Method, device, and system for transmitting short data during a call hang time hold off period
First Claim
1. A method of transmitting short data during a call hang time hold off period in a wireless communication system, wherein call hang time is a time period in which the voice channel is no longer carrying any voice data from or to any of the mobile stations that were in the active call but during which it is reserved for use only by the active mobile stations that were in the active call to end the call hang time by transmitting, the method comprising:
- during an active call on a voice channel, detecting, at a radio controller, deactivation of a push-to-talk (PTT) input at a transmitting mobile station via an uplink channel portion of the voice channel, identifying a particular mobile station in the wireless communication system in need to transmit short data, and responsively;
causing, by the radio controller, a call hang time hold off request to be transmitted via a downlink channel portion of the voice channel to all mobile stations in the active call instructing the mobile stations to delay call hang time for the active call during a call hang time hold off period; and
causing, by the radio controller, a short data transmission request to be sent to the particular mobile station instructing the particular mobile station to transmit inbound short data during the call hang time hold off period.

Abstract
Short data is transmitted during a call hang time hold off period in a wireless communication system. During an active call on a voice channel, a radio controller detects deactivation of a push-to-talk (PTT) input at a transmitting mobile station (MS) via an uplink channel portion of the voice channel and identifies a particular MS in the wireless communication system in need to transmit short data. Responsively, the radio controller causes a call hang time hold off request to be transmitted via a downlink channel portion of the voice channel to all MSs in the active call instructing the mobile stations to delay call hang time during a call hang time hold off period. The radio controller then causes a short data transmission request to be sent to the particular MS instructing the particular MS to transmit inbound short data during the call hang time hold off period.

12. A radio controller in a radio network, the radio controller comprising:
-
a transceiver; a processor; and a computer readable medium having instructions stored thereon that, in response to execution by the processor, cause the radio controller to perform operations comprising; during an active call on a voice channel, detecting deactivation of a push-to-talk (PTT) input at a transmitting mobile station via an uplink channel portion of the voice channel, identifying a particular mobile station in the wireless communication system in need to transmit short data, and responsively; causing, via the transceiver, a call hang time hold off request to be transmitted via a downlink channel portion of the voice channel to all mobile stations in the active call instructing the mobile stations to delay call hang time for the active call during a call hang time hold off period, wherein call hang time is a time period in which the voice channel is no longer carrying any voice data from or to any of the mobile stations that were in the active call but during which it is reserved for use only by the active mobile stations that were in the active call to end the call hang time by transmitting; and causing, via the transceiver, a short data transmission request to be sent to the particular mobile station instructing the particular mobile station to transmit inbound short data during the call hang time hold off period.

13. A mobile station in a wireless communication system, the mobile station comprising:
-
a transceiver; a push-to-talk (PTT) input; a display; a speaker; a microphone; a processor; and a computer readable medium having instructions stored thereon that, in response to execution by the processor, cause the mobile station to perform a set of operations comprising; during an active call on a voice channel, receiving, via the transceiver and a downlink channel portion of the voice channel, a call hang time hold off request instructing mobile stations participating in the active call to delay call hang time for the active call during a call hang time hold off period, wherein call hang time is a time period in which the voice channel is no longer carrying any voice data from or to any of the mobile stations that were in the active call but during which it is reserved for use only by the active mobile stations that were in the active call to end the call hang time by transmitting; during the call hang time hold off period, refraining from acting upon any detected activation of the PTT input; subsequently receiving, via the transceiver and a downlink channel portion of the voice channel, a normal call hang time resume message sent to all mobile stations in the active call instructing the mobile stations to refrain from further delaying call hang time for the active call; and responsive to detecting an activation of the PTT input during call hang time after receiving the normal call hang time resume message, transmitting, via an uplink channel portion of the voice channel, a request to transmit. - View Dependent Claims (14, 15, 16, 17, 18, 19)
