Abstract:
A non-real time messaging system (200) for targeting messages to a subscriber unit (222) comprises a synchronized profile of where a subscriber unit should be located (a predetermined base transmission area for transmission of messages to the subscriber unit) maintained between a controller (212) and the subscriber unit. The subscriber unit detects when the subscriber unit is not within the receiving range of a predetermined base transmission area, informs the controller and the controller directs subsequent transmissions to an area identified by the subscriber unit and otherwise transmits subsequent messages to the predetermined base transmission area. The system further includes a plurality of base receivers (217) coupled to the controller for receiving transmissions from the subscriber units and allowing the controller to detect when the subscriber unit is not within the receiving range of a predetermined base transmission area.
Abstract:
A method for receiving a registration status indication at a one-way roaming selective call receiver comprises the steps of scanning (1051) a predetermined set of frequencies for an identifier(s) (1052 or 1056) broadcast on the frequencies that match identifier(s) stored at the receiver. The method provides an indication of being registered in a "home" zone (1054) if an identifier transmitted on the communication resource matches a "home" zone identifier stored in the receiver or provides for an indication of being registered in a "roaming" zone (1058) if an identifier transmitted on the frequencies matches a "roaming" zone identifier stored in the receiver or provides for an indication of not being registered (1055 or 1059) when the identifier transmitted on the frequencies do(es) not match either the "home" zone identifier or the "roaming" zone identifier stored in the receiver.
Abstract:
A memory (218) of a subscriber unit (122) is written (302) with a subscriber unit identification code (226) and an activation data package (228) including an activation home index (230), and at least one of a corresponding service provider name (232), service provider identification number (234), service provider operating frequency (236), and service provider contact information (238). The subscriber unit is programmed (304) to convey, to at least one of the user and the service provider, the subscriber unit identification code and selected portions of the activation data package and to make operational the activation home index, when the subscriber unit is in a service zone operated for the service provider and the service has not yet been activated.
