Abstract

A communication system is proposed in which a call arriving at a communication terminal (4; 5) is signaled to all communication terminals (4; 5) present in the system regardless of what terminal had received the call, including those terminals that had not arrived at the area of the communication system until a later time. Voice call transfers are also possible between said communication terminals (4; 5). Also proposed are a communication terminal (4; 5) and a transfer point (2) for use in the communication system. This object is achieved by components (4; 5; 6; 7) comprising means for such work, that when said communication terminal (4) arrives in an area belonging to said transfer point (2) the transfer point (2) carries out an automatic forwarding of the profile of the communication terminal (4) arriving in the area to the administering component (6), that thereupon a reporting of the communication terminal (4) arriving in said area is done, with reporting data of said terminal, to a responsible server in the public computer network by the transfer point (2), that reporting data associated with the administering component (6) is then transmitted to the communication terminal (4) arriving in the area, and that the communication terminal (4) arriving in the area then reports to the administering component (6) with the reporting data thereof. A communication terminal and transfer point that can be used in such a communication system comprises the correspondingly tailored means for this purpose. DRAWING: FIG. 2:

Communication system and communication terminal and transfer point for use in the communication system

The invention relates to a communication system according to the preamble of claim 1. The invention further relates to a communication terminal and a transfer point respectively for use in the communication system.

The following terms are used in particular with the following meanings known in the technical art:

Dual Mode A dual-mode device is a mobile station that supports completely different transmission methods, standards and networks. Such a device could e.g. be designed for GSM networks and WLAN or for GSM and CAT iq. The user is therefore not set to a special standard.

Global System for Mobile Communications (GSM) standard for full digital mobile networks used primarily for telephony, but also for circuit-switched and packet-switched data transmission and short messages.

UMTS: (Universal Mobile Telecommunications System) Mobile standard in analogy to GSM, but more powerful.

WLAN: (Wireless Local Area Network) Wireless, local wireless network.

DSL: (Digital Subscriber Line) Digital subscriber line for high-speed wired data transmission.

Router: device from the field of computer networks or telecommunications or the Internet, which couples or disconnects multiple computer networks. Hotspot (WLAN): Public wireless Internet access point. SIP: (Session Initiation Protocol) Network protocol for establishing, controlling and reducing a communication session between two and more participants.

SIP profiles: Compilation of all access and configuration data necessary for logging in a SIP client on a SIP server, e.g. Service provider, user name or password.

Client: A computer program that connects to and exchanges messages with a server based on the client-server model. VoIP: (Voice over IP) Internet protocol telephony, being telephoned over computer networks, which are set up according to Internet standards. There will be information typical for telephony, that is speech and control information e.g. for establishing a connection, via a network which can also be used for data transmissions. Among the participants in the discussion, both computers, communication terminals specialized for IP telephony, as well as classic telephones connected via special adapters can connect to the telephone network.

Gateway: Protocol translator that allows networks based on completely different protocols to communicate with each other. Home area: home office area. Customer group description in the field of information technology for professional network-enabled products that are designed for one or a few users.

SoHo area; Small office area. Customer group description in the field of information technology for professional network-enabled products that are designed for a few users. Proxy: Has the function of a substitute who acts as a mediator who receives requests on the one hand, and then connects to the other via his own address. He takes on behalf of the requesting client communication with the destination or simply passes the requests under his name to the destination without the communication itself. Alternatively, it may also appear as a supposed target system, with the address translation then being made in the opposite direction.

PBX: (Private Branch Exchange) Internet-based variant of a telephone system.

Server: Program as part of the client server concept. It communicates with another program, the client (customer), to give him access to special services. IMS: (IP multimedia subsystem). The IMS is a collection of specifications of the latest technology. The goal of IMS is standardized access to services from different networks. IMS supports all IP-based communication. But it also supports existing networks such as GMS or the conventional analog and the digital (ISDN) telephone network. Typical services are VoIP telephony or presence information. The basic protocol of IMS is SIP, which establishes connections between the participants via a dedicated IP network.

ISIM: (IP Multimedia Services Identity Module). Application that contains parameters for identifying and authenticating a user to IMS. DECT: (Digital Enhanced Cordless Telecommunications). Standard for cordless phones as well as for wireless data transmission in general.

CAT-iq: (Cordless Advanced Technology - internet and quality) CAT-iq radio technology is based on DECT and combines Internet and telephony.

Dual mode devices for GSM / UMTS and WLAN are already available today. These devices can be connected to Wi-Fi via Wi-Fi.

Router or a public Wi-Fi hotspot. If the devices are also equipped with a SIP client and a corresponding SIP profile (for further considerations please briefly refer to "Private"), VoIP calls can be made via the WLAN connection.

On the other hand, VoIP gateways for the home and SoHo area are now equipped in part with a SIP proxy and a VoIP PBX function. The SIP proxy manages one or more SIP profiles (for the further considerations below, briefly referred to as "family") and connects them to the individual communication terminals that are logged on to the SIP proxy.

The disadvantage is that when the above-mentioned dual mode device comes into the radio range of a described VoIP gateway, there is no default connection between the SIP proxy and the VoIP PBX function in the gateway and the SIP profiles in dual mode Device gives.

The situation is such that while an incoming call on the phone number of the "Family" SIP profile is signaled on all communication terminals registered with the SIP proxy, the call is not signaled on the dual mode device. Conversely, an incoming call on the telephone number of the "private" SIP profile is indeed signaled at the dual-mode device, but the call is not sent to the other communication terminals present in the home network, that is to say at the communication terminals which are connected to the SIP. Proxy logged in signals.

Regardless of the aforementioned problems, there is the additional problem that a handover between the communication terminals in the home network, that is, the communicated to the SIP proxy communication terminals, and the dual mode device is not possible.

It is therefore an object of the present invention, starting from a communication system of the type mentioned above, to technically improve this in such a way that it integrates communication terminals that newly enter the communication system, regardless of which communication terminal in the communication system has a call arrives, this call is signaled to all existing in the system communication terminals, or, if not yet additional filtering measures to be activated, at least this possibility exists.

In addition, it is an object of the present invention to facilitate call transfers between all existing in the system communication terminals.

It is another object of the present invention to provide a communication terminal, which can be used as a communication terminal in the communication system according to the invention.

Finally, it is an object of the present invention to provide a transfer point which can be used as a transfer point in the communication system according to the invention. The above object is achieved on the one hand according to the invention by a communication system having the features in the characterizing part of claim 1.

The above object is further achieved according to the invention by a communication terminal, which corresponds to claim 9.

The above object is finally achieved according to the invention by a transfer point, which corresponds to claim 10.

The communication system according to the invention has the advantage that regardless of which communication terminal in the present communication system a call arrives, this call is signaled to all communication terminals present in the system, or, if not additional filter measures should be activated, at least this possibility exists.

Furthermore, it is advantageous that call transfers between all communication terminals present in the system are possible.

An inventive communication terminal or a transfer point according to the invention have the advantage that with them a communication system can be constructed, which has the aforementioned desired advantages.

Advantageous embodiments of the invention are the subject of dependent claims.

Thereafter, it does not matter what kind a relevant communication terminal is. It may, for example, be a GSM, UMTS, DECT and so on communication terminal.

It is furthermore advantageous that the communication system according to the invention can be combined with already known techniques, such as, for example, VoIP and the processing of SIP profiles, IMS with the processing of ISIM or the PBX function can be realized.

The basis of the measures according to the invention is that an affected transfer point has means for automatically transferring the profile belonging to the communication section in the said area to a management component connected to the transfer point when the affected communication terminal arrives in a region belonging to the transfer point.

The arrival of an affected communication terminal in the said area of the transfer point can be done by a direct, wired coupling or in the presence of a radio-based transfer point by getting into a belonging to the transfer point radio range.

Another basis is that the transfer point has means for subsequent registration of the received in said area communication terminal with its credentials to a competent server for data and voice on the public computer network in such a way that the application for the addressed management component is transparent.

It is also based on the fact that the transfer point has means for a subsequent transfer of registration data belonging to the administration component to the communication terminal that has arrived in the said area.

Finally, the basis is that the communication terminal which has arrived in the said area has means for a subsequent subsequent log-on to the management component with its log-on data.

An embodiment of the invention will be explained in more detail with reference to a drawing. Show: Figure 1 shows a communication system with a transfer point and a respective communication terminal respectively according to the invention in a so-called "on the way" situation, and Figure 2 is a communication system according to the figure 1 in a so-called "home" situation.

FIG. 1 shows on the one hand a home or SOHO area 1 for a home or SOHO telephone system 2 and on the other hand an on-the-go area 3 for a radio-based and as such according to the present exemplary embodiment the UMTS / WiFi standard belonging dual mode communication terminal 4 shown.

The telephone system 2 in the home or SoHo area 1 is, for example, a VoIP gateway with a VoIP telephone system with at least one single VoIP communication terminal 5. As far as VoIP communication terminals 5 are present, they are on the VoIP telephone system. 2 Registered.

In addition, the VoIP telephone system 2 is assigned a SIP profile, hereinafter referred to as "family." The VoIP telephone system 2 logs on with the SIP profile "Family" to a SIP server in a public computer network (Internet).

An inherently existing in the VoIP telephone system 2 SIP proxy in turn manages the respective SIP profiles of the VoIP telephone system 2 registered VoIP communication terminals 5 (hereinafter referred to as "Home Gateway").

At the same time, the SIP proxy establishes the connection between a respective registered VoIP communication terminal and the SIP server in the public computer network. In this function, the SIP proxy represents a corresponding administration component 6.

The radio-based dual-mode communication terminal 4 located in the on-road area is, for example, wise, a UMTS / WiFI-capable communication terminal. According to the present exemplary embodiment, the dual-mode communication terminal 4 is suitable for being connected via WLAN to a DSL router or a public WLAN hotspot. Furthermore, the dual mode communication terminal 4 is equipped with a SIP client and a corresponding SIP profile, so that a VoIP call can be made with the dual mode communication terminal 4 via a WLAN connection.

The SIP profile of the dual-mode communication terminal 4 is hereinafter referred to as "private".

As can be seen from FIG. 1, the SIP proxy of the VoIP telephone system 2 only manages its own SIP profile "Family" in the time shown.

FIG. 2 shows a point in time in which the dual mode communication terminal 4 has reached the radio range of the VoIP gateway and thus into the area of the VoIP telephone analyst 2.

The SIP profile "Private" of the dual mode communication terminal 4 is automatically forwarded to the SIP proxy of the VoIP telephone system 2 as soon as the dual mode communication terminal 4 is in the radio range of the VoIP gateway the VoIP telephone system 2 with the credentials of the "private" profile at a competent SIP server for data and voice in the public computer network. The SIP proxy and the VoIP telephone system 2 now manage the SIP profiles "Family" and "Private".

The dual-mode communication terminal 4 now receives the log-on data "Home Gateway" for the SIP proxy of the VoIP telephone systems 2. With these log-on data, the dual-mode communication terminal 4 now logs on to the SIP proxy of the VoIP telephone system 2 Thus, the dual mode communication terminal 4 is otherwise logged on to the SIP proxy VoIP communication terminals 5 compared to an equivalent communication terminal, which can be operated on the SIP proxy of the VoIP telephone system 2.

If the dual mode communication terminal 4 leaves the radio range of the VoIP gateway, everything is undone.

The exchange of profiles and credentials can also be used for IMS communication terminals with corresponding ISIM.

With the measures described above, as soon as a user is at home, incoming or outgoing calls on the telephone number of the "private" SIP profile can be routed to all VoIP terminals in the house, eg with a CAT-iq communication terminal In addition, the user can also lead or forward incoming or outgoing calls with the number of the "Family" SIP profile to the dual-mode communication terminal. The user does not have to do this manually because the data is exchanged automatically.
