  In FIG. 2, HNB220 is called a femto base station, and shows a small radio base station corresponding to the third generation radio system (W-CDMA). An HNB-GW (3G HNB Gateway) 210 is a gateway device that aggregates a large number of HNBs 220 and connects to a core network (hereinafter referred to as CN: 240) 240 serving as a host device or an external network. That is, the HNB-GW 210 is a gateway for a femto base station that relays a plurality of femto base stations to the CN 240. UE (User equipment) 230 shows the portable terminal which is a mobile station which a user owns. An MGW (Media Gateway) 214 is a media gateway device that can acquire media information by connecting to a network and includes a codec / media conversion function having an announcement function. The plurality of HNBs 220 are connected to the HNB-GW 210 and communicate with the CN 240 via the HNB-GW 210. In the present embodiment, an MGW 214 is arranged inside the HNB-GW 210. Note that the MGW 214 may be configured to operate independently within the HNB-GW 210, or may be incorporated into the HNB-GW 210 as one function.

(Functional configuration of HNB-GW of the second embodiment)
A functional configuration of the HNB-GW 210 including the MGW function shown in FIG. 2 will be described.

  As shown in FIG. 2, the HNB-GW 210 is an HNBAP (Home Node B Application Part), RANAP (Radio Access Network Application Part) or RUA (RANAP User Adaption) protocol with other devices (UE, HNB, etc.). The communication control unit 211 performs transmission / reception of these signals. Further, when receiving a call from the UE 230, the HNB discriminating unit 212 that discriminates through which HNB 220 the call is received and whether the HNB 220 is an HNB to be announced. In addition, it has an announcement designation unit 213 that selects an announcement corresponding to the HNB 220 identified by the HNB discrimination unit 212 and designates it to the MGW 214. In addition, it has an MGW 214 including an announcement unit 215 that sends an announcement designated by the announcement designation unit 213 to the UE 230 that has made a call via the HNB 220 identified by the HNB discrimination unit 212. The MGW 214 has a function of performing IP⇔ATM (Internet Protocol⇔Asynchronous Transfer Mode) conversion and path control of voice data.

<Operation Sequence of Communication System of Second Embodiment>
FIG. 3 is a sequence diagram showing a processing procedure 300 of the communication system according to the second embodiment. In the present embodiment, prior to connection of a voice call from the HNB 220 installed at a specific location registered in the HNB-GW 210 in advance, alerts or advertisements depending on the installation location of the HNB 220 are provided before communication for the call is started. It is possible to announce.

  In the database of the HNB-GW 210 (hereinafter referred to as DB), information on what announcements are connected to the announcement target HNB 220 is registered in advance. When the UE 230 makes a voice call via the HNB 220, a SETUP message is sent to the CN 240 (S301), and CALL PROCESSING is started (S303). Among them, establishment of a radio bearer (RB) for confirming the performance of the UE 230 that has made a voice call is performed by the following protocol. First, a RAB (Radio Access Bearer) Assignment Req. Message is sent from the CN 240 to the HNB 220 via the HNB-GW 210 (S305). An exchange of an RB Setup Req. Message and an RB Setup Resp. Message is performed between the HNB 220 and the UE 230 (S307). In response to the RB Setup Resp. Message, the HNB 220 returns a RAB Assignment Resp. Message to the HNB-GW 210. Here, Req. Is an abbreviation for Request, and Resp. Is an abbreviation for Response.

  The HNB-GW 210 performs the announcement process of this embodiment without relaying it immediately to the CN 240 even if it receives the response of the RAB Assignment Resp. Message. First, the HNB-GW 210 identifies the HNB 220 that has passed the voice call from the UE 230, and determines whether the identified HNB 220 is the HNB 220 to be announced based on the information in the database (S311). The HNBiD for identifying the HNB 220 can be known from the SETUP message (S301). If the HNB 220 is not the announcement target, the HNB-GW 210 proceeds to a normal call connection process (S313).

  If it is the HNB 220 to be announced, the announcement data corresponding to the HNB 220 is designated from the data in the database (S315). Next, the HNB-GW 210 uses No. 8 (in-band information or appropriate pattern is now available) indicating the announcement connection in the progress indicator of the PROGRESS message of the CC (Call Control) protocol defined in 3GPP TS24.008. Is transmitted to the UE 230 (S317). After that, the HNB-GW 210 is used for voice encoding allowed by the UE 230 from the setting of NAS (Non Access Stratum) Synchronization Indicator IE (Information Element) included in the RANAP: RAB Assignment Req. Message received when the radio bearer is established. The Codec is discriminated (S319). Then, after appropriate codec conversion is performed in the MGW 214 (S321), the corresponding announcement set in the database is connected to the UE 230 (S323).

  When the CC: ALERTING message including the call tone of the callee is received before the announcement is finished (S327), the HNB-GW 210 queues and waits until the announcement is finished (S329). And it transmits to UE230 after the end of announcement (S331), and the connection process of a voice call is continued. On the other hand, if the CC: CONNECT message indicating the connection by off-hook of the communication destination is received before the announcement is completed (S333), the announcement is stopped, the path is switched to the CN 240 side, the voice call is connected, and the call is established. (S335).

<HNB-GW Hardware Configuration of Second Embodiment>
FIG. 4 is a block diagram illustrating a hardware configuration of the HNB-GW 210 that is a communication control apparatus according to the second embodiment.

The ROM 420 stores fixed data and programs such as initial data and programs. The communication control unit 211 communicates with the HNB 220 and the CN 240 via a network. Communication may be wireless or wired.

  The RAM 440 is a random access memory that the CPU 410 uses as a work area for temporary storage. In the RAM 440, an area for storing data necessary for realizing the present embodiment is secured. Each area stores an HNBiD 441 that identifies the HNB 220 through which the calling UE 230 has passed. Also, announcement data 442 transmitted to the calling UE 230 is stored. The HNBiD 441 and the announcement data 442 are stored as many as the number of HNBs that are being processed by the HNB-GW 210.

  The RAM 440 stores a UEiD that identifies the calling UE 230 and an announcement flag 443 that indicates whether or not the announcement is in progress. In addition, a parameter 444 of RAB Assignment Req. Is stored in order to determine the codec to be used. Also, the determined CodeciD 445 is stored. In addition, ALERTING information 446 of the ALERTING message sent from the CN 240 and CONNECT information 447 of the COONECT message are stored for transfer to the UE 230. Although not shown in detail in FIG. 4, the data of 443 to 447 is stored in association with each HNB by the number of UEs for which the HNB-GW 210 is in the process of connection.

  The storage 450 is a mass storage device that stores a database, various parameters, and a program executed by the CPU 410 in a nonvolatile manner. The storage 450 stores the following data or programs necessary for realizing the present embodiment. As data, an HNB table 451 including a flag indicating whether the HNB is an announcement target and a pointer indicating the announcement information is stored in association with the HNB 220.

In the present embodiment, an HNB-GW control program 453 (see FIGS. 6A to 6C) indicating the control procedure of the entire HNB-GW 210 and an MGW control module 454 for controlling the MGW 214 are stored as programs.

  Note that FIG. 4 shows only data and programs essential to the present embodiment, and general-purpose data and programs such as OS are not shown.

<Configuration of data used by HNB-GW>
The characteristic data structure used in the second embodiment will be described below. FIG. 5 is a diagram illustrating a configuration of data used by the HNB-GW according to the second embodiment.

(Configuration of HNB table)
The left figure of FIG. 5 shows the structure of the HNB table 451 of 2nd Embodiment. A flag (YES / NO) 552 indicating whether or not an announcement is made in association with HNBiD 551 which is an identifier for identifying HNB 220 via a call from UE 230, and a pointer 553 to information to be announced in announcement DB 452 Is memorized.

(Structure of announcement DB)
The right diagram in FIG. 5 shows the configuration of the announcement DB 452. Announcement data A (554) and announcement data B (554) are stored at positions indicated by the pointer 553 of the HNB table 451.

  In FIG. 5, HNBs with HNBiD551 “001” and “003” are announcement targets, and announcement data A and B are respectively announced.

<Operation Procedure of HNB-GW of Second Embodiment>
6A to 6C are flowcharts showing the processing procedure of the HNB-GW according to the second embodiment. This flowchart is executed by the CPU 410 while using the RAM 440, and each functional component of the HNB-GW 210 of FIG. 2 is realized.

  First, in steps S601, S603, and S615 of FIG. 6A, it is determined whether an event that has occurred in the HNB-GW 210 is due to reception from the HNB 220 or the UE 230, reception from the CN 240, or termination of the announcement. .

  If it is a call from UE230 via HNB220, it will progress to step S601 from S601, and it will be judged whether it is a SETUP message. If it is a SETUP message, the SETUP message is transferred to the CN 240 in step S611. In step S613, the HNBiD of the HNB 220 that has made the call is acquired and stored. If the response is a CONNECT ACK response from the UE 230 via the HNB 220, the process advances from step S607 to S615 to transfer the CONNECT ACK to the CN 240 and establish a call with the callee. If the RAB Assignment Resp. Is based on the RB Setup Resp. By the UE 230 from the HNB 220, the process proceeds to step S617 in FIG. 6B. If the reception from the HNB 220 or the UE 230 is neither of the above, other processing is performed.

  In step S617 of FIG. 6B, it is determined whether or not this HNB is an announcement target with reference to the HNB table 451 from the acquired HNBiD. If it is not an announcement target (for example, refer to the HNB of HNBiD “002” in FIG. 5), the process proceeds to a normal call connection process. Specifically, the HNB-GW 210 transfers RAB Assignment Resp. To the CN 240 without any announcement. Next, in step S619, the progress indicator No. 8 indicating the announcement connection in the PROGRESS message is turned ON, and the UE 230 that made the call is notified of the start of the announcement. Subsequently, in step S621, the Codec to be used is specified from the RAB Assignment Req. Parameter received from the CN 240 in steps S631 to S637 described later. In step S623, the announcement data is read from the HNBiD with reference to the HNB table 451, and the announcement is started to the UE 230 that has made the call with the codec specified in step S621. At the same time, in step S623, the announcement flag 443 is turned ON. In addition, it is preferable that the announcement part 215 of MGW214 inside HNB-GW210 performs an announcement process uniquely. When the announcement starts, in step S625, RAB Assignment Resp. Held in the HNB-GW 210 is transferred to the CN 240 in order to continue the call processing.

  Returning to FIG. 6A, if the event occurring in the HNB-GW 210 is due to reception from the CN 240, the process proceeds from step S603 to step S633 in FIG. 6C. In step S633 of FIG. 6C, it is determined whether or not the message is a RAB Assignment Req. Message from CN 240. If it is a RAB Assignment Req. Message, the process proceeds to step S639, and the RAB Assignment Req. Message is transferred to the HNB 220 via a call from the UE 230. At the same time, the parameter of the RAB Assignment Req. Message is retained for use in step S621. If the message from the CN 240 is ALERTING, the process proceeds from step S635 to S641, and it is determined by the announcing flag 443 whether or not the calling UE 230 is currently being announced. If it is determined that the announcement is in progress, the process proceeds to step S643, and the ALERTING message is queued in the HNB-GW 210 without being sent to the UE 230. On the other hand, if it is determined that the announcement is not in progress, the process proceeds to step S645, and the ALERTING message is transferred to the UE 230. If the message from the CN 240 is CONNECT, the process proceeds from step S637 to S647, the announcement is immediately stopped, and the announcement flag 443 is turned OFF. Next, the CONNECT message is transferred to the UE 230 that originated the call.

  Returning to FIG. 6A, when the announcement being executed is terminated, the process proceeds from step S615 to step S627 in FIG. 6B. In step S627 of FIG. 6B, the announcement flag 443 of the target UE 230 is turned OFF. In step S629, it is determined whether or not ALERTING queuing in step S643 of FIG. 6C is performed. If it is queued, it will progress to step S631 and will transfer the suspending ALERTING message to object UE230. If it is not queued, the process is terminated, and ALERTING or CONNECT from CN 240 is awaited.

[Third Embodiment]
Next, the communication system of 3rd Embodiment of this invention is demonstrated. In the second embodiment, whether or not to announce corresponding to the HNB and the contents of the announcement are set in advance. Accordingly, the present invention can be applied to an announcement such as “Please turn off the mobile phone” at an HNB fixed in a hospital or the like. However, if the HNB is movable and the installation location is freely changed, it takes time to set whether or not to announce each time. In the present embodiment, the current position of the HNB is determined, whether or not an announcement is necessary at the current position, and the content of the announcement when necessary is determined by the HNB-GW, and an announcement before starting communication by calling is made. Do. According to the present embodiment, even when the installation location of the HNB is changed, an announcement before starting communication by calling can be realized.

In step S617 of FIG. 14, it is determined whether or not this HNB is an announcement target with reference to the HNB table 451 from the acquired HNBiD. If it is not an announcement target, the process proceeds to a normal call connection process. Specifically, the HNB-GW 1210 transfers RAB Assignment Resp. To the CN 240 without an announcement. Next, in step S619, the progress indicator No. 8 indicating the announcement connection in the PROGRESS message is turned ON, and the UE 230 that made the call is notified of the start of the announcement. Subsequently, in step S621, the Codec to be used is specified from the RAB Assignment Req. Parameter received from the CN 240. In the present embodiment, in step S1423, the HNB iD refers to the HNB table 451 and instructs the MGW 1250 to specify the storage location of the announcement data and the codec to be used. At the same time, the announcement flag 443 is turned ON in step S1423. Note that the announcement process may be performed directly by the announcement unit 1251 of the MGW 1250 with the UE 230 without the control of the HNB-GW 1210. When the announcement starts, in step S625, the RAB Assignment Resp. Held in the HNB-GW 210 to start the announcement is transferred to the CN 240 during steps S609 to S623.

[Fifth Embodiment]
Next, a communication system according to a fifth embodiment of this invention will be described. In the above embodiment, whether or not to announce corresponding to only HNB and the contents of the announcement have been determined. Therefore, the announcement is made to all the mobile terminals that have entered the cell range of the HNB that makes the announcement. Therefore, the UE or the user who does not need to make an announcement is also announced, and the contents that should be announced once have to be heard for each call. In this embodiment, even if it is determined that the HNB or its position is announced, the UE or the user can control the UE or the user who does not need the announcement so that the announcement is not made. According to this embodiment, even when the HNB is arranged at a position where an announcement is required, it is possible to control whether or not to make an announcement before starting communication by calling for each UE or user. For example, using a CSG (Closed Subscriber Group) or a phone number to make a specific UE subject to connection / untargeted announcements, or from a past connection history, a UE that has already connected to the announcement does not connect to the announcement Such control can also be implemented.

The MGW 2014 has a function of performing audio data path control.

<Operation Sequence of Communication System of Sixth Embodiment>
FIG. 21 is a sequence diagram showing a processing procedure 2100 of the communication system according to the sixth embodiment.
In the database of the HeNB-GW 2010, for example, as shown in FIG. 5 of the second embodiment, information on what announcements are connected to the announcement target HeNB 2020 is registered in advance. When the UE 230 sends a voice call via the HeNB 2020, an INVITE message is sent to the CN 240 (S2101), and a sequence for call establishment is executed as Offer Response → Response Confirmation → Confirmation Acknowledge → Reservation Conf. (S2103 to S2111). Is done. Reservation Conf. Is an abbreviation for Reservation Confirmation.

The HeNB-GW 2010 that has received the Reservation Conf. (S2111) from the CN 240 first identifies the HeNB 2020 via the voice call from the UE 230, and determines whether the identified HeNB 2020 is the announcement target HeNB 2020 based on the database information. (S2113). The HNBiD for identifying the HeNB 2020 can be known from the INVITE message (S2101). If the HeNB 2020 is not the announcement target, the HeNB-GW 2010 proceeds to a normal call connection process (S2115).
If it is HeNB2020 of announcement object, the announcement data corresponding to HeNB2020 will be designated from the data of a database (S2117). Next, the HeNB-GW 2010 discriminates the Codec used for voice encoding allowed by the UE 230 from the SIP message (S2103 to S2111) exchanged at the time of call establishment (S2119), and transmits the SIP200_OK message to the UE (S2121). . And after performing appropriate Codec conversion in MGW2014 (S2123), the announcement set to a database is connected to UE230 (S2125).

  If a Ringing message is received before the announcement is finished (S2127), the Ringing message is discarded. When the SIP 200_OK message indicating connection completion is received (S2129), the announcement is stopped, the path is switched to the CN 240 side (S2131), the voice call is connected, and the call is established (S2133).

  Hereinafter, other configurations and operation procedures of the sixth embodiment can be inferred from the second embodiment, and thus illustration and description thereof are omitted.

An MGW 2250 indicates a gateway apparatus including a codec / media conversion function having an announcement function. The plurality of HNBs 220 are connected to the HNB-GW 2210 and communicate with the CN 2240 via the HNB-GW 2210. The MGW 2250 is also connected to the CN 2240, downloads announcements and advertisement messages, holds them in the announcement DB 2252 and advertisement message DB 2253, and provides announcements to devices that have started the HNB-GW 2210 by the announcement unit 2251. The MGW 2250 has a function of performing IP⇔ATM (Internet Protocol⇔Asynchronous Transfer Mode) conversion and path control of voice data. Also, the terminal / user server 2260 accumulates mobile terminal and user information in the terminal / user DB 2261 via the CN 2240, analyzes trends and preferences from the history, and provides them to other devices. Various other servers 2270 that store and provide information are connected to the CN 2240 to provide various information.

(Functional configuration of the HNB-GW of the seventh embodiment)
A functional configuration of the HNB-GW 2210 including the MGW function shown in FIG. 22 will be described.

  As shown in FIG. 22, the HNB-GW 2210 is an HNBAP (Home Node B Application Part), a RANAP (Radio Access Network Application Part), or a RUA (RANAP User Adaption) protocol with other devices (UE, HNB, etc.). The communication control unit 211 performs transmission / reception of these signals. Further, when receiving a call from the UE 230, the HNB discriminating unit 212 that discriminates through which HNB 220 the call is received and whether the HNB 220 is an HNB to be announced. In this embodiment, it has UE determination part 2215 which determines whether to announce by the log | history etc. of UE (or user) acquired from the terminal / user server 2260. If the UE is to be announced determined by the UE determining unit 2215, the UE has an announcement specifying unit 2213 that selects the announcement corresponding to the HNB 220 determined by the HNB determining unit 212 and specifies the announcement to the MGW 2250. In addition, an MGW control unit 2214 that controls the MGW 2250 is sent to the UE 230 that has made a call via the HNB 220 so that the announcement designated by the announcement designation unit 2213 corresponding to the arrangement position of the HNB 220 is sent. The MGW control unit 2214 controls the MGW 2250 using a protocol for controlling the MGW represented by Megaco, MGCP, and the like.

A communication system in which the HNB-GW 2210 is replaced with a HeNB-GW is also possible according to the description of the sixth embodiment.

  According to the present embodiment, it is possible to deliver an announcement for alerting “fraud” to outgoing calls from an HNB installed in the vicinity of an automated teller machine (ATM). It is also possible to distribute voice advertisements for outgoing calls from HNBs installed in stores. In this way, a service that takes advantage of the locality of the femtocell becomes possible. In addition, since the small base station is not fixed and can be applied to a mobile base station that can be mounted on a bus, a train, a bullet train, or the like, it can also be used for calling on a deck.

  Furthermore, since position measurement is not performed at the UE by GPS or the like, battery consumption can be suppressed compared to GPS measurement where position measurement is performed at the UE. The UE position can be specified even in underground or buildings where GPS satellites are not visible. Unlike GPS, it is easy to detect a floor in a building or the like. It can also be used for UEs that do not have a GPS function.
