Patent ID: 8472959

Claim:
A communication control system, comprising: one or more processors configured to: detect a handover in which a communication terminal present in a communication area formed by a base station moves from the communication area to a communication area formed by another base station; acquire, if the handover is detected, information based on the handover for use in codec switching for switching a codec applied to communication currently performed by the communication terminal; detect a communication scheme in communication performed between the communication terminal and the another base station; detect another communication scheme performed by another communication terminal on another end communicating with the communication terminal; select a codec after switching based on the acquired information and based on a communication scheme having lower quality between the communication scheme and the another communication scheme; and apply the selected codec to the communication currently performed, wherein the one or more processors are further configured to sense a probability of call loss in a communication network to which the another base station connects and detect a load status in the communication network based on the sensed probability of call loss.
