  • Publication number: 20090093259
    Abstract: Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.

  • Publication number: 20080256641
    Abstract: Parents can desire to limit content viewable upon a mobile device and a universal integrated circuit card can be programmed to limit viewing upon the mobile device. A user completes a service request form that includes an allowable view threshold for content upon the mobile device. The request can transfer to a service provider, sometimes via a base station. A subscription manager can forward the threshold back to the mobile device and the mobile device can program the threshold upon secure storage. When content is received, it can be compared against the threshold and a determination can be made on if the content is allowable to view in light of the threshold.

  • Patent number: 5606596
    Abstract: Method and system for locating nomadic users in a personal communication services (PCS) system by utilizing two strategies for locating such users and a per-user criterion for determining which, if any, of the two strategies should be used. The method and system augment basic two-level strategies for locating users specified in IS-41 and GSM standards of PCS systems. One strategy utilizes forwarding pointers and the other strategy utilizes per-user location caching. One per-user criterion is a call-to-mobility ratio (CMR) which is the ratio of the average rate at which a user receives calls to the average rate at which the user moves. A variation of this criterion is the local CMR (LCMR) which is the ratio of the average rate at which a user receives calls from a given registration area, to the average rate at which the user moves. The method and system reduce the average time and overhead required to locate and deliver information to such nomadic users.
