移動通信システム、基地局装置及び移動局装置
Document Type and Number:
Japanese Patent JP5718670
Kind Code:
B2
Abstract:
With an MBMS bearer service, information about an MBMS bearer which allocates and establishes MBMS bearer resources is included in an MBMS bearer context, with a base station device (NB) transmitting a confirmation message containing a service identifier to mobile station devices (UE) and, based on responses from the mobile station devices (UE), counting the number of mobile station devices (UE) participating in multicast data distribution. In the event that the number counted is 0, an MBMS registration deletion request for the multicast data is transmitted to an SGSN. Thus, by stipulating a control method using the counting function of the base station device to efficiently allocate network resources, a mobile communication system or the like capable of effectively using the network resources can be provided.
