Abstract
Example embodiments presented herein are directed towards a mobility management node and a communications node, and corresponding methods therein, for the handling of a RAN congestion status. The example embodiments presented herein allow for a means of providing an accurate RAN congestion status in an efficient manner.
Claims22
A method, in a mobility management node, for Radio Access Node, RAN, congestion status handling, the method comprising:
- receiving, from a communications node, a communication regarding a wireless device served by a RAN node, the communication comprising a received RAN congestion status;
- comparing the received RAN congestion status with a saved RAN congestion status, the saved RAN congestion status being saved within the mobility management node prior to the receiving;
- and
- if a congestion level of the received RAN congestion status is different than a congestion level of the saved RAN congestion status, forwarding, to a core network node or a RAN Congestion Awareness Function, RCAF, a current RAN congestion status associated with the wireless device in a cell currently serving the wireless device, wherein the current RAN congestion status is either the received RAN congestion status or the saved RAN congestion status.
A mobility management node for Radio Access Node (RAN) congestion handling, the mobility management node comprising:
- a receiver configured to receive, from a communications node, a communication regarding a wireless device served by a RAN node, the communication comprising a received RAN congestion status;
- processing circuitry configured to compare the received RAN congestion status with a saved RAN congestion status, the saved RAN congestion status being saved within the mobility management node prior to the receiving the communication;
- and
- if a congestion level of the received RAN congestion status is different than a congestion level of the saved RAN congestion status, a transmitter configured to forward, to a core network node or a RAN Congestion Awareness Function, RCAF, a current RAN congestion status associated with the wireless device in a cell currently serving the wireless device, wherein the current RAN congestion status is either the received RAN congestion status or the saved RAN congestion status.
A method, in a communications node, for Radio Access Node, RAN, congestion status handling, the method comprising:
- sending, to a mobility management node, a communication regarding a wireless device served by a RAN node, wherein said communication is utilized for RAN congestion status handling within the mobility management node during a wireless device mobility procedure and/or when the wireless device is in a connected state for a time period, wherein if the communications node is a RAN node the mobility management node is a Gn/Gp Serving General Packet Radio Service Support Node, Gn/Gp SGSN or a S4-SGSN.
A communications node for Radio Access Node, RAN, congestion status handling, the communications node comprising:
- a transmitter configured to send, to a mobility management node, a communication regarding a wireless device served by a RAN node, wherein said communication is utilized for RAN congestion status handling within the mobility management node during a wireless device mobility procedure and/or when the wireless device is in a connected state for a time period, wherein if the communications node is a RAN node the mobility management node is a Gn/Gp Serving General Packet Radio Service Support Node, Gn/Gp SGSN or a S4-SGSN.
