Abstract
Systems and methods for generating a Long Term Evolution network return procedure. A mobile terminal may generate, in absence of redirection instruction from a circuit-switched network, a Long Term Evolution network return procedure that, when instantiated by the mobile terminal, implements connection of the mobile terminal to a Long Term Evolution network based on measured signal strength of at least one Long Term Evolution network access point.

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, 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 set of LTE network access points of the first listing;
- initiating, by the mobile terminal, connection of the mobile terminal to a circuit-switched network (CSN) for access to a particular circuit-switched service;
- determining, by the mobile terminal while connected to the CSN, availability of a third listing supplied by the CSN;
- measuring, by the mobile terminal while connected to the CSN, signal strength of at least one LTE network access point selected from one of the first listing, the second listing, and the third listing;
- initiating disconnection of the mobile terminal from the CSN for discontinued access to the particular circuit-switched service;
- 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 measured signal strength of the at least one LTE network access point.
A computer-implemented method, comprising:
- receiving, by a user equipment from a Long Term Evolution (LTE) network, 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 set of LTE network access points of the first listing;
- initiating, by the user equipment, connection of the user equipment to a circuit-switched network (CSN) for access to a particular circuit-switched service;
- determining, by the user equipment while connected to the CSN, availability of a third listing supplied by the CSN;
- measuring, by the user equipment while connected to the CSN, signal strength of at least one LTE network access point selected from one of the first listing, the second listing, and the third listing;
- and
- initiating, by the user equipment, connection of the user equipment to the LTE network based on the measured signal strength of the at least one LTE network access point.
A multi-mode mobile user equipment (UE), comprising:
- a processing unit;
- and
- a system memory connected to the processing unit, the system memory including instructions that, when executed by the processing unit, cause the processing unit to instantiate at least one module to generate a Long Term Evolution (LTE) network return procedure, the at least one module configured to:
- initiate connection of the UE to an LTE network;
- receive, from the LTE network, 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 set of LTE network access points of the first listing;
- initiate connection of the UE to a circuit-switched network (CSN) for access to a particular circuit-switched service;
- determine, while connected to the CSN, availability of a third listing supplied by the CSN;
- measure, while connected to the CSN, signal strength of at least one LTE network access point selected from one of the first listing, the second listing, and the third listing;
- and
- generate, in absence of redirection instruction from the CSN, a packet-switched network return procedure that, when instantiated by the UE, implements connection of the UE to the LTE network based on the measured signal strength of the at least one LTE network access point.
