Abstract: PURPOSE: A method for improving functions of a programmable switch in a service node is provided to receive a service function concentrated in the programmable switch, to make the service node progress a normal service with the service function perceived in the programmable switch when an error is generated in the host controller, so as to improve system reliability and to simplify the structure of the host controller to reduce costs. CONSTITUTION: A service node forms a transmission path between a programmable switch and resource processors, to directly transmit messages to the resource processors from the programmable switch(S1). The service node adds a service scenario function which is a function of a host controller to the programmable switch(S2). The service node periodically performs link tests between the programmable switch, the resource processors, and the host controller to decide reciprocal states(S3). If the decided states are normal, the service node transmits incoming information to the host controller, to make a normal service progress through the resource processors(S4). If the states are not normal, and if the host controller does not perform a normal operation, caused by an error, the programmable switch operates a service scenario instead of the host controller and transmits direct service starting information to the resource processors, to perform a normal service(S5).

Abstract: PURPOSE: A method for controlling the ringer tone volume level of a portable phone is provided to prevent a user from missing a call by automatically increasing the ringer tone volume level when an incoming call is received. CONSTITUTION: A control unit checks whether an incoming call is received(201). If the incoming call is received, the control unit outputs a ringer tone to the external by controlling a ring signal generation unit(202). If a called subscriber inputs a call formation key(203), the control unit forms a one-way call path between the calling side and the called side(204). If it is judged whether the call formation key was not inputted, the control unit counts a ringer tone generation time(205). If it is judged that the ringer tone generation time exceeds a preset time, the control unit increases the ringer tone volume level(206) and generates the ringer tone at the increased ringer volume level(207). The control unit judges the volume level of the ringer sound(208). If it is judged that the level is maximum, the control unit judges whether the call formation key was inputted within a preset ringer tone generation time(209). If it is judged that the call formation key was inputted within the preset time, the control unit forms the call path(210).
