Mobile terminal that displays obtained broadcast service identity information when broadcast service guide is not available and method of controlling mobile terminal

A method of controlling a mobile terminal, the method comprising:

• receiving a transport stream from a broadcasting network;
• accessing a mobile communication network or the broadcasting network to receive a broadcast service guide;
• when the broadcast service guide is receivable, receiving and displaying the broadcast service guide;
• and
• when the broadcast service guide is not receivable, extracting broadcast control information from the transport stream, obtaining broadcast service identity information on a broadcast service provided by the broadcasting network from the extracted broadcast control information, and then displaying the obtained broadcast service identity information,
• wherein the broadcast control information comprises network configuration information of the broadcasting network and multiplex configuration information,
• wherein the method further comprises:
• receiving information on all broadcast frequencies provided by the broadcasting network from the network configuration information;
• and
• obtaining the broadcast service identity information provided by each of the broadcast frequencies from the multiplex configuration information,
• wherein the broadcasting network follows MBBMS (mobile broadcast business management system) broadcasting specification,
• wherein the network configuration information comprises NIT (network information table), and
• wherein the multiplex configuration information comprises CMCT (continual service multiplex configuration table).

A mobile terminal comprising:

• a broadcast receiver configured to receive a transport stream from a broadcasting network;
• a display configured to display a broadcast image;
• and
• a controller configured to access a mobile communication network and, when a broadcast service guide is receivable via the broadcasting network or the mobile communication network, receive and display the broadcast service guide,
• wherein the controller is further configured to, when the broadcast service guide is not receivable, extract broadcast control information from the transport stream, obtain broadcast service identity information on a broadcast service provided by the broadcasting network from the extracted broadcast control information, display the obtained broadcast service identity information,
• wherein the broadcast control information comprises network configuration information of the broadcasting network and carrier frequency information,
• wherein the controller receives information on all broadcast frequencies provided by the broadcasting network from the network configuration information and controls the broadcast service identity information provided by each of the broadcast frequencies to be obtained from the carrier frequency information,
• wherein the broadcasting network follows MBBMS (mobile broadcast business management system) broadcasting specification,
• wherein the network configuration information comprises NIT (network information table), and
• wherein the carrier frequency information comprises CSCT (continual service configuration table).
