A communication device for communicating with a long-term evolution (LTE) network and a new radio (NR) network comprises at least one storage device; and at least one processing circuit coupled to the at least one storage device. The at least one storage device stores, and the at least one processing circuit is configured to execute instructions of: the communication device registering to the LTE network and the NR network; and performing an IP multimedia subsystem (IMS) registration via the LTE network but not via the NR network, when registering to the LTE network and the NR network.

Method and device of communicating with a LTE network and a NR network

A power saving method for a mobile device in a wireless communication system is disclosed. The power saving method comprises obtaining a first parameter according to a first signal transmitted between the mobile device and a first network; estimating a first power consumption of the mobile device in the first network according to the first parameter and a first radio access technology (RAT) employed in the first network; determining whether the first network is suitable according to at least a comparison of the first power consumption with a second power consumption of the mobile device in a second network, wherein the second network employs a second RAT different from the first RAT; and switching to a the second network when the first network is not suitable.

Power saving method and related communication device

A method for radio access technology, hereafter called RAT, change for a mobile device is disclosed. The method comprises whenever camping on a RAT, collecting cell information for at least one cell, falling back to a first RAT, and performing an offline procedure for moving to the camped RAT from the first RAT according to the collected cell information.
