Abstract:
1. A method for transmitting a multimedia message from a first mobile communication network to a multimedia message receiver that has roamed to a second mobile communication network from the first mobile communication network, the method comprising: a) using a multimedia message server to determine whether the multimedia message receiver has roamed based on location information of the multimedia message receiver when there is a request for multimedia message transmission, wherein the multimedia message server requests a short message server to transmit a first notification message including a roaming indicator and the short message server determines whether the multimedia message receiver has roamed based on location information of the multimedia message receiver; b) when it is determined that the multimedia message receiver has roamed, transmitting a second notification message of a pull method to query whether the multimedia message receiver accepts receipt of the multimedia message, wherein when a multimedia message server receives a reception failure message which indicates a failure of the transmission of the first notification message and which is caused by a roaming of the multimedia message receiver from the short message server, the multimedia message server requests the short message server to transmit the second notification message of the pull method and the short message server transmits the second notification message of the pull method; and c) when a response of receipt of acceptance of the multimedia message is received from the multimedia message receiver, transmitting the multimedia message to the multimedia message receiver.
