Abstract:
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 that the RSRP satisfies an RSRP threshold; comparing the RS-SINR to a signal-to-interference-and-noise ratio (SINR) threshold; and disconnecting from the first network and reselecting to a legacy network having a circuit switched domain when the RS-SINR does not satisfy the SINR threshold and the RSRP satisfies the RSRP threshold.
