Method and system for addressing an error condition associated with a service that enables user equipment devices being served by a first access network to engage in signaling with a second access network

摘要

In accordance with the disclosed methods and systems, while providing a service that enables user equipment devices (UEs) being served by a first network to engage in signaling with a second network via the first network, a controller or other network entity may detect an error condition associated with the service, such as a threshold-high level of signaling or an interface failure. In response to detecting the error condition, base stations in the first network may then direct one or more UEs being served by the first network to refrain from using the given service. As a result, the one or more UEs may refrain from using the given service and may instead use another approach to engage in signaling with the second network, which may enable the one or more UEs to circumvent the error condition until it gets remedied.

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.
