Abstract: A method of MDT measurement configuration triggering for a mobile device in a wireless communication system is disclosed. The method comprises determining whether an event predefined in the mobile device occurs, and transmitting a message for indicating a network of the wireless communication system to configure a MDT measurement to the mobile device, to the network when the event occurs.

Abstract: A user equipment is configured to operate in an idle mode according to an MDT configuration. When receiving an activation signal from a base station, the user equipment is configured to execute one or multiple logged MDTs in the idle mode according to the activation signal and the MDT configuration.

Abstract: A user equipment is configured to operate in an idle mode according to an MDT configuration. When receiving a modify/setup signal from a base station, the user equipment is configured to update the MDT configuration accordingly in the idle mode and perform one or multiple corresponding logged MDTs according to the updated MDT configuration.

Abstract: A method of cell reselection for a mobile communication system comprises determining whether a mobile device in the mobile communication system is capable of initiating an emergency call through the second cell when a network of the mobile communication system restricts the mobile device from accessing a first cell, and the mobile device performs a first cell reselection procedure to switch the first cell to the second cell, so as to generate a first determination result, and determining whether the mobile device camps on the second cell according to the first determination result.

Abstract: A wireless communication system includes a user equipment and multiple types of networks. The user equipment stores the cell information of a current cell in a database when the user equipment is camping on the current cell or after the user equipment performs cell reselection to a new cell. The user equipment determines whether inter-RAT cell reselection should be performed according to the system information received from the current cell and the cell information of previous cells stored in its database. Even if the current cell fails to broadcast the accurate and updated information of all neighboring cells, the UE may further check the database periodically or randomly for its previous camping history. Therefore, inter-RAT cell reselection may be properly performed between networks using different RATs in order to reduce call drop rate and improve user experience.

Abstract: A communication system includes a user equipment and a network having a first cellular station and a second cellular station. When an attempt to establish an RRC connection between the first cellular station and the user equipment fails, the user equipment is configured to perform another RRC connection establishment procedure on the second cellular station. Therefore, when certain cellular stations within the network are busy, the present invention can improve the success rate of location registration procedures by requesting RRC connection with other available and less busy cellular stations within the network.

Abstract: According to one or multiple transmission parameters, one or multiple measurement targets are set for a plurality of data links provided by a user equipment in UMTS. The data throughput of each measurement target during a specific period is summed up for acquiring an uplink scheduled IP throughput and a downlink scheduled IP throughput of each measurement target.

Abstract: A method of handling cell selection for a mobile device in a wireless communication system is disclosed. The mobile device is transferring from a first mode to a second mode. The method comprises determining whether a plurality of active sets of the mobile device comprises at least one first cell of a location area of the wireless communication system, for producing a result, and the location area comprising a first cell serving the mobile device when the mobile device transfers from the second mode to the first mode; and selecting a second cell from the at least one first cell for camping in the second mode, when the result indicates that the plurality of active sets comprise the at least one first cell.

Abstract: In a universal mobile telecommunications system, a radio access network includes multiple base stations for communicating with user equipment. The radio access network is configured to send the user equipment a measurement control message which includes configuration information and a location reporting indicator. The user equipment is configured to perform a minimization of drive test according to the configuration information, and provide location information along with the recorded measurement result according to the location reporting indicator.

Abstract: The present disclosure proposes a network diversity based error reporting method and a user equipment using the same method. The user equipment using the proposed method in the event of a network error would establish a first connection with a first network, establish a second connection with a second network which is a different type of network from the first network, establish a first failure report corresponding to the first connection in response to failing to connect with the first network, transmit through the second connection the first failure report to the second network in response to establishing the first failure report, establish a second failure report corresponding to the second connection in response to failing to connect with the second network, and transmit through the first connection the second failure report to the first network in response to establishing the second failure report.
