Abstract

The invention discloses a user off-line detection method and a user off-line detection system. The method comprises: a mobile terminal corresponding to each member in a group sends a heartbeat data packet to a server at a first preset time interval; when the server receives the heartbeat data packet sent by one mobile terminal each time, a user record is established for the mobile terminal sending the heartbeat data packet and counting is started, wherein the user record includes expiration time that is a sum of first current time and second preset time and the second preset time is larger than the first preset time; if the server receives an operation instruction sent by the mobile terminal sending the heartbeat data packet within the expiration time, second current time is obtained and the expiration time is updated by using the second current time, wherein the expiration time is a sum of the second current time and the second preset time; and if the server does not receive a heartbeat data packet or an operation instruction that is sent again by the mobile terminal sending the heartbeat data packet within the updated expiration time, the member is determined to be in an off-line state.

Description

technical field

[0001] The invention relates to the technical field of instant messaging, in particular to a user offline detection method and a user offline detection system. Background technique

[0002] Heartbeat technology is a common and effective means of detecting whether the connection between the terminal and the server is normal. However, because mobile terminal applications are sensitive to traffic and power consumption, and have a relatively large impact on the network operator's communication network, the heartbeat sending cycle of mobile terminal applications is generally designed to be relatively long, usually 100 ~300s, and the server generally does not receive the heartbeat data packet for several consecutive heartbeat cycles (such as 3 to 5 cycles) before determining that the mobile terminal user is disconnected. In this way, it may take 300 to 1500 seconds to completely determine that a mobile terminal user is disconnected by using the heartbeat. That is...
