Abstract: The number of messages required in networks where location services are deployed may be reduced, by providing updated location information regarding particular subscribers, or even all subscribers, to subscribed or otherwise logged applications or services upon obtaining and providing location information for a different application or service. Consequential watch services in accordance with the principles of the present invention provide location information to one or more services OTHER than or in ADDITION to the service currently requesting location information, based on subscription to a suitable service.

Abstract: Wireless carrier networks can utilize multiple MMSCs all accessed by a message sender with a message addressed to a single Internet domain, providing a single point of entry for messages into the network of MMSCs and maintaining routing information sufficient to route messages to all subscribers via the MMSC.

Abstract: A reach back secure communications terminal capable of GSM network connectivity includes a GSM fixed cellular terminal, and a single whip antenna adapted for user selectable use at any of four distinct frequency bands, e.g., 850, 900, 1800, or 1900. Immediate and secure voice, data and video connectivity is provided to multiple telecommunications networks. Integrated components simplify access to varied networks allowing deployed users to select and connect quickly to a network that best supports their present mission. Networking options include any of PSTN, PBX, GSM (or CDMA or other cell telephone standard), SAT, IP and WiFi. During secure call setup, the reach-back communications terminal exchanges public keys with a remote terminal using FNBDT signaling. Traffic encryption is performed using the NIST approved Advanced Encryption System (AES) standard (Rijndael) and a 128-bit random key (2^128 possible keys).

Abstract: A message distribution center (MDC) is interposed between content providers and a wireless carrier to subjectively examine and direct messages via SMTP based on desired rules (e.g., non-peak hours, paying subscribers only, etc.) using standard SMTP Gateway and other well-known protocols. The MDC includes a queue for each subscriber. A provider is informed through conventional SMTP protocol messages when a short message has been accepted. If the carrier has specifically disallowed service for a particular MIN, the content provider is informed through an SMTP interchange that the recipient is invalid. An MDC provides a single mechanism for interacting with subscribers of multiple carriers, regardless of each carrier's underlying infrastructure. An MDC can protect a carrier's SS7 network by intelligently throttling messages and configuring network friendly message delivery parameters. A content provider preferably communicates with the MDC using SMTP protocol messages.

Abstract: A mobile device-to-HTTP protocol gateway (MHG, or “MO Gateway”) which translates between Wireless Mobile Originated commands from an SMSC, and an application server on the Internet (i.e., a “web IP Server”). A wireless Internet gateway establishes communications with one or more relevant SMSCs using standard format SMPP commands, and the MHG utilizes HTTP protocol POST messages to post short messages originated at the mobile device to a particular URL. Return results are received by the MHG via HTTP protocol messages, translated to SMPP messages, and forwarded back to the SMSC for delivery to the mobile device. The wireless Internet Gateway communicates with the MHG using RMI protocol commands. An MHG in accordance with the principles of the present invention enables a developer to create mobile applications using standard web development tools, e.g., Java Servlets.

Abstract: An area event handler informs when a target mobile enters or leaves a network covering a pre-defined target area, and re-aims an original area event request. When the event occurs, the mobile sends a location report to an initiator of the request. A PLMN list with estimated geographic coverage areas is stored in a Home GMLC, and sent to each relevant mobile. When a mobile enters new network coverage, it uses this list for network access selection. When the Home GMLC discovers that the currently visited PLMN does not serve the original target area, it modifies the area event to the that mobile, so that the Home GMLC will be notified when the target mobile once again enters a PLMN that serves the original target area. Then, after being so notified, the Home GMLC re-sends the original area event location service request to the target mobile.

Abstract: The format of the Presence Information Data Format-Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard. PIDF-LO format, an association of geospacial location to virtual content on the Internet. A filename of virtual content is associated with geospatial location information (either a specific location, zone, or direction). The filename is inserted into a <presence . . . > section of a Presence Information Data Format-Location Object. (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based virtual content using a standard PIDF-LO format.

Abstract: A WAP-free, IETF-Specification Compliant Multimedia Message Service Center (MMSC)-Multimedia Message Service (MMS) User Agent Interface based on the Hyper Text Transfer Protocol (HTTP) is provided, as well as an all-HTTP multimedia messaging technique in general, using HTTP POST and GET techniques, between mobile stations and multimedia messaging service centers (MMSCs) for multimedia message (MM) submission and delivery.

Abstract: A technique and apparatus to provide status tracking of presence and/or location of a mobile, wireless device to a requesting entity even outside of a particular wireless system. This allows wireless service providers the ability to monitor and log changes in the status of mobile stations within and/or outside their networks. Embodiments are disclosed wherein presence and/or location information is provided to entities outside of a particular servicing wireless network using the mechanisms of call processing components of a mobile network (e.g., call setup procedures), and using standard mechanisms currently available to any appropriately conforming Mobile Switching Center (MSC) element. In one disclosed embodiment, a wireless chat tracking system is implemented which utilizes a change in mobile registration status to automatically notify a chat group system outside the wireless network of current status information activity regarding a relevant device, e.g., registration activity or inactivity timeout.

Abstract: An image tile server importantly includes an image tile cache, to support a tiled map display in a user device. Instead of the conventional user device client (e.g., an Ajax client) making image requests directly to a mapping server (MS), a display device initiates an image request of a tile server (TS), and the tile server returns the requested image. However, importantly, the tile server (TS) also retains a cached copy of the returned image for faster retrieval at a later time relating to another image request by the same or different user device.

Abstract: A message exchange network storing messages in memories of message storage entities, e.g., a mobile handset, based on the type and content of information within the message. An information service message containing supercedingly updateable information, e.g., a traffic update, is stored using a replacement method by which a previously stored message is replaced by a newly received message. All other types of messages are stored using a conventional append method. A message identifier within the message itself provides information necessary to distinguish between the aforementioned types of messages. In another embodiment, a block of message identifiers is reserved for storage of information service messages.

Abstract: An SS7-based call protocol conversion gateway that translates between circuit-switched SS7 protocols and session initiation protocol (SIP) oriented protocol, allowing an E911 call initiated over a switched network to be routed by a VoIP network. The SS7-based call protocol conversion gateway provides a PSAP with MSAG quality (street address) information about a VoIP dual mode phone user without the need for a wireless carrier to invest in building out an entire VoIP core. Thus, wireless carriers may continue signaling the way they are today, i.e., using the J-STD-036 standard for CDMA and GSM in North America, yet see benefits of a VoIP network core, i.e., provision of MSAG quality location data to a PSAP.

Abstract: A navigation system written in J2ME MIDP for a client device includes a plurality of media players each respectively comprising a buffer. A navigation program manages the state of the plurality of media players. The plurality of media players are in either one of an acquiring resources state, and a playing and de-allocating state. The use of a plurality of media players each respectively comprising a buffer overcomes the prior art in which navigation system can cut off a voice prompt because of the time-consuming tasks associated with playing a voice prompt.

By utilizing the preferred embodiment, a system administrator may be provided the capability to manage and control multiple devices, directly and indirectly, using push (server-initiated) and/or pull (client-initiated) techniques from a single location. Additionally, the preferred embodiment may be utilized to back up and securely store information on the mobile clients, identify device usage and to deliver files and databases to the mobile clients.

Abstract: An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, information relating to the specific emergency E911 call (“Call Data ID”), a guard timer, and an optional hold timer. The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected. The timestamp is reset to a current time plus a guard timer, or hold timer if desired.

Abstract: Separate IP data streams, including both voice (VoIP) and data sources, are routed over a single network data stream, encrypted by a single KIV encryption unit, and transmitted as a single packet data stream including both computer and voice data. Integration of the use of a VoIP data stream, together with data sources, and encrypted through a single serial encryption unit such as a KIV-7 enables the encryption of both voice and data using a single KIV encryption unit. After encryption by the Type 1 encryption unit (e.g., KIV-7) in a remotely deployed, secure communication system, the single encrypted data stream is encapsulated into IP packets. The IP packets are addressed to a distant IP device that removes the encapsulated, encrypted data and passes it to a similar Type 1 KIV device for decryption, and distributed to voice devices and computer devices via another voice-enabled router.
