Instant communication system and updating method for its linkman data

Abstract

The invention discloses an updating method for instant communication contact person information and an instant communication system. The method comprises steps of: setting contact person queue to be updated at client, adding contact person list into the contact person queue to be updated; triggering each contact person information updating process orderly and periodically according to the contactperson sequence in the contact person queue to be updated, obtaining latest contact person information from the server and storing the information in client. The system comprises client and a server.The client comprises: an adding module for adding a contact list into a contact person queue to be updated, and a contact person information updating module, and a timer for obtaining latest contact person information orderly and periodically from the contact person information updating module according to the contact person queue to be updated. The invention can update information of all contactpersons in time, so as to meet extended function of the instant communication system; the invention also can reduce network burst load, and improve performance of the instant communication system.

Description

technical field [0001] The invention relates to the technical field of computer and network communication, in particular to a method for updating contact information in instant communication and an instant communication system. Background technique [0002] With the development of network technology, in order to meet the demand of network instant communication, many instant communication systems have appeared at present. Usually, an instant messaging system includes two parts, a server and a client: the server is mainly used to provide instant message storage and forwarding services, and sends instant messages to the client after logging in; the client is mainly used to provide instant message editing and sending services, and services such as receiving, notifying, and displaying instant messages. [0003] Currently, instant messaging systems maintain contact information owned by users. Contact information refers to the name, gender, age and other personal information rela...

AI Technical Summary

Problems solved by technology

However, its disadvantage is that the local client cannot update the information of all contacts in time, so it cannot meet the rich extended functions of instant messaging, such as being unable to find a contact, making calls, sending text messages, etc., or the delay is long, which affects user experience

However, its disadvantages are: a large amount of data exchange, a large network bandwidth occupied by the sudden login, and a large sudden load of the server, which affects the client login performance and memory usage performance.

But its disadvantage is: only part of the contact information is updated in the whole process, and some information may never be updated unless the user needs to view it, which makes the client unable to update all the information of all contacts in time, so it cannot meet the rich requirements. Extended functions of instant messaging, such as being unable to find a certain contact, making a call, sending a text message, etc., or having a long delay will affect the user experience; in addition, this method will have a sudden short-term high when the client logs in. Load, thus affecting the performance of the instant messaging system

This defect restricts the development of instant messaging system applications, thereby affecting the quality of use of users
