摘要： A communication terminal is capable of simultaneously communicating through a plurality of carriers by carrier aggregation, and the communication terminal comprises: a quality measurement unit for measuring the reception quality of a radio wave transmitted through a plurality of carriers from a base station of a connected cell to obtain a measured value; a primary carrier storage unit storing information specifying a primary carrier chosen from the plurality of carriers; a comparator for comparing a measured value of the primary carrier measured by the quality measurement unit to a threshold value; and a cell search unit for searching for another cell when the measured value of the primary carrier is less than or equal to the threshold value. Consequently, a search threshold value for carrier aggregation can be appropriately determined to perform a cell search and a quality measurement.

摘要： Methods for detaching a mobile terminal from a mobile communication network. Furthermore, the invention also relates to a mobile terminal and a mobility management entity that perform these methods. The invention is inter alia applicable to a 3GPP LTE-A system following the Evolved Packet System (EPS) architecture. The invention proposes that the detach procedure of a mobile terminal is triggered by the mobile terminal being transferred into idle state. The mobility management entity can trigger the detach procedure in response to this event. The detach procedure may be deferred by a given time span. A detach timer may be configured in the mobile terminal and the mobility entity for this purpose, and upon expiry of the detach timer in the mobile terminal and the mobility management entity, both silently delete the context information related to the mobile terminal's user plane and control plane to detach the mobile terminal.

摘要： The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

摘要： Provided are a base station, a terminal, a band allocation method, and a downlink data communication method in which a mapping method for synchronization signals and report signals is implemented with high resource usage efficiency when a first system in which an independent single communication is allocated to a unit band co-exists with a second system in which a plurality of unit bands can be allocated to a single communication. In a base station (200), an OFDM signal generation unit (225) maps primary synchronization channel (P-SCH), secondary synchronization channel (S-SCH), primary broadcast channel (P-BCH), and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands available to the station itself. The OFDM signal generation unit (225) also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all of the plurality of unit bands to produce a multiplexed transmission signal. When the terminal which has transmitted terminal capability information is an LTE+ terminal, a control unit (265) transmits a band movement indication which indicates changes in the reception band to that terminal.

摘要： A technique is disclosed to realize the change of session seamlessly and with high degree of freedom while reducing the increase of the processing load on a session control server upon a request to change the session from a terminal and to decrease the load on network traffic. According to this technique, trigger information is embedded in a session of content used by the terminal. When this trigger information is detected, the terminal carries out an operation to set up as trigger action (e.g. the change to another session). The relation between the trigger information and the trigger action may be described in sequence information, which is held by the terminal in advance or the trigger action may be described in the trigger information. With regard to certain trigger information, different types of trigger actions may be set up for each terminal (or, depending on the condition of the terminal). As a result, different types of session change can be performed, depending on each terminal and on the conditions of the terminals.

摘要： Disclosed is a technique for starting an application used to receive a message for the application efficiently in order to reduce the processing load on and the battery consumption of a user terminal. According to this technique, a network is requested to transmit a control message to a user terminal when receiving a message addressed to an application on the user terminal, and when receiving, from a server, a message addressed to the application on the user terminal, the network transmits a control message such as paging to the user terminal. The user terminal receives the paging from the network even in the connected mode, and starts an application used to receive a message for the application on the user terminal in response to the reception of the paging so that the application can be started at timing where there exists the message to be received.

摘要： Provided are a radio terminal device, a radio base station device, and a channel signal forming method which can prevent quality degradation of the downlink source allocation information by reducing the frequency of the zero information addition process to the downlink resource allocation information when executing communication using an uplink unit band and a plurality of downlink unit bands correlated to the uplink unit band. A base station (100) can execute communication using the uplink unit band and a plurality of downlink unit bands correlated to the uplink unit band. The base station (100) includes: a PDCCH generation unit (102) which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit (103) which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size.

摘要： The invention relates to methods for scheduling of uplink transmission and generating transport blocks according to multiple received uplink assignments Furthermore, the invention is also related to the implementation of these methods in hardware and software. To propose strategies for generating plural transport blocks within a given time constraint, the invention introduces prioritization of the uplink assignments, so that multiple uplink assignments can be ranked in the mobile terminal in a priority order. The prioritization of the uplink assignments is used to determine the order in which the individual transport blocks corresponding to the uplink assignments are filled, respectively how the data of different logical channels is multiplexed to the transport blocks for transmission in the uplink. Another aspect of the invention is to suggest joint logical channel procedures that operate on virtual transport blocks accumulated from the received uplink assignments. One or more such joint logical channel procedure can be performed in parallel.
