Configuration and maintenance method for terminal connected to telecommunications network, by transmitting configuration message to terminal based on input data

The Invention relates to a method for configuring and maintenance from above a device interface to a wired telecommunications network tethered landline telecommunication terminal, wherein <ul><li>a) on the part of a service node of the network arising present from him for the landline telecommunication terminal specific useful data at least one configuration message is created, which configuration parameters for the includes landline telecommunication terminal,</li><li>b) produced by the service node a network connection to the landline telecommunication terminal and the at least one configuration message over the network connection to the Landline telecommunication terminals is transmitted, and</li><li>c) the part of the fixed-line telecommunications terminal the Configuration message via the device interface received, at least temporarily stored and the device configuration with respect modified the configuration parameters in the configuration message becomes.</li></ul>

at different tethered to a telecommunications network devices, such as about mobile stations (DECT) or answering machines, is the configuration these devices for the Users about by entering or changing various parameters, For example, concerning the selection mode, Charge information, etc. possible said operating parameters on the device usually by means of a display entered or modified and a command in the form of a keyboard will. By mostly small displays and keyboards of the devices and their limited However, resource is the user guidance not very comfortable, and said speeds possible be very little or not at all used mostly.

Out the document "ISDN office - HICOM "of Siemens AG, 1985 is an in-house ISDN system, consisting of a so-called HICOM server on the subscriber side, different terminals (phones, fax, etc.) can be connected, known. The HICOM server in turn is connected to a public telecommunications network connectable. Further disclosed in this document, on the one hand HICOM server through a public Telecommunications network from an external control panel is maintained remotely, and on the other hand that a "tightening" of features possible participant side is. Under this "tightening" is particularly to understand that user-specific settings for at the HICOM server connected terminal (for example, an individual Keys, etc.) after proper authentication the user may also be used on another terminal, thus this setting from a device connected to the HICOM server terminal can be traced to another connected device.

at this system it is possible, a configuration of a terminal device to transfer the plant to another extension of this facility, so not every device must be specially configured. In addition, in such a System designed and the configuration of a terminal comfortable se will.

For wired terminals, are not part of such a complex and expensive internal Telephone system, is currently a simple and convenient maintenance and however configuration impossible.

To the above-mentioned Procedures similar procedures, for example, from the <patcit><text>GB 2225918 A</text></patcit>. of the <patcit><text>US 5483586 A</text></patcit> or of the <patcit><text>DE 44 08 976 C2</text></patcit> known. Example example is in the <patcit><text>US 5483586 A</text></patcit> an apparatus and a method for updating the phone book of a softphone an operator of a local On-line phone directory described.

disadvantageous is the method previously known from this prior art, however, that a simple configuration or maintenance of a fixed network terminal by a user is not possible.

It is therefore an object of the invention, including those conducted Landline telecommunication terminals for easy and convenient Configuration and maintenance by a person about the user, to allow, without the configuration of the terminal itself must be undertaken.

These Object is achieved by a method mentioned in that According to the invention for entering the useful data to the telecommunication network allocated from the Landline telecommunication terminal uses different input device is, and the configuration message by means of a part of the transmitted telecommunications network running messaging service on the landline telecommunication terminal becomes.

at a use of the method according to the invention is it for a user no longer not&lt;?page 3?&gt;manoeuvrable, the configuration of a terminal of a wireline telecommunications network over the mostly small keyboard and the small screen of the device to modify. The modification is done in the invention on the Telecommunication network on the basis of certain for the terminal Usage data stored to a service server of the network and the this transmitted to the terminal.

With the invention it is for a user roblemlos possible its landline network terminal to maintain and configure by example with a different from the fixed network terminal Device, as a personal computer, on an appropriate internet site the useful data for its landline network terminal enters. In accordance with these user data now is a configuration message transmitted in the form of a short message to the terminal from which the taken appropriate settings can be.

The transmission the configuration message is carried out in a rapid and reliable manner over a Messaging service of the telecommunication network.

at an advantageous embodiment, the invention, the configuration message in accordance with the created by a user input user data.

there is to enter the user data a telecommunications network associated, miscellaneous to be configured by the or serviceable landline network terminal input device used. Wherein said input device it may be for example a personal computer, via a modem connection or a dedicated line with a wired telecommunications network communicates. Means a corresponding browser program the user can, for example, on a suitably configured Website dial, on which he comfortably the user data destined for its telecommunication terminal, can enter. These are then to a service node transmitted the network and from this in the form of at least one configuration message to the intended terminal Posted.

at the use of a separate input device such as a personal computer is necessary, it is usually that in addition to the user data at least a terminal address, about a number of the connection of the unit or an e-mail address, is transmitted to that of the service node configuration message becomes.

On essential, advantageous point of the invention is that that a modification of the device configuration with respect to the configuration parameters contained in the configuration message after a confirmation input to the terminal takes place. Thus, the final check on the device and its configuration is ultimately with the user of the device, which decides whether the configuration of the device to be changed in the new configuration or not.

Especially it is advantageous if the configuration message in step a) brought into a short message format and the short message thus generated is emitted using a short message service.

there then before sending the short message over an adequately specified data link layer realized a logical connection and the short message in short message format in an adequately specified physical layer over DTMF or FSK off-hook signaling to a Short Message Service Center Posted.

The Using an SMS service allows particularly rapid configuration the fixed network terminal.

The Invention and other advantages is explained below with reference to the drawing. Show this

The <figref idrefs="S22">1</figref> shows a fixed telephone network PSTN, for example, a so-called a / b wireless network (Often not quite accurate also called analog network), to the plurality of terminals invention GEG, GEG 'are connected, For example, an answering machine or a cellular phone system based to the DECT standard. The terminal GEG, GEG 'are on phone interface TSS, TSS 'to the Telephone network PSTN and connected as devices for use realized in the context of the invention; next are more terminals TNB, TNB ', ... shown what directly or through other networks of the PSTN network are starting reachable. also is still a Input Devices PEC, such as a personal computer, shown, via a Modem MOD or a dedicated line, etc. to the telecommunication network PSTN communicates.

Of Further, in the drawing, a service server SRV of a service provider, as the operator of the telecommunications network, represented the is configured to present on the basis of his user data configuration messages create containing configuration parameters for a particular terminal GEG, GEG ', a Connection to the terminal via the establish telecommunications network and the corresponding message to the particular terminal to be transmitted.

Finally, yet another service node of the telecommunications network SSV shown, will be discussed on the further down in the text more accurate.

The <figref idrefs="S22">2</figref> shows a connected to the fixed telephone network PSTN terminal GEG, which adapted for use in connection with the invention. The terminal GEG has a transmitter / receiver unit SEE to which the implementation of the communication functions with the fixed network via the phone interface TSS is used, and a memory SPR and control means STE, eg in the form of a processor device. In addition, the terminal has mostly nor an input / output EAG on which, for example, a. keyboard and may a display, or in addition - at about an answering machine - yet comprises a speaker and a microphone. The input / output is used to operate the equipment as well as the input and modification of device configurations through the Users etc.

In the memory SPR, for example, in a permanent memory PSR the terminal GEG is stored the configuration of the device. In addition, even be it expedient when a read / write memory SSR as a RAM memory, for example for caching incoming configuration messages, as part of the memory device SPR is provided.

Basically, a user now configure his terminal directly on the terminal, under Using the input / output of the device, change or completely new enter. However, many users shy away from these changes di rectly on the device make, since due to the small keyboard and the small displays the devices entering parameters cumbersome, confused and also very prone to error is.

at Use of the method according to the invention with a correspondingly appropriate equipped terminal GEG, GEG contrast 'is the configuration change substantially simplified. According to the invention have the Parameter no longer on the device be entered, but these parameters are the terminal in the form of one or more configuration messages over the Telecommunication network PSTN by a service node SRV, for example, a services server, transmitted.

Of the Services server SRV creates the configuration messages on hand of present him payload destined for a particular terminal GEG, GEG '. To it is initially necessary to the service server, the corresponding to provide useful data. In an advantageous embodiment of the Invention are doing this payload to the service server of the user of the terminal entered. The user used an input device PEC, for example, a personal computer, via which a modem connection or a dedicated line, etc. to the telecommunication network connected is. about a corresponding terminal program or the use of an Internet browser the user can, for example, on a website the einzu service provider changing parameters for his terminal enter. The entry of the parameters designed in this way clearly and therefore has only a low error rate.

In addition to the operating parameters, it is also necessary that the user an address of his terminal, For example, the line of the terminal number assigned or the e-mail address of the terminal indicating thereby the services server SRV correct communication the configuration message, the reference to the input by the user User data was created, possible is.

Around the abuse of the process of the invention to prevent, it is still further &lt;?page 5?&gt;advantageous if each user, who wants to make the invention advantage of, has a password, which he compared to itself can authenticate to the system, so it just him or by him authorized persons is to change the configuration of the terminal.

A another possibility amending configuring the parameters of a terminal is this from the service provider or by a network operator, etc. remote maintenance allow. For this it is in an advantageous embodiment of the Invention for the time being the user need to contact the operator or service provider to put in contact. This happens, for example, by selecting an application made by the provider / operator is available, in accordance with decorated service node SSV, as a service server of the telecommunication network PSTN. After selecting the service node SSV is a network connection to the corresponding terminal GEG, GEG 'produced and whose configuration is read. Then this read Configuration with a predetermined configuration compared, and with a deviation from this, a configuration message prepared and transmitted to the terminal.

at the service server SSV, this may be one own, of the service node or service server SRV of the network PSTN independent nodes act, or the functionality of the two nodes are implemented in a single node or server.

in the occurs case of realization of the functionality in a single server reading the configuration, the creation and the transmission of the configuration message to the terminal from a single server.

If the radio tonalities are divided into approximately two servers, such as the possibility exists, that after selecting the service node SSV by a user of sits down with the corresponding terminal in connection and its Configuration reads. This configuration is then sent to the service node SRV transmitted, in which the comparison with the predetermined configuration, and where appropriate, generation of at least one configuration message and the transmission the same to the terminal takes place.

It but may for example also be provided that from the service node SSV read the configuration of a predetermined configuration compared and submitted the relevant data to the service node SRV be where the configuration message is created and transmitted to the terminal becomes.

A another possibility is that approximately only the selection on the service accounts SSV done, of a service node SRV communicates this the network. select the message, and any other, already described above points take place on the part of the service node SRV.

The Select the service node SSV is now part of the user either by use of the terminal to be configured GEG, GEG 'itself or by Using a suitable terminal to the telecommunications network PEC PSTN.

in the Case of using the terminal to be configured for Select the service node is advantageous that here basically no other entries are necessary because the service node about to The hand from the device via the mitübermittelten network Port number, no additional information for reading or Services node SRV no further in formations to send the Configuration message required.

A but call for remote servicing may also by another terminal PEC of the telecommunications network, such as another to the network connected phone or, for example, a personal computer done. In this way the maintenance of a device may also be occur when the user logs on to the place immediately before Device is located.

at Using a personal computer or similar device is in front particularly advantageous for the user in a simple and convenient Way may yet he desires Specifications concerning the configuration process or the configuration itself can enter.

Becomes for selecting the service server SSV not serviceable terminal itself but an input device used, it is necessary that at least part of the user an address of the terminal GEG, GEG entered ' is, under which the Service or service node, the terminal for the elite the operating parameters and the transmission of can address the configuration message (s) and reach.

Concerning reading the current configuration of the serviceable terminal sets After selecting the service node SSV this or the services node SRV with the corresponding terminal in conjunction. By means of corresponding commands on the part of the node SRV, SSV of are telecommunications network PSTN, either directly the operating parameters the terminal GEG, GEG 'read, or the terminal is caused to erstel an operating parameter message&lt;?page 6?&gt;len and to transmit them to the respective nodes.

there after receiving the appropriate command from the transmitter / receiver unit SEE creates the operating parameter message from the controller STE, forwarded to the transmitting and receiving unit SEE, of which they a Network connection, which for this purpose by the transmitter / receiver unit is prepared to the appropriate server - which is usually that, from which the command for generating the operating parameters message comes - received becomes.

The News as configuration messages or operating parameters messages are from one server SRV or a terminal GEG, GEG 'to at least one the terminal or the Sending server assigned address. In practice, it is often necessary and also to realize easily that the message is also sent to multiple addresses. is at the address it is advantageously a number, as the number a terminal GEG, GEG 'user, or to a device or assigned to the server e-mail address; the respective message is then by one of the fixed network supported PSTN Messaging service received, wherein the message in one of the messaging service appropriate form of the server SRV on the charges requested connection the device GEG, GEG '(or vice versa) is transmitted.

Especially it is advantageous if the messages by means of the Setting the fixed line network running messaging service for transmitting messages sent to the address in text format , whereby in the purposes of the invention, in particular an e-mail service ( "electronic mail") or an SMS service ( "SMS", "Short Message Service ") suitable.

Of the SMS service, the particularly rapid user notification allows is the GSM network known and provides a point-to-point transmission there of short messages. An example of an implementation of the SMS service in a line-bound telecommunications network is down in the "transmission a message as a short message "closer described. In the use of such SMS service the transmission is of up to 160 characters long message content in a short message possible.

transmission a message as a text message The SMS service is used for point-to-point transmission short messages ( 'Short Messages') and is under the GSM protocol architecture realized on the signaling level. there He includes transportation packet-oriented useful data from and to mobile stations. The short message are always on a short message service center (SM SC = 'Short Message Service Centre') in the store-and-forward operation transported. The service center accepts long the maximum of 160 characters Short messages from a mobile station as the telecommunication terminal counter and forwards them to a second telecommunication terminal - a further Mobile station or else a fax or the like -.. On.

to Realization of the SMS service of the GSM standard defines a special Protocol architecture. This is defined in the ETSI specifications and is adequately described in the literature (see. about J. Eberspächer, H. J. birds: 'GSM Global System for mobile communication ', Stuttgart, 1997), so that a detailed description is dispensed with here and on the attached Standards / documents can be made.

The Realization as used herein the short message service in the fixed network closes the fundamental idea a, regardless of the profound System differences between mobile networks on the one hand and the known wireline networks on the other hand the proven SMS protocol architecture the GSM standard (or a similar architecture to fixed lines depict UMTS standards) to a certain extent and expand.

With the specifications described below, the transfer protocol and the physical and administra tive requirements for transmission short messages in the short message (SMS) format between the terminal and the Short message service center defined. The transmission protocol is here preferably in close alignment with the defined in the GSM standard protocol set. Herewith the aim is the transmission of short messages as for landline new service with low cost and high compatibility with existing offer systems. There is a uniform SMS format in the GSM network and used in the fixed network, thereby also the smooth transmission constructed of short messages between a according to the GSM standard, ensured and operated mobile network and the invention equipped landline becomes. In addition, the chosen with this embodiment of the invention provides Way the considerable practical advantage that the specification the SMS service largely recognized in the meantime, and tried and tested GSM specifications resorted can be.

In the physical layer, the data transmission between terminal and Service Centric&lt;?page 7?&gt;rum means of DTMF signaling and / or via a by ETS 300659-1 and ETS 300659-2 specified FSK ( 'Frequency Shift Keying' - Frequenzumtastkodierung) Off-hook signaling. This said transmission method can in any combinations are used. In particular, a fixed-terminal signaling make by DTMF and the service center, the FSK modulation use, of course, adjusted each receiving unit for the process used have to be.

Above the physical layer is a Data Link layer specifies the logical connection setup and the fitting to the default GSM SMS guaranteed. The latter standard is in particular in the ETSI document GSM04.07- (ETS 300 556), defined GSM04.11 and GSM03.40. In this compatibility , the data link layer be defined to suit the specific requirements dates.

According to a advantageous form this solution are the newly defined physical layer and data link layer with the existing Layers ( 'Layers') of the GSM-SMS protocol set combined. This is the Short Message Transfer layer ( 'Short Message Transfer Layer ', SM-TL) in accordance with ETSI document GSM 03:40, the short message relay layer ( 'Short Message Relay Layer ', SM-RL) by GSM 03:40 and 04:11, and the connection management layer ( 'Connection Management Layer ', CM) after GSM 04:11.

In the last-mentioned layer CM specifically defines an additional Message for signaling the connection state ( 'CP-Connect') defines the Format to GSM 04.07, section 11, is determined. A special Down there also in terms of the format of a message in the data link layer DL. This will be discussed in more detail below.

in the Hereinafter, with reference to the <figref idrefs="S23">3</figref> to <figref idrefs="S26">7</figref> the transmission short messages using the example of a short message exchange between a terminal CD (representative of one of the devices GEG, GEG ', SRV, SSV the <figref idrefs="S22">1</figref>) and the device attached to the fixed network short message service center SM SC shown. relate to the interaction of these components the following statements In order to explain the invention.

<figref idrefs="S23">3</figref> shows the associated SI-layers model physical, above (not shown here) Layer. The layer structure includes a first - in more detail below specified - Data link layer DL ( 'Data Link Layer') and continue the per se known from the GSM-SMS standard layers Connection Manager CM ( 'Connection Manager '), short message relay layer SM-RL ( 'SM Relay Layer') and short message transfer layer SM-TL ( 'SM Transfer Layer ') and - on the side the terminal - the Application layer ( 'Application').

The Protocol descriptions of the layers SM-TL, SM-RL and CM are the ETSI documents GSM 03:40 and GSM refer 4:11.

The Prerequisite for transferring Short news the fixed network PSTN is a circuit switching between the participating units (terminal CD and short message service center SM SC). It is then immaterial whether the units via ISDN or an analogue interface are connected.

In <figref idrefs="S24">4</figref> and <figref idrefs="S25">5</figref> is schematically the structure of a compound, starting from a telecommunications terminal (<figref idrefs="S24">4</figref>) Or starting from the short message service center (<figref idrefs="S25">5</figref>) Shown. These graphs are for the skilled person itself explanatory and require therefore no further explanation here.

in the The case of an ISDN network are the messages ( 'Messages') of a functional nature, and are transmitted in the ISDN D channel. In an analog network is Ringing pulses and busy signals. After construction the compound are all Information transmitted between the units by FSK signaling in the voice band, specifically in accordance with the ETSI specifications ETS 300659-1 and ETS 300659-2.

In <figref idrefs="S26">6</figref> is the construction of an additional message 'CP-Connect' shown that the Notifying the calling unit from the called entity over the Establishment of the connection is used. This notification is required, to the processes in the CM layer to set in motion. The Nachrichtenartkodierung is: 0 × 40 = 0100 0000B, and the format follows GSM 04.7, Chapter 11th

The Layer DL enables the connection manager (layer CM) to send and receive messages with the partner unit, it represents the bit error prepared and implemented for Message in the layer CM, a warning signal ( 'Mark signal').

In <figref idrefs="S26">7</figref> is illustrated the format of a message in the data link layer. The "mark signal" comprises a Block of 80 ± 25 bits. The "Message field Type "includes a contains octet and a binary coded identification number for the message. The coding for a DL SMS &lt;?page 8?&gt;INFO Message Type is: 0 × 11 = 0001 0001B. The coding for one DL SMS ERROR Message Type is: 0 × 12 = 0001 0010B.

The Field "Message Length" includes one octet and contains the binary coded number of octets of the message (excluding the octet the message type, the message length and the checksum). A total of is a message length allows up to 255 octets. The field "checksum" comprises one octet and contains the two Complements of the sum of all bytes in the message, starting the "message type" octet to the end, modulo 256th

in the Case of a checksum error sends the data link layer of the receiving unit is a Message type "DL_SMS_ERROR" to the (original) sending entity. In this message, the data field is empty and the message length (Message Length) is set to zero. The data link layer the sending unit must thereupon the last message sent to repeat.

to physical layer is also to be noted that in case of FSK signaling used a half-duplex 1200 baud modulation can be. In case of DTMF signaling, each octet a message in the data link layer in the higher (upper) and lower (bottom) divided nibble. Each nibble is encoded with a DTMF bit. First, the upper nibble is sent and then the lower. in the Case of DTMF signaling is the warning signal of the DL message omitted.

Regarding the signaling method are various possibilities of combination; Normally, a selection in the telecommunication terminal CD firmly installed, then the user or service provider not changing more is.
