Abstract: The embodiments herein relate to a method performed by a gateway. The gateway detects that a procedure for activating or deactivating a bearer has been initiated. The gateway receives a first modify bearer or modify access bearers request message for the same PDN connection and UE as the bearer activation or deactivation procedure is intended for. The gateway detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway and associated with said same PDN connection and UE. The gateway accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.

Abstract: A method (400) of controlling resource usage of adaptive streaming sessions for transmission via a Radio Access Network (RAN) is provided. The method comprises identifying (401) at least one adaptive streaming session, determining (402) available bitrates for the identified adaptive streaming sessions, determining (403) a resource allocation of the RAN, determining (404) a target bitrate for each of the identified adaptive streaming sessions, and throttling (405) each of the identified adaptive streaming sessions having a current bitrate which is larger than their respective target bitrate. The respective target bitrates are determined (404) based on the available bitrates and the current resource allocation of the RAN. In this way, an improved distribution of shared air interface resources of the RAN may be achieved. Further, a network node for controlling resource usage of adaptive streaming sessions for transmission via a RAN is provided.

Abstract: A user network (e.g., mobile phone) is described herein that uses one or more access systems to establish a communications session with a remote communications network.
