20130010689 | MOBILE COMMUNICATION METHOD, SWITCH, AND SUBSCRIBER INFORMATION SERVER - A mobile communication method according to the present invention includes a step A in which, in location registration processing of a mobile station, an switch of a first communication scheme and an switch of a second communication scheme send a subscriber information server first information used to determine whether or not all coverage areas have a same capability of providing a telephony service by packet switching; and a step B in which, when a status inquiry request made upon receipt of a terminating-call signal destined for the mobile station is received from an application server, the subscriber information server determines based on the first information whether or not to make an inquiry at the switch of the first communication scheme or the switch of the second communication scheme about whether or not provision of the telephony service by packet switching is possible in an area where the mobile station is located. | 01-10-2013 |
20130115917 | MOBILE COMMUNICATION METHOD, SWITCH, AND MOBILE STATION - A mobile communication method according to the present invention includes the steps of: causing an switch MME to perform CSFB-related processing for a mobile station UE when receiving “Extended Service Request” during call restriction and judging that the mobile station UE supports the barring scheme for CSFB on the basis of CSFB restriction capability information; and causing the switch MME to send the mobile station UE “Service Reject” when receiving “Extended Service Request” during the call restriction and judging that the mobile station UE does not support the barring scheme for CSFB on the basis of the CSFB restriction capability information. | 05-09-2013 |
20130143559 | MOBILE COMMUNICATION METHOD AND CORE NETWORK APPARATUS - A mobile communication method according to the present invention includes a step A in which an SGSN/MME determines whether to allow a UE to turn into an always-on state in which a bearer for a UE is always established in a core network when “Attach Request” or “RA Update Request/TA Update Request” is received from the UE, and a step B in which the SGSN/MME transmits always-on information indicating the determination result to the UE by using “Attach Accept” or “RA Update Accept/TA Update Accept”. | 06-06-2013 |
20130155951 | MOBILE STATION AND RADIO BASE STATION - A mobile station UE according to the present invention includes a notification reception unit | 06-20-2013 |
20140010185 | MOBILE COMMUNICATION METHOD AND MOBILITY MANAGEMENT NODE - A mobile communication method according to the present invention includes: a step A of causing a UE to send a MME accommodating an E-UTRAN a “LTE Attach Request” including capability information indicating whether or not the UE supports “VoLTE communications”; and a step B of causing the MME to judge whether or not to establish an IMS APN bearer between the UE and an IMS APN on the basis of the capability information when judging that an APN of the UE is the IMS APN. | 01-09-2014 |
20140045493 | MOBILE COMMUNICATION METHOD, MOBILE MANAGEMENT NODE, AND SUBSCRIBER MANAGEMENT SERVER - To enable control such that a roaming mobile station UE is not instructed to perform MDT. A mobile communication method according to the present invention includes: a step of determining, by a mobile management node MME, whether a mobile station UE is a roaming mobile station UE (Roaming User), in an Attach procedure of a mobile station UE or a transition procedure to an Active state; and a step of transmitting, by the mobile management node MME, to a radio base station eNB, “User Consent Indication” indicating that the mobile station UE has not given consent for implementation of MDT when it is determined that the mobile station UE is a roaming mobile station UE. | 02-13-2014 |
20140056135 | MOBILE STATION - A mobile station UE according to the present invention includes a control unit | 02-27-2014 |
20140066021 | MOBILE COMMUNICATION METHOD, RADIO BASE STATION AND MOBILE MANAGEMENT NODE - Control is performed such that an instruction is not provided to a mobile station UE, which becomes a roaming state by handover, to perform MDT. A mobile communication method according to the present invention includes a step in which a radio base station eNB# | 03-06-2014 |
20140119192 | MOBILE COMMUNICATION METHOD, MOBILE COMMUNICATION SYSTEM AND RADIO BASE STATION - When congestion in an eNB is detected, effective utilization of resources is achieved by adjusting not only a data flow rate in an EPS-RAB but also a band of a core network bearer corresponding with the EPS-RAB. A mobile communication method according to an embodiment includes a step A of causing an eNB to notify an MME of a cause of congestion and identifier information of the EPS-RAB involved in the congestion, when the eNB detects the congestion. | 05-01-2014 |
20140133432 | MOBILE COMMUNICATION METHOD AND CALL SESSION CONTROL SERVER APPARATUS - The invention avoids unnecessary transmission of signals, and shortens time for establishing a bearer for a UE. A mobile communication method of an embodiment includes the steps of: notifying, by a P-CSCF, when the P-CSCF receives a SIP signal # | 05-15-2014 |
20140185525 | MOBILE COMMUNICATION METHOD AND APPLICATION SERVER APPARATUS - A mobile communication method according to the present invention includes the steps of: when an S-CSCF in an IMS receives a terminating signal directed to a UE, sending the terminating signal from the S-CSCF to an SCC-AS in the IMS, the terminating signal including call-type information indicating whether the terminating signal is for voice communication or AV communication; sending an inquiry signal including the call-type information from the SCC-AS to an HSS; and determining, by the SCC-AS, a domain to which the terminating signal is to be transferred, based on the call-type information and a response signal received from the HSS as a response to the inquiry signal. | 07-03-2014 |
20140219171 | MOBILE COMMUNICATION METHOD AND MOBILITY MANAGEMENT NODE - A mobile station UE chooses an appropriate domain for originating AV communication without causing connection delay even when roaming. A mobile communication method according to the present invention includes the steps of: causing a mobility management node MME in an LTE network to send a mobile station UE “ATTACH ACCEPT” containing AV communication provision capability information indicating a capability of providing AV communication in the LTE network; and causing the mobile station UE to determine, based on the AV communication provision capability information, whether to perform the AV communication via an IMS or to perform the AV communication by circuit switching communication. | 08-07-2014 |
