Description

The invention relates to a method for administration of subscribers / operators of a telecommunications network, who are members of an operator service, the network owns several exchanges.

So-called operator services are required in telephone networks which is an essential link between customers of the network and the network operators. The task ben of such an operator service are varied, one The main task is to turn participants off on request to issue future. For example, a participant can have one Call the operator service in an ISDN network and get information solicit. The operator responsible can now, if necessary, e.g. B. access a database, then a Information about another participant in the picture screen of his PC. After a connection request from the Operator who e.g. B. can be done by pressing a button Operator connected to the searched subscriber. The operator is now with both the original participant and the sought subscriber and can optionally with a the participant speak. Another key press there is a signaling on the D channel, and now are the connection locations of both participants of the peripheral connection announce group, and the connection of voice channels takes place via the coupling network, so that ultimately a direct There is a connection between the two participants. The The example just described is just one of the ways or represent tasks of an operator service.

Large networks with many subscribers require correspondingly large operator service systems with many, mostly hierarchically structured system subscribers (operators), such as, for example, in the applicant's system called ADMOSS. As already mentioned, the operators report to a switching center in an ISDN network in the D channel, in a point-to-point configuration with permanently active layer 2 of the OSI layer model. The messages are made in an ISDN network supported by the D-channel protocol, including the Blue Book, Volume VI - Fascicle VI. 11, "Digital Subscribe Signaling System No. 1 (DSS1), Network Layer, User-Network Management", Recommendations Q. 930-Q. 940, in particular reference is made to Recommendation Q. 931.

The operators are usually in so-called call centers stationed, and their respective from end device, PC, screen etc. usually existing and in the following "console" said facility is directly connected to the system or connectable to the local exchange. always more often, however, there is a need to decentralized ope rators, for example in the context of homework, however, a single central administration system for the Operators in the network may be possible.

Accordingly, it is an object of the invention to provide a network-wide administration of all operators and consoles of the To enable operator system. For example, a central exchange - called the master's office - the Infor mation which operators are free or occupied or are out of order, so that, for example, a request from a Network subscriber regarding a telephone number, address etc. quickly to an operator of a remote exchange can be forwarded if no operator of the local Switch is available. So it should be a network-wide call distribution regarding the operators possible his.

This task is performed using a method of the type mentioned at the beginning Type solved in which according to the invention after logging in Operator at his home exchange in a data channel  and successful login by the operator via the data channel to the peripheral connection group of the operator a request for remote login in a central master office is sent, a phone number or phone number table vir current participant from the peripheral line group is sent to the operator who Operator using the phone number or phone number belle a call to a virtual operator initiated, and with successful establishment of the conversation via an interoffice signaling the request for Remote login from the home exchange to the master office sent and in this its coordination processor is forwarded, then log-on confirmation data and for the operator service specific data from the coordination processor and / or a peripheral connection group of the Ma in the peripheral connection group of the operator in the home exchange and from there to the terminal of the operator, and a status message from the Operator over a data channel to the peripheral connector group of home placement and from here via an intermediate Office signaling to the coordination processor of the Masteram is sent.

Thanks to the invention, a network-wide and central managed operator system can be created.

It can be convenient because resources can be saved if after the Remote logging of the operator to the master office the local log to the home placement office.

To facilitate operator work, it can be provided that that the status message only after the expiry of the success rich remote logon the following protection period is sent.

It is useful if the data to be transferred is from the peripheral connection group via a data channel to the part Participants will be sent, this being the usual and required  The possibility of data also exists in the network represents transmission.

On the other hand, since, according to the invention, a talk ver is built, it can also be useful if the data to be transferred using a data link program transmitted over the established communication channel.

The invention is particularly suitable for use in one ISDN network, the data channel being the D channel and the Ge voice channels are B channels. Then the intermediate Office signaling can be an ISUP signaling.

The invention together with further advantages is based on the following an exemplary embodiment with the aid of Drawing explained in more detail. This shows in its only one Figure the basic structure of a network with two Darge provided switching centers and an operator service.

In the figure you can see some participants OP1, OP2,. , , an operator service, whereby here not on the hierarchy within the participants OP1, OP2,. , , is received. All participants OP1, OP2,. , , are TEI of a telecommunications network NET, in the present case an ISDN network, in addition to conventional power supply units, and are therefore integrated into the network via an S ₀ interface, that is to say connected to a network connection NDE here.

A first exchange VS1 of the network is shown at the top right, and it has a switching network SNE and peripheral line groups LTG, LTC connected to it in a known manner. To control the switching center VS1, especially the switching network SNE, a coordination processor COP is provided. Likewise, in a known manner, each peripheral line group LTG, LTC contains a group processor GRP, and concentrators DLU (digital line unit) are connected to each peripheral line group in this _exemplary embodiment via a U _k0 interface. Each of these DLU concentrators also has several inputs for the network connections already mentioned. In the case of larger switching centers, up to 512 peripheral line trunk groups LTG (Line Trunk Group), LTC can be connected to a switching network SNE, and two concentrators DLU are usually connected to each line trunk group LTG. In a known manner, the peripheral connection groups LTG, LTC also contain a so-called group switch GSI.

In a peripheral line trunk group LTG, LTC run different programs run by the group processor GRP under are supported, e.g. B. here is the largest part of the verb development, signaling, code reception, etc. Im generally 70% of the connection establishment in the peri pheren extension groups carried out, whereas the coordination onprocessor COP especially routing tasks.

An "operation and Maintenance system "OMS with an" Operation and Maintenance Terminal "OMT, on the surveillance personnel the state of the Monitor the exchange constantly and identify errors can.

The participants OP1, OP2,. , , Operator services usually have workstations with personal computers that contain ISDN cards and special software, as well as headsets for the operators. The end points of the operators are also called "consoles" in the following. On the part of the participants OP1, OP2,. , , messages can be sent to the switching center, especially to the peripheral line trunk groups LTG, these messages being processed in the group processor GRP and for corresponding further measures, e.g. B. lead a connection. The messages are sent in a point-to-point configuration with permanently active layer 2 and in an ISDN network in the D channel.

In the drawing at the bottom right, a further exchange VS2 belonging to the network NET is drawn, the structure of which corresponds in principle to that of the first exchange VS1, but the second exchange VS2 serves as the master office of the operator service. Of course, depending on the size of the network, there may be many other exchanges, as indicated here only by two boxes VS3, VS4. Each of these exchanges can again be assigned to operators OP _x , OP _y .

Each exchange VS1, VS2,. , , has a special peripheral line trunk group LTC for fast data connections, which in the context of inter-office signaling z. B. the ISUP signaling (see, for example, BP Bocker, ISDN - digital networks for voice, text, data, video and multimedia communication , 4th edition, Springer, Section 6.2.9 , "interim signaling) the data exchange with other such connection groups via rapid data connections, e.g. fiber optic lines.

For the invention it is essential that a registration in hereinafter also referred to as "login", each operator OP1, OP2,. . . possible at a remote office, here the master office VS2 is. The invention now sees one described in more detail below procedure.

A participant or operator OP1 answers first - the State of the art - using a passport word and an ID number at his home exchange le VS1. After successful login, the Kon sole of the operator OP1 via a data connection in the D channel a request for remote logon in the VS2 master office to the associated peripheral connection group LTG of the home exchange sent to VS1. This requirement now leads to that a phone number or a phone number table is more virtual Operators VO1, VO2 are sent to the console of the operator OP1 becomes.  

Such virtual operators are in at least one peri set up the LTG master group of the VS2 master's office, and are required for an actual call to be able to build.

The console of the operator OP1 then uses the number or one of the possible numbers for a call dung, d. H. a connection in a B channel to a virtual len operator VO1. After successfully building this The request for remote login is made via the connection Intermediate signaling from the exchange of the Participant OP1 sent to and in the master office VS2 forwarded to the coordination processor COP. In the next Step become so-called "log-on-response" data and call number data, such as system time and date, the Hierarchy structure, personal data and different Permissions, such as access to statistics cal data, etc. from the coordination processor COP and / or a peripheral connection group LTG of the master office VS2 in the peripheral line group LTG of the operator OP1 - in the Home exchange VS1 - or from here to the operator console loaded. This can be done via a data channel (D channel) or via the existing call connection in a B channel with the help of a Data Link program. After finishing This data transfer is related to the "local" Log-on between operator OP1 and home exchange VS1 "Log-Off" initiated.

However, if the call connection in the B channel between Operator console and virtual operator VOP failed has come, the mentioned number table on the part the console the next number of a virtual operator removed and a new connection attempt started.

After successful log-on in the master's office VS2, expediently after the expiry of a certain  Protection time implemented by a post-call timer a status message (Operator Status Message) in this "Idle" case, from the console of the operator OP1 via a D- Channel connection to the peripheral line trunk group LTG Home placement VS1. From here, the Zwi official signaling, e.g. B. as mentioned ISUP, the Statusmel transfer (here "idle") to the master office VS2 and here sent to the coordination processor COP. The one mentioned Protection time of, for example, 20 to 60 s leaves the connection of the operator OP1 still appear to be occupied and should prevent the operator OP1 practically at the same time with his log-on is "overfilled" by a request.

Status changes of the operator OP1, e.g. B. from "idle" "busy" are treated in the same way and are therefore in the Master's office VS2 known.

The invention enables one in the manner described above network-wide operator service system, in which because of the a central administrative office (exchange) tion of the system, for example, operators in remote offices the work of the system can be integrated.
