Method for determining a sequence of events, a determination device for determining a sequence of events, and a providing device

1. A method for determining, in a determination device, a sequence of events including a first event in a mobile communication network system, the method comprising the determination device:

identifying at least one second event before and/or after the first event;

determining a probability of an occurrence of each second event before and/or after the first event;

determining a probability of an occurrence of each second event before and/or after each other second event; and

determining a sequence of first and second events with the highest probability;

wherein the first and/or second events are provided by a providing device.

2. The method of claim 1 , further comprising determining a cause for the first event based on the sequence of first and second events with the highest probability.

3. The method of claim 1 , wherein the first event is a negative type of event and the second events are each a negative or positive type of event.

4. The method of claim 3 , wherein the negative type and/or positive type of event is one of a predetermined relevant type.

5. The method of claim 3 , wherein the negative type of event is: an abnormal call termination, a performance indicator event, and/or a failed process event.

6. The method of claim 1 , wherein the at least one second event is identified within a predetermined time before and/or after the first event.

7. The method of claim 1 , wherein the probability of the occurrence of the at least one second event before the first event is determined separately from the probability of the occurrence of the at least one second event after the first event.

8. The method of claim 1 , wherein the probability of the occurrence of the at least one second event before the first event is determined differently from the probability of the occurrence of the at least one second event after the first event.

9. The method of claim 1 , wherein the sequence of first and second events is determined including all combinations of first and second events.

10. The method of claim 1 , wherein the sequence of first and second events is determined including one specific order of first and second events.

11. The method of claim 1 :

wherein the negative type of the first and/or second event is:

a failed connection set up between a base station and a user terminal;

a failed connection set up between a base station and a network node;

a failed hand over of a user terminal between base stations;

a failed signal transfer for communication; or

a failed signal transfer for controlling a base station; and

wherein the positive type of the second event is:

a successful connection set up between a base station and a user terminal;

a successful connection set up between a base station and a network node;

a successful hand over of a user terminal between base stations;

a successful signal transfer for communication; or

a successful signal transfer for controlling a base station.

12. A determination device for determining a sequence of events including a first event in a mobile communication network system, the determination device comprising:

processing circuitry;

memory containing instructions executable by the processing circuitry whereby the determination device is operative to:

identify at least one second event before and/or after the first event;

determine a probability of an occurrence of each second event before and/or after the first event;

determine a probability of an occurrence of each second event before and/or after each other second event; and

determine a sequence of first and second events with the highest probability.

13. The determination device of claim 12 , wherein the instructions are such that the determination device is operative to determine a cause for the first event based on the sequence of first and second events with the highest probability.

14. A providing device in a communication network system, the providing device comprising:

detector circuitry configured to detect a first and/or second event, wherein the first event is a failed process, and wherein the second event is either a successful process or a failed process;

processing circuitry;

memory containing instructions executable by the processing circuitry whereby the providing device is operative to:

provide information indicating the first and/or second event to the communication network system or an external entity processing the first and/or second event to determine:

a cause of the first event;

a probability of an occurrence of the second event before and/or after the first event;

a probability of an occurrence of the second event before and/or after each of one or more other second events; and

a sequence of first and second events with the highest probability.

15. The providing device of claim 14 , wherein the providing device is: a mobile terminal, a base station, a network node, a network entity, and/or external equipment associated with the communication network system.

16. A non-transitory computer readable recording medium storing a computer program product for determining, in a determination device, a sequence of events including a first event in a mobile communication network system, the computer program product comprising software instructions which, when run on processing circuitry of the determination device, causes the determination device to:

identify at least one second event before and/or after the first event;

determine a probability of an occurrence of each second event before and/or after the first event;

determine a probability of an occurrence of each second event before and/or after each other second event; and

determine a sequence of first and second events with the highest probability;

wherein the first and/or second events are provided by a providing device.
