Abstract

An infrastructure and method for controlling wireless access to a telecommunications infrastructure for a device includes a first access grant time interval applicable for granting access for the device to the telecommunications infrastructure stored in a device register system. The first access grant time interval is applied when the device requests access to the telecommunications infrastructure via a first network node of the telecommunications infrastructure. However, a second access grant time interval is applied in a second network mode of the telecommunications infrastructure when the device requests access via the second network node. The second access grant time interval is applicable for granting access for the device to the telecommunications infrastructure and is different from the first access grant time interval.

First claim

The invention claimed is:

1. A method for controlling wireless access to a telecommunications infrastructure for a device, the method comprising:
storing a first access grant time interval applicable for granting access for the device to the telecommunications infrastructure in a device register system;
applying the first access grant time interval when the device requests access to the telecommunications infrastructure via a first network node of the telecommunications infrastructure;
storing a forbidden time interval in the device register system;
transferring the forbidden time interval from the device register system to a second network node of the telecommunications infrastructure;
selecting, via the second network node, a second access grant time interval so as to avoid an overlap with the forbidden time interval in the device register system; and
applying the second access grant time interval in the second network node of the telecommunications infrastructure when the device requests access to the telecommunications infrastructure via the second network node,
wherein the second access grant time interval is applicable for granting access for the device to the telecommunications infrastructure and is different from the first access grant time interval,
wherein the first network node and the device register system are located in a home network of the device and the second network node is located in a visiting network of the device.

2. The method according to claim 1 , further comprising:
transferring the first access grant time interval from the device register system to the second network node; and
obtaining the second access grant time interval in the second network node by adapting the first access grant time interval.

3. The method according to claim 1 , further comprising:
receiving an access request from the device at the second network node during the first access grant time interval and outside the second access grant time interval
forwarding the access request from the second network node to the device register system;
receiving an access grant message from the device register system at the second network node; and
rejecting the access request from the device by applying the second access grant time interval at the second network node.

4. The method according to claim 1 , further comprising:
transmitting to the device register system an information message regarding the second access grant time interval applied by the second network node.

5. A telecommunications infrastructure comprising:
a device register system configured to store, in non-transitory computer readable media, a first access grant time interval applicable for granting access for a device to the telecommunications infrastructure and a forbidden time interval;
a first network node configured to grant access during the first access grant time interval when the device requests access via the first network node; and
a second network node, wherein
the second network node comprises an access controlling system configured for applying a second access grant time interval to control access to the telecommunications infrastructure when the device requests access via the second network node, the second access grant time interval being applicable for granting access for the device to the telecommunications infrastructure and being different from the first access grant time interval, the access controlling system including:
an interface configured for receiving the forbidden time interval from the device register system, and
a processor configured to determine the second access grant time interval based on the received forbidden time interval so as to avoid an overlap with the forbidden time interval,

wherein the device register system and first network node are located in a home network of the device and the second network node is located in a visiting network of the device.

6. The telecommunications infrastructure according to claim 5 , wherein the access controlling system of the second network node comprises:
an interface configured for receiving the first access grant time interval from the device register system; and
a processor configured for obtaining the second access grant time interval in the second network node by adapting the first access grant time interval.

7. The telecommunications infrastructure according to claim 5 , wherein the access controlling system is configured for:
receiving an access request from the device during the first access grant time interval and outside the second access grant time interval;
forwarding the access request to the device register system;
receiving an access grant message from the device register system; and
rejecting the access request from the device by applying the second access grant time interval at the second network node.

8. The telecommunications infrastructure according to claim 5 , wherein the access controlling system is further configured for transmitting to the device register system an information message regarding the second access grant time interval applied by the second network node.

9. A visiting network for a device, the visiting network comprising a second network node of a telecommunications infrastructure, wherein the telecommunications infrastructure includes a device register system, a first network node, and the second network node, wherein the device register system is configured to store, in non-transitory computer readable media, a first access grant time interval applicable for granting access for the device to the telecommunications infrastructure and a forbidden time interval, wherein the first network node is configured to grant access during the first access grant time interval when the device requests access via the first network node, wherein the device register system and the first network node are located in a home network of the device, wherein the second network node comprises:
an access controlling system configured for applying a second access grant time interval to control access to the telecommunications infrastructure when the device requests access via the second network node, the second access grant time interval being applicable for granting access for the device to the telecommunications infrastructure and being different from the first access grant time interval, the access controlling system including:
an interface configured for receiving the forbidden time interval from the device register system, and
a processor configured to determine the second access grant time interval based on the received forbidden time interval so as to avoid an overlap with the forbidden time interval.

10. An access controlling system provided in at least one of a first network node or a second network node of a telecommunication infrastructure, wherein the telecommunication infrastructure comprises the first network node, the second network node, and a device register system, wherein the device register system is configured to store, in non-transitory computer readable media, a first access grant time interval applicable for granting access for a device to the telecommunications infrastructure and a forbidden time interval, wherein the first network node is configured to grant access during the first access grant time interval when the device requests access via the first network node, wherein the access controlling system is configured for applying a second access grant time interval to control access to the telecommunications infrastructure when the device requests access via the second network node, the second access grant time interval being applicable for granting access for the device to the telecommunications infrastructure and bein
