By adding a public identifier for designating a PAN configured by a communication terminal owned by a user to subscriber information managed in a mobile communication network, it is possible to manage a plurality of communication terminals as a group. The mobile communication network 2 includes a communication control device 4 for managing subscriber information and performing communication control. A communication terminal #1 on which USIM 8 is mounted is connected to communication terminals #2 and #3 constituting PAN 7 together with the communication terminal #1. The communication control device 4 manages a public identifier for designating the communication terminal #1 for performing a call connection or a session connection to the communication terminal #1 and at least one public identifier for identifying the PAN 7 formed by the communication terminals #1, #2, and #3 while correlating them with the communication terminal #1 and to the public identifier for identifying the PAN 7, thereby managing profile information including configuration of the PAN 7 and the service attribute which can be used by the PAN 7.

A session control method for a mobile communication system including a session control device for executing the control of sessions according to instructions from an application server, includes managing a group of plurality of communication terminals owned by same user and types of sessions processable by each of the communication terminals constituting the group. When a session establishment request is executed to any one of the plurality of communication terminals constituting the group, any one from the plurality of communication terminals comprising the group may be selected depending on type of session requested to be established, and the session connection to the selected communication terminal is executed. The constitution of the communication terminals of the group can be changed according to request from the communication terminals. The types of sessions processable by each of the communication terminals constituting the group can be changed according to request from the communication terminals.

Methods, systems, and devices provide improved proximity services. In one aspect, a base station includes an information generating module and an information transmission module. The information generating module generates control information for causing a mobile device to initiate a discovery signal transmission procedure. The discovery signal transmission procedure allows the mobile device to be discovered. The information transmission module transmits the control information to the mobile device. In another aspect, a mobile device includes an information receiving module, a control module, and a signal transmission module. The information receiving module receives control information. The control module initiates a discovery signal transmission procedure for proximity services responsive to the information receiving module receiving the control information. The discovery signal transmission procedure includes generating a discovery signal allowing the mobile device to be discovered. The signal transmission module broadcasts the discovery signal.

A random access instructed by a base station apparatus and having a small delay is enabled in Advanced-EUTRA system. Upon detection of control data in any one of a plurality of component carriers, component carrier information, a preamble number, and random access channel information are extracted from the control data, and if the extracted information indicates dedicated preamble transmission, a random access channel position to be used is selected from information on random access of a component carrier specified in the component carrier information and the random access channel information, a random access preamble is generated from the information on random access and the dedicated preamble number, and the random access preamble is transmitted at the random access channel position.
摘要:
Disclosed are a communication system, a base station apparatus, a mobile station apparatus, and a method for communication, which facilitate efficient administration of information for settings maintained by base station apparatuses and mobile station apparatuses in a system involving a plurality of component carriers. A mobile communications system including the base station apparatus and the mobile station apparatus administers the system information of one or more component carriers possessing select spectrum width from the system spectrum. When a component carrier is added to the mobile station apparatus, the system applies the system information belonging to the component carriers already connected to the system to the component carrier added thereto.
摘要:
A mobile communication system in which a mobile station apparatus transmits reception quality information to a base station apparatus, the reception quality information indicating quality of a signal received from the base station apparatus, characterized in that the base station apparatus transmits information for instructing transmission of reception quality information without uplink data included in an uplink data transmission permission signal, and the mobile station apparatus transmits reception quality information without the uplink data according to the information for instructing transmission of reception quality information without uplink data. This allows a mobile station apparatus to transmit reception quality info information including a large amount of information even if there is no uplink data between the mobile station apparatus and the base station apparatus, and the transmission control flexibly responding to the amount of information and the frequency of transmissions of the reception quality information transmitted from the mobile station apparatus is possible.

Methods, systems, and devices provide improved power control for signals used for device-to-device services. In one aspect, a user equipment (“UE”) terminal controls the transmission power of signals used for device-to-device (“D2D”) services based on power control parameters provided by a base station. The UE terminal includes a first power control module for controlling a first transmission power to be applied to signals used for communication with a base station. The UE terminal also includes a second power control module for controlling a second transmission power to be applied to signals used for D2D services. The first and second transmission powers can be determined based on at least one power control parameter received from the base station. The UE terminal also includes a signal transceiver module for transmitting signals used for uplink/downlink communications using the first transmission power and transmitting signals used for D2D services using the second transmission power.
