PROBLEM TO BE SOLVED: To provide a method for providing telecommunication services, and a switching node, a service control node and a switching system for executing the same method. SOLUTION: A service switching function(SSF) which a control device (CONTR) of a switching node (SSP) executes is operated by a call demand from a line subscriber (A) of a telecommunication network (T-NET), a service demand message is transmitted to a service control function (LSCF1), and the service control function (LSCF1) controls provision of the telecommunication services. The control device (CONTR) of the switching node (SSP) transfers the demand message to a LAN. A system platform (SPL1) of the control device (CONTR) of the switching node (SSP) and system platforms of service control nodes (LSCP1 and LSCP2) are connected in this LAN.
