Abstract
A switching apparatus and method are disclosed. The method involves establishing, in response to a call from a caller, a communication path between the caller and a called party, selectively tracing only a CID of the caller, or the CID of the caller while wiretapping a content of the conversation, allocating a wiretap resource when a third communication path is established, and outputting the traced CID, information of the call, and wiretapped communication signals.
Claims24
A switching apparatus for receiving a plurality of subscribers, and establishing a communication path between calling and called ones of the subscribers in accordance with a switching operation thereof, comprising:
- a cross switch internally provided with a caller identification (CID) processor adapted to identify a CID, the cross switch being connected with a plurality of subscriber terminals respectively associated with the subscribers while serving to establish a communication path between calling and called ones of the subscriber terminals in accordance with a switching operation thereof,
- a wiretap resource unit for establishing a communication path enabling a plurality of designated subscribers to communicate simultaneously;
- the subscriber terminals each connected to the cross switch, thereby communicating with the called subscriber terminal;
- an operating terminal unit connected between the cross switch and the wiretap resource unit, the operating terminal unit serving to set the communication path between the calling subscriber terminal and the called subscriber terminal to pass through a selected one of the cross switch and the wiretap resource unit, while serving to monitor and control the entire part of the switching apparatus that was used to pass through the selected one of the cross switch and the wiretap unit;
- a database for storing data on a third communication path allocated and designated for wiretapping of a content on conversation by telephone made in association with a malicious call;
- and
- a wiretap terminal connected to the wiretap resource unit and adapted to wiretap and record the content of conversation by telephone made in association with the malicious call.
4 more elements
A method for processing a malicious call in a switching apparatus having caller identification (CID) and conference call functions, comprising:
- determining a call processing mode set by a called subscriber terminal to trace only a CID of a calling subscriber terminal, or to trace a CID of a particularly designated caller or CIDs of all callers while wiretapping a content of conversation by telephone made by the particularly designated caller or each of the callers;
- if it is determined that the call processing mode is set to trace the CID or CIDs while wiretapping the content of conversation by telephone, then establishing a third communication path for wiretap services, and allocating a wiretap resource to allow the content of conversation by telephone to be wiretapped via the third communication path;
- and
- outputting the wiretapped content of conversation by telephone via the third communication path, releasing the allocated wiretap resource when communications between the called and calling subscriber terminals are completed, and completing the processing of the malicious call.
1 more element
A method for processing a malicious call in a switching apparatus having caller identification (CID) and conference call functions, comprising:
- a communicating step of establishing, in response to a call from a calling subscriber terminal, a communication path between the calling subscriber terminal and a called subscriber terminal, and enabling a communication between the calling and called subscriber terminals via the established communication path;
- a call processing mode determining step of determining whether a call processing mode set by the called subscriber terminal corresponds to a mode for tracing only a CID of the calling subscriber terminal, or a mode for tracing a CID of a particularly designated caller or CIDs of all callers while wiretapping a content of conversation by telephone made by the particularly designated caller or each of the callers;
- a resource allocating step of if it is determined that the set call processing mode corresponds to the mode for tracing the CID or CIDs while wiretapping the content of conversation by telephone, then determining whether or not at least one third communication path for wiretap services is established, and allocating a wiretap resource when it is determined that the third communication path is established;
- a wiretapping step of outputting the CID of the calling subscriber terminal, information about the call generated by the calling subscriber terminal, and a communication signal for wiretap on the third communication path;
- and
- communication completion determining and resource releasing steps of determining whether or not communications between the calling and called subscriber terminals have been completed, and returning to the call processing mode determining step when the communications are continued, while releasing the allocated wiretap resource when the communications have been completed, and returning to a process completing step.
