- the storage unit 303 stores the cell ID of the cell of the HNB (# 2) 200-2 as the cell ID of the cell in which the UE 100 is located during the UE Registration process of Step B2. Therefore, the control unit 302 includes the cell ID of the cell of the HNB (# 2) 200-2 in the Position Activation Response message that is a response message to the Position Activation Request message in Step B7 (Step B8). Then, the control unit 302 transmits a Position Activation Response message to the SAS 400 via the communication unit 301 (step B9).
- the subsequent operation differs depending on whether or not the location information of the UE 100 is periodically reported in the Location Reporting Control message in Step B4.

- the MSC 500 or the SGSN 600 when the MSC 500 or the SGSN 600 receives the Location Report message from the HNB-GW 300, the MSC 500 or the SGSN 600 transmits the location information of the UE 100 included in the Location Report message to the external LCS client 800 via the GMLC 700.
- the location reporting control message in step B4 indicates that the UE 100 location information is not periodically reported (that is, the UE 100 location information is reported only once). did.
- the sequence in the case of periodically reporting the location information of UE 100 corresponds to a sequence in which steps C1 to C10 are added between steps B9 and B10 in FIG. Therefore, first, similarly to FIG. 6, the processes of steps B1 to B9 are performed.
- the SAS 400 When the Position Activation Response message is received from the HNB-GW 300, the SAS 400 generates a Position Periodic Result message for notifying the periodic result of the location information of the UE 100, as in Step B10 of FIG. Specifically, the SAS 400 includes, in the Position Periodic Result message, information related to the cell range of the cell of the HNB (# 2) 200-2 as the location information of the UE 100. Then, the SAS 400 transmits the Position Periodic Result message to the HNB-GW 300 (step C1).
- the control unit 302 when the Position Periodic Result message is received by the communication unit 301 from the SAS 400, the control unit 302 generates a Location Report message for reporting the location information of the UE 100, substantially in the same manner as Step B11 in FIG. (Step C2). Specifically, the control unit 302 extracts the location information of the UE 100 included in the Position Periodic Result message, and includes the extracted location information of the UE 100 in the Location Report message. Then, the control unit 302 transmits the Location Report message from the communication unit 301 to the MSC 500 or SGSN 600 (step C3).
- steps C4 to C9 similar to steps B7 to B9 and C1 to C3 is performed, and a second Location Report message is transmitted from the HNB-GW 300 to the MSC 500 or SGSN 600.
- the MSC 500 or SGSN 600 reports the location information of the UE 100 included in the Location Report message to the external LCS client 800 via the GMLC 700.
- the SAS 400 has already periodically notified the location information of the UE 100 using the Position Periodic Result message. Therefore, the position information of the UE 100 may not be included in the Position Initiation Response message in Step B10 of FIG.
- the HNB-GW 300 when receiving the location information request of the UE 100 from the MSC 500 or the SGSN 600, the HNB-GW 300 terminates the location information request without transferring it to the HNB 200. Then, the HNB-GW 300 transmits the cell ID of the cell where the UE 100 is located to the SAS 400 as information necessary for generating the location information of the UE 100. When the information related to the cell range of the cell in which UE 100 is located is returned from SAS 400 as the location information of UE 100, HNB-GW 300 returns the location information of UE 100 to MSC 500 or SGSN 600.
- the HNB-GW 300 itself that has received the UE 100 location information request provides the SAS 400 with the cell ID of the cell in which the UE 100 is located as information necessary for generating the UE 100 location information.
- the position information of the UE 100 is generated. Therefore, in generating the location information of the UE 100, the HNB 200 of the cell in which the UE 100 is located does not exchange information with the SAS 400, and thus does not need to support LCS. Therefore, even when the HNB 200 deployed in the market does not support LCS, the location information of the UE 100 located in the cell of the HNB 200 can be generated.
- HNBs that will be marketed in the future for the realization of LCS need not be implemented with the PCAP protocol and PUA protocol in order to support LCS, thereby preventing an increase in price.
- location information is used, but all or a part of “location information” may be read as “location information”.
- location information it is conceivable to replace “location information” with “location information” exchanged between the HNB-GW 300 and the MSC 500 or SGSN 600, between the MSC 500 or SGSN 600 and the GMLC 700, and between the GMLC 700 and the external LCS client 800.

Abstract
Description
・3GPP Release12で定義された方式のLCSをサポートしていないHNBは市場に多数展開済みであり、市場に展開済みのHNBに上記Release12で定義された方式のLCSをサポートさせることは難しい。そのため、このようなHNBのセルに在圏する端末については位置情報を生成することができない。
・今後市場に展開するHNBにPCAPプロトコル及びPUAプロトコルを実装すると、HNBの価格が高くなってしまう。
(1)実施形態1
図1に、本実施形態の無線通信システムの構成例を示す。図1を参照すると、本実施形態の無線通信システムは、端末10と、基地局(#1~#3)20-1~20-3と、ゲートウェイ装置30と、位置情報生成装置40と、コアネットワーク装置50と、を備えている。なお、図1においては、ゲートウェイ装置30の配下に3つの基地局(#1~#3)20-1~20-3を設けた例を示しているが、ゲートウェイ装置30の配下に設ける基地局の数は3つには限定されず、複数であれば良い。また、以下では、基地局(#1~#3)20-1~20-3を特定しない場合は、基地局20と記述する場合がある。
基地局(#1~#3)20-1~20-3は、自身のセルに在圏する端末10と無線通信を行う基地局であり、例えば、HNBである。図1においては、基地局(#2)20-2のセルに端末10が在圏している。
位置情報生成装置40は、端末10の位置情報を生成する役割を持つノードであり、例えば、SASである。
ゲートウェイ装置30は、コアネットワーク装置50から端末10の位置情報要求を受信した場合、その位置情報要求を基地局20に転送することなく終端し、端末10の位置情報の生成に必要な情報を位置情報生成装置40に送信する。
そこで、ゲートウェイ装置30は、位置情報生成装置40に対し、端末10の位置情報の生成に必要な情報として、例えば、端末10が在圏するセル又はそのセルを形成する基地局20を特定する情報を送信することができる。
なお、図1に示される、ゲートウェイ装置30以外の構成要素については、関連技術の構成で実現可能であるため、詳細な説明は省略する。
図3を参照すると、コアネットワーク装置50は、端末10の位置情報要求をゲートウェイ装置30に送信する(ステップA1)。
本実施形態は、実施形態1の無線通信システムを3Gの無線通信システムに適用した例である。図4に、本実施形態の無線通信システムの構成例を示す。図4を参照すると、本実施形態の無線通信システムは、UE(User Equipment)100と、HNB(#1~#3)200-1~200-3と、HNB-GW300と、SAS400と、MSC(Mobile services Switching Center)500と、SGSN(Serving GPRS Support Node、GPRS:General Packet Radio Service)600と、GMLC(Gateway Mobile Location Center)700と、外部LCSクライアント(External LCS Client)800と、を備えている。なお、図4においては、3つのHNB(#1~#3)200-1~200-3及びHNB-GW300によりフェムトシステムを構成する例を示しているが、フェムトシステムを構成するHNBの数は3つには限定されず、複数であれば良い。また、以下では、HNB(#1~#3)200-1~200-3を特定しない場合は、HNB200と記述する場合がある。
HNB(#1~#3)200-1~200-3は、自身のセルに在圏するUE100と無線通信を行う基地局である。図4においては、HNB(#2)200-2のセルにUE100が在圏している。
SAS400は、UE100の位置情報を生成する役割を持つノードであり、位置情報生成装置の一例である。
GMLC700は、外部LCSクライアント800からUE100の位置情報要求を受け付けるノードである。GMLC700は、外部LCSクライアント800からUE100の位置情報要求を受信すると、UE100の位置情報要求をMSC500又はSGSN600に送信する。
SGSN600は、コアネットワークに配置され、MSC500と同様にUE100のモビリティ制御を行うと共に、PS(Packet Switched)呼の制御を行うノードであり、コアネットワーク装置の一例である。
MSC500及びSGSN600は、GMLC700からUE100の位置情報要求を受信すると、UE100の位置情報要求をHNB-GW300に送信する。
なお、図4に示される、HNB-GW300以外の構成要素については、関連技術の構成で実現可能であるため、詳細な説明は省略する。
HNB-GW300においては、MSC500又はSGSN600から、Location Reporting Controlメッセージを通信部301にて受信すると、制御部302は、そのLocation Reporting Controlメッセージに含まれている情報を記憶部303に記憶させる。ここで、記憶部303は、ステップB3のNAS Procedure処理の際に、UE100とMSC500及びSGSN600との間に確立されたコネクションに関する情報を記憶している。そのため、制御部302は、Location Reporting Controlメッセージの送信に使用されたコネクションを基に、UE100を特定することができる。続いて、制御部302は、UE100の位置情報を要求するPosition Initiation Requestメッセージを生成する(ステップB5)。具体的には、制御部302は、Position Initiation Requestメッセージには、Location Reporting Controlメッセージに従い、UE100の位置情報を周期的に報告するか否かを指示する情報等を含める。そして、制御部302は、通信部301を介してSAS400に対し、Position Initiation Requestメッセージを送信する(ステップB6)。

そのため、SAS400は、上記7つの形式のうち、いずれか1つの形式で表現されるセルの位置に関する情報を、UE100の位置情報としてメッセージに含めて、HNB-GW300に送信する。HNB-GW300は、SAS400から受信したUE100の位置情報を、形式変換することなく、そのままメッセージに含めて、MSC500又はSGSN600に送信する。
