Now will be in conjunction with the broadcast/group broadcast that the networking internetwork roaming is provided (BCAST) operation system and the method that are described with reference to the drawings according to a preferred embodiment of the invention.

In the present invention, user's (having portable terminal) of the BCAST business that provides when the local network of having subscribed by terminal is when local network roams into accesses network, and the identical BCAST business that provides in the local network can be provided in accesses network the user.In the case, the user of the business guide that this accesses network can send local network in the visit network, or combine the business guide of local network with the business guide of accesses network and it is sent to user in the accesses network.

In the present invention, when the user who has subscribed specific BCAST business when user's local network roams into accesses network, this accesses network is checked user's business authentication and is provided for browsing the terminal that the public keys (right object) of the content of the BCAST business in the accesses network is given the user from local network.

In the present invention, when the user who has subscribed particular B CAST business when broadcast type network roams into another identical broadcast type network, or to different broadcast type network, or to non-broadcast type network, this user can receive the BCAST business all the time by the network of roaming.

Fig. 1 is the block diagram that has shown according to the structure of the BCAST operation system of the embodiment of the invention.The all component of this BCAST operation system is by exercisable coupling.

As shown in Figure 1; this BCAST operation system comprises that content provides device (content generation) 10; be used for providing content to distribute in the BCAST business; broadcast/group broadcast (BCAST) server 17; be used to provide BCAST business protection or this BCAST business of maintenance/management to user or execution content; and terminal 30, be used for receiving the BCAST business of selecting by the user from BCAST server 17.This terminal 30 is portable terminals, such as mobile phone, and PDA or the like.With include input unit (for example keyboard, button or the like), controller, memory or the like known elements.

This BCAST operation system is additional comprises broadcast distribution system (BDS) 20 or the Internet (IN) 22, BCAST business and the interactive function of carrying out two-way communication are used to distribute, and/or BDS service distribution (BDS-SD) unit 18, be used for providing the application Internet according to carrying.This unit 18,20 and 22 relates to the BCAST business tine that server 17 is provided and is distributed to suitable equipment, such as terminal 30 or this locality or accesses network.

This BDS20 or the Internet 22 provide the carrying of BCAST business, such as DVB-H (digital video broadcasting processing), MBMS (multimedia broadcast-multicast service), BCMCS (broadcasting multicast service), ISDB-T (integrated service digital broadcasting-land), or T/S DMB (land/satellite-DMB).Therefore, this BDS20 and the Internet 22 are supported broadcast mechanism.

This BCAST server 17 comprises BCAST service application (BSA) unit 12; be used to carry out function such as protection BCAST business tine and/or maintenance/management BCAST business; BCAST service distribution/adaptive (BSDA) unit 14; be used for carrying out and control broadcasting, interface and content arrangement of time function; by using specific carrying (DVB-H; MBMS; BCMCS; or the like); with BCAST reservation management (BSM) unit 16, the function that is used for execute protection/management service/content and maintenance/leading subscriber reservation is so that the user of BCAST business has been subscribed in management.In the case, the BSA unit 12 of BCAST server 17, BCAST service distribution/adaptation unit 14 and BCAST reservation/administrative unit 16 transmission or exchange message and signal or each other by intercommunication each other.Can directly or by one or more BDS-SD unit 18, BDS20 and the Internet 22 be communicated to last destination equipment (for example terminal 30) from communicating by letter of BSDA unit 14 and BSM unit 16.

This terminal 30 comprises application/software and the application program that is used to receive the BCAST business, is used to store and a part of editing the BCAST service lists that BCAST service provider provides and the information of the preferred channel of the relevant user of storage.Based on the BCAST service lists that the service provider provides, the professional preference of BCAST of being edited and being produced by the user by reflection user's preference is known as expectation tabulation (wish list).Terminal 30 and its network of relation (for example local network) can comprise the application program that is used to manage the expectation tabulation, and it is known as the expectation list management and uses.This terminal 30 can be mobile phone, PDA or the like, but is not limited thereto, and can be any equipment that is configured to receive the BCAST business.

This independently management expectation tabulation of expectation list management application management, and when different BCAST service lists that the user of the terminal of the business of having subscribed specific provider roams into the service area of different providers and receives that corresponding provider provides, expectation tabulation of this expectation list management application stores and editor's part.When the service lists of the BCAST that provides in the local network of relevant terminal is not provided the service provider of the accesses network that the user has roamed into, this expectation list management application receives service lists and stores it from local network in advance, or a business of being selected by the user in the service lists that storage is provided in the expectation tabulation in advance.

The service lists that provides in the service lists that provides in different service providers' the network and its network can be provided the roaming contract that provides the service provider of specific transactions to utilize the service provider to make.In the case, the service provider will show that this business is the business that the business that provides of different providers and service provider itself do not provide.In other words, this BCAST business comprises an expectation tabulation inspection application program, it takes out expectation tabulation of user terminal and whether the current any business that can provide in the expectation tabulation of BCAST server is provided, if the BCAST business can not provide the business in the expectation tabulation, its checks that whether different provider or different servers can provide it.

The expectation tabulation checks that application program may reside in each BCAST server, and when contact was roamed in existence between the service provider, the expectation tabulation in the BCAST server of different providers checked that application program energy interworking is so that can provide the business of being asked by the user in the business that each BCAST server provides.It should be noted that ' the expectation tabulation of terminal ' is meant identical also can being used by exchange below with ' user's expectation tabulation '.

This BCAST server 17 can periodically be checked the expectation tabulation of terminal 30 and store in its memory cell as the part in the service broadcast tabulation (server B CAST tabulation) of server 17 storages or the separation outside the BCAST server.This BCAST server 17 can be stored (or in the memory cell of separating) relevant information that has been offered the business of each requesting users by different service providers therein.Therefore, when after this user who determines asks BCAST professional, current user's history that this BCAST server 17 is searched for its memory cell and obtained the BCAST business.And this information can be used by BCAST server or other server in case the BCAST business that request is provided more easily and faster to current user.In addition, even the user does not provide user's expectation to tabulate to the BCAST server, because the corresponding information of this BCAST server stores, this BCAST service can be provided for the user.

Fig. 2 example according to three of the embodiment of the invention different examples, wherein the BCAST business can be roamed and be received all the time to terminal.

As shown in Figure 2, the user of terminal can roam in (for example between the MBMS) between the identical broadcast type network, can roam in (for example between MBMS and the DVB-H) between the different broadcast type network, maybe can roam between broadcast type network and the non-broadcast type network.In the 3rd example, broadcast type network is not limited to MBMS or DVB-H, and can be BCMCS, ISDB-T, and T/S-DMB, or other, but not broadcast type network can be GSM or CDMA, its roundabout BCAST of providing is professional or do not support broadcast mechanism.

In some embodiments of the invention, to have subscribed the BCAST of one or more local networks professional and roam into may be another network (accesses network) of the radio network of same type or dissimilar radio network the time when terminal (user), by obtaining the BCAST business of local network, this accesses network is configured to provides the BCAST of local network business to give terminal in the accesses network to terminal and broadcast BC AST business (content).In another embodiment, the BCAST business of this accesses network can offer the terminal of roaming in the accesses network, as long as accesses network is carried out the business authentication inspection of terminal by the local network of terminal.In addition, even accesses network is not support the non-broadcast type network of broadcast mechanism, this accesses network utilizes mode of unicast to offer the terminal of roaming in the accesses network to the BCAST business of local network all the time.For example, even being non-broadcast type network, accesses network also only provide general mobile communication business, this accesses network can provide MBMS business or DVB-H business all the time to terminal.

Fig. 3 is the signal flow graph of BCAST operational approach according to an embodiment of the invention.Supposed that before the user roams into accesses network 200 user of terminal 300 has subscribed one or more BCAST business that the local network 100 of terminal 300 provides.Local network 100 can comprise BSA unit 110, BSM unit 120, BSDA unit 130 and BDS-SD unit or BDS or IN140.This accesses network 200 can comprise BSA unit 210, BSM unit 220, BSDA unit 230 and BDS-SD unit or BDS or IN240.Terminal 300 has the structure identical with the terminal 30 of Fig. 1.These assemblies of this system came into question in the connection of Fig. 1.Local network 100 can be identical broadcast type network or different broadcast type network with accesses network 200.All parts of Fig. 3 operationally are coupled.

Now, with reference to figure 3, when wanting on current location (the accesses network), the user who roams into the terminal 300 of accesses network 200 from local network 100 receives BCAST when professional, the BCAST application program of this user's operating terminal 300, and then, terminal 300 sends the BCAST service guide request message or the BCAST business request information arrives the BSM unit 220 (step S11) of visiting network 200.This request message can comprise identification information of user/terminal or the like.

This BSM unit 220 is by the BSDA unit 230 relevant BCAST service guide request message of intercommunication notice accesses network or the reception (step S13) of BCAST business request information, and the business authentication (step S15) of inspection user terminal.For example, 220 send the BSM120 of service authentication request message from the BSM unit to local network.In the case, because terminal use's BCAST service subscription information (for example, business that relevant user has subscribed or bundling information) be present in the local network 100, the BSM unit 220 of accesses network is asked users' subscription information (for example, by sending user/Termination ID or the like) and is carried out business authentication from the BSM unit 120 of local network.The subscriber that the current user/terminal of checking is the BCAST business that provided by local network 100 can be provided this business authentication.In replaceable mode, this local network 100 can be carried out actual business authentication and accesses network 200 just in time receives the result of business authentications from local network 100.For this point, can comprise the result of business authentication inspection and/or be used for the information of required other of the subsequent process of accesses network 200 from the service authentication response message of 120 to BSM unit 220, BSM unit.

Based on the business authentication of checking terminal 300, the BSM unit 220 of accesses network has been finished and current user/terminal certified (step S17) by intercommunication notice BSDA unit 230 these business authentications.At this moment, this BSDA unit 230 checks whether the server B CAST of storage in accesses network 200 has the expectation tabulation that is used for the active user in tabulating.This server B CAST tabulation is stored in the BCAST server of accesses network 200, and can be present in BSA unit 210, in BSM unit 220 or in BSDA unit 230, maybe can be stored in the independent memory cell.Check that by the expectation tabulation application program can management server BCAST tabulation.This server B CAST tabulation comprises the expectation tabulation of a plurality of different users.An expectation tabulation of user/terminal is user's a preferred BCAST business, select the tabulation of all BCAST business that it can be provided from user's local network by the user, or select the tabulation of all BCAST business of having subscribed from user's local network from the user.The expectation of this terminal tabulation can also comprise other the information such as user profile, and this user profile can be used to produce business guide.

Active user's expectation tabulation can be stored the part as the server B CAST tabulation of storage in the accesses network 200.For example, before the user roamed into accesses network, this accesses network can be by tabulating with the expectation that communicating by letter of local network obtains the user in advance.This can realize in many different modes.For example, in case the user has subscribed the BCAST business of local network 100 and tabulated based on the expectation of the BCAST service lists compiling user that is provided by local network 100, this local network 100 can be configured to send expectation and tabulate visit network 200 so that it can be pre-stored in the accesses network 200.In addition, this system can also be configured to be communicated to accesses network 200 so that be stored in the user's of any renewal in local network 100 and/or the terminal 300 expectation tabulation from local network 100 or terminal 300.

In the example of Fig. 3, suppose on the server of accesses network, not exist the expectation tabulation of current terminal 300.Yet, do not exist the situation of the expectation tabulation of current terminal 300 after this to come into question on the access web server in conjunction with Fig. 4.

If at step S17, the expectation of terminal 300 tabulation is not present in the server B CAST tabulation, and then the BSDA unit 230 of accesses network sends the BSDA unit 130 (step S19) of service guide request message to local network 100.Various information (are for example collected through intercommunication from the BSM unit 120 and the BSA unit 110 of local network 100 in the BSDA unit 130 of local network then, subscription information, expectation tabulation of user or the like), be used for current terminal 300 is produced business guide (step S21).After this, this BSDA unit 130 is based on the expectation list producing business guide (BCAST business guide) of current terminal.

The BSDA unit 130 of local network sends the BSDA unit 230 (step S23) that the business guide that produces arrives the visit network, and the BSDA unit 230 of accesses network sends business guides to terminal 300 (step S25).In the case, the BSDA unit 230 of accesses network can send the business guide that receives from the BSDA unit 130 of local network to terminal 300, the new business guide that business guide obtained that maybe can send the business guide by merging accesses network 200 and receive from the BSDA unit 130 of local network.In other words, the business guide that sends to the BSDA unit 230 of accesses network from the BSDA unit 130 of local network can be identical business guide or different business guides with BSDA unit 230 from accesses network to the business guide that terminal 300 sends.In step S31, accesses network 200 is broadcast to terminal 300 to business guide by the broadcast mechanism that uses it, for example by the broadcast distribution system (for example BDS20 among Fig. 1) or the Internet (for example IT22 among Fig. 1).

When BCAST business guide that customer inspection terminal 300 receives and when selecting in the program discerned in the BCAST business guide or the content the received content of expectation (BCAST business), terminal 300 sends the BSDA unit 230 (step S27) of BCAST content request message to the visit network.In the case, the content of expectation is the BCAST business that provides in the local network.Therefore the BSDA unit 230 of accesses network sends the BSDA unit 130 (step S27) of BCAST content request message to local network.

Based on having received the BCAST content request message, this BSDA unit 130 provides device 50 to receive the content (step S29) that the user asks by the intercommunication with BSA unit 110 from content, and sends the content (BCAST business) of reception to terminal 300 (step S31) by the BSDA unit 230 of accesses network.Accesses network 200 sends content to terminal 300 by the broadcast mechanism that utilizes it.Thereby the user who roams in the accesses network receives the BCAST business of user's local network.

Fig. 4 is the signal flow graph of BCAST operational approach in accordance with another embodiment of the present invention, and wherein current terminal 300 roams into accesses network 200.The system unit of discussing among the embodiment of Fig. 3 also is provided among the embodiment of Fig. 4.In Fig. 4, in the server B CAST of the BCAST of accesses network 200 server tabulation, have the expectation tabulation of current terminal 300, this is different from the embodiment of Fig. 3.Local network 100 can be identical broadcast type network or different broadcast type network with accesses network 200.Supposed that before the user roams into accesses network 200 user of terminal 300 has subscribed one or more BCAST business that the local network 100 by terminal 300 provides.All parts of Fig. 4 operationally are coupled.

With reference to figure 4, receive BCAST when professional when the user who roams into the terminal 300 of accesses network 200 from local network 100 wants current location accesses network 200, the BCAST application program of this user's operating terminal 300 and send the BCAST service guide request message or the BCAST business request information to the BSM unit 220 (step S41) of visit network.

The BSDA unit 230 relevant BCAST service guide request message of accesses network or the reception (step S43) of BCAST business request information are notified by intercommunication in this BSM unit 220, and check the business authentication (step S45) of terminal/subscriber by the BSM unit 120 of local network.Step S41, S43 and S45 correspond respectively to the step S11 of Fig. 3, S13 and S15.

Based on the business authentication of checking terminal/subscriber, the BSM unit 220 of this accesses network has been done and the current certified reception of user BCAST business (step S47) by the business authentication of intercommunication notice BSDA unit 230 current terminals 300.At step S47, the expectation tabulation that whether has terminal 300 in server B CAST tabulation is checked in the BSDA unit 220 of accesses network then.This server B CAST tabulation is present in the BCAST server of accesses network, and it may reside in the BSA unit 210, is present in BSM unit 220 or the BSDA unit 230, and can check that application program manage by the expectation tabulation.

If have the expectation tabulation of terminal 300 in the server B CAST of accesses network tabulation, this BSDA unit 230 sends the BCAST business guide to terminal 300 (step 49).In the case, the BCAST business guide that the BSDA unit 230 of accesses network can send local network 100 based on the expectation of terminal 300 tabulation is to terminal 300, maybe can send new business guide that the BCAST business guide by merging accesses network 200 obtained to the BCAST business guide of local network 100 to terminal 300.In addition, various information (for example BCAST service attribute or the like) can be collected from the BSM unit 220 of accesses network and BSA unit 210 in the BSDA unit 230 of accesses network, are used for based on the business guide of the expectation list producing terminal 300 of terminal 300 and produce the BCAST business guide that is used for terminal 300.This accesses network 200 can send business guide to terminal 300 by the broadcast mechanism that uses it, for example, and by the broadcast distribution system (for example BDS of Fig. 1) or the Internet (for example IT22 of Fig. 1).

When BCAST business guide that is received by terminal 300 when customer inspection and interior perhaps professional described in the business guide of selecting in program that expectation receives, this terminal 300 sends the BSDA unit 130 (step S51) of BCAST content request message to local network by the BSDA unit 230 of accesses network.

Based on having received the BCAST content request message, the BSDA unit 130 of local network provides device 50 to receive the content (step S53) that the user asks by the intercommunication with BSA unit 110 from content, and sends the content (BCAST business) of reception to terminal 300 (step S55) by the BSDA unit 230 of accesses network.Accesses network 200 sends the BCAST business tine to terminal 300 by the broadcast mechanism that uses it.Thereby, roam in the BCAST business that user in the accesses network receives user's local network.

Fig. 5 is the signal flow graph of BCAST operational approach in accordance with another embodiment of the present invention.The embodiment that this embodiment is different from Fig. 3 and 4 is that accesses network 400 is non-broadcast type network.Although accesses network 400 does not directly provide the BCAST business, the terminal use is according to the unicast method reception BCAST business of this embodiment by accesses network.Before the user roamed into accesses network 400, the user of terminal 300 had subscribed the BCAST business of local network.All parts of Fig. 5 operationally are coupled.

As shown in Figure 5, because the non-broadcast type network (accesses network 400) represented by wireless network or mobile communications network does not have the entity that the BCAST business is provided, it sends the business guide that sends from local network 100 and/or content to current terminal 300 by its packet switching network.In other words, utilize existing communication protocol generation accesses network 400 between accesses network 400 and the terminal 300 and the communication between the terminal 300.

With reference to figure 5, when the user of terminal 300 roaming or (in other words from user's local network 100, (accesses network 400 when broadcast type network) moving to another network, be non-broadcast type network), the user operates the BCAST application program of user terminal 300 and terminal 300 sends the BCAST service guide request message or the BCAST business request information arrives non-broadcast-type accesses network 400 (step S61).

Based on having received request message, non-broadcast-type accesses network (for example one of them server) 400 is asked the business authentication (step S63) of the BSM unit 120 of local networks 100 with the inspection terminal use, and the BSM unit 120 of local network checks that terminal uses' business authentication and the response message that transmission comprises service authentication result arrive non-broadcast-type accesses network 400 (step S65).In the case, because terminal use's BCAST service subscription information (for example, the business that relevant user has subscribed or the information of bundling) be present in the local network 100, accesses network 400 is asked users' subscription information (for example, by sending user/Termination ID or the like) and is carried out business authentication from the BSM unit 120 of local network.The subscriber that the current user/terminal of checking is the BCAST business that provided by local network 100 can be provided this business authentication.In replaceable mode, local network 100 can be carried out actual business authentication, and accesses network 400 just in time receives the result of business authentication from local network 100.

Based on the business authentication of checking terminal 300, non-broadcast-type accesses network 400 sends the BSDA unit 130 (step S67) of service guide request message to local network.Based on having received service guide request message, the BSDA unit 130 of local network by intercommunication from the BSM unit 120 of local network and the business guide information (step S69) of BSA unit 110 collection terminals 300.In the case, since accesses network 400 be non-broadcast-type and therefore do not have an entity (through broadcast mechanism) that the BCAST business is provided, expectation tabulation or the business guide for the terminal 300 of the BCAST business that provides from local network or any other network itself is not provided this accesses network 400.Thereby, accesses network 400 must obtain the business guide of terminal 300 from the BSDA unit 130 of local network, and based on expectation tabulation that prestored by local network or the terminal 300 that terminal 300 provides, the business guide information that is used for current terminal 300 is collected in the BSDA unit 130 of local network.

Then, the BSDA unit 130 of local network utilizes the business guide information of collecting to produce the BCAST business guide that is used for current terminal 300.This BSDA unit 130 then sends the business guide that produces and arrives visit network 400 (step S71), and this accesses network 400 sends business guide to terminal 300 (step S71).In the case, accesses network 400 business guide that sends to terminal 300 is identical with the business guide that receives from local network 100.

BCAST business guide when 300 receptions of customer inspection terminal, and when selecting content that expectation receives in program of listing and the business in business guide, this terminal 300 sends the BSDA unit 130 (step S73) of BCAST content request message to local network by accesses network 400.

Based on having received the BCAST content request message, the BSDA unit 130 of local network provides device 50 to receive the content (step S75) that the user asks by the intercommunication with BSA unit 110 from content, and sends content corresponding to terminal 300 (step S77) by non-broadcast-type accesses network 400.In the case, received the accesses network 400 of content (BCAST business) from the BSDA unit 130 of local network and sent content to terminal 300 by its packet switching network/method, this is owing to accesses network 400 is non-broadcast type network.In other words, only between non-broadcast-type accesses network 400 and terminal 300, transmitted content (BCAST business) with 1: 1, the broadcast distribution system (BDS) or the Internet for example are not provided by the data traffic channels that provides in the mobile communications network by mode of unicast.

In the embodiment of Fig. 5, if audio/video codec of supporting in the network that BCAST business (broadcast type network) is provided and the audio/video codec of supporting in visit mobile communications network (non-broadcast type network) are not corresponding, the conversion process of determining that can use codec to correspond to each other.For example, provide the broadcast type network of BCAST business tine to support MPEG4, and the mobile communications network (non-broadcast-type accesses network) that is used to receive the BCAST business tine is supported MPEG2, do not support MPEG4, then the mobile communications network MPEG-4 content that is configured to decode and receives from broadcast type network is encoded to MPEG2 to them and then sends the MPEG-2 content to user terminal.In the case, before content is provided, can add the process that is used for exchanging the content encoding mode of supporting in content encoding mode that broadcast type network supports and the mobile communications network (non-broadcast type network), and this process is known.In addition, if the ability that local network is known user terminal (for example, the codec of supporting, data transfer rate, the screen resolution of terminal), then corresponding information (for example ability information of terminal) can be sent to accesses network so that accesses network can be used this information, with before content is sent to user terminal, and the content that suitable conversion receives from local network.

In the embodiment of Fig. 3-5, the expectation tabulation of having described the active user is used to produce the business guide that offers the terminal of roaming in the accesses network.Yet, the invention is not restricted to this, and surround such a case, wherein active user's expectation tabulation is not used to the active user on the terminal is produced business guide.For example, do not consider user's expectation tabulation, the business guide that is provided to the terminal temperature difference on the terminal 300 can be based on the business guide that user's reservation policy produces, and maybe can be the business guide of all BCAST business of comprising that this locality or accesses network provide.

Fig. 6 is the signal flow graph of BCAST operational approach in accordance with another embodiment of the present invention.In this embodiment, before terminal request BCAST business guide, send the BCAST business guide to terminal 300 from accesses network 200.In other words, the accesses network of broadcast type network utilizes its business guide of broadcasting of its broadcast mechanism (for example BDS or the Internet) repetition to enter all terminals of accesses network to roaming.Each terminal then can be asked the one or more BCAST business on visit (request right object) business guide, and therefore visits this BCAST business.

In Fig. 6, supposed that before the user roams into accesses network 200 user of current terminal 300 has subscribed one or more (BCAST) business that the local network 100 of terminal 300 provides.Local network 100 can comprise BSA unit 110, BSM unit 120, BSDA unit 130 and BDS-SD unit or BDS or IN140.This accesses network 200 can comprise BSA unit 210, BSM unit 220, BSDA unit 230 and BDS-SD unit or BDS or IN240.These parts have been described in conjunction with Fig. 1.Local network 100 can be identical broadcast type network or different broadcast type network with accesses network 200.All parts of Fig. 6 operationally are coupled.

Now, with reference to figure 6, roamed into the BCAST business guide of the terminal 300 of accesses network 200, and need not be connected (step S81) with local network 100 from the BSDA unit 230 reception accesses network 200 of accesses network.In other words, accesses network 200 provides its business guide to the terminal 300 that roams into accesses network 200, and without user's request with need not get in touch with any of local network 100.This can finish by accesses network 200, enters all terminals of accesses network 200 by its business of broadcasting that repeats to roaming, for example, uses its broadcast mechanism.

Based on checking business guide, the user asks to use special permission (visit information, for example right object RO) so that the specific BCAST business (step S83) that visit is discerned from the business guide of the BSM unit 220 of accesses network.This use special permission is the right at a kind of right of the content of user's request or visit or use BCAST business.The BSM unit 220 of accesses network receives the business authentication of this request and inspection relevant terminal 300 from the BSM unit 120 of local network.In other words, the BSM unit 220 of accesses network sends the BSM unit 120 (step S85) of service authentication request message to local network, and the BSM unit 120 of local network is checked the business authentication of terminal and sent the BSM unit 220 (step S87) of service authentication response message to the visit network.This service authentication response message comprises the result of business authentication.This business authentication can comprise and determines whether that current terminal 300 is subscribers of local network 100, and the details of the user's of examination terminal 300 reservation is so that determine whether that the user is with the specific BCAST business of receiving step S81 by user's request.Can carry out actual business authentication by local network 100, or by accesses network, or partly by local network with partly pass through accesses network.

If service authentication result shows terminal 300 certified reception BCAST business, the BSM unit 220 of this accesses network send be used to allow to visit and/or use the specific BCAST business that the user asks use special permission (visit information is such as RO) to user (step S89).RO can be that key or code are to open or to decipher BCAST business (content).The BSDA unit 230 of accesses network sends the content (BCAST business) of user's request to terminal 300 by its broadcast mechanism.In the case, this BSDA unit 230 and BSM unit 220 can transmission or exchange message and signals by intercommunication.

Based on this content that receives, terminal 300 visits or explains the content of reception by using RO.Use according to corresponding contents, the BSM unit 220 of accesses network (for example produces (charging) information of record keeping, relevant user uses charging of content or the like) (step S93), and accesses network 200 can send the charge information that produces to local network 100 in case can by local network can be correct the user is chargeed.Because the user has the subscription contract with local network 100, the business that this accesses network 200 provides at accesses network sends charge information to local network 100.This charge information can comprise any other service charge of the accesses network 200 that is used to allow the roamer to receive the BCAST business.

According to the present invention, the step of the generation charge information among the step S93 can also be performed in other embodiments, for example, and in the embodiment of Fig. 3-5.For example, if accesses network only is provided by the BCAST business tine that is provided by local network, this charge information can comprise any service charge of the accesses network 200 that is used for only transmitting the BCAST business tine.

As mentioned above, broadcast/multicast service system and the method according to the network enabled internetwork roaming of the embodiment of the invention has many advantages.

For example, after terminal roaming entered accesses network, on the current location in accesses network, it can receive the professional identical BCAST business of the BCAST that has received with this terminal immediately in local network.

In addition, because the user can have successional setting and (for example receive professional and let it be the position of his/her preferred BCAST, whether the user is currently located at local network or accesses network), the convenience and the satisfaction that are used to receive the user of BCAST business can be strengthened greatly.

Aforesaid embodiment and advantage are exemplary and can not be construed as limiting the present invention.Instruction of the present invention is easy to be applied to the device of other type.Description of the invention is intended to example, and does not limit the scope of claim.To those skilled in the art, many replacements, modifications and variations are conspicuous.In claims, the statement of device-Jia-function is intended to cover the structure of performed described function described herein, is not only structural equivalents and is the structure of equivalence.
