Abstract:
A mobile telephone system employs a fleet of satellites (14) and a set of gateway ground stations (10) arranged around the globe for handling communications to and from mobile communication subscriber units (12) such as mobile telephones. Signals are transmitted between a subscriber unit (10) and the nearest gateway (10) via one or more of the satellites. The gateway system is configured to process telephone call connection requests from a mobile subscriber unit (12) based upon the location of the subscriber unit. The location of the subscriber unit is employed, for example, to determine how telephone numbers are to be parsed and how to properly route emergency telephone calls to the nearest appropriate emergency service centers. Multiple location mapping schemes are employed to facilitate a determination of the location of a subscriber unit and to assist in routing emergency calls. In one implementation, each location with the service area of the system is mapped into a set of uniformly sized and shaped information cells (802). Each information cell includes pointers to data structures (806, 808) defining, among other things, the service providers that are permitted to process calls to or from that location and the nearest emergency services center. Each location is also mapped into at least one virtual service provider cell (812, 814, 816, 818, 820) which includes service provider preferences and requirements for handling a call to from that location and including a unique location identifier. A specific implementation for use with the Global System for Mobile Communication (GSM) is described.
Abstract:
A method and apparatus for operating a wireless telecommunication system utilizing code division multiple access (CDMA) over-the-air with a Global System for Mobile (GSM) communications A-interface based network is described. A CDMA radio frequency (RF) signal interface provides a bi-directional interface to a subscriber unit (50), and a Global System for Mobile (GSM) communications A-interface SS7 transport provides a bi-directional interface with GSM mobile services switching center (MSC) (52). Additionally, a transparent message transport (44) is provided over which signaling messages defined in the GSM A-interface protocol are exchanged between the GSM MSC (52) and a subscriber unit (50).
Abstract:
Methods, systems, apparatus and computer program products are described for controlling content presented on user-controlled wireless device assets and/or features, such as ringtone, wallpaper, wireless device memory and the like. In present aspects, a user-requested control state change is undertaken from a user-controlled state to an advertisement-control state. In this regard, once the user has conceded control of the wireless device asset over to an advertiser or advertisement provider, the advertiser is allowed to provide advertisements to the designated wireless device asset for a predetermined period of time. From the advertiser or advertisement provider perspective present aspects provide for advertisements to be presented on novel platforms. Additionally, by gaining control over the wireless device asset the advertisers or advertisement providers are assured that their advertisements will be executed for the duration of the control period.
Abstract:
A method of obtaining data useful for one or more network applications is described. The method is performed responsive to a triggering event, such as a dropped call, a position fix, or even expiration of a timer. A position estimate for a subscriber station is obtained responsive to the event. A record is then formed associating the position estimate for the subscriber station with an identifier of the triggering event and/or data measured or obtained responsive to the event, such as the strength of one or more pilots visible to the subscriber station. The record is either stored locally or transmitted to a remote location. In one implementation, the record is transmitted to a remote location, and stored in a database holding like records relating to other subscriber stations.
Abstract:
The mobile telephone system employs a fleet of satellites (214) and a set of gateway ground stations (210) arranged around the globe for handling communications to and from mobile communication units such as mobile telephones. Signals are transmitted between a subscriber (212) unit and the nearest gateway (210) via one or more of the satellites (214). The gateway is connected to a set of individuel service providers (216) such as local telephone systems. The individual service providers may be constrained for various reasons such as contractual or other legal constraints to handle communications only from subscriber units (212) located in certain geographical areas such as within only certain countries or portions of countries. For a mobile communication from a particular subscriber unit (212), the gateway selects (210) a service provider (216) capable of handling the communication. In one implementation, the selection is based upon the location of the subscriber unit and upon any references specified by the subscriber unit. In other implementations, the selection is based on other parameters such as the altitude, speed or velocity of the subscriber unit or the time of day or date upon which the communication is initiated.
