| 20160150495 | LOCATION INFORMATION REGISTRATION METHOD AND MOBILE COMMUNICATION TERMINAL - Location information of a mobile communication terminal is registered promptly. When the mobile communication terminal receives a first location registration response signal, in which a predefined value indicative of a cause of rejecting the registration of the location information is set, the mobile communication terminal transmits a location registration request signal to a second mobile communication network when there is the second mobile communication network over which the mobile communication terminal can communicate, based on the predefined value. When it is determined that there is not the second mobile communication network or the location registration of the mobile communication terminal in the second mobile communication network is not completed, the mobile communication terminal carries out a first location registration operation of retransmitting the location registration request signal to the first mobile communication network. | 05-26-2016 |
