Claim 0:
1. A method of preventing call drop in a voice communication network, the method comprising:
receiving, by a first terminal and a second terminal, a first indication that the first terminal is entering a low-signal area when a session is established for a voice call initiated between the first terminal and the second terminal;
disabling, by the first terminal and the second terminal, respective one or more media inactivity timers based on the first indication for retaining the session;
storing, by the first terminal and the second terminal, one or more network parameters associated with the first terminal when one of, the session is retained and when the session is released;
receiving, by the first terminal and the second terminal, a second indication that the first terminal has exited the low-signal area; and
when the session is retained, resuming, by the first terminal and the second terminal, the voice call on the session based on the stored network parameters upon enabling the respective one or more media inactivity times based on the second indication;
when the session is released, re-initiating, by the first terminal and the second terminal, the voice call on a new session based on the stored network parameters based on the second indication.
