1. A method for generating a Long Term Evolution (LTE) network return procedure, comprising:
initiating, by a mobile terminal, connection of the mobile terminal to an LTE network; receiving, by the mobile terminal from the LTE network, a system message including a signal strength threshold parameter and at least one of a first listing and a second listing, the first listing specifying a network-wide selection of LTE network access points, and the second listing specifying a subset of LTE network access points of the first listing; initiating, by the mobile terminal, a circuit-switched fallback algorithm to establish connection of the mobile terminal to a circuit-switched network (CSN); measuring, by the mobile terminal while connected to the CSN, signal strength of LTE network access points selected from one of the first listing and the second listing; generating, by the mobile terminal, a ranking of measured LTE network access points exhibiting signal strength at least greater than the signal strength threshold parameter and according to measured signal strength; initiating disconnection of the mobile terminal from the CSN; and generating, by the mobile terminal in absence of redirection instruction from the CSN, a packet-switched network return procedure that, when instantiated by the mobile terminal, implements connection of the mobile terminal to the LTE network based on the ranking of measured LTE network access points. |
