## Abstract

A method and a system with which a primary user, in particular a mobile radio operator, can make a part of the radio spectrum range which is reserved exclusively for the mobile radio operator available in localized and/or time-restricted fashion to a local end user who requested the restricted usage authorization of the radio spectrum range using registered credentials at the mobile radio operator. By way of the credentials the mobile radio operator can allow the local end user limited usage of that radio spectrum range in fee-bearing fashion and can bill same. The local user can then use the assigned frequency band in accordance with his own needs. In particular the user can wirelessly transmit signals in the assigned frequency range between end devices to which no credentials are allocated and in that situation use a transmission protocol which is not defined for the mobile radio network.

## Claims

### Claim 1

A method for the coordinated use of mobile radio frequencies, wherein a primary user has an exclusive usage right for a first radio frequency range, comprising the steps:
registration of an end user for identification of the end user on the basis of credentials at the primary user,
request from the end user to the primary user for a time-restricted and/or location-restricted usage of a portion of the first radio frequency range, wherein the request includes a definition of the requested restricted usage and statement of the registered credentials of the end user,
matching the requested usage with already granted access rights in a central database of the primary user and selection of a frequency band which is not otherwise allocated,
detection of the allocation of the selected frequency band and the data for definition of the time-restricted and/or location-restricted usage and the associated credentials in the central database of the primary user,
communication of an allocation information which defines the restricted usage inclusive of the selected frequency band from the primary user to the end user,
development of a private network by the end user, wherein the private network includes at least one private base station and at least one end device as components of the private network,
wherein the at least one end device does not have credentials registered at the primary user, and
wherein the at least one end device performs a wireless signal transmission, wherein at least a part of the selected frequency band is used, and
wherein the components of the private network are so configured that a wireless signal transmission is effected corresponding to the restricted usage defined by the allocation information.

### Claim 2 (depends on 1)

The method for the coordinated use of mobile radio frequencies as set forth in claim 1, wherein the primary user is a mobile network operator (MNO).

### Claim 3 (depends on 2)

The method for the coordinated use of mobile radio frequencies as set forth in claim 2, wherein the mobile radio operator has defined protocols in accordance with which it supports a mobile communication within the first radio frequency range, and
wherein in the wireless transmission within the private network a transmission protocol is used, that does not correspond to the protocols defined by the mobile network operator.

### Claim 4 (depends on 1)

The method for the coordinated use of mobile radio frequencies as set forth in claim 1,
wherein the request is effected by way of a connection and the communication of the allocation information is effected by way of the connection.

### Claim 5 (depends on 1)

The method for the coordinated use of mobile radio frequencies as set forth in claim 1, wherein the private network has a private core which implements resource distribution for the wireless transmission within the private network.

### Claim 6 (depends on 1)

The method for the coordinated use of mobile radio frequencies as set forth in claim 1, wherein the primary user uses the credentials received with the request to bill the end user costs for the allocated restricted usage.

### Claim 7 (depends on 1)

The method for the coordinated use of mobile radio frequencies as set forth in claim 1, wherein the at least one end device includes means which prevent the at least one end device implementing usage of radio frequencies outside the allocated restricted usage.

### Claim 8

A private core for a coordinated use of mobile radio frequencies in a private network,
wherein a primary user has an exclusive usage right for a first radio frequency range, and
wherein the private core has credentials with which an end user is registered with the primary user for identification of the end user, and
wherein the private core has an interface in order to make a request for a time-restricted and/or location-restricted usage of a part of the first radio frequency range by way of a connection to an MNO core network of the primary user, and
wherein the request includes a definition of the requested restricted usage and the statement of the registered credentials of the end user, and
wherein the private core is adapted to receive by way of the connection an allocation information from the MNO core network which defines the restricted usage inclusive of a frequency band selected from the MNO core network, and
wherein the private network includes at least one private base station and at least one end device as components of the private network, and
wherein the at least one end device does not have credentials registered with the primary user, and
wherein the private core is adapted to configure the components of the private network, and
wherein the private core so configures the components of the private network that a wireless signal transmission is effected corresponding to the restricted usage defined in the allocation information, and
wherein the at least one end device performs a wireless signal transmission, wherein at least a part of the selected frequency band is used.

### Claim 9 (depends on 8)

The private core for the coordinated use of mobile radio frequencies as set forth in claim 8, wherein the primary user is a mobile network operator (MNO).

### Claim 10 (depends on 9)

The private core for the coordinated use of mobile radio frequencies as set forth in claim 9, wherein the mobile radio operator has defined protocols in accordance with which it supports a mobile communication within the first radio frequency range, and
wherein in the wireless transmission within the private network a transmission protocol is used, that does not correspond to the protocols defined by the mobile network operator.

### Claim 11 (depends on 8)

The private core for the coordinated use of mobile radio frequencies as set forth in claim 8, wherein the at least one end device includes means which prevent the at least one end device implementing usage of radio frequencies outside the allocated restricted usage, and wherein the private core is adapted to configure said means.

### Claim 12

An MNO core network of a primary user which has an exclusive usage right for a first radio frequency range,
wherein the MNO core network is adapted by way of a connection to receive requests from a private core for a time-restricted and/or location-restricted usage of a part of the first radio frequency range,
wherein the request includes a definition of the requested restricted usage and the statement of the registered credentials of an end user at the primary user,
wherein the MNO core network is adapted to match the requested usage with already granted access rights in a central database of the primary user and to select a frequency band which is not allocated elsewhere,
wherein the MNO core network is adapted to detect the allocation of the selected frequency band and the data for definition of the time-restricted and/or location-restricted usage and the associated credentials in the central database of the primary user,
wherein the NMO core network is adapted to communicate an allocation information which defines the restricted usage inclusive of the selected frequency band to the private core by way of the connection.
