<p>The present invention discloses a time obtaining method and apparatus, and a mobile terminal, and belongs to the field of mobile terminals. The method includes: receiving, by a mobile terminal, a time obtaining request, and determining whether the mobile terminal has access to a network service; initiating, by the mobile terminal, an emergency call when the mobile terminal has no access to a network service; receiving a sync channel message which is obtained through searching during the emergency call process and terminating the emergency call, where the sync channel message carries time information; and obtaining time according to the time information. In the present invention, in a situation where time synchronization needs to be implemented and a mobile terminal has no access to a network service, the terminal initiates an emergency call and implements network search during the emergency call process, so as to obtain first signaling, that is, a sync channel message, for interacting with the network during the network search process. Once obtaining the sync channel message, the terminal immediately terminates the initiated emergency call process, extracts time information carried in the sync channel message, and obtains time according to the time information, thereby obtaining time from a network side without affecting other services.</p> |
