If the phone is 120 in his charger 123 is the base 101 with the phone 120 by means of the radio combination telephone interface module 125 connected. A radio combination phone 102 can in the case with a participant in the GSM network 140 via internal communication between the radio combo telephone interface module 125 and the considered combination phone 102 communicate. The connection between the base 101 and the phone 120 is intended to convey data, especially voice data and command data.

It is worth noting here that if one of the Kombitelefone 102 in communication with an external subscriber in the local network, in the GSM network 140 via internal communication with the combo telephone interface module 125 is another of the combo phones 102 simultaneously with another external subscriber in the local network, in the wire telephone network 110 can communicate.

After the structural description of the local radio telephone network is now the description of its operation during communication of one of the Kombitelefone 102 with an external subscriber in the local network, in the GSM network 140 ,

To the GSM phone 120 recharge it puts his user in the charger, thus on the one hand the charging pads 121 . 126 connects together and on the other hand, the male connection unit 122 and the female outlet 127 connects with each other.

In the case of the cordless phone 120 incoming call, this sends a message of an incoming call in the direction of the DECT combo phone module 125 through the connection unit 122 therethrough. The DECT combo phone module 125 sends in the case in the direction of the base 101 , by radio an internal call order of the Kombitelefone 2 , After receiving the command leave the base 101 the combination phones 102 ring. If one of them decouples, it will move towards the base 101 sent a telephone DECT disconnect command. Upon receipt of this command the base is built 101 an internal communication between the combi phone 102 that has uncoupled, and the DECT combo phone module 125 , generates a telephone uncoupling command and sends it in the direction of the DECT combo telephone module 125 by being incorporated into a specific field of the DECT protocol, in this case in the IWU field of an INFO frame of the DECT protocol. The DECT combo phone module 125 receives this INFO frame, extracts from it the telephonic decoupling order, in other words it removes it, then transmits it again in the direction of the telephone 120 through the socket 127 therethrough. Upon receipt of this data, the phone will disconnect 120 so that a telephone communication between the considered combination phone 102 and the calling subscriber in the GSM network 140 via an internal communication in the local network between the considered combi phone 102 and the DECT combo phone module 125 is built.

To call a subscriber using one of the combo phones 102 in the GSM network 140 call, the user selects the telephone number of the subscriber using the keyboard of the combo phone 102 and prints on the GSM call button. The combination phone 102 sends in the direction of the base 101 an internal call command of the DECT combo telephone module 125 and the telephone number of the subscriber. Upon receipt of this data, the base generates 101 An AT telephone call command and sends it towards the DECT combo phone module 125 with the telephone number of the subscriber by incorporating this data in the IWU field of an INFO frame of the DECT protocol. The DECT combo phone module 125 receives this frame by extracting from it the AT telephone command and the telephone number of the subscriber, in other words taking this data and then back towards the telephone 120 transmits. The latter calls in this case the subscriber to be in the GSM network 140 a telephone communication between the considered combination phone 102 and build the participant.

During a communication between one of the Kombitelefone 102 and an external subscriber in the local network, in the GSM network 140 , communicate the considered Combo phone 102 and the DECT combo phone module 125 with each other in internal communication through the base 101 , The data, especially the voice data, between the combi phone 102 and the external participant will be transferred to the base 1 , the combi phone module 125 and the phone 120 transfer.

During a communication between a first combo phone 102 and a first external subscriber in the GSM network 140 can a second combo phone 102 Simultaneously send or receive a telephone call and in the wire telephone network 110 with a second external subscriber in the local network by means of the base 101 communicate. The base 101 Manages in this case, at the same time the internal communication between the first Combi phone 102 and the combo phone module 125 what the external communication of the first combo phone 102 with the first external participant in the GSM network 140 as well as the external communication of the second Kombitonefons 102 with the second external subscriber in the wire telephone network 110 allowed.

One could also omit the connection and data transmission unit of the battery charger of the cordless telephone and transmit the voice data and command data through the charging pads.

The radio combination telephones could integrate a communication interface unit arranged to generate commands, for example AT commands, to control the cordless telephone from commands detected by means of its telephone keypad.

Furthermore, one could integrate a communication interface unit in the mobile telephone.

In an embodiment variant, the local area network also includes the elements described below.

The charger includes a unit for detecting the presence of the cordless telephone and a unit for detecting identification data of the cordless telephone, in the present case an identification number. The detection unit allows to detect the presence of the cordless telephone in the charger, here by detecting a charging current. The detection unit is designed to detect the identification number of the telephone when the latter is in its charger and to transmit it again towards the base.

The DECT radio base comprises an identification unit and a telephone call control unit. The identification unit is intended to check the validity of the identification number of the cordless telephone provided by the detection unit of the charger by comparison with a pre-registered valid identification number. The telephone call routing unit is intended to control the base under the command of the identification unit to call a telephone call routing server and address to it a routing request for all incoming calls to be transmitted through the wireless network dedicated to the local area network.

It should be noted here that the local area network comprising the base and its radio combination telephones and the cordless telephone each have a telephone number in the RTC network and a telephone number in the GSM network. The routing server, which is connected to the two networks RTC and GSM, is intended to direct telephone calls in one or other of these networks towards one or the other of the telephone numbers.

When a user inserts the cordless phone into the charger, the detection unit searches for the presence of the phone. The detection unit in this case detects the identification number of the telephone stored in the latter and transmits it again towards the base. In the base, after receiving the identification number, the identification unit checks whether the received identification number is valid. If so, the base under the command of the routing unit calls the routing server in the RTC network and addresses to it a routing request to, in other words, transmit the incoming calls intended for the local area network in the GSM network to direct the incoming calls destined for the telephone number of the local network on the RTC network in the direction of the telephone number of the cordless telephone in the GSM network. In this way, in the case of an incoming call to the local area network, the routing server directs the call towards the cordless telephone.

When the user removes the phone from his charger, the detection unit notices the absence of the phone and signals this to the base. This latter in this case calls the routing server in the RTC network and addresses to it a request to override the routing of the incoming calls.

Only certain incoming calls destined for the local area network could be directed towards the cordless telephone, for example only the calls originating from cordless telephones. Furthermore, one could in the opposite sense transmit at least certain of the incoming calls in the RTC network intended for the cordless telephone.

Instead of calling the steering server in the RTC network, it could be called in the GSM network insofar as the cordless phone is in its charger and thus connects the local network to the cordless network.

Furthermore, the radio base could comprise a steering unit intended to direct the outgoing calls made by a combined telephone of the local network towards one of the two networks, RTC 100 and the cordless 140 were sent as a function of predefined criteria (cost of communication, occupancy of the cordless network, etc.) when the cordless phone 120 in his charger 123 located.

In another variant, the local area network also comprises the following elements.

The charger integrates an interpreter configured to simulate the operation of a cordless telephone keypad in combination with the keyboard of a DECT wireless combo telephone paired with the DECT base. The interpreter is adapted to convert a command generated by actuating a keyboard key of the DECT combo telephone into a command simulating the operation of a key on the cordless telephone keypad. It thus allows to relocate the cordless telephone keypad to the DECT combi phone.

The DECT radio combo phones each have an internal call button that allows them to call another DECT wireless combo phone of the local area network, each DECT combo phone having an internal telephone number. An internal telephone number is also assigned to the DECT wireless combo telephone interface module, which is integrated in the charger.

When a user detects the internal telephone number of the combo telephone interface module using the keypad of a radio combo telephone and presses the internal call button, the subject combo telephone and the combo telephone interface module establish internal communication with each other through the base. From now on, thanks to the interpreter, the user can use the keypad of the radio combo telephone to control the cordless telephone. The interpreter receives commands generated by operating a key of the radio combo phone keypad and converts them into commands that simulate the operation of the keypad keyboard keys.

In this way, the user can access the various functions of the cordless telephone, such as polling a subscriber directory or voice mailbox, modifying the subscriber directory, sending SMS messages, and so on.

Instead of being integrated into the charger, the interpreter could be integrated in the base or the radio combination phone.

Instead of the AT commands you could use any other command type of this type.

Finally, instead of a radio combination telephone module, it was possible to provide a radio combination interface telephone which is not integrated in the charger and can be connected to the cordless telephone by radio or wire connection.
