A method comprising: a policy charging and rules function (PCRF) receiving from an Internet Multimedia Subsystem (IMS) platform a message indicating that a new bearer is needed for an IMS-based session being set up for a user equipment device (UE), wherein the message received by the PCRF from the IMS platform includes a base station identifier of the base station that is serving the UE; and in response to the PCRF receiving from the IMS platform the message that indicates the new bearer is needed for the IMS-based session being set up with the UE and that includes the base station identifier of the base station that is serving the UE, (i) the PCRF using the base station identifier as a basis to determine a level of congestion of the base station serving the UE, (ii) the PCRF using the determined level of congestion of the base station serving the UE as a basis to select a quality of service (QoS) level to be used for the new bearer, and (iii) the PCRF invoking use of the selected QoS level for the new bearer, wherein the selected QoS level for the new bearer defines for the new bearer one or more QoS parameters including a parameter selected from the group consisting of priority level, maximum packet delay, maximum packet loss rate, and minimum bit rate.
