Problems solved by technology

[0005] But if user 1 and user 2 belong to the same MMSC, let the MMSC be MMSC A and user 3 belongs to another MMSC, let the MMSC be MMSC B, since the MMS setting is the home service, the call forwarding settings of user 1 and user 2 are in MMSC A is completed, and the call transfer setting of user 3 is completed in MMSC B. MMSC A cannot know the call transfer status of user 3, and MMSC B cannot know the call transfer status of user 1 and user 2, so it cannot detect the call transfer loopback and cause death cycle situation
[0006] In order to avoid the infinite loop caused by the call forwarding loopback, the existing technology restricts the call forwarding settings, only allowing the call forwarding service to be set between users belonging to the same MMSC, and prohibiting call forwarding to external Users Covered by MMSC
Although using this restriction avoids the infinite loop caused by the call forwarding loopback, the call forwarding service can only be carried out within the MMSC, which limits the development of the service

Embodiment 1

[0036] Suppose the distribution of users is figure 2As shown, assume that user 1 is the original recipient of the MMS message, and user 1 sets the call forwarding to 2, and user 2 sets the call forwarding to 3. After receiving the MMS message sent to user 1, MMSC A parses the multimedia message received User (User 1) address, and query the call forwarding settings of User 1. Since User 1, User 2, and User 3 all belong to MMSC A, and their call forwarding settings are all completed in MMSC, MMSC A knows that the final receiving user of the MMS is User 3, and sends the MMS message to the user according to the call forwarding settings 3.

Embodiment 2

[0038] Suppose the distribution of users is figure 2 As shown, it is assumed that user 1 is the original recipient of the MMS message, and user 1 sets call forwarding to 3, and user 3 sets call forwarding to 4. After MMSC A receives the MMS message sent to user 1, it learns that the receiving user of the MMS message is user 4 who is not in the MMSC according to the call forwarding settings query of user 1, user 2, and user 3, and obtains the MMSC where user 4 is located The system address of B, according to the MMS specification of the third generation cooperation project (Third Generation Partnership Project, referred to as 3GPP), the MMS message is sent to the requested In the form of forwarding the MMS message to the MMSC B where user 4 is located.

[0039] The difference from the prior art is that the present invention adds an information element for identifying whether the MMS is a call forwarding service in the forwarded MMS message, and values ​​the information elemen...

Embodiment 3

[0044] Assuming that user 1 is the original recipient of the MMS message, and user 1 sets the call forwarding to 3, and user 3 sets the call forwarding to user 4 as an example, the method for sending the MMS message will be described.

[0045] image 3 It is a schematic diagram of the sending process of the method in this embodiment, as shown in the figure, including the following steps:

[0046] Step S301: MMSC A receives the MMS message sent to user 1.

[0047] Step S302: MMSC A inquires about user 1's call forwarding service.

[0048] After receiving the MMS message sent to user 1, MMSC A learns that the call transfer of user 1 is transferred to user 3, and the call of user 3 is transferred to user 4 according to the call transfer service query of user 1.

[0049] Step S303: Determine whether the call is forwarded to outside MMSC A, if yes, execute steps S304 and S305; otherwise, perform call forwarding service processing according to the call forwarding service processin...

Abstract

The invention discloses a method for sending a multimedia message, comprising the following steps: a multimedia service center receives a multimedia message, and if the receiving user of the multimedia message has set a call forwarding service of the multimedia message service, carries the said multimedia message in the multimedia message call transfer service information, and send the multimedia message; the multimedia service center receives the multimedia message sent by the external multimedia service center, and detects whether there is a call transfer loopback possibility according to the call transfer service information, and if so, stops sending the multimedia message described multimedia messages. The invention realizes that when the call forwarding service set by the user is transferred to an external MMSC, the infinite loop caused by the call forwarding loop is eliminated, the call forwarding service is not limited to the MMSC, and the call forwarding service is greatly expanded.

Description

technical field [0001] The invention relates to a communication system, in particular to a method for sending multimedia messages. Background technique [0002] Multimedia Messaging Service (MMS for short) is a service developed under the conditions of mobile network development to the 2.5th generation and mobile terminals tending to be intelligent and multimedia. The length of MMS messages can reach 30-100 kilobytes . In addition to text, an MMS message may contain one or a combination of media formats among audio, picture and video clips. The richness of information content can make the forms of communication between users diverse, and also provides space for content providers to develop mobile value-added services. In the coming 3G (Third Generation Partnership Project) era, MMS is bound to become an essential service for most 3G mobile terminals just like text messages in the 2G era. [0003] Like voice call forwarding, call forwarding is a supplementary service of MM...
