FIELD: radio engineering, communication.
SUBSTANCE: method and a wireless device for controlling a unidirectional EPS channel, a method and a base radio station for setting parameters of the unidirectional S1-channel or the unidirectional Iu-channel, and a method and the second network node for controlling a unidirectional EPS channel are disclosed. The wireless device sends, to the second network node, a request to establish a unidirectional EPS channel for the service. The request is associated with the required connectivity for the service. The required level refers to the probability of maintaining connectivity towards the first network node. The second network node further receives the required connectivity for the service. The second network node sends, to the base radio station, a request for setting parameters of the unidirectional S1-channel or the unidirectional Iu-channel.
EFFECT: improving the service quality.
