Fig. 4 illustrates according to framework first embodiment of the invention, that be used for transmitting at mobile broadcast system notification message.For convenience, only comprise Fig. 1 among Fig. 4 and among the entity described in Fig. 3, be used to transmit the required element of notification message.

With reference to figure 4, SG-G 109 generates the service guide that comprises time, purchase and the access information relevant with service and content in step 401, and sends the request that service guide is transmitted to SG-D 110 then.SG-D 110 sends service guide in step 402 to terminal 119 then.Service guide can transmit via BDS and/or IN respectively by broadcast channel and/or interactive channel.When transmitting service guide by broadcast channel, terminal 119 from transmit service guide via session receive this service guide, and when transmitting service guide by interactive channel, terminal 119 inserts IN and receives service guide then in response to the request of correspondence.

SG-C 120 controls in the terminal 119 receive from the service guide of SG-D 110, and the user service of obtaining and content information from the service guide that receives.Based on this service guide, the user determines reservation and the purchase information at service, scheduling, content etc., uses BSP-C 302 to ask at the service provision such as subscribing and buying then.Receive in order to carry out the related service notification message, BSP-C302 sends to BSP-M 301 in step 403 and subscribes/quit the subscription of request.

In case receive the request at user ID, device ID and service/notice subscription information, BSP-M301 is stored in user information corresponding among the DB 411 among the BSM 113.Be used for providing the entities of various kinds of mobile broadcast service that notification event can take place.In Fig. 4, can in CC 101, BSA104, BSD/A 108 and BSM 113, notification event take place, and in step 404 to 406, CC101, BSA 104 and BSD/A 108 send the request that notification message is generated to NTG 203.

NTG 203 generates notification message at the incident that receives.After generating notification message, NTG203 obtains the destination address TargetAddress that it is sent to notification message from DB 411, and generates the request message that transmits at message then.If exist by interactive channel the Any user that service is subscribed to message sink to be set, then NTG 203 generates and comprises the request message of information that can receive the address of this message about respective user.

In step 407, NTG 203 sends the request that notification message is transmitted to NTDA 202.In step 408, NTDA 202 transmits notification message to NTC 204.In this case, NTDA 202 transmits notification message according to destination address by broadcast channel or interactive channel.

Notification message can roughly be divided into the common notification message that is used for notification service and as the special services notification message of related service supplementary mode.After receiving service guide, terminal or user can discern common notification message and/or special services notification message according to ensuing process.Term " notification service " is meant the service of being made up of notice.For example, notification service is meant on the basis of every day and transmits the service that service (MMS) notification message transmits by Short Message Service (SMS) or Multimedia Message, as " Weather information of today ", " present-day English " etc.Special services notification message as supplementary mode is the example of the assistant service of main program, rather than notification service independently.For example, carrying out ballot that music ranks and the SMS notification message that is used to vote when in the service of broadcasting " preceding 10 ranking lists of music " time is sent to the televiewer when being used to collect vote information, and the notification message that is used to vote is exactly the special services notification message as supplementary mode.This notification service is meant the service of only being made up of notice, and the special services notification message is meant the notification message that can take place in main program.

For notification service, when the COS ServiceType in the service fragment of service guide had the notice value, it was notification service that terminal recognition goes out corresponding service.

For the special services that transmits notification message, terminal can identify it in following situation can receive the notification message relevant with corresponding with service: (i) relevant access fragment comprises element " notice receives " (NotificationReception) 904 o'clock with service, (ii) when with the relevant access fragment of service in element " service class " (ServiceClass) 903 when having the similar notice value of the URI value that indicates " sdo.oma.nt " or its, and (iii) when at service fragment or " bought item " (PurchaseItem) when existence indicates the element of homologous segment of possibility of notification message of reception such as NTviaInteraction or attribute in the fragment.

Fig. 5 A illustrates specific embodiment according to the service guide that comprises notice value first embodiment of the invention, in mobile broadcast system to Fig. 5 D.Because the access fragment among Fig. 5 A and Fig. 5 B is shown specifically, therefore will carry out reference to it in Fig. 9 A and Fig. 9 B.

Fig. 5 A illustrates the example that inserts fragment 901, this access fragment 901 comprises notice reception information, and the notification message relevant with corresponding with service has the access information of the notice that comprises, transmit by broadcast channel in element " notice receive " 904, and comprise with element " access style " 902 in the relevant information of corresponding with service.

Fig. 5 B illustrates the example of the access that comprises service and notification message respectively.Distinguish corresponding access information based on purposes depend on the value of " service class " 903.For example, for file delivery service, " access style " 902 with access of " service class " 903=" sdo.oma.fd " comprises and can be used for the access information that file is downloaded, and " access style " 902 with access of " service class " 903=" sdo.oma.nt " comprises and be used for notification received access information.

Fig. 5 C only illustrates the exemplary configuration of the service of being made up of notification message, and wherein " COS " of service fragment is notification service.A difference between Fig. 5 A and Fig. 5 C is to insert fragment and comprises the address information that is used for the notification message reception, rather than inserts " notice receives " that independently comprises in the fragment.

Reservation/purchase that Fig. 5 D illustrates service has the exemplary configuration of the situation of particular schedule, and corresponding service comprises notice.

As mentioned above, be notification service when " COS ", insert and to comprise " notice receives " 904 or " service class " the 903rd that inserts, during sdo.oma.nt, terminal can identify corresponding service with notify relevant.

Fig. 6 illustrate according to first embodiment of the invention, in mobile broadcast system by the reservation of interactive channel to notification message.

With reference to figure 6, terminal 119 receives service guide in step 601.Afterwards, in step 602, terminal 119 is used the service guide examination notice content of service guide from receiving of describing among Fig. 5, determines whether terminal 119 will pass through the interactive channel reception notification during service subscription/purchase, and determines the reservation to notification message then.

Figure 12 illustrates the framework corresponding with the framework based on OMA of Fig. 2.Show the structure that is used for transmitting the network entity of notification message at CBMS.

With reference to Figure 12, content creating (CC) the 1201st, the supplier of broadcast service, and broadcast service can comprise traditional audio/video broadcast service, music/data file download service or the like.If have any problem or variation when the supply broadcast service, then CC 1201 gives described change notification and serves notification event function (NEF) 1202a that uses among (SA) 1202.NEF 1202a is sent to notice systematic function (NCF) 1203a based on the incident that receives with notification event.

The content-data of the broadcast service that SA 1202 control will provide from CC 1201 be treated to be suitable for radio network form (for example, audio or film are downloaded), so that generation broadcast service data, control generates the essential standardized meta data of service guide, and control generates user's pay imformation.In addition, for the variation of the broadcast service that provides from CC 1201, SA 1202 is sent to NGF 1203a in the Service Management (SM) 1203 with notification event, and the service guide attribute information that will be used to generate notification message offers NGF 1203a.

SM 1203 controls are determined for the transmission scheduling of the broadcast service that provides from SA 1202 and are generated service guide, and SM 1203 is connected to the DVB-H network 1206 of supporting broadcast channel and the Internet 1207 of supporting interactive channel.In addition, the SM 1203 that has notice distribution/reorganization function (NDAF) 1203b therein receives the notification message that transmits from SM 1203, and via the radio network 1206 or the Internet 1207 notification message is sent to a terminal or one group of terminal.SM 1203 has the required session information of NGF1203a, is used to generate the notification message of terminal.This session information is offered NGF 1203a from NDAF1203b.

SM 1203 management is used to receive the subscription information and the service provision information such as indicating the information whether user bought related content of broadcast service, and management is used to receive the device information of the terminal of broadcast service.In addition, SM 1203 is sent to SA 1202 with user's pay imformation, and subscription information, service provision information and device information are offered the radio network 1206 and the Internet 1207.Particularly, when SM 1203 comprises NGF 1203a, the notification message for the notification event of the generation (if any the words that have) of the variation of 1206 that provide from content creating 101, SA 1202, SM 1203 and radio network, as to indicate new function interpolation or existing capability is provided for its, perhaps generates the notification message that indicates the self-incident that broadcast service supplying content (being corresponding broadcast service) will be provided after passing the scheduled time.

Radio network 1026 is the networks that are used to transmit broadcast service.Here, illustrate, the DVB-H network is used as radio network 1206.If there is any variation in the transmission of broadcast service, then radio network 1206 controls are arrived SM 1203 via CBMS-6 interface 1224a or X-3 interface 1224b with described change notification.

The Internet 1207 is based on point-to-point transmission broadcast service, and perhaps the interactively exchange receives relevant control information and additional information with broadcast service.For example, the Internet 1207 can be existing cellular network, for example 3GPP Wideband Code Division Multiple Access (WCDMA) (WCDMA) network.

Terminal 1208 is the terminals that can receive broadcast service, and has the function that can be connected with cellular network according to terminal capabilities.Terminal 1208 is assumed to be the terminal that can be connected to cellular network.Client's function (NCF) 1208a is notified in use, terminal 1208 receives the notification message that transmits via CBMS-5 1225 interfaces, and carry out the operation that is suitable for it, perhaps receive the notification message that transmits via CBMS-4 interface 1226, and carry out the operation that is suitable for it.

CBMS-7 interface 1222 is the interfaces of the NGF1203a of NEF 1202a in the SM 1203 from SA 1202, and (for example transport the required information of generation event notice or notification message, the attribute information of service guide), thus NGF 1203a can generate notification message.

CBMS-3 interface 1225 is employed interfaces when the notification message of the transmission of the NDAF 1203b from SM 1203 directly is sent to terminal 1208 by broadcast channel via radio network 1206.This interface is used to notification message is sent to one or more terminals.

CBMS-4 interface 1226 is that the notification message that transmits as the NDAF 1203b from SM 1203 is by dedicated channel or the broadcast channel that provides in by the Internet 1207, employed interface when directly being sent to terminal 1208 via the Internet 1207.This interface is used to notification message is sent to one or more terminals.

CBMS-6 interface 1224a is the interface between SM 1203 and the radio network 1206, is used for the transfer path that uses or is used for setting up the RX path of the event information that radio network 1206 generates in radio network 1206 is set up by SM 1203.

X-3 interface 1224b is the interface that is used to set up the transfer path that will use between the SM 1203 and the Internet 1207.

CBMS-1 interface 1233 is the interfaces that are transported to terminal 1208 by its control information with radio network 1206.In DVB-H, the control signal channel that is called PSI/SI (PSI/SI) is corresponding to this interface.

NEF 1202a control will generate the required information of notification message and be sent to NGF 1203a, and the information of controlling the generation (if any) that will indicate notification event is sent to NGF 1203a.NGF 1203a control is used from NEF 1202a being used to of receiving and is generated the required information of notification message and incident generates notification message, perhaps be controlled at when receiving notification event from radio network 1206 and generate notification message, and control is sent to NDAF 1203b with notification message via NDAF 1203b.(i) when the beginning of needs notification service again, (ii) when it when CC 1201 receives the notice of the variation that indicates information on services and when needing to transmit new service guide, (iii) when particular event having taken place in radio network 1206, NGF 1203a can generate notification message.

NDAF 1203b control transmits notification message via CBMS-3 interface 1225 or CBMS-4 interface 1226.In addition, in case receive from radio network 1206 and to indicate because during the information of the variation the specific mobile broadcast service that wireless network environment causes (for example indicating the information of rate controlled or service impossibility), NDAF 1203b is sent to NGF 1203a with the notification event of correspondence.

Compare with the entity of Fig. 2, in definition and nominally, be equivalent to those entities among OMA and the CBMS, therefore the description to it is not provided here corresponding to the network entity of notification message.For interface, NT-6 is corresponding to CBMS-4, and NT-5 is corresponding to CBMS-3.
