Description
Technical field
The present invention relates to the application layer technology of mobile communication, particularly a kind of method, server end and terminal of finding interactive electric service instruction.
Background technology
Electron service instruction (ESG) is a very important one side in the application layer technology of mobile communication, the terminal use can utilize ESG to check data about miscellaneous service easily, browsing video channel, programme and price list etc., select and the purchasing price table in any content, and be linked to external web page and browse relevant information etc.
At present, have two kinds of ESG modes, a kind of is broadcast type ESG; Another kind is interactive ESG.In broadcast type ESG, terminal is carried out initialization by the bootstrapping session of broadcast type ESG, reads the tabulation of ESG provider and be shown to the terminal use from ESG discovery information; After the terminal use selected certain ESG provider, terminal was coordinated specific session according to the ESG visit information in the ESG bootstrapping session, the ESG data of the ESG provider that the receiving terminal user selects, as shown in Figure 1.
Among the interactive ESG of prior art, the terminal use can submit query requests, user profile information such as (User Profile) to server, has greatly enriched the function of ESG.
Interactive ESG uses Web service (Web Service) to realize.Web service is a kind of new Web page application program branch, and it can use the Internet protocol of standard, as HTTP(Hypertext Transport Protocol) and XML (extensible Markup Language) (XML), function is embodied in the Internet programmaticly and enterprises is online.Web service can be regarded as the component programming on the webpage.Web service be independently, modular application, it can describe, issue, locate and call by the internet.In the architectural framework of Web service, comprise three parts: service provider (Service Provider), service requester (Service Requestor), service logger (Service Registry).Three operations of main existence between each several part: issue (Publish), search (Find) and binding (Bind).
Web service itself has perfect discovery mechanism.Existing universal description, discovery and integrated (UDDI:Universal Description, Discovery, and Integration) standard are to finding under the condition of unknown of Web service place and using the method for Web service to be illustrated.UDDI can allow application discovery and contact that the server of given Web service is provided.After terminal and server end were introduced exchange channels, terminal can be submitted query requests to the UDDI server by exchange channels, obtained the Web service recalls information of specific ESG provider, and terminal can be called specific Web service according to the information that obtains afterwards.
Fig. 2 finds the flow chart of interactive ESG service for prior art.This flow process may further comprise the steps:
The Web service recalls information of the interactive ESG that step 204, terminal parses receive determines to submit to interactive ESG provider the form of request of data.
The form that step 205, terminal utilization are determined is submitted request of data to interactive ESG provider.
The shortcoming of this scheme is the bandwidth consumption instability, finds to the server end request that by exchange channels the load meeting of exchange channels increases under the situation of interactive ESG service simultaneously at a plurality of user terminals.Because a plurality of user terminal proposes the interactive ESG request of inquiry to the UDDI server simultaneously, the load meeting of UDDI server is heavier simultaneously.
In addition, different user terminals needs to download identical information from this interactive mode ESG provider respectively in order to find identical interactive ESG provider, therefore can reduce the service efficiency of exchange channels.
In the prior art, the technology that another kind obtains the Web service recalls information is Web service inspection (WS-Inspection) technology.Web service inspection technology relies on the distribution pattern on a kind of complete meaning that the information relevant with Web service is provided.Web service inspection technology collects in Web service with dissimilar ESG service describings and checks in the document, when terminal need find that interactive ESG serves, terminal directly checked that to there being Web service the service offering website of document sends the request of obtaining the Web service recalls information; The service offering website is checked document according to the Web service that the request inquiry that receives has self, and checks that according to Web service standard adopts existing standard to return the Web service recalls information to terminal.Described adoptable existing standard can be WSDL (WSDL, Web ServiceDescription Language) etc.; Like this, terminal can directly be used the Web service recalls information of obtaining, and does not need to carry out any modification.In the prior art, Web service checks that document adopts the XML form.
Thisly obtain the method for Web service recalls information, must therefore can increase the load of exchange channels, reduce the service efficiency of exchange channels by exchange channels from known service offering dot address download relevant information by the Web service inspection.
In sum, find in the prior art that the technical scheme of interactive ESG all needs to carry out between terminal and the server to obtain the recalls information of Web service alternately, therefore can cause the increase of exchange channels load, reduce the service efficiency of exchange channels.

Embodiment
For making purpose of the present invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
The core concept of the interactive ESG service method of the discovery that the embodiment of the invention provides, server end and terminal is: server end is handed down to terminal with the information relevant with finding interactive ESG service of ESG provider in broadcast channel; Terminal from broadcast channel, obtain ESG provider with find the relevant information of interactive ESG service.
The embodiment of the invention provides five kinds of schemes of finding interactive ESG service, in these five kinds of schemes in first kind, second kind and the 4th kind of scheme information relevant with finding interactive ESG service be: the Web service recalls information of interactive ESG, information relevant with finding interactive ESG service in the third scheme is: the inlet information of interactive ESG, the information relevant with finding interactive ESG service is in the 5th kind of scheme: the inlet information of the transmission session of the Web service recalls information of interactive ESG under the server end.
First kind of scheme of finding interactive ESG service that the embodiment of the invention provides is: server end is expanded the sign of the interactive ESG of identification in the discovery information of each provider, by broadcast channel each Web service recalls information is handed down to terminal as a connection object.When terminal has selected interactive ESG to serve definite user, obtain the Web service recalls information at broadcast channel.
Fig. 3 finds the flow chart of a preferred embodiment of interactive ESG method of servicing for the present invention, and this flow process comprises the steps:
Comprise the discovery information of a plurality of ESG provider in the ESG discovery information of server end, comprise in the ESG discovery information of each ESG provider: other satellite informations of numbering of the title of ESG provider, ESG provider (Provider ID) and ESG provider etc.
If ESG provider only supports interactive ESG service, or when only supporting broadcast type ESG service, server end expand interactive ESG and is identified in the discovery information of this ESG provider, and identifying this ESG is interactive mode or broadcast type ESG.
The visit information of each ESG provider of server end comprises: find numbering, the IP address that issues the ESG data and the port and the transmission session sign etc. of the ESG provider of associating information with ESG.
If ESG provider promptly supports interactive ESG, support broadcast type ESG again, then server end not only need be expanded interactive ESG sign in ESG discovery information, be used to represent that corresponding ESG service is interactive mode or broadcast type, also need in the ESG visit information, expand the sign of the inlet information of interactive ESG, be used for representing that corresponding ESG transmission session inlet information is to use or use at interactive ESG in broadcast type ESG.
Described transmission session can use agreements such as FLUTE as host-host protocol.Each Web service recalls information is broadcasted to terminal by transmission session as a connection object, in a transmission session, can be transmitted a connection object, also can transmit a plurality of connection objects.
If server end is broadcasted the corresponding Web service recalls information of a plurality of ESG services by a transmission session to terminal, then terminal only can't be determined the Web service recalls information of which connection object for self needing by the inlet information of this transmission session.
In the transmission session that issues interactive Web service recalls information, can obtain required Web service recalls information in order to make terminal fast definitely, server end can generate the index information of Web service recalls information in advance, and with this index information as one independently connection object in same transmission session, be broadcast to terminal with the Web service recalls information.
At least need to comprise following information in this index information: the numbering (Provider ID) of interactive ESG provider and connection object numbering, the connection object of a complete Web service recalls information of described connection object number-mark transmission.
Simultaneously, server end need be in the transmission session of transmission Web service recalls information, and what the sign connection object carried is index information or Web service recalls information.Like this, terminal is before receiving the Web service recalls information that self needs, identify the connection object of judging the carrying index information according to index information, therefrom read index information, and according to the numbering of the connection object at the required Web service recalls information place of the carrying of from index information, reading self, reading Web service recalls information in the corresponding connection object.The recalls information of the following stated all refers to the Web service recalls information.
Terminal can be obtained recalls information fast by using index information, be because recalls information is smaller usually, has only a hundreds of byte, therefore server end can be broadcast the cycle weak point of Web service recalls information by broadcast channel than wheel to the cycle of terminal carousel index information, and then makes terminal obtain needed Web service recalls information from broadcast channel rapidly and accurately.
Preferably, Web service recalls information WSDL standard to describe promptly uses wsdl document storage Web service recalls information.
Step 304 when ESG provider that terminal is selected according to the user determines to select interactive ESG, reads the session inlet information of the Web service recalls information that issues corresponding ESG provider from the ESG visit information of ESG bootstrapping session broadcasting.
This step comprises following process: the numbering of the ESG provider that the terminal recording user is selected; Can support interactive ESG if determine this ESG provider, and terminal is obtained the transmission session inlet information that issues the Web service recalls information when determining to select interactive ESG according to provider's numbering of record from the ESG visit information.
Here, terminal can determine whether this ESG provider can provide interactive ESG according to the interactive ESG sign in the ESG discovery information of numbering correspondence of the ESG provider of record, if can, then terminal can determine that selecting interactive ESG method of service still is broadcast type ESG method of service according to the information such as power of whether having opened exchange channels service or exchange channels signal.
If only transmit the connection object of a Web service recalls information in described transmission session, then terminal can directly be obtained the Web service recalls information from this transmission session;
If the connection object of the connection object of a plurality of Web service recalls information of transmission and encapsulation index information in the described transmission session, then terminal identifies the connection object of judging the carrying index information according to index information, therefrom read index information, and according to the numbering of the connection object at the required Web service recalls information place of the carrying of from index information, reading self, reading Web service recalls information in the corresponding connection object.
The Web service recalls information that step 307, terminal parses are obtained obtains to call the required information of Web service of interactive ESG service.
Above step has realized finding the purpose of ESG service, after terminal gets access to the Web service recalls information, carry out following steps and obtain the ESG data that meet oneself requirement from interactive ESG provider: terminal is submitted request of data by exchange channels to interactive ESG provider; Interactive mode ESG provider handles the request of data that receives, and generates result data; Interactive mode ESG provider returns the ESG data that meet the terminal data request by exchange channels.
Fig. 4 is the flow chart of a kind of implementation embodiment illustrated in fig. 3.The provider of the needed ESG service of setting terminal only supports interactive ESG or only supports broadcast type ESG in this implementation, and server end is broadcasted a plurality of Web service recalls information to terminal in a transmission session connection object, setting the Web service recalls information is wsdl document, transmission session is the FLUTE session, and this flow process comprises the steps:
In the prior art, ESG finds information by the carrying of ESGProviderDiscovery descriptor, and the ESG visit information is carried by the ESGAccessDescriptor descriptor.
In the ESGProviderDiscovery descriptor, each ESG provider is described by service provider's element, and the type of this element is ESGProviderType.In order to allow terminal can judge that an ESG service is interactive mode or broadcast type, the present invention has expanded a field in ESGProviderType, be used to represent that corresponding ESG service is interactive mode or broadcast type, with this field called after InteractiveESG sign, as shown in table 1.All elements was the ground floor element of ESGProviderType during type E1 represented in table 1.
Table 1
Server end is expanded interactive ESG sign in the discovery information of each ESG provider, can also be used as interactive ESG sign position by in the title ProviderID of provider of each ESG provider field, taking out a bit, be used to represent that corresponding ESG service is interactive mode or broadcast type.
The structure of the index information of the wsdl document connection object that transmits in transmission session is as shown in table 2.Comprise in this index information: the number of wsdl document, the numbering of interactive ESG provider and the numbering of each connection object.The data type of each field all is signless integer, high priority.
| Grammer | Field length (bit) | Implication |
| WSDL_index{ | Index structure | |
| num_of_WSDL | 8 | The number of wsdl document |
| for(i＝0；i＜num_of_WSDL；i++){ | ||
| providerID | 8 | The numbering of interactive mode ESG provider |
| TOI | 32 | The connection object numbering |
| } | ||
| } |
Table 2
In the FDT-Instance of FLUTE agreement XML Schema, root element FDT-Instance comprises a plurality of File elements, and each File element is described a connection object.Each File element comprises the anyAttribute attribute that can expand arbitrarily.
If the transmission of connection object is wsdl document, the anyAttribute attribute of the File element of this connection object of extended description not then; If a connection object transmission is index information, then the anyAttribute attribute of the File element of this connection object of extended description.
For the connection object of transmission index information, the anyAttribute attribute of the File element of correspondence is expanded to: InteractiveESGIndex=Ture.
Fig. 5 is handed down to wsdl document the schematic diagram of terminal by a transmission session for mode shown in Figure 4.As seen from the figure, index information is handed down to terminal as an independent connection object, and this connection object is by the FDT attribute InteractiveESGIndex sign of expansion.
When step 405, terminal are determined to select broadcast type ESG according to provider's numbering of record, according to the specification handles of broadcast type ESG, process ends; When determine selecting interactive ESG, execution in step 406.
Here, terminal can determine to select broadcast type ESG, still interactive ESG according to the interactive ESG sign in the ESG provider discovery information.
Step 408, terminal receive the connection object that has extended attribute InteractiveESGIndex in the described transmission session of step 407, therefrom read index information.
Step 409, terminal read from index information and the corresponding connection object numbering of provider's numbering.
Step 410, terminal are obtained from transmission session and the consistent connection object of connection object numbering that reads, thereby obtain required wsdl document.
Fig. 6 is the flow chart of another kind of implementation embodiment illustrated in fig. 3.The provider of the needed ESG service of setting terminal promptly supports interactive ESG in this implementation, support broadcast type ESG again, and server end is broadcasted a plurality of Web service recalls information to terminal in a transmission session connection object, setting the Web service recalls information is wsdl document, transmission session is the FLUTE session, and this flow process comprises the steps:
Server end adopts the mode shown in the table 1 to expand interactive ESG sign in ESGProviderType, mode shown in the employing table 2 is constructed index information, and the anyAttribute attribute of spread F ile element, i.e. InteractiveESGIndex=True in the connection object of the method transmission index information that employing is identical with implementation shown in Figure 4.
Simultaneously, this implementation is AccessMethod field of expansion in ESGAccessDescriptor also, and the transmission session inlet information that is used for distinguishing two identical visit informations of provider's numbering is that interactive ESG uses or broadcast type ESG uses.In this implementation, from reserved field, take out a bit as the AccessMethod flag bit, reserved field is reduced to 5 bits from 6 original bits.
Shown in table 3 and table 4, table 3 is the structure of ESGAccessDescriptor; Table 4 is an expansion AccessMethod field in ESGEntry.
Table 3
Table 4
When step 605, terminal are determined to select broadcast type ESG according to provider's numbering of record, according to the specification handles of broadcast type, process ends; When determine selecting interactive ESG, execution in step 606.
Here, terminal can determine that selecting interactive ESG method of service still is broadcast type ESG method of service according to the information such as power of whether having opened exchange channels service or exchange channels signal.
Step 608, terminal receive the connection object that has extended attribute InteractiveESGIndex in transmission session, therefrom read index information.
Step 609, terminal read from index information and the corresponding connection object numbering of provider's numbering.
Step 610, terminal are obtained from transmission session and the consistent connection object of connection object numbering that reads, thereby obtain required wsdl document.
Second kind of scheme of finding the ESG service that the embodiment of the invention provides is: with container encloses recalls information file, each container is broadcast to terminal as a connection object by broadcast channel in transmission session.Each container can encapsulate one or more minor structures, each Web service recalls information file of minor structure encapsulation or index information file.
If only encapsulate a minor structure in the container, promptly only encapsulate a Web service recalls information file, and in a transmission session, only transmit a container, then do not need to construct index file; If a plurality of minor structures of container encloses or/and transmit a plurality of containers in a transmission session, then need to construct the index information file, each Web service recalls information file of minor structure encapsulation or index information file.In transmission session, each container is by unique container number sign, and in each container, each minor structure is by unique minor structure number-mark.
Fig. 7 finds the flow chart of second preferred embodiment of interactive ESG method of servicing for the present invention.This flow process may further comprise the steps:
A container can only encapsulate a recalls information, also can encapsulate a plurality of recalls information.If a plurality of recalls information of encapsulation in a container, each recalls information is encapsulated in the minor structure of container.The management information of container is included in the head construction of container.Vessel head need comprise following information: the file type of minor structure encapsulation; The numbering of minor structure, this label is unique in a container; The original position of the file of minor structure encapsulation; The length of the file of minor structure encapsulation; The version information of the file of minor structure encapsulation.
When encapsulating a plurality of recalls information in the container, for locating the container and the minor structure at Web service recalls information place fast, server end generates the index information of recalls information, and index information is encapsulated in one independently in the container, in transmission session and recalls information be handed down to terminal together.
At least need to comprise following information in the index information: the numbering of interactive ESG provider; The container number at recalls information file place; The minor structure numbering at recalls information file place.The index information file is encapsulated in separately can guarantees in the container that index information place container is enough little, thereby make terminal can read index information fast.
If ESG provider promptly supports interactive ESG, support broadcast type ESG again, then server end not only need be expanded the sign of interactive ESG in ESG discovery information, be used to represent that corresponding ESG service is interactive mode or broadcast type, also need in the ESG visit information, expand the sign of the transmission session inlet information of interactive ESG, be used for representing that corresponding ESG transmission session inlet information is to use or use at interactive ESG in broadcast type ESG.
If the container of encapsulation index information is arranged, the container that then will encapsulate index information is broadcasted to terminal as an independent connection object.
When step 705, terminal are determined to select interactive ESG according to provider's numbering of record, execution in step 706; When if terminal determine to be selected broadcast type ESG, then according to the broadcast type specification handles of prior art, process ends.
Here, terminal can determine whether this ESG provider can provide interactive ESG according to the interactive ESG sign in the ESG discovery information of numbering correspondence of the ESG provider of record, if can, then terminal can determine that selecting interactive ESG method of service still is broadcast type ESG method of service according to the information such as power of whether having opened exchange channels service or exchange channels signal.
If encapsulated a plurality of Web service recalls information in a container, and server will encapsulate index information in transmission session container is handed down to terminal, and then end step 708 comprises following process:
Terminal encapsulates the container of index information according to the vessel head information Recognition, and reads the index information of recalls information file in the transmission session; Terminal obtains corresponding container number and minor structure numbering according to provider's numbering of record from the index information that reads; Terminal is obtained the container that is packaged with required recalls information according to the container number that obtains in transmission session, according to the minor structure numbering that obtains, obtain required Web service recalls information from this container again.
Fig. 8 is the flow chart of a kind of implementation embodiment illustrated in fig. 7, and recalls information is promptly used the discovery and the recalls information of wsdl document storage Web service by the WSDL standard to describe in this implementation, and sets a plurality of wsdl documents of encapsulation in the container.Host-host protocol uses FLUTE.This flow process comprises the steps:
If ESG provider only supports interactive ESG, or only support broadcast type ESG, then server end adopts the mode shown in the table 1 to expand interactive ESG sign in the ESG of each ESG provider discovery information; If ESG provider promptly supports interactive ESG, support broadcast type ESG again, then server end not only needs the mode shown in the employing table 1 to expand interactive ESG sign in the ESG of each ESG provider discovery information; Also need the mode shown in the employing table 2 in the ESG of each ESG provider visit information, to expand the sign of the transmission session inlet information of interactive ESG.
Server end is encapsulated in wsdl document in the container, and the structure of container can be shown in table 5 and table 6, and the data type of each field all is signless integer, high priority (uimsbf, i.e. unsignedinteger, most significant bit first).Table 5 is the structure of container, and table 6 is the span of structure_type field and implication in the container shown in the table 5.
In transmission session, each container transmits as a connection object, is described by a File element among the FDT-Instance.Each container of content_location attribute unique identification in the File element has wherein comprised the numbering of container; The content_type attribute shows the type of the content of carrying in the container.
Table 5
| Value | Implication |
| 0x01 | Wsdl document (WSDL File) |
| 0x02 | WSDL index (WSDL_index) |
| Other | Keep |
Table 6
For locating the container and the minor structure at Web service recalls information file place, the index information shown in the definition list 7 fast.The data type of each field all is signless integer, high priority (uimsbf, i.e. unsigned integer, most significant bit first) in the table 7.Index information is encapsulated in separately can guarantees in the container that index information place container is enough little, thereby make terminal can read index information fast.
As seen from Table 7, comprise following information in the container of index information of encapsulation wsdl document: numbering, the carrying of the number of the wsdl document of this container carrying, interactive ESG provider describe the container number of the wsdl document of this interactive mode ESG, the minor structure numbering of carrying wsdl document in container.The index information file is encapsulated in separately can guarantees in the container that index information place container is enough little, thereby make terminal can read index information fast.
Table 7
In order to identify the container of encapsulation index information, need at the internet numbering mandate (IANA of the committee, Internet Assigned Number Authority) new content type: urn:dvb:wsdlcontainer of application definition in the normal structure, and the content_location connection object of describing the File element of this container is numbered the n attribute and is set to urn:dvb:wsdlcontainer:cid:1.In addition, the content_type attribute of all containers is set to applicaton/vnd.dvb.wsdlcontainer.
Referring to Fig. 9, Fig. 9 is for broadcasting the schematic diagram of a plurality of containers to terminal by a transmission session.Among the interactive ESG shown in this schematic diagram, comprised a plurality of containers, one of them container has only comprised vessel head and index information, comprises the wsdl document of vessel head and a plurality of Web service recalls information in other the container.
When step 805, terminal are determined to select interactive ESG according to provider's numbering of record, execution in step 806; When terminal is determined to select broadcast type ESG, according to the broadcast type specification handles of prior art, process ends.
If ESG provider only provides interactive ESG service, then terminal is obtained the IP address and the port numbers of the transmission session that issues wsdl document from the ESG visit information according to provider's numbering of record;
If ESG provider not only can provide interactive ESG service, broadcast type ESG also can be provided service, then terminal is according to the provider numbering of record, the ESG mode of selecting, and the AccessMethod field in the ESG visit information is obtained the IP address and the port numbers of the transmission session that issues wsdl document from the ESG visit information.
This programme is encapsulated into the recalls information file in the container, is easy to server end and manages.Issue the recalls information file of interactive ESG by broadcast channel, avoid the terminal to server end to submit query requests to, the bandwidth of effectively saving exchange channels, provider need not to provide the interactive ESG service-seeking server of specialty, has saved operation cost.
The third scheme of finding the ESG service that the embodiment of the invention provides is: server end is preserved interactive ESG in the discovery information of each ESG provider or visit information inlet information.Because interactive ESG provides service by Web service, so the inlet information of interactive ESG can be the URL(uniform resource locator) (URL) of Web service.
When the ESG provider that terminal is selected according to the user determines to select interactive ESG to serve, from ESG discovery information or visit information, obtain the inlet information of this interactive mode ESG service, and according to this inlet information acquisition Web service recalls information.
Figure 10 finds the flow chart of the 3rd preferred embodiment of interactive ESG method of servicing for the present invention.This flow process may further comprise the steps:
Present embodiment provides two kinds of concrete inlet information of preserving interactive ESG in ESG discovery information, and the inlet information of interactive ESG is the mode of the URL of Web service here:
First kind of mode is: server end is expanded interactive ESG sign in ESG discovery information, preserve the URL of Web service simultaneously in the discovery information of ESG provider.
If server end is saved in the URL of Web service in the ESG discovery information, then in ESG discovery information, will comprise the discovery information that two providers number identical ESG provider.The discovery information of these two ESG providers can identify by the interactive ESG of expansion in ESG discovery information and distinguish.
Preferably, adopt the method shown in the table 1 in the ESG of each ESG provider discovery information, to expand interactive ESG sign.Simultaneously, the URL of Web service can be kept in the ProviderinformationURL element among the ESGProviderType shown in the table 1.
The second way is: newly-increased InteractiveESGURL element in the ESGProviderType of the ESG of ESG provider discovery information, if that corresponding ServiceProvider element is described is interactive ESG, the inlet information of the interactive ESG of the value representation of this element then; Otherwise the value of this element is empty.As shown in table 8 is the mode of the second kind of interactive ESG inlet of expansion information:
Table 8
Present embodiment also provides two kinds of concrete modes of preserving interactive ESG inlet information in the ESG visit information:
First kind of mode is: as shown in table 9, Accesstype represents ESG entry address type in the ESG visit information, promptly interactive ESG sign.When this field is 1, expression broadcast type ESG; When this field is 2, represent interactive ESG.In table 9, also increased the field URL of the entry address of representing interactive ESG, and the length field URL_Length that represents the entry address of interactive ESG.
