Abstract

A method for network reselection by a wireless communication device is provided. The wireless communication device can have an established connection to a first network. The method can include measuring a signal strength and a signal-to-noise ratio of the first network. The method can further include determining that the signal strength satisfies a signal strength threshold. The method can additionally include comparing the signal-to-noise ratio to a signal-to-noise ratio threshold. The method can also include disconnecting from the first network and reselecting to a second network in an instance in which the signal-to-noise ratio does not satisfy the signal-to-noise ratio threshold even though the signal strength satisfies the signal strength threshold.

First claim

What is claimed is:

1. A method for network reselection by a wireless communication device, the method comprising:
measuring a reference signal receive power (RSRP) and a reference signal signal-to-interference-and-noise ratio (RS-SINR) of a first network, wherein the wireless communication device has an established connection to the first network, and wherein the first network operates in accordance with a Long Term Evolution (LTE) wireless communication protocol;
determining t…
