Abstract:
A method and apparatus for scanning amongst two-way radios is disclosed. The method includes applying a scan probability index (SPI) to each member of a scan list, the SPI indicating a likelihood of channel activity. The SPI is dynamically updated by a variety of processes. Members are loaded from the scan list, and the SPI of the loaded member is compared to a threshold. Members are skipped or checked for activity based on the SPI passing or failing the threshold. Members having a sufficient SPI will proceed to have detected channel activity decoded. The method and apparatus may utilize both normal scan members and vote scan member frequencies.
Abstract:
Systems and methods for managing power consumption on a trunked network include listening to a control channel on a trunked system with a trunked pager, and receiving a voice channel assignment. The trunked pager listens for voice traffic on the assigned voice channel while in a standby mode. Voice traffic is detected and the trunked pager determines whether the voice traffic is for a communication group that includes the trunked pager. If so, the trunked pager unmutes and listens to the voice traffic. Upon termination of the voice traffic, the trunked pager returns to the control channel to listen for a different voice channel assignment. Otherwise, the trunked pager directly returns to the control channel to listen for a different voice channel assignment.
Abstract:
A method and system for assigning priority to a talk group of a plurality of talk groups in a communication network (100) is provided. The method includes detecting (304) activity on a first talk group (108) via a Vehicular Repeater (VR) (106). The first talk group is associated with a lower priority than that of a second talk group (110). The method also comprises assigning (306) a higher priority to the first talk group and the lower priority to the second talk group, based on the step of detecting. Further, the method comprises dynamically re-assigning (308) the higher priority and the lower priority amongst the plurality of talk groups, based on detecting activity.
Abstract:
A dynamic call based user ID allows subscriber units to be shared amongst a plurality of users or used for a plurality of roles/uses. A voiced call sign is transmitted by a calling subscriber unit to a targeted subscriber unit. A pattern in the voice transmission of the calling unit is detected, and the voiced call sign is compared to a list of pre-stored call signs. When a match between stored calls signs and the current call sign occurs, the calling subscriber unit saves the current call sign. Fixed network equipment (FNE) then associates the saved current call sign with a subscriber unit ID (SUID) of the calling unit. The dynamic association between the call sign and the SUID allows the subscriber unit to be shared amongst different users and for different uses/roles.
Abstract:
A method and apparatus for communicating amongst two-way radios is disclosed. The method includes operating a two-way radio 130 in either a trunked mode or conventional mode over an operating frequency and scanning an auxiliary channel by the two-way radio 130 to enable radio communication on the auxiliary channel while maintaining the operating frequency active. The radio 130 further detects a signal on the auxiliary channel with another radio 150 and communicating on the auxiliary channel in an intercom mode to provide an intercom radio-to-radio communication amongst all radios 130, 140 scanning on the auxiliary channel.
Abstract:
A display (202) is formed on an OLED layer (210) and at least one other layer formed of different display technology (212). At least one sensor (206 and/or 208) is used to determine a condition which impacts readability of the display (202). The different display layers are enabled and disabled in response to the sensed conditions to provide optimum viewing.
Abstract:
A pressure activated remote microphone is provided within a communication system (100). A face mask (102) incorporates a remote microphone (118) and one or more pressure sensor(s) (122). When a user puts on the mask (102), the remote microphone (118) is enabled in response to the pressure sensed by the pressure sensors (122). When the mask (102) is removed, the remote microphone (118) is disabled in response to the change in pressure sensed by the pressure sensor(s) (122).
