Processing method of off-line message and instant information server

Abstract

A method for processing deferred messages includes a storing process, a notification process and a retrieving process. In the storing process, when a user presets and requires to store the deferred message, the system stores the deferred message to be sent to the user; in the notification process, when a user gets online, an IM server at the client side detects the system has stored the deferred message for the user and if the user has subscribed the deferred message notification, the system sends the deferred message notification to the client according to the setting of the system or of the user; in the retrieving process, when the client receives the deferred message notification and requests to acquire the deferred message, its IM server sends the deferred message content to the client. The present invention improves the method for processing deferred messages in the SIP / SIMPLE IM service system.

Description

technical field [0001] The invention relates to the communication field, in particular to a session initiation protocol SIP / instant message and an offline message processing method in an instant message system using the extended session initiation protocol SIMPLE and an instant message server. Background technique [0002] In the prior art, instant messaging (Instant Messaging, IM) services have been carried out on mobile communication networks and Internet (Internet) networks. Mobile networks include the existing 2G (2nd Generation, 2nd generation mobile network), 2.5G, and future 3G (3rd Generation, 3rd generation mobile network), and multimedia subdomain (IMS). [0003] The instant message service belongs to a type of mobile data service based on a presence service (Presence), which is an individual-to-individual, individual-to-group message type. [0004] The Open Mobile Alliance (OMA) international standards organization has formulated standards for mobile instant mess...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, the instant messaging system conforming to the SIP / SIMPLE IM standard only involves offline message storage technology and notification technology, but does not involve offline message storage and acquisition subscription technology, offline message acquisition technology, and how users choose The technology of obtaining one or more messages, the technology of sending multiple messages, etc., that is, the existing technology does not provide a complete offline message solution

[0007] In addition, in the existing OMA SIMPLE IM standard specification, it is described that offline messages should be stored in an offline message storage database (deferred message storage database), but actually the content and metadata (meta-data, similar to summary data) of offline messages Not all must be stored in this offline message storage database; for the notification technology, the existing specification describes the use of SIP MESSAGE messages to carry offline message notifications, but for the content in the notification, the way of sending the notification (such as a one-time delivery or issued one by one) and so on, there is no clear research
