Abstract

An implementing method for removing duplication protection for multimedia messaging service interworking forwarding message and multimedia messaging service interworking gateway. The method determines whether to return response message according to the different value of the acknowledgement request field of the request signaling. Using the SMTP-interactive-status code as a criterion, when the acknowledgement request field is set to be “NO”, requesting not to return the response message, and when the acknowledgement request field is set to be “YES”, requesting to return the response message. Determine whether the forwarding is successful by determining whether the SMTP-sending-status code returned by the response signaling is received according to the replying status of the response signaling.

Claims

1. An implementing method of removing duplication protection for a multimedia messaging service interworking forwarding message, including:

A, an original Multimedia Messaging Service Interworking Gateway (MMSIG) sending information to a recipient MMSIG at an opposite end, wherein the information is a forwarding message request;

B, the recipient MMSIG determining a transmission type of a link according to a setting status of a request signaling of the original MMSIG, and determining whether the message is successfully received according to a status-identification code fed back by the request signaling or a response signaling, if successfully received, then going to step C, if not successfully received, then returning to step A; and

C, delivering normally received information to a Multimedia Messaging Service Center (MMSC).

2. The method according to claim 1, wherein

when the recipient MMSIG determines the original MMSIG transmits information on a single link, the recipient MMSIG determines a receiving status of the information according to the status-identification code fed back by the request signaling.

3. The method according to claim 2, wherein in the single-link transmitting information mode, an acknowledgement request field in the request signaling is set to be “

NO”

, requesting not to return the response signaling, and the SMTP-interactive-status code of the request signaling is used as a status feedback of message processing.

4. The method according to claim 3, wherein the SMTP-interactive-status code is “

250 OK”

.

5. The method according to claim 1, wherein

when the request signaling of the original MMSIG and the response signaling of the recipient MMSIG are transmitted on double links, the recipient MMSIG determines a receiving status of the information according to the status-identification code fed back by the response signaling.

6. The method according to claim 5, wherein in the double-link transmission mode, an acknowledgement request field in the request signaling is set to be “

YES”

, requesting to return the response signaling, and the SMTP-interactive-status code of the response signaling is used as a status feedback of message processing.

7. The method according to claim 6, wherein the interactive-status code of the response signaling is “

250 OK”

.

8. An MMSIG, for removing duplication protection for a multimedia messaging service interworking forwarding message, the MMSIG being respectively used as an originator or a receiver, connecting to an MMSC, and being set as follows:

when the MMSIG is used as an originator, the original MMSIG sets the status of a request signaling and sends information to an opposite MMSIG used as a receiver, wherein the information is a forwarding message request;

thus the recipient MMSIG determines a transmission type of the link of the MMSIG according to a setting status of the request signaling of the MMSIG, and determines whether the information is successfully received according to a status-identification code fed back by the request signaling or a response signaling, if successfully received, the normally received information will be delivered to the MMSC; and

when the MMSIG is used as a receiver, the recipient MMSIG receives the information sent by an opposite MMSIG used as an originator, determines the transmission type of the link of the original MMSIG according to the setting status of the request signaling of the original MMSIG, and determines whether the information is successfully received according to a status-identification code fed back by the request signaling or the response signaling, if successfully received, the normally received information will be delivered to the MMSC.

9. The MMSIG according to claim 8, wherein the MMSC is also connected to user terminals, and the MMSIG is used to determine whether the information delivered by the MMSC has been successfully read by users according to the SMTP-interactive-status code fed back by the user terminals.
