Problems solved by technology

[0005] The defects of the above method are: 1. Due to the restriction of the mobile network technology system, the bandwidth of the CS domain is only 64Kbps, although the quality of service (QoS: Quality of Service) of the transmission signal can be guaranteed, it cannot meet the real-time requirements of large bandwidth and high-definition images. Transmission; 2. Since monitoring is implemented based on VP calls, a direct connection is established between the user terminal and the monitoring point. One video source cannot support multi-point image transmission at the same time, and is only suitable for simple point-to-point services; 3. All The mobile terminal used needs to support a specific CS domain video transmission protocol (currently H.324 / M), which is not conducive to the compatibility of various terminal types and limits the promotion of business use
[0019] The disadvantage of the above method is that: compared with the monitoring service usage method (dial-up) in the circuit domain, the user terminal operation is more cumbersome, the user experience is not good, and it is not conducive to the promotion and use of the service

Embodiment 1

[0054] Embodiment 1, a mobile monitoring method, the process is as follows figure 1 shown, including:

[0055] A1. The call control center receives the call request initiated by the user terminal;

[0056] In the present invention, in order to facilitate the user to use the mobile monitoring service, a specific special service number is used to correspond to the corresponding monitoring point, and the user only needs to initiate a call request to the number when using the service. Commonly used user terminals are multimedia mobile phones, and personal computers (PC: Personal Computer) and personal digital assistants (PDA: Personal Digital Assistant) can also be used as user terminals if they have corresponding communication functions.

[0057] A2. The call control center analyzes the called number in the user call request, and routes the call request to the gateway device when judging that the called number is a special service number corresponding to the monitoring service; ...

Embodiment 2

[0114] Embodiment 2, a mobile monitoring method, the process is as follows image 3 As shown, the method of this embodiment is basically the same as that of Embodiment 1, the difference is that in this embodiment, the gateway device forwards the monitoring media stream to the user terminal through the PS domain, so the audio and video coding is no longer converted during the interaction , it only needs to complete the conversion of the signaling level and translate the user's key information. The process includes:

[0115] B1. The call control center receives the call request initiated by the user terminal;

[0116]B2. The call control center analyzes the called number in the user call request, and routes the call request to the gateway device when judging that the called number is a special service number corresponding to the monitoring service;

[0117] B3. The gateway device establishes the association between the special service number and the network address information...

Embodiment 3

[0124] Embodiment 3, a mobile monitoring method, the process is as follows Figure 4 As shown, the difference between the method in this embodiment and Embodiments 1 and 2 is that in this embodiment, the gateway device does not connect after completing the corresponding conversion from the special service number to the URL of the media server, but the user terminal uses the URL of the media server to Initiate access requests directly from the PS domain to obtain real-time monitoring media streams. The process includes:

[0125] C1. The call control center receives the call request initiated by the user terminal;

[0126] C2. The call control center analyzes the called number in the user call request, and routes the call request to the gateway device when judging that the called number is a special service number corresponding to the monitoring service;

[0127] C3. The gateway device establishes an association between the special service number and the network address inform...

Abstract

The key idea is: using the gateway to convert the address of media server corresponding to phone number dialed by user terminal, and the dialing information of user is correlated with the address information of media gateway such that user can use the supervision service simply using number's dialing. The method provides multi approaches for supervising the media stream transmission from the media gateway to user's terminal, which comprises: the media gateway relays the media stream from CS domain; the media gate relays the media stream from PS domain; users get the media stream directly from the PS domain. The also provides relevant gateway and supervision system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile monitoring method, gateway equipment and a monitoring system. Background technique [0002] Mobile surveillance is a service that provides users with audio and video media data stream services based on mobile networks. Users can watch the encoded streaming media through the mobile terminal, so as to grasp the situation of the designated monitoring point in real time. The existing mobile monitoring technology mainly has the following two implementation schemes: [0003] 1. Video surveillance based on circuit switched domain (CS: Circuit Switched) [0004] This solution is mainly based on the video phone (VP: Video Phone) function of the mobile network, and a special phone number is bound to each monitoring point. When the user uses the monitoring service of the CS domain, his experience is the same as that of a normal phone call. He only needs to dial the specia...
