Problems solved by technology
[0004] 1. A VOIP Gateway must be provided at the telecommunications end as a forwarding process. That is to say, if the customer needs to find someone else, he must search on the server 30. If the search is found, perform VOIP forwarding to obtain and assign the other party’s IP. Both parties must be in the online state to perform transmission actions; however, this solution requires a large maintenance and operation cost for the telecom end, because as the number of online connections increases, the corresponding VOI Pgateway must also increase relatively, so The resulting cost is quite high, and considering the action of roaming transmission, the cost will be even more terrible;
[0005] 2. If you use a fixed IP connection, one of the ends must be a fixed IP. This method is more feasible in a network with a fixed IP, such as a dedicated line or broadband DSL, etc., but this method is more difficult in the current mobile telecommunications. Unable to implement peer-to-peer information transfer

The present invention relates to a method for point-to-point transmission of dynamic images and sounds in wireless dynamic IP networks such as GSM / GPRS, which provides image and voice transmission between at least two (two places) handheld electronic devices; When the electronic device at the requesting end wants to transmit audio-visual data to another electronic device, it first sends the IP address connected to the network and related connection information to another electronic device by sending a short message. When the receiving electronic device receives the short message , to confirm whether to receive it, if you want to receive it, keep the IP and related online information transmitted from the other end, and connect to the network to obtain the IP, and connect to the handheld electronic device that originally sent the message through the GSM / GPRS network (eg: Pocket PC Phone), so that related video and audio transmission can be carried out.
Description
technical field [0001] The present invention relates to a technical field of information transmission applied to wireless dynamic IP networks such as GSM / GPRS, in particular to a wireless dynamic IP network that can achieve point-to-point dynamic image and sound transmission without assigning a fixed IP through the server end A method of point-to-point transmission of images and sounds. Background technique [0002] At present, two computers must use IP software addresses for file transmission and information transmission through the network, and the so-called IP is defined in the third layer of OSI, which is the network layer. Since our current network foundation is communicated by IP (Internet Protocol), since this IP is given by the software of the operating system, it is also called a software address (software address), which is composed of four groups of 8bits numbers , for example, the IP address of tw.yahoo.com is: 202.1.237.21. Basically, the transmission behavior...
