Description

The The present invention relates first to a method for Establishing a Remote Communication Link Between One Remote client and a remote server according to the The preamble of claim 1 and a method of communication between a remote client and a remote server according to the The preamble of claim 8. Furthermore, the invention relates a mobile terminal, a client station and a communication network.

in the State of the art, it has long been known communication links between remote devices, called remote communication links, manufacture. In a network, it can be with such devices for example, to act as so-called clients (remote clients), which communicate with a remote server (remote server).

To is usually implemented in the client software over which connects the client to the remote server to the client becomes. This can be done for example via the Internet. The connection is made as part of a registration procedure in which especially passwords, identifiers and the like exchanged Need to become. This is complicated and thus disadvantageous because this is usually a manual procedure.

The Development in the field of communication setup between removed lying devices has advanced greatly in recent years.

For example, in the DE 601 15 725 T2 A method and an arrangement for configuring communication sessions in a communication network are described. This establishes a communication link between a remote client and a remote server located in a home network remote from the remote client. For this purpose, the remote client, such as a mobile computer or the like, linked to a mobile device, such as a mobile phone. Subsequently, a connection is established from the remote client to the remote server via the mobile terminal. According to this known solution it is provided that the mobile terminal is located in a mobile network, while the remote server is to be located in a private IP network. The remote client connects to the remote server using the familiar solution over the cellular network, the public Internet, and the private IP network. The connection according to this known solution is established according to the standard PDP context procedure (PDP = Packet Data Protocol).

there is after the known solution the mobile terminal, a mobile phone, the so-called "mobile termination" (MT) according to the 3GPP standard (3rd Generation Partnership Project) assigned. This is a component of a mobile station that especially supports functions that are specific to the management of the radio interface are.

the in the known solution disclosed remote client, a mobile computer, is the so-called "terminal equipment" (TE) assigned to the 3GPP standard. This is one or more component (s) providing / providing functionalities, those for the operation of the access logs on pages the user is required. The terminal equipment represents a functional Group on the user side of a user network interface.

Across from In a network, the MT component and the TE component functionally represent the Mobile station, wherein in the known solution, the two Components are divided into different devices.

Yet can also with the known solution the beginning described disadvantages are not satisfactorily eliminated become. In addition, the server is the client always clearly identifiable.

outgoing Of the cited prior art, the present invention the task of creating a solution by means of which can be circumvented the disadvantages described above. In particular, a solution should be provided by means of It easily connects a remote client and a remotely located remote server, without doing the identity of the remote client server side must be known.

This object is achieved according to the invention by the method for producing a remote communication link having the features according to independent claim 1, the method for communicating with the features according to independent claim 8, the mobile terminal having the features according to independent claim 9, the client Station with the features according to independent claim 13 and the communication network with the features according to independent claim 14. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with one of the aspects of the invention, of course always in connection with the respective other aspects of the invention, and vice versa, so that with respect to the disclosure of individual features in the individual aspects of the invention reciprocally always reference to the other aspects of the invention and incorporated by reference.

Of the The present invention is based on the idea that now for establishing a communication connection between at least one remote client and a remotely located remote server a specially trained mobile device used which acts as a so-called proxy server, respectively is trained.

According to the The first aspect of the invention is a method of manufacturing a Remote communication connection between at least one remote client and a remote server in a first communication network, in particular a computer network. The method is according to the invention by in that the production of the remote communication connection by means of a mobile terminal in a second communication network, in particular a mobile network, is that the mobile terminal as a proxy server between the at least one remote client and the remote server and that is a communication connection setup between the mobile device and the remote server as well regardless of a communication connection setup between the mobile terminal and the at least one remote client he follows.

The inventive method is used for the production a remote communication link between at least one Remote client and a remote server.

A Remote connection is generally a connection between removed lying devices, such as computers or the like. For example, such a connection may be distinguished by that it does not have a Local Area Network (LAN) connection, that is, does not contain a physical connection. Rather, it stands out A remote connection is usually characterized by being over other interfaces, such as the Internet or the like, comes about. A remote communication connection is one Remote connection, for the purpose of communication between removed lying devices is built.

One Client is generally a component that is specific to a server Request service and wait for an answer. A remote client is therefore a client that is removed with regard to the server lies. For example, a client is a software or hardware that can use certain services from a server. Of course For example, the invention is not limited to particular types of clients. In the further course some are not exclusive Examples of clients are described. in principle However, it is advantageous for a client to have a computer unit has, by means of which a communication connection is established can.

Under In general, a server is a component that orders receives from clients, processes these jobs and returns a response to the client. A remote server is therefore a server that is removed with respect to the client (s) lies.

at A network-type client-server architecture becomes a task split on the connected computers. Mostly this is the server the service provider and the client the customer.

Of the Remote server and the at least one remote client are located in a first communication network. That means the components run under the protocols of the first communication network and are registered in this particular. Here is the invention Of course not limited to certain types of first communication networks. For example, a suitable first communication network may be to act on a computer network, such as the Internet, or the like.

The Method is according to the invention first characterized in that the manufacture of the remote communication link by means of a mobile terminal in a second communication network he follows. Of course, the invention is not limited to certain limited second communication networks or certain mobile devices. The second communication network is in particular one that differs from the first communication network. For example, but not exclusively, it may be in the second communication network around a telecommunications network, for example, a mobile network, act. This second communication network are assigned to mobile devices, which means that the mobile Terminals under the protocols of the second communication network run and are registered in this particular. It is the Invention is not limited to certain types of mobile devices. For example, but not exclusively, it may be in this case to telephone devices, in particular to mobile phones act.

According to the invention, it is further provided that the mobile terminal acts as a proxy server between the at least one remote client and the remote server.

One Proxy (server) is generally a kind of "proxy device", the origin of a communication link, such as a Connection on the Internet, hides. To build a terminal a user, such as a (remote) client assigned to the user, first connect to the proxy (server). This builds then, in turn, and thus representative, the user desired connection to a destination server, for example a remote server, on. Is a communication connection between a client and a destination server without using one in between switched proxy (server), the transmitted Client during communication setup also identification features, for Example an individual IP address. This is usually on saved to the destination server. Now if a proxy (server) is used, so the request is sent from the client to the proxy (server) and from there forwarded to the destination server. This gets the Destination server but not the IP address of the client, but only transmits the IP address of the proxy (server), causing the Client identity for the destination server remains hidden.

By this particular embodiment of the mobile terminal is it is possible that on the one hand a communication connection setup between the mobile device and the remote server and, secondly, regardless of that, a communication connection setup between the mobile terminal and the at least one Remote client is done.

Thereby can be advantageously realized that the remote server existence the remote client no longer knows or needs to know about a communication connection to be able to produce. The remote server connects to the acting as a proxy server mobile terminal ago, which, as explained in more detail later will bring other benefits as well. additionally the mobile terminal also connects to the Remote client forth, allowing a communication link between the remote client and the remote server via the mobile device comes about.

Of the Advantage of the method according to the invention by way of example, without the invention however, would be limited to this example. For example could the client be a computer, a Screen or a computer provided with a screen. In particular, the client should have a computer as described above exhibit. About the acting as a proxy server mobile Terminal can connect to this client and simultaneously also connect to a remote server. After establishing the communication connection, a user can working on the client while looking at data and services of the remote server access. Advantageously, the communication takes place after successful Production of the communication connection via the mobile Terminal. At the same time, however, the client faces the remote server does not appear. Such a constellation enables completely new areas of application, as in the following History will be explained in more detail. It will be like this For example, with the present invention, to provide so-called client stations that merely out a computer screen, a computer keyboard and a computer mouse can exist.

One User who has a suitably trained mobile Terminal device can be via its terminal connect to the remote server using the mobile Terminal simultaneously with at least one of the clients the client station is connected. The user can now use the client station use it as if he were working on a full-fledged computer sit, with the server functions of such a computer over The remote server will be provided and the exchange of information about the mobile terminal takes place. How this is done in detail will, in the further course of the description in larger Detail explained.

Especially Also, the authentication and identification procedure can be significant be improved. As stated in the introduction to the description is based on previous authentication procedures for Remote communication connections so far on the - mostly manual - enter username and passwords. Now, identification means the mobile terminal, such as on a smart card, about a SIM card, stored for authentication purposes to be used at the remote server, which in particular automatically can be done so that manual entries are unnecessary become. Advantageous embodiments thereof are in further course described in detail.

The present invention thus describes a mechanism in which a mobile terminal, such as a mobile phone, serves as a proxy server for a remote communication connection, such as a remote desktop connection. For example, a computing device may be connected to normal computer peripherals, such as a computer screen, a computer keyboard, a computer mouse, or the like, thereby creating a remote client. The mobile terminal, such as a mobile phone, which proxy ser ver is at least temporarily connected to the remote client. This can be done in a variety of ways, such as wirelessly using a short-range communication device. At the same time, the mobile terminal is also connected to the second communication network, such as a mobile network. The second communication network can, as will be explained below, assign the mobile terminal an addressing, via which a connection to the remote client can be generated. Software in the remote client can now use the mobile terminal as a proxy server with respect to the remote server. This proxy server is able to use the mobile device located in the identification data, which may be stored for example on a smart card, to authenticate the user to the remote server.

Advantageous can be configured as a proxy server mobile device addressing by the second communication network, in particular an IP address, get assigned, with the connection from as a proxy server trained mobile device to the remote server over the assigned addressing takes place.

One Router is generally a device for coupling networks, wherein the networks have the same communication structure can. In particular, a router may be a device that makes a coupling between two or more similar networks. For example, a router may be a device between two or more computer networks, about two or more IP networks (networks based on the Internet Protocol).

Preferably can be configured as a proxy server mobile device when establishing a communication connection to the remote server identification data transmitted to the remote server, with the identification data stored in particular in the mobile terminal, preferably on a smart card, such as a SIM card or the like. To this Way, the mobile device - and thus the associated users - in a simple way when Remote server to be authenticated.

Around to avoid the disadvantage of a manual authentication procedure, Now, the proxy server is used, which is preferably is a mobile phone with SIM card. The advantage is now in that when connecting between the remote client and the remote server the authentication data of the proxy server, that is, the mobile terminal being pulled, for example, stored on the SIM card. This authentication data will be sent to the remote server. This is preferably done by connecting the remote client to the remote server via the mobile terminal is built. Alternatively, too conceivable that a direct connection between remote client and Remote server is set up that the authentication data from the Transfer the proxy server to the remote client and from there then transferred to the remote server.

Preferably can be provided that the remote server to a storage device within the second communication network, in which Identification data of registered in the second communication network Mobile devices are stored that the remote server that of the mobile terminal designed as a proxy server obtained identification data with the in the memory device stored identification data compares and that the remote server if there is a match, the communication connection to the trained as a proxy server mobile device manufactures. In this way, the remote server can access so-called "subscriber data". access the acting as a proxy server mobile terminal. If the remote server has the authentication or identification information receives the mobile terminal, he compares these with the "subscriber data" and adjusts the connection.

Advantageously, the communication between the at least one remote client and the mobile terminal designed as a proxy server take place via a device for short-range communication.

Of course, the invention is not limited to certain distances limited. These arise rather from the field of application, on where a short-range communication should take place.

Advantageous may be the device for short-range communication as so-called NFC device (Nearfield Communication), as an RFID device (Radio Frequency Identification), or the like.

RFID is a method by which data is transmitted without contact, can be read and stored. The data will be stored on an RFID chip. The reading out or writing the memory is via radio waves. The distance, over which such an RFID chip can be read depends of its execution, the frequency band used, the transmission strength, from environmental influences and the like.

Preferably has the at least one short-range communication device, For example, the RFID element, a transponder for sending and / or Receiving data. A transponder generally consists of one Processor unit and an antenna. Optionally, this can also over have their own energy source. In this case speaks one from an active transponder. A transponder without its own energy source is referred to as a passive transponder.

active Transponders are usually in a rest position, in which they send no signals. Only when you have a specific one Activation signal received activates their transmitter. active Transponders have one compared to passive transponders larger transmission range.

passive Transponders do not have their own energy source. They get their energy to transmit information from the received radio waves. Passive transponders feature compared to the active transponders over a lower one Range.
