Abstract: The invention relates to a method and a device for forwarding short messages from a transmitter (24) to a target number of a receiver (26) in GSM/UMTS mobile radio networks, wherein the target number of the receiver (26) is replaced by a forwarding call number before establishing routing information required for delivery of the short message in a service node (10) and delivery of the short message to the forwarding call number is carried out.

Abstract: A method for synchronizing data related to a communication event between a first mobile device and a second mobile device includes modifying a first data element stored in the first mobile device using a processor of the first mobile device in response to a user action event related to the communication event. The first data element and the modified first data element are related to the communication event. A synchronization message is generated using the processor of the first mobile device, where the synchronization message is related to the modification of the first data element. The synchronization message is transmitted from the first mobile device to the second mobile device. The synchronization message is received and handled using the processor of the second mobile device so as to modify a second data element stored in the second mobile device so as to provide a modified second data element. The modified second data element corresponds to the modified first data element.

Abstract: A method for forwarding multimedia messages in a public land mobile network using a core network with a unit providing a multimedia message forwarding function, includes storing, in a forwarding information database, a multimedia message forwarding information related to forwarding, to a second international mobile subscriber identity, of multimedia messages directed to a first international mobile subscriber identity. The public land mobile network, receives a request for a delivery of a mobile terminated multimedia message to the first international mobile subscriber identity.
