Background technique

With the development of mobile communication technology, various new services have been launched in the mobile communication network, among which Multimedia Message Service (MMS) provides a non-real-time multimedia communication method based on the store-and-forward mechanism. With MMS, users can send and receive various types of information, including: text, pictures, audio, electronic mail (namely email) and video. The Multimedia Message Service Center (MMSC for short) can implement message storage and forwarding in different ways, including message interaction between mobile terminals and mobile terminals, and between mobile terminals and the Internet. Users can create multimedia messages with the help of digital cameras or Bluetooth technology, and send them to other mobile terminal users through MMSC.

When the Next Generation Network (NGN) uses the Domain Name System (DNS) for number query, in addition to the traditional domain name translation DNS widely used on the IP network, a new type of DNS is also introduced. This new type of DNS uses the Telephone E.164NumberMapping (ENUM for short) protocol to complete the mapping between E.164 numbers and Uniform Resource Identifier (URI for short) addresses, called ENUMDNS.

FIG. 2 is a schematic diagram of a process for realizing MMS terminal-to-terminal in the prior art. As shown in FIG. 2 , the existing process for realizing MMS terminal-to-terminal is as follows:

(1) The sending terminal sends a multimedia message, and the multimedia message arrives at the WAP gateway of the place visited by the sending terminal through GPRS;

(2) the WAP gateway at the place where the sending terminal visits receives the multimedia message, and sends a query request to the sending terminal ENUMDNS by the MMSC URI address provided in the sending terminal;

The sending terminal ENUMDNS returns the home MMSC address of the sending terminal to the sending terminal WAP gateway according to the mobile subscriber international number (MobileStation ISDN, referred to as MSISDN) of the sending terminal;

The WAP gateway at the place where the sending terminal visits establishes a connection with the MMSC according to the MMSC address, and forwards the multimedia message to the home MMSC of the sending terminal;

(3) the belonging MMSC of the sending terminal queries the ENUMDNS of the receiving terminal according to the MSISDN of the receiving terminal, obtains the belonging MMSC address of the receiving terminal, and forwards the multimedia message to the belonging MMSC of the receiving terminal according to the corresponding address;

The belonging MMSC of the receiving terminal judges the receiving terminal type: if the receiving terminal is an MMS terminal or an unknown terminal, then send a short message to the multimedia message center to push a "PUSH" message, and perform step (4); if the receiving terminal is a non-MMS terminal , then forward the PUSH message to the Monternet Album system, and perform step (6); if the receiving terminal is an MMS terminal or an unknown terminal and fails to extract the multimedia message within 2 hours, forward the PUSH message to the Monternet Album system , and perform step (6);

(4) The PUSH message arrives at the short message center connected to the home MMSC of the receiving terminal, and the short message center forwards the PUSH message to the receiving terminal according to the user number of the receiving terminal;

(5) The receiving terminal is automatically connected to the MMSC belonging to the receiving terminal according to the PUSH message, and extracts the multimedia message;

(6) The home MMSC of the receiving terminal forwards the multimedia message to the Monternet album system; and, the home MMSC of the receiving terminal can reserve the multimedia message for the MMS terminal or an unknown terminal for 48 hours, within 48 hours, the receiving terminal can receive the multimedia message from its home Extract the multimedia message on the MMSC; meanwhile, the receiving terminal user can also perform step (8);

(7) Montnets album system receives multimedia messages, immediately generates a short message notification, sends it to the SMS gateway where Montnets album is located, and sends it to the receiving terminal through the SMS gateway and the SMS center belonging to the receiving terminal;

(8) Receiving terminal users can log in to the Monternet album system and browse multimedia messages in the Monternet album.

In the process of implementing the present invention, the inventor found that there are at least the following problems in the multimedia message flow in the prior art:

1. The process is complicated, and many steps are required to complete the sending and receiving of multimedia messages;

2. There are many devices, and many devices need to go through in the middle, such as the ENUMDNS of the receiving terminal and the sending terminal, WAP gateway, visiting place, belonging place, etc., which increases the investment cost;
