Appl. No.:

10/052800

Inventors:

Stephen Sanders - Glenview IL, US
Paul Bocci - Roselle IL, US
Gregory Dertz - Algonquin IL, US

International Classification:

H04Q007/20

US Classification:

455/466000, 455/521000, 455/414000

Abstract:

A wireless communication system () contains a number of service providers () that provide different services to communication units (-). The communication units (-) are limited as to how many of the services they can concurrently receive. Each communication unit (-) is associated with a service manage agent (SMA) (-) that manages the provision of the services to the communication unit (-). In one embodiment, each SMA (-) manages the provision of the services to only one of the communication units (-).

Appl. No.:

8/794708

Inventors:

Eugene J. Bruckert - Arlington Heights IL
Stephen H. Sanders - Chicago IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q7/20

US Classification:

455456

Abstract:

The location of a remote unit (113) within a wireless communication system (100) is determined by all base stations (101) within the wireless communication system (100) initiating a first page (wide-area location page) that is broadcast to the remote unit (113) over a paging channel. The serving and neighbor base stations are determined from the remote unit's (113) response to the wide-area location page, and those base stations are instructed to tune receiving elements to obtain data that will be transmitted by the remote unit (113) during location. A second message (Location Page Message) is then broadcast to the remote unit (113) via the serving base station (101). The Location Page Message instructs the remote unit (113) to periodically transmit a known Remote Unit Location Message (RULM) with increasing power levels for a predetermined number of times so that the remote unit's (113) location can be achieved.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 700

US Classification:

370331

Abstract:

The present invention provides a method of handing-off a remote unit (113) from a first base station (101) to a second base station (102). The remote unit (113) communicates with the first base station (101) and establishes communication with a second base station (102). It is then determined, preferably by the remote unit (113), that the remote unit (113) should hand-off to the second base station (102). An overhead information start time is then determined. The remote unit (102) may determine when the overhead information will be broadcast by the second bast station (102), thereby establishing an overhead information start time. The overhead information start time is the time when overhead information will be transmitted from the second base station (102). The first base station (101) and the second base station (102) may be synchronized to transmit the overhead information at approximately the same time. In this manner, the remote unit (102) can determine the overhead information start time at the second base station (102) by monitoring the overhead information start time at the first base station (101).

International Classification:

H04Q 722

US Classification:

455426

Abstract:

A dispatch controller (103) located logically external to an existing telephone network (101) is coupled to the existing telephone network. When an originating communication device (e. g. , 111) desires to initiate a dispatch call, the originating device transmits a call request to the existing telephone network, wherein the call request includes an identification (ID) of the originating device and a target address associated with the dispatch controller. The existing telephone network provides the call request to the dispatch controller. Upon receiving the call request, the dispatch controller retrieves dispatch-related information from a database (105) coupled to the dispatch controller based on the originating device's ID. Based on the retrieved dispatch-related information, the dispatch controller identifies a group of target communication devices (e. g. , 107-110) for the dispatch call.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q7/34

US Classification:

455456

Abstract:

Remote units (113) that require locating are managed by a queue controller (180) such that the number and location of remote units (113) that are transmitting at increased power at any given time is limited. In particular, a queue controller (180) places identification information for remote units (113) requiring location onto queues (203) associated with base stations supplying reference pilots to the remote units (113). Additionally, identification (ID) information for the remote units (113) requiring location is placed onto queues (203) associated with base stations neighboring the base stations supplying the reference pilot to the remote units (113). The queues (203) operate on a first-in-first-out (FIFO) basis, that output remote unit ID at periodic intervals. Once all queues (203) have been emptied of the ID of a particular remote unit (113), location takes place for that remote unit (113).
