- the configuration of the RNC is the same as that of FIG. 11, and the configuration of Node B is the same as that of FIG.
- MCCH data # 1510 repeatedly transmitted in change period # 1505 and # 1506, and MCCH data # 1511 repeatedly transmitted in change period # 1507 are transmitted from Node B200 to UE300. It indicates the timing of MCCH data transmission at the time of transmission.
- the MICH data # 1501 and # 1503 are also transmitted to Node B 200 with RNC900 power. Further, MCCH data (not shown) is transmitted from the RNC 900 to the Node B 200. Node B 200 that has received MICH data # 1501 transmits MICH data # 1501 to UE 300 at the beginning of change period # 1505. Further, Node B 200 receiving MICH data # 1503 transmits MICH data # 1503 to UE 300 at the beginning of change period # 1506. In addition, MCCH data # 1510 is repeatedly transmitted to UE 300 in the cycle of repetition period # 1508 in Node # and change period # 1505 and # 1506, and differs from MCCH data # 1510 in change period # 1507. With data A certain MCCH data # 1511 is repeatedly transmitted to UE 300 in a cycle of repetition period # 1509.
- MICH the same change period # 1505 and change period # 1506 are set, and change period # 1507 having a different length from change period # 1505 and change period # 1506 is set. Then, the RNC 900 notifies the Node B 200 and the UE 300 of the timing # 1512 at which the change period # 1506 changes to the change period # 1507 using the operation time information. Also, the length of the repetition period # 1508 and the repetition period # 1509 are different.

- CFN comparing section 1902 compares the CFN set in the MICH data received from RNC 1600 with the CFN information input from CFN storage section 1901, and outputs the information of the comparison result together with MICH data to selection section 1903. Output to Also, when receiving the MCCH data and the MTCH data from the RNC 1600, the CFN comparing unit 1902 performs the CFN comparison. Output to selection section 1903 without performing.
- selecting section 1903 determines that the MICH data input from CFN comparing section 1902 is the PHY section if the CFN does not match. If the information is output to the 1702 and the CFN is the information of the comparison result that matches, the MICH data input from the CFN comparing unit 1902 is discarded without being output to the PHY unit 1702. When MCCH data and MTCH data are input from CFN comparing section 1902, selecting section 1903 outputs the data to PHY section 1702 as it is.
