Problems solved by technology

[0005] It can be seen that in the prior art, since the VP service is a data bearer service, there is no corresponding process to notify the calling user of the cause of the service failure. Therefore, when the VP service fails, the calling user cannot be informed of the failure The reason for the failure of the secondary service reduces the user's trust in the VP service and reduces the user's satisfaction with the VP service

Embodiment 1

[0060] Referring to Figure 2, in this embodiment, the following steps are required to implement the present invention:

[0061] Step 201: the calling UE sends a SETUP to the 3G MSC, and the BC_IE in the message is 64K UDI, indicating that it is a videophone service call;

[0062] Step 202: the 3G MSC sends a CALL PROCEEDING message to the calling UE to notify the calling UE to continue the VP calling process;

[0063] Step 203: the 3G MSCA initiates an assignment request (RABAssignment) message to the access network RNC where the calling UE is located, and after receiving the message, the access network RNC establishes a radio bearer connection with the calling UE;

[0064] Step 204: After the radio bearer of the calling UE and the RNC where the calling UE is successfully established, the RNC returns an assignment response (RAB Assignment Rsp) message to the 3G MSC to notify the 3G MSC that the calling UE and the radio bearer where the RNC is located are successfully establish...

Embodiment 2

[0084] When the BICC protocol is adopted, the implementation process and each message in the process are similar to those of the first embodiment shown in FIG. 2 , the only difference is that each ISUP in the message name is changed to BICC; The process shown in 2 is similar, therefore, the embodiment using the BICC protocol will not be described in detail;

Embodiment 3

[0086] When the PRA protocol is used, its implementation process is shown in Figure 3. In this process, each step is similar to the step shown in Figure 2, and the difference is only in the steps 306, 307, 309, and 310. The adopted signaling message is the message in the PRA protocol, specifically:

[0087] Step 306: The 3G MSC judges, according to the identified failure cause, whether the calling user needs to be played when the VP call fails, if not, terminate the process; if so, the 3G MSC sends a PRA SETUP to the streaming media playback platform message to notify the streaming media playback platform to notify the call failure reason by playing audio and video files to the calling user; wherein, in this message, the calling number is the number of the calling UE, and the called number is "specific service code + called "ISDN", through this specific service code, to notify the streaming media playback platform to play audio and video files to the calling user to notify the...

Abstract

Present invention discloses a method for notifying service failing reason in picture phone service. It contains A, 3 G mobile switching center ( MSC ) judging whether calling is failing, if is , then identifying failing reason and execution step execution step B, B, G MSC transmitting said failing reason to failing reason playing net element, C, failing reason playing net element determining correspondent audio video media stream file according to received failing reason proceeding negotiation with dialing user, utilizing established loading channel after negotiation to play said correspondent audio video media stream file to dialing user.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a method for notifying the cause of service failure in a videophone service. Background technique [0002] At present, the third generation (3G) network is gradually developing. The video telephony (VP) service supported by the 3G network circuit domain is based on the ITU-T H.324M technology. Video services are further provided, therefore, better end-to-end user experience can be provided compared to traditional voice services. The VP service has developed into one of the killer services that differentiate 3G networks from second generation (2G) networks. [0003] From the perspective of the development of protocol standards, the VP service, like the fax service, is also a data bearer service. However, the traditional data bearer service does not need to play the caller's failure announcement. Therefore, so far, there is no service for the VP service. The pr...
