Method of invocation, in a terminal (T), of at least one application service (S1, S3) by a browser (NAV), said method comprising: - a step (E40) of detection, in a first page (TAB2) loaded in said browser (NAV), of at least one invocation datum (DN, DN2) according to at least one type (TY1, TY2) of invocation datum stored for said at least one service (S1, S3); and - a step (E60) of invocation, in said loaded first page (TAB2), of said at least one service (S1, S3) on the basis of said at least one detected invocation datum (DN), said method being characterized in that it comprises, prior to the detection step (E40), a step (E10) of reception of a first instruction (INS1) defining at least one second page (TAB1, TAB3) providing said at least one service (S1, S3), said first instruction (INS1) defining said at least one type (TY1, TY2) of invocation datum, a network address pointing to at least one third page (TAB1', TAB3') and an invocation function of said at least one service (S1, S3); said invocation step (E60) comprising: o a step of initiation of the download of said at least one third page (TAB1', TAB3') on the basis of said at least one address; and o a step of invocation of said function; said method comprising a step (E80) of execution of said at least one service (S1, S3) in said at least one third page (TAB1', TAB3'), said execution step comprising execution of said function, causing display, in said loaded first page (TAB2), of a control unit (UNIT) that may be accessed by a user with a view to controlling said at least one service (S1, S3) during its execution in said third page (TAB1', TAB3'). - a step (E40) of detection, in a first page (TAB2) loaded in said browser (NAV), of at least one invocation datum (DN, DN2) according to at least one type (TY1, TY2) of invocation datum stored for said at least one service (S1, S3); and - a step (E60) of invocation, in said loaded first page (TAB2), of said at least one service (S1, S3) on the basis of said at least one detected invocation datum (DN), said method being characterized in that it comprises, prior to the detection step (E40), a step (E10) of reception of a first instruction (INS1) defining at least one second page (TAB1, TAB3) providing said at least one service (S1, S3), said first instruction (INS1) defining said at least one type (TY1, TY2) of invocation datum, a network address pointing to at least one third page (TAB1', TAB3') and an invocation function of said at least one service (S1, S3); said invocation step (E60) comprising: o a step of initiation of the download of said at least one third page (TAB1', TAB3') on the basis of said at least one address; and o a step of invocation of said function; o a step of initiation of the download of said at least one third page (TAB1', TAB3') on the basis of said at least one address; and o a step of invocation of said function; said method comprising a step (E80) of execution of said at least one service (S1, S3) in said at least one third page (TAB1', TAB3'), said execution step comprising execution of said function, causing display, in said loaded first page (TAB2), of a control unit (UNIT) that may be accessed by a user with a view to controlling said at least one service (S1, S3) during its execution in said third page (TAB1', TAB3'). <EOS>
