According to at least one of embodiments of the present invention, the present invention includes receiving a transport stream from a broadcasting network, accessing a mobile communication network or a the broadcasting network to receive a broadcast service guide, if a broadcast service guide is receivable, receiving and displaying the broadcast service guide, and if 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. ## Claims ### Claim 1 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 multiplex configuration 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 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). ### Claim 2 (depends on 1) The mobile terminal of claim 1, wherein when the broadcast service guide is not receivable, the controller scans a prescribed broadcast frequency band of the broadcasting network until being tuned to a random broadcast frequency and then extracts the broadcast control information from the transport stream of the tuned broadcast frequency. ### Claim 3 (depends on 1) The mobile terminal of claim 1, wherein the controller controls reception and playback possibility information on each broadcast service to be displayed together with the broadcast service identity information. ### Claim 4 (depends on 1) The mobile terminal of claim 1, wherein after the broadcast service identity information has been displayed, when the broadcast service guide is receivable, the controller controls the broadcast service identity information to be updated into the received broadcast service guide. ### Claim 5 (depends on 1) The mobile terminal of claim 1, wherein after the broadcast service identity information has been displayed, when the broadcast service guide is receivable from the mobile communication network, the controller displays an alarm indicating that the broadcast service guide is displayable and then controls the broadcast service guide to be displayed according to a selection made by a user. ### Claim 6 (depends on 3) The mobile terminal of claim 3, wherein before the broadcast service identity information is displayed, the controller attempts to sequentially receive all broadcast services provided by the broadcasting network and then controls reception and playback possibility information on each of the broadcast services to be displayed together with the broadcast service identity information. ### Claim 7 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). ### Claim 8 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).
