In response to receiving, can provide the node of this information can take action so that abide by this request to the available set request-related information.Therefore, this node can return the message that comprises adequate information to user's node.With regard to each group, described adequate information for example can comprise the metadata corresponding to this group.Described metadata for example can comprise the title of group, the description of group, the indication of group membership criterion and/or relate to some individual contact details relevant with this group.Described individuality can be the individual that the keeper of for example these groups and/or can permit enters needs the group that application just can enter.
Under the customer-furnished situation of metadata, node can provide the relevant information of group that the metadata that provides only is provided with its associated metadata.Attention in each embodiment, corresponding to a certain group metadata comprise the membership qualification criterion and/or with group application (group application) the relevant information to be finished in order to ask group membership.As an object lesson, can there be three kinds of group applications (for example short-term, criterion and long-term), metadata can be informed and will be adopted any in these the three kinds group applications.To discuss the group application below in more detail.Attention is in each embodiment, and in the process that the information that only relates to appropriate group is provided, node can be carried out various operations, and described operation relates to metadata analysis, text analyzing and/or contrasts the conversion of the keyword of some metadata fields.Described some metadata fields can be to be defined as and/or to be designated as maximally related those metadata fields.Such indication can be waited by the system manager and finish.
Can send according to multiple mode in response to message the available set request-related information.For example, can be by Email, MMS information receiving, SMS information receiving, OBEX OPP, the information receiving by the network that formed by node waits this information that sends.The information receiving of the network that forms via node can be via peer link, perhaps by direct link (but when time spent).Such action can user node the network address etc. be target.Such network addresss etc. are received by the request to group information.
Attention is not sent under the situation of corresponding requests at user's node in each embodiment, and user's node can receive this message that comprises group information.For example, the member of group and/or the keeper of group can be sent out such information not clearly under the situation of request.Can under the purpose that increases group membership's number, carry out such action.In each embodiment, such message can comprise the invitation of adding group, and described invitation perhaps is included in and does not require that the user carries out under the situation of any specific action the software module and/or the description of the suitable software module in the excited users node etc.The interface that the action of user's adding group can be provided by its node by the user, the invitation of accepting to send replenishes complete.As a concrete non-limitative example, invitation can be that the recreation that game application shows is invited, and the user can accept this invitation by the interface relevant with game application.
In each embodiment, one type group can be one group of user's oneself a node, and a described group node is used to realize shared file, upload file, search file and/or file in download between these terminals.In such group, user's node can carry out the comparison of group membership metadata of other user's node.According to this relatively, can belong to, but those groups that other node does not belong to form a tabulation by some nodes in the user node.This tabulation can be used to make group membership synchronous among user's terminal, in order to start more group of application request, perhaps requires user's affirmation.The another kind of mode of the group membership of management specific user's node comprises that the user who sends application entrusts to a node with administrative power, so that this node can further be authorized group membership to other node of this user subsequently.
After receiving group information, in each embodiment, user's node can present group information (step 105) to its user by GUI or other interface.GUI or other interface allow the user to represent to add one or more groups the hope that its information is presented.Respond its user and make such selection, user's node can send the message (step 107) that joins request to appropriate target.Described appropriate target can coexist receive relate to the same of appointment in selected group the contact details.In each embodiment,, and/or can be included in the message that joins request corresponding to one or more unique identifiers of one or more groups corresponding to one or more unique identifiers of described user.
According to top described similar mode, the message that joins request can be passed through Email, MMS information receiving, SMS information receiving, OBEX OPP, is sent out through the information receiving of the network that formed by node etc., is directed according to the reception contact details of correspondence.The information receiving of the network that forms by node can be via peer link, perhaps by direct link (but when time spent).
When receiving at appropriate node when joining request message, in each embodiment, described appropriate node inserts relevant metadata catalog, warehouse etc., so that consult the group rule.In each embodiment, this group of rule can be by foundation such as Group administrators.In each embodiment, the service provider can serve as one or more groups Group administrators.In such embodiments, the software module of one or more nodes that manipulation is relevant with the service provider allows the service provider member in these groups to be confined to its client.Just consult the group rule, node is at first understood and whether may be answered this for certain and join request.As an object lesson, can consult group rule, whether to exist in the system of solutions and be used for more members' place arbitrarily.
The further processing that joins request can take place automatically by the software module of appropriate node.Another kind of situation is the GUI of described appropriate node by node, the notice that joins request that receives is had the right to ratify the Group administrators of group membership etc.
Described appropriate node or Group administrators also can consult some external data bases or register, become member etc. so that whether understanding has qualification corresponding to the user who joins request.Such qualification comprises that the user is relevant with a certain area, represents a certain interest group, the evidence of the membership qualification in the club etc. and/or can share public secret as the group membership criterion.In each embodiment, can joining request and/or according to the user data in the membership qualification application, received this consulting taken place afterwards according to the user.
Determining that the user can not be granted under the situation of membership qualification, can send refuse information to user's node.According to top described similar mode, can be by Email, MMS information receiving, SMS information receiving, OBEX OPP, through the described refuse information of transmission such as information receiving of the network that forms by node.The information receiving of the network that forms by node can be via peer link, perhaps by direct link (but when time spent).Finding that the user may be granted under the situation of membership qualification, can further consult the group rule, to understand in order to ask membership qualification, whether the user must fill in the group application form.
Under the situation that does not need this application form, the user can be given membership qualification.Therefore, can send the message that indication has given membership qualification.According to top described similar mode, can be by Email, MMS information receiving, SMS information receiving, OBEX OPP, through the described message of transmission such as information receiving of the network that forms by node.The information receiving of the network that forms by node can be via peer link, perhaps by direct link (but when time spent).In each embodiment, the certificate corresponding with group membership is included in the described message.
Application form if desired can be sent to the user's who seeks membership qualification node so corresponding to the data of application form.According to top described similar mode, for example as the refuse information that joins request that sends, can be by the network that forms by node, Email, the MMS information receiving, the SMS information receiving, OBEX OPP etc. send described message.The information receiving of the network that forms by node can be via peer link, perhaps by direct link (but when time spent).Attention is in each embodiment, and described application form needs charging information (for example credit card information).
Data corresponding to application form can be taked various ways.For example, described data can be taked the form of the hyperlink of security website, and described security website can provide described application form, and the result is transmitted to the node that sends message, and described message comprises the data corresponding with application form.Described security website can adopt SSL (security socket layer) or TLS (Transport Layer Security).As another example, described data can be taked the form of Java or .Net application program, and when the node operation the recipient, Java or .Net application program can provide described application form, and the result is transmitted to the node that sends message, described message comprises the data corresponding with application form.In either case, according to top described similar mode, result's forwarding can be adopted Email, the MMS information receiving, the SMS information receiving, OBEX OPP is through the information receiving of the network that formed by node etc.The information receiving of the network that forms by node can be via peer link, perhaps by direct link (but when time spent).As a kind of alternative, can adopt SOAP (simple object access protocol), RMI (RMI), JMS (service of Java information receiving) etc.
When receive forwarding as a result the time, receiving node can check that those rules whether described result need with granting group membership are consistent.Thisly determine to comprise more described result and above mentioned group of rule.On the other hand or in addition, this determine to comprise with one or more servers etc. communicate by letter the desired account data of application form for confirmation etc.Described one or more server can be the server by operations such as bank, credit card companies.Determining and giving under the situation of membership qualification to the user, can send refuse information as mentioned above like that.If determine to give membership qualification, can send the message that the indication membership qualification has been granted so as mentioned above like that.
Attention in each embodiment, corresponding to the user can be the metadata of the classification as mentioned above of for example collecting by the customer representative, and/or with group in the relevant metadata of user's membership qualification.In each embodiment, the metadata of last classification can be shared between all user nodes, may not be by user's modification, and then the metadata of a classification has only when user's regulation and just can be shared.

In each embodiment of the present invention, the network operation that the user carries out may cause producing expense, for example Internet utilization fee with another family.Under the certain situation of user's request by the entity of one or more users' node transmission, that's how things stand.Therefore, in each embodiment, can provide such function,, can inform to the user and carry out in the particular network operation expense that she can cause other user to bear by this function.Can be according to so notifying the user with described similar mode just.
In response, node can provide this user tabulation for one of member's group to its user, and requires her to point out to tackle in these groups which to search for.The user can be by GUI or other interface make a choice (step 203).As next step, in each embodiment of the present invention, the user can select to point out and entity metadata corresponding keyword and/or other parameter (step 205) that should be searched to its node.According to some embodiments of the present invention, can specify various metadata.For some concrete non-limitative examples are provided, notice that assignable metadata can be with group and the metadata that group service is relevant such as chat, the metadata of being correlated with the entity of search, such as validity date of title, size, type, artist, photo book, medium type, date created, group etc.In certain embodiments, the user can stipulate regularly to search for.The frequency of periodic search can and/or can be specified by the user by the node selection.In addition, in some embodiments of the invention, the user can specify the time and date that should begin to search for.In addition, in each embodiment, can be specified to the user with the relevant operation of search and on this node, not carry out interactive the time with node.As another example, in each embodiment, search operation can be specified to and always be in active state.Form that can background process is carried out the operation relevant with this search, appropriate user interface software module inertia consequently, and the user does not initiatively carry out any effort.
In each embodiment, the communication port of user's node by having set up sends one or more message subsequently, and described one or more message comprise the information of the downloaded entity corresponding with the one or more nodes that belong to selected group.
Subsequently, user's node is about one or more groups of selection, and any standard of metadata and/or other parameter, and determining can be for the entity of downloading.Can realize this function according to multiple mode.
For example, user's node can send one or more message by the communication port of having set up subsequently, and described one or more message request relate to the information of the entity downloaded of the one or more nodes that belong to selected group.Do not have the communication port that is enough to arrive the enough nodes in selected group if user's node is noticed, node can adopt service discovery so, perhaps is that above-mentioned the sort of service discovery is learned the node that is associated with designated groups.Therefore, by such service discovery, user's node can be learned the network address corresponding with these nodes etc.User's node sends one or more message subsequently, one or more node requests with the entity that can the download relevant information of described one or more message in these nodes.Be included in the described request can be the Any user standard of metadata and/or other parameter.According to top described similar mode, can be by Email, MMS information receiving, SMS information receiving, OBEX OPP, the network that forms by node sends scheduling message etc. and sends each such message.The information receiving of the network that forms by node can be via peer link, perhaps via direct link (but when time spent).
As next step, these nodes can provide the information relevant with the entity that can download to user's node, and/or request being sent to other node in the group according to the mode of describing in the U.S. Patent application of pending trial " System and Method forMessage Handling in a Peer-To-Peer Environment " at the same time, this patent application is drawn at this and is reference.
Subsequently, user's node can receive the information (step 207) relevant with the entity that can download.In each embodiment, such information can comprise relevant unique identifier, the network address etc.Such information can arrive according to multiple mode.For example, according to top described similar mode, by by Email, MMS information receiving, SMS information receiving, OBEXOPP, the message that the information receiving of the network that forms via node etc. sends arrives in such information.The information receiving of the network that forms via node can be via peer link, perhaps via direct link (but when time spent).Comprise in the information that receives can be for example with the entity metadata corresponding that can download and/or other parameter.For example also can comprise in addition and the number that receives corresponding network trunk section at the entity of user node, the type of network trunk section, Internet utilization fee is with the indication of information etc.
Subsequently, node can pass through GUI or other interface, presents whole or some the reception information (step 209) that relate to the entity that can download to its user.Provide among each embodiment of link and/or interface operating specification the user, described presenting can be according to described standard.As an object lesson, the expression that is provided with in user or user node minimizes the use of the cellular link such as GPRS or UMTS link, and make under the situation of the maximized hope of use of the short-distance wireless communication link such as Bluetooth link, node can only provide the information relevant with the entity that can fetch according to these standards.Attention can be asked more Search Results in each embodiment.For such embodiment, GUI or other interface can provide the right to choose of this further search of request to the user.Ask the user under the situation of this further search, user's node can be taken action as mentioned above like that, so that abide by this request.When receive further search as a result the time, user's node can according to described similar mode just, present all or some receive data, and perhaps provide the right to choose of further search once more.The phase I Search Results presents can comprise the substitute relevant with content item, such as the thumbnail of image, and the sample of video clipping, documentation summary etc.In certain embodiments, Search Results may show metadata and other description of the entity that finds, the identity of holding the node of this entity, and owing to this node is not in active state or can not arrives this node, the unavailable additional notifications of project itself this moment.
In each embodiment, GUI or other interface also allow the user to select from the entity that presents for the one or more entities (step 211) that receive.User's node can be according to the reception of the selected entity of multiple mode request.For example, user's node can be by Email, MMS information receiving, SMS information receiving, OBEX OPP, and the information receiving by the network that formed by node etc. sends one or more this requests.Described request can with the unique identifier of the node that required entity is provided, the network addresss etc. are target.By about available entity inspection by Email, MMS information receiving, SMS information receiving, OBEX OPP, the message that the information receiving by the network that formed by node etc. receives can be known described unique identifier, the network address etc.As an object lesson, can obtain described knowledge by sending and receive search and searching for response message.Attention can perhaps can be passed through direct link (but when time spent) via peer link via the information receiving of the network that node forms.
As next step, user's node can receive the entity of request.Can the entity of request be sent to user's node according to multiple mode.For example, entity can be by the node that has them by Email, MMS information receiving, SMS information receiving, OBEX OPP, and the information receiving that passes through the network that is formed by node waits and sends.The information receiving of the network that the process node forms can be via peer link, perhaps by direct link (but when time spent).In each embodiment, just select for the entity of downloading, the user can represent the hope of having ready conditions and downloading.For example, the user can stipulate to have only when her node can be contacted directly the node (for example by direct Bluetooth communication) of holding special entity, and this entity just can be downloaded.
User's node can be deferred to such request according to multiple mode.For example, know that at user's node user's node can regularly carry out device discovery, attempts to search the node of holding this entity, and when the node of holding this entity is found, described entity is received under the situation of identity of the node of holding entity.As another example, if not indicating by the single network hop, Search Results can not receive entity from node, user's node can regularly repeat described search so, till finding such result, operates subsequently so that the single hop source receiving entity by finding.As an object lesson, user's node can carry out such search, so that find to relate to the entity source of single bluetooth hop.In another alternative,, can start entities loading so in case exist from user node to providing bluetooth to connect to other node of the access of the node of holding entity.
According to each embodiment, just to select for the entity of downloading, user and/or user's node can stipulate that the different piece of entity receives according to different modes.For example, point out that to the user specific entity can receive according to dual mode at node, a kind of mode only relates to the bluetooth hop, when the second way only relates to the UMTS hop, the user can should receive by the UMTS hop by the first of GUI or other interface regulation entity, and the remainder of entity should receive by the bluetooth hop.In each embodiment, user and/or user's node also can be stipulated the size of various piece.Therefore, user and/or user's node can stipulate that first is with the appointment of byte representation size and/or is the part of whole appointment.For example, first can be significantly less than remainder.Thinking that but bluetooth is slow cheap, UMTS is very fast but more expensive, and adopt she be ready to bear obtain first cost (for example, so that she can bring into use this entity), but be ready to wait for that the longer time receives under the situation of viewpoint of remainder, user and/or user's node is made such standard.
As an object lesson, can select the each several part size, so that when the user had utilized the first of entity, other parts ought to arrive.Note entity, can be provided in such as the media item that is similar to sound, film etc. and do not handle under the whole situation, can check the function of the part of this entity.
In each embodiment, the repeating transmission that is received the entity of (for example result from network error) fully can be such, so that correct each entity part that receives is not sent once more.
Under the situation that the different piece of user's node rather than user's regulation entity should receive according to different modes, this function can be consistent with operating guidance.Described guide can be based on the preferential selection of user (for example by GUI) setting and/or based on default setting.Default setting can be placed on the node being loaded on the node during the initial setting up and/or (for example transmitting by the network of proper data) sometime afterwards.In each embodiment, default setting can be by the service provider, and system manager etc. provide.
In each embodiment, the node regulation can be carried out by one or more software modules of moving on node according to the function of the different piece of different mode receiving entities.Be also noted that under the purpose that obtains efficient communication this function can be the part of the repertoire of node realization.Be also noted that the interruption of the availability of interruption that node can connect according to tolerance and/or various links, created again when connecting, but and/or one or more Linktype become the time spent once more, perhaps can easily recover the mode of network operation and take action.
In addition, though the explanation user can handle various settings in the various piece here, in each embodiment, the user may not need to handle such setting.For example, attention can be provided for one group of default setting of her node to the user in each embodiment, described one group of default setting provides acceptable operation, if consequently the user loses interest in to handling to be provided with, the function that is provided by its node described herein still can be provided for she so.Such default setting can be during fabrication and/or is offered her node during initial registration.Be also noted that in each embodiment when the user had its node first, the user can set setting, upgrade these settings subsequently termly and/or of one's own accord.
Be also noted that in each embodiment, utilizing before its node carries out other operation, the user needn't wait for diverse network described herein operation (for example relevant operation, relevant operation with search with the adding group, with share relevant operation, relevant operation and the operation of being correlated with information receiving with chat) finish.Therefore, when for example carrying out one or more network operation described herein with the form of background process, the user can transfer to another part of the application program of moving on its node, perhaps transfer to the Another Application program, carries out another network operation etc.In each embodiment, the user can receive and/or ask state and/or the end notification as one or more this network operations of background process.Can provide such state and/or notice according to non-conflicting mode (for example by the presenting of small icon, described icon perhaps is associated with status bar etc.).
Sharing operation
Referring to Fig. 3, attention is according to each embodiment of the present invention, wishes to make the user that can be received by other node from the entity such as file, media item, program, file (for example comprising a plurality of entities) of its node at first to represent the hope (step 301) done like this by GUI or other user interface.In response, her node can allow the user to select one or more entities that will make it available.Can provide this function according to multiple mode.For example, can allow the user to browse the file system of node, and select those entities (step 303) that to share by GUI or other interface.
Subsequently, for the entity of each selection, in each embodiment, which group node can download the inquiry user for about making this entity.For example, node can provide corresponding GUI check box or the analog of downloading for one of member's permission with this user (step 305) of each group for each entity.For the entity of each selection, in each embodiment, node can point out the user to import metadata corresponding and/or other parameter (step 307) in addition.In certain embodiments, node determine metadata and/or other parameter with situation that a certain project is associated under, node can not carry out such operation.In each embodiment, the metadata that is associated with entity and/or other parameter can comprise unique identifier.Therefore, node is created the unique identifier corresponding with the entity of each selection subsequently, and it is attached on the metadata of this entity.Can create unique identifier according to multiple mode.For example, in described establishment, can adopt random number to take place and/or one or more equation.
In each embodiment, node is subsequently with the physical replication the selected one or more suitable file to the node relevant with file-sharing.In another embodiment, replace duplicating the entity of selection itself, can duplicate link entity (for example file), and/or perhaps metadata corresponding and/or out of Memory.For example, node can be one of member to its user, and each group that entity can be downloaded keeps such file.As next step, the operation (step 309) that node can make the entity of selection download.Can realize this function according to multiple mode.
In addition, in each embodiment, node can be carried out appropriate operation, finds the project that it will be provided for downloading to allow top described the sort of service discovery operation.In addition, node can carry out suitable operation, so that according to top described, makes it oneself prepare the message that response request relates to the information that can download entity.As mentioned above, can pass through this message of reception such as information receiving of the network that forms by node by Email, MMS information receiving, SMS information receiving, OBEX OPP.The information receiving of the network that the process node forms can perhaps pass through direct link (but when time spent) via peer link.
In each embodiment, node can receiving entity or entity part, so that send it to another node, such entity or entity part can with unique identifier together by cache, and can further download by other node that belongs to any peer-group.Be otherwise noted that node can the basis standard relevant with free memory, determine whether to carry out such cache.Be otherwise noted that in each embodiment, can provide entity or entity part by multicast (if this function is suitable).
Be also noted that in each embodiment the user can refuse to arrive the searching request and/or the project reception request of its node.The user can make such standard by gui interface or other interface that its node provides.Can provide various forms of this functions to the user.For example, the user can stipulate that all search and/or project request should be rejected.As another example, the user can stipulate to be rejected with all search and/or the project request of designated parameter coupling.As another example, the user can stipulate that its node notifies each search of coming and/or project request to her, and is provided and allows or the right to choose of rejecting said request.In each embodiment, in the process of the request of coming to her notice, user's node can provide the information of varying number and type to her.
In each embodiment, by the interface of user node, can define in case a certain entity is marked as and will be shared, entity is shared and will how to be taken place.For example, wish to avoid the user of extra charge relevant and/or the use of excess processes device, electric energy use, bandwidth use etc. can stipulate that the uploading of metadata that should make file and/or describe these files minimizes with the use of the access link of its node.Can utilize the various combination of optimisation technique.
As an object lesson, entity is marked as and will be shared, and in each embodiment, the copy of the metadata of entity and/or entity itself can be transmitted to and belong to other node of appropriate group.These nodes can be other user node or service provider's nodes for example.The advantage of this operation be user node and/or appropriate software module always be not in active state and/or situation about can get in touch under, improved shared entity and/or about the availability of the information of sharing entity.As another example, this operation has under the situation that the user does not allow to search for and/or download request is satisfied by her node, can realize the advantage of sharing.
In each embodiment, send the copy of the metadata of entity and/or entity itself to other node and also can consider shared relevant expense and bandwidth problem with data.Can consider these problems (for example, wherein node is placed with located adjacent one another) by between node, send data via short-range wireless link.
In another example, in case node is received searching request, so in each embodiment, this node can determine whether it has the entity of being asked and/or corresponding to the entity of being asked, perhaps with any other entity of institute's request entity close match.Afterwards in each embodiment, this node can send search and reply, and the description metadata that will describe entity joins during this replys.In each embodiment, metadata or its part comprise the unique identifier and/or the network address of node, and/or the unique identifier of entity itself is copied to search is replied in the cache memory of the intermediate node that sends requesting node to.The actual search that sends requesting node to is replied the subclass that may only comprise the metadata description of uploading.As an object lesson, when another node sent similar or corresponding the inquiry, one or more intermediate nodes can provide the entity of being asked after a while, thereby described inquiry needn't be routed to the node with this entity.Some intermediate nodes are always online and/or have a big cache memory.But,, need the duplicate answer program so if the metadata in the cache memory of intermediate node is outmoded.
Attention has only when a certain node is received first request that relates to specific project in each embodiment, and this node is just uploaded entity to other node.In such embodiments, with regard to first request, entity can be uploaded, and perhaps is copied in the cache memory of other node and/or with the metadata of having uploaded to link.Notice that under the situation of not receiving any upload request, entity never is moved by access link in such an embodiment.
