Disclosed are a base station device and a call connection method for reducing a call connection delay. According to the device and method; in ST, a terminal acquires an identifier managed in a base station; in ST, radio resource information required for a service desired by the terminal is decided; in ST, by using the identifier acquired in ST, the terminal transmits a request for establishing RRC connection to the base station. In ST, according to the radio resource information received from the terminal, the base station decides the radio resource to be set for the terminal before authentication by an upper layer node, and the base station extracts information destined to the upper layer node. In ST, the information destined to the upper layer node is transmitted to the upper layer node. In ST, the setting contents of the radio resource decided in STare transmitted to the terminal.

Integrated circuit for radio communication mobile station device and call connection method

A mobile wireless system includes a first gateway (L-PGW), a second gateway (PGW), a first access point (HeNB) capable of establishing a communication path simultaneously with the first and second gateways, and a second access point (eNB) capable of establishing a communication path only with the PGW. When a mobile terminal connected to the HeNB and communicating with a communication destination node using a first path through the L-PGW switches a connection destination to the eNB, the HeNB establishes a second path through the HeNB and the PGW, while maintaining the first path. The HeNB transmits data, which has been transmitted to the HeNB along the first path, to the eNB along the second path, until the UE is connected to the eNB, and a third path to the communication destination node through the PGW is established. Accordingly, an interruption time of data reception involved in handover is shortened.

A mobile communication system wherein the upstream radio channel interference of a macrocell connection terminal with a femtocell base station can be reduced while the consumption of radio resources caused by increase in signaling is being suppressed. The macrocell connection terminal () performs, based on an instruction from a macrocell base station (), an upstream channel transmission and further reports a peripheral-femtocell detection result obtained by a measuring unit to the macrocell base station. The macrocell base station () instructs the terminal to perform a peripheral-femtocell detection. The identifier of the terminal and the peripheral-femtocell detection result obtained by the terminal are transmitted to a network management apparatus (). An interference reduction instruction (frequency band allocation) and the identifier of the terminal to be interference-controlled are received from the network management apparatus, and the frequency band allocation in the upstream channel transmission of the terminal to be interference-controlled is so controlled as to satisfy the interference reduction instruction.

It is possible to provide a radio communication terminal device, a radio communication base station device, and a radio communication method capable of rapidly completing a handover even during DRX/DTX. In the devices and the method, a terminal () transmits a quality measurement result to a base station () at an Active interval. Here, the terminal () sets the DRX/DTX interval to a short interval since performance of a handover is predicted. The base station () which has received the quality measurement result transmitted from the terminal () recognizes that the terminal has set the DRX/DTX interval to a short interval and transmits a handover instruction to the terminal () at the Active interval, considering the shortened DRX/DTX interval.

The invention relates to a method for distributing control signaling for session control of a multicast or broadcast service within a mobile communication network. Furthermore the invention also provides a base station, mobile terminal and communication system to perform the proposed method. In order to reduce the number of signaling connections for the service, the invention proposes to avoid the initial distribution of session control signaling in the entire mobile communications network or service area. Rather than providing service related control signaling connections upon session start, the control signaling connections are set up in response to service requests of the mobile terminals requesting the service. According to one further aspect, the mobile terminals send the service requests based on service announcements available at the mobile terminals, i.e. in contrast to conventional implementations, the mobile terminals do not await a notification of the access network on the availability of the service within the cell.

Disclosed are a radio communication base station device and a radio communication method which can reduce the interruption time of a service being received by UE while suppressing a resource consumption amount in an SFN area when the UE performs a handover from the SFN area to a non-SNF area. An MBMS reception request identification unit () judges an RRC message inputted from the UE (). If an MBMS reception request is contained, an MBMS reception request is transmitted to an MBMS reception request storage unit (). Moreover, when the RRC message from the UE () contains an adjacent cell reception quality measurement result, a handover decision unit () judges whether to perform a handover to the adjacent cell. The MBMS reception request storage unit () stores the MBMS reception request outputted from the MBMS reception request identification unit (). When the handover decision unit () which has decided the handover requests for transmission of an MBMS reception request, the MBMS reception request storage unit () transmits the MBMS reception request to an MME ().
