Abstract: To address the need for a communication unit, a communication infrastructure, and method that shorten call-setup time while still providing the benefit of the QPCH, the present invention provides a communication unit (e.g., 103) that sends a page response before receiving a page message from the communication infrastructure, based on the values of the QPCH indicators. This “preemptive” page response shortens call-setup time. Because several communication units may send page responses before verifying whether they specifically are being paged, the infrastructure (e.g., 108-110) determines which page responses are valid (and processes them further) and which are false (and discards them).

Abstract: To address the need for a communication unit, a communication infrastructure, and method that extend battery life, the present invention provides a special page message (200) that is transmitted toward the beginning of a paging slot to indicate what groups of messages will be transmitted in the paging slot. This message allows communication units (e.g., 102-104) to determine near the beginning of the paging slot whether they need to continue monitoring the paging slot for messages or pages directed or of interest to them. The message also allows communication units that continue monitoring the paging slot to determine when they can cease the monitoring. Thus, communication units can return to a power-saving sleep mode more quickly than the prior art.

Abstract: In a wireless and/or wireline communications system (100), a method (400-536) and apparatus (200) for minimizing an amount of data (300) communicated between a source device (107, 108, 112 or 114) and a destination device (107, 108, 112 or 114) in order to modify an electronic document stored at said destination device. Said method and/or apparatus employs method steps and apparatus structure for editing a version of the electronic document stored at the source device via a set of input commands to create an edited version of the document. Thereafter, the set of input commands are transmitted to the destination device in order to modify the version of the electronic document stored at the destination device when the set of input commands are smaller in size than edited version of the document.

Abstract: Method for transmitting data packets between base site and designated mobile unit outside coverage area of base site comprises: identifying data packet; transmitting data packet to unit along calculated traffic path; determining if unit is designated unit; and retransmitting data packet from that unit until receiving unit is designated unit.

Abstract: The method operates in a wireless communication system, and includes receiving at a first base station having a first location, a widebeam signal from a first mobile communication unit having a second location; measuring, by the first base station, a characteristic of the received widebeam signal to form a first widebeam characteristic; receiving the widebeam signal at a second base station having a third location; measuring, by the second base station, the characteristic of the received widebeam signal to form a second widebeam characteristic; receiving, at the first base station, a narrowbeam signal from the first mobile communication unit; measuring, by the first base station, a characteristic of the received narrowbeam signal to form a first narrowbeam characteristic; receiving the narrowbeam signal at the second base station; measuring, by the second base station, the characteristic of the received narrowbeam signal to form a second narrowbeam characteristic; comparing the first widebeam characteristic a

Abstract: In a communication system a method for selecting a set of preferences for use during transmission of information to a particular destination anticipates selecting a list of one or more destinations, each destination having a key and a set of preferences, each preference further having a value. A historical database is indexed via the key to retrieve a set of database entries, each entry having a set of preferences, each preference further having a value. The retrieved database entries are filtered in order to identify those entries exhibiting a predefined set of criteria. After filtering, the preference values within the identified database entries are applied during transmission and subsequent processing of the information.

Abstract: At start-up, input/output bus is scanned to detect any unprocessed I/O devices and each device is scanned to locate any unprocessed data base partitions. If any are located, these partitions are stored in memory and the partitions are marked as processed. During run-time, a message is received indicating that a new I/O device has come on-line. The new I/O device is scanned for any unprocessed partitions. The information regarding the partitions is stored in memory and the partition is marked as processed. The process also functions during data base operations to make connections between a client and a data base. A sequential process routes a connection request message through one node at a time around the network until all of the tables requested have been connected. If the message is returned to the originating node with out being completed, a failure is reported to the client. A parallel process broadcasts the connection request message to all of the nodes on the network simultaneously.

Abstract: A real-time database management system in which data generated by a producer process is buffered in a plurality of update buffers and transmitted asynchronously into a consumer process, such as a database management system, so that neither the producer process nor the consumer process has to halt operations during I/O requests and data is not lost.

Abstract: In a real-time data base system, data is updated by reading the data and checking an exception flag associated with a locked status. If the exception flag is not set, the data is locked and read in an updatable fashion. If the data is locked, the data may still be read if a peek-mode access is requested.
