; (2) a mapping of physical to logical location; and/or (3) mapping between physical location information and physical network resources such as switches, routers, ports, access points, etc.
Abstract:
A technique to allow a server such as a location server to throttle concurrent or closely timed location requests for the position of a given wireless device such that within a certain time period preferably only one location request will be initiated to the positioning engine and the remaining closely-timed location requests will be buffered or cached. When a position for the given wireless device is returned per the outstanding location request, then the retrieved position will be used to respond to each of the buffered location requests. Thus, a plurality of location requests are satisfied with a single request to the positioning engine. By optimizing the use of cached position requests, throttling of location requests per the invention reduces network traffic significantly, increases the efficiency of a positioning server (therefore reducing business cost), and provides for an improved grade or quality of location based services in general.
Abstract:
Cell phone calls are automatically call forwarded to an in-vehicle telematics system when a driver using the cell phone is in their vehicle. Presence of the driver may be detected, e.g., by detection of a key in the ignition and presumption that the driver is in the vehicle while the key is in the ignition. The in-vehicle telematics unit signals that its driver is present. A phone number lookup is performed, e.g., by a third party database service associating cell phone number and wireless carrier with a telematics phone number of the drivers vehicle. A call forwarding request is then made between the telematics network to the relevant wireless carrier providing service to the driver's cell phone. The correct wireless carrier network is contacted, and a call forward is established to the telematics system of the driver's vehicle. When the driver leaves the vehicle, the call forwarding is terminated.
Abstract:
A tiled-map display control with a predictive caching technique that minimizes user wait time and provides at least the illusion of continuous panning, even while map tile images are being loaded. Important components of the tiled map display are its definition and cached use of map tiles, as well as the way that the map tiles are put together on a small screen. Easy, seamless, wait-free and convenient viewing of a map for a user of a wireless device provides information, e.g., mapped traffic conditions. The disclosed embodiments are techniques that have been reduced to practice in both a BREW platform, and then in a J2ME platform, and deployed for operation in major carrier wireless networks. The invention has particular applicability for use in wireless devices with typically smaller display screens requiring the need for panning, and limited bandwidth capabilities of the supporting wireless network.
Abstract:
A temporary ENUM architecture assigns a temporary ENUM at call time. For an originated communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides consistency with the specific format required by the receiving party. The TempENUM is assigned for the duration of the call or communication, or for a given amount of time thereafter. The TempENUM service gateway includes a TempENUM database, a module that assigns a suitable TempENUM at the time of call routing, and a module that handles a lookup in the TempENUM database, and maps the assigned TempENUM to a calling party identifier (CgPID). The TempENUM database stores a TempENUM from a coordinator system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication the initial caller.
Abstract:
Sensitive, Standard Telephone Equipment (STE) data is encapsulated into IP packets in a remotely deployed, secure communication system. The IP packets are addressed to a matching IP encapsulator/decapsulator device over the pubilc Internet or other IP protocol network, that then passes it to a similar STE device over an ISDN link for decryption. The present invention is embodied in a system that provides secure Voice-Over-IP (VOIP), video and data network functionality in a single, small size deployable case, to a remote user. Most importantly, the embodiment allows for the routing of bulk encrypted (i.e., secure) data over a public network, e.g., the Internet.
Abstract:
The present invention provides a '411xx' value added service to wireless users. The disclosed '411xx' service allows a mobile user who may be unfamiliar with their current geographic location to nevertheless obtain quick, accurate, and current information relating to the geographic area, e.g., different services in their current location, stores, libraries, gas stations, etc., via a mobile terminated (MT) short message system (SMS) message. In addition to the traditional '4-1-1' dialed digits, a mobile user would also dial a number (or numbers) representing a feature code for a particular service, e.g., nearby ATMs, or traffic information. Upon receiving a 411xx call, the MSC generates an ORREQ/TCAP trigger based on a translation of the requested service represented by the extra 'xx' digits. The 411xx call is terminated on the MSC after an audible whisper notice plays to the caller, e.g., "thank you for calling, your requested information will be sent momentarily".
Abstract:
A prepaid messaging solution that uses open networking standards and which supports pre-payment of enhanced Internet messaging services. The prepaid architectures and method accurately determine if a subscriber has sufficient account balance to deliver a complete short message, prior to delivery of the message. The short message may be prevented from being delivered if insufficient funds are in the subscriber's account. A prepaid tariff engine (150) is extensible over a TCP/IP network (195), and supports remote interaction with the SMSC (120) and web chat servers (170) for the purpose of applying a real-time billing charge for each message.
Abstract:
A software LBS trigger is initiated by a wireless device to request a set of proximate location information points relating to, e.g., points of interest, location tagged blogs, etc., based on the user's current location. The LBS trigger may be initiated when the user moves, and may include speed of the user to define a proximate area within which the user's device will be presented with relevant location information upon reaching. The size of the proximate area may be based on available memory in the wireless device, and/or on network bandwidth limitations. If walking, a smaller proximate area is defined, or if moving fast, the area of close proximity is larger. The location-based information points are stored locally on the user's device, and presentation to the user when the user gets closely proximate to the relevant information point.
