Jun 30, 2010

Appl. No.:

12/826974

Inventors:

Jeff S. Anderson - Itasca IL, US
Henry W. Anderson - Palatine IL, US
Bradley M. Hiben - Glen Ellyn IL, US

Assignee:

Motorola Solutions, Inc. - Schaumburg IL

International Classification:

H04L 12/28

US Classification:

370390, 370338, 370432

Abstract:

A method, device, and system for establishing and maintaining a multicast group call. The method includes monitoring one or more link parameters for each of a plurality of communication devices associated with the multicast group call. The method further includes selecting, for each of the plurality of communication devices, a sector from a plurality of permitted sectors, the selected sector providing an associated highest signal strength for the communication device and forming a multicast communication zone based on the selected sectors. The method further proceeds with calculating a signal to interference plus noise ratio (SINR) for each communication device based on the formed multicast communication zone, identifying a communication device with a lowest SINR, updating a spectral efficiency metric relative to the formed multicast communication zone based on the lowest SINR, and establishing the multicast group call when the updated spectral efficiency metric meets a minimum expected spectral efficiency metric.

International Classification:

H04B 7/00

US Classification:

455519, 455521

Abstract:

An apparatus and method for dynamic group prioritization in a communication network includes a first step () of defining a dynamic list of group participants by an application, such as a dispatch function. A next step () includes sending a request to a Group Management Function, wherein the request includes a requested group priority and the list of group participants. A next step () includes allocating a unique identifier to the group and assigning a group priority to the group. A next step () includes notifying the application, group participants, and network of the unique identifier and the network of the assigned group priority. The assigned priority of the group and its flows can be dynamically altered in real-time while the group is active.

International Classification:

H04B 15/00

H04W 72/04

US Classification:

370329, 455501, 4554041, 4554521

Abstract:

Methods and apparatus are provided for mitigating interference between spectrally distinct wireless communication networks employing co-located, collaborating radios. A first base station is in a first network and communicates with a first radio within a first frequency range, and a second base station is in a second network and communicates with a second radio in a second frequency range. The first and second radios are geographically co-located, for example, within a public safety vehicle. The first radio determines a maximum level of interference it will accept based on current operational parameters, and communicates a corresponding threshold value to the second radio through a data link. The second radio sends a request to its base station to employ interim scheduling constraints governing uplink transmissions from the second radio, to thereby limit out of band emissions received by the first radio to a range that is less than the threshold interference level.

International Classification:

H04W 72/04
H04B 15/00

US Classification:

455 631

Abstract:

A communication pathway () can be established between physically collocated narrowband () and broadband () devices. The narrowband device () can identify a communication channel. A transmission frequency used by the broadband device () can be spectrally-proximate to a reception frequency used by the narrowband device () in a frequency range associated with the communication channel, resulting in interference of the narrowband device's () reception when the broadband device () is transmitting and the narrowband device () is receiving concurrently. The narrowband device () can instruct the broadband device () to switch to a transmission spectrum block that is spectrally separated from the reception spectrum block of the communication channel to minimize interference between the devices when the narrowband device () handles a call assignment.

International Classification:

H04W 72/00

US Classification:

370329

Abstract:

A method for transmitting data in a single-frequency network in a Long Term Evolution (LTE) network includes receiving media for broadcast in a broadcast area of a plurality of broadcast areas associated with a single-frequency network, wherein the broadcast area comprises a plurality of cells; identifying a subset of defined broadcast resources for broadcasting the media to the broadcast area; broadcasting the media to the broadcast area using the subset of defined broadcast resources; and broadcasting a null pattern on the subset of defined broadcast resources in adjacent broadcast areas to the broadcast area. An associated LTE network and broadcast controller are also described.
