Abstract: The invention relates to a method for filtering messages in an instant method system for mobile terminals, said system including an instant message server managing the exchange of messages between clients provided with mobile terminals and other users, said method being characterised by the fact that, upon reception of a message intended for the mobile terminal of a client, the message server directly analyzes said received message and: if the analyzed message contains a sequence of characters corresponding, after comparison, to a specific sequence, the instant message server transmits such message to the mobile terminal of the client, if the analyzed message does not contain this sequence of characters, the instant message server bars this message.

Abstract: The invention aims to reduce the number of computer applications to be integrated in a mobile terminal in order to implement the functionalities offered to a user: IM, MAIL, BLOG, etc. The invention also aims to simplify the communication networks, the exchanges between mobile terminals and source servers, and also the management of formats. A communication network comprises at least one mobile terminal (TM) designed to receive information in a target format, and source servers (SS1, SS2, SS3, SS4) designed to deliver information in source formats. According to the invention, an intermediate server (SPV), which is independent of the source servers (SS1, SS2, SS3, SS4), is arranged between the mobile terminal (TM) and said source servers so that the information destined for said mobile terminal passes via the intermediate server. The intermediate server (SPV) is designed to receive information in the source formats from the source servers (SS1, SS2, SS3, SS4).

Abstract: The invention relates to an instantaneous messaging system for mobile terminals comprising one or several instantaneous messaging service servers (S1, S2) able to deliver instantaneous messaging services to mobile terminals (TA, TB1, TC1, TD1, TB2, TE2, TF2) connected to said servers and of which the users (A, B1, C1, D1, B2, E2, F2) have opened an instantaneous messaging session, and a virtual presence server (100) independent of the existing instantaneous messaging service servers (S1, S2), said virtual presence server being connected to at least one mobile client terminal (TA) and to at least one of the existing messaging servers (S1, S2) in such a way that the information intended for or sent by said mobile client terminal transits by said virtual presence server, wherein the instantaneous messaging service servers (S1, S2) are configured to transmit contact lists intended for mobile client terminal (TA), said lists being intercepted by the virtual presence server (100), the latter comprising a means to a

Abstract: The invention relates to an instantaneous messaging system for mobile terminals comprising one or several instantaneous messaging servers (S1, S2) able to deliver instantaneous messaging services to mobile terminals (TA, TB1, TC1, TD1, TB2, TE2, TF2) connected to said servers and of which the users (A, B1, C1, D1, B2, E2, F2) have opened an instantaneous messaging session, and a virtual presence server (100) independent of the existing instantaneous messaging servers (S1, S2), said virtual presence server being connected to at least one mobile client terminal (TA) and to at least one of the existing messaging servers (S1, S2), wherein said virtual presence server (100) comprises means to automatically manage an instantaneous messaging session in place of said user (A), said means of management being activated when the connection between said mobile client terminal (TA) and said virtual presence server is cut off.

Abstract: This invention relates to a method for exchanging requests between the computer application of a mobile terminal (A) and an instantaneous messaging server (1), wherein: the computer application sends requests (2) to server (1) relative to the detection of an event (3), requests (2) are sent according to a request frequency set to a first value, whereby: when requests (2) are sent, if the event (3) is not detected by server (1), said server controls the computer application so that the latter sends the requests (2) according to a request frequency set to a second value that is lower than the first value, as soon as server (1) detects the event (3), said server controls the computer application so that the latter sends the requests (2) according to a request frequency set to the first value.

Abstract: The invention relates to a method for sending content from a mobile sending device belonging to an originator to at least one receiving device associated with a respective recipient, characterised in that it includes steps in which: Said mobile sending device sends said content to a storage server; Said storage server stores said content, associating a content identifier with it; Said storage server builds a content page including said content, said content page being associated with a first address, said first address depending at least on said content identifier; Said storage server sends said mobile sending device a first message including a second address associated with a recipient-selection page; Said mobile sending device accesses said recipient-selection page by means of said second address; Said originator builds, by means of said recipient-selection page, a list including an identifier of said receiving device; Said server sends said receiving device a second message including at least said first
