A system and related techniques automatically analyze Web search and other activity, to generate locality-selected results based on not just the user's location, but also the business or other content provider's location and the degree of local intent in the user's query. The locality or region to the user may be identified, for instance, by the presence of geographic clues or indicators in the general content of the Web site, for instance, the presence of ZIP codes, telephone numbers, town names or other semantic or other indicators which have some geographic connotation in search terms, key words or other query or semantic inputs. The user's degree of local intent may be automatically analyzed as well, for instance by the presence of terms such as “car repair” or “pizza restaurant” which may suggest the user intends to locate local goods, services or providers. The search service may then access a content database to identify ads or other media or content which match or correspond to the detected locality or region, such as ads for local restaurants, car dealerships, physicians or other services or products, and which correspond in location, working radius and degree of localness to the user's query. Because the delivery of localized search results according to the invention is specifically filtered for user-driven local intent, advertisements and other media or content may be delivered which better match the user's search objectives.

A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.

The present invention provides a method for preventing a driver of a motor vehicle from using a cellular telephone while the motor vehicle is in motion. The invention comprises a step of determining a position of the gear shift lever in such motor vehicle and generating a first signal when the position of such gear shift lever is moved to and remains in one of drive, overdrive, second, low, and reverse. Another step involves transmitting such signal generated in a previous step to a means disposed in a predetermined location on such motor vehicle for generating a reverse phase signal. Another step involves generating such reverse phase signal when such first signal is received by such means. A next step is transmitting such reverse phase signal for a predetermined radius from such predetermined location. A last step is preventing any cellular telephone transmission within such predetermined radius when such reversed phase frequency signal is being transmitted.

A system and method is disclosed for forwarding location dependent messages from a message sender's mobile cellular device to an intended recipient's mobile cellular device. The method is principally practiced in a communication network comprising a plurality of mobile cellular devices having location determining capabilities such as triangulation and GPS. In an embodiment, the message sender identifies an intended message recipient and selects a geographic location and corresponding radius of circumference defining geographic pre-conditions for transmitting the location dependent message to the intended message recipient. The message is first transmitted to a central server which periodically monitors the geographic location of the intended recipient in real time or near real-time to determine if the intended recipient enters within the radius of circumference of the geographic location selected by the message sender. The message is transmitted from the central server when it is determined that the intended recipient has satisfied the geographic pre-conditions. In other embodiments, a cellular mobile device user is alerted when one or more contacts of the user arrives within a certain geographic proximity of the user.

Accordingly, viewers can view images projected on the screen corresponding to 5-50 times the brightness of conventional cases. Central speakers are arranged at the focal point of the spherical screen, so that viewers perceive the sound effect as coming directly from the spherical screen. This visual and audio system can be effectively used in theaters for stereoscopic movies, theaters for high resolution images, and theaters for viewing of images at a higher brightness such as theaters for sports broadcasts, and restaurant theaters, etc.

The present invention is directed to systems for and methods of using dual mode handsets or softphone client for voice, sms, and data services.

The SIP REGISTER messages are translated into corresponding MAP registration (or RADIUS message) and authentication commands, allowing system to contact the HPLMN HLR (or home AAA) associated with the mobile device to authenticate the mobile device and register it on a VLR of a visiting network. MAP responses (or RADIUS response) are translated to corresponding SIP commands that are forwarded to the mobile device, thereby completing the connection set up.

In a General Packet Radio Service (GPRS) network, a system and method of dynamically allocating an Internet Protocol (IP) address to a mobile terminal (MT) operating in the network. A Gateway GPRS Service Node (GGSN) requests IP addresses over the Gi interface from a Radius server in an IP-based network. A Conditional PDP Address (CPA) parameter is stored in the MT's Home Location Register (HLR) as part of the user subscriber data, and is passed to the GGSN during the GPRS Attach procedure. The CPA parameter indicates whether the subscriber is entitled to a backup IP address in case of failure to obtain one over the Gi interface, and whether the MT is a user of a real-time application. A timer in the GGSN sets a maximum time period (Ti) that the GGSN will wait for a response from the server, and a counter (Ni) sets the maximum number of requests that are sent. A Network Access Server (NAS) in the GGSN sends a request for an IP address from the GGSN to the server, and determines whether Ti expires without receiving a response from the server. If no response is received, the GGSN allocates an IP address. A public IP address is allocated only if the MT is a user of a real-time application. Otherwise, a private IP address is allocated.

A point-of-interest mapping search system that combines inexact string searches with a proximity search to provide an extremely high probability of return of a set of search results in an initial search response that are useful to the user. Relevance of any particular point-of-interest item in a combined inexact string/proximity is dependent on both (1) a quality of the name match; and (2) a proximity to the starting location (or other relevant search center point) of the POI search. The inexact string name/proximity search is performed efficiently by iteratively expanding a search radius around a given location, searching concentric circles of proximity until a specified target number of relevant results have been found. It is the combination of the use of a combined inexact string match together with a proximity search performed against a database of geo-referenced business names that provides advantageous results.

A system and method for cellular telephone based electronic access control (EAC) of secured portals is depicted. The EAC system determines whether access to any particular secured portal is to be granted to a user based on the relative geographic positions of the secured portal and the user's cellular telephone.
