A method of operation in a wireless communication system comprises establishing by a UE over a cellular communications access network, a Quality of Service QoS flow, for an incoming Internet Protocol Multimedia Subsystem (IMS) session. The UE triggers over an untrusted non-3GPP access network, another IMS registration request along with requesting an IP address of the UE. The request includes an internet service provider (ISP) identifier of the untrusted access network. A network node transfers the incoming IMS session to the QoS flow established for the incoming IMS session to the untrusted access network being accessed by the UE. Thereafter, the IMS reports details of calls availed by the UE through the untrusted access network to a remote server.
A method performed by a control device for controlling total average transmission power of a radio base station. The method comprises performing, for a current discrete time value, control of total average transmission power according to an average power control loop and subject to an upper threshold value. The total average transmission power is computed over an averaging time window T of a present value of momentary transmission power and N−1 preceding values. This is controlled to not exceed the threshold value by a resource threshold factor that limits the momentary transmission power and by for at least one future discrete time value less than, or equal to, t+T predicting a future value of the total average transmission power for a future assumed resource threshold factor. The method comprises gradually changing this factor as a function of a present state of the control loop.
