Abstract:
checking whether a route automatic control function is registered when a routing request is received; if it is registered, automatically controlling a traffic of a specific outgoing route according to a control class; if a trunk seizure release message of the specific outgoing route is received, checking whether a route automatic control function is registered, and if it is registered, changing an automatic control state of the specific outgoing route, thereby raising a call completing rate even at an abnormal traffic state.
Abstract:
trying to seize a trunk when a routing request is received, checking whether a re-routing function and a re-route are registered when there is no idle trunk; if they are registered, checking a restrictive method; and controlling a traffic by a re-routing function during call processing according to a direct route and a round about route, thereby reducing load even at an excessive traffic state.
Abstract:
The method is for controlling the number of service for a certain subscriber by using programmable service category. The method comprises the steps of: (A) forming data base for each subscriber which restricts the boundary of enable service function for each subscriber; (B) discriminating that the received prefix is a service-enable phone number to a transmitter; (C) discriminating that the received phone number is a service-enable phone number to a transmitter; and (D) changing category if necessary.
Abstract:
The method is for supervising timer table according to incoming calls so that interprocessor communication data loss is prevented. The method comprises the steps of: (a) translating incoming phone number by a number translating block (NTR,8) in a number translating processor (NTP,5); (b) generating incoming call occupation request signal by the NTR (8); (c) sending an incoming call occupation request signal to an analog subscriber control (ASC) (10) and driving a timer; (d) processing the incoming call according to the response signal from the ASC (10) and when no response signal is detected retrying the step (c) through another unoccupied line; and (e) processing the incoming call as failure after retrying the step (c) and (d) for a certain time.
Abstract:
The method employs an ASS (3) which executes the call process of matching devices, time switch, and signal devices, an INS (2) which executes space switching, number translation, and routine functions, a CCS (1) which executes a operation, maintenance statistics, management of hard disk and input-output devices. The method includes the 1st step which includes a linked list structure of database; the 2nd step which decides a prefix in the system, in analyzing a line state and line categories; the 3rd step which analizes prefix, notifies result, and decides call success; and the 4th step which processes call process by the analyzing result.
