Title: Method for restrictiing outgoing call of subscriber in exchange system
Inventor: HUH HAENG SUK
IPC: H04M3/42
Filed: 2000-07-06
Abstract: PURPOSE: A method for limiting outgoing calls in a switching system is provided to limit an outgoing call for a registered code only, even in case that a subscriber calls a number within the limitations of available prefixes. CONSTITUTION: If a subscriber connected to a subscriber ASS(Access Switch Subsystem) attempts a call, an ASP(Access Switch Processor) sets a search pointer(search_ptr) to "1", assigns a limit code flag value(ac_flag) to "Bxxxxxxxxxx" and initializes a search result(search_sts) as "unknown"(400). The ASP receives one destination digit and stores it in a register(cd_dgt)(402). After increasing a destination digit counter(cd_dgt_cnt) by "1"(404), the ASP checks whether the destination digit counter(cd_dgt_cnt) reaches the number of prefixes(406). If the destination digit counter(cd_dgt_cnt) is more than the number of prefixes, the ASP searches for a limit code(408). Then the ASP checks the search result(search_sts)(410). If the search result(search_sts) is "search_OK", the ASP sends a call limit announcement(418). If the search result(search_sts) is "search_NOK", the ASP processes the call normally(420). If the search result(search_sts) is "unknown", the ASP checks whether the destination digit counter(cd_dgt_cnt) is the maximum digit(max_dgt)(412). If the destination digit counter(cd_dgt_cnt) is smaller than the maximum digit(max_dgt), the ASP receives the next destination digit, stores it in the register(cd_dgt), and increases the destination digit counter(cd_dgt_cnt) by "1"(414,416).
