Abstract
An instruction to enter a scanning mode may be received at a communication device. The communication device may participate in several talkgroups. A determination may be made that at least one of the talkgroups is active. In response, the communication device may be set to a first active talkgroup. A determination may be made that a predetermined time has passed since the communication device was set to the first active talkgroup. In response, a determination also may be made that at least a second one of the talkgroups, other than the first active talkgroup, is active. In response, the communication device may be set to the second active talkgroup.
Claims20
A method, comprising:
- receiving, at a communication device, an instruction to enter a scanning mode, the communication device permitted to participate in a plurality of talkgroups;
- receiving, at the communication device, control channel information;
- wherein the control channel information includes respective aggregate lengths of time that a plurality of other communication devices have been in a dedicated transmission mode;
- in response to receiving the instruction to enter the scanning mode, determining that at least a first one of the plurality of talkgroups is active, using the control channel information;
- in response to determining that at least one of the plurality of talkgroups is active, setting the communication device to a first active talkgroup of the plurality of talkgroups;
- determining that a predetermined time has passed since the communication device was set to the first active talkgroup;
- in response to determining that the predetermined time has passed since the communication device was set to the first active talkgroup, determining that at least a second one of the plurality of talkgroups, other than the first active talkgroup, is active;
- and
- in response to determining that the second talkgroup is active, setting the communication device to the second active talkgroup of the plurality of talkgroups.
A communication device permitted to participate in a plurality of talkgroups, the communication device comprising:
- one or more processors, wherein the one or more processors are configured to:
- receive an instruction for the communication device to enter a scanning mode;
- receive control channel information;
- wherein the control channel information includes respective aggregate lengths of time that a plurality of other communication devices have been in a dedicated transmission mode;
- in response to receiving the instruction to enter the scanning mode, determine that at least one of the plurality of talkgroups is active using the control channel information;
- in response to determining that at least one of the plurality of talkgroups is active, set the communication device to a first active talkgroup of the plurality of talkgroups;
- determine that a predetermined time has passed since the communication device was set to the first active talkgroup;
- in response to determining that the predetermined time has passed since the communication device was set to the first active talkgroup, determine that at least a second one of the plurality of talkgroups, other than the first active talkgroup, is active;
- and
- in response to determining that the second talkgroup is active, set the communication device to the second active talkgroup of the plurality of talkgroups.
A non-transitory, computer-readable medium configured to store computer-readable instructions that, when executed by a processing device, instruct the processing device to perform a method comprising:
- receiving, at a communication device, an instruction to enter a scanning mode, the communication device permitted to participate in a plurality of talkgroups;
- receiving, at the communication device, control channel information;
- wherein the control channel information includes respective aggregate lengths of time that a plurality of other communication devices have been in a dedicated transmission mode;
- in response to receiving the instruction to enter the scanning mode, determining that at least one of the plurality of talkgroups is active using the control channel information;
- in response to determining that at least one of the plurality of talkgroups is active, setting the communication device to a first active talkgroup of the plurality of talkgroups;
- determining that a predetermined time has passed since the communication device was set to the first active talkgroup;
- in response to determining that the predetermined time has passed since the communication device was set to the first active talkgroup, determining that at least a second one of the plurality of talkgroups, other than the first active talkgroup, is active;
- and
- in response to determining that the second talkgroup is active, setting the communication device to the second active talkgroup of the plurality of talkgroups.
