A user subscription profile for a subscription-based mobile application in a wireless mobile device is established with a first mobile application service provider. The wireless device requests service for the mobile application from a second mobile application service provider. The user's subscription profile for the mobile application service is either communicated to the second mobile application service provider, or the mobile application required and allowed service information is accessed from the second mobile application service provider to enable the mobile application service to function with the second mobile application service provider as though the mobile application service were operating within the service area of the first mobile application service provider consistent with the requirements of the second mobile application service provider.

Providers of UBARR subscription-based services

A method and apparatus for determining the proper satellite communications service to be provided to a subscriber unit that may be integrated with the geographically defined service areas used in terrestrial cellular communications systems. The pre-existing geographically defined service areas are subdivided into quadrilateral tiles wherein each tile corresponds to a single service area. In addition, the tiles are mapped to a grid having a plurality of regularly spaced grid locations. A lookup table is created that references each grid location to the tiles that overlap the grid locations. The position of the subscriber unit and an approximated region of error within which the subscriber unit is likely to be located are used as input. The approximated region of error is mapped to the grid to identify the grid locations that align with the approximated region of error. Thereafter, the lookup table is accessed to identify the tiles associated with the aligning grid locations and the identified tiles are then used to identify the service area in which the subscriber unit is located so that the proper communications service may be provided. If necessary, geometrical point in polygon inclusion methods and ellipse and polygon intersection methods are used to more accurately identify the tiles of interest.

Earth tiling system for providing regional based service in a mobile satellite communication network

An apparatus for generating an on-screen television program guide. The apparatus generates a program guide including program source information and program event information for a plurality of program sources. The apparatus also generates and displays icons adjacent the program event information that represent a match between content information for a program event and selection criteria entered by a viewer.

Method and apparatus for generating television program guides utilizing

An apparatus for generating an on-screen television program guide. The apparatus generates a main menu of a program guide, which includes program source information and program event information for a plurality of program sources, and further generates navigation menus for allowing a viewer to modify the program guide. The navigation menus are generated so as to over-write only a portion of the main menu of the program guide.
