Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1a is a flowchart of a decentralized instant messaging method according to an embodiment of the present disclosure. The method is suitable for the situation that all participants participate together through the communication server side. The method can be executed by a decentralized instant messaging device, which can be implemented in software and/or hardware and can be configured in a communication server of any party. As shown in fig. 1a, the decentralized instant messaging method of the present embodiment may include:
s101, according to the operation of local group members on a target group, determining a local group change event of the target group, and determining a local group state corresponding to the local group change event;
s102, acquiring other group change events of a target group and other group states corresponding to the other group change events from other communication service terminals;
s103, according to the local group state and the other group states, fusing the local group change event and the other group change events, and sending instant communication information to local group members in a target group according to a fusion result;
the local group members belong to local participants, and the other communication service terminals belong to other participants participating in the target group.
The embodiment of the disclosure provides a decentralized instant messaging system, which is used for realizing a decentralized instant messaging method. Referring to fig. 1b, the instant system includes at least two parties, each party having its own communication client (IM client), reverse proxy server, private gateway, communication server (IM server), database. The communication client of each participant is used by the user of the participant, the communication server of the participant can be accessed through the private gateway of the participant, and the communication server of other participants is not accessed, and the communication server can also store the communication data into the database of the participant. Data synchronization can be carried out between the communication service terminals of different participants. Specifically, the private gateway may be configured to perform identity authentication on the local user, and issue an authorization token for the local user if the identity authentication passes, so as to allow the local user to log in.
In the decentralized instant messaging system, a group can be participated in by at least two participants, so that the decentralized group can be realized. The participants in different groups may be the same or different. Referring to FIG. 1c, group A may be commonly participated by party X and party Y, group A including user 1 and user 2 in party X, and user 3 in party Y, available for communicating the first item; group B may be commonly engaged by party X and party Z, including user 4 in party X, and user 5 in party Z, available for communicating the second item. Therefore, the data of the group a is synchronized between the IM server X and the IM server Y, and the data of the group B is synchronized between the IM server X and the IM server Z.
The instant messaging system of the centralized group is also centralized, the composition of the group members is fixed, and the audience of the group messages is also fixed, namely, which group members comprise the group and which group members should receive the group messages are fixed, so the centralized instant messaging system can accurately push the group messages. However, the group in the decentralized instant messaging system is participated in by different participants, and has a distributed characteristic, and the group members and the group messages are dispersed at the communication server of each participant, i.e. the group members and the group messages have a characteristic of dynamic adjustment, such as that the group members can dynamically join and exit, and the group members in the target group and the target audience of the group messages are unknown when the group messages are sent out. Therefore, how to push group messages to the group members of the participants is important.
In the embodiment of the present disclosure, the target group is any group in the decentralized instant messaging system, the target group may be participated in by the local participant and other participants together, and the local participant may be any one participant. The local communication client is only connected with the local communication server but not connected with other communication servers, and the local communication server is in communication connection with other communication servers. The local group members are group members belonging to local participants, the local communication client is adopted to be connected with the local communication server, the other group members are group members belonging to other participants, and the other communication clients are adopted to be connected with the other communication servers.
The group state is used to represent the state of the target group in the corresponding group change event generation process, and may be a group member condition or a group message condition in the target group. Specifically, the local communication server may obtain an operation of a local group member on the target group from the local communication client, determine a local group change event of the target group according to the operation, and use a group state where the target group is located in a process of generating the local group change event as the local group state, for example, determine a previous event relative to the local group change event as the local group state; the local communication server can also obtain other group change events of the target group synchronized by other communication servers, and the other group state of the target group in the process of generating the other group change events, for example, the event before the change event of the other group is determined as the other group state; and generating other group change events according to the operation of other group members in other participants on the target group. The local communication server side also fuses the local group change event and other group change events according to the local group state and other group states to obtain a fusion result, and sends an instant communication message to the local group members in the target group according to the fusion result, namely, the local audience of the group message in the local participant can be determined according to the fusion result, and the group message is sent to the local audience. Each communication service end in the instant communication system determines a local group change event, also takes the group state of the target group as the local group state in the process of generating the local group change event, synchronizes other group change events and other group states determined by other communication service ends, fuses the local group change event and other group change events according to the local group state and other group states, obtains a local audience of group messages in the target group, sends the group messages to the local audience, and can improve the stability of instant communication. In addition, each communication server in the decentralized instant communication system only processes the group data participating in the communication server, but does not process irrelevant group data.
According to the technical scheme of the embodiment of the disclosure, the local group change event and the corresponding local group state are determined through the local communication server, other group change events and the corresponding other group states are synchronized from other communication servers, the local group change event and other group change events are fused according to the local group state and the other group states, a local audience of the group message in the target group is obtained, the instant communication message is sent to the local audience, and the stability of instant communication can be improved; in addition, each participant only processes the group message in the group to which the participant belongs, so that the leakage of the group data can be avoided, and the safety of the group data is improved.
In an alternative embodiment, the local group change event comprises a local group member change event and/or a local group message change event; the other group change events comprise other group member change events and/or other group message change events; the local group status is an adjacent group change event that precedes the local group change event; the other group status is an adjacent group change event that precedes the other group change event.
The local group member change event refers to a member change event such as member joining, member exiting, or member authority adjustment triggered by a local group member in the target group, and the local group message change event refers to a message change event such as message sending, message collection, message deletion and the like of the local group member in the target group after the target group. Accordingly, other group member change events, other group message change events are triggered by other group members in the target group.
The local group state corresponding to the local group change event may be a relative previous event depended on or hidden by the local group change event, and the other group state corresponding to the other group change event may be a relative previous event depended on or hidden by the other group change event. Optionally, a previous group change event of the local group change event in the target group is used as the corresponding local group state, and a previous group change event of the other group change events in the target group is used as the corresponding other group state. The content of the local group status, the content of the other group status, and the affiliated party are not particularly limited, and the content may be a group member change event or a group message change event. The local group state and the local group change event can belong to the same party or not belong to different parties; other group status and other group change events may or may not belong to the same party.
Each participant not only determines the group message change event, but also determines the group state corresponding to the group message change event, and synchronizes the self group message change event and the corresponding self group state to other participants, so that the group message change events of the participants are convenient to be fused, and the target audience of the group message in the target group is determined.
Fig. 2a is a flow chart of another decentralized instant messaging method according to an embodiment of the present disclosure. This embodiment is an alternative proposed on the basis of the above-described embodiments. In the scheme, the local group change event comprises a local group member change event and/or a local group message change event; the other group change events comprise other group member change events and/or other group message change events; the local group state is an adjacent group change event before the local group change event; the other group status is an adjacent group change event that precedes the other group change event. Referring to fig. 2a, the decentralized instant messaging method of the present embodiment may include:
s201, according to the operation of local group members on a target group, determining a local group change event of the target group, and determining a local group state corresponding to the local group change event;
s202, acquiring other group change events of the target group and other group states corresponding to the other group change events from other communication service terminals;
s203, according to the local group state and the other group states, fusing the local group change event and the other group change events to obtain a target group message change event corresponding to the local group member change event; the target group message change event is the local group message change event and/or other group message change events;
s204, according to the local group member change event, sending a group message corresponding to the target group message change event to the local group member in the target group;
the local group members belong to local participants, and the other communication servers belong to other participants participating in the target group.
Specifically, the local communication server obtains a previous event relative to the local group change event according to the corresponding local group state, that is, obtains an adjacent group change event on which the local group change event depends; and obtaining the events before the other group change events according to the corresponding other group states, namely obtaining the adjacent group change events which are depended by the other group change events.
Responding to the event of changing the local group members, the local group members in the target group are changed such as joining, exiting, role adjustment and the like, and the composition of the local group members is relatively fixed after the change. Under the condition that the target group comprises the user 1 and the user 2 of the local participant, responding to the change event of the local group members, and the user 3 of the local participant joins, the target group after the change comprises the user 1, the user 2 and the user 3 of the local participant. The target group message change event corresponding to the local group member change event refers to a target group message change event which takes the changed local group member as a target audience, and the target group message change event can be a local group message change event initiated by the local group member and/or other group message change events synchronized from other communication service terminals. Fusing the local group change event and other group change events according to the local group state and other group states to obtain a target group message change event corresponding to the local group change event; and determining the composition of the local group members according to the local group member change event to obtain a local audience of the target group message change event, and sending a group message corresponding to the target group message change event to the local audience. The target group message change event corresponding to the local group member change event is obtained by fusing the local group change event and other group change events, the composition of the local group member is obtained according to the local group member change event and is used as a local audience, and the corresponding target group message change event is sent to the local audience, so that the group message is forwarded, the unknown problems of member composition in the target group, the target audience of the message and the like are solved, and the accuracy of message forwarding in the decentralized instant communication system is improved.
In an optional implementation manner, the merging the local group change event and the other group change event according to the local group state and the other group state includes: constructing a vertex in the directed acyclic graph according to the local group change event and the other group change events; determining edges in the directed acyclic graph according to the local group state and the other group states; and fusing the vertexes and the edges in the directed acyclic graph.
Specifically, the local communication server may construct a Directed Acyclic Graph (DAG), and perform fusion classification based on the DAG to obtain a fusion result. Specifically, the local group change event and the other group change events may be used as vertices, directed edges pointing to the local group change event from the adjacent group change event of the local group change event are constructed according to the corresponding local group state, directed edges pointing to the other group change event from the adjacent group change event of the other group change event are constructed according to the corresponding other group state, and a directed acyclic graph is obtained. And fusing the directed acyclic graph to obtain a target group message change event corresponding to the local group member change event. Referring to FIG. 2b, IM server X constructs a directed acyclic graph according to the self-generated group message change event X-1, group member change event X-2, and group message change event X-3, the group message change event Y-1 and group member change event Y-2 synchronized from IM server Y, the group message change event Z-1 synchronized from IM server Z, and the corresponding group states. Referring to fig. 2c, the target group message change event corresponding to the group member change event X-2 includes a group message change event X-3, a group message change event Y-1, and a group message change event Z-1. The local communication server side can obtain the target group message change event corresponding to the local group member change event by constructing the directed acyclic graph and classifying and fusing the directed acyclic graph, so that the accuracy and the efficiency of fusion can be improved, and a foundation is laid for accurately and efficiently sending the message.
According to the technical scheme of the embodiment of the disclosure, the local group change event and the other group change events are fused according to the local group state and the other group states, so that the target group message change event corresponding to the local group change event is obtained, the local audience of the target group message change event is obtained, and the message forwarding accuracy in instant messaging can be improved. The fusion is carried out based on the directed acyclic graph, so that the accuracy and the efficiency of the fusion are further improved.
In an optional implementation manner, the sending, according to the local group member change event, a group message corresponding to the target group message change event to a local group member in the target group includes: if the dependency relationship exists between at least two target group message change events, sequencing the at least two target group message change events according to the dependency relationship; otherwise, sequencing the at least two target group message change events according to the time stamps of the at least two target group message change events; and according to the local group member change events, sending the group message corresponding to the target group message change event to the local group members in the target group according to the sequence between the target group message change events.
Specifically, if there is a dependency relationship between at least two target group message change events, for example, a node of a first target group message change event refers to a node of a second target group message change event, the first target group message change event depends on the second target group message change event, and the second target group message change event may be sorted in front. In connection with fig. 2b and 2c, the group message change event Z-1 is dependent on the group message change event Y-1, so that the group message change event Y-1 precedes the group message change event Z-1. If there is no dependency between at least two target group message change events, for example, the third target group message change event and the fourth target group message change event both refer to the first target group message change event, the third target group message change event and the fourth target group message change event may be sorted according to the timestamp of the third target group message change event and the timestamp of the fourth target group message change event, i.e., the timestamps are sorted before. With reference to fig. 2b and 2c, there is no dependency between the group message change event X-3 and the group message change event Y-1, and the ordering may be performed according to the timestamp. And the local communication server sends the group message corresponding to each target group message change event to the local group member corresponding to the target group member change event according to the sequence among the target group message change events. The target group message change events can comprise local group message change events and/or other group message change events, namely the group messages to be forwarded can come from local participants and/or other participants, and the forwarding sequence of the target group message change events is obtained by sequencing the target group message change events, so that the accuracy of forwarding the group messages in the target group can be further improved.
In an optional implementation manner, the sending, according to the local group member change event, a group message corresponding to the target group message change event to a local group member in the target group includes: determining effective local group members in the target group according to the local group member change event; and sending the group message corresponding to the target group message change event to the effective local group member.
Specifically, the local group members corresponding to the local group member change event may be composed as the local group members valid in the target group by the local participant, and the group message corresponding to the target group message change event may be sent to the valid local group members. The audience of the target group message change event in the local participant can be accurately positioned according to the local group member change event, so that the accuracy of group message forwarding is improved.
In an alternative embodiment, the method further comprises: according to the local group state and the other group states, fusing the local group change event and the other group change events to obtain other group member change events corresponding to the local group member change events; determining other effective group members in the target group according to the corresponding other group member change events; and generating a group member list of the target group according to the effective other group members.
In the fusion process, not only the target group message change event corresponding to the local group member change event can be obtained, but also the sequence between the local group member change event and the other group member change events can be determined, so as to obtain the corresponding relationship between the local group member change event and the other group member change events, and referring to fig. 2c, the group member change event X-2 is located before the group member change event Y-2. The local group member change event makes the local group member relatively fixed, and the corresponding other group member change event makes the other group member relatively fixed. Specifically, the other group members corresponding to the other group member change event may be composed as other group members valid in the target group by the other participants, and a group member list of the target group is generated according to the valid local group member corresponding to the local group member change event and the valid other group members corresponding to the other group member change event. The local communication server can display the group member list by controlling the local communication client, so that local group members can conveniently select message receivers from the group member list, and the operation convenience of a target group is further improved.
Fig. 3a is a flowchart of another decentralized instant messaging method according to an embodiment of the present disclosure. The present embodiment is an alternative proposed on the basis of the above-described embodiments.
