Abrégé

An electronic communication device (100) is configured to automatically create reminders in a reminder application (206) in response to received communications, interruption events, or other occurrences. For example, when an interruption event is detected, a soft key (103,104) is configured with a reminder creation function. Upon actuation of the soft key (103,104) the reminder application (206) automatically creates a reminder by associating a communication type and a device identifier with the reminder. A user is then able to select the reminder from a list. At selection, an actuation application (208) launches an application corresponding to the communication type and initiates a communication with the device identifier.

Abrégé

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.

Abrégé

A sensor enhanced communication device (200) is provided with a wake mode, a standby mode and sleep mode. The sleep mode is a periodic occurrence within the standby mode which places a cluster of sensors and transducers (202) into a state of arousal in which the sensitivity of the transducers and sensors is increased while the sampling rate is decreased. Incremental learning can occur during the sleep mode as well as basic memory transfers. Since the cluster does not have to re-acquire information upon entering wake mode, the overall power efficiency is improved.

Abrégé

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.

Abrégé

A device receives a signal and, prior to demodulating the signal determines whether carrier is present in the received signal based on the correlation depth of the received signal. The device determines (210) a plurality of values for the received signal that indicate the amount of correlation in the received signal and detects the presence of the carrier in the received signal as a function of the plurality of values. The plurality of values can include autocorrelation values and prediction coefficients, wherein the autocorrelation values are estimated based on an autocorrelation function derived for the received signal, and the prediction coefficients are generated using a prediction model that is derived as a function of the autocorrelation values. The prediction coefficients can be summed to generate (224) a decision statistic that is compared (228) to a detection threshold to detect the presence of the carrier.

Abrégé

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.

Abrégé

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.

Abrégé

A device detects (206, 222) a first signal on a channel that is one of a plurality of channels arranged in a first order on a list, with each channel being associated with a different site in a multi-site communication system. Upon detecting the first signal, the device attempts to measure and record signal strength of a signal at each channel on the list based on the first order beginning with the detected first signal (208, 210, 214, 216), and selects (221, 218, 220) as a home site the site associated with the channel having the signal with the highest recorded signal strength. The device rearranges (220) the channels on the list into a second order based on the recorded signal strengths with the home site channel at the top. If necessary, the radio attempts to awaken its repeaters one after another based on the second order until a repeater is found to transmit a signal.

Abrégé

A technique for a secondary communication system to utilize spectrum designated to another (or primary) communication system is provided. By ranking a plurality of secondary base stations based on base station transmit power, calculated required transmit power and path loss, a set of criteria is developed for selecting a highest ranked secondary base station for operation within a primary's spectrum. 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.

Abrégé

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.

Method and apparatus are disclosed for synchronizing multimedia in asynchronous networks. In this invention, clock domains are first reduced to separate hardware clock correction circuits at the separate endpoints of an asynchronous network. At each end of the network node, the controllable input device such as a video device is synchronized to the non-controllable output device such as a set top box to prevent unknown or poor-quality alterations by the output device. Output device timestamp packets are regularly sent to the input device, which then adjusts its clock accordingly. The exchange of packets between input devices over the asynchronous network is then subjected to a software-based scheme to effectively synchronize these devices.

Abrégé

A method and device for confirming authenticity of a public key infrastructure (PKI) transaction event between a relying node and a subject node in a communication network enables improved network security. 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.

Methods of automatically populating a secure group list in a key variable loader and of providing keys to a secure group are presented. After a user selects a secure group and encryption algorithm using inputs of the loader, the loader provides a group identifier and corresponding key for the group. The group identifier, encryption algorithm, and key are transmitted to a portable communication device over a physical connection between the two while a device identifier of the communication device is transmitted concurrently to the loader. The key variable loader automatically populates a stored list of subscribers of the group with the device identifier. When it is desired to transmit a new key to all of or fewer than all of the subscribers, one of the subscribers is connected with the loader and used to wirelessly transmit a new key to the remaining subscribers.

Abrégé

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.

Abrégé

A method of encrypting a unique cryptographic entity (UCE), where a client device receives a global-key (GK-) encrypted UKD comprising a GK-encrypted UCE and a GK-encrypted unit key number (UKN). The client device verifies that the GK-encrypted UKN is the same as a pre-provisioned value and then decrypts the GK-encrypted UKD using a global key (GK). The client device then re-encrypts the decrypted UKD using a device user key (DUK) to determine a DUK-encrypted UCE and a DUK-encrypted UKN. The DUK-encrypted UKN is verified as not equal to the GK-encrypted UKN. The DUK-encrypted UKN is then appended to the DUK-encrypted UCE to form a DUK-encrypted UKD and stored in a memory.

Abrégé

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.

Abrégé

The application discloses a method and apparatus for adjusting internal load impedances, by section, at feed points present on a distributed amplifier's output transmission line. The method includes determining a summing-point load impedance (Zx) at an off-chip output transmission line of the distributed amplifier. The method further includes determining a driving-point load impedance (Zd) at an output of an on-chip power transistor. The driving-point load impedance diverges and disperses over frequency from that summing-point load impedance due to reactance of at least one on-chip component coupled to the output of the on-chip power transistor. The method then includes determining and providing an offset to summing-point load impedance (Zx) based on the driving-point load impedance (Zd) such that the driving-point load impedance (Zd) converges to the summing-point load impedance (Zx) of that distributed amplifier section.

Abrégé

A communication system (100) routes a bearer path of a communication session between an originating Node B (112) and a terminating Node B (e.g., Node B 122) via an X2 interface (116), bypassing an IMS core network (152), while continuing to route the signaling path to an IMS network (150), thereby allowing the IMS network to retain control of the bearer path while avoiding delay, potential for bearer stream data loss and jitter, and additional backhaul capacity requirements that result from routing the bearer path between the originating and terminating Node Bs via the IMS core network. In determining whether the bearer path may bypass the IMS core network, the communication system determines whether IMS core network bearer associated services are required for the communication session such that a bearer path of the call will need to be routed to the IMS core network in order to provide such services.

Abrégé

Disclosed are methods including a new optimization criterion, Maximum Mesh Coverage (MMC) for a channel selection process during the formation of ad hoc networks. By using MMC, the intelligent access point (IAP) will select a channel to connect as many mesh nodes as possible in addition to meeting the interference minimization requirement. During mesh formation, the channel interference information for a node is first scanned by the node and then broadcast in its available channels. An iteration procedure for meshing network formation allows the IAP to gradually obtain the global channel interference information and broadcast the same so that a maximum number of n-hop nodes communicate on the same frequency channel. If a channel change is required to accommodate the channel interference status of candidate nodes, a channel change message will be broadcast to better achieve the large coverage advantage of a multi-hop configuration.

Abrégé

A method and apparatus is provided for establishing communication pathways between infrastructure devices in a wide area communication network prior to transmission of a group message packet by a source wireless communication device (WCD). In one implementation, the infrastructure devices (IDs) can include a home ID of the source WCD, a first ID and a second ID. A home steward module (HSM) of the source WCD generates a distribution list (DL) for communications from the source WCD to a first communication group (CG), and communicates it to an envoy packet duplicator module (EPDM) located at the first ID. The first CG includes, for example, a first destination WCD. A first network socket of the EPDM is communicated from the HSM to a second envoy module (located at the second ID) for the first destination WCD. The HSM maps a second network socket for the second envoy module to an identifier of the first destination WCD, and communicates this mapping to the EPDM. A first communication connection can then be established between the first network socket and the second network socket.

Abrégé

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.

Abrégé

Disclosed is a "light weight" protocol used to coordinate shared copies of a data element (106). A central repository (102) holds a master copy of the data element (106). Applications (104a, 104b, 104c) "subscribe" (200) to the data element (106) (or to an aspect (108) of it) by sending a message to the central repository (102). Whenever the data element (106) (or aspect (108)) is changed, applications (104a, 104b, 104c) that have subscribed to the data element (106) (or aspect (108)) are notified (204) of the change. When an application (104a, 104b, 104c) wishes to change the value of a subscribed aspect (108), it sends (210) an update request to the central repository (102). The central repository (102) changes (306) the master copy of the data aspect (108) to the requested value and then informs (306) all subscribed applications (104a, 104b, 104c) of the new data value. If two applications (104a, 104b) both wish to change the value of the same data aspect (108), they send (210) their update requests, and the central repository (102) processes (306) them in the order in which they are received.

Abrégé

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.

Abrégé

A method (300) and apparatus (120) are disclosed that authenticate a user of a mobile device (120) with motion sensors (210). During a learning session (500), the user initializes the mobile device (120) by providing (510) a motion sample. The mobile device (120) extracts (520) motion features that are unique to the user and converts (530, 550) them to parity bits (340) and to a password shadow (370). During a recognition session (300), a motion pattern is gathered (310) from the user moving the mobile device (120) as if it were a virtual pen. The mobile device (120) then uses the stored parity bits (340) to correct (330) small differences between motion patterns exhibited by the same user at different times. The mobile device (120) converts (350) the corrected motion pattern into a motion password that is compared (360) with the stored password shadow (370). A user is authenticated only if the two values coincide. The system erases (420) the generated motion password.

Abrégé

A system and method for interrupting a transmitting device during a call. In the system, calls are transmitted from a first device on a communication channel as a series of channel frames. At predetermined times during the transmission, the transmitting device is configured to drop channel frames, resulting in open channel frame periods where the transmitting device is not transmitting on the communication channel. During these open channel frame periods, the transmitting device is also configured to switch to a receiving mode. Other devices in the system are capable of switching into a transmitting mode during the open channel frame periods and, when applicable, sending an interrupt request on the communication channel to the transmitting device in order to request access to the channel.

Abrégé

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.

Abrégé

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.

Abrégé

A method and apparatus for reducing in-band spurs in a fractional-N synthesizer (100) includes generating a compensated current signal by a charge pump (108) coupled to a phase detector (106). The compensated current signal includes in-band spurs having frequencies within a frequency bandwidth associated with a loop filter (110). The method then includes selectively dithering the compensated current signal with a sufficient dither level to spread the frequencies of in-band spurs beyond the frequency bandwidth associated with the loop filter (110). The dithered compensated current signal is then passed through the loop filter (110) for filtering the in-band spurs having frequencies beyond the frequency bandwidth. The method then includes generating a voltage controlled oscillator (VCO) signal with reduced in-band spurs proportional to the filtered compensated current signal.
