Method and apparatus for initiating communication modes

摘要

Aspects of the subject disclosure may include, for example, a method for receiving, by a system comprising a processor, a first request to transition a communication device between a hearing mode and a teletype mode, and transmitting, by the system, a SIP command to a telecommunication network to switch between registration and deregistration of the communication, where the SIP command is transmitted responsive to expiration of a period for disabling switching between the registration and the deregistration. Other embodiments are disclosed.

主权项

1. A communication device comprising:
a memory to store executable instructions; and a processor communicatively coupled to the memory, wherein the processor, responsive to executing the executable instructions, performs operations comprising:
receiving an input from a user interface requesting a transition from a hearing mode to a teletype mode;generating a first session initiation protocol (SIP) command for switching from registration to deregistration of the communication device at a telecommunication network responsive to the input and to an expiration of a first disable registration period, wherein the first SIP command initiates deregistration of the communication device when transitioning from the hearing mode to the teletype mode;determining whether a second disable registration period has been started;initiating the second disable registration period responsive to the second disable registration period not having been started, wherein the second disable registration period is based on a length of time required for the telecommunication network to switch between the registration and the deregistration of the communication device;determining whether the second disable registration period has expired responsive to the second disable registration period having been started;transmitting the first SIP registration command as a first request to the telecommunication network to switch from the registration to the deregistration of the communication device responsive to the second disable registration period having expired; andtransitioning from the hearing mode to the teletype mode according to a response from the telecommunication network.
