Claim Text:
1. A method for use in a mobile communication device, the method comprising: establishing, at the mobile communication device, a wireless link to a Long Term Evolution (LTE) network; tuning, at a first time point, a transceiver of the mobile communication device away from the LTE network and to a 3GPP2 Code Division Multiple Access (CDMA) 2000 network; re-tuning, at a second time point, the transceiver back to the LTE network; determining, using a timer of the mobile communication device, an amount of time elapsed from the first time point to the second time point; and calculating, using a control circuit of the mobile communication device, a maximum number of attempts to be performed respectively for each of a plurality of procedures for restoring the wireless link to the LTE network, wherein the maximum number of attempts performed for each of the plurality of procedures is based on the amount time elapsed from the first time point to the second time point, wherein a first one of the plurality of procedures comprises the transceiver transmitting scheduling request (SR) messages, wherein a second one of the plurality of procedures comprises the transceiver transmitting (SR) messages over a random access channel (RACH), and wherein a third one of the plurality of procedures comprises the transceiver transmitting radio resource control (RRC) re-establishment requests wherein the determined maximum numbers of attempts include a first maximum number of attempts, a second maximum number of attempts, and a third maximum number of attempts; performing, at the mobile communication device, the plurality of procedures according to the determined maximum numbers of attempts, wherein the performing the plurality of procedures includes:
