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.

Claims

1. A method for processing deferred messages, applicable in an instant message (IM) system under Session Initiated Protocol (SIP) and Instant Message and Presence Leveraging Extensions (SIMPLE), the method comprising:

storing, by the IM system, deferred messages to be sent to a user, where the deferred messages comprise meta-data and content, the meta-data is stored in an IM Extensible Markup Language Document Management Server entity (IM XDMS entity) and the content is stored in a deferred message content storage entity;

notifying of the deferred messages, comprising determining there are deferred messages for the user stored in the IM system associated with a client of the user when the user gets online, and sending a deferred message notification to the client of the user; and

retrieving the deferred messages, comprising sending the deferred messages to the client by an IM server in response to a request from the client for retrieving the deferred messages after the client receives the deferred message notification.

2. The method according to claim 1, wherein the deferred message notification comprises deferred message list information and the meta-data.

3. The method according to claim 1, wherein if the user subscribes the deferred message notification, the deferred message notification is sent in a SIP NOTIFY message;

otherwise, the deferred message notification is sent in a SIP MESSAGE under default setting of the IM system.

4. The method according to claim 3, wherein sending the deferred message notification comprises:

sending, by the IM system, the deferred message notification at a set time or periodically or once only after the client gets online.

5. The method according to claim 1, wherein the deferred message notification comprises deferred message list information and deferred message meta-data or deferred message content.

6. The method according to claim 1, wherein if the user subscribes the deferred message notification, when the client gets online, the IM server queries and retrieves the deferred message meta-data for the user from the IM XDMS entity through an IM-3 interface;

and then the IM server constructs a deferred message list in accordance with a query result and sends the deferred message notification to the client of the IM server by a SIP NOTIFY message carrying the deferred message list and the deferred message meta-data.

7. The method according to claim 1, wherein if the user does not subscribe the deferred message notification, when the client gets online, the deferred message meta-data for the user is retrieved from the IM XDMS entity through an IM-3 interface;

and then a deferred message list in accordance with a query result is constructed and the deferred message notification is sent to the client of the IM server carrying the deferred message list and the deferred message meta-data.

8. The method according to claim 1, wherein after the IM server sends the deferred message notification to the client, the IM server receives a deferred message retrieving request which carries a retrieving condition from the client and the IM server sends the deferred message content to the client under the retrieving condition.

9. The method according to claim 8, wherein the client initiates the deferred message retrieving request through a SIP message, an HTTP message or a Message Session Relay Protocol (MSRP) message in an MSRP channel.

10. An instant message (IM) server for processing deferred messages, applicable under Session Initiated Protocol (SIP) and Instant Message and Presence Leveraging Extensions (SIMPLE), the IM server comprising:

a storage entity configured to store deferred messages to be sent to a user, where the deferred messages comprise meta-data and content, and the meta-data and content are stored separately in different storage entities in the step of storing the deferred messages, the meta-data is stored in an IM Extensible Markup Language Document Management Server entity (IM XDMS entity) and the content is stored in a deferred message content storage entity;

a notification entity configured to determine there are deferred messages for the user stored in the IM server associated with a client of the user when the user gets online, and sending a deferred message notification to the client of the user; and

a retrieving entity configured to send the deferred messages to the client by the IM server in response to a request from the client for retrieving the deferred messages after the client receives the deferred message notification.
