The wireless information is notified to the dedicated channel control information generation unit 112 as a wireless information signal S3.

[0043] Dedicated channel control information generating section 112 is a wireless layer that is used by HHO destination base station apparatus 120B of mobile station apparatus 130 and is physical layer information passed from radio information extracting section 117! Information signal S3 is passed to base station apparatus 120A as DCCH information signal S5 of dedicated channel control information generation section 112.

[0044] Then, before the mobile station device 130 HHOs the mobile station device 130 from the cell 121A of the base station device 120A to the cell 121B of the base station device 120B, the dedicated channel control information generation unit 112 uses the base station device 120B of the HHO destination. Informs the HHO base station apparatus 120A of the physical layer information used! The information of the physical layer used in the HHO destination base station apparatus 120B is also notified to the mobile station apparatus 130 of the HHO source base station apparatus 120A.

[0045] Also, the dedicated channel control information generation unit 112 sends an instruction signal S6 instructing the mobile station device 130 to HHO to the base station device 120A. In addition, the mobile station apparatus 130 sends an HHO signal S 7 that tells the mobile station apparatus 130 to HHO to the identification unit 115.

When mobile station information management section 114 receives registration information inquiry signal S9 related to MBMS of mobile station apparatus 130 to be HHOed from identification section 115, mobile station information management section 114 performs the requested movement. The registration information about the MBMS of the station apparatus 130 is passed as the registration information signal S 10 to the identification unit 115.

[0049] When receiving the HHO signal S7 that tells the mobile station device 130 to perform HHO from the dedicated channel control information generating unit 112, the identification unit 115 determines whether the mobile station device 130 is registered to receive MBMS. In order to identify this, an inquiry signal S9 is sent to the mobile station information management unit 114.

[0050] As a result, the identification unit 115 receives from the mobile station information management unit 114 the registration information signal S10 related to the MBMS of the mobile station apparatus 130 inquired by the inquiry signal S9.

[0051] Then, the identification unit 115 identifies whether or not the mobile station apparatus 130 to be HHO is a terminal that is registered for MBMS reception based on the received registration information signal S10, and the mobile station apparatus 130 Is an MBMS reception registered terminal, the identification signal S11 is sent to the MBMS reception confirmation unit 116.

[0052] When the MBMS reception confirmation unit 116 confirms that the mobile station device 130 to be HHO is an MBMS reception registered terminal based on the identification signal S11 received from the identification unit 115, the MBMS control Based on the MCCH information of the MBMS control information signal S8 received from the information generation unit 113, the mobile station device 130B transmits the MBMS received by the mobile station device 130 in the HHO destination base station device 120B, and determines whether or not the power is .

[0053] Then, the MBMS reception confirmation unit 116 transmits the MBMS received by the mobile station device 130 that is performing the HHO and is received by the mobile station device 130 to the base station device 120B that is the HHO destination. If it can be determined, MBMS reception confirmation signal S 12 is sent to radio information extraction section 117.

[0054] As described above, radio control apparatus 100 requires that individual channel control information generation section 112 perform HHO of mobile station apparatus 130 from cell 121A of base station apparatus 120A to cell 121B of base station apparatus 120B. Information is generated, and this is notified from the base station apparatus 120A to the mobile station apparatus 130 as an information signal S5 before the HHO of the mobile station apparatus 130.

[0055] Also, the dedicated channel control information generation unit 112 notifies the identification unit 115 that there is an HHO target mobile station device 130 using the HHO signal S7.

[0056] Upon receiving the notification, the identification unit 115 confirms that the HHO target mobile station apparatus 130 is registered to receive MBMS. The mobile station information management unit 114 is inquired by the inquiry signal S9 whether or not the communication is performed.

[0057] Upon receiving the inquiry, mobile station information management section 114 passes a list of MBMS received and registered by mobile station apparatus 130 to identification section 115 as registration information signal S10.

[0058] The identification unit 115 identifies the mobile station device 130 when there is at least one MBMS that the mobile station device 130 is receiving and registering in the list of MBMSs passed from the mobile station information management unit 114. An identifier for identifying the MBMS and an identifier for identifying the MBMS are notified to the MBMS reception confirmation unit 116 by the identification signal S11.

[0059] The MBMS reception confirmation unit 116 transmits the MBMS of the notified identifier to the base station apparatus 120B of the HHO destination cell 121B of the mobile station apparatus 130 of the identifier notified by the identification signal S11! The MBMS control information generation unit 113 is inquired by the inquiry signal S14 about whether or not the power is correct.

[0060] The MBMS control information generation unit 113 that has received the inquiry indicates that the corresponding MBMS is present when the corresponding MBMS is transmitted by the base station apparatus 120B by multicast communication, using the response signal S15. Notify MBMS reception confirmation section 116.

[0061] When the MBMS reception confirmation unit 116 confirms that there is a corresponding MBMS by notification from the MBMS control information generation unit 113, the MBMS identifier and the identifier of the mobile station device 130 that is the HHO target are determined as MBMS. The wireless information extraction unit 117 is notified by the reception confirmation signal S 12.

[0062] The wireless information extraction unit 117 that has received the notification is generated in the physical layer information used in the HHO destination base station device 120B of the mobile station device 130, that is, the MBMS control information generation unit 113. The base station control information generating unit 111 extracts the radio information transmitted by transmitting the MBMS control information, and the extracted radio information is transmitted to the dedicated channel control information generating unit 112 by the identifier of the mobile station apparatus 130. At the same time, the wireless information signal S3 is notified.

That is, radio information extraction section 117 is transmitted from base station apparatus 120 B of HHO destination cell 121 B of mobile station apparatus 130, and is generated by radio information, that is, MBMS control information generation section 113. The radio information generated by the base station control information generation unit 111 that carries the MBMS control information is sent to the dedicated channel control information generation unit 112 to the corresponding mobile station device. With the identifier of device 130.

[0064] The dedicated channel control information generation unit 112, which has received the notification by the radio information signal S3, uses the radio information extracted by the radio information extraction unit 117 from the base station control information generation unit 111 on the DCCH carrying control information related to the HHO. The base station apparatus 120A is also notified to the mobile station apparatus 130 before the HHO.

[0065] In this way, the dedicated channel control information generation unit 112 performs dedicated channel control on the physical layer information used in the base station device 120B that is the HHO destination before the mobile station device 130 executes the HHO. The base station device 120A notifies the mobile station device 130 as the DCCH information signal S5 of the information generator 112.

Next, with reference to the sequence shown in FIG. 4, a mobile station apparatus performing DPCH transmission / reception

The procedure of the radio control method of the present invention when the cell 121A power of the base station apparatus 120A is also HHOed to the cell 121B of the base station apparatus 120B while receiving 130-power MBMS will be described.

[0067] In FIG. 4, when starting reception of MBMS, mobile station apparatus 130 that is transmitting / receiving DPCH receives base station apparatus 120B of H121 cell 121B from base station apparatus 120A that is transmitting / receiving DPCH. The BCCH that transmits the broadcast information to be transmitted is acquired by receiving the PCCPCH.

[0068] In addition, the mobile station device 130 carries an MCCH that carries the MBMS control information related to the MBMS transmitted from the base station devices 120A and 120B generated by the MBMS control information generation unit 113. Setting information is acquired (step ST301).

[0069] Next, mobile station apparatus 130 acquires the MCCH that transmits the MBMS control information using the SCCPCH setting information acquired in step ST301 (step ST302), and the SCCPCH in which the MBMS is actually transmitted. Know your settings.

H and MTCH that transmits the contents of MBMS are included.

[0071] Next, the mobile station device 130 receives the MSCH that transmits the scheduling information of the MBMS being transmitted, thereby knowing the reception start timing and the reception time of the service received by itself, MBMS is received (step ST303). [0072] On the other hand, radio control apparatus 110 transmits, for example, a physical channel reconfiguration message and control information on DPDCH to cause HHO from cell 121A of base station apparatus 120A to cell 121B of base station apparatus 120B. The mobile station apparatus 130 is notified from the base station apparatus 120A of the cell 121A of the HHO source (step ST304).

[0073] Also, in step ST304, radio control apparatus 110 adds a SCCPCH message to the message notified from base station apparatus 120A of HHO source cell 121A to mobile station apparatus 130.

3 Add control information (eg spreading code information, timing information).

[0074] Next, the mobile station device 130 that has received the notification of the message from the base station device 120A performs HHO from the cell 121A to the cell 121B, and the uplink to the base station device 120B of the HHO destination cell 121B. A physical channel reconfiguration completion message is transmitted on the DCCH on the DPDCH of the same, and the fact that HHO has been performed from the cell 121A to the cell 121B is notified (step ST 305).

[0075] In this manner, radio control apparatus 110 can receive SCCPC H control information by means of a message notified from base station apparatus 120A of HHO source cell 121A in mobile station apparatus 130 step ST304.

Three

[0076] Thereby, the mobile station apparatus 130, in step ST304, performs uplink D related to the HHO.

By receiving the DCCH on the PDCH, it is possible to know the physical layer settings for carrying the MCCH that carries the MBMS control information.

Therefore, in radio control apparatus 110, a step for receiving the BCCH for transmitting broadcast information transmitted by base station apparatus 120B of cell 121B of the HHO destination (conventional information shown in FIG. 1) Step ST406) in the radio control method becomes unnecessary.

That is, in radio control apparatus 110, mobile station apparatus 130 that performs HHO sets the SCCPCH that carries the MBMS control information transmitted by base station apparatus 120B of H121 cell 121B before performing HHO. I can know.

[0079] Therefore, in the wireless control device 110, after the end of the HHO as in the conventional wireless control method, the M

No need to receive broadcast information to resume BMS reception HHO source cell 12

The 1A base station device 120A can also receive MCCH that transmits MBMS control information in advance. [0080] Thereby, in radio control apparatus 110, mobile station apparatus 130 transmits MBMS control information using the SCCPCH setting information acquired in step ST304 immediately after HHO.

H and MTCH force to transmit the contents of MBMS are included.

[0082] Thereby, the mobile station apparatus 130 receives the MSCH that transmits the MBMS scheduling information being transmitted, thereby knowing the MBMS reception start timing and reception time received by the mobile station apparatus 130, MBMS can be received (step ST307

) o

[0083] As described above, in radio control apparatus 110, mobile station apparatus 130 urging implementation of HHO determines whether it is receiving MBMS by multicast communication, and determines that it is being implemented. Control information related to MBMS can be transmitted to the mobile station device 130 in the HHO destination cell 121B, and the setting information related to SCCPCH can be reported on the control information related to HHO.

Therefore, in radio control apparatus 110, mobile station apparatus 130 receives SC CPCH transmitting control information related to MBMS immediately after HHOing to cell 121B of base station apparatus 120B that is the HHO destination. To reduce MBMS reception interruption time by HHO

Can do.

[0085] It should be noted that radio control apparatus 110 shown in FIG. 3 has SCCPCH setting information for carrying MCCH carrying MBMS control information on DCCH on uplink DPDCH related to HHO.

However, the radio information extraction unit 117 may notify the mobile station device 130 of the setting information of the SCCPCH carrying the MBMS itself that the mobile station device 130 should receive.

Yes.

[0086] Thus, since the mobile station device 130 can know the setting of the physical layer carrying the MBMS after completing the HHO, it can receive the SCCPCH immediately after the HHO.

Four

MBMS reception interruption time by HO can be shortened.

In radio control apparatus 110, MBMS reception confirmation unit 116 moves at identification unit 115. When the station device 130 determines that there is an MBMS service being received, the MCC H information for the base station device 120B of the HHO destination cell 121B generated by the MBMS control information generation unit 113 is used as the dedicated channel control information generation unit.
