Abstract:
A System with mechanisms that allows for creating, storing and resuming a session without being bound by time is proposed here. In a system that allows for communication between parties when one side of the party has an account with the system whereas others who are trying to reach this party do not, creating a session and allowing for the same users to come back to resume the session is proposed. Resuming the Session by any of the associated users to the session is supported. This session can be operated through various applications such as voice, video and chat and be accessed in various networks such as the interne and telephone network as well as across devices such as web browser, smart device apps and mobile phones with SMS capability. The system proposed supports porting and reusability of the session across networks, applications and devices.

Description:
[0001]    HTTP URL that also contains the session identity along with identifying the proposes system. 
         [0002]    A system that supports interaction between users who are not in the same community or in other words who do not necessarily have an account with this system is proposed elsewhere (Utility Application No. 14607034, Peter et al.). In such a system when the interactions are completed between the users that can be considered the end of that engagement. Here we propose a system that stores the engagement as part of a session that does not terminate even though the users complete their interaction. In such a proposed system the users of the session are informed about this session in the form of a session identity link and can resume the same session although as another engagement using application modes such as voice, video, chat or a combination thereof. 
         [0003]    A user can start a chat message with another user and the network can create a perpetual session that encompasses this chat session. This perpetual session is then persisted in the core network of this system. The users will be informed via email as well as in the chat context itself about the perpetual session link. Now sometime in the future the user can click on that session link and arrive to this proposed system after which the user can engage with the other party via voice call. In another embodiment a user from a web browser is engaging with another user in the telephone network via the proposed system. Assuming that the user in the telephone network has an account with the system, the moment this engagement starts and this being the first one, the session link is indicated to both the users to their email addresses. For the user on the browser, the session link can be indicated to the chat window so as to allow the user to copy that link and keep it elsewhere securely. If there is an interruption in the telephone service due to poor network conditions and the user on the web browser also terminates the session because of unavailability of the user on the other side, the user on the telephone network who had received the session link via email can click and join the persistent session in the proposed system which in turn can seek out the other user who is currently present to the system. Even if not, the system can indicate to the user via email about the session being sought after by another user trying to connect both the users with the session. 
         [0004]    What was a call via PSTN Network now becomes a call via IP Network to a Web Browser across engagements. The context of the session is retained so that the users in this session can be made aware of all the past engagements and activities during those engagements. The entire engagement history for this perpetual session will be presented in a comprehensive manner to the users of the session. Although the session was originally created by a user (say a buyer was trying to reach a seller in the market) the session itself continues without any active user and based on certain features provided by the system can even continue to indicate to the users about ongoing information relevant to that session and allow for the users to join the session and continue the engagement with each other. 
       BACKGROUND OF THE INVENTION 
       [0005]    1. Field 
         [0006]    In an online marketplace where users are looking for items or service, there is a need to communicate with providers through email, chat, voice and video. While the providers have an account with a system that supports such modes of interaction, the visiting users such as buyers need not have an account with the system, one that has been proposed (Utility Application No. 14607034, Peter et al.) elsewhere. In such a system the visiting users may again want to re-engage with the providers or vice-versa. The proposed system here shall have the ability to persist sessions without any time limit and make it accessible through multiple networks like the internet and the PSTN for the users to re-engage with each other or even for a user to monitor or inquire things related to the session. This especially is very relevant in market places where the users are buyers and the provider is a merchant/seller although the invention is not limited to this environment. 
       USE OF TERMS 
       [0007]    The terms—buyers, users and consumers are used interchangeably and refer to the same or similar entity. The terms—sellers, providers, producers are also used interchangeably and refer to the same or similar entity. Depending on the type of the online marketplace or social network or e-commerce website, these terms are changed as relevant in those contexts. As an example, an online dating site uses the term users to refer to its user base who are trying to connect with others. An online auction site like ebay would use the terms buyers and sellers. An online marketplace connecting growers and bakers may use the term producers and consumers to its user community. This invention is applicable to similar users and not limited by the specific terms used to describe the users of the proposed system. 
       2. Description of the Related Art 
       [0008]    Many market places on the internet provide an environment where sellers of a service or a product can advertise their offering and prospective buyers can read thru the description of these products (examples like amazon.com, ebay.com, craigslist.org) and contact the sellers for further inquiries. However in these environment the most common mode of interaction is email. In some cases the seller publishes their phone number with the caveat that only serious buyers should contact them. Either we have a non real-time interaction such as email where the actual email of the seller can be hidden today or we have a case where the seller has to publish the phone number contact and be concerned on spam calls to it. Moreover the user (prospective client) if interested in immediate interaction with the buyer using the published phone number has to use their phone device whether landline or mobile to interact with the seller. The internet is progressing in that the web browser environment is being enhanced for real-time interactions via voice, video and data under the influence of html5. In this context it becomes much easier to provide these media (voice, video and data) via the browser without any special plug-ins, such as no flash will be required. 
         [0009]    Most of the market places are focused on the products or services themselves, providers and consumers have accounts and any sort of communication is either via email, phone numbers and in some cases can offer chat programs with the providers. However in these circumstances none of the solutions offer a persistent session between the users where even after the initial engagement the session continues for the users (say buyers and sellers) and they can re-engage and do so on a different mode of engagement as well, for example the buyer can engage on the session and make an outbound voice call to the seller and still keep the entire history of earlier exchanges. It is possible for a marketplace (U.S. Pat. No. 8,170,919 B2 May 2012 Barbour et al) to be created focused on the collaboration itself to be an essential ingredient and have tight integration of all activity that takes place between the users with the platform that hosts the products or services. However what is targetted here in the proposed system is to focus on the people involved, the communication aspects between them, to make their sessions persistent independent of the marketplace itself although such a solution can also be tightly integrated with marketplaces. 
         [0010]    What this invention proposed here, in one embodiment, is to persist the session context perpetually so that sessions can transfer from one medium to another spanning across networks (either internet or telephone network) and services (voice, video and text). Perpetual session id can also be re-used at a later time to connect with the same user without losing the context of prior interaction. This allows the users to get to the point where the conversation last ended and to pick it up from that point, especially if interaction gets discontinued due to network connectivity issues or if conversation requires multiple interactions at different times for a logical conclusion of the topic. 
       SUMMARY 
       [0011]    The various embodiments presented here as part of the proposal highlights the need and effectiveness of a perpetual session in context of interactions in online marketplaces where users are not constrained to a specific community. 
         [0012]    In one embodiment a buyer tries to reach the seller through a HTTP URL and reaches the proposed system that immediately generates a new perpetual session identifier and informs the buyer about this link so as to revisit the same session in the future. This happens regardless of whether the buyer was able to connect with the seller of a product or service. In another embodiment the buyer is requested to fill in certain information including the email identifier after which the perpetual session identifier which is indicated to the buyer instantly on the engagement screen is also notified to the buyer&#39;s email. 
         [0013]    Regardless of whether the seller is reached in real-time for this session, the seller will be notified of this new session that was initiated by this buyer. In one embodiment the buyer is unable to reach the seller in real-time and does not even leave a message but rather provides information such as email address. The seller who is being informed of this session, uses the session link to reach this proposed system that launches the seller with the engagement screen and allows the seller to initiate messages to the buyer. Here since the buyer did not leave any real-time information such as phone number, the system would be sending the seller&#39;s message via email. 
         [0014]    In one embodiment the buyer who has reached the seller via the browser may continue with either chat or voice or a combination but the buyer may have to leave the device or the terminal and be forced to take the session over a phone call. Here the buyer can request the seller to initiate a voice call to his or her phone after a while. In this case the buyer either remains on the session or leaves the session and resumes later using the session identifier. After resuming with the session, upon which the buyer is notified, the seller can initiate a phone call to the buyer on the other side. 
         [0015]    Perpetual user engagement is evaluated to see if it is associated with already existing session which can be found out based on how the users landed on the system. If they used a HTTP URL or hyperlink that did not contain a session identifier then this is a new session else it is a session that is resumed. The proposed system is capable of storing all the unique sessions in the system and able to retrieve them as and when needed. The persisted session must be associated with multiple URL such as one for each user so as to distinguish who the user is when they arrive at the system to access the session. 
         [0016]    In one embodiment the users in the system are given the option to completely remove the sessions but this will depend on the specific permissions for each of the users in the session. A system that implements the proposed mechanisms here can choose to have various features associated with terminating sessions. 
         [0017]    While most of the embodiments presented here are marketplaces scenarios the proposed system can be used in other situations including party events, fundraisers, and in social media advertising and also in normal conversations where users have a smart device App that aggregates all their sessions and the context with which the users can resume any of those sessions. The proposed system with its mechanisms also are independent of the market places themselves and do not have to be tightly integrated with any marketplace systems although that is a possibility.

       [0053]    The figures here depict preferred embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein. 
       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0054]    While there are applications that connect users in a community with the history of a chat session appearing in multiple devices running the same application, it is indeed limited to a user community and chat applications. In this invention where there is no necessity of a community between the parties in the session such as buyers and sellers not having to be in a common community, focus is on an endless session that encompasses all modes of communication and the ability to store and retrieve chat, voice, video or any other information exchange that happened in the context of a previous session. By generating a unique HTTP URL for the session as well as for the specific mode of interaction such as voice, video, chat and other assets involved in the engagement and being able to associate this with the persistent session and resources over a period of time, a rich interaction is made possible in a given setting. In this embodiment, we will discuss storing such a rich media interaction with a session identifier that can be used at a later time to retrieve the information from the server store. 
         [0055]    As illustrated in  FIG. 1 , the session identifier is used to store the entire session history in the central repository  101  that can be retrieved any time in the future or restored from a previous information exchange in cases of network failures resulting in communication disconnects. In one embodiment, session can start with  102  which is a chat or voice or video call whenever the user being reached is online on the server platform. If the user is offline or if there are network issues that disrupts ongoing communication between the two users, then session can automatically switch to  103  which is a PSTN based SMS or voice call. In another embodiment, session can start with  103  and later transition to  102 . The server uses perpetual session identifier to re-connect the two users. At the same time, user&#39;s PSTN identity is masked by the server session identity. 
         [0056]    This way, server can keep the same session identifier and use it across  104  and  105 , which gives it flexibility to be ported or transformed to multiple applications, networks and devices without losing context of an ongoing communication. Server maintains the session beyond the initial call as well as for re-use and retrieving history of the session at a later time as shown in  106 . This greatly helps in jumping back into the previous context of such an on-going and perpetual session and provides an easy continuity to conversations. Such sessions can also be sent over electronic mail formats (email) as shown in  107  with either a link to join the session or a detailed report of the entire conversation. While we talk about a perpetual session identity that gets created  102  for an initial session and gets stored  101  so as to be retrieved later when the session resumes, in reality in order for the system to recognize the user (say whether buyer or seller in a marketplace), there will be different session identity that gets generated and be notified to the user. A buyer will have a different perpetual session identity when compared to the identity that the seller would be notified. Both these identity will be referring to the same perpetual session however. This mechanism is necessary rather than having some URL parameters for the sake of security. It should not be possible for one user to pretend as another by changing the parameters in the URL and hence we need to generate different identity for each party in the session although all pointing to the same perpetual session. This mechanism is now assumed and will not be mentioned repeatedly in this document when we speak about perpetual session identity. 
         [0057]      FIG. 2  illustrates an embodiment where a session is started either in the form of  102  or  103  and server ( 101 ) generates a unique session identifier as part of the initial session establishment. The session identifier is then presented to the users in their conversation window using a hyperlink which is shown in  201 . Such a hyperlink points to a persistent session in the server as shown in  202 . Either of the parties involved in the conversation can click this persistent session link (which can be different for each each user) in the event of a communication loss resulting from network issues or going out of the service platform where communication exchange was taking place. Upon clicking the session link shown in  202 , users will be able to jump back into the previously interrupted conversation. 
         [0058]      FIG. 3  illustrates an embodiment of a retrieved session from a previous conversation. Since server maintains the session identity perpetually, it enables such a retrieval from either of the parties involved in the communication by clicking on the hyperlink given in  201  or shown again in  301 . Going through the history of that conversation, one can very quickly get to the point where the conversation can logically continue from its previous stage without having to spend much of the time. In one embodiment, user can retrieve a previously stored audio conversation by clicking  302 . Yet in another embodiment the retrieved information on the audio conversation can only indicate properties such duration of the audio conversation, codec employed, quality assessed, etc., but not the actual content of the audio which may not have been stored. On the same lines, a user can also retrieve a previously shared video and/or its properties by clicking on  303 . 
         [0059]      FIG. 4A  illustrates how the proposed system with its various components is used to provide perpetual attribute to the session in an user engagement system  400  that already exists. An existing user engagement system  400  offers session  405  oriented communication between its users  401 ,  402 . However this session will start and end with the interaction between the users  401 ,  402 . With the proposed system  410  the same session can be persisted beyond the initial interaction and can be retrieved at some time in the future to resume for further engagements. While the system  400  is per engagement, the proposed system  410  allows for various engagements on the same session that was initiated once. If the users  401 ,  402  so choose to re-engage as a new session they could in one embodiment. They simply have to connect via the user engagement system  400  without using a perpetual session link offered by the proposed system  410 . In one embodiment the user  401  connects with the user engagement system  400 . This user engagement system will interact  415  with the proposed system which will generate a new perpetual session identifier. The user engagement system  400  should inform  415  the proposed perpetual session management system on the link that the user  401  used to arrive at the user engagement system  400 . The system  410  understands that there was no perpetual session link in this engagement and hence generates a new perpetual session identifier  201  and gives it back to the  400  via the  415 . As part of this interaction  415  the system  400  will notify the content which is the perpetual session identifier to the user  401 . Now the user engagement system  400  will reach the user  402  and also inform that user  402  about the perpetual session identifier  301 . In another embodiment where based on the user  401  and the means they arrived to the user engagement system  400  it can be chosen not to support perpetual sessions in which case there will not be interactions  415  and hence no generation of perpetual session identifiers and hence no session information  201 ,  301  to the users. This shows that the user engagement system  400  can exist without the proposed system  410  and not offer perpetual sessions. As part of the session the system  400  can provide all the engagement details such as chat content, audio content and/or details including duration, codec used, quality that was assessed, video engagement, etc., via  425  interaction with the system  410 . The perpetual session information  413  and the resource information  421  shall be persisted in the active store  411  for a certain duration beyond the user engagements. If these stored data are not used for a while they shall be moved into the other storage  412  for later usage. In one embodiment the user  402  uses the perpetual session link  301  at a later point in time, the user engagement system  400  checks  415  with the proposed system  410 . There is no session in the cache  413 , the session retriever  414  does not find ( 417 ) the session in the active store  411  but finds it in the rare store  412  via  418 . The retrieved session is given back via  416  and  415  interactions. Then the user  402  is able to see the entire session and the history and is able to reach the  401  user using the user engagement system  400 . Although the user engagement system  400  itself is not proposed here but there will be some enhancements expected in such a system to use the session information retrieved  415  as well as the resource retrieved  425 . In one embodiment while the perpetual session link  201  generated for each users can have a common URL with different parameters to identify the users when they come back, it another embodiment a particular implementation can generate unique short form URL without any parameters and that short URL can again internally map to a longer set of parameters that identify the users along with other set of information. The longer form of URL with parameters exposed to users and network will be prone to manipulation whereas shorter form URL is not to that degree. Assume a user on a PSTN network lost the connectivity and need to rejoin the session, they can dial back the number (belonging to the user engagement system) from which they were reached. Upon dialing back they will be brought to the user engagement system  400  which will be responsible for mapping that phone call (based on the remote and local phone number) to the session for which the session URL will be retrieved by the user engagement system if stored in memory. If not the user engagement system  400  can inquire the proposed system  410  here which can detect the session URL based on the properties of phone number and any other session properties available. This highlights that while the proposed system has independent characteristics there will be some aspect to be supported in a user engagement system  400  that tries to leverage the proposed system  410 . 
         [0060]      FIG. 4B  illustrates a flowchart for one embodiment of the invention above. It describes the flow for Perpetual Session creation. A session request is initiated by the user as shown in  102 . This request is intercepted by the server,  1101 . If this is a session already persisted on the server, it is taken as a re-establishment request  1102 . If this is a new session request, server tries to connect the user to the requested provider/seller as in  1103 . If user is online on one of the registered devices, server creates a Perpetual Session Identifier as shown in  1105  for this new request. Server then publishes this session id to both users who are connected in the session. A session notification email is also sent out so that users can store them and reuse them. Server stores all associated properties of the session using this single Session ID that is perpetual. If a session already exists and conversation was interrupted due to a network connectivity issue or if user is trying to add another person to the conversation, server uses the perpetual session identifier to retrieve all the existing conversation history for the session and present the same to users. It also connects all users to the service using the same perpetual session id as shown in  1104 . 
         [0061]      FIG. 5  is a flowchart detailing the use of Perpetual Session to re-establish a lost connection and to transition the conversation from one device/network to the other where user has transitioned into. Let us take the example of an established web based chat session. When users are in a conversation, one of the users gets disconnected from the web session as shown in  1201 . Server detects the connectivity loss. However, server has a registration for the user with a PSTN phone number. With the use of Perpetual Session, server then tries to connect with the user who transitioned out of the web session via the PSTN phone number, which is SMS based as shown in reference numeral  1202 . In another embodiment, the same can be taken as an on-going voice conversation. When user transitions out of web session shown in  1201 , server will then try to re-establish the voice connection with PSTN phone as shown in  1202 . For the other user who stays connected, this transition is completely transparent. If server succeeds to connect the transitioned user as in  1203 , conversation continues. If the reachability check in  1203  fails, server can provide a message to the connected user about such a connectivity loss which is now considered an offline message. However, the invention enables server to maintain the conversation history in the Perpetual session which can be retrieved any time in the future. 
         [0062]      FIG. 6  extends the above flowchart of  FIG. 5 , to describe the flow of a session retrieval using the Perpetual Session ID. When user decides to retrieve an older conversation, the user starts by retrieving the session ID previously published by the server. If the web or phone session is no longer available by virtue of closing or deleting the conversation, the example uses an email where Perpetual Session link is stored ( 1301 ). When user clicks on the session link, the request is sent to the server. Server first checks to see if the conversation is still on-going. If so, it is considered as a re-establishment of a lost connection and the flow shown in  FIG. 5  is followed to re-connect the two users. If conversation has ended, server sends the entire session history to the user along with links to retrieve any voice and video interactions that happened in the previous conversation(s) using the same perpetual session identifier as shown in reference numeral  1302 . Upon receiving this history, user should have an ability to request a re-engagement or continuation of the conversation with the help of perpetual session id. When requested, server tries to see if the provider (other user) being contacted is online, as shown in numeral  1303 . If provider is online, then server will connect the two users as described in  1304  and also send this history to the provider. Conversation can then continue between the users with the same Session ID. This way, users will never lose the context of previous conversations and interrupted conversations can resume very easily from the last logical end point. If provider is unreachable, server will display an offline message to the user trying, but the user will still be able to see the previous conversations, as long as the perpetual session id is maintained. 
         [0063]    There may be a need for manual or administrative way of destroying such perpetual session ids by the administrator managing the server. This can be driven by automated policies of a fixed duration of time to preserve history or even based on some mutual agreements between the buyers and sellers on online marketplaces offering this service. 
         [0064]    In another embodiment based on certain deployments and customer needs it may be possible for the users to completely erase the session history. In another embodiment a user may be allowed to delete only their own part in the session whereas the other user(s) can still be able to retrieve the information that belongs to them. 
         [0065]    While perpetual session enables users to endlessly keep track of their conversation history, it extends on the idea of using a single HTTP identity for multiple modes of communication in any user space, be it a marketplace or a social network. The same perpetual session identifier can also be shared among other users to bridge into an ongoing conversation (conferencing). 
         [0066]    In another embodiment a perpetual session can be associated with certain feature set, wherein the features are active even without the users in the session. One such feature can be that which monitors if the users are reachable and connect them. Here we see that the (re) engagement between users was not because of a user initiating via a shared session link but by the session residing in the network. The feature set itself can be associated with the session through user&#39;s input or based on dynamic aspects of the session such as user&#39;s not be able to reach the other live and hence the proposed system has the ability to associate relevant features to the persistent session. 
         [0067]    Within this written description, the particular naming of the components, capitalization of terms, the attributes, data structures, or any other programming or structural aspect is not mandatory or significant, and the mechanisms that implement the invention or its features may have different names, formats, or protocols. Further, the system may be implemented via a combination of hardware and software, as described, or entirely in hardware elements. Also, the particular division of functionality between the various system components described herein is merely exemplary, and not mandatory; functions performed by a single system component may instead be performed by multiple components, and functions performed by multiple components may instead be performed by a single component. For example, the particular functions of the perpetual session and resource manager  413 ,  414 ,  421 ,  422 , and so forth may be provided in many or one module. Some of the functions of the proposed system  410  may have to be applied on the session manager  405  of an existing system. 
         [0068]    Some portions of the above description present the feature of the present invention in terms of algorithms and symbolic representations of operations on information. These algorithmic descriptions and representations are the means used by those skilled in the art to most effectively convey the substance of their work to others skilled in the art.
