摘要:
A mobile communication method according to the present invention includes the steps of : causing an MME#1 after restart not only to transmit “Paging” to a UE but also to transmit “Delete Session Request” containing IMSI of the UE and “Cause=MME restart” to an S-GW#1, when receiving “Downlink Data Notification” containing the IMSI of the UE from the S-GW#1; causing the S-GW#1 not only to release a bearer for the UE but also to transmit the “Delete Session Request” containing the “Cause=MME restart” to the P-GW#1, upon receipt of the “Delete Session Request”; and causing the P-GW#1 to release the bearer for the UE.
摘要:
A message distribution method according to the present invention includes the steps of: (A) determining, at a message distribution station (CBC), distribution area information and a distribution type, based on a message distribution request received from a flash report transmission station (CBE) and containing distribution target area information, and reporting, from the message distribution station (CBC) to a radio base station (eNB), the distribution area information and the distribution; and (B) determining, at the radio base station (eNB), the distribution area, based on the distribution area information and the distribution type, and distributing, from the radio base station to the mobile station in the distribution area, a predetermined message.
摘要:
The characteristic of a mobile communication system according to the present invention is that the mobile communication system includes the steps of: causing an MME in a visitor network of UE#1 to acquire SRVCC capability of the UE#1 and to notify an HSS of the SRVCC capability of the UE#1 in an attach process or location registration process of the UE#1; and causing an ATCF, which controls an ATGW, to acquire the SRVCC capability of the UE#1, in a registration process of the UE#1 with IMS.
摘要:
A mobile communication method according to the present invention includes a step A of causing an SCC-AS to transmit an inquiry signal to an HSS when the SCC-AS receives “Invite” addressed to a UE; a step B of causing the HSS to transmit a paging request signal; a step C of causing the HSS to determine a RAT which the UE is served in response to a paging result notification signal including a paging result in at least one of an UTRAN/GERAN and an E-UTRAN; a step D of causing the HSS to transmit serving area information of the UE including information on the RAT which the UE is served to the SCC-AS/S-CSCF; and a step E of causing the SCC-AS/S-CSCF to transfer the “Invite” addressed to the UE, to the UTRAN/GERAN or the E-UTRAN using a terminating call scheme selected based on the serving area information of the UE.
摘要:
A mobile communication method according to the present invention includes the steps of: transmitting an “Extended Service Request” from a mobile station UE in Idle mode to a mobility management node MME via a radio base station eNodeB; transmitting an “Initial UE Context Setup Request” from the mobile station UE to the radio base station eNodeB, the “Initial UE Context Setup Request containing priority call information; and preferentially allocating resources to the E-RAB for the mobile station UE by the radio base station eNodeB based on the priority call information contained in the received “Initial UE Context Setup Request.”

摘要:
The mobile communication method according to the present invention includes: a step of acquiring and storing, by a mobile management node MME, Cell-ID for identifying a cell in which a mobile station UE exists, in an MM process; a step of transmitting, by the mobile management node MME, a positioning process signal “Location Request” including the stored Cell-ID to a positioning calculation node E-SMLC, in an LCS process; and a step of performing, by the positioning calculation node E-SMLC, a positioning process of the mobile station UE, using the Cell-ID included in the received positioning process signal “Location Request”, in the LCS process.
摘要:
In a mobile communication system capable of switching between a first communication state and a second communication state, in a case of a first communication state, a VoIP media signal is exchanged between a mobile station. UE #1 and a mobile station UE #2 via an LTE radio access system and a node S-GW, a VoIP control signal is exchanged via the LTE radio access system, the node S-GW, and IMS, and in a case of a second communication state, a circuit-switched signal is exchanged between the mobile station UE #1 and an enhanced MSC/MGW via a 2G/3G radio access system, the VoIP media signal is exchanged between the enhanced MSC/MGW and the mobile station UE #2 via the node S-GW, and the VoIP control signal is exchanged between the enhanced MSC/MGW and the mobile station UE #2 via the node S-GW and the IMS.
