At selection, an actuation application (208) launches an application corresponding to the communication type and initiates a communication with the device identifier.
A method for reducing howling in a half-duplex communication system containing radios is presented. Prior to receiving an audio signal transmitted from a sending radio to receiving radios in the half-duplex communication system, the sending radio emits a talk-permit tone from a speaker. If any receiving radios are sufficiently close to the sending radio, they receive the talk-permit tone on their microphones. In that event, those radios, detect whether the talk-permit tone exceeds a predetermined threshold, and if that result occurs, the volume of each detecting radio speaker is automatically limited to a maximum allowed volume.
A sensor enhanced communication device (200) is provided with a wake mode, a standby mode and sleep mode.

Granting multiple communication paths for a single talkgroup call for interrupting a transmission or allowing a dispatch operator to listen to multiple units transmitting simultaneously on the same talkgroup call is disclosed. Upon a first unit being keyed, the controller assigns a first communication channel to a call, whereby the first unit begins transmitting using an inbound link of the first communication channel. If a second unit participating in the call is keyed during the call, the controller assigns a second communication channel to the call, and the second unit begins transmitting on the inbound link of the second communication channel. The call information for both transmissions from the first and second units may be simultaneously routed to dispatch consoles monitoring the call. If the controller determines that the first unit should be interrupted, the transmission from the second unit is broadcast by the base sites involved in the call.

A method and apparatus for quieting multiple channels is provided herein. During operation, transmission activity on each channel is analyzed and a best band is identified. Once the band is chosen, a wideband transmitter is utilized to transmit simultaneous reservation messages on consecutive channels simultaneously. Because a wideband transmitter is used to transmit simultaneous reservation messages on multiple consecutive channels, the above procedure quickly quiets multiple channels while minimizing the reservation duration of all channels as a result of quieting the channels.
A method and apparatus for quieting multiple channels on unlicensed spectrum is provided herein. During operation, a cluster head (or centralized controller such as a base station) will listen to determine if channels exist without primary system traffic. A message will then be sent out by the cluster head quieting the channels. All secondary nodes in the cluster will transmit a CTS-to-self if they do not hear any traffic by any primary system node (which may be nodes out of range of the cluster head) on the channels, otherwise they send a NAK on channels not being used by the hidden nodes. If a NAK is received by the cluster head, the process repeats until no NAK has been received. After the primary system is quieted, a poll message is sent by the cluster head to nodes instructing them to send a CTS-to-Self message so that the spectrum is quieted for the period indicated in the message.
To perform a channel inspection (200), a wireless communication device: monitors (202) a common announcement channel (CACH) until detecting that a first set of identified parameters associated with a signal on a first channel matches a second set of known parameters for the first channel; performs (204) an inspection on the first channel to determine whether the signal is of interest; and when the signal is not of interest, marks (206) the first channel to prevent another inspection from being performed on the first channel until after the channel mark is removed.

The ranking may be adapted based on mobility of the secondary's subscriber; and as such the secondary system communicates within the primary's spectrum using the adaptively ranked base stations. Channel selection may also be ranked. The technique and apparatus allows a cognitive radio (CR) network to operate within an incumbent network's spectrum.
A method and apparatus for external organization (EO) path length (EOPL) validation are provided. A relying party node (RPN) stores a current EO path length constraint (EOPLC) value, and an EOPL counter that maintains a count of an actual external organization path length. The RPN obtains a chain of certificates that link a subject node (SN) to its trust anchor, and processes the certificates in the chain. When a certificate has a lower EOPLC than the current EOPLC value, the RPN replaces the current EOPLC value with the lower EOPLC. When the certificate currently being evaluated includes an enabled EO flag, the RPN increments the EOPL counter by one. The EOPL validation fails when the EOPL counter is greater than the current EOPLC value, and is successful when the last remaining certificate in the chain is processed without having the EOPL counter exceed the current EOPLC value.

SYSTEM AND METHOD FOR FACILITATING FAST GROUP COMMUNICATION BETWEEN SUBSCRIBERS IN A PEER-TO-PEER WIDE AREA NETWORK
A method of operating a peer to facilitate fast group communication between subscribers in a peer-to-peer wide area network is disclosed. In the peer-to-peer wide area network, each of the subscribers are affiliated to a talkgroup, and further registered to at least one peer within the peer-to-peer wide area network. In operation, the peer exchanges messages with other peers to determine that one or more peers listed in a talkgroup topology is still active. When the peer receives a media for a talkgroup from a subscriber affiliated to the talkgroup, the peer duplicates the media for the talkgroup, and unicasts the duplicate media to the one or more peers that are listed as active in the talkgroup topology to enable the one or more peers to deliver the media to the respectively registered subscribers affiliated to the talkgroup.

According to some embodiments, the method includes establishing at a PKI event logging (PEL) server a process to achieve secure communications with the relying node (step 705). Next, the PEL server processes reported PKI transaction event data received from the relying node (step 710). The reported PKI transaction event data describe the PKI transaction event between the relying node and the subject node. The reported PKI transaction event data are then transmitted from the PEL server to the subject node (step 715). The subject node can thus compare the reported PKI transaction event data with corresponding local PKI transaction event data to confirm the authenticity of the PKI transaction event.

A method provides for identifying short radar signals in presence of interfering signals from various sources applicable to U-NII devices. The method includes collecting a set of information about received interfering signals until the End-Of-Burst (EOB) condition is identified. When the EOB is identified, the set information about the received train of interfering signals is processed. The algorithm selects the time interval between two pulses as a possible Pulse Repetition Interval (PRI) and checks if the same time interval or a multiple of it can be found between other pulses in the collected set, with some small acceptable error. Pulses matching the criteria are considered as potential radar pulses. When at least one pulse has been identified as a potential radar pulse for a number of times larger than a predefined limit, it is concluded that that pulse has been generated by a radar installation.

METHOD FOR PROXIMITY DETECTION IN A WIRELESS COMMUNICATION NETWORK
A method for proximity detection in a wireless communication network. A node attempts to determine the proximity of the closest neighboring node by transmitting a ranging request. Other nodes respond, and the first node to receive and respond to the request will have the shortest response time and thus will be the closest node. Exact ranges can be determined by applying Time-Of-Arrival (TOA) techniques to node response times. To further avoid collisions, one or more frames of the response messages can be same, making the multiple responses appear as multi-path. The group of responders can be narrowed and individual groups probed in a search pattern until the single nearest node is known or range of the nearest node is known. The ranging node may then use ordinary unicast mechanisms to probe this node, or begin scanning the groups again, or interleave the two mechanisms as desired.

H04M 1/2745 - Devices whereby a plurality of signals may be stored simultaneously with provision for storing more than one subscriber number at a time using static electronic memories, e.g. chips
Portable battery operated electronic devices often use a "sleep mode" for energy conservation. A key feature introduced in the IEEE 802 standard ensures power-efficient operation of these battery operated mobile devices. However, the standard fails to define what will trigger a device into the sleep mode while other systems define "waiting time threshold" as a time for which a Mobile Subscriber Station (MSS) waits before entering into sleep mode which has a constant duration. An embodiment of the present invention uses a unique method (1500) and algorithm for optimizing waiting time threshold (1509) according to traffic arrival pattern for uplink (UL) and downlink (DL) data packets. This leads to significant reduction in energy consumption with little increase in average waiting delay and acceptable end- to-end delay for non real time traffic.

NON-3GPP ACCESS TO 3GPP ACCESS INTER-RAT HANDOVER WITH RESOURCE PREPARATION
A pre-registration phase (800) and a resource preparation phase (900) reduce latency when a user equipment (UE) (210) hands over from a non-3GPP radio access (220) such as WiMAX to an 3GPP radio access network (230) such as E-UTRAN. During a pre-registration phase (800), a Forward Attachment Function (260) receives a pre-attach request message (833) and creates (860) a 3GPP mobility management context for the UE (210) that is valid for E-UTRAN access. During a resource preparation phase (900), the mobility management context is transferred to a mobility management entity (MME) (240) and radio and transport resources are reserved for the UE (210) at the target E-UTRAN cell (230). When a handover is initiated (910) by either the UE or the non-3GPP network, the time-consuming authentication and authorization procedures that are performed during the process of pre- registration can be skipped. Additionally, radio and transport resources have already been assigned to the UE and thus do not have to be set-up when the handover executes.

A method for synchronizing media reproduction across heterogeneous networks is presented. The networks include end-to-end IP broadband and narrowband simulcast networks that contain broadband and narrowband devices associated with a common communications group. A controller in the networks determines delay times for reproduction of a media stream across devices in the networks and establishes the longest delay time. The longest delay time is used to calculate appropriate transmission and reproduction timestamps to permit the devices to reproduce the provided media stream in synchronization. Narrowband base stations repeat the media stream at the time specified by a transmission timestamp, and broadband end devices reproduce the media stream at the time specified by a reproduction timestamp. By synchronizing the presentation time, the devices present the media at substantially the same time and are granted fair rights to communicate with one another.

A dynamic and distributive aggregation method in which a node determines the frame size of an aggregated frame based on or according to a transmission time of one or more of the received frames. This scheme to aggregate frames is based on the average packet size and average transmission time in the neighborhood. The method enables the aggregated packet size to dynamically change based on the neighborhood conditions. Usage of link rates and fair transmission time assignment enables the high data rate nodes to send more traffic but not to an extent of over-utilizing the channel thus achieving higher throughput efficiencies while maintaining fairness within a high data rate multi-hop wireless communication network.
Each node in a wireless communication network adds information in hello messages wherein the information comprises the number of hello messages received at the node from a plurality of nodes.

The first node extracts the additional information from the received hello message and based on the extracted additional information, the first node determines at least one channel performance metric. Based on the at least one channel performance metric the first node determines density of neighboring nodes in the wireless communication network.
