US 2019/0095422 A1 · WORD-BY-WORD TRANSMISSION OF REAL TIME TEXT

Abstract

A first user equipment (UE)—during a real time text (RTT) communication session with a second UE—may be configured to transmit RTT content in “word mode” by buffering text characters in local memory as they are typed by a user, and holding off on transmitting the buffered text characters until the user types a word delimiter or a timer expires, whichever occurs first. In an example process, the first UE may detect character user input requesting to type a text character, and, in response, the first UE starts a timer and buffers the text character in local memory. The timer can be restarted for additional text characters that are typed before expiration of the timer, and those additional text characters are also buffered. The buffered text characters are transmitted upon detecting delimiter user input requesting to type a word delimiter or the expiration of the timer, whichever occurs first.

Dependent claims

A first user equipment (UE) comprising:

a processor;
an input device;
a network interface;
and
memory storing computer-executable instructions that, when executed by the processor, cause the first UE to, during a real time text (RTT) communication session:
detect, via the input device, character user input requesting to type a text character;
in response to detecting the character user input, start a timer that is to expire after a period of time if no additional user input is detected;
buffer the text character in the memory as a buffered text character;
detect, via the input device and prior to expiration of the timer, delimiter user input requesting to type a word delimiter;
and
in response to detecting the delimiter user input prior to the expiration of the timer, send, via the network interface, and over a telecommunications network to a second UE involved in the RTT communication session, one or more RTT packets carrying the buffered text character, wherein the one or more RTT packets are sent without user intervention, at a predetermined frequency.

A method to be implemented by a first user equipment (UE), the method comprising, during a real time text (RTT) communication session:

detecting, via an input device of the first UE, character user input requesting to type a text character;
in response to the detecting of the character user input, starting a timer that is to expire after a period of time;
buffering the text character in memory of the first UE as a buffered text character;
determining that the timer has expired without detecting additional user input via the input device;
and
in response to the determining that the timer has expired without detecting additional user input, sending, via a network interface of the first UE, and over a telecommunications network to a second UE involved in the RTT communication session, one or more RTT packets carrying the buffered text character.
