Description

Session information synchronization method and device, computing equipment and storage medium

Technical Field

The present invention relates to the field of data synchronization technologies, and in particular, to a method and an apparatus for synchronizing session information, a computing device, and a storage medium.

Background

Instant Messaging (IM) is a tool based on internet online real-time communication, and comprises functions of text message chat, file transmission, voice or video communication and the like. Instant chat software common in life, such as WeChat, QQ, nailing and the like, some online games, social applications and the like, can be described as instant communication tools. Instant messaging is of different types for personal applications and enterprise applications. After the instant messaging application is installed on a computer or a mobile terminal, a user can register an account number to perform instant message communication with one or more other users. The online instant chat tool of the webpage version can make up for a plurality of inconveniences brought by third-party chat software, and can realize the functions of automatic off-line message storage, push prompt after online, chat person online state display, cross-browser compatibility and the like.

The most core functions in the instant messaging system are message synchronization and storage, the message synchronization generally supports online and offline pushing and multi-terminal synchronization, the message storage refers to cloud storage, and all historical messages can be checked by logging in an account at any terminal.

However, instant messaging has some problems, for example, instant messaging software is various, and the problem of intercommunication between different IM software is not solved: different users may use different instant messaging software, and the various software cannot communicate directly, so that multiple IM software needs to be adopted simultaneously to communicate with multiple users.

In the existing instant message synchronization scheme, the problem of message loss is generally solved by combining the latest message cache and the historical message request. However, if the user has too many historical messages, the traffic consumption will be obviously increased, which is not favorable for the user to experience browsing the messages. Moreover, when synchronizing the session list, most of them adopt a direct and full synchronization method, which may cause message repetition.

Therefore, a method for synchronizing session information is needed, which can solve the problems of jamming and blocking in the data synchronization process when the data volume is large.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The message synchronization architecture of the current IM instant chat system is generally stored first and then synchronized. The message has two libraries for storing, one is a message storage library, which is used for storing all messages of all sessions, and is mainly used for supporting message roaming. The other is a message synchronization library which is mainly used for the multi-end synchronization of the receiving party. The server side stores the message in a message storage library and then stores the message in a message synchronization library. And for the receivers with failure on-line push or off-line push, the receivers actively pull all unsynchronized messages to the server. When the amount of messages is large, the problems of jamming and synchronization message faults are easy to occur. In order to solve the above problem, the present scheme provides a method for synchronizing session information, which can effectively solve the problem of loss of synchronization information, reduce traffic consumption, and improve user experience.

FIG. 1 shows a schematic diagram of the construction of a computing device 100 according to one embodiment of the invention. In a basic configuration 102, computing device 100 typically includes system memory 106 and one or more processors 104.

Theexample processor core 114 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. Theexample memory controller 118 may be used with the processor 104, or in some implementations thememory controller 118 may be an internal part of the processor 104.

Depending on the desired configuration, system memory 106 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 106 may include an operating system 120, one or more programs 122, and program data 124. In some embodiments, program 122 may be arranged to operate with program data 124 on an operating system.

Computing device 100 may also include an interface bus 140 that facilitates communication from various interface devices (e.g., output devices 142, peripheral interfaces 144, and communication devices 146) to the basic configuration 102 via the bus/interface controller 130. The example output device 142 includes a graphics processing unit 148 and an audio processing unit 150. They may be configured to facilitate communication with various external devices, such as a display or speakers, via one or more a/V ports 152.

An example communication device 146 may include a network controller 160, which may be arranged to facilitate communications with one or more other computing devices 162 over a network communication link via one ormore communication ports 164.

In some embodiments, the computing device 100 may be configured to perform amethod 200 for synchronization of session information in accordance with the present invention. Among other things, one or more programs 122 of computing device 100 include instructions for performingsynchronization method 200 of session information in accordance with the present invention.

The scheme comprises session synchronization and information synchronization. The session refers to a chat between a user and a chat object, such as a user, a group, a chat room, and the like. A session is a carrier of information, the type of which may be text, voice, picture, file, location, etc. When synchronizing session information, firstly, a session needing synchronization is determined, and then the information in the session is synchronized.

Fig. 2 shows a schematic flow diagram of amethod 200 for synchronization of session information according to an embodiment of the invention. The method may be performed in a computing device 100, where the computing device 100 has an application resident therein for instant messaging, and the computing device is networked with a server. As shown in fig. 2, the method is suitable for step S210, and first, in step S210, a login status of an application account is detected, and when the application account is switched from an offline status to an online status, a user full session version number is obtained from a server coupled to a computing device.

The login state of the application account can be a single-ended online state, a multi-ended online state or an offline state. According to an embodiment of the invention, an application account can log in at the same time from an instant messaging application webpage end and a mobile phone client or an iPad client. And when the application account is in a multi-terminal online state, updating the session information of the respective user at a plurality of login terminals at the same time. Specifically, the operation information of the application account on the session information at each login terminal can be acquired, the operation information is synchronized to other terminals, and the operation information is displayed on interfaces of other terminals. When the application account is in an online state, user session information from the server is received and stored locally. In order to reduce the consumption of traffic when session information is synchronized, when it is detected that the application account is switched from the offline state to the online state, the full session version number of the user may be obtained from a server coupled to the computing device. Each session corresponds to a version number, the version number is updated each time the content or state of the session changes, and the version number of the session is maintained in the server. Therefore, whether a certain session information is changed or not can be judged according to the version number. Each user saves a version number of all the sessions, and when the version number of any one session changes, the version number of all the sessions of the user is updated, so that whether all the sessions of the user change or not can be judged according to the version number of all the sessions of the user, and when the session information does not change, the session information does not need to be updated.

Subsequently, in step S220, it is determined whether the obtained all-session version number of the user is consistent with the locally stored all-session version number of the user, and if not, all-session summary information of the user is obtained from the server, where the session summary information at least includes IDs and version numbers of the sessions.

When the obtained all session version numbers of the users are different from the all session version numbers of the users stored locally when the session information is synchronized last time, the session information is changed. The user's entire session summary information may be obtained first. The session summary information records basic information of a session, including an ID, a version number, and the like of the session.

Next, in step S230, the ID of each session is used as an index, and the obtained version number of each session is compared with the version number of each session stored locally, so as to determine the changed session.

According to an embodiment of the present invention, the obtained version number of each session of the user may be compared with the locally stored version number of each session of the user in a one-to-one manner. When the ID of a certain session stored locally does not exist in the acquired session summary information, it is determined that the session is a deleted session. And when the version number corresponding to the ID of a certain session stored locally is inconsistent with the acquired version number corresponding to the ID of the session, determining that the session is a modified session. When the acquired ID of a certain session does not exist in the local storage, it is determined that the session is a newly added session.

The chat network protocol is generally divided into two forms of server active push and client active pull. In order to ensure efficient, low-consumption information synchronization, both may be used in combination. In one implementation of the present invention, a manner of asynchronously obtaining data may be employed. For example, a listening interface is registered in the user interface, and in the observer mode, data is acquired from the memory whenever a change in data is monitored.

Finally, in step S240, the information of the changed session is obtained from the server, and the cache is updated.

For the deleted session, the session details of the session can be paged and updated to the local cache for the new or modified session. The session details include all information included in a session, for example, an ID, a title, an identifier, and a latest piece of data of the session.

When the application account is in an online state, session information is synchronized by using a server in an active push mode, and when the application account is in an offline state, if too many messages are received by a client, in order to reduce traffic consumption, the latest session information can be selectively synchronized after the application account is online, but not all the messages. The session information includes ID, content, time, etc. of the information. According to one embodiment of the invention, at least one piece of latest data of the information of the changed session may be first acquired from the server. For example, the latest page of data obtained by paging may be used. Then, before the at least one latest data, a piece of fault information is inserted, wherein the fault information marks the ID of the first piece of information in the at least one latest data. When an instruction of searching for history information of a user is received, acquiring history information before an ID of a first piece of information in at least one piece of latest data from a server based on the fault information, finishing updating when the acquired history information is overlapped with locally stored history information, and deleting the fault information. If no fault message exists, the session information cached locally is directly used without updating, so that the consumption of flow and the use of memory can be greatly reduced.

For example, the ID of the information stored locally when the application account was online last time is 1-5. When the user account is switched from the offline state to the online state, the latest page of data, for example, ID 9-13, may be synchronized first, and then fault information, in which ID9 of the first piece of data of the updated information is marked, may be inserted before the first piece of data of the updated information, that is, the data of ID 9. When the user turns up to search the historical information, the information generated in the offline process is acquired from the server by combining the fault information, and the synchronization of the historical information is finished until the acquired historical information is overlapped with the locally stored information. I.e. data with an ID of 6-8 is acquired.

Fig. 3 is a schematic structural diagram of a session information synchronization apparatus 300 according to an embodiment of the present invention. As shown in fig. 3, the apparatus 300 includes a first obtaining module 310, a determining module 320, a second obtaining module 330, a comparing module 340, and an updating module 350. The first obtaining module 310 may obtain the full session version number of the user from a server coupled to the computing device when it is detected that the login state of the application account is switched from the offline state to the online state. The determining module 320 may determine whether the obtained all session version numbers of the users are consistent with all session version numbers of the users stored locally. When the two are consistent, the session information does not need to be updated. The second obtaining module 330 may obtain, when the obtained user full session version number is not consistent with the locally stored user full session version number, the user full session summary information from the server, where the session summary information at least includes an ID and a version number of each session. The comparing module 340 may use the ID of each session as an index, and compare the obtained version number of each session with the version number of each session stored locally to determine the changed session. The update module 350 may obtain information of the changed session from the server and update the cache. The functions and specific execution logic of the above modules may refer to the flow of themethod 200, and are not described herein again.

According to the scheme of the invention, a double-layer version number judgment mechanism is adopted, so that the consumption of flow can be reduced when the session information amount is large; by adopting the scheme of asynchronously acquiring data, the load of the server can be reduced, IO (input/output) operation is effectively reduced, the throughput of the server is greatly improved, and the problem of blockage of a client under the high concurrency condition is solved; by adding fault information in the session information synchronization process, data loss can be avoided, and the integrity of session information updating is ensured.
