A network accessing method includes performing a cell search procedure for a first RAT; receiving first SI from a first cell of the first RAT when the first cell has been found in the cell search procedure; determining whether second SI is scheduled by the first cell according to content of the first SI; receiving the second SI in response to determination of the second SI being scheduled and deriving information regarding a second cell of a second RAT different from the first RAT; searching for the second cell according to the information regarding the second cell; and attempting to access the second cell instead of the first cell when the second cell has been found. The first cell is configured to provide access to a first core network and the second cell is configured to provide access to a second core network different from the first core network.

Network accessing method and communications apparatus utilizing the same

An interface system for functional module and a functional module thereof are provided. The interface system for the functional module includes a main system and a plurality of functional modules. The main system has a mother board. Each of the functional modules has a circuit board, and at least one functional element disposed on the circuit board, and the functional element is an element having various functions and specifications. An expansion assembly is disposed between the mother board of the main system and the circuit board of any of the functional modules, and the expansion assembly is also disposed between the circuit boards of the functional modules. The main system is selectively and electrically connected to the functional modules through each of the expansion assemblies to be connected extendedly.

Interface system for functional module and functional module thereof

A battery management system for a main system of an electronic device is provided. The battery management system is electrically connected with plural battery units. The battery management system includes plural insertion slots and a battery detachment protection device. The insertion slots electrically connected with the main system. The plural battery units are docked with the corresponding insertion slots. The battery detachment protection device is electrically connected with the main system. When an external force is applied to the battery detachment protection device, the battery detachment protection device generates a system protection sensing signal. In response to the system protection sensing signal, a power supply condition of at least one battery unit in the corresponding insertion slot is adjusted, and the at least one battery unit in the corresponding insertion slot is permitted to be detached from the corresponding insertion slot or positioned in the corresponding insertion slot.

Battery management system

Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established.

Maintaining a packet-switched signaling connection during handover between cells

A method of applying a network forbidden list for enhanced service recovery in mobile communication networks is provided. In a first embodiment, upon receiving an error cause for a RAT in a selected network, a UE stores a PLMN ID, the RAT information, and the error cause as an entry in the forbidden list. The UE will not select to the RAT of the network stored in the forbidden list until the PLMN/RAT entry is removed from the forbidden list. In a second embodiment, upon receiving an error cause in a selected network, a UE stores a PLMN ID, the error cause, and a timer value as an entry in the forbidden list. The UE will not select to the network stored in the forbidden list until the timer associated with the PLMN ID is expired.
