Method for transmitting data, particularly having multimedia contents, in a mobile radio telephone network
View Patent ↗A method is provided for transmitting data, particularly having multimedia contents, from a first communications unit to a second communications unit ( 40; 114 ) in a telephone communications network, whereby at least one transmission status message assigned to the data is transmitted to the first communications unit. In the event that data cannot be delivered to the second communications unit, an item of information concerning a non-deliverability of the sent data is provided in the transmission status message.
1. A method for operating a switching arrangement for handling data having multimedia content transmitted from a first communications unit to a second communications unit in a communications network, the method comprising:
transmitting a message to the second communications unit indicating that the data is ready for downloading;
determining, in the event that the data has not been delivered to the second communications unit, a non-delivery reason from at least two reasons, wherein the at least two reasons are
that the switching arrangement could not deliver the data to the second communications unit and
that the data could be delivered to the second communications unit but was not received by the second communication unit; and
transmitting a transmission status message to the first communications unit, the transmission status message indicating, based upon the determining, said non-delivery reason;
wherein the determining a non-delivery reason from at least two reasons further comprises determining that the switching arrangement could not deliver the data to the second communications unit when an acknowledgement from the second communications unit of the message indicating that the data is ready for downloading was not received by the switching arrangement.
2. The method of claim 1 , wherein the data is transmitted via a Multimedia Messaging Service using a Wireless Application Protocol.
3. A method for operating a switching arrangement for handling data having multimedia content transmitted from a first communications unit to a second communications unit in a communications network, the method comprising:
transmitting a message to the second communications unit indicating that the data is ready for downloading;
determining, in the event that the data has not been delivered to the second communications unit, a non-delivery reason from at least two reasons, wherein the at least two reasons are
that the switching arrangement could not deliver the data to the second communications unit and
that the data could be delivered to the second communications unit but was not received by the second communication unit; and
transmitting a transmission status message to the first communications unit, the transmission status message indicating, based upon the determining, said non-delivery reason;
wherein the determining a non-delivery reason from at least two reasons further comprises determining that that the data could be delivered to the second communications unit but was not received by the second communication when an acknowledgement from the second communications unit of the message indicating that the data is ready for downloading was received by the switching arrangement and the data was not retrieved by the second communications unit prior to the end of a validity period.
4. The method of claim 3 wherein the period of validity is transmitted by the first communications unit to the switching arrangement.
5. The method of claim 3 , wherein the data is transmitted via a Multimedia Messaging Service using a Wireless Application Protocol.
6. A method for operating a switching arrangement for handling data having multimedia content transmitted from a first communications unit to a second communications unit in a communications network, the method comprising:
transmitting a message to the second communications unit indicating that the data is ready for downloading;
determining, in the event that the data has not been delivered to the second communications unit, a non-delivery reasons from at least two reasons, wherein the at least two reasons are
that the switching arrangement could not deliver the data to the second communications unit and
that the data could be delivered to the second communications unit but was not received by the second communication unit; and
transmitting a transmission status message to the first communications unit, the transmission status message indicating, based upon the determining, said non-delivery reason;
wherein the determining a non-delivery reason from at least two reasons further comprises determining that the data could be delivered to the second communications unit but was not received to the second communication unit when an acknowledgement from the second communications unit of the message indicating that the data is read for downloading was received by the switching arrangement and an acknowledgment of receipt of the data was not received from the second communications unit.
7. The method of claim 6 , wherein the data is transmitted via a Multimedia Messaging Service using a Wireless Application Protocol.
