A mobile station for transmitting a mobile radio signal to a base station has a memory device in which a number of available applications are stored which can relate to different &ldquo;carriers,&rdquo; i.e., mobile radio network systems or service providers within a single mobile radio network. A selection device of the mobile station calculates expected charges for a desired connection for each of these applications which are being considered for the transmission connection. Based upon the calculations, the most cost-efficient application for the desired transmission is selected. The actual transmission of the communication data for the base station is then carried out on the basis of this application.

Mobile station having a cost-efficient call management method and system

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.

Method for restoring subscriber or terminal equipment information in the

A method for the implementation of a connection handover initiated by a cordless terminal equipment in Detect systems with modified standard: After the signaling of the call setup request signal 'Connection Hand Over Request', the mobile part also immediately transmits the user data in the newly captured channel. After reception of the 'Connection HO Request' forwarded by the newly selected base station, reception in the switching node can therefore be immediately switched thereto (without a gap in the user data transmission). In the transmission direction, the switching equipment can transmit in parallel via both base stations until, for example, an acknowledgment is received from the new base station with respect to the error-free signal output of 'Bearer Confirm', or until the mobile part clears down the previous connection.

Method for connection handling in communication systems with wireless

A method for operating a wireless telephone system to provide emergency service for a wireless telephone operating in the wireless telephone system. In the present invention, the wireless telephone system receives a request to connect the wireless phone to a predetermined telephone number from the wireless telephone. The telephone system then queries the wireless telephone for a unique identifying number identifying the wireless telephone. The unique identifying number enables the wireless telephone system to connect the wireless telephone to the wireless telephone system. The wireless telephone system maintains a set of direct inward dialing numbers (DIDs) that are used exclusively for emergency calls. Each of the DID allows a caller outside of the wireless telephone system to direct a call to a telephone within the wireless telephone system. The emergency call is assigned one of these DIDs and that DID is linked to the unique identifying number of the telephone placing the emergency call. The wireless telephone is then connected to an emergency operator and the emergency operator is given the assigned DID. The DID enables a call from the emergency operator to the wireless telephone through the wireless telephone system. In one embodiment of the present invention, the DID assigned to the wireless telephone also identifies the antenna closest to the wireless telephone. The assignment between the DID and the unique identifying number is terminated after a predetermined period of time which may be altered by the caller or those servicing the emergency call.

Method for allowing a mobile phone to receive a call through a wireless

A method for flow control of data exchanged via nodes connecting an origin and a destination to one another, in which the nodes are arbitrarily meshed within a data network and are connected to one another via lines and every node is equipped with a transmission memory and a reception memory device, includes the cyclical transmission of a first control signal (FCM1) in a prescribed time sequence and, as needed, a second control signal (FCM2) dependent on a data quantity within a time cycle which exceeds the quantity of data usually transmitted, these control signals being forwarded to the respectively adjacent nodes in case of unimpeded data transmission. In the jam condition, these flow control signals, (FCM1, FCM2) are omitted or modified and, after recognition by the respective nodes effect the inhibition of the corresponding transmission memory means (SS) at such node.
