Abstract

Using a UE-led "T-ADS" and without being only for an incoming signal for voice communication addressed to a UE, the present invention suitably selects a domain that is to forward an incoming signal for AV communication addressed to the UE. This mobile communication method has: a step wherein, when a UE is in a cell under an E-UTRAN, an IMS transmits to the UE via the E-UTRAN an incoming indication signal indicating that the IMS has received an incoming signal addressed to the UE; a step wherein, when the UE has determined that the type of the incoming signal addressed to the UE is AV communication, the UE transmits to the IMS a "REJECT" indicating that AV communication via the IMS cannot be supported; and a step wherein the IMS decides to provide AV communication that uses CSFB to the UE in response to the "REJECT".

Description

移動通信方法及び移動局Mobile communication method and mobile station
　本発明は、移動通信方法及び移動局に関する。 The present invention relates to a mobile communication method and a mobile station.
　従来、２Ｇ/３Ｇ方式の無線アクセスシステム（ＵＴＲＡＮ：Ｕｎｉｖｅｒｓａｌ　Ｔｅｒｒｅｓｔｒｉａｌ　Ｒａｄｉｏ　Ａｃｃｅｓｓ　Ｎｅｔｗｏｒｋ/ＧＥＲＡＮ：ＧＳＭ　ＥＤＧＥ　Ｒａｄｉｏ　Ａｃｃｅｓｓ　Ｎｅｔｗｏｒｋ）及びＬＴＥ（Ｌｏｎｇ　Ｔｅｒｍ　Ｅｖｏｌｕｔｉｏｎ）方式の無線アクセスシステム（Ｅ-ＵＴＲＡＮ：Ｅｖｏｌｖｅｄ　Ｕｎｉｖｅｒｓａｌ　Ｔｅｒｒｅｓｔｒｉａｌ　Ｒａｄｉｏ　Ａｃｃｅｓｓ　Ｎｅｔｗｏｒｋ）を収容可能な移動通信システムが知られている。 Conventionally, 2G / 3G wireless access system (UTRAN: Universal Terrestrial Radio Access Network / GERAN: GSM EDGE Radio Access Network) and LTE (Long Term Evolver TR system). ) Is known.
　かかる移動通信システムにおいて、ＵＴＲＡＮ/ＧＥＲＡＮ及びＥ-ＵＴＲＡＮの両方にアクセス可能なＵＥ（Ｕｓｅｒ　Ｅｑｕｉｐｍｅｎｔ、移動局）に対して、ＵＴＲＡＮ/ＧＥＲＡＮ或いはＥ-ＵＴＲＡＮのどちらかにおいて音声（Ｖｏｉｃｅ）通信を提供することができる。 In such a mobile communication system, a voice communication is provided in either UTRAN / GERAN or E-UTRAN to a UE (User Equipment, a mobile station) that can access both UTRAN / GERAN and E-UTRAN. be able to.
　ここで、かかる移動通信システムでは、ＵＥ主導型の「Ｔ-ＡＤＳ（Ｔｅｒｍｉｎａｔｅｄ-Ａｃｃｅｓｓ　Ｄｏｍａｉｎ　Ｓｅｌｅｃｔｉｏｎ）」を用いて、ＵＥに対して音声通信を提供するドメインを選択することができるように構成されている（非特許文献１及び２参照）。 Here, the mobile communication system is configured to be able to select a domain that provides voice communication to the UE using UE-driven “T-ADS (Terminated-Access Domain Selection)”. (See Non-Patent Documents 1 and 2).
　図４を参照して、かかるＵＥ主導型の「Ｔ-ＡＤＳ」を用いてＵＥに対して音声通信を提供するドメインを選択する動作について説明する。 Referring to FIG. 4, the operation of selecting a domain that provides voice communication to the UE using the UE-driven “T-ADS” will be described.
　図４に示すように、ＩＭＳ（ＩＰ　Ｍｕｌｔｉｍｅｄｉａ　Ｓｕｂｓｙｓｔｅｍ、サービス制御ネットワーク）内のＳ-ＣＳＣＦ（Ｓｅｒｖｉｎｇ　Ｃａｌｌ　Ｓｅｓｓｉｏｎ　Ｃｏｎｔｒｏｌ　Ｆｕｎｃｔｉｏｎ、呼セッション制御サーバ装置）は、ステップＳ５０１において、ＵＥ宛ての音声通信用の着信信号（Ｉｎｖｉｔｅ＠Ｖｏｉｃｅ）を受信すると、ステップＳ５０２において、ＩＭＳ内のＳＣＣ-ＡＳ（Ｓｅｒｖｉｃｅ　Ｃｅｎｔｒａｌｉｚａｔｉｏｎ　ａｎｄ　Ｃｏｎｔｉｎｕｉｔｙ　Ａｐｐｌｉｃａｔｉｏｎ　Ｓｅｒｖｅｒ、アプリケーションサーバ装置）に対して、かかる音声通信用の着信信号（Ｉｎｖｉｔｅ）を送信する。 As shown in FIG. 4, the S-CSCF (Serving Call Session Function, call session control server device) in the IMS (IP Multimedia Subsystem, service control network) receives an incoming signal for voice communication addressed to the UE in step S501. When (Invite @ Voice) is received, in step S502, an incoming signal (Invite) for voice communication is transmitted to the SCC-AS (Service Centralization and Continuity Application Server, application server device) in the IMS.
　ステップＳ５０３において、ＳＣＣ-ＡＳは、ＨＳＳ（Ｈｏｍｅ　Ｓｕｂｓｃｒｉｂｅｒ　Ｓｅｒｖｅｒ、加入者管理サーバ装置）に対して、問合せ信号を送信する。 In step S503, the SCC-AS transmits an inquiry signal to the HSS (Home Subscriber Server, subscriber management server device).
　ステップＳ５０４において、ＨＳＳは、かかる問合せ信号に応じて、ＳＧＳＮ（Ｓｅｒｖｉｎｇ　ＧＰＲＳ　Ｓｕｐｐｏｒｔ　Ｎｏｄｅ、パケット交換機）及びＭＭＥに対して、ＵＥの在圏するドメインを問い合わせるドメイン問合せ信号を送信する。 In step S504, in response to the inquiry signal, the HSS transmits a domain inquiry signal for inquiring about the domain where the UE is located to the SGSN (Serving GPRS Support Node, packet switch) and the MME.
　ステップＳ５０５において、ＨＳＳは、ＳＣＣ-ＡＳに対して、上述の問合せ信号に対する応答信号を送信することによって、ＵＥの在圏するドメイン（図４の例では、Ｅ-ＵＴＲＡＮ）を通知する。 In step S505, the HSS notifies the SCC-AS of the domain in which the UE is located (E-UTRAN in the example of FIG. 4) by transmitting a response signal to the above inquiry signal.
　ＳＣＣ-ＡＳは、ステップＳ５０６において、かかる応答信号に応じて、ＵＥ宛ての音声通信用の着信信号を転送すべきドメイン（図４の例では、Ｅ-ＵＴＲＡＮ）を決定し、Ｓ-ＣＳＣＦに対して、Ｅ-ＵＴＲＡＮに対してＵＥ宛ての音声通信用の着信信号を転送するように指示する着信ドメイン指示信号を送信する。 In step S506, the SCC-AS determines a domain (E-UTRAN in the example of FIG. 4) to which an incoming signal for voice communication addressed to the UE should be transferred in response to the response signal. Then, an incoming domain instruction signal for instructing E-UTRAN to transfer an incoming signal for voice communication addressed to the UE is transmitted.
　ステップＳ５０７及びＳ５０８において、Ｓ-ＣＳＣＦは、着信ドメイン指示信号によって指示されているＥ-ＵＴＲＡＮを介して、ＵＥに対して、ＵＥ宛ての音声通信用の着信信号を受信した旨を指示する着信指示信号を送信する。 In Steps S507 and S508, the S-CSCF instructs the UE that the incoming signal for voice communication addressed to the UE has been received via the E-UTRAN indicated by the incoming domain indication signal. Send a signal.
　ここで、ＵＥは、ＵＥの能力やＥ-ＵＴＲＡＮの能力に応じて、ＩＭＳを介した音声通信に対応することができないと決定した場合に、ステップＳ５０９及びＳ５１０において、Ｅ-ＵＴＲＡＮを介して、Ｓ-ＣＳＣＦに対して、ＩＭＳを介した音声通信に対応することができない旨を示す「ＲＥＪＥＣＴ」を送信する。 Here, when it is determined that the UE cannot support voice communication via IMS according to the capability of the UE or the capability of E-UTRAN, in step S509 and S510, the UE via the E-UTRAN, “REJECT” indicating that voice communication via IMS cannot be supported is transmitted to the S-CSCF.
　ステップＳ５１１において、Ｓ-ＣＳＣＦは、ＳＣＣ-ＡＳに対して、かかる「ＲＥＪＥＣＴ」を送信する。 In step S511, the S-CSCF transmits such “REJECT” to the SCC-AS.
　ステップ５１２において、ＳＣＣ-ＡＳは、かかる「ＲＥＪＥＣＴ」に応じて、ＵＥに対して、ＣＳＦＢを用いた音声通信を提供することを決定する。 In step 512, the SCC-AS determines to provide voice communication using CSFB to the UE in response to the “REJECT”.
　なお、上述の移動通信システムにおいて、ＵＴＲＡＮ/ＧＥＲＡＮ及びＥ-ＵＴＲＡＮの両方にアクセス可能なＵＥに対して、ＡＶ（Ａｕｄｉｏ　Ｖｉｄｅｏ）通信を提供することが想定される。 In the mobile communication system described above, it is assumed that AV (Audio Video) communication is provided to a UE that can access both UTRAN / GERAN and E-UTRAN.
　ここで、Ｅ-ＵＴＲＡＮ配下のセルにおいて、ＩＭＳを介したＡＶ通信を提供することができない場合、Ｅ-ＵＴＲＡＮに在圏するＵＥに対しては、ＣＳＦＢ（ＣＳ　Ｆａｌｌｂａｃｋ）を用いて、ＵＴＲＡＮ/ＧＥＲＡＮにおいてＡＶ通信を提供する必要がある。 Here, in a cell under E-UTRAN, when AV communication via IMS cannot be provided, UTRAN / GERAN is used for UEs located in E-UTRAN using CSFB (CS Fallback). Need to provide AV communication.
　しかしながら、上述の移動通信システムでは、ＵＥ主導型の「Ｔ-ＡＤＳ」を用いて、ＵＥ宛てのＡＶ通信用の着信信号を転送すべきドメインを選択することができないという問題点があった。 However, the above-described mobile communication system has a problem in that it is not possible to select a domain to which an incoming signal for AV communication addressed to the UE should be transferred using UE-driven “T-ADS”.
　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、ＵＥ主導型の「Ｔ-ＡＤＳ」を用いて、ＵＥ宛ての音声通信用の着信信号についてだけでなく、ＵＥ宛てのＡＶ通信用の着信信号を転送すべきドメインを適切に選択することができる移動通信方法及び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 uses not only the incoming signal for voice communication addressed to the UE but also the AV communication addressed to the UE using the UE-driven “T-ADS”. It is an object of the present invention to provide a mobile communication method and a mobile station capable of appropriately selecting a domain to which an incoming call signal is to be transferred.
