MBMS content is distributed over the channel. The SCC PCH is an example, and may be transmitted on another radio channel, which is not limited to this.

[0020] Next, BM-SC300, which is useful in the present embodiment, will be described with reference to FIG.

[0021] The BM-SC 300 according to the present embodiment includes a radio network controller that distributes user common data, for example, MBMS data, to a plurality of reception sources, for example, mobile stations.

The wireless control device includes a control unit 302, an MBMS data storage unit 304 connected to the control unit 302, an MBMS data transmission unit 306 and a wired transmission unit 312, an MBMS data transmission unit 306 and a wired transmission unit 312, A connected event recognition unit 308 and a transmission path setting unit 310 connected to the event recognition unit 308 and the wired transmission unit 312 are provided. MBMS data storage unit 30 4 is connected to the wired transmission unit 312 and the MBMS data transmission unit 306 is the MBMS data storage unit.

Connected to 304 and the wired transmission unit 312.

[0023] The control unit 302 controls each functional entity included in the wireless control device and controls the operation of the entire device.

[0024] The wired transmission unit 312 transmits the MBMS content distributed from the content provider 400, the MBMS content distribution function after the transmission path setting unit 310 sets the transmission path, and the transmission path setting control signal. Features such as Gmb signaling.

[0025] The MBMS data transmission unit 306 temporarily stores the distributed MBMS content in the MBMS content storage unit 304 (the time for which the transmission path is set).

It has a function to transmit MBMS content.

[0026] The MBMS data storage unit 304 has a function of temporarily storing user common data distributed from the content provider 400, for example, MBMS content.

[0027] The event occurrence recognizing unit 308 has a function of recognizing event occurrence triggered by the delivery of MBMS content from the content provider 400.

[0028] Here, the event will be described.

[0029] The events assumed in this embodiment are classified as follows according to the distribution pattern.

(1) Events that occur at a predetermined timing, that is, events that occur at a limited timing For example, weekly magazines, biweekly magazines, monthly magazines, etc.

(2) Events that occur only once at a sudden timing, that is, events that occur only once, for example, announcement of new products, distribution of new songs, sports broadcasts, live broadcasts, etc.

(3) Events that occur at sudden timings For example, weather information (typhoon information, rain information), disaster information (earthquake information, tsunami information), etc.

(4) Events that occur at random timing For example, sale information, traffic jam information, leisure information (diving information, fishing information, golf information, etc.), investment information, gambling information (in the case of horse racing, odds, horse weight, dividends) , Paddock, etc.)

The distribution pattern described in the present embodiment is an example, and other distribution patterns are not limited to these methods. [0030] Examples of the event shown in (1) include a weekly magazine. In such an event, the release date is specified in advance in the week, and an event occurs at that timing every week. However, if the release date is a holiday (including Obon and New Year holidays), it may be mixed. In such a case, the event occurs randomly.

[0031] Examples of the event shown in (2) include live broadcast distribution. In such an event, the distribution service is performed only once at a predetermined date and time.

[0032] MBMS content corresponding to an event as shown in (1) and (2) is multicast to the user who subscribes to the MBMS service in advance and the event occurs. Therefore, it is the service area in which the user who subscribes to the service is in the area power multicast distribution.

[0033] Examples of content corresponding to the event shown in (3) include weather information and disaster information. It is more effective to broadcast such contents within the service area with a limited distribution area.

[0034] Examples of the content corresponding to the event shown in (4) include sale information. It is more effective to broadcast such content in a limited area. Also, a multicast service that distributes leisure information, investment information, gambling information, etc. only to users who are interested in the MBMS service is effective. That is, M

The area where users who are interested in the BMS service are located is the distribution area. Services with variable factors such as investment information and horse racing information are updated several times a day irregularly. In addition, leisure information is more effective content when the region is limited.

Further, the event occurrence recognition unit 308 recognizes that an event has occurred by the following method.

[0036] (1) Notification of event occurrence from content provider 400

The content provider 400 notifies the occurrence of an event to the BM-SC 300 immediately before delivering the MBMS content.

[0037] (2) BM—Receiving MBMS content with attached information distributed from content provider 400 at SC300 The content provider 400 adds a flag indicating the type of the MBMS content as the attached information to the delivered MBMS content and delivers it. When this MBMS content is received, the event recognition unit 308 recognizes the occurrence of the event by detecting this additional information.

[0038] (3) BM — Analyzing MBMS content delivered from content provider 400 with SC300

The occurrence of an event can be recognized by executing any one of the above forces (1), (2), and (3). You can do everything.

[0039] When the BM-SC 300 receives the MBMS content distributed from the content provider 400, the event recognition unit 308 recognizes the occurrence of the event by analyzing the type of the MBMS content.

[0040] The recognition methods described in the present embodiment are examples, and other recognition methods are not limited to these methods.

[0041] The event recognition unit 308 includes a correspondence table of events and services as shown in FIG. 3, and determines a service type and a service area based on the correspondence table.

[0042] In this event and service correspondence table, event 1 to event 4 are defined as event types, weekly magazine as event 1, new song distribution as event 2, tsunami information as event 3, event 4 Investment information and special sales information

[0043] As a service type and a service area, for weekly magazine, an area where users who are subscribed to multicast and service are present, for new song distribution, subscribe to multicast and service. , Where users are in the area, broadcast and limited areas for tsunami information, areas for investment information where users who are subscribed to multicast and services are located, special sales Broadcast and limited areas are associated with information. The correspondence table shown in FIG. 3 is an example, and is not limited to this configuration.

[0044] For example, when the event recognition unit 308 recognizes the occurrence of an event, the event recognition unit 308 determines a service type and a service area. In accordance with the event recognition method described above, for example, content By adding a flag indicating the event type or content type as additional information to the MBMS content distributed from the provider 400, the event recognition unit 308 recognizes the event type and determines the service type and service area. be able to.

[0045] Transmission path setting section 310 has a function of setting a transmission path for delivering the MBMS content based on the service target area of the event, triggered by the occurrence of an event.

[0046] Next, the operation of the radio network controller according to the present embodiment will be described with reference to FIG.

[0047] User common data, for example, MBMS content is distributed from the content provider 400 to the BM-SC300. The MBMS data transmission unit 306 temporarily stores MBMS content in the distributed MBMS content storage unit 304.

[0048] Next, the event recognition unit 308 confirms whether the event has occurred (step S302). For example, the event recognition unit 308 recognizes the occurrence of an event indicating that MBMS content has been distributed from the content provider 400 by the above-described recognition method. However, the recognition method is not limited to this and may be recognized by other methods.

[0049] When an event occurs (step S302: YES), the event recognition unit 308 detects the service type of the recognized event (step S304). For example, the event recognizing unit 308 determines whether the service type of the recognized event is a multicast service or a broadcast service. On the other hand, if no event has occurred (step S302: NO), the process ends.

[0050] Next, the event recognition unit 308 detects the service target area of the recognized event.

In this case, the event detection unit 308 determines whether or not the service target area is defined in the case of the multicast service, and determines whether or not the service area target area is limited in the case of the broadcast service. To do.

[0051] Next, the transmission path setting unit 310 sets a transmission path according to the service target area in order to distribute MBMS content (step S308). Here, if the mobile stations that have already subscribed to the service are limited according to the event that has occurred, the transmission path setting is the area where the mobile stations that are subscribed to the service are located. This is to secure a transmission path to the radio base station that covers the area. If the service area is limited, the event is specified. Is to secure a transmission path to the radio base station that covers the service area to be performed.

Next, it is confirmed whether or not the transmission path setting is completed (step S310). If the transmission path setting has not been completed (step S310: NO), the process proceeds to step S310. On the other hand, when the transmission path setting is completed (step S310: YES), the MBMS data transmission unit 306 is stored in the MBMS data storage unit 304 by multicast or broadcast, and delivers the MBMS content. (Step S312).

As described above, in the present embodiment, the content pronoider power is also delivered to a plurality of reception sources, triggered by the delivery of user common data, for example, MBMS content. For this reason, it is expected that it will be possible to provide highly immediate content. In addition, it is expected that MBMS content can be provided to the receiving source even for randomly distributed content.
