Vehicle and method for controlling emergency call of the vehicle

A vehicle comprising:

• a navigation device including a controller and providing a navigation service;
• and
• a telematics unit enabling wireless communication with the vehicle, wherein
• the controller acquires network coverage information of a plurality of communication networks, stores the network coverage information for each link in a map of the navigation device, calculates at least one parameter for selecting a communication network needed to maintain continuity of an emergency call signal generated by the vehicle when an emergency call button of the vehicle is manipulated, selects a communication network needed to maintain continuity of the emergency call signal based on the at least one calculated parameter, and connects the emergency call signal through the selected communication network,
• the at least one parameter is at least one of:
• a network electric field value of a current position of the vehicle, a numerical value of a network coverage map, a travel direction of the vehicle, and an average speed of the vehicle, and
• the controller selects a communication network having a non-zero numerical value of the network coverage map.

A method for controlling an emergency call signal generated from a vehicle, the method comprising:

• acquiring network coverage information of a plurality of communication networks;
• storing the network coverage information for each link in a map of a navigation device installed in the vehicle;
• calculating at least one parameter for selecting a communication network needed to maintain continuity of the emergency call signal when an emergency call button of the vehicle is manipulated;
• selecting a communication network needed to maintain continuity of the emergency call signal based on the at least one calculated parameter;
• connecting the emergency call signal through the selected communication network;
• and
• regenerating the emergency call signal when a telephone conversation resulting from the emergency call signal is interrupted,
• wherein the at least one parameter is at least one of:
• a network electric field value of a current position of the vehicle, a numerical value of a network coverage map, a travel direction of the vehicle, and an average speed of the vehicle, and
• wherein the selecting of the communication network needed to maintain continuity of the emergency call signal comprises selecting a communication network having a non-zero numerical value of the network coverage map.
