In the exemplary embodiment, head 310 can have a plurality of ESG fragment descriptor entries 330, described descriptor entry is identified at the ESG fragment 340 in the container payload 320, makes receiver can determine the definite position and/or the length of each ESG fragment 340 of being comprised.For example, in one embodiment, field is stipulated the starting position of specific ESG in container payload 320 by for example deviant 550, beginning and end point or similar are provided.In other embodiments, metadata 350 can be associated with independent ESG fragment 340, near or be positioned among head 310, descriptor entry 330, ESG fragment 340 or its mix.In one exemplary embodiment, the 3GPP metadata envelope can replace or cancel demand relevant specific ESG fragment, that be arranged in the additional metadata of head 310 with the related of ESG fragment 340.
Fig. 4 shows and sends the method that a plurality of single objects transmit, and wherein said transmission is according at least one aspect of the present invention.As shown in Figure 4, transmission object of the present invention (TO) can be carried on, for example, and in (FLUTE) session of the file transfers of one-way transmission or the pure ALC session.In the example of Fig. 4, ESG root channel data, for example IP address, portal number and transmission Session ID (TSI) are announced in IP/MAC notification table 405 (INT table).The FLUTE session of ESG root channel comprises File Delivery Table 410 (FDT) and one or more transmission object (415) of described session.These transmission objects in announcement carousel 430 be included in different ESG part with in order to the mapping between the access parameter of the different ESG methods that send the ESG data.ESG can be different, for example, adopts different language and/or have different coding and style.Described access parameter comprises IP address, portal number, TSI, start and end time, or the like.Described FLUTE session therefore statement how with the ESG data allocations to different sessions.The transmission object 415 of the FLUTE session of carrying mapping (enum) data is described in the FDT of this FLUTE session.The ESG mapping (enum) data can transmit in one or more transmission objects 415.Described mapping can be used XML diagram, simple ASCII text, structuring ASCH text---for example manifold MIME or MIME head, as the binary system of cited type or by other different modes known in the art, realizes.The ESG data transmit with ESG method 440 in one or more transmission objects in this embodiment, and wherein said ESG method can be pure ALC session.Described ESG data can transmit in one or more ESG sessions.In certain embodiments of the invention, ESG data or its part can transmit in one or more FLUTE sessions except the ACL session or alternative ALC session.
Fig. 5 a and 5b show the block diagram along the example frame of the ESG fragment descriptor entries of descriptor entry 500A to 500E of according to the present invention at least one aspect.Frame 500 shows the form of the protocol frame that is used for head 310 (Fig. 3).Frame 502A-D with descriptor entry is an illustrative examples, and it comprises the type of indicating clauses and subclauses 330 and the type field 505 of characteristic.Described type field can be expanded to allow to be used to increase new types of entries.By in field 505, importing entry type, can offer the different information of receiver.We for frame example 502A-D pre-defined the certain metadata that is associated with fragment.For example in 502B, offset field, beginning field, trailer field and basic unified resource identifier (BaseURI) field are the metadata that is used for the respective segments of payload.On the contrary, frame example 502C does not have to be any metadata of fragment association of its expression.
As mentioned above, payload can comprise to be sealed, described sealing is associated self metadata and fragment (both be included in and seal in) or the indication metadata is arranged in head, and perhaps type is the clauses and subclauses of predefine parameter that the ESG fragment that is arranged in described payload is provided.And shown in frame 502C, single descriptor entry can be configured to describe a plurality of ESG fragments by its type, perhaps even the different editions of same ESG fragment.For example, frame 502A is marked as the Class1 clauses and subclauses, and comprises the information about the ESG fragment, for example position, form, version information, unique identifier.For this point is described, frame 502 can provide the extraneous information field about ESG fragment 340 (Fig. 3), for example form 510, version 520, and unique identifier 530.In the exemplary embodiment, whether format field 510 regulation ESG fragments 500 are text, video and/or picture.Yet, those skilled in the art will recognize any information that format fields 510 can stipulate to be included in the medium type in the ESG fragment 340 in fact.
Can comprise version field 520 to allow to upgrade the ESG that had before received.For example, newer ESG version can be detected automatically and be carried out, otherwise the expired ESG fragment of version field 520 defineds can be decided in its sole discretion by the receiver user and is not performed or is performed.But when the local service time spent, this also always of great use.For example, when portable terminal when a geographic area moves to another geographic area, some service may be still available, some may be no longer available, and some may become available.Therefore, some ESG object in new geographic area with the same effective in original geographic area.In an embodiment, terminal can be discerned described ESG object available in new geographic area, and can the no longer valid object of store/buffer.In another embodiment, terminal can receive and the storing ESG object from different frequency, IP platform and Virtual network operator, and afterwards these objects and ESG object from current network is incorporated among the unified ESG.
Alternatively, version field 520 can combine with validity field 570 or be substituted by validity field 570.Whether version field 520 can be indicated the ESG fragment that received is latest edition or is arranged to and determines whether to exist compatibility issue, and validity field 570 can further be distinguished the ESG fragment of useless or lower priority.As shown in Figure 5, one or more validity fields 570 can be indicated the effective time period of associated fragment.Perhaps, validity can be based on the appearance of the hardware of receiver, user-defined setting and/or other ESG.For example, position that node is loaded or the appearance of BaseURI no matter be in validity field 570 or other fields, can allow to verify received ESG fragment.In other embodiments, BaseURI can allow receiver combination or alternative ESG fragment to use the information that is positioned at URI.
The sign that unique identifier field 530 allows the ESG fragment, and no matter the information in the vessel head 310.For example, when a plurality of ESG are received, carry out, perhaps no longer be associated with head, it is overall when discernible perhaps needing, and described information is very useful.Except other employed fields, each in the above-mentioned information field 510,520,530 can comprise alternatively and fill field 540 does not satisfy the byte rule of described clauses and subclauses with compensation part.For example, if the position of ESG fragment comprises the BaseURI that enough bits are not provided for described clauses and subclauses, then can use ascii character (for example 0) to fill requisite space to satisfy the bit requirement.As disclosed, each ESG fragment can be encoded as the bit rate different with other ESG fragments.In another embodiment, different bit rates can be used to the different parameters among the single ESG, for example in different information fields 510,520,530.
The position of ESG fragment can be by utilizing offset field 550 separately or unite and use entry length field 560 obtain, and the skew of wherein said fragment can be from the head, the initial point in the payload, and perhaps any other in the transmission object put and measured.Described field offset and length value can be measured with bit, byte or any similar number system.As previously mentioned, use the field of different system (for example 6 bits, 10 bits, 32 bits) to be coded in the same descriptor entry.Each descriptor entry 500 has the fragment identification field 530 of the described ESG fragment of unique identification.In exemplary descriptor entries 500C, 500D, 500E, BaseURI is appended to sheet segment identification in the payload container to create the unique identifier of the overall situation.
Fig. 6 shows the block diagram of the exemplary containers with a plurality of ESG objects of at least one aspect according to the present invention.Transmission object 600 has the vessel head 610 that is positioned at before the container payload 620, has formed single transmission object together.Head 610 comprises the coded portion about head length 630.Head 610 can comprise the signal transfer mechanism alternatively or transmit encoding mechanism, and it is configured to announce described transmission object or its part with signal and is encoded or compresses.In one embodiment, the LCT code-point that is positioned at the original position of head 610 can comprise that the whole transmission content of head all has been compressed with signal announcement.In other embodiments, reserved field can comprise with the code-point of signal announcement for the coding of transmission object 600.As example, program GZIP can be used to above-mentioned purpose; Yet, those skilled in the art will recognize the purpose that multiple other schemes also can be finished compression in this way.In having the embodiment of reserved field, for example can comprise and ESG, head itself extraneous information that perhaps extra compression or coded message are relevant alternatively.Container payload 620 comprises at least one ESG fragment 640, and the part in the wherein said fragment or all have metadata (as Fig. 3).In some instances, fragment does not have metadata, on the contrary with head 610 that suitable descriptor entry is associated in can find any necessary metadata.Transmission object can be stored in memory, the intermediate transport node of transmitter, and/or in different receivers.
Fig. 7 shows the block diagram of other example frame of the ESG fragment descriptor entries of at least one embodiment according to the present invention.Frame 700,710,720,730 and 740 comprises the type of the frame that type field 750 receives with indication.As mentioned above, type field 750 can be extendible, to allow to increase new types of entries.Frame 700 expressions are used for providing the simple ESG descriptor entry of the position of ESG fragment at payload.In shown embodiment, the deviant of ESG fragment is used to locate described fragment.
Frame 710,720 and 730 shows the dissimilar descriptor entry that is not associated with any container payload.And frame 710,720 and 730 can be used to verify the ESG fragment that has received.In other embodiments, for example shown in the frame 740, descriptor entry can comprise the statement of the BaseURI that is used for entire container.
On the other hand, the present invention comprises a kind of system and method, the container that is used for determining up-to-date transmission whether be before effective renewal of institute's receiving vessel, and need not to decode or the container handling payload in information.In at least one embodiment, transmitter is arranged to a plurality of fragments of renewal as a unit.Aspect another, the present invention comprises a kind of system and method, only needing to be used for the single instance of Container Type to determine the fragment combination at each other possibility example of same type.
Fig. 8 is arranged to the block diagram of simplifying containment system according to an embodiment of the invention that upgrades the previous fragment that receives.Described system is arranged to whether the container of determining up-to-date transmission is effective renewal, and need not to decode or read information in the described container payload.Upgrade container 800 and comprise vessel head 810 and container payload 820 usually.In the exemplary embodiment, head 810 comprises information relevant with number of fragments in the payload 820 and the deviant that is associated; Yet, comprise the information relevant also within the scope of the present invention with head 810 and/or payload 820.Payload 820 comprises the data item 830,840 with fragment update.Although present embodiment has been showed two data item 830,840, payload 820 can comprise additional data items and also can transmit the individual data item.Each data item comprises the indication of its type 850.
Described container can further be indicated the appearance of payload header.For example, the Class1 data item can be the binary envelope that has metadata in head 835 as shown, and head 835 is associated with predetermined fragment.Type 2 can be indicated the 3GPP textual envelope that is associated with different fragments.Therefore described metadata is not fixed on transport layer.Outside above-mentioned example, can define other Container Types.
Described novel update system can be to realize by the configuration of fragment and container instance and management." example of fragment " or " fragment instance " are relevant with the fragment of particular type and version, and wherein " example of container " or " container instance " are relevant with the container that holds specific fragment instance.Fig. 9 shows the container in the update system according to an embodiment of the invention and the block diagram of fragment management.In the exemplary embodiment, FDT 900 and 910 announcement fragments example in groups.When initially receiving first container instance, the clip types in each Container Type is determined by receiver.All different vessels examples of same kind use identical signature---FDT content-position for example, but be to use different transport object identifier (TOI).In the exemplary embodiment, FDT 900 has TOI=5 and FDT 910 has TOI=6, therefore represent different container instances, yet described content type and content-position remains unchanged.Two different vessels examples can use different coding, that is, they have the different content type.For example, hold the Segment A of version A1 and version B1 fragment B container and hold the Segment A of version A2 and the container of the fragment B of version B2 has same Container Type.In addition, the container that holds Segment A (with described version independent) will have distinct Container Type with the container that holds Segment A, B and C (any version).Extra Optional Field, for example content-coding also can remain in according to the preference of transmitter and not change state.For example, if use text meta-data, then entire container can adopt for example GZIP or other technologies known in the art mechanism coding.Perhaps certain part of this container or a plurality of part can be encoded.
Container coding and forward error correction (FEC) can be stated by different mechanisms.For example, the FDT parameter can be stated encoding mechanism.In one embodiment, coding and FEC state by using LCT to expand.Container is encoded as receiver and can determines whether decoding and handle described container and need not visit or read described container.Figure 10 carries out the block diagram that container upgrades according to an embodiment of the invention.In this embodiment, FDT 1010 has TOI=1, and corresponding with the type A container 1020 with example A1, and wherein example A1 can comprise for example fragment 1: example 4 and fragment 2: example 3.FDT 1010 and associated container 1020 are received in terminal, and in end processed or refusal.The renewal that FDT 1030 represents FDT 1010, and after FDT 1010 is received, be received.FDT 1030 is still corresponding with type A container 1040, yet it comprises example A2 rather than example A1, and can comprise variation, and for example fragment 1: but example 4 does not change fragment 2: example 3 is become example 5.In case be received, terminal just determines that example A2 comprises one or more fragment updates of comparing with example A1.Terminal can determine further that A2 comprises the fragment of the same type with A1.In one embodiment, described terminal further determines whether realization A2 according to multiple factor.
Figure 11 to 16 shows the electronic service guidebooks delivery scheme of the various aspects according to the present invention.Figure 16 illustrates exemplary receiver method.At first in step 1610, portable terminal or other receivers obtain required XML pattern (XML Schema) file.This can be by finishing like this: this document is provided in advance, is obtaining this document on the Internet, paying in the session (for example Announcement Carousel or other sessions) reception this document or by being used to receive other modes of data at broadcast files.In step 1620, this receiver also can receive the example that ESG pays descriptor.This can be XML or binary system, and binary instance helps more to compress.(seeing Figure 13 and 14).This descriptor can comprise one or more conversation element.This ESG pays descriptor and can be paid in an ALC transmission object.A plurality of transmission objects can be arranged, and these transmission objects can further comprise the partially or even wholly conversation element of crossover.Like this, do not need FDT.
Next, in step 1630, for each conversation group, receiver can be stored the ESG segment information of being stated that is used for each segmentation of stating.It should be noted that and to use containerID information to point to correct container definitely alternatively.So in step 1640, this receiver can be attached to the ALC/FLUTE session that (be tuned to or add) defines for this conversation element.So in step 1650, this receiver can receive the ALC transmission object.The TOI field can be represented containerID (and version) alternatively.Like this, this transmission object can be container (exemplary syntax of this container shown in Figure 15).
In step 1660, receiver checks that vessel head is right with the segmentation ID/ segmentation version that identification is comprised, and segmentation and the segmentation bookkeeping tabulation that is comprised or stated compared.Be equal to or less than already contained version in this receiver if this receiver runs into the version of segmentation that this receiver known and the segmentation that is run into, then skip over the segmentation that is run into.So, in step 1670, this receiver is compared the tabulation of reception segmentation (in ESG pays descriptor) with the tabulation of statement segmentation, and if stated all be received, then this receiver is determined to have finished and this ESG pays the related payment of descriptor.So this receiver can enter monitoring mode and the monitoring variation that (or in lower floor, for example in PSI/SI Table I NT) triggers on Announcement Carousel.Handle the segmentation that does not skip in step 1680.
Another embodiment of the present invention is below described.A problem of prior art is that the broadcaster may want to state that a plurality of different " view " determine completeness to allow receiver.This difference " view " can comprise the partially or even wholly segmentation of crossover.According to embodiments of the invention, specific ESG segmentation can be mapped to a plurality of sessions.In addition, except conversation group, also have the marshalling of other types, this marshalling is represented " view " but is not comprised any session access information.For example, exist and to present the conversation group that 8 hours program next arranges and to present the conversation group that 8-16 hour program is next arranged.In this conversation group each is stated its oneself ESG segmentation tabulation and is pointed to its oneself carousel (carousel).In addition, have special " physical culture 16h " group, its polymerization jointly present for 16 hours " view " about sports cast next, but do not comprise any conversation description.In this case, expect that this receiver will mainly obtain segmentation by additive method.
Another problem in the prior art with how to provide alternative access relevant to particular group.According to embodiments of the invention, " group " is by vague generalization.ESG pays descriptor can carry the 0...N group.Each group can comprise 0...X switch-in attribute and 0...Y ESG segmentation.In addition, group can comprise and group level (group name for example, validity), insert (for example to the access parameter of FLUTE or ALC session, be used to serve its expansion of access parameter---http://www.exampleserver.com/esg---of the web page server of ESG for group name and/or segmentation ID, or the like) or the ESG segmentation (ID, version, target container, type, or the like) other relevant information.It is as follows that a method of the present invention is handled this problem: broadcaster's definitions section, this group comprise an access (obtaining by interactive channel) that inserts and point to web page server for example pointing to FLUTE/ALC session (broadcast reception).Can exist a plurality of different broadcasting to insert and two-way access simultaneously.This solution can also solve the problem that above-mentioned paragraph is described.
Pointed in the description as top Figure 16, the ESG segmentation that does not skip over can be handled by receiver.In order to handle this segmentation, receiver will typically need correct pattern (schema).Receiver can obtain required schema file with various method, for example to the providing in advance of pattern, receive this document obtaining on the Internet or pay in the session at the broadcast files of for example Announcement carrousel.
Figure 17 illustrates the exemplary process method of the ESG segmentation that is used for not skipping over.It should be noted that if skew and container length are not known, receiver can be determined the position and the length of each ESG segmentation so.Generally speaking---for example GZIP---encodes to each ESG segmentation, can to utilize given segment encoding, the segmentation that like this can following processing be encoded.
At first, in step 1710, the plaintext XML that utilizes the XML syntactic analyser to analyze to carry.This is appreciated that the plaintext that carries does not need additional step analyzed, like this can be analyzed when being paid.In other words, the plaintext that carries can be the document that is independent of operating system, comprises any required context in the document.At this, context refers to pattern or pattern rules, and is sentence structure and the semantic guide that is used to indicate and/or provide the document.
Next, in step 1715, the plaintext that utilizes this XML syntactic analyser analysis to be quoted.It should be noted that and to utilize the pattern of being quoted to come this XML syntactic analyser of initialization, example is provided in Figure 13 and 14, (it can be paid in the descriptor at ESG and provide).Pattern of being quoted or contextual definition the XML structure and provide about which field be that XML document and which field are the information that is used for the grammer of the document.Be appreciated that this pattern can provide with various forms.
In step 1720, the segmentation of GZIP compression separated be pressed into expressly.In step 1725, as discussing in step 1710 and 1715, analyze the segmentation of previous GZIP compression.Next, in step 1730, according to the segmentation of BiM specification handles BiM compression.Certainly, if do not have compressed part charge then can omit step 1720-1730.In addition, if used other compression methods, can suitably handle the part that is compressed of this container so, this part can be an entire container.Like this, in an embodiment, this container needs to decompress before can carrying out any analysis.
It should be noted that and make the ESG segmentation as adopting one or more XML document that carry expressly to be provided and to be well suited for.When there being several such documents in payload, and this container payload is when being compressed (for example payload compression is set to 0x01), and the GZIP algorithm is noted redundancy.
In an embodiment, ESG pays descriptor and can state container by utilizing Container ID to equal TOI.Like this, for example, the container of paying in the session at ESG can be TO1, and it can be the single TO 300 that comprises head 310 and container payload 320 (Fig. 3).This TO can be in Announcement carousel, and this TO can be included in the mapping between the different piece of ESG and can comprise the parameter of visiting by the distinct methods that transmits the ESG data.
In an embodiment, can have a plurality of ESG, and these ESG can be different.For example, different ESG can adopt different language and/or have different codings or different-style.In an embodiment, can come descriptive language by in segmentation, listing field value.
Described an example of Mode A in Figure 13, Mode A is narrated as TOI 7 in Figure 11, and it can be consigned to terminal.In alternative embodiment, terminal can be waited for receiving mode, up to consulted ESG pay the statement in the descriptor or consulted the PSI/SI table identifier with check whether need certain of new ESG or current ESG part after.Only when determining to need pattern, just receive this pattern like this, in an embodiment.
As already pointed out, pattern can provide in advance in an embodiment.In such example, do not use FDT alternatively, but all being ESG, all ALC objects pay descriptor.New ESG pays descriptor can be identified as new TOI appearance.In order to pay the FEC OTI information in the ALC grouping, can use EXT_FTI.
As pointed among Figure 12, when receiving the segmentation 102 that is identified as segmentation id " 102 ", utilize pattern " esgCoreShchema.xsd " to come the corresponding XML-sentence structure of initialization analysis program.As understandable, can use skew to determine the size and the position of segmentation from the following example that provides.
| Id＝82Ver＝2Offset＝0...Id＝102Ver＝3Offset＝259... | Fragm?ent Id＝82 Ver＝2 | Fragm?ent Id＝102 Ver＝3 |
This container can be paid identical with the atom of ALC object or one or more ESG segmentation (XML and/or non-XML).The example of this container sentence structure provides in Figure 15.In an embodiment according to the present invention, respective item is positioned in based on the ESG of segmentation ID 102 and pays in the container of definition among the descriptor X TOI 39.In alternative embodiment, target ESG segmentation can be the XML schema instance that carries, in this case this " type " just statement be used for the Segment type of terminal bookkeeping, thereby and terminal can estimate that the type carries out next step to determine whether condition satisfies.
The tabulation of the one or more segmentations in ESG payment descriptor has defined the notion of integrality.Pay institute in the descriptor when stating segmentation to some extent when having received at ESG, ESG pays session and finishes and can watch this ESG by terminal.
Like this, the sender can tabulate as the segmentation of session by statement and create " view ", and therefore terminal can be watched.An illustrative methods of statement view is to come statement view by time frame as discussed above.Another illustrative methods is to come statement view by broadcasting station/service.
Below be used for ESG pay descriptor the ESG pattern description exemplary embodiment according to aspects of the present invention.Symbol " // " is used for expression to be provided in the preceding paragraph teleological interpretation.Being appreciated that to provide other ESG patterns.

Owing to wish that common mobile device moves and typically have the scope restriction based on the antenna on land, therefore be provided between antenna or the sub-district mobility of great use.Following according to the present invention the example (by Figure 18 and 19 diagrams) of the embodiment of aspect described under the situation that terminal moves among two different ESG zones at platform B (platform_id=0x000011) among the network in two different ESG zones with platform A (platform_id=0x000010) and simultaneously, the use of target_IPv6_esg_root_descriptor.Can the IP data be consigned to all IP decapsulator (IPE) by service system.Each reflector can be presented and meet IPE.As described, flow each platform for all session/IP and have unique destination address, and flow each the ESG zone subclass of platform (give) for all session/IP and have unique source and destination address.
For the ease of understanding, the method for describing among Figure 19 is quoted the pattern of describing among Figure 18.Forward Figure 19 to, in step 1905, terminal is arranged in the sub-district A in zone 1.Terminal needs following information:
Platform?A(platform_id＝0x000010):
Target_IPv6_esg_root_descriptor:
IPv6_source_addr＝ff15::0011
IPv6_destination_addr＝ff15::0111
Platform?B(platform_id＝0x000011):
Target_IPv6_esg_root_descriptor:
IPv6_source_addr＝ff15::0022
IPv6_destination_addr＝ff15::222
Next, in step 1910, terminal moves to sub-district B from sub-district A, and sub-district B also is positioned among the zone 1.During moving, this terminal is carried out the switching from sub-district A to sub-district B.When terminal moved to new sub-district, it received the source and destination address from target_IPv6_esg_root descriptor.If these addresses are identical, when can be like this when sub-district B moves from sub-district A, terminal can infer that it is still in same area (for example zone 1) so.Therefore, terminal does not need to upgrade ESG, unless previous institute obtains to such an extent that ESG is expired.
Next, move to sub-district F from sub-district B, just moving from zone 1 to zone 2 in step 1915 terminal.When terminal moved, this terminal was carried out the switching from sub-district B to sub-district F.This terminal receives the source and destination address from target_IPv6_esg_root descriptor.Because sub-district F is in the zone that is different from sub-district B, therefore the mobile source and destination address of ESG that causes from zone 1 to zone 2 changes as follows:
Platform?A(platform_id＝0x000010):
Target_IPv6_esg_root_descriptor:
IPv6_source_addr＝ff15::0012
IPv6_destination_addr＝ff15::0112
Platform?B(platform_id＝0x000011):
Target_IPv6_esg_root_descriptor:
IPv6_source_addr＝ff15::0023
IPv6_destination_addr＝ff15::0223
Because the source and destination address changes, terminal can infer that the zone changes.Therefore terminal is upgraded ESG, thereby makes ESG corresponding to new region (for example zone 2).Because ESG can provide in segmentation, terminal can have the ability optionally to upgrade different segmentations.In an embodiment, ESG can be identical for zone 1 and zone 2, and terminal can be upgraded ESG in this case.
Next, in step 1920, terminal moves to sub-district G.When terminal moved, this terminal was carried out the switching from sub-district F to sub-district G.Because sub-district F and sub-district G are in same area, the source and destination address of target_IPv6_esg_root descriptor all keeps identical for platform A and platform B.Therefore, terminal can determine that the zone does not change during moving between the sub-district.Like this, if the previous ESG that obtains is expired, terminal can limit the renewal to it.Thus, the mobile any renewal that can not need between sub-district F and G to ESG.
Next, in step 1925, terminal moves to sub-district E from sub-district G.As previously mentioned, this terminal is carried out the switching from sub-district G to sub-district E.Because all in zone 2, it is identical that the source and destination address of target_IPv6_esg_root descriptor keeps for sub-district G and sub-district E.Therefore, terminal can be inferred the zone and do not changed, unless and needn't upgrade ESG it is expired.
Then, in step 1930, terminal moves to sub-district B from sub-district E.As previously mentioned, this terminal is carried out the switching from sub-district E to sub-district B.This terminal is checked the source and destination address of target_IPv6_esg_rootdescriptor, and the source and destination address of definite ESG changes as follows:
Platform?A(platform_id＝0x000010):
Target_IPv6_esg_root_descriptor:
IPv6_source_addr＝ff15::0011
IPv6_destination_addr＝ff15::0111
Platform?B(platform_id＝0x000011):
Target_IPv6_esg_root_descriptor:
IPv6_ource_addr＝ff15::0022
IPv6_destination_addr＝ff15::0222
Because the source and destination address changes, terminal determines that the zone changes.Therefore, terminal is compatibly upgraded ESG.As already pointed out, the renewal of ESG can be restricted to for zone 2 ESG with for the difference between regional 1 the ESG, if any.
Though it is identical with the ESG zone of platform B to it should be noted that the ESG zone of platform A is described to, the zone of A and B can be different in an embodiment.
In a further embodiment according to aspects of the present invention, in ESG payment descriptor, can add additional/optional metadata, for example style, parents' grade (parental rating), title, Service name, record or the like ..., for example can provide by the XML pattern.At this aspect on the other hand, terminal can be configured to based on this is additional/and optionally metadata is selected segmentation in advance, thus decision receives any ESG segmentation.
In one embodiment of the invention, pay ESG by broadcasting one or more ESG payment sessions.In another embodiment, ESG is paid on interactive channel.Perhaps, can use any other transmission, for example the DVB service offering is selected host-host protocol (DVBSTP) or multicast file consignment agreement (MFDP).Even can omit container, in this case, can regard single ESG segmentation as container.
Though invention has been described just to include the specific examples that is used to realize current preference pattern of the present invention, but one skilled in the art should appreciate that, in claims, within the listed the spirit and scope of the present invention, exist multiple variation and displacement about said system and technology.
