Patent number: 8243750Abstract: A method for Fixed Network Equipment (FNE) to control the three of four and one of four slow associated control channel (SACCH) pattern on an Association of Public-Safety Communications Officials (APCO) Project 25 (P25) trunked voice channel is provided. Knowledge of this pattern by both the FNE and radio allows for unique information to be signaled in each type of SACCH. According to some embodiments, an operation enables controlling the floor (inbound) while there is an independent outbound (floor) (e.g. Console takeover). The provided operation also allows each radio to differentiate inbound floor control signaling from outbound caller identification (ID). Having the infrastructure control the inbound SACCH pattern and communicate this to all radios, makes the correct detection of the transmitted pattern from the radio more reliable.Type: GrantFiled: October 30, 2009Date of Patent: August 14, 2012Assignee: Motorola Solutions, Inc.Inventors: Daniel J.

Patent number: 8144846Abstract: A system and method for interrupting a transmitting communication unit in a communication system. When a call is first initiated, the call is assigned to a communication channel and broadcast from a base site using the assigned communication channel. If it is determined that a transmitting communication unit should be interrupted, a zone controller signals a base site to generate an interrupt message. The base site generates an interrupt message containing an identification code for the transmitting communication unit and broadcasts the interrupt message on an outbound link of the communication channel. The transmitting communication unit, while transmitting on an inbound link of the communication channel, continuously monitors the outbound link. If the transmitting communication unit receives, on the outbound link, an interrupt message containing an identification code matching its own identification code, the transmitting communication unit stops transmitting.Type: GrantFiled: January 8, 2007Date of Patent: March 27, 2012Assignee: Motorola Solutions, Inc.Inventors: John M.

Patent number: 8098639Abstract: System and method for efficiently managing communication channel assignments within talkgroups having dual mode communication units capable of operating on a first communication channel type and on a second communication channel type, and single mode communication units capable of operating only on the second communication channel type. If, at a base site, each of the communication units associated with a talkgroup is a dual mode communication unit, a call for that talkgroup is assigned to be broadcast using a channel of the first communication channel type. If, at least one of the communication units associated with the talkgroup at the base site is a single mode communication unit, the call for that talkgroup is assigned to a channel of the second communication channel type. As communication units roam between sites, channel assignments are continuously updated based on the types of communication units at each base site at any one time.Type: GrantFiled: January 2, 2007Date of Patent: January 17, 2012Assignee: Motorola Solutions, Inc.Inventors: Daniel J.

Patent number: 7986692Abstract: A system and method for transmitting call information in a communication system having sites with long link delays. Upon a call being initiated within the communication system, a zone controller determines the participating sites that are to be involved in the call and assigns an IP multicast group address for the call. The zone controller also determines whether any of the participating sites have a long link delay. If any of the participating sites do have a long link delay, the zone controller also assigns an IP unicast address for each such site. The call information is then transmitted both on the IP multicast address as well as on each assigned IP unicast address to ensure that the call is received by each participating site without the loss of call information.Type: GrantFiled: March 8, 2007Date of Patent: July 26, 2011Assignee: Motorola Solutions, Inc.Inventors: Daniel J. McDonald, John W. Maher

Patent number: 7970426Abstract: The present disclosure provides an efficient and effective method for allocating provisional PUIDs and PGIDs to subscriber units and groups during a failure, such that when the communication system recovers, there is a decrease in or elimination of the number of dropped or missed communications. The present disclosure reserves a range of provisional PUIDs and PGIDs for resource controllers operating in a region of system failure to assign when subscriber units roam into the region of failure in the communication system. The present disclosure addresses creating PUID and PGID ranges for resource controllers to assign to roaming subscriber units in order to allow for assignment of PUIDs and PGIDs during periods of subsystem isolation and site trunking, i.e., when the particular site or subsystem cannot communicate with the rest of the communication system. The present disclosure also addresses recovering from these situations, re-registration, and reallocation of PUIDs and PGIDs.Type: GrantFiled: September 10, 2008Date of Patent: June 28, 2011Assignee: Motorola Solutions, Inc.Inventors: Brian R.

Patent number: 7917131Abstract: A system and method for processing calls in a communication system utilizing distributed signaling. When a call signal having distributed identification data is received on a communication channel, the call information (such a voice, data, video, etc.) is initially passed through the system without verification until sufficient identification data (such as the color code) has been obtained to determine whether the source of the call is valid. Once sufficient identification data has been obtained, the source is verified. If the source is valid, the call information continues to be passed through the system. However, if source is invalid, the call information is blocked for the present call as well as for subsequent calls on the same communication channel, and passing of the call information through the system does not resume until a received call is subsequently assessed to be valid.Type: GrantFiled: September 20, 2007Date of Patent: March 29, 2011Assignee: Motorola Solutions, Inc.Inventors: Gregory A.
