The serving node receives an initialization message from the UE and determines a call reference number for the incoming call. An incoming call listener is activated to listen to incoming calls that are related to the call reference number. A signal is created which listens for a trigger-signal in basic functions in the basic code module. After the incoming call, related to the call reference number is detected, the signal listener is allocated to the incoming call, wherein an application in the programming module is executed after the signal listener detects the trigger signal related to the call reference number. ## Claims ### Claim 1 A method of supporting a communication established between a mobile terminal (UE), and a serving node of a telecommunication network, the serving node comprising an application interface for receiving and sending messages to the UE, a programming module adapted to store and process applications, and a basic code module adapted to store and process basic functions of the serving node, wherein the serving node performs the following method steps: receiving an initialization message from the UE at the application interface and determining a call reference number for the succeeding incoming call, activating an incoming call listener to listen for incoming calls, related to the call reference number, creating a signal listener, which listens for a trigger-signal in the basic functions, after the incoming call listener detects an incoming call related to the call reference number, allocating the signal listener to the incoming call, executing an application in the programming module after the signal listener detects a trigger-signal in the basic functions related to the call reference number, and determining whether to block execution of a basic function in the serving node related to the call reference number during execution of the application in the programming module. ### Claim 2 (depends on 1) The method according to claim 1, wherein after the application interface receives an initialization message from the UE, an application, triggered by the application interface, is executed to create a signal listener and to trigger basic functions in the basic code module. ### Claim 3 (depends on 1) The method according to claim 1, wherein the call reference number is an international mobile subscriber identity, IMSI. ### Claim 4 (depends on 1) The method according to claim 1, wherein after the activation of the incoming call listener, the serving node further performs the following steps: starting a call timer associated with the call reference number, deactivating the incoming call listener which is related to the specified call reference number, when the call timer expires before the incoming call listener detects an incoming call related to the specified call reference number. ### Claim 5 (depends on 1) The method according to claim 1, wherein the application interface sends or receives data to or from the UE initiated by the application running in the programming module or in the UE. ### Claim 6 (depends on 1) The method according to claim 1, wherein the initialization message comprises a delay indication for the serving node to delay the deactivation of an incoming call listener. ### Claim 7 (depends on 1) The method according to claim 1, wherein a signal adapter translates data sent between the application of the programming module and the basic function of the basic code module. ### Claim 8 (depends on 1) The method according to claim 1, wherein every incoming call from another serving node is checked by a B-number listener in the terminating serving node which triggers an application inside the programming module. ### Claim 9 (depends on 1) The method according to claim 1, wherein before an initialization message is received by the serving node, a negotiation between the UE and the serving node is performed to check the ability of the serving node to handle the application of the UE. ### Claim 10 (depends on 9) The method according to claim 9, wherein the negotiation comprises the steps of: sending a request to the serving node by the UE, wherein the request comprises a service-identity, checking if an according application is implemented in the free programming module of the serving node, and sending a result to the UE by the serving node indicating the availability of the application in the serving node. ### Claim 11 (depends on 1) The method according to claim 1, wherein determining whether to block execution of the basic function in the serving node related to the call reference number depends on data from the initialization message. ### Claim 12 A serving node, comprising: a basic code module, adapted to store and process basic functions of the serving node;
