Abstract | This gateway device (20) is arranged between: an eNB (10) that performs communications in accordance with S1AP; and an MME (30) or an MME (32). The gateway device (20) comprises: a communication unit (21) that terminates an S1AP message transmitted from the eNB (10); a determination unit (22) that determines the terminal type of UE (40) associated with the S1AP message; and a conversion unit (23) that changes a transmission source address set for the S1AP message transmitted from the eNB from an identifier for the eNB (10) to a first identifier for the gateway device (20). The communication unit (21) transmits, to MME (30) or MME (32) as decided in accordance with the terminal type, the S1AP message for which the transmission source address was converted.
L'invention concerne un dispositif passerelle (20) qui est disposé entre : un eNB (10) qui exécute des communications conformément à S1AP; et une MME (30) ou une MME (32). Le dispositif passerelle (20) comprend : une unité de communication (21) qui termine un message S1AP émis depuis l'eNB (10); une unité de détermination (22) qui détermine le type de terminal d'UE (40) associé au message S1AP; et une unité de conversion (23) qui modifie une adresse source d'émission définie pour le message S1AP émis depuis l'eNB d'un identificateur pour l'eNB (10) à un premier identificateur pour le dispositif passerelle (20). L'unité de communication (21) transmet, à une MME (30) ou une MME (32), suivant la décision conformément au type de terminal, le message S1AP pour lequel l'adresse source d'émisison a été convertie.
本発明にかかるゲートウェイ装置(20)は、S1APに従って通信を実行するeNB(10)とMME(30)もしくはMME(32)との間に配置されるゲートウェイ装置である。ゲートウェイ装置(20)は、eNB(10)から送信されたS1APメッセージを終端する通信部(21)と、S1APメッセージに関連付けられたUE(40)の端末種別を判定する判定部(22)と、eNB(10)から送信されたS1APメッセージに設定されている送信元アドレスを、eNB(10)の識別子からゲートウェイ装置(20)の第1の識別子に変更する変換部(23)と、を備え、通信部(21)は、送信元アドレスが変換されたS1APメッセージを、端末種別に応じて決定されるMME(30)もしくはMME(32)へ送信する。 |
