1. A method in a wireless communication device, comprising:

  • providing a wireless communication device including;

    a controller configured to control the operations of the wireless communication device;

    a transceiver coupled to the controller;

    a discovery attempt timer configured to start a timing procedure in response to a first discovery request;

    an unlicensed wireless local area network mobile access radio resource module coupled to the controller and the discovery attempt timer, the unlicensed wireless local area network mobile access radio resource module configured to initiate the first discovery request, detect a failure in a connection to an unlicensed network controller in response to an expiration of the discover attempt timer, and release a wireless local area network access point connection to the unlicensed network controller prior to initiating a second discovery request; and

    a discovery procedure restart timer coupled to the controller and the unlicensed wireless local area network mobile access radio resource module, wherein the unlicensed wireless local area network mobile access radio resource module starts the discovery procedure restart timer in response to detecting the failure;

    operating the wireless communication device on a wireless local area network by being coupled to the unlicensed wireless local area network mobile access radio resource module; and

    configuring the wireless communication device with a mobility management module coupled to the controller, the mobility management module configured to attempt access to wireless wide area network services in response to receiving a signal from the unlicensed wireless local area network mobile access radio resource module indicating the failure in the connection to the unlicensed network controller.
