Claim:
1. In a communication system comprising a Long Term Evolution (LTE) network configured to serve user equipment devices (UEs) over a first air interface, a legacy network configured to serve UEs over a second air interface, and a communication interface between the LTE network and the legacy network, a method comprising: providing a circuit-switched fallback (CSFB) service that enables UEs being served by the LTE network to engage in signaling with the legacy network via the LTE network; detecting on the first air interface a threshold high level of signaling associated with the CSFB service; and responsive to detecting on the first air interface the threshold high level of signaling associated with the CSFB service, directing one or more UEs being served by the LTE network to refrain from using the CSFB service, wherein each of the one or more UEs is selected based on whether the UE is capable of using single-radio-LTE (SRLTE) when CSFB is not available.
