Description

A message sending method and system thereof

technical field

The invention relates to the technical field of mobile communication, in particular to the technical field of message sending in the mobile communication system.

Background technique

In recent years, with the development of communication technology, various value-added services, especially message services, have achieved tremendous development in the world. Message services include various types, such as Short Messaging Service (SMS), Enhanced Messaging Service (EMS), Multimedia Messaging Service (MMS), Instant Messaging (IM), etc. , most message services are non-real-time store-and-forward services. Message service has become one of the most important ways for value-added service providers to provide services to users, such as sending user-booked weather information, securities information, sports news and so on.

At present, message services can be divided into non-real-time messages and real-time messages. Non-real-time messages are commonly referred to as store-and-forward messages, including SMS, EMS, MMS, etc. Real-time messages are non-store-and-forward messages. IP Multimedia System (IP Multimedia System IP, IMS) implementation, including instant messaging and session-based messaging. IMS uses the initialization protocol (Session Initiation Protocol, SIP). The real-time message service transmits the specific message content through the SIP message (Session Initiation Protocol Message). The message can include a variety of media, such as characters, pictures, visual images, and sounds. Instant messaging means that the sender performs real-time message transmission without the need for the two parties to establish a reliable connection first. Session-based messaging refers to the establishment of a reliable connection between the two parties first, and then message transmission.

Currently, for store-and-forward messages such as SMS, EMS, MMS, etc., when the receiver of the message is unreachable or the network is not normal, the message will be stored in the message center. When the receiver is reachable or the network is normal, the message center will send the message as soon as possible. sent to the recipient. The message center includes short message center, enhanced message center, multimedia message server and so on.

However, for real-time messages such as IM and session-based messages, the network does not provide the store-and-forward function. When the receiver of the message is unreachable or the network is abnormal, the message sending will fail. Real-time messages include two situations: point-to-point message transmission and message services involving multiple parties, where messages involving multiple parties include point-to-multipoint messages and multi-party message conferences.

Under the existing technology, when the user sends a message, the terminal can only choose to send the message through a messaging mechanism, such as SMS, MMS, IM, etc., when the real-time messaging mechanism is selected, if the receiver is unreachable , the message sending will fail and the network will not save the message. If the user wishes to change the real-time message to a store-and-forward type message for message transmission when the real-time message transmission fails, active intervention of the user is required and cannot be realized automatically. That is, when the user first sends a real-time message through the terminal, due to reasons such as the receiver being unreachable, the user is notified that the message sent by the network fails to be sent, and then the user sends a store-and-forward message again, and the content of the message remains consistent. This method is not flexible enough for users, and due to repeated message sending, it increases the burden on the network.

Contents of the invention

The purpose of the present invention is to provide a method for automatically converting real-time messages into store-and-forward messages, which solves the problem that real-time messages cannot be automatically converted into store-and-forward messages for sending when the user fails to send real-time messages; at the same time, The present invention provides a system that can implement this method.

The present invention provides a method for sending a message, the message is a real-time message, comprising the following steps:

a. The message sending terminal sends a real-time message, and carries an instruction to change the message transmission form in the real-time message that needs to change the transmission form;

b. After receiving the real-time message, the network side sends the real-time message to the message receiving terminal. If the sending is successful, the real-time message service is terminated. If the sending fails, the network side identifies whether the real-time message carries an instruction to change the message transmission format. , if it carries the instruction to change the message transmission format, then go to step c, if it does not carry the instruction to change the message transmission format, end the real-time message service;

c. The network side judges whether it supports converting the real-time message into a store-and-forward message, and if so, converts the real-time message into a store-and-forward message for transmission, and returns transmission failure information to the sending terminal if it does not support it.

After receiving the transmission failure information from the network, the message sending terminal judges whether it supports retransmission after changing the message transmission mechanism; if so, the terminal ends the real-time message service and resends the message through store and forward; if not, ends the message transmission Describe the real-time messaging service.

The real-time messages include instant messages and session-based messages, and the store-and-forward messages include MMS, EMS, SMS, and the like.

The content of the store-and-forward message is consistent with that of the real-time message.

The instruction to change the message transmission form can be realized by adding a new parameter to the initialization protocol message, or a special value can be set in the parameter of the initialization protocol message that indicates the effective time of the message to represent the instruction to change the message transmission form.

In the method of the present invention, real-time messages can be converted into store-and-forward messages through the message interworking gateway.

In the method of the present invention, before identifying whether there is an instruction to change the message transmission format, the network side judges whether the message sending failure is caused by the receiver being unreachable or the network is abnormal, if not, then end the real-time message service, if yes, then identify Whether to carry the indication of changing the message delivery format.

In the method of the present invention, the receiver being unreachable includes that the receiver is turned off, the receiver is not in the service area, and the like.

In the method of the present invention, the network abnormality includes network congestion, network equipment failure and the like.

The present invention also provides a message sending system, including a sending terminal, a sending network, a receiving terminal, and a receiving network, wherein the sending terminal sends the real-time message to the sending network, and the sending network sends the real-time message sent by the sending terminal. To the receiver network, the receiver network sends the real-time message sent by the sender network to the receiving terminal, and the system also includes a message interworking gateway, which supports converting the real-time message into a store-and-forward message; when the network When sending a real-time message fails, the network detects whether the real-time message carries an instruction to change the message transmission format, and if so, converts the real-time message into a store-and-forward message through the message interworking gateway for transmission.

The present invention proposes a method for automatically converting real-time messages into store-and-forward messages and a network for implementing this method. When a user sends a real-time message, if the message fails to be sent, the network can automatically convert the real-time message into a store-and-forward message; The whole process is realized automatically through the network without the active intervention of the user. This method brings great convenience and flexibility to the user to apply the message service, and in the case of automatic network switching, the message does not need to be resent completely twice, reducing the network load of the operator.

If the network does not support the conversion of real-time messages into store-and-forward messages, the message sending failure information will be returned to the terminal, and the terminal will automatically resend the message through store-and-forward messages after receiving the message sending failure notification from the network. In this case, it still brings great convenience and flexibility to the user to apply the message service, and in the case of automatic terminal switching, no user intervention or manual operation is required, which provides convenience to the user.
