Problems solved by technology

[0003] At the same time, there are also some defects and deficiencies in the existing technology, such as the limited uplink data transmission rate, which is not suitable for long-distance data transmission with high logarithmic rate and real-time requirements, which is related to the internal system hardware performance and external wireless platform bandwidth
When the data transmission rate priority mode is selected, in order to maintain the high-speed real-time data transmission, there will be a little packet loss during the data transmission process, which is unavoidable in the existing technology, but the overall stability and reliability of its performance will not be affected.

Embodiment Construction

[0015] The present invention will be further described in conjunction with the accompanying drawings.

[0016] figure 1 : Describe the protocol stack structure of the wireless transparent D2D technology. The General Packet Radio Service GPRS specification of European Union ETSI stipulates that the protocol stack of the GPRS support node gateway is a way for IP general transmission to carry all upper-layer application protocols, making full use of all the flexibility based on IP, and loading the common The transmission bearer function completes the data transmission that is truly independent of the data content; and according to the interoperability specification IOS V4.1, the A8 interface of CDMA2000 1X uses general data encapsulation for various user business data, and then transmits it through the IP network. It realizes the transmission independent of user service data; therefore, adopts GPRS / CDMA2000 1X to carry out transmission processing without content analysis for var...
