Description

Management method and system for instant messaging service

technical field

The invention relates to the field of computer network and communication. More specifically, it relates to a management method and system for instant messaging services.

Background technique

With the rapid development of information network technology and people's increasing demand for communication, network services (such as: email, online video, e-commerce and instant messaging, etc.) continue to emerge. Among the many information network services, Instant Messaging (IM) service is developing rapidly. Its convenience, real-time performance and low cost are destined to surpass the traditional communication methods and become the mainstream communication means. Instant messaging can be said to be the most lethal application on the Internet after Electronic Mail (E-mail) and World Wide Web (WWW). Compared with traditional communication methods such as telephone and E-mail, instant messaging not only saves costs, but also is very efficient.

Due to the rise of instant messaging software, the "content" capable of instant intercommunication is rapidly expanding from voice to image, text, data, etc. The future value of instant messaging lies in communication on multiple platforms such as telephones. The content of instant communication is not only voice, but also images, data, data, etc.; the terminal device can be not only a computer, but also a mobile phone; the version of instant messaging software not only has a PC (Personal Computer) version, but also a mobile version and a web version Wait. In general, instant messaging software enables users to communicate with anyone anytime, anywhere.

Although the "multi-function" and "ultra-convenience" of the instant messaging service can greatly improve the user experience, it will inevitably bring a certain burden to the network. Looking at these network services, it can be seen that there are problems such as different implementation methods, different service types, and different service terminals among services, which makes it difficult to control and manage instant messaging services in a unified manner.

In order to solve the above problems, the service identification theory of pervasive services is proposed in the integrated identification network system and key technologies [1], and the corresponding analytical mapping model is established, and based on this, the unified processing mechanism and mechanism of the service layer are created to provide Universal service. In the new model of the integrated identification network, a virtual service module and a virtual connection module are introduced into the service layer. The virtual service module can solve unified service object scheduling, provide controllable and manageable services, and provide the possibility to support multiple services. The key is to introduce the concept of service identifier (Service IDentifier, SID) to uniformly classify and describe various network-supported services, and then design a unified service processing mechanism (including service registration, service query, service establishment, etc.) on this basis.

In the context of the integrated identification network, a specific service identification generation mechanism for web resources and services has been proposed, that is, a Uniform Resource Locator (Uniform Resource Locator, URL) is used to generate the SID of the web resource. However, the design and research on how to realize the unified classification, description and processing of instant messaging services have not been in-depth. Current network resources adopt a host-centric naming method. Web pages and other resources on the Internet use URLs. The first half of each URL indicates the domain name of the host, and the second half indicates the location of the resource on the current host. Web resources and services can use URLs because their location on the network is fixed. Every file on the Internet has a unique URL, which contains information indicating where the file is and how the browser should view it. deal with it.

However, for instant messaging services, if the URL is still used, this method is no longer applicable. The main reasons are as follows: (1) Only the account number of instant messaging users is fixed, but the status will change each time they register for the service. different. (2) Instant messaging provides an end-to-end instant conversation service, which changes with changes in user status. For example, the user's login status changes from online to offline, the software version number of the user's login changes, and the terminal type of the user's login changes, etc., all of which will lead to changes in the instant messaging service. Combining the above two reasons, it is necessary to determine the service identification according to the characteristics of instant messaging itself, and use the service identification to complete the unified and efficient management of instant messaging services.

Patent document [2] proposes a unified description method for network resources and services, mainly for the search of Internet services and resources, and proposes a unified description method based on ontology description, linking resources and services through attributes, so as to realize the Unified lookup of resources and services. The present invention includes: the Internet including local area network, wide area network and mobile communication network, and its key steps are: defining the class hierarchy of the ontology; defining attributes; users registering the resources and services they provide with the registration center; and the user end inquiring about network resources. The present invention unifies the network resources and services that customers need to obtain from the network in form, and based on this unification, the registration and query of resources and services can be realized.

The disadvantages of this scheme are:

(1) This scheme does not take into account the uncertain characteristics of instant messaging service login status. The unified service description method proposed in this scheme mainly relies on the location uniqueness and invariance of services and resources, and describes resources located in a certain network location with a unique service identifier, and manages them through the service identifier. However, only the account number of the instant messaging user is fixed, and the status may change each time the service is registered. For example, the version number of the client terminal to log in, the terminal type to log in, etc. will be different. When any element in the user status (including login status, login client version number, etc.) changes, the instant messaging service registered by the user will be different.

(2) This scheme does not consider the immediacy characteristics of instant messaging services. Instant messaging provides an end-to-end instant session service. When any element in the user status (including login status, login client version number, etc.) changes, this service will change with the change of the user status. However, the service description method proposed in this scheme is only for static services.

Patent document [3] provides a network naming mechanism and a name resolution mapping system, belonging to the field of network technology. In the naming mechanism of the present invention, the data or service publisher or requester first sends a data or service request; then the relay layer is responsible for extracting the metadata of the data or service; and then a string is obtained through a hash algorithm, which is used for Identify the extracted data or services. The name resolution system of the present invention uses a three-layer network structure—maintenance layer, implementation layer and relay layer to realize, utilizes the resolution mapping of the names named by the above rules, thereby replacing the existing DNS name resolution mapping system, effectively Implemented network name resolution mappings. The invention realizes the unified description of the data and the service through the unified naming of the data and the service, and uses a three-layer network structure to realize the name resolution processing, thereby effectively realizing the name resolution mapping and reducing the waste of network resources.

The disadvantages of this solution are: the solution does not specify the specific components of the name when naming the network service, and mentions the use of web crawlers to actively discover resources in the network, and then analyze the web page information, and extract the location information for network data. For the service, the service provider information is extracted, and then the relay layer is responsible for extracting the meta information of the data or service. However, there is no further elaboration on the specific content of the service provider information.

Patent document [4] relates to the technical field of instant messaging, in particular to a method and system for implementing instant messaging services. The present invention is an instant messaging service implementation method and system thereof, which pre-assigns area codes and language version information to users in each area, uses the area codes and the instant messaging numbers of each user to perform identity verification on instant messaging users, so that users Be able to log in to the instant messaging service system, and record the user's language version information after the user logs in successfully. During the user interaction process, use the recorded language version information to perform code conversion and text translation for the displayed content, so as to realize different regions. Interconnection between users. Utilizing the present invention, each user can communicate with other users using their familiar language interface and language, so that the communication between users is no longer restricted by region and language, thereby greatly improving the service quality of instant messaging services .

The disadvantage of this scheme is that although this scheme proposes a unified management method for instant messaging services, using this method, the client type, client version number, and terminal type cannot be distinguished among various instant messaging services. This program focuses more on solving the problem of language habits between different regions. Due to different language habits, there are different ways of saying the same thing in different regions. For example, the mainland is called pineapple, while it is called pineapple in Taiwan. The inconsistency of such statements will create certain difficulties for user communication when users in different regions are interconnected. Although using this solution can solve the problem of language habits, the more important problem - unified management of service identification has not been solved.

Step l: If no, go to step j.

As shown in Figure 2, at least six sets of collected information are generated through a hash function one by one to generate a hash value, and the generated hash value is combined as the service identifier of the instant messaging service, and stored in a centralized or distributed storage mode.

Specifically, each group of the collected user account, user password, instant messaging service name, client version, client terminal type, and login status information generates a set of strings through a hash function, and the process of service identification can be passed Expressed as follows:

Z _SID ＝＜Φ(U ₁ ),Φ(U ₂ ),Φ(C ₁ ),Φ(C ₂ ),Φ(T ₁ ),Φ(T ₂ )＞

Among them, Z _SID represents the instant messaging service identifier, Φ represents the hash function, and the service identifier can be obtained by mapping the six-element information group through the hash algorithm. U ₁ , U ₂ , C ₁ , C ₂ , T ₁ , and T ₂ represent user account, user password, instant messaging client name, client version, client terminal type, and login status, respectively.

The set of the character strings is the service identification of the instant messaging service, and the security of the service identification is ensured by utilizing the irreversible mapping property of the hash function from plaintext to ciphertext.

As shown in FIG. 3, the service identifier is stored in a centralized or distributed storage mode.

As shown in Figure 4, a management system for instant messaging services includes an information collection unit, a service identification generation unit, a service identification storage unit, a login authentication unit, a service management unit and a judgment unit;

It needs to be further explained that the heartbeat information is the heartbeat packet sent by the client at regular intervals after logging in to the instant messaging service. The heartbeat packet is used to prove to the server that the client is still online. If the client heartbeat information is received, the client is considered to be offline.

<Example of registration and login process>

WeChat users register as users on the mobile phone through the WeChat 6.3.15 client, fill in the account password and other information and click Register, and the information collection unit collects at least the user account number, user password, instant messaging service name (WeChat), and Client version (6.3.15), client terminal type (mobile phone) and login status; the service identification generation unit generates a hash value from the collected information through a hash function, reassembles it as a service identification, and converts the service identification The service identifier is transmitted to the service identifier storage unit, and the service identifier storage unit stores the service identifier, wherein the login state is an empty state.

After the registration is completed, the user logs in through the WeChat 6.3.15 client on the mobile phone, and the information collection unit collects at least the user account, user password, instant messaging service name (WeChat), and client version (6.3.15) based on the received login information. , client terminal type (mobile phone) and login status, the service identification generation unit generates the hash value through the hash function through the collected information, and reassembles it as a new service identification, and the login authentication unit judges the user account number and user ID in the new service identification Whether the hash value generated by the password is consistent with the hash value generated by the user account and user password stored during registration, if they are consistent, the login is allowed, and if they are inconsistent, the login is rejected.

After the login is successful, check whether the hash value of the instant messaging service name, client version, and client terminal type in the new service ID is consistent with the hash value of the communication service name, client version, and client terminal type in the stored service ID; If they are consistent, the online status hash value in the latest service ID is replaced with the offline status hash value in the stored service ID; if not, the new service ID is stored.

The service management unit manages the WeChat user according to the stored service identification, and completes the instant messaging function of WeChat.

<Example of Instant Messaging Service Management System>

User A logs in at the QQ client on the PC side, and the information collection unit in the service identification management system collects at least the QQ user account number, QQ user password, instant messaging service name (QQ), client version, and client terminal type according to the received login information (PC) and login status, the service identification generation unit generates a hash value through the hash function through the collected information, and reassembles it as a new service identification, and the login authentication unit judges the hash generated by the user account number and user password in the service identification Whether the value is consistent with the hash value generated by the user account and user password stored during registration or last login. If they are consistent, this login is allowed, and if they are inconsistent, this login is rejected.

After the login is successful, the update module in the login authentication unit compares the hash value of the instant messaging service name, client version and client terminal type in the new service identification with the communication service name, client version and client terminal type in the stored service identification The hash values are matched; if the match is consistent, the online status hash value in the latest service ID is replaced with the offline status hash value in the stored service ID; if they are inconsistent, the new service ID is stored.

User A who is in the online state sends the account information of the communication object B to the service management system, and the query module of the service management unit performs service identification query in the storage unit according to the user B account number, and returns all the searched online service identifications of B users For user A, if there is only an offline service ID in the storage unit, then return the offline information of user B; if there is no information about user B, then return the search failure information to user A, after successfully finding the service ID of user B, the query module further returns Establish communication between A and B to ensure the instant messaging function.

The distinguishing module of the service management unit determines the communication protocol of the instant messaging service QQ according to the instant messaging service name, i.e. QQ, and adjusts the system to make it compatible with the instant messaging service QQ; the version unification module ensures that users A and B have different client versions , can still communicate normally; the terminal unified module ensures that users A and B can still communicate normally when the types of client terminals are different.

The distinguishing module of the service management unit supports a variety of communication protocols, such as UDP, HTTP, etc., and distinguishes the communication protocols according to the hash value of the instant messaging service name in the service identification. An instant messaging software uses a fixed communication protocol to complete the communication , For example, QQ uses the UDP protocol. The communication protocol used by the instant messaging service can be determined only through the instant messaging name. And complete the communication between users A and B according to the communication protocol identified by the distinguishing module.

The version unification module supports multiple client versions, and compares them according to the hash value of the client version stored in the service identification and the hash value of the client version stored by the communication partner. If the two are the same, communicate directly; if they are different, the version unification module will select the one with the lower version to complete the information transmission.

The terminal unification module, according to the hash value of the client terminal type in the service identification of the stored communication parties, the terminal unification module can support multiple terminal types, and compares in the terminal unification module according to the terminal type hash values of both communication parties , can communicate directly; if they are different, the terminal unified module transmits information according to the terminal types supported by both communication parties.

For example, the distinguishing module, version unifying module, and terminal unifying module respectively collect corresponding information. User A’s instant messaging service name is QQ, client version number is V6.2.1, terminal type is PC, and user B’s instant messaging service name is It is QQ, the client version number is V6.2.2, and the terminal type is mobile phone.

After the distinguishing module determines that the name of the instant messaging service is QQ, it determines that the communication protocol between the two parties is the UDP protocol, and uses the UDP protocol to complete the communication between the two parties. After the identification by the version unification module, it is determined that the versions of the two parties are inconsistent, and the version unification module will select the party with a lower version to complete the information transmission. In this example, the version number V6.2.2 of user B will be selected to complete the communication between the two parties. When the terminal unified module recognizes that the terminal types of the two parties are different, it will transmit information according to the terminal types supported by both parties.

After the user logs in, the judging module in the service management unit judges the user login status according to the heartbeat information sent by the user client; It is replaced by the hash value of the online state. It should be noted that the online and offline hash values are directly stored in the judging module without regenerating.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those of ordinary skill in the art can also make It is impossible to exhaustively list all the implementation modes here, and any obvious changes or changes derived from the technical solutions of the present invention are still within the scope of protection of the present invention.
