System of interoperability between MMS messages and SMS/EMS messages and an associated exchange method
View Patent ↗A message system is associated with a message domain which includes a mobile radio network, a message server conforming to a first standard referred to as the Enhanced Message Service and/or Short Message Service standard and/or a message server conforming to a second standard referred to as the Multimedia Message Service standard. The message domain further includes a message gateway which includes a database including a table of message profiles of terminals belonging to the message domain and is able to convert a message sent in accordance with the first standard into a message in accordance with the second standard.
1. A Short Message Service communication method, intended for use in communicating a short message initiated by a first mobile radio terminal which is part of a first message domain, and which is capable of exchanging messages with at least one second mobile terminal which is part of a second message domain, each domain including at least one mobile radio network, one first message server conforming to a first message standard, and/or one second message server conforming to a second, different message standard, wherein:
initiating a message, conforming to said first standard, from said first terminal to at least said second terminal not compatible with said first standard to which said initiated message conforms, but compatible with said second message standard;
transmitting said message by said first message server to a message gateway including a database comprising a table of message profiles of terminals belonging to said second message domain with which said gateway is associated, including said second terminal;
converting said initiated message, conforming to said first message standard, by said message gateway into a message conforming to said second message standard supported by said second terminal;
transmitting the converted message standard by said message gateway to said second message server; and
delivering said converted message standard by said second message server to said second terminal, wherein, when said first message standard is EMS or SMS, said second message standard is MMS, and, when said first message standard is MMS, said second message standard is EMS or SMS; and
wherein said table of profiles contained in said message gateway of said second message domain is updated by sending from said first mobile terminal listed in said table to said message gateway an update of the message including an information element containing the message profile or profiles of said terminal,
wherein said message containing user data including a header including said information element and a data text, wherein said information element includes an identification field followed by a field indicating the length of the data of said information element followed by the data of said information element and said header includes a profile information element whose identifier is associated with the updating of a message profile and whose data indicates the message standard or standards supported by the terminal which initiated said message.
2. An Enhanced Message Service communication method, intended for use in communicating an enhanced message initiated by a first mobile radio terminal which is part of a first message domain, and which is capable of exchanging messages with at least one second mobile terminal which is part of a second message domain, each domain including at least one mobile radio network, one first message server conforming to a first message standard, and/or one second message server conforming to a second, different message standard, wherein:
initiating a message, conforming to said first standard, from said first terminal to at least said second terminal not compatible with said first standard to which said initiated message conforms, but compatible with said second message standard;
transmitting said message by said first message server to a message gateway including a database comprising a table of message profiles of terminals belonging to said initiated message domain with which said gateway is associated, including said second terminal;
converting said initiated message, conforming to said first message standard, by said message gateway into a message conforming to said second message standard supported by said second terminal;
transmitting the converted message standard by said message gateway to said second message server;
delivering said converted message standard by said second message server to said second terminal, wherein, when said first message standard is EMS or SMS, said second message standard is MMS, and, when said first message standard is MMS, said second message standard is EMS or SMS; and
converting said initiated message conforming to said first message standard into a message according to said second message standard by said message gateway of said first domain of the first terminal which initiated said message, said initiated message including the address of said message gateway of said first domain in a header and including an information element indicating that data conforming to said second message standard is included in the data of said initiated message, said conversion of said initiated message including extraction of said data conforming to said second message standard;
wherein said enhanced message including user data includes a header with said information element and a data text, wherein said information element includes an identification field followed by a field indicating the length of the data of said information element followed by said data of said element and said header includes a Multimedia Message Service information element whose identifier indicates the presence of Multimedia Message Service information in said data of said message whose data indicates the length of said Multimedia Message Service information, which includes at least one Multimedia Message Service message header.
