Description

ISDN D-channel data transfer

description

The invention relates to methods and devices for the transmission of useful information via a channel of a telecommunications network to a terminal of a terminal user

During Internet use, useful information can be transmitted in a wide variety of ways. Useful information is transmitted in particular via SMTP as e-mail or via HTTP or XTP as graphic information or graphical control instructions. In addition to user information expressly requested by the terminal user, other useful information, such as advertising information (for example transmitted as a banner advertisement) or references to other screen pages (hyperlinks) via the control channel. Especially when transmitted via HTTP or XTP, the graphic information is already relatively compressed ♦

The aim of the invention is to transmit useful information as efficiently as possible via the control channel or logical connection to a terminal of a terminal user. The object is solved in each case by the subject matter of the independent claims

The invention allows a wide variety of useful information to be transmitted via the signaling channel of a telecommunications network. In particular in Germany, this is done according to the invention, for example, via the D channel of an ISDN network, since this with the signaling information usually transmitted via it with regard to its available bandwidth of 16 kBit / sec not is fully utilized. Thus, according to the invention, narrowband services in particular can be implemented by useful information transmission. Useful information according to the invention can be, for example, stock exchange information, traffic information, advertising information, indications of screen rare elements (hyperlinks), other information or combinations thereof

In addition to the D channel, it is of course also possible in each case to use signaling channels of other transmission technologies, for example in other fixed network transmission methods such as ADSL or in other geographic areas standardized transmission methods with the respective ones provided there

Signa sations channels take place

A signaling channel according to claim 1 can also be any logical channel

Appropriate coding of useful information is advantageously carried out on the network side in order to enable a differentiation of the useful information on the terminal device side from signaling information likewise transmitted via the signaling channel, for example by transmitting signaling information in certain timeslots and / or with certain identifiers (for example service identifier / logical connections)

The method on the terminal device can be implemented, for example, with a modem on or in a computer

Further features and advantages of the invention result from the claims and the following description of an exemplary embodiment with reference to the drawing

Procedure by switching off the terminal or an application on the terminal

Figure 1 shows a terminal user 1, the computer 2 with a keyboard 3, a

Housing 4, a modem card 5 provided in the housing 4, a screen 6 and speakers 7 8 is provided. The modem 5 of the computer is connected to a telecommunications network in the form of an ISDN network. For this purpose, the modem 5 can be connected, for example, via a conventional ISDN connection device and if necessary, intermediate adapter to be connected to an ISDN connection socket 9 of the terminal user. The connection socket is connected to the ISDN network. From the ISDN connection socket 9 of an ISDN user, useful information 19 and signaling information 13 of the terminal user or for the terminal user are sent to or from the user in the usual manner Telecommunications network operators transmit This can be done physically, for example, by two copper wire pairs The illustrated terminal user 1 has two useful information channels 10, 11 and one signaling channel (= D channel) 12 as an ISDN connection, in which case he calls for example with one useful information channel 10 and over the other

1 1 can surf the Internet or can also surf the two user information channels 10, 1 1 can surf the Internet via the signaling channel 12 (D channel in ISDN)

Signaling information 13 transmitted between the telecommunications network and the terminal of the terminal user. According to the invention, useful information 14 is also transmitted to the terminal user 1 on this signaling channel 12, since the bandwidth of this signaling channel is generally not completely exhausted. Therefore, one is in the telecommunications network 15

A device (16) is provided for the telecommunications network operator (in addition to components not shown, such as packet switches, gateways, etc.), which carries out the coupling of useful information according to the invention into the signaling channel on the telecommunications network side. This device 16 can be provided at a suitable point in the telecommunications network

In the present example, the computer 2 is physically connected to the telecommunications network. The user channels are idle (= are not currently being used). According to the invention, the device 16 transmits user information 14 from a provider 20 via the signaling channel 12 (between the transmission of signaling data 13 there) takes place in a suitable coordination with the end device, for example in certain timeslots or through certain headers, by hardware and / or software adaptation in the end device etc

For example, certain information 14 can be transmitted for all users

It is also possible for a terminal user to select special information desired by the device 16 and via the signaling channel

12 are transmitted as user information 14, such as certain stock exchange information, traffic information, selected advertising, etc

FIG. 2 illustrates as a block diagram that a user (via a modem (not shown)) on his terminal 2 can surf (at least) one B-channel and one Internet service provider 22 on the Internet 18 while he is using the D-channel for useful information (14) received from a provider 16, which can also get this from the Internet 18, for example. According to FIG. 2, useful information is transmitted as UUS messages or display messages via the D channel.

The conventional Internet access via the (at least one) B channel 10 and the

Internet provider 22 is set up, operated and dismantled via D channel 12 independently of the reception (or transmission) of useful information 14. However, an Internet connection can be activated by a software application regarding the reception of user information 14 via the D channel, for example via a software button, via the B channel 10.

From the device 16, customer-specific information (such as, in particular, the number of e-mails received for the user of the terminal 2) and / or broadcast information (= broadcast information), such as news tickers, weather information, etc. for all users or certain user groups are sent out. With regard to the broadcast information, a selection of useful information 14 for certain users can take place in the device 16 on the basis of their previous selection or / and location information about the user (on the basis of digits in the area code and / or telephone number).

As FIG. 3 shows, a central server can be used on the provider side for all user information including user-specific user information (such as messages via emails and email texts) 16. In this case, all useful information is forwarded from the device 16 via a D channel to the EWSD, via a central signaling channel to a further EWSD and from there via a D channel 12 to the user of the terminal 2. The advantage of this solution is that that only one central server is used.

According to FIG. 4, a central server 24 can alternatively only be used for certain useful information, in particular only for terminal-specific useful information, such as messages via emails and / or email texts (with a signaling as in FIG. 3) and additionally several locally distributed servers 25 for other content as user information is available. This relieves the ZGS-7 network

FIG. 5 shows an overview of the implementation of the method according to the invention on the network side (with the designation near AODI in FIG. 5), with several groups of terminal devices (2,5) each being connected to ISDN via EWSD 26 to 30. The EWSD 26 to 30 are connected an ISDN signaling system No 7 (reference numeral 27) connected

FIG. 6 shows an example of a graphical representation of user information on the screen of a terminal. In several windows 31 to 35, certain groups of user information are shown, namely in window 31 weather information, in window 32 user information relating to new e-mails for the user

Users of the terminal, in the window 33 useful information regarding current news, in the window 34 stock exchange information and in the window 35 sports information. It is also possible to activate the dial-in of the terminal (2.5) via B-ISDN channels via the button 36

Since certain useful information, such as in particular information about e-mails for a specific user, is secret, such useful information is only transmitted after the user or terminal device has been authenticated to a mail server etc. of the provider. This can be done in particular by one or two UUS information elements take place, which in particular can contain the phone number and / or a password and are transmitted from the user terminal to a server of the provider

After authentication, user information (14) relating to a user's e-mails is sent to the user. For this purpose, a polling process cyclically checks the e-mails.

Mail accounts of all active users (dialed in according to the invention via a D channel) If unread e-mails and / or new e-mails are present for a user, the user is informed by user information (via UUS 1) Two servers, i.e. an e-mail server and a broadcast server, can be used to manage the e-mails and send user information to a user. In this case, the e-mail server informs the associated broadcast server, as soon as a user is active (dialed in according to the invention via the D channel) The user is then also considered active in the broadcast server and broadcast information is sent to the user

Broadcast information can be sent in particular as so-called display information via the D channel via the DSS1 protocol. A customer-specific selection of broadcast information can be stored in his customer profile, after which the customer only has selected broadcast information (e.g. only weather - information) received

Regardless of the signaling according to the invention via the D channel, a user can at any time connect to his Internet via one or two B channels.

Establishing the ISP service provider The Internet service provider can also belong to the same provider. It can also be integrated with a server of the provider, in particular with the provider's mail server

When a user switches off his terminal, ends an application program according to the invention or switches off his modem, etc., the D-channel connection is disconnected. In this case, the broadcast server is informed by the mail server that the user is no longer in the active status and sets the delivery of the information to this user at the latest after a specified time interval, the broadcast server sets a user to the status

"Inactive", unless the mail server sends information that this user is still active. The mail server regularly polls the status of all users and informs the broadcast server

The customer disconnects the connection to the mail server

Termination of the client applications on his end device A poll is carried out cyclically on the mail server, which leaves the status of the client as "active" when the client application responds. In the other case, the client is set as "inactive" and the corresponding one Broadcast server informed of the inactive status of the client 7 shows the nighttime flow when a client logs on to the mail server.

Fig. 8 shows the cyclical night flow during a session (with registration via the D channel and receipt of an e-mail.

FIG. 9 shows the nighttime flow when the software application according to the invention is ended on a terminal.

EWSD in the figures denotes any digital switching device, e.g. the digital electronic dialing system from Siemens AG.
