Patent number: 9055562Abstract: A scheduling component associated with a data channel configures initial reserved bandwidth allocations for each agency permitted access to a shared data channel. When sufficient bandwidth is available on the shared data channel to meet all bandwidth requests, the scheduling component schedules access to available random access slots on the shared data channel. When an agency accesses a scheduled random access slot, the agency is able to reserve additional reserved slots on the shared data channel for data transmission on an on-demand basis. The scheduling component enables bandwidth management controls when one or more requests for the additional reserved slots on the shared data channel cannot be fulfilled due to insufficient available additional reserved slots on the shared data channel and controls access to the shared data channel by distributing limited access permissions for future available random access slots to agencies permitted access to the shared data channel.Type: GrantFiled: September 28, 2012Date of Patent: June 9, 2015Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Stephen H.

Patent number: 8660542Abstract: A multi-carrier receiver radio monitors frequency channels associated with at least one talkgroup to which a multi-carrier receiver radio subscribes. The talkgroup is associated with a set of frequency channels that may carry group call activity. The radio monitors each frequency channel of the set of frequency channels associated with the talkgroup for group call activity. During monitoring, when a new call is detected on one frequency channel of the set of frequency channels associated with the talkgroup, the radio joins the new call. While joined to the new call, the radio continues to monitor the set of frequency channels associated with the talkgroup for additional transmissions to the talkgroup and to monitor a set of frequency channels associated with another talkgroup to which the multi-carrier receiver radio also subscribes for group call activity on the other talkgroup.Type: GrantFiled: December 20, 2011Date of Patent: February 25, 2014Assignee: Motorola Solutions, Inc.Inventors: Daniel J.

Patent number: 7801067Abstract: A subscriber (100) transmits data on a first data channel. While transmitting, the subscriber tracks the number of collisions it experiences on the first data channel (206). When the number of collisions reaches a threshold value, the subscriber transmits a reassignment request to move to a new data channel. Upon receipt of the reassignment request, a central processor (102) assumes that the first data channel is loaded. The central processor will then compare an incoming data rate to a value to determine if the first data channel is actually loaded, wherein the incoming data rate is measured by the central processor at the time the subscriber requested reassignment.Type: GrantFiled: August 5, 2003Date of Patent: September 21, 2010Assignee: Motorola, Inc.Inventors: Michael J.

Patent number: 5450611Abstract: Requesting (transmitting) subscriber units may immediately begin transmitting an information signal over an assigned communication channel. Receiving subscriber units immediately unmute their speakers and monitor the assigned communication channel and attempt to detect a code, which indicates that they are monitoring the correct communication channel. At the central station (repeater), the information signal may be immediately repeated, unless an interference signal is present. In this way, the information signal may be rapidly disseminated (repeated) to improve subscriber access time, while providing assurance that the receiving subscribers will not receive a noise signal or the interference signal.Type: GrantFiled: August 23, 1991Date of Patent: September 12, 1995Assignee: Motorola, Inc.Inventors: Michael J.
