Abstract: Since OFDM (Orthogonal Frequency Division Multiplexing), which is a downlink access scheme used for an LTE (Long Term Evolution) communication system, is weak at interference, it is preferable that the number of base stations for transmitting the same E-MBMS (Evolved Multimedia Broadcast Multicast Service) data base not excessive. Thus, the mobile terminal performs: processing of obtaining measurement quality values by measuring reception quality of each base station; processing of deciding on whether the measurement quality value of a serving base station exceeds a certain receiving level; processing of adding measurement quality values of other base stations to the measurement quality value of the serving base station until the sum exceeds the certain receiving level; and processing of notifying the serving base station of the serving base station and other base stations as candidates for an active set for E-MBMS.

Abstract: An accessory, an electronic apparatus and a system for accessory certification is disclosed. The accessory comprises an encryption chip, with the encryption chip comprising a first memory module, configured to store a private certification key and a mixed certification key formed at least by combining a public certification key and pseudo keys according to a predetermined rule. The processing module of the electronic apparatus at least extracts the public certification key from the mixed certification key according to an algorithm matched with the predetermined rule when the electronic apparatus and the accessory are forming a physical connection. The processing module uses the public certification key to certify the accessory. In such a manner, the present invention can improve the security level of keys so as to improve the security and reliability for the electronic apparatus to use the accessory.

Abstract: A mobile terminal monitors a candidate set (Candidate Set) of L1/L2 control information. However, when a base station carries out signaling of a candidate set to each of all mobile terminals, the load on the base station from the viewpoint of radio resources becomes large. Furthermore, the amount of processing in performing a blind detection of each mobile terminal also increases. Therefore, the base station carries out a process of performing grouping of the above-mentioned mobile terminal which is a destination of transmission of the above-mentioned L1/L2 control signal, a process of allocating an L1/L2 control signal to be transmitted to a predetermined mobile terminal to the control channel elements included in a group to which the predetermined mobile terminal is belonging on the basis of attribution information about the mobile terminal.

Abstract: A communication system has three types of cells including, in addition to an MBMS dedicated cell, a unicast cell to and from which a mobile terminal can transmit and receive individual communication data, and a unicast/MBMS-mixed cell which can provide both a service provided by the unicast cell and a service provided by the MBMS dedicated cell. While receiving the broadcast type data transmitted from the MBMS dedicated cell, the mobile terminal makes a notification of an MBMS receiving state via the unicast cell or the unicast/MBMS-mixed cell to transmit information for identifying the MBMS dedicated cell, and the communication system transmits a paging signal to the mobile terminal currently receiving the broadcast type data transmitted from the MBMS dedicated cell on the basis of a tracking area (Tracking Area) in which the mobile terminal is tracked, the tracking area being determined on the basis of the information transmitted.

Abstract: The present invention provides a method for coupling the mobile terminal with the adapter. Firstly, coupling the mobile terminal with the adapter by RF induction; secondly, decreasing transmitted power of the mobile terminal so that the RF power leaking around is maintained below a specified value when the mobile terminal detects that it has been coupled with the adapter; finally, controlling the gain controlling means of the adapter by the mobile terminal to compensate the power loss due to the RF coupling and the transmitting power decreased by the mobile terminal itself, so that the transmitted power from the antenna of the adapter can reach the due power level transmitted by the mobile before it is coupled with the adapter. The structure of the mobile terminal is simplified and the price of the mobile terminal is decreased because the mobile terminal is coupled with the adapter through RF induction, and the RF changeover switch is not provided in the mobile terminal any more.
