Description

移動局Mobile station
　本発明は、移動局に関する。 The present invention relates to a mobile station.
　ＬＴＥ（Ｌｏｎｇ　Ｔｅｒｍ　Ｅｖｏｌｕｔｉｏｎ）方式のＲｅｌｅａｓｅ-１２では、「Ｐｒｏｘｉｍｉｔｙ　Ｓｅｒｖｉｃｅ（ＰｒｏＳｅ）　ＷＩ」において、「Ｄ２Ｄ（Ｄｅｖｉｃｅ　ｔｏ　Ｄｅｖｉｃｅ）　ｃｏｍｍｕｎｉｃａｔｉｏｎ」の検討が始まっている。 In Release-12 of LTE (Long Term Evolution), “D2D (Device to Device) communication” is being studied in “Proximity Service (ProSe) WI”.
　かかる「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」の検討では、「Ｐｕｂｌｉｃ　Ｓａｆｅｔｙ」及び「Ｃｏｍｍｅｒｃｉａｌ」という２つのシナリオが対象となっている。 In the examination of the “D2D communication”, two scenarios “Public Safety” and “Commercial” are targeted.
　「Ｐｕｂｌｉｃ　Ｓａｆｅｔｙ」は、災害時等で通信事業者のネットワークが故障した場合に、警察や消防署等の政府機関が「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」を行うケースをユースケースとして想定している。 “Public Safety” assumes a case where a government agency such as the police or a fire department performs “D2D communication” when a network of a communication carrier breaks down due to a disaster or the like as a use case.
　「Ｐｕｂｌｉｃ　Ｓａｆｅｔｙ」では、セルラー方式の移動通信システムと異なる移動通信システムが用いられる。 “Public Safety” uses a mobile communication system different from the cellular mobile communication system.
　一方、「Ｃｏｍｍｅｒｃｉａｌ」は、ＳＮＳ（Ｓｏｃｉａｌ　Ｎｅｔｗｏｒｋ　Ｓｙｓｔｅｍ）や広告配布等のために、移動局ＵＥ同士で「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」を行うケースをユースケースとして想定している。 On the other hand, “Commercial” assumes a case where “D2D communication” is performed between mobile stations UE for use in SNS (Social Network System), advertisement distribution, and the like.
　ＬＴＥ方式の移動通信システムでは、政府機関等からの要求に応じて、通信事業者は、「Ｌａｗｆｕｌ　Ｉｎｔｅｒｃｅｐｔｉｏｎ（政府機関による通信傍受）」を行うことが必須である、すなわち、移動局ＵＥ同士の通信内容を提供することが必須である。 In the LTE mobile communication system, it is indispensable for the communication carrier to perform “Lawful Interception” in response to a request from a government agency, that is, communication between mobile stations UE. It is essential to provide content.
　ここで、「Ｐｕｂｌｉｃ　Ｓａｆｅｔｙ」を目的とする「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」は、政府機関によって行われる通信であるため、「Ｐｕｂｌｉｃ　Ｓａｆｅｔｙ」を目的として移動局ＵＥ間で直接通信を行う「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」に対して「Ｌａｗｆｕｌ　Ｉｎｔｅｒｃｅｐｔｉｏｎ」を行う必要はない。 Here, since “D2D communication” for the purpose of “Public Safety” is communication performed by a government agency, for “D2D communication” for direct communication between mobile stations UE for the purpose of “Public Safety” There is no need to perform “Lawful Interception”.
　一方、「Ｃｏｍｍｅｒｃｉａｌ」を目的とする「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」は、通常の移動局ＵＥ同士の通信と同じ扱いになるため、「Ｃｏｍｍｅｒｃｉａｌ」を目的として移動局ＵＥ間で直接通信を行う「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」に対して「Ｌａｗｆｕｌ　Ｉｎｔｅｒｃｅｐｔｉｏｎ」を行う必要がある。 On the other hand, “D2D communication” for the purpose of “Commercial” is handled in the same way as communication between normal mobile stations UE, so “D2D communication” for direct communication between mobile stations UE for the purpose of “Commercial”. On the other hand, it is necessary to perform “Lawful Interception”.
　しかしながら、既存のＬＴＥ方式における「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」では、通信事業者は、通信内容を監視することができず、「Ｌａｗｆｕｌ　Ｉｎｔｅｒｃｅｐｔｉｏｎ」を行うことができないという問題点があった。 However, in the “D2D communication” in the existing LTE system, there is a problem that the communication carrier cannot monitor the communication content and cannot perform “Lawful Interception”.
　そこで、本発明は、上述の課題に鑑みてなされたものであり、「Ｄ２Ｄ　ｃｏｍｍｕｎｉｃａｔｉｏｎ」において、「Ｌａｗｆｕｌ　Ｉｎｔｅｒｃｅｐｔｉｏｎ」を行うことを可能とする移動局を提供することを目的とする。 Therefore, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a mobile station that can perform “Lawful Interception” in “D2D communication”.
　本発明の第１の特徴は、他の移動局との間で直接通信を行うことできるように構成されている移動局であって、前記他の移動局との間で行われた通信内容を記憶するように構成されている記憶部と、無線基地局からの指示に応じて、該無線基地局に対して、前記記憶部によって記憶されている前記通信内容を報告するように構成されている通信部とを具備することを要旨とする。 A first feature of the present invention is a mobile station configured to be able to directly communicate with another mobile station, and the contents of communication performed with the other mobile station are A storage unit configured to store, and configured to report the communication content stored in the storage unit to the radio base station in response to an instruction from the radio base station And a communication unit.
