Abstract

A method, mobile radio station and computer program to perform a change of the mobile radio device category based on the state of the transportation vehicle. When the transportation vehicle is stopped, a lower mobile radio device category is selected, wherein the downlink and/or uplink data rates are reduced. This protects the battery of the transportation vehicle and improves the resource utilization in the mobile radio system.

First claim

The invention claimed is:

1. A mobile radio station included in a mobile radio system, the mobile radio station comprising:
at least one processor running software; and
a memory accessible by the software,
wherein the mobile radio station is installed in a transportation vehicle and the mobile radio station includes one or more operating states that relate to an operating state of the transportation vehicle, wherein the operating states of the transportation vehicle can include an Engine On, Engine Off, and “Relay” state,
wherein, when the operating state of the transportation vehicle is one of Engine On, Engine Off, and “Relay” and the transportation vehicle is parked, the mobile radio station is operated as a radio relay station,
wherein a plurality of mobile radio device categories are defined in the mobile radio system,
wherein, a mobile radio device category is assigned to the mobile radio station and is stored in a table in the memory,
wherein the assigned mobile radio device category is registered on the mobile radio station to communicate in the mobile radio system, wherein the registration specifies the assigned mobile radio device category for the mobile radio device,
wherein the mobile radio station monitors the operating state of the mobile radio station to determine whether a current operating state of the transportation vehicle has changed and, during operation, the mobile radio station determines-whether the assigned mobile radio device category matches the current operating state of the mobile radio station that relates to the operating state of the transportation vehicle,
wherein the mobile radio station is logged out of the mobile radio base station in response to a difference between the assigned-mobile radio device category and the current operating state of the mobile radio station that relates to the operating state of the transportation vehicle,
wherein the mobile radio station is, thereafter, re-registered on the mobile radio base station in the mobile radio system with specification of a second assigned mobile radio device category, and
wherein the memory further includes a register location in a register area, wherein the current operating state of the mobile radio station that relates to the operating state of the transportation vehicle is registered in an entry in the register location, and wherein the entry is updated in response to detection of a change of operating state of the transportation vehicle.

2. The mobile radio station of claim 1 , wherein the memory also includes a second register location in the registration area, and wherein the current mobile radio device category is registered in an entry in the second register location.

3. The mobile radio station of claim 1 , wherein the check as to whether the assigned mobile radio device category still matches the current operating state of the transportation vehicle is carried out in response to detection of the change of operating state of the transportation vehicle.

4. The mobile radio station of claim 1 , wherein the check as to whether the assigned device category still matches the change of operating state of the transportation vehicle is carried out continuously in operation, repeated intermittently, or repeated with a specific time interval.

5. The mobile radio station of claim 2 , wherein the entry in the second register location is updated in the process of de-registration and re-registration of the mobile radio station on the mobile radio base station.

6. The mobile radio station of claim 1 , wherein at least the operating states “Engine On” and “Standby” are distinguished for the registration, wherein a variation of the 3GPP LTE mobile radio standard family is used as the mobile radio system, and wherein a mobile radio device category of “Category 6” or above, corresponding to “mobile broad band MBB”, is provided for the “Engine On” operating state, and wherein a mobile radio device category with inferior transmission properties than “Category 6” is provided for the “Standby” operating state of the transportation vehicle.

7. The mobile radio station of claim 1 , wherein a variation of the 3GPP mobile radio standard family is used as the mobile radio system, and wherein the mobile radio device category “Category M1” corresponding to “machine type communication MTC” is provided for the “Engine Off” operating state, and wherein a mobile radio device category of “Category 6” or above, corresponding to “mobile broad band MBB”, is provided for the operating states “Engine On” and “Relay”.

8. The mobile radio station of claim 1 , wherein the assignment of one or more operating states to a mobile radio device category is extracted from the table in the memory of the mobile radio station.

9. A method for operating a mobile radio station in a mobile radio system, the method comprising:
providing a memory accessible by software included in the mobile radio station,
defining a number of mobile radio device categories in the mobile radio system,
registering the mobile radio station on a mobile radio base station for communication in the mobile radio system the registration specifying mobile radio device category that is assigned to the mobile radio station,
installing the mobile radio station in a transportation vehicle, the transportation vehicle including a number of operating states including Engine On, Engine Off, and Relay, and the mobile radio station including a number of operating states that correspond to the operating state of the transportation vehicle,
monitoring the mobile radio station to determine whether the operating state of the transportation vehicle changes,
checking, during operation, whether the mobile radio device category assigned to the mobile radio station matches the current operating state of the transportation vehicle,
logging the mobile radio station out of the mobile radio base station if the mobile radio device category assigned to the mobile radio station does not match the current operating state of the vehicle,
re-registering the mobile radio station on the mobile radio base station by specifying a second mobile radio device category,
registering the current operating state of the transportation vehicle in an entry in a register location in a register area of the memory, wherein the entry is updated in response to detection of a change of operating state of the transportation vehicle,
distinguishing at least the operating states “Engine On” and “Engine Off” during the registering, installing and checking steps, and
distinguishing at least the operating state “Relay”, in which the parked transportation vehicle is operated as a mobile radio relay station, as an additional operating state for the registering, installing and checking steps.

10. The method of claim 9 , wherein the step of checking as to whether the assigned mobile radio device category matches the current operating state is carried out in response to detection of the change of operating state.

11. The method of claim 9 , wherein the step of checking as to whether the assigned device category matches the current operating state is carried out continuously in operation or repeated intermittently or repeated with a specific time interval.

12. The method of claim 10 , wherein an entry in a second register location in the register area of the memory where the mobile radio device category is registered is updated in the process of de-registration and re-registration of the mobile radio station on the mobile radio base station.

13. The method of claim 9 , wherein at least the operating states “Engine On” and “Standby” are distinguished for the registration, wherein a varia
