A method for connecting a call coming into first wireless communication device to a terminal apparatus that can be operated as a wireless terminal apparatus of this wireless communication device and as a mobile radiotelephone terminal apparatus of a mobile radiotelephone network, under the precondition that the current availability of the terminal apparatus in the mobile radiotelephone network and/or in the wireless communication device is stored in both systems. It is checked whether there is present an item of information concerning the availability of the terminal apparatus via the mobile radiotelephone network and, if so, the call coming into the wireless communication device is forwarded to the terminal apparatus in the mobile radiotelephone network, if a delivery is not possible in the wireless communication device.

Method for connecting an incoming call in a wireless telecommunications installation to a dual mode terminal

An arrangement and a method with which wireless terminal devices which can usually be reached via a call number of one individual network computer can also be reached when they are located in the wireless communication area of a base station that is connected to another network computer. To this end, connection information is retrieved via a mobility server, and a connection setup to a corresponding network computer in whose radio area the wireless terminal device is located is controlled via that mobility server. The wireless terminal device delivers information, which is transmitted to the mobility server and from which, together with additional information from the network computer or the base station, this server is able to derive the information for the connection setup to the wireless terminal device. In order to limit the utilized network computers to only a switching function, performance features of the wireless terminal device are realized via a performance feature server, which controls the corresponding network computer via a CTI interface. The mobility servers are likewise connected to the respective network computers via a CTI interface. In this way, it is possible to realize private wireless communication networks with DECT functionality and with a large coverage, in which networks it is possible to reach wireless terminal devices at will, though they are dialed simply via the call number of a single network computer allocated to them.

Method and arrangement for wireless communication by means of at least two network computers

A method for restoring subscriber-related information in a database system of a communication network wherein, to restore subscriber-related information in a first database system of a first communication network for subscribers which are registered as subscribers both in the first communication network and in a second communication network, a second database system for storing subscriber data records containing subscriber-related information, and a controller for storing the subscriber-related information from the subscriber data records of the databases of a number of cordless communication systems in a storage device, are provided in the second communication network. The controller is also used for transferring subscriber-related information requested by the first database system to the first communication network.

Method to restore subscriber related information in a communication network data base system

A method for indicating the presence of a text message in a mobile radiotelephone network if the recipient is registered as a subscriber both in the mobile radiotelephone network and in another communication network as a subscriber. It is provided that the availability of the subscriber in the other communication network is stored in the database, which is allocated to the subscriber, of the mobile radiotelephone network, and in wherein message central module communicates a message concerning the presence of a text message for the subscriber to a control module of the other communication network (PISN), and wherein this control module thereupon causes the displaying of an item of information concerning the presence of a text message in the message central module of the mobile radiotelephone network to a terminal apparatus allocated to the subscriber within the other communication network.

Method for indicating that a text message is present in a message central module of a mobile radiotelephone network

System for the bidirectional connection of an ELAN and a CLS wide-area network (CLSnet) having an address memory for allocated MAC addresses of the ELAN (ELAN,, . . . ) and E.164 addresses of the CLS network (CLSnet), having a memory for an E.164 address allocated to the transition to the CLS network (CLSnet), and having a controller in order, dependent on specific conditions, to handover frames coming from the ELAN to the interface to the CLS network in common with the E.164 address belonging to the destination MAC address or, respectively, to discard them, whereby frames having a local broadcast MAC address as destination address are always to be discarded, and in order to hand frames coming from the wide-area network over to the interface to the ELAN.

System (IWF) for the bidirectional connection of an ELAN and a CLS wide-area network

A method for restoring subscriber-related or terminal equipment-related information in the databank system of a mobile radiotelephone network, wherein a control means of a first communication network always communicates subscriber-related or, respectively, terminal equipment-related information to the databank system of the mobile radiotelephone network whenever a subscriber or its terminal equipment can be reached for the first time within the first communication network. The control means also communicates this information to the databank system when more than a defined time duration has elapsed since the last communication of these information.
