Abstract
The invention relates to a transmission method of video signals in an unauthorized mobile access network, which comprises the steps that: S1, a call-starting mobile phone end collects the video data of a caller by a camera on the mobile phone and stores the video data into a memory; S2, the video data collected from the caller are taken out from the memory, packed into a standard IP packet and transmitted to a server by network; S3, the video data IP packet of the caller is sent to a call-receiving mobile phone end by the core network by the server; S4, the call-receiving mobile phone end analyzes the received video digital of the caller into the readable video document which is then broadcasted to complete the video signal transmission of the calling process and realize video call. The method of the invention can complete the modification of the existing GPS mobile phone by only requiring a little amount of development and testing work, thus realizing smooth integration from a honeycomb world to an internet world; the mobile phone can transparently support a plurality of public GSM/GPRS services by requiring no modification.
Description
Technical field
The present invention relates to a kind of WLAN WLAN, fixed network and unauthorized move the fusion FMC (fusion of federal maritime commission fixed mobile network) that inserts the UMA technology, more particularly, be about the video-signal transmission method in the UMA network.
Background technology
Current, fixed network and mobile network's integration technology has obtained development at full speed.Can realize at stage construction from the angle fixed network of technology and the fusion between the mobile network, as operation layer, network layer and end side etc.Be put into 3GPP (3 at UMA
RdGeneral partnership project) after the standard, the fusion of end side is especially as hot technology.GSM (the Global systemfor mobile communication global mobile communication) network coverage that uses is wide at present, can guarantee uninterrupted connection the between user and the network, and under the situation of high-speed mobile, also can guarantee stable service quality, but message transmission rate is relatively low.And the coverage of WLAN (wireless local area network WLAN (wireless local area network)) system is little, only is present in hot zones, but the message transmission rate height can be realized broadband access network.Simultaneously, the relative GSM network of the service fee of wlan network is relatively more cheap.Based on this, become possibility by the broadband network transmission video signal, because it provides enough transmission rates, and lower use cost.As long as the mobile phone end is responsible for having collected video acquisition, data preparation and send to network, and the vision signal that receives is shown on screen.
Summary of the invention
As mentioned above, current integration technology is by GSM and GPRS (general packet radioservice GPRS) protocol data being encapsulated the into IP of standard (intemet protocol) bag, and UMA can be provided in the advantage of multiplexing GSM and GPRS agreement on the Internet.Therefore, only need very a spot of development﹠ testing work just can finish modification to existing GSM mobile handset, thus the smooth fusion of realization from the honeycomb to the internet world fast.Mobile phone need not to change and just can support most of public GSM/GPRS services pellucidly, as WAP (wireless application protocol WAP (wireless application protocol)) browse, FTP (file transfer protocol file transfer protocol (FTP)), SMS (simple message service short message service) and Additional Services.Therefore, if the video transmission between the UMA, a video data that only needs to gather encapsulates the IP bag packet of standard into and is sent to network, and the mobile phone of the other end can receive this packet; If the video packets of data transmission between UMA and other network as long as there is the core work net to become mobile phone to support the data format of playing according to type of decomposition the video packets of data that receives, and is play in real time at the screen end, can realize video telephone.
Summary is got up, and the object of the present invention is to provide the video-signal transmission method in a kind of UMA (undelegated mobile access) network.
Technical scheme of the present invention is as follows:
Video-signal transmission method according in a kind of undelegated mobile access network of the present invention comprises step,
S
1, the video data of the mobile phone end of giving orders or instructions by the camera collection caller on the mobile phone, and deposit internal memory in.
S
2, will take out the IP bag that standard will be advanced in encapsulation from internal memory to video data that the caller gathered, by Network Transmission to server,
S
3, server sends caller's video data IP of receiving bag to and receives words mobile phone end by core network,
S
4, receive the words mobile phone and caller's video data of receiving is resolved into its readable video file and play, finish the video signal transmission of communication process, realize video calling.
Particularly, step S
1In, the camera that is used for gathering caller's video data is positioned on the front of the mobile phone of giving orders or instructions;
Described camera is 2 times/second to the frequency acquisition of caller's video data;
Phone system has differentiate to be received the words mobile phone terminal and whether is in step under the unauthorized access network.
If this receipts words mobile phone terminal is under the undelegated mobile access network described step S
3In, this server directly is transmitted to the IP packet by core network and receives the words mobile phone terminal;
If this receipts words mobile phone terminal is not under the undelegated mobile access network then described step S
3In, this server earlier changes into caller's video data these receipts by core network and talks about and be given to this receiver terminal after the data format of the current network of living in of mobile phone terminal is encapsulated into the IP packet again.
Obviously, the inventive method has only needs very a spot of development﹠ testing work just can finish having the modification of GSM mobile handset now, realizes the smooth fusion from the honeycomb to the internet world; Mobile phone need not to change and just can support most of public GSM/GPRS services pellucidly.
Embodiment
One embodiment of the present of invention are as follows:
The give orders or instructions camera collection caller of mobile phone end by the mobile phone front video data, such as the half second collection once, deposit in the internal memory, the video signal data of gathering is encapsulated the into IP bag of standard, arrive server by Network Transmission, server is according to receiving the words mobile phone terminal whether under the UMA network, if, directly packet is transmitted to and receives the words mobile phone terminal by core network, if not at the UMA network, by core network with data change into the current network of living in of this receipts words mobile phone terminal data format, packet is passed to this receipts talks about mobile phone terminal.After this receipts words mobile phone is received packet, resolve into the readable video file of this mobile phone and on screen, play.Reach the video signal transmission in the communication process like this, finished give orders or instructions mobile phone and the video calling of receiving the words mobile phone.
Claims (6)
1, the video-signal transmission method in a kind of undelegated mobile access network comprises step:
