Abstract: A method and apparatus for determining stream weights is provided herein. During operation, an uplink direction of arrival (DOA) and a downlink direction of departure (DOD) calibration procedure is implemented using uplink signals and GPS information from a subset of mobiles without the need of calibration circuitry at the base. Because the presented calibration procedure needs no new hardware it can be deployed in existing deployments with only a soft-ware upgrade.

Abstract: An intelligent subscriber and method of the subscriber roaming between base stations is presented. An unexpected uplink, such as a request to initiate communication, a SMS communication or request to change talkgroup, is transmitted to a base station. When a predetermined number of such uplinks remain unacknowledged by the base station, the subscriber determines that terminal failure of the base station has occurred. An ordered list of available base stations able to serve the subscriber is maintained in subscriber memory. The ordering is based on service level and within each service level by radio measurements. The list is manipulated such that the service level of the original base station is minimized A new base station is selected using the manipulated ordered list. The service level of the original base station is then restored. A communication is sent to an external host to record information about the terminal failure.

Abstract: A method for direct mode channel access in a time division multiple access (TDMA) system includes: assigning a radio operating in the TDMA system to transmission on a first time slot of a direct mode channel; initiating a request for a direct mode transmission on the direct mode channel; determining, by the radio, whether there is communication activity present in the first time slot or a second time slot of the direct mode channel; aligning, by the radio, to a selected slot timing based on the determining step; and transmitting, by the radio, with the selected slot timing on the first time slot.

Abstract: A method for synchronizing the direct mode TDMA transmission of a set of radios by following a selected radio as the leader includes: receiving, by a radio, a communication from an other radio; identifying, by the radio, a leader according to a leadership election rule using the received communication from the other radio and a current leader information; setting, by the radio, the identified leader as its leader; and synchronizing, by the radio, a time slot boundary with a time slot boundary defined by the leader.

Abstract: A smart method (100) and module (300) to minimize standby loss is disclosed. The method (100) can include the steps of: detecting (110) a current parameter at a load node; determining (120) whether a current parameter threshold has been reached; and disabling (13) power delivery based on determining whether the current parameter threshold has been reached. Advantageously, the smart method (100) can provide minimal to zero standby loss, when a current parameter threshold has been reached. This method has use in many electronic devices and particularly in battery chargers, for example, when a predetermined current parameter threshold has been reached or an energy storage device (battery) charge is complete, minimal or zero standby loss can be attained. In one embodiment, the smart method (100) can substantially fully switch off AC mains to eliminate standby loss.

Abstract: A hosted inter-radio frequency subsystem interface (HIF) maintains a list of affiliated radio frequency subsystems (RFSSs), the list identifies at least one serving RFSS. An affiliation request is transmitted from the HIF to the home RFSS, which is a home RFSS of the group. The HIF receives from the serving RFSS a request to initiate an inter-RFSS group call to the group using HIF addressing. The HIF transmits a request to the home RFSS to initiate the inter-RFSS group call using serving RFSS addressing. A data packet from the home RFSS or the serving RFSS is received at the HIF. Upon receipt, the HIF transmits a copy of the data packet to the serving RFSS if the data packet was received from the home RFSS; otherwise, the HIF transmits a copy of the data packet to the home RFSS if the data packet was received from the serving RFSS.

Abstract: A method and device enable establishing an inter-radio frequency subsystem interface (ISSI) unit-to-unit call between a calling unit of a calling home radio frequency subsystem (RFSS), and a called unit of a called home RFSS, through a hosted ISSI function (HIF). The method includes processing, at the HIF, a first invite message received from the calling home RFSS, wherein the first invite message includes a first request uniform resource identifier (URI) that designates an alias system unit identification (SU-ID). In response to the first invite message, transmitting, from the HIF to the called home RFSS, a second invite message, including a second request URI that designates a real SU-ID, wherein the HIF acts as the calling home RFSS. The unit-to-unit call is thus established between the calling unit and the called unit through the calling home RFSS, the HIF, and the called home RFSS.

Abstract: Systems and methods for vetting data include receiving a notification at a second processor that a first processor has written first output data to an output data buffer in an output device. A hardware-implemented buffer access flag controls a permission for the first processor to write data to the output data buffer. The second processor sets the hardware-implemented buffer access flag to a first setting that prevents the first processor from writing additional output data to the output data buffer while the first output data in the output data buffer is being inspected. The second processor has a read-write permission to the hardware-implemented buffer access flag. The first processor has a read-only permission to the hardware-implemented buffer access flag.

Abstract: Authentication methods are used to authenticate, a device1 having an ESN1 (electronic serial number), a device2 having an ESN2, and/or a user of the devices. In one implementation, device1 receives the ESN2 in a near-field signal; derives an authentication result as a function of the ESN1 and ESN2; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device1 authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN1 and ESN2. In a second implementation, device1 generates a RAND1 (random number) and sends the RAND1 to device2 over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND1 from both device1 and device2.
