The navigation service method includes constructing an emergency area resource including unusable route information related to an emergency area; and receiving trip parameters from multiple applications and transmitting a link, through which the emergency area resource is accessible, to an application, the trip parameter of which includes a request to provide unusable route information related to an emergency area, wherein transmitting the link is configured to transmit a link, through which the same emergency area resource is accessible, to applications that request provision of unusable route information related to the same emergency area. ## Claims ### Claim 1 A method in which a server provides route information related to an emergency area to a terminal that is capable of calculating a route, comprising: constructing an emergency area resource that includes unusable route information related to an emergency area; and receiving trip parameters from multiple applications and transmitting a link, through which the emergency area resource is accessible, to an application, the trip parameter of which includes a request to provide unusable route information related to an emergency area, wherein transmitting the link is configured to transmit a link, through which a same emergency area resource is accessible, to applications that request provision of unusable route information related to a same emergency area wherein a user of the terminal is able to provide unusable route information to the emergency area resource for use by other terminals, wherein the constructing of the emergency area resource includes: constructing the emergency area resource so as to include information about a route expected to be unusable in a future; and transmitting a notification message including an identifier of the information about the route expected to be unusable, when the route expected to be unusable becomes unusable, the identifier of the information about the route expected to be unusable used for updating the unusable route information by the terminal which receives the notification message. ### Claim 2 (depends on 1) The method of claim 1, further comprising: receiving a request to subscribe to a notification service related to the emergency area from an application; and when the unusable route information is updated, notifying the application, which requests subscription to the notification service, of updated unusable route information. ### Claim 3 (depends on 2) The method of claim 2, wherein notifying the application of the updated unusable route information is configured to notify the application of the updated unusable route information when a current position of the application is received from the application is in the vicinity of the emergency area. ### Claim 4 (depends on 2) The method of claim 2, further comprising: when all of routes in the emergency area are restored to usable routes, transmitting a notification message for announcing that all of the routes become usable routes to the application that subscribes to the notification service. ### Claim 5 (depends on 4) The method of claim 4, wherein transmitting the notification message is configured such that the server transmits the notification message and deletes a resource related to the unusable route information and such that the application discards the unusable route information by receiving the notification message for announcing that all of the routes are restored. ### Claim 6 (depends on 2) The method of claim 2, wherein the request to subscribe to the notification service includes a subscription resource that the application creates by setting a notification condition for the notification service. ### Claim 7 (depends on 6) The method of claim 6, wherein receiving the request to subscribe to the notification service is configured to receive the request including the subscription resource in which the notification condition is set such that the application receives updated information about unusable routes only when a current position thereof corresponds to the updated information. ### Claim 8 (depends on 1) The method of claim 1, further comprising: transmitting a location of an emergency area related to the trip parameter to the application when the trip parameter does not include the request to provide unusable route information related to an emergency area. ### Claim 9 A server apparatus for providing route information related to an emergency area to a terminal that is capable of calculating a route, comprising: a communication unit for communicating with the terminal; and a control unit for providing traffic information for a route that is received from the terminal, wherein the control unit is configured to: construct an emergency area resource that includes unusable route information related to an emergency area; receive trip parameters from multiple applications and transmit a link, through which the emergency area resource is accessible, to an application, the trip parameter of which includes a request to provide unusable route information related to an emergency area; and transmit a link, through which a same emergency area resource is accessible, to applications that request provision of unusable route information related to a same emergency area, and wherein a user of the terminal is able to provide unusable route information to the emergency area resource for use by other terminals, wherein the emergency area resource includes information about a route expected to be unusable in a future, wherein the control unit transmits a notification message including an identifier of the information about the route expected to be unusable, when the route expected to be unusable becomes unusable, the identifier of the information about the route expected to be unusable used for updating the unusable route information by the terminal which receives the notification message. ### Claim 10 (depends on 9) The server apparatus of claim 9, wherein the control unit receives a request to subscribe to a notification service related to the emergency area from an application and notifies the application, which requests subscription to the notification service, of updated unusable route information when the unusable route information is updated. ### Claim 11 (depends on 10) The server apparatus of claim 10, wherein the control unit notifies the application of the updated unusable route information when a current position of the application is received from the application that approaches is in the vicinity of the emergency area. ### Claim 12 (depends on 10) The server apparatus of claim 10, wherein, when all of routes in the emergency area are restored to usable routes, the control unit transmits a notification message for announcing that all of the routes become usable routes to the application that subscribes to the notification service. ### Claim 13 (depends on 12) The server apparatus of claim 12, wherein: the control unit transmits the notification message and deletes a resource related to the unusable route information; and the application discards the unusable route information by receiving the notification message for announcing that all of the routes are restored. ### Claim 14 (depends on 10) The server apparatus of claim 10, wherein the request to subscribe to the notification service includes a subscription resource that the application creates by setting a notification condition for the notification service. ### Claim 15 (depends on 14) The server apparatus of claim 14, wherein the control unit receives the request to subscribe to the notification service, the request including the subscription resource in which the notification condition is set such that the application receives updated information about unusable routes only when a current position thereof corresponds to the updated information. ### Claim 16 (depends on 9) The server apparatus of claim 9, wherein the control unit transmits a location of an emergency area related to the trip parameter to the application when the trip parameter does not include the request to provide unusable route information related to an emergency area.
