Abstract: PURPOSE: A method for broadcasting a delivery message in a signaling transfer point(STP), is provided to distribute functions for managing an adjacent signaling point(SP) to a signal network management processor and each signal message handling processor, and to transmit a delivery message to an adjacent SP of a signal link satisfying a transmission condition in the each signal message handling processor, so as to prevent a load to the each signal message handling processor and enable the processing of a delivery message for a high capacity SP. CONSTITUTION: A signaling network management unit distributes functions for managing an adjacent signaling point(SP) to a signal network management processor and each signal message handling processor(S41). The signal network management processor confirms whether the state change for a SP is generated(S42). If the state change is generated, the signal network management processor transmits a message requesting the transmission of a delivery message to an inter-processor communication(IPC) processor(S43). The IPC processor broadcasts the message requesting the transmission of a delivery message to each signal message handling processor(S44). The each signal message handling processor selects a self signal link(S45). An adjacent SP corresponding to the selected signal link is acquired(S46). Whether the acquired SP is an adjacent SP to which the delivery message is transmitted(S47). If not, feedback to the S45 is performed to confirm whether adjacent SPs corresponding to every signal link included in the corresponding signal message handling processor are adjacent SPs to which the delivery message is transmitted. If the acquired SP is the adjacent SP to which the delivery message is transmitted, a signal link for routing the delivery message to the adjacent SP is acquired(S48). The delivery message is generated and transmitted to the adjacent SP through the acquired signal link(S49).
