摘要： An Al film is formed on a barrier metal covering a thin film resistor to have a first opening. A photo-resist is formed on the Al film and in the opening, and is patterned to have a second opening having an opening area smaller than that of the first opening and open in the first opening to expose the barrier metal therefrom. Then, the barrier metal is etched through the second opening. Because the barrier metal is etched from an inner portion more than the opening end of the first opening, under-cut of the barrier metal is prevented.

摘要： 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 (401) performs, based on an instruction from a macrocell base station (402), 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 (402) 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 (404). 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.

摘要： 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.

摘要： 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 (127) judges an RRC message inputted from the UE (100). If an MBMS reception request is contained, an MBMS reception request is transmitted to an MBMS reception request storage unit (124). Moreover, when the RRC message from the UE (100) contains an adjacent cell reception quality measurement result, a handover decision unit (126) judges whether to perform a handover to the adjacent cell. The MBMS reception request storage unit (124) stores the MBMS reception request outputted from the MBMS reception request identification unit (127). When the handover decision unit (126) which has decided the handover requests for transmission of an MBMS reception request, the MBMS reception request storage unit (124) transmits the MBMS reception request to an MME (140).

摘要： A radio communication terminal, a radio communication base station device, and radio communication method enabling lightening the paging load in a mobile communication system including macro cells and femto cells. A reception level measuring section (144) of a UE (104) measures the reception level of a femto cell. If a judging section (146) judges that the measured reception level is over a level which is the sum of a threshold and an offset value, the judging section (146) requests an MME (101) to change a multi TA registration to a single TA registration and carries out a change to one tracking area registration.

摘要： A control station apparatus ensures that, even if transmission times are changed and set, data of channels can be acquired at the receiving end. In this apparatus, a synchronization part (102) uses an RFN counter value and a BFN counter value to synchronize an RNC with a Node (B). An NBAP part (104) sets a changed interval variable and decides, from information of an SFN counter value and a CFN counter value with which the RFN counter value is synchronized, a timing at which to change the changed interval, and transmits, as operation time information, the decided timing to the Node (B). An FP part (107) repetitively transmits the same MCCH data to the Node (B) in a predetermined period for each of changed intervals, while transmitting MICH data to the Node (B) at a predetermined timing.

摘要： The invention relates to a method for providing measurements on a bit-rate provided to scheduled data having a guaranteed bit-rate and being transmitted on at least one dedicated uplink data channel by at least user equipment via a C-RNC. Further, the invention also relates to a method for initiating congestion control for scheduled data of at least one guaranteed bit-rate priority class in a mobile communication system. Moreover, the invention relates to a C-RNC as well as a serving radio network controller performing these methods. To enable the C-RNC within a mobile communication system to perform congestion control for uplink transmissions having a guaranteed bit-rate the invention suggests to provide the C-RNC with a bit-rate being provided to scheduled data of the guaranteed bit-rate priority class using common or dedicated measurement procedures. This provided bit-rate is evaluated and taken as a basis for deciding on whether congestion control for data of the priority class needs to be performed.

摘要： A cell receiver includes, in addition to a cell decomposing unit, an interleaving memory, an error correcting unit, a FIFO memory, and a delay fluctuation absorption control unit, a delay fluctuation absorption buffer for absorbing delay fluctuation of a received cell, and a buffer control unit for controlling a read operation of a cell from the delay fluctuation absorption buffer. Since the delay fluctuation of a received cell is absorbed by the delay fluctuation absorption buffer, the number of memories necessary for interleaving can by reduced to two memories.
