Abstract

Embodiments herein provide a method and system of responding to a call with a text. The method includes receiving by a target communication device a call from an initiator communication device. The target communication device responds to the from call with a real time text (RTT). One or more characters in the RTT are sent instantaneously to the initiator communication device.

Claims

1. A method of responding to a call with a text by a target communication device, the method comprising:

receiving a call from an initiator communication device;

receiving, from the initiator communication device, information for the call in case that the target communication device does not answer the call during a predetermined time interval;

transmitting, to a network, a first message including a real time text (RTT) tag, the first message indicating support of a RTT of the target communication device;

receiving, from the network, a second message including the RTT tag, the second message indicating support of the RTT of the initiator communication device; and

responding to the call with the RTT based on the information for the call and the second message, wherein at least one character entered by the target communication device in the RTT is displayed instantaneously on the initiator communication device.

2. The method of claim 1, wherein responding by the target communication device to the call with the RTT comprises:

accepting the call received from the initiator communication device, wherein the call is accepted independent of establishment of a call session; and

responding to the call with the RTT after accepting the call, wherein the RTT is sent to the initiator communication device when call is on hold.

3. The method of claim 1, wherein responding by the target communication device to the call with the RTT comprises:

rejecting the call from the initiator communication device; and

responding to the call with the RTT.

4. The method of claim 1, wherein responding by the target communication device to the call with the RTT comprises:

accepting the call received from the initiator communication device, wherein the call is accepted independent of establishment of a call session;

responding to the call with the RTT after accepting the call, wherein the RTT is sent to the initiator communication device when call is on hold for a time interval; and

unholding the call with the initiator communication device.

5. The method of claim 1,

wherein the call is one of:

a voice call, or a video call,

wherein the voice call is one of;

a circuit switched (CS) call, or

a packet switched (PS) call, and

wherein the video call is a PS video call.

6. The method of claim 1, wherein the target communication device receives the call with the RTT from the initiator communication device.

7. A target communication device configured to:

receive a call from an initiator communication device;

receive, from the initiator communication device, information for the call in case that the target communication device does not answer the call during a predetermined time interval;

transmit, to a network, a first message including a real time text (RTT) tag, the first message indicating support of a RTT of the target communication device;

receive, from the network, a second message including the RTT tag, the second message indicating support of the RTT of the initiator communication device; and

respond to the call with the RTT based on the information for the call and the second message, wherein at least one character entered by the target communication device in the RTT is displayed instantaneously on the initiator communication device.

8. The target communication device of claim 7, wherein the target communication device is further configured to respond to the call with the RTT by:

accepting the call received from the initiator communication device, wherein the call is accepted independent of establishment of a call session; and

responding to the call with the RTT after accepting the call, wherein the RTT is sent to the initiator communication device when call is on hold.

9. The target communication device of claim 7, wherein the target communication device is further configured to respond to the call with the RTT by:

rejecting the call from the initiator communication device; and

responding to the call with the RTT.

10. The target communication device of claim 7, wherein the target communication device is further configured to respond to the call with the RTT by:

accepting the call received from the initiator communication device, wherein the call is accepted independent of establishment of a call session;

responding to the call with the RTT after accepting the call, wherein the RTT is sent to the initiator communication device when call is on hold for a time interval; and

unholding the call with the initiator communication device.

11. The target communication device of claim 7,

wherein the call is one of:

a voice call, or

a video call,

wherein the voice call is one of;

a circuit switched (CS) call, or

a packet switched (PS) call, and

wherein the video call is a PS video call.

12. The target communication device of claim 7, wherein the target communication device is further configured to receive the call with a RTT from the initiator communication device.

13. An initiator communication device configured to:

transmit a call from an initiator communication device,

transmit, to a target communication device, information for the call in case that the target communication device does not answer the call during a predetermined time interval;

receive, from a network, a first message including a real time text (RTT) tag, the first message indicating support of a RTT of the target communication device;

transmit, to the network, a second message including the RTT tag, the second message indicating support of the RTT of the initiator communication device; and

initiate the call with the target communication device by including the RTT in the call, wherein at least one character entered by the target communication device in the RTT is displayed instantaneously on the initiator communication device.

14. The initiator communication device of claim 13, wherein the initiator communication device is further configured to initiate the call after receiving a RTT from the target communication device.

15. The initiator communication device of claim 13,

wherein the call is one of:

a voice call, or

a video call,

wherein the voice call is one of;

a circuit switched (CS) call, or

a packet switched (PS) call, and

wherein the video call is a PS video call.

16. A non-transitory computer readable storage medium configured to store one or more computer programs including instructions that, when executed by at least one processor, cause the at least one processor to control for:

receiving a call from an initiator communication device;

receiving, from the initiator communication device, information for the call in case that a target communication device does not answer the call during a predetermined time interval;

transmitting, to a network, a first message including a real time text (RTT) tag, the first message indicating support of a RTT of the target communication device;

receiving, from the network, a second message including the RTT tag, the second message indicating support of the RTT of the initiator communication device; and

responding to the call with the RTT based on the information for the call and the second message, wherein at least one character in the RTT is sent instantaneously to the initiator communication device.

17. A method of initiating to a call with a text by an initiator communication device, the method comprising:

transmitting a call from an initiator communication device;

transmitting, to a target communication device, information for the call in case that the target communication device does not answer the call during a predetermined time interval;

receiving, from a network, a first message including a real time text (RTT) tag, the first message indicating support of a RTT of the target communication device;

transmitting, to the network, a second message including the RTT tag, the second message indicating support of the RTT of the initiator communication device; and

initiating the call with the target communication device by including the RTT in the call, wherein at least one character entered by the target communication device in the RTT is displayed instantaneously on the initiator communication device.

18. The method of claim 17, further comprising:

initiating the call after receiving the RTT from the target communication device.

19. The method of claim 17,

wherein the call is one of:

a voice call, or

a video call,

wherein the voice call is one of;

a circuit switched (CS) call, or

a packet switched (PS) call, and

wherein the video call is a PS video call.
