Abstract:
1. A method comprising: setting up a policy controlled bearer service for delivery of a service from an application function in a service network to a mobile radio terminal where the service is delivered to the mobile radio terminal over a radio interface by a radio network coupled to a core network which is coupled to the service network, wherein the setting up of the policy controlled bearer service, comprises: registering a terminal identity of the mobile radio terminal associated with policy identifying information in a register of a policy decision function; receiving a Packet Data Protocol (PDP) activation request from the terminal to establish a PDP context between the mobile radio terminal and the core network, via a core network node, wherein the PDP context activation request includes the mobile radio terminal identity and a set of requested quality of service (QoS) parameters for the PDP context; binding the PDP context activation request to the policy identifying information by the mobile radio terminal identity to determine applicable policy information for the PDP context; performing a policy check by checking if the requested QoS parameters fulfill said applicable policy information; and sending a PDP context accept message to the core network node to initiate completion of the PDP context set-up if the policy check was successful, wherein the set of requested quality of service (QoS) parameters for the PDP context includes QoS parameters for communication with the mobile radio terminal over the radio interface.
