Description

本発明は、ユーザ端末と無線基地局と移動体交換局と無線基地局制御装置とで構成される移動体通信ネットワークシステムに関し、特に、移動体交換局の障害時における緊急通話を考慮した、無線基地局制御装置によるスタンドアローン呼処理制御方式に係るものである。   The present invention relates to a mobile communication network system including a user terminal, a radio base station, a mobile switching center, and a radio base station control device, and more particularly, a wireless communication system considering an emergency call when a mobile switching center fails. The present invention relates to a stand-alone call processing control system by a base station controller.

移動体通信ネットワークシステムにおいて、ＣＮ（Core Network、移動体交換局）のシステムダウンや伝送路障害等が発生し、ＲＮＣ（Radio Network Controller 、無線基地局制御装置）との通信が不可能になった場合、ＲＮＣ、無線基地局、ユーザ端末それぞれが正常に稼動していても通話を実現することは出来ない。   In a mobile communication network system, CN (Core Network, mobile switching center) system down, transmission path failure, etc. occurred, and communication with RNC (Radio Network Controller, radio base station controller) became impossible. In this case, even if each of the RNC, the radio base station, and the user terminal is operating normally, a call cannot be realized.

例えば、災害発生により警察署あるいは消防署等の公共団体に対して連絡をとる必要がある場合、そのような公共団体の端末への通信だけでも確保することができれば、緊急的な通話を実現できる。   For example, when it is necessary to contact a public organization such as a police station or a fire department due to a disaster, an urgent call can be realized if communication can be secured only with the terminal of such a public organization.

特許文献１（特開平１１−２３４７３０号公報）には、緊急呼管理を行なう複数の無線端末並びに、単一の無線基地局及び無線基地局制御装置等からなるワイヤレス通信装置であって、各無線端末内の中央制御装置に少なくとも緊急呼番号判定手段と無線リンク確立手段を設け、また各無線端末内のメモリに少なくとも緊急呼番号蓄積メモリを設け、また無線基地局制御装置内の中央制御装置に少なくとも緊急呼要求制御手段、呼状態管理手段及び呼制御手段を設け、また無線基地局制御装置内のメモリに少なくとも呼状態管理メモリを設け、利用者が行なったダイヤル操作が緊急呼であるか否かを各無線端末の緊急呼番号判定手段で判定し、緊急呼であれば緊急呼識別情報を無線リンク確立手段が送出する無線リンク確立メッセージに付加して無線基地局に送出し、この緊急呼識別情報が付加された無線リンク確立メッセージを無線基地局経由で受け取った無線基地局制御装置の緊急呼要求制御手段は呼状態管理手段に問い合わて呼状態管理メモリからリンク接続状態を読み出し無線チャネルの空きの有無を判定し、もし空きがないならば、緊急呼要求制御手段は呼制御手段を起動して、既存の通話チャネル上の呼の切断・解放を行ない緊急呼用に無線チャネルを確保するように構成したワイヤレス通信装置が開示されている。   Patent Document 1 (Japanese Patent Application Laid-Open No. 11-234730) discloses a wireless communication device including a plurality of wireless terminals that perform emergency call management, a single wireless base station, a wireless base station control device, and the like, At least the emergency call number determination means and the radio link establishment means are provided in the central control device in the terminal, and at least the emergency call code storage memory is provided in the memory in each radio terminal, and the central control device in the radio base station control device. At least an emergency call request control means, a call state management means, and a call control means are provided, and at least a call state management memory is provided in the memory in the radio base station control device, so that the dial operation performed by the user is an emergency call. Is determined by the emergency call number determination means of each wireless terminal, and if it is an emergency call, emergency call identification information is added to the wireless link establishment message sent by the wireless link establishment means The emergency call request control means of the radio base station controller receives the radio link establishment message to which the emergency call identification information is added via the radio base station, and then calls the call state management means for calling. The link connection status is read from the state management memory to determine whether or not the radio channel is available. If there is no available channel, the emergency call request control unit activates the call control unit to disconnect / call the call on the existing call channel. A wireless communication device configured to release and reserve a radio channel for emergency calls is disclosed.

しかし、これは、警察署や消防署などを呼び出す緊急呼番号がダイヤルされたならば、空きチャネルが無くても現在確立中の呼を切断して緊急呼用に無線チャネルを確保し、緊急呼の優先的な通話路接続を実現するというものである。   However, if an emergency call number calling a police station or a fire station is dialed, even if there is no free channel, the currently established call is disconnected and a radio channel is secured for the emergency call. This is to realize preferential communication path connection.

また、特許文献２（特開２００４−２２９０９８号公報）には、無線制御装置（ＲＮＣ）に、第１の基地局を介して第１の移動局との間で第１の無線リンクを設定し、第２の基地局を介して第２の移動局との間で第２の無線リンクを設定するリンク設定部３と、第１又は第２の無線リンクに係る情報と第１又は第２の移動局のＩＰアドレスとをそれぞれ関連付けて記憶する記憶部と、第１の基地局から送信されたパケットに含まれる第２の移動局のＩＰアドレスに関連付けられている第２の無線リンクに係る情報を用いて当該パケットを第２の基地局に転送するパケット転送部とを具備した技術が開示されている。   Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2004-229098), a first wireless link is set up with a first mobile station via a first base station in a radio network controller (RNC). , A link setting unit 3 for setting a second radio link with the second mobile station via the second base station, information on the first or second radio link, and the first or second Information related to the second radio link associated with the IP address of the second mobile station included in the packet transmitted from the first base station, the storage unit storing the IP address of the mobile station in association with each other A technique including a packet transfer unit that transfers the packet to a second base station using a packet is disclosed.

しかし、これは、無線制御装置が、毎回コアネットワークを介して第２の移動局宛てのＩＰパケットを転送する必要がなくなることで、パケット転送効率の向上を図ったものである。
特開平１１−２３４７３０号公報 特開２００４−２２９０９８号公報 However, this eliminates the need for the wireless control device to transfer an IP packet addressed to the second mobile station via the core network every time, thereby improving packet transfer efficiency.

本発明の課題は、移動体交換局のシステムダウンや伝送路障害等が発生し、無線基地局制御装置との通信が不可能になった場合でも、例えば、災害発生により警察署あるいは消防署等の公共団体の端末に対して連絡をとる必要があるときには、このような特定の端末に対しては、端末が在圏しているエリアを管轄する無線基地局制御装置内での通信を確保することができるようにすることにある。   The problem of the present invention is that even when a mobile switching center system down or a transmission path failure occurs and communication with a radio base station control device becomes impossible, for example, a police station or a fire station or the like due to the occurrence of a disaster. When it is necessary to contact a terminal of a public organization, for such a specific terminal, ensure communication within the radio base station controller that has jurisdiction over the area where the terminal is located. Is to be able to.

本発明は、ユーザ端末と無線基地局と移動体交換局と無線基地局制御装置とで構成される移動通信システムにおいて、無線基地局制御装置に、特定の着信先端末情報を管理する端末情報管理部を備え、移動体交換局の障害時に、端末情報管理部の着信先端末情報によって当該着信先端末への接続処理を行い、当該着信先端末と発信元のユーザ端末との通信を無線基地局制御装置によって可能とすることを特徴とする。   The present invention relates to a mobile communication system composed of a user terminal, a radio base station, a mobile switching center, and a radio base station controller, and terminal information management for managing specific destination terminal information in the radio base station controller. And a connection process to the destination terminal based on the destination terminal information of the terminal information management unit when a failure occurs in the mobile switching center, and communication between the destination terminal and the source user terminal is performed by the radio base station It is made possible by a control device.

端末情報管理部を備えた複数の無線基地局制御装置同士が、相互の端末情報管理部の着信先端末情報を参照可能に接続され、当該着信先端末と発信元のユーザ端末との通信を複数の無線基地局制御装置によって可能とすることもできる。   A plurality of radio base station control devices provided with a terminal information management unit are connected so as to be able to refer to the destination terminal information of the mutual terminal information management unit, and a plurality of communications between the destination terminal and the source user terminal are performed. This can also be made possible by the radio base station controller.

無線基地局制御装置は、移動体交換局の通信が不可であることを無線基地局を介してユーザ端末に通知する。   The radio base station control device notifies the user terminal that the mobile switching center cannot communicate via the radio base station.

端末情報管理部は、着信先端末情報として、移動体加入者識別子、電話番号、ロケーションエリア情報を保持する。   The terminal information management unit holds a mobile subscriber identifier, a telephone number, and location area information as destination terminal information.

次に、本発明の参考例および実施形態を図面に基づいて詳細に説明する。 Next, reference examples and embodiments of the present invention will be described in detail with reference to the drawings.

［参考例］
図１に示すように、移動体通信ネットワークシステムは、移動体交換局（Core Network、以下「ＣＮ」と記す）１０と、無線基地局制御装置（Radio Network Controller、以下「ＲＮＣ」と記す）２０と、複数の無線基地局（以下「ＮｏｄｅＢ」と記す）３０・３１と、各無線基地局３０・３１に収容されるユーザ端末（User Equipment、以下「ＵＳ」と記す）４０・４１・４２とから構成される。ＬＡ０１およびＬＡ０２はロケーションエリア情報を示す。 [Reference example]
As shown in FIG. 1, a mobile communication network system includes a mobile switching center (Core Network, hereinafter referred to as “CN”) 10 and a radio base station controller (Radio Network Controller, hereinafter referred to as “RNC”) 20. A plurality of radio base stations (hereinafter referred to as “NodeB”) 30 and 31, and user terminals (User Equipment; hereinafter referred to as “US”) 40, 41, and 42 accommodated in each of the radio base stations 30 and 31, Consists of LA01 and LA02 indicate location area information.

本発明による移動体通信ネットワークシステムは、ＣＮ（１０）のシステムダウン、あるいはそのインタフェース５０の障害により、ＣＮ−ＲＮＣ間の通信が行えなくなった場合においても、ＵＴＲＡＮ（Universal Terrestrial Radio Access Network）内にて、予め局番号や機器固有情報等が登録されている端末への局所的な通話を可能とするため、ＲＮＣ（２０）に端末情報管理部２０’を具備している。   The mobile communication network system according to the present invention is included in the UTRAN (Universal Terrestrial Radio Access Network) even when communication between the CN and the RNC cannot be performed due to the system down of the CN (10) or the failure of the interface 50. The RNC (20) is provided with a terminal information management unit 20 ′ in order to make a local call to a terminal in which a station number, device specific information, etc. are registered in advance.

この端末情報管理部２０’には、ＣＮ（１０）との通信不可状態においても着信を許可させたい特定の着信先端末に関する着信先端末情報として、図２に示すように、移動体加入者識別子(International Mobile Subscriber Identity、以下「ＩＭＳＩ」と記す)や電話番号やロケーションエリア情報のリストが、システム構築時に予め登録されている。さらに、書き換え可能データとして、回線交換通話中であるかどうかの状態を示すフラグも保持される。   As shown in FIG. 2, the terminal information management unit 20 ′ includes a mobile subscriber identifier as destination terminal information regarding a specific destination terminal that is desired to be allowed to receive calls even when communication with the CN (10) is disabled. (International Mobile Subscriber Identity, hereinafter referred to as “IMSI”), a list of telephone numbers and location area information are registered in advance at the time of system construction. Furthermore, a flag indicating whether or not a circuit-switched call is in progress is held as rewritable data.

図１において、ＣＮ（１０）のシステムダウン、あるいはインタフェース５０の障害を認識したＲＮＣ（２０）は、配下のＮｏｄｅＢ（３０・３１）に対し、ＣＮ通信不可状態であることを通知する。第一のＵＥ（４０）はＣＮ通信不可状態であることを認識すると、通常の位置情報登録手順をスキップして発呼処理を実施し、ＲＮＣ（２０）は着信先である第二のＵＥ４１の端末情報を、端末情報管理部２０’よりサーチする。サーチに成功すれば、ＣＮ（１０）とのやり取りを全く必要とせずにＲＮＣ（２０）で着信処理を実施することで通話を実現する。   In FIG. 1, the RNC (20) that has recognized the CN (10) system down or the interface 50 failure notifies the subordinate NodeBs (30 and 31) that the CN communication is disabled. When the first UE (40) recognizes that the CN communication is disabled, the normal location information registration procedure is skipped and the calling process is performed, and the RNC (20) is the destination UE of the second UE 41. The terminal information is searched from the terminal information management unit 20 ′. If the search is successful, the RNC (20) performs the incoming call processing without requiring any communication with the CN (10), thereby realizing a call.

すなわち、ＣＮ通信不可状態を認識したＵＥは位置情報登録をスキップして発呼処理を実施し、ＲＮＣ（２０）内で端末の認証、特定の着信先端末情報の取得、ページング処理、そして着信処理をＣＮ（１０）に代わり制御することで、当該特定の着信先端末への通話を実現する。端末情報管理部２０’に着信先端末情報が登録されていない端末への着信は接続不可とする。   That is, the UE that has recognized the CN communication disabled state skips location information registration and performs call processing, and performs terminal authentication, acquisition of specific destination terminal information, paging processing, and incoming call processing within the RNC (20). Is controlled in place of CN (10), thereby realizing a call to the specific destination terminal. An incoming call to a terminal whose destination terminal information is not registered in the terminal information management unit 20 'is not connectable.

次に、このような動作ついて図３及び図４に示すシーケンスチャートを用いて詳説する
。
まず、ＣＮとの通信不可状態をＵＥが認識するまでの手順を図３で説明する。
＜１＞ＲＮＣがＣＮとの通信不可状態を検出すると、ＲＮＣは配下のＮｏｄｅＢに対してＮＢＡＰ: System Information Update手順(TS 25.433)を用い、新規報知情報としてＣＮとの通信不可状態であることを通知する。
＜２＞通知を受けたＮｏｄｅＢは配下のＵＥに対して、ＣＮとの通信不可状態を通知し、ＵＥは報知チャネルを通じて状態を認識する。 Next, such an operation will be described in detail with reference to the sequence charts shown in FIGS.
First, a procedure until the UE recognizes a state incapable of communicating with the CN will be described with reference to FIG.
<1> When the RNC detects that the CN cannot communicate with the CN, the RNC uses the NBAP: System Information Update procedure (TS 25.433) for the subordinate NodeB and confirms that the communication with the CN is not possible as new notification information. Notice.
<2> The NodeB that has received the notification notifies the subordinate UE of the communication disabled state with the CN, and the UE recognizes the state through the broadcast channel.

その後の通話処理手順を図４で説明する。
＜１＞上記手順にてＣＮ通信不可状態を認識したＵＥは、従来の位置登録手順を実施せずに、新規手順としてＲＮＣへ発呼要求（図４の（ａ））を送信する。本要求は発信元および発信先端末の情報を含む。
＜２＞ＣＮに代わりＲＮＣが、発信元端末の認証処理を実施する（図４の（ｂ））。
＜３＞発呼要求に搭載されている発信先端末の電話番号をキーにして、端末情報管理部２０’に発信先端末のエントリがあるかサーチする（図４の（ｃ））。 The subsequent call processing procedure will be described with reference to FIG.
<1> The UE that has recognized the CN communication disabled state in the above procedure transmits a call request ((a) in FIG. 4) to the RNC as a new procedure without performing the conventional location registration procedure. This request includes information on the source and destination terminals.
<2> In place of CN, the RNC performs authentication processing of the caller terminal ((b) in FIG. 4).
<3> Using the telephone number of the destination terminal loaded in the call request as a key, the terminal information management unit 20 ′ searches for an entry of the destination terminal ((c) in FIG. 4).

＜４−１＞エントリがある場合、かつ該当エントリの回線交換通話中フラグを参照し、通話中でなければ＜５＞の処理へ。
＜４−２＞エントリがない、あるいは該当エントリの回線交換通話中フラグが通話中状態を示していれば、ＵＥに発呼ＮＧを返送して手順を終了する。 <4-1> If there is an entry and the circuit-switched call flag of the entry is referred to, if not busy, proceed to <5>.
<4-2> If there is no entry or the circuit-switched call flag of the corresponding entry indicates a busy state, the call NG is returned to the UE and the procedure is terminated.

＜５＞端末情報管理部２０’より取得した発信先ＵＥのＩＭＳＩ情報およびロケーション
情報を用いて、ロケーションエリアに対してＲＲＣ: Paging手順(TS 25.331)にてページ
ングを実施する（図４の（ｄ））。
＜６＞ＣＮに代わりＲＮＣが、発信先端末の認証処理を実施する（図４の（ｅ））。
＜７＞ＲＮＣが主導となり、送信元／発信先ＵＥとＮｏｄｅＢ−ＲＮＣ間において無線アクセスベアラの確立処理を実施する（図４の（ｆ））。
＜８＞ALARTING、およびCONNECT/CONNECT ACK手順をＣＮに代わりＲＮＣが制御することで、通話を実現する（図４の（ｇ））。
＜９＞端末情報管理部における発信先端末のエントリ、回線交換通話中フラグを「通話中」に設定する（図４の（ｈ））。 <5> Using the IMSI information and location information of the destination UE acquired from the terminal information management unit 20 ′, paging is performed on the location area using the RRC: Paging procedure (TS 25.331) ((d in FIG. 4). )).
<6> Instead of CN, the RNC performs authentication processing of the destination terminal ((e) in FIG. 4).
<7> The RNC takes the lead, and establishes a radio access bearer between the source / destination UE and the NodeB-RNC ((f) in FIG. 4).
<8> The RNC controls the ALARTING and CONNECT / CONNECT ACK procedures instead of the CN, thereby realizing a call ((g) in FIG. 4).
<9> The entry of the destination terminal in the terminal information management unit and the line exchange call busy flag are set to “busy” ((h) in FIG. 4).

これにより、ＣＮ−ＲＮＣ間の通信が行えない状況下においても、端末が在圏しているエリアを管轄するＲＮＣ内での通話を確保することができ、例えば、警察署あるいは消防署等の公共団体に対する緊急的な連絡等が可能となる。   As a result, even in a situation where communication between the CN and the RNC cannot be performed, it is possible to secure a call within the RNC that has jurisdiction over the area where the terminal is located. For example, a public organization such as a police station or fire station Urgent contact etc. is possible.

上記公共団体における端末は、それらの施設内にて使用されることを前提にすれば、予め端末のロケーション情報を認知することが可能であり、それら端末情報をＲＮＣで予め保持させておくことにより、ＵＴＲＡＮ（Universal Terrestrial Radio Access Network）内での呼処理を実現できる。   Assuming that terminals in the above public organizations are used in those facilities, it is possible to recognize the location information of the terminals in advance, and by holding these terminal information in advance in the RNC , Call processing within the UTRAN (Universal Terrestrial Radio Access Network) can be realized.

［実施の形態］
本発明の実施の形態は、その基本的構成は上述した参考例と同様であるが、ＲＮＣを複数として、これらの間のインタフェースをしたもので、その構成を図５に示す。同図に示すように、複数のＲＮＣ（２０・２１）がインタフェース５１にて接続され、これらＲＮＣ（２０・２１）のそれぞれに端末情報管理部２０’・２１’が備わっている。ＬＡ０１およびＬＡ０３はロケーション情報を表している。 [Embodiment]
The basic configuration of the embodiment of the present invention is the same as that of the reference example described above. However, a plurality of RNCs are used as interfaces, and the configuration is shown in FIG. As shown in the figure, a plurality of RNCs (20, 21) are connected by an interface 51, and each of these RNCs (20, 21) is provided with a terminal information management unit 20 ′, 21 ′. LA01 and LA03 represent location information.

本実施の形態において、参考例と同様に発信先端末のエントリを端末情報管理部２０’よりサーチする際、もしこの端末情報管理部２０’にエントリが見つからない場合は、インタフェース５１を経由した先のＲＮＣ（２１）の端末情報管理部２１’のエントリのサーチを実施する。このようにインタフェース５１を介したＤｒｉｆｔ−ＲＮＣを考慮することで、さらに広範囲かつ多くの端末との、ＵＴＲＡＮ内通話が可能となる。 In this embodiment, as in the reference example , when searching for an entry of a destination terminal from the terminal information management unit 20 ′, if no entry is found in the terminal information management unit 20 ′, the destination via the interface 51 is searched. The search of the entry of the terminal information management unit 21 ′ of the RNC (21) is performed. In this way, by considering the Drift-RNC via the interface 51, it is possible to make UTRAN calls with a wider range of terminals.
