Abstract
A user equipment configured to operate in a Long Term Evolution (LTE) network. The user equipment comprises transceiver circuitry that operates the user equipment in either of two modes, the two modes comprising: i) a first mode in which the transceiver circuitry performs packet data services in the LTE network and performs voice calls in the LTE network using a Voice over LTE (VoLTE) service; and ii) a second mode in which the transceiver circuitry performs packet data services in the LTE network and performs voice calls in a legacy network. The user equipment also comprises a controller that compares a link quality associated with a radio link to the LTE network to at least one threshold value and, in response to the comparison, controls switching the user equipment between the first mode and the second mode. The controller switches the user equipment from the first mode to the second mode if the link quality falls below a first drop threshold value associated with an RSRP value or an SINR value. The controller switches the user equipment from the first mode to the second mode if the link quality falls below the first drop threshold value for more than a drop period of time thres…
