A mobile communication device including a Radio Frequency (RF) device and a baseband processor is provided. The RF device performs wireless transmission and reception to and from one or more cells. The baseband processor uses a first subscriber identity to establish a connection with a serving cell via the RF device to perform a first communication procedure, and in response to completing the first communication procedure or the first communication procedure being interrupted by a second communication procedure associated with a second subscriber identity, uses the first subscriber identity to send a measurement report to the serving cell via the RF device. In particular, the measurement report indicates a reported signal quality of the serving cell is poor enough to release the connection.

A method and a system for data traffic offload are provided. The method includes the following steps. Create a local tunnel between a first base station and a second base station according to a first record and/or a second record. The first base station and the second base station are located on a front-end network. The first record corresponds to a first user equipment and the first base station. The second record corresponds to a second user equipment and the second base station. Route network packets transmitted between the first user equipment and the second user equipment via the local tunnel.

A selection method for transmitting network packets adapted to be executed by a multiple-interface network device is provided. The multiple-interface network device includes a plurality of network interfaces. Each of the network interfaces connects to one of multiple communication networks. The selection method includes the following steps: collecting a transmission status of each of the communication networks; analyzing transmission characteristics of a predetermined number of packets of a service flow to determine a traffic pattern type of the service flow; comparing the transmission status of each of the communication networks with the transmission requirements of the traffic pattern type of the service flow to select one of the network interfaces, and using the selected network interface to transmit packets of the service flow. The service flow is constituted by packets transmitted by the network interfaces through a port and packets received by the network interfaces through the same port.

An authentication method for user equipment (UE) and LIPA network entities is applicable to a cross-LIPA communication environment having an UE end, a visiting LIPA network entity end (LIPA), and a home LIPA network entity end (LIPA). The UE end successfully registers to a core network (CN) via the LIPA, thereby attaining mutual trust relationship between the UE end and the LIPA. The UE end successfully registers to the CN via the LIPA, thereby attaining mutual trust relationship between the UE end and the LIPA. The LIPArequests the UE end via the LIPAfor successfully re-authenticating the CN, thereby attaining mutual trust relationship between the LIPAand the LIPA.
