Abstract: A messaging system capable of transmitting messages to receivers which roam between coverage areas. In one configuration, a coverage area (600) is divided into a plurality of zones (605, 610, 615). A single simulcast system identification (SSID) number is assigned which consists of a local identification number which identifies the coverage area (600), a zone identifier which identifies a zone (610) within the coverage area, traffic splitting flags and a frequency. For larger roaming areas, a network is defined as consisting of a plurality of service areas and is identified by network identification information (NID). NID information and/or SSID information along with a priority value is stored in a receiver according to desired coverage and like information is transmitted in the corresponding zone or service area and the roaming pager operates on the frequency having the NID or SSID having the highest priority.

Abstract: A transmitting management apparatus transmits information having an identification number corresponding to a portable information terminal to which information is to be delivered and/or having a sorting code identifying the information. The portable information terminal receiving the transmitted information selectively acquires and stores proper information by referring to the identification number and/or the sorting code of the received information, and displays the proper information on a display means.

Abstract: Communication of information including data between a remote computer and a vehicle is managed and facilitated using an apparatus compatible with standardized network communication links. In one embodiment, the standardized network communication links include the Internet and a controller area network used in vehicles. The apparatus preferably includes a controller contained in the vehicle. The controller is comprised of a number of hardware and software elements including a processor. A TCP/IP stack is part of the controller for providing the necessary control in checking for communicating information, such as requests and data, over the Internet. A web server communicates with the TCP/IP stack for servicing information related requests in http format including obtaining or sending information in operative communication with the TCP/IP stack.

Abstract: A radio selective call receiver with display includes, a storage device for storing at least received messages, a display device for displaying the received messages, an adder for associating the retrieval attribute to the received messages, and a retrieving mechanism for retrieving the received messages on the basis of the retrieval attribute. The retrieval attribute can be selectively added at any time of reading out a received message or when displaying the message at a time of reception. Further, an added retrieval attribute can be selectively changeable or deletable any time after reception of the message, and a received message, not requiring retrieval, may have no retrieval attribute set, thereby to exclude the received message from retrieval messages.

Abstract: A paging controller (10) schedules the transmission of pages of different protocol types, dynamically, taking into account both the airtime efficiency of transmitting a page of a particular protocol type and the fairness of transmitting pages of that protocol type. The paging controller (10) determines the efficiency of transmitting stored pages for each protocol type based upon the number of code words stored for the pages of the protocol type in a paging queue (27-30) and based upon the delay, if any, that is expected to be encountered in changing to the protocol type. The paging controller (10) determines the fairness of transmitting pages of a particular protocol type based upon the age of the pages of the protocol type that are stored in the paging queue (27-30).

Abstract: A satellite-based, world-wide cellular messaging system (5) transmits paging messages to pagers (2) via multiple beams. A pager (2) monitors multiple beams, recording the schedules for each beam, and by combining the schedules for multiple beams, ultimately determines which frames in the message groups to monitor for messages. As propagation characteristics degrade, an adaptive method refines the criteria for including frames into a monitoring schedule.

Abstract: A method, and associated apparatus, for providing a wireless communication station with a dynamically-assigned address which provides a temporary address to route data to the wireless communication station. A temporary address is assigned to the wireless communication station to permit data, such as packet data, to be communicated between the wireless communication station and a correspondent host. Once communication with the wireless communication station is terminated, the temporary address can be reassigned and reused pursuant to subsequent communications with another wireless communication station.

Abstract: A valid bit generator of a base station generates a valid bit to be disposed at or near the top of a message to be transmitted. The valid bit is set to be inactive if the message can be ignored, or active if the message cannot be ignored. Upon reception of this message, a valid bit detector at each terminal station judges whether the valid bit of the received message is inactive or active. If the valid bit is inactive, a message analyzing process is immediately stopped, whereas if it is active, the message is received and analyzed to the end thereof.

Abstract: A paging receiver receives a message data including an overhead and a body data. The paging receiver has a first memory with multiple memory slots for holding the body data from multiple message data, and a second memory for holding information about the current storage methods for memory slots of the first memory. The overhead of the message data specifies a memory slot number for storing the body data, and also specifies a method of storing the body data, which may be storage by replacement of current contents, storage by combination with current contents, etc. A controller of the paging receiver selects the storage method from the second memory if the overhead does not specify the method of storing the body data, but uses the method specified in the overhead when present. The body data of the message data is placed in the specified slot of the first memory using the method selected by the controller.

Abstract: A paging controller (10) assigns pages to particular batch positions utilizing a metric that minimizes the gaps between messages in a batch so as to increase the efficiency and throughput of the system. The controller (10) stores information representing messages that are received for transmission in a queue (31-38) having the same associated frame number as the frame number of the message. A metric value representing a distance between an end of a message, if it is placed in a batch starting at a position associated with the message's frame number, and a subsequent batch position is calculated for the received messages identified in the queues (31-38). Messages are assigned to positions in the batches based upon the shortest calculated distance value so as to substantially minimize the gaps between adjacent messages in the batches.

Abstract: A communication system providing selective encoding of digital messages (408) comprising a plurality of transmitting devices (116) and a plurality of receiving devices (122). The transmitting devices (116) transmit an encoded address (404), encoded message vector (406) in a first portion of the message, and digital message (408) in a second portion of the message. The digital message (408) is encoded in the second portion of the message with an error correction code if the digital message is a data message (414), and without the overhead of an error correction code if the digital message (408) is a voice message (410). The receiving device (122) decodes the encoded address (404), encoded message vector (406), and digital message (408) transmitted by the transmitting devices (116) in the first and second portion of the message.

Abstract: A system controller (102) schedules an outbound selective call address (410) and an outbound message (430) at a position within a transmission cycle (330) of a synchronous outbound signaling protocol. The position and the outbound selective call address (410) are stored and linked to each other. The transmission cycle (330) is transmitted. A selective call transceiver (106) receives the transmission cycle (330), recovers the outbound message (430), and generates a response signal which includes an inbound address. The inbound address is determined from the position of the outbound selective call address (410) within the transmission cycle and is included in an inbound message which is transmitted.

Abstract: A transceiver apparatus for creating a wireless personal local area network between a computer terminal and one or more peripheral devices. A separate transceiver is connected to the computer terminal and to each peripheral device. The transceivers can be connected to the terminal or peripheral device either internally or externally. A low power radio is used to communicate information between the computer terminal and peripheral devices. Different transceivers can be used for modifying the carrier frequency and power of the local area network. The microprocessor is located inside each transceiver and controls the information flow of the transceiver including the communication protocol which allows each device to know if other devices are communicating, which devices are being communicated to, and selectively address the peripheral devices.
