Abstract

Monitoring theIN call traffic is difficult due to the fact that legal regulations allow the monitoring function to be integrated only to public telephone exchanges and that an incoming call is often identified only in a IN computer (SCP). The invention solves that problem according to a method whereby the SCP communicates to the monitoring VST the identification number of a monitored IN subscriber during an IN call.

Description

The method of monitoring IN calls

In order to exchange according to customer requirement conversion telecommunications, public junction network utilizes a central database (IN computer=service control point SCP) more and more continually.To this, identification (mostly by means of telephone number) in IN visit exchange (service exchange point SSP), the enforcement inquiry, and generally be the network address significant, that this calling will be sent to the replying of IN of this inquiry.Relay computer is not partly understood for the people that will constitute connection, because calculate (for example universal personal Telecommunication UPT, 2 VPN (virtual private network) VPN) by IN computer actuating logic and expense.

Practical problem:

Country's regulations (Deutsche Telecom's regulations (TKG § 88) for example, in Europe, token vote case 17.01.1995, the law case of communication aspects, or in the U.S.: CALEA is used for the communications assistance 1994 of law compulsion action, public law 103414; 47 USC 101-1010) requirement can be monitored each telecommunications exchange, and monitoring IN exchange.At this, according to other jural public exchange (Vst) the unified monitoring function that is defined in.

Go wrong in the combination of afore mentioned rules, even only implement the identification to the people of conversion calling on the IN computer, that is to say does not have the Vst of notice by chance to utilize which IN client.If should monitor so IN client, then the IN customer ID must be intercepted from speech channel in junction network, because only where there are these information.

Therefore, do not monitor at present or do not exchange by the unified solution monitoring IN of network.

Propose in new IN-SW scheme, the result of monitoring (label as a result) directly is transferred to demand carrier (for example police) from IN computer (SCP).

Though, must be transferred to the Vst that will monitor to the lot of data amount from IN computer (SCP) if also monitored the communication exchange that when calling out, takes place.Perhaps database and the hardware configuration of preparing for label output is indispensable.Owing to can realize the IN inquiry of similar all exchange exchanges of a network, so this will cause, data are transferred to Vst (by standard agreement INAP) from the IN computer under the monitoring situation, and have prepared all essential configurations in all Vst in advance.The repeatedly storage of monitor data and secret these data of processing and only these data are deposited with predesignating on a small amount of selected point in the network and contradict.

Therefore following problem appears in present solution:

1.) IN computer (SCP) must be stored very lot of data, perhaps is the special data of the Vst producer, and is transferred to the Vst (SSP) that wants inquiry when needed;

2.) undesirable open placement (the Vst producer is special) of monitor data library structure is because the SCP producer must adjust and store these data;

3. be essential), that is to say, greatly delayed reaction, and can standardization other function expand (for example passing through Siemens) hardly new demand by using the long-term world agreement of standardized Intelligent Network Application Protocol (between SCP and SSP);

4.), in all SSP, have and predesignate and adjust X.25 terminal preparatively for data output.

The present invention is based on this task, a method is described, avoid the problems referred to above by this method.

Solve this task by method according to claim 1.

The invention has the advantages that,

-transmit a spot of data to SSP from SCP,

-only implement monitoring function among a spot of, the selected Vst in network, and therefore only where make certain preparation (database/hardware configuration),

If-in network, except that monitoring function, there is not SSP (the old scheme or the other producer's SSP), can certainly monitor the IN exchange.Change original IN by the pre-Vst that determines calls out for this reason.

Elaborate the present invention by means of accompanying drawing below, wherein accompanying drawing comprises two figure.

The method according to this invention is, when calling out, IN in a SCP, determines, whether should monitor one and participate in the IN user that IN calls out, for an IN user that will monitor, call an exchange, be so-called monitoring exchange, implement real monitoring, directly or spacing (by IN visit exchange) the notice monitoring exchange IN user's that will monitor identification number by SCP by this exchange.From monitor database, find out the data (Jian Kong form for example, demand carrier ...) of monitoring explanation by means of identification number monitoring exchange, implement to monitor accordingly by means of this monitoring phone office of these data.

Basic advantage of the present invention is, only transmits a spot of data (feature " monitoring ", the IN user's that monitor identification number (IN user calling and/or called)) to the exchange that will monitor from the IN computer.

Set forth with two selectable forms of implementation.

Select 1:

In SCP, IN user of mark (perhaps its identification number) is monitoring.If this user's of supply inquiry from any SSP of network at this moment, then SCP offers the monitor message that SSP finds out from partner's call number (IN business), be monitoring features, the IN user's that monitor a identification number and a possible transmission call number (call number of network-critical for the long-distance user).SSP analyzes these information, the monitoring of articulating in IN calls out connects, and the watch-dog (long-distance user) of these information providings (perhaps according to SCP information (long-distance user's transmission call number), or by using the selection of the transformed profile realization Vst among an existence and the SSP) in the Vst of a selection.IN calling originally as there not being monitoring function to handle, that is to say without any influence in SSP.

Realize monitoring the other operation and the control (referring to Fig. 1) of connection by the remote client in selected Vst.

Select 2:

An IN user (perhaps its identification number) is labeled as monitoring in SCP, that is to say, stores in SCP, should monitor this IN user.If this user's of supply inquiry from any SSP of network at this moment, then SCP starts the transmission of calling out originally in a pre-Vst who determines, adjusts the surveillance and control measure (delivering of the monitored IN calling on the pre-Vst that determines) of this calling in this Vst.On this SSP, be implemented in the articulating (referring to Fig. 2) that the monitoring in the IN calling connects.Not only can but also can realize the other IN control that original IN calls out by first SSP by second SSP, if in a SSP, keep control, then under (setting forth below in addition) precondition of determining, in having the Vst of monitoring function, can end the 2nd IN communication.

Elaborate by means of the professional UPT of special IN below and select 2,, in monitoring Vst, monitor and control wherein as starting point.

Sight 1:

The party A-subscriber selects an IN number, carries out an IN inquiry in the Vst of source, and does not provide the network address (as real inquiry) of UPT user as " replying " SCP, but source Vst causes the calling that is transformed into an other SSP.Therefore, at this moment where can the real calling of proper operation, SCP must attach provides one " special calling number ", and this call number causes desirable action in the 2nd SSP.To this, should " special calling number " constitute by two parts, promptly a reference address and the IN to monitoring SSP triggers number, that is to say the business signature number of UPT user." special calling number " is transferred to the 2nd SSP from source SSP, and where cause an IN inquiry again, wherein, at this moment SCP is by means of number combination " reference address+UPT number " identification, from monitor message, find out, at this moment the network address of UPT user must be provided.At this moment transmit original IN and call out, because this calling of control in monitoring Vst, so also can where monitor (in this sight, it predesignates one the 2nd IN inquiry, also can abandon the transfer of monitor message in first inquiry).

Sight 2:

The party A-subscriber selects an IN (UPT) call number.Carry out an IN inquiry in the Vst of source, and also provide additional digital as " replying " SCP except that monitor message and UPR user's the network address, it causes, originally Call Transfer to an other SCP.Therefore at this moment where real calling can be accurately operated, conversion portion must be removed again in front, the network address.Control this removal once again by an IN inquiry, or handle (in the 2nd SSP) by a Vst internal code and control this removal.That is to say that " the special calling number " that be provided for SCP in sight 2 constitutes (in this sight, it does not predesignate the 2nd IN inquiry, and monitor message is delivered in first inquiry) by the network address of translation number+UPT user.

Example scenarios 1:

-party A-subscriber selects: 01837 242424=UPT call number

-SCP provides the conversion call number: 089 9,999 1837 242424=special calling numbers

-with 089 9999 in the local phone net of Munich Vst of control, and where complete special number is transferred to

-in the 2nd SSP call number 089 9,999 1,837 242424 cause a repetition to the IN inquiry of the network address of UPT user (having UPT call number 01,837 242424) and monitor

At this moment-SCP provides the real network address (network address=04047114711) of UPT user.

-the two SSP transmits this IN to hamburger with the network address 040 47114711 and calls out to UPT user.

Example scenarios 2:

-party A-subscriber selects: 01837 242424=UPT call number

-SCP is provided at the conversion call number of the front, the network address of UPT user: 089 99990401 14711=special numbers

-call number 089 9,999 04047114711 causes the IN inquiry of a repetition in the 2nd SSP, wherein where only remove 089 9999, or call number changes to 04047114711 through 089 9,999 04047114711 code process in conversion Vst.Additional identification and implement this measure in monitoring.

-the two SSP transmits this IN to hamburger with 040 47114711 and calls out to UPT user.
