    摘要: A communication system (100) for providing messages to a pager (140) includes a first sub-system (105) having a home terminal (125) for normally transmitting the messages to the pager (140) in a first geographic region. The communication system (100) also includes a second sub-system (115) having a local terminal (135) for transmitting the messages to the pager (140) when the pager (140) has roamed into a second geographic region. The local terminal (135) of the second sub-system (115) includes a data port (505) for receiving a message for transmission to the pager (140), a controller (510) for determining that the pager is roaming, and a requester (580) for automatically transmitting a request for a subscriber record associated with the pager (140) from the first sub-system (105) in response to determining that the pager (140) is roaming.

    摘要: A method carried out at a transmitter (800), of limiting visual information that can be stored or transmitted captures a visual image (608). Whenever a control signal is detected (612) at the transmitter (800), at least a portion of the visual image is obscured (616) to produce an obscured visual image. This obscured image is then stored and/or transmitted (620). The image can be obscured by any number of techniques including replacement of the image with a substitute (718), blurring, distorting or reducing the resolution of the background (738), substitution of backgrounds (762) or removal of the background (778).

    摘要: A technique is used in a simulcast radio communication system (200) for providing improved local time information. The technique includes, in a fixed portion (300) of the simulcast radio communication system (200), alternatively transmitting in a radio signal a first local time and a second local time in a predetermined protocol position that occurs periodically in a signaling protocol, wherein the first local time and second local time differ by a time zone interval. A radio (500) that receives the radio signal presents local time to a user in manner that indicates the first and second local times.

    摘要: A subscriber's PMU (Personal Messaging Unit) (14) determines when the number of incoming messages is likely to be excessive by counting the incoming messages and comparing their number and rate of receipt to stored thresholds. The subscriber is alerted when an excess is detected, and he is given options such as: routing future messages to himself via alternate and less expensive communication links (34,38), or terminating messages sent to one of his PMU's addresses that has been receiving messages at a high rate. Similar control can be effected at the PMU's base station (12).

    摘要: A method and apparatus select a receive frequency of a receiver (400) in a system having coverage areas divided into zones. A primary scan list is stored in the receiver (400) and contains coverage area identification parameters. The list is initially ordered from a most frequented coverage area at the top to a least frequented coverage area at the bottom. The parameters can include a coverage area identifier and a zone identifier, and at least one corresponding frequency identifier. A frequency identifier is chosen (604) from the top of the list and the receiver (400) is tuned to the receive frequency identified thereby. Baud rate detection is performed (608) and, in response to finding a predetermined baud rate, a received coverage area identifier and/or a received zone identifier is decoded (612). If the received identifier matches a corresponding parameter stored in the receiver, the receiver (400) is locked (904) to a signal on the receive frequency.
