Abstract
A method for performing handover by wireless User Equipment (UE) is provided. The UE includes a Long Term Evolution-Mobile Extreme Convergence (LTE-MXC) application processor, a LTE processor and a Digital Signal Processor (DSP). The UE buffers a set of IP packets when a Radio Access Technology (RAT) indicator is less than a pre-defined threshold and sends the set of IP packets to the LTE processor and the DSP. The LTE processor transmits the set of IP packets to the LTE network and sends acknowledgement signals to the LTE-MXC application processor and the DSP. When the handover is complete, the LTE processor sends the transmission status of the set of IP packets to the DSP. The UE also includes multimode Radio Resource Control (RRC) and Non-Access Stratum (NAS) modules.
