Congestion monitoring of mobile entities
First Claim
1. A method, by a Policy and Charging Rules Function (PCRF) of a mobile communications network, to control a signaling of congestion information of mobile entities at a plurality of Radio Access Network Congestion Awareness Functions (RCAFs) that monitor which mobile entities are affected by a congestion in a radio access network of the mobile communications network, the method comprising:
- receiving, from one of the RCAFs, an indication that one of the mobile entities is affected by a congestion;
storing said one RCAF from which the indication is received as the current RCAF for said one mobile entity;
receiving, from another RCAF, the indication that said one mobile entity is affected by a congestion; and
indicating to the current RCAF, in response to the indication received from the another RCAF, a release of congestion information relating to said one mobile entity.

Abstract
A method, by a policy control unit of a mobile communications network, to control a signalling of congestion information of mobile entities at a plurality of congestion monitoring units that monitor which mobile entities are affected by a congestion state in a radio access network of the mobile communications network. The method comprises receiving, from one of the congestion monitoring units, an indication that one of the mobile entities is affected by a congestion, storing said one congestion monitoring unit from which the indication is received as the current congestion monitoring unit for said one mobile entity, receiving, from another congestion monitoring unit, the indication that said one mobile entity is affected by a congestion, and indicating, in response to the indication received from the other monitoring unit, to the current congestion monitoring unit a release of congestion information relating to said one mobile entity.

10. A Policy and Charging Rules Function (PCRF) configured to control a signalling of congestion information of mobile entities at a plurality of Radio Access Network Congestion Awareness Functions (RCAFs) that monitor which mobile entities are affected by a congestion in a radio access network of the mobile communications network, the PCRF comprising:
-
a receiver configured to receive, from one of the RCAFs, a first indication that one of the mobile entities is affected by a congestion; a database configured to store said one RCAF from which the first indication is received as the current RCAF for said one mobile entity; a transmitter; and a processing circuit; wherein the processing circuit is configured to use the transmitter to indicate to the current RCAF to release congestion information relating to said one mobile entity in response to the received first indication, when the receiver receives the first indication that said one mobile entity is affected by a congestion from another RCAF.

11. A method to operate a Radio Access Network Congestion Awareness Function (RCAF) that monitors which mobile entities are affected by a congestion in a radio access network of a mobile communications network, the method comprising:
-
sending, to a Policy and Charging Rules Function (PCRF) of the mobile communications network, an indication that one of the mobile entities is affected by a congestion; receiving, from the PCRF of the mobile communications network, an indication to release congestion information relating to said one mobile entity; and releasing the congestion information for said one mobile entity in response to the received indication. - View Dependent Claims (12, 13)

14. A Radio Access Network Congestion Awareness Function (RCAF) configured to monitor which mobile entities are affected by a congestion in a radio access network of a mobile communications network, the RCAF comprising:
-
a transmitter configured to send, to a Policy and Charging Rules Function (PCRF) of the mobile communications network, an indication that one of the mobile entities is affected by a congestion, a receiver configured to receive, from the PCRF of the mobile communications network, an indication to release congestion information relating to said one mobile entity, and a processing circuit configured to release the congestion information for said one mobile entity in response to the received indication.

15. A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising instructions that, when executed by at least one processing circuit in a Policy and Charging Rules Function (PCRF) of a mobile communications network, cause the at least one processing circuit to control a signalling of congestion information of mobile entities at a plurality of Radio Access Network Congestion Awareness Functions (RCAFs) that monitor which mobile entities are affected by a congestion in a radio access network of the mobile communications network by:
-
receiving, from one of the RCAFs, an indication that one of the mobile entities is affected by a congestion; storing said one RCAF from which the indication is received as the current RCAF for said one mobile entity; receiving, from another RCAF, the indication that said one mobile entity is affected by a congestion; and indicating to the current RCAF, in response to the indication received from the another RCAF, a release of congestion information relating to said one mobile entity.

16. A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising instructions that, when executed by at least one processing circuit in a Radio Access Network Congestion Awareness Function (RCAF) that monitors which mobile entities are affected by a congestion in a radio access network of a mobile communications network, cause the at least one processing circuit to:
-
send, to a Policy and Charging Rules Function (PCRF) of the mobile communications network, an indication that one of the mobile entities is affected by a congestion; receive, from the PCRF of the mobile communications network, an indication to release congestion information relating to said one mobile entity; and release the congestion information for said one mobile entity in response to the received indication.
