Method for delivering cpm messages and server thereof

Abstract

Disclosed is a method for delivering a message in a converged IP messaging (CPM) server. The message delivery method may include determining whether to reject a CPM message based on the access policy if the CPM messageis is received; checking a user preference of a target terminal to determine processing of the CPM message if it is determined that the CPM message is not rejected; determining whether to reject, defer or store the CPM message based on the user preference if the target terminal is not registered or in an unreceivable state; storing the CPM message in a queue if it is determined that a transmission of the CPM message is deferred; determining whether to discard or store the CPM message based on the user preference if a timer for the CPM message is expired; requesting to store the message to a message storage server if it is determined to be stored; receiving a response message including information on the stored message from the message storage server; and transmitting a message including the information on the store message to the terminal.

Description

technical field [0001] The present invention relates to Convergent IP Messaging (CPM) services. Background technique [0002] Nowadays, there are various services for transmitting and / or receiving messages through portable devices, such as SMS, MMS, email services, and the like. [0003] In the system for providing SMS service and MMS service generally used in this way, there is no server for storing user messages. Alternatively, if the user's terminal becomes incapable of receiving a message, such as a shutdown of the terminal, the server in charge of temporarily transmitting the message stores the message. Then, if the user terminal returns to a situation where messages can be received, the temporarily stored message is transmitted. However, the server responsible for transmitting messages is not initially intended for storing messages, and therefore it only stores messages for a predetermined period of time, and then deletes the messages when the storage capacity become...

AI Technical Summary

Problems solved by technology

[0030] However, since the message has been deleted in its own storage, the CPM PF server 81B cannot process the requested message transmission, and therefore, will transmit a failure message to the terminal B1 10B (S40)

[0031] In addition, there is no method for checking whether a message is stored in the message storage server 60, and therefore, there is a problem that the terminal B 110B cannot acquire the message
