Next, the CBMAP packet downloaded from the broadcast center (CBC) 20 to the exchange (MSC) 13 and the confirmation package returned from the exchange (MSC) 13 to the broadcast center (CBC) 20 will be described. FIG. 14 is a diagram for explaining the configuration of a CBMAP packet, and FIG. 15 is a diagram for explaining a CBMAP confirmation package.

As described above, the CBMAP packet is a packet organized by the CBMAP conversion unit 28 for each broadcast channel based on the content stored in the content database 25 in the broadcast center (CBC) 20, and as shown in FIG. For example, it is composed of a maximum of 267 octets, and is composed of a CBMAP header, CBMAP BSCCH, and CBMAPBICH, following an IP header and a TCP header compliant with RFC (Request for Comments) describing the specifications of the TCP / IP communication protocol. The CBMAP header is created based on information such as a cell area group name included in the content, and includes a maximum of 67 octets, and includes, for example, a CBMAP header length, an area type, an area identification number, and an emergency identification number. The CBMAPBSCCH is created on the basis of information such as a cell area group name and other download content information included in the content, and includes, for example, a BSCCH length, update information, an on-air information channel number, a cell group number, and the like. The CBMAPBICH is created on the basis of the content body and has a maximum of 131 octets, and is composed of, for example, a BICH length, a message area of the content body, and the like.

The CBMAP confirmation package is a package that is returned from the exchange (MSC) 13 to the broadcast center (CBC) 20 when a CBMAP packet is downloaded, and includes an IP header, a TCP header, a confirmation CBMAPACK, and the like as shown in FIG. Is done.

Next, a transmission / reception sequence between the broadcast center (CBC) 20 and the exchange (MSC) 13 will be described. FIG. 16 shows a normal transmission / reception sequence, and FIG. 17 shows a response timeout sequence.

As shown in FIG. 16, when the first CBMAP packet is downloaded to the exchange (MSC) 13, the broadcast center (CBC) 20 waits for a reply from the exchange (MSC) 13 while monitoring the timer. The exchange (MSC) 13 performs processing for receiving the first CBMAP packet, and returns a CBMAP confirmation package to the broadcast center (CBC) 20 when it is ready to receive the next packet. The broadcast center (CBC) 20 receives this confirmation package and downloads the next second CBMAP packet. Thereafter, the CBMAP packet is transmitted in the same sequence.

Next, as shown in FIG. 17, when the reply of the confirmation package from the exchange (MSC) 13 to the first CBMAP packet downloaded by the broadcasting center (CBC) 20 times out, an alarm is issued. The broadcast center (CBC) 20 retransmits the same first CBMAP packet. When the confirmation package is received within the timeout time, the next second CBMAP packet is downloaded. When the retransmission process is continued, the retransmission process is interrupted by the operator. Since the CBMAP protocol does not have a function of checking an error of a CPMAP packet, the exchange (MSC) 13 transmits a confirmation package to the broadcast center (CBC) 20 and does not return error information. Therefore, if there is a problem with the CPMAP packet downloaded from the broadcasting center (CBC) 20, the CPMAP packet is not unconditionally transmitted to the switching center (MSC) 13 without notifying the broadcasting center (CBC) 20 of an error. Discard it.

Next, the operation of receiving emergency information in the mobile device (MS) 11 will be described. FIG. 22 is a flowchart for explaining the operation of receiving emergency information.

First, in the broadcast center (CBC) 20, highly urgent information is organized as CBMAP packets of the 0th or first broadcast channel and downloaded to the exchange (MSC) 13, and the exchange (MSC) 13 stores this emergency information. The content to be included is arranged in the BPCH as the 0th or 1st emergency broadcast channel, the emergency broadcast channel is configured to be included in the CBC hyperframe multiple times (four times), and the BCCH reception section length of the general call channel (PCH) Is changed so that the mobile station (MS) 11 forcibly receives the BPCH of the emergency broadcast channel. That is, as shown in FIG. 22, when the mobile device (MS) 11 performs intermittent reception of PCH in the standby state (ST11) and there is a change in the BCCH reception section length of the received PCH (ST12), the mobile device ( (MS) 11 receives BCCH (ST13). When there is emergency information on this BCCH, since the P2 bit of the broadcast channel indicating element of the extension information is set to 1, the mobile station (MS) 11 determines that the P2 bit is 1 (ST14). , BPCH is received (ST15). Thereby, when there is emergency information, the mobile station (MS) 11 can immediately enter the BPCH reception, and the 0th or first broadcast channel including the emergency information constitutes all broadcast channels being broadcast. Since it is arranged to be included in the CBC superframe a plurality of times, it can be received in a short time after the emergency information is broadcast.

As described above, according to the above configuration, after the broadcast center (CBC) 20 acquires a plurality of contents from the information service provider arranged outside or inside, and checks the authority of the contents and the consistency of items. Stored in the content database 25, when the on-air period elapses, the CBMAP conversion unit 28 converts it into a cell broadcast map packet defined as a protocol for processing the download together with the area code, and then transmits the packet to a predetermined exchange (MSC) 13. Then, the exchange (MSC) 13 transmits the received cell broadcast map packet through the base station (BS) 12 of the designated broadcast area set for each superframe of the broadcast physical channel provided exclusively, The mobile station (MS) 11 located in this broadcast area receives the broadcast physical channel, and By displaying the contents on the display unit 44, it is possible to selectively provide a large number of different types of information to all the subscribers of the mobile station (MS) 11 at the same time and any one of the large numbers of information. become. Also, since this broadcast information is provided for each broadcast area from the exchange (MSC) 13 via the base station (BS) 12 because the broadcast area is specified in the content acquired by the broadcast center (CBC) 20, It is easy to provide different information. The dedicated broadcast physical channel is set in a time lot adjacent to the conventional common control channel, so that the mobile station (MS) 11 can make frequency switching unnecessary by only increasing the intermittent reception time. Furthermore, the broadcast physical channel has a logical channel including a broadcast information channel including content and a broadcast service control channel including configuration information of the broadcast information channel, and the broadcast service control channel is included in the first frame of one superframe. Since the broadcast information channel is repeatedly set in subsequent frames, the broadcast information for reception can be easily controlled, and the reliability is improved by error correction at the time of reception. All broadcast channels are placed in each superframe of a broadcast hyperframe consisting of multiple superframes, broadcast channels containing emergency information are repeatedly placed in the broadcast hyperframe, and broadcast channel operators By setting information for receiving the broadcast physical channel in the unique definition area and setting information that identifies the presence or absence of emergency information in this information, emergency information such as earthquake information, tsunami information, and typhoon information can be quickly Can be provided.

The mobile station (MS) 11 receives a broadcast information channel corresponding to one broadcast channel repeatedly transmitted in one super frame by the frame assembling unit, discards the frame in which an error has occurred, and receives it normally. By assembling only the frames that have been processed, the reliability of broadcast information can be improved by error correction. Furthermore, the connection processing unit can increase the amount of characters per content by connecting a plurality of broadcast channels based on connection information included in the broadcast service control channel. In addition, the update processing unit can update according to the user's wish by updating the content according to either the set date / time or the update date / time included in the content at the time of receiving operation of the user. Also, by including link information in the content, if this link is selected, Internet browsing becomes possible.

In addition, although the example which comprised the broadcast center (CBC) 20 like embodiment was demonstrated in the said description, when the on-air period comes at least the content acquired from the information service provider, the cell broadcast map containing 1 broadcast channel What is necessary is just to convert to a packet for transmission, and to transmit to the switchboard (MSC) 13, and the check of the content and the conversion to the packet can be arbitrarily performed and are not limited to the embodiment. The broadcast physical channel is a logical channel composed of a broadcast information channel and a broadcast service control channel, one broadcast channel is arranged in one superframe, and all broadcast channels are 64 channels. The form is not limited. Furthermore, the mobile device (MS) 11 can be arbitrarily displayed according to the configuration of the display unit and the like, and, for example, a scroll display can be adopted in addition to the switching display by the screen saver. In other words, it will be readily understood that the invention is not limited to the specific embodiments disclosed, but can be modified within the spirit and scope of the invention as defined in the claims.

As described above, in the present invention, the broadcast center acquires a plurality of contents from the information service provider, converts them into cell broadcast packets including one broadcast channel when the on-air period comes, and the cell broadcast packets To the corresponding exchange, and the exchange sets the packet for each superframe of the dedicated broadcast physical channel and transmits it through the base station in the designated broadcast area. Since the physical channel is received and its contents are displayed on the display unit, information can be set for many different types of broadcast channels and provided to all subscribers in each broadcast area simultaneously, and emergency information is provided. Then we can offer it as soon as possible.
