Abstract
A method, device, and system for scheduling a status update in a time division multiple access (TDMA) communication system. One method includes transmitting, with a call controller, scheduling information to the each of the plurality of communication devices via an outbound time slot associated with a control channel of a local common TDMA channel to schedule the each of the plurality of communication devices to transmit the status data in a pre-determined sequence. The method also includes receiving the status data from at least one of the plurality of communication devices in the pre-determined sequence.
Claims17
A method for scheduling transmission of status data from each of a plurality of communication devices in a time division multiple access (TDMA) communication system, the method comprising:
- transmitting, with a call controller, scheduling information to the each of the plurality of communication devices via an outbound time slot associated with a control channel of a local common TDMA channel to schedule the each of the plurality of communication devices to transmit the status data in a pre-determined sequence via a remote common channel, wherein the remote common channel is separate from the local common TDMA channel;
- and
- receiving the status data from at least one of the plurality of communication devices in the pre-determined sequence via a remote inbound time slot of the remote common channel that is synchronized with an inbound time slot of the local common TDMA channel.
A method for scheduling transmission of status data from each of a plurality of communication devices in a time division multiple access (TDMA) communication system, the method comprising:
- transmitting, with a call controller, scheduling information to the each of the plurality of communication devices via an outbound time slot associated with a control channel of a local common TDMA channel to schedule the each of the plurality of communication devices to transmit the status data in a pre-determined sequence;
- receiving the status data from at least one of the plurality of communication devices in the pre-determined sequence;
- and
- transmitting, with the call controller, adjusted scheduling information to the each of the plurality of communication devices via the outbound time slot associated with the control channel of the local common TDMA channel to schedule the each of the plurality of communication devices to transmit the status data in a second pre-determined sequence in response to not receiving the status data from the each of the plurality of communication devices in the pre-determined sequence, the second pre-determined sequence being different than the pre-determined sequence.
A portable communication device comprising:
- communication circuitry configured to communicate with a call controller;
- and
- an electronic processor communicatively connected to the communication circuitry, the electronic processor configured to
- receive scheduling information from the call controller via an outbound time slot associated with a control channel of a local common time division multiple access (TDMA) channel;
- and
- transmit status data during an inbound time slot based on the scheduling information received from the call controller;
- and
- a positioning transceiver,
- wherein the status data includes location data determined by the positioning transceiver.
A time division multiple access (TDMA) communication system comprising:
- a call controller including
- an electronic processor configured to
- transmit scheduling information to each of a plurality of communication devices via an outbound time slot associated with a control channel of a local common TDMA channel to schedule the each of the plurality of communication devices to transmit status data in a pre-determined sequence, and
- receive the status data from at least one of the plurality of communication devices in the pre-determined sequence, and
- wherein one of the plurality of communication devices includes
- a portable communication device including a device electronic processor configured to
- receive the scheduling information from the call controller, and
- transmit the status data via a remote inbound time slot of a remote common channel synchronized with an inbound time slot the local common TDMA channel.
