  • the radio information extracting means replaces the MCCH related to the service being received by the mobile station device with setting information related to the SCCPCH being transmitted, Then, the mobile station apparatus receives the service! /, Transmits the service, extracts the SCCPCH setting information, and transmits the extracted setting information on the MCCH carrying the control information on the HHO.
  • a configuration is adopted in which the mobile station apparatus is notified.
  • the mobile station apparatus when the mobile station apparatus completes the HHO, the mobile station apparatus can know the setting of the physical layer that carries the service. Therefore, the mobile station apparatus can receive the SCCPCH immediately after the HHO, The reception interruption time of the service by HHO can be shortened.
  • One aspect of the radio network controller of the present invention is that, instead of the identification unit and the radio information extraction unit, the reception confirmation unit confirms that the mobile station device is receiving the service.
  • the mobile station apparatus is notified of information on the service being transmitted at the HHO destination on the DCCH before the HHO.
  • the mobile station apparatus when the mobile station apparatus receives the DCCH of control information related to the HHO, the mobile station apparatus can know the MCCH information transmitted from the base station apparatus of the HHO destination! Therefore, according to this configuration, the mobile station apparatus is the base station apparatus of the HHO destination cell.
  • Information related to the MBMS to be received such as SCCPCH configuration information, can be known from the MCCH information being transmitted, so SCCPCH can be received immediately after HHO, and MBMS reception by HHO The interruption time can be shortened.
  • One aspect of the mobile station apparatus of the present invention includes: a receiving unit that receives, on the DPCH, setting information of SCCPCH transmitting a service by multicast communication transmitted from the radio control apparatus; and the receiving unit A multicast service receiving unit that receives a service by multicast communication based on the content of the received setting information of the SCCPCH is adopted.
  • the mobile station apparatus receives in advance the M CCH that transmits the control information related to the service without receiving the broadcast information transmitted in the HHO destination cell after the end of the HHO. And the reception interruption time of the service by HHO can be shortened.
  • the receiving unit includes the control information itself of the service of the HHO destination cell, which is inserted together with signaling that prompts the HHO in the radio control apparatus.
  • the HHO destination cell recognizes the presence of the service registered by itself and has a function of knowing the physical channel settings to be received after the HHO.
  • the mobile station apparatus recognizes that a service that it wants to receive is being implemented at the HHO destination, and broadcast information transmitted in the HHO destination cell after the HHO. Can start receiving the service without receiving new or MCCH industrial applicability
  • the radio control apparatus, mobile station apparatus, and radio control method according to the present invention can shorten the time until reception of a service by multicast communication can be started in the HHO destination cell. This is useful as a radio control apparatus, mobile station apparatus, and radio control method for performing HHO control when a mobile station apparatus capable of simultaneously receiving a service based on DPCH and communication using DPCH.

Abstract

Dispositif de commande sans fil pouvant réduire l'heure à laquelle la réception d'un service MBMS dans une cellule de destination de 'hard handover' (HHO) est prête à démarrer. Le dispositif de commande sans fil (110) exécute la commande de HHO d'un dispositif formant station mobile (130) pouvant simultanément recevoir à la fois un service de communication multidiffusé (MBMS) et une communication DPCH. Une partie d'extraction d'informations sans fil (117) extrait les informations de réglage d'un SCCPCH durant la transmission d'un MCCH qui transmet les informations de commande associées au service MBMS dans une cellule de destination de HHO du dispositif formant station mobile (130). Des moyens de notification notifient les informations de réglage extraites par la partie d'extraction d'informations sans fil (117) au dispositif formant station mobile (130) via le dispositif formant station de base (120A) de la cellule source du HHO sur un DCCH qui transmet les informations de commande associées au HHO du dispositif formant station mobile (130) avant le HHO du dispositif formant station mobile (130).
