Abstract
A mobile communications device with a wireless module and a controller module is provided. The wireless module performs wireless transmissions and receptions to and from a first service network being an LTE system. The controller module receives, from the first service network, a handover request message for handing over from the first service network to a second service network via the wireless module, and determines whether all configurations in the handover request message are compliable or whether there is a protocol error in the handover request message. Particularly, the second service network utilizes a wireless technology other than the LTE technology, and the handover request message is a MobilityFromEUTRACommand message. Also, the controller module transmits a connection re-establishment request message indicating a reconfiguration failure to the first service network via the wireless module, in response to one of the determinations is positive.
