20130022011 | MOBILE COMMUNICATION SYSTEM, BASE STATION APPARATUS, MOBILE STATION APPARATUS, MOBILE COMMUNICATION METHOD, AND INTEGRATED CIRCUIT - Provided are a mobile communication system and a mobile communication method in which a base station apparatus and a mobile station apparatus can efficiently transmit control information in case of communication is conducted by using a wide frequency band constructed by a plurality of component carriers. The mobile communication system in which the base station apparatus and the mobile station apparatus communicate by using the plurality of component carriers, wherein the base station apparatus allocates resources to the mobile station apparatus for transmitting HARQ control information, and the mobile station apparatus uses the allocated resources to transmit to the base station apparatus the HARQ control information for a physical downlink control channel and/or a physical downlink shared channel which are transmitted on a plurality of downlink component carriers, and also a scheduling request for requesting the allocation of uplink data transmission. | 01-24-2013 |
20130279394 | MOBILE COMMUNICATION SYSTEM, MOBILE STATION DEVICE, BASE STATION DEVICE, SGSN, GGSN, MME, MBMS GW AND MOBILE COMMUNICATION METHOD - To provide a mobile communication system and the like that can efficiently use network resources, by defining a control method of releasing network resources by a counting function of a base station device. In a mobile communication system that performs distribution of broadcast data by an MBMS bearer service, from a BM-SC to a mobile station device that is connected to a base station device, via a GGSN and an SGSN for which an MBMS bearer has been established, the base station device transmits a session stop request associated with the MBMS bearer context to the SGSN when stopping the distribution of broadcast data associated with a flow identifier included in an MBMS bearer context, and stops distribution of broadcast data. | 10-24-2013 |
20130279395 | MOBILE COMMUNICATION SYSTEM, MOBILE STATION DEVICE, BASE STATION DEVICE, SGSN, GGSN, MME, MBMS GW AND MOBILE COMMUNICATION METHOD - To provide a mobile communication system and the like that can efficiently use network resources, by defining a control method of releasing network resources by a counting function of a base station device. In a mobile communication system that performs distribution of broadcast data by an MBMS bearer service, from a BM-SC to a mobile station device that is connected to a base station device, via a GGSN and an SGSN for which an MBMS bearer has been established, the base station device transmits a session stop request associated with the MBMS bearer context to the SGSN when stopping the distribution of broadcast data associated with the MBMS bearer context, and stops distribution of broadcast data to thereby release the MBMS bearer resources between the base station device and the SGSN. | 10-24-2013 |
20130315130 | MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, SGSN, AND MOBILE STATION DEVICE - 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. | 11-28-2013 |
20140233465 | UE, ANDSF, MOBILE COMMUNICATION SYSTEM, PGW, AND COMMUNICATION METHOD - UE receives a mobile operator policy including flow identification information, access system identification information, and a degree of compulsion from an ANDSF, and in a case where the degree of compulsion included in the mobile operator policy is a degree of compulsion that compels the UE to perform switching, transmits a request to forcibly switch a communication path used flow communication corresponding to the flow identification information to an access system corresponding to the access system identification information included in the mobile operator policy. As a result, by transmitting an MO policy from the ANDSF to the UE while the UE connected to a first access system is performing data communication, the UE changes a UE policy to the MO policy, thereby providing a mobile communication system or the like that is capable of avoiding concentration of traffic in the first access system. | 08-21-2014 |
20140321429 | HOME BASE STATION DEVICE, MOBILE COMMUNICATION SYSTEM, MOBILE TERMINAL DEVICE, AND POSITION MANAGEMENT DEVICE - A mobile communication system and so on are provided in which an LIPA handover procedure utilizing a management table can be started by transmitting a handover request from a home base station device to which a mobile terminal device is connected, and by transmitting a response to the handover request from another home base station device. In the mobile communication system in which, in the case of handover being performed for the mobile terminal device to some other home base station device, one home base station device adaptable for the LIPA handover is determined, as a handover target, from the management table, the management table is updated such that when an address of a gateway device is contained in the handover request, the LIPA handover is enable, and when the address of the gateway device is not contained in the handover request, the LIPA handover is disable. | 10-30-2014 |
20150098428 | MOBILE COMMUNICATION SYSTEM, BASE STATION APPARATUS, MOBILE STATION APPARATUS, MOBILE COMMUNICATION METHOD, AND INTEGRATED CIRCUIT - Provided are a mobile communication system and a mobile communication method in which a base station apparatus and a mobile station apparatus can efficiently transmit control information in case of communication is conducted by using a wide frequency band constructed by a plurality of component carriers. The mobile communication system in which the base station apparatus and the mobile station apparatus communicate by using the plurality of component carriers, wherein the base station apparatus allocates resources to the mobile station apparatus for transmitting HARQ control information, and the mobile station apparatus uses the allocated resources to transmit to the base station apparatus the HARQ control information for a physical downlink control channel and/or a physical downlink shared channel which are transmitted on a plurality of downlink component carriers, and also a scheduling request for requesting the allocation of uplink data transmission. | 04-09-2015 |
20150146533 | MOBILE COMMUNICATION SYSTEM, HOME BASE STATION DEVICE, POSITION MANAGING DEVICE, COMMUNICATION METHOD, AND MOBILE STATION DEVICE - Provided is a mobile communication system in which a SIPTO@LN capable LGW is selected and a PDN connection is established during a GW selection process of an MME in a PDN connection establishment procedure.
