A mobile device with a port map maintaining a list of open ports for incoming data packets is provided. A first processor receives and demodulates inbound signals into data packets. A second processor processes at least one application bound to at least one open port. The second processor enters a sleep mode to reduce power consumption if no data packet is sent from the first processor to the second processor. When the first processor receives an inbound request signal, the first processor demodulates the inbound request signal into a first data packet targeted to a destination port, and looks up the port map to determine whether the destination port is listed in the port map. If the destination port is not listed in the port map, the first processor transmits a response signal to the sender of the inbound request signal or omits the inbound request signal without waking up the second processor.

Mobile device and data connection method thereof

A user equipment (UE) implementing a message recovery method is disclosed, supporting messages of both the circuit switched (CS) domain and the packet switched (PS) domain. The UE roams in a wireless telecommunications system and performs a call setup procedure. When the UE receives an NAS message comprising a domain identifier and a protocol discriminator, the UE determines whether the domain identifier and the protocol discriminator are of the same domain. If the domain identifier and the protocol discriminator are of the same domain, the UE proceeds with processes corresponding to the NAS message. If the domain identifier and the protocol discriminator are of different domains, the NAS message is determined to be an error message, and the UE modifies the domain identifier of the NAS message to generate a recovered NAS message, and determines whether the recovered NAS message is compatible to the call setup procedure.
