The car connected network communication system of vehicle active safety has higher requirement to communication delay, therefore generally all adopts the self-organization network technology of short-range communication.At present at car networking arenas, according to the form that Radio Resource uses, mainly contain two class self-organization network technologies, a kind of is special short-distance wireless communication (DSRC) technology based on IEEE802.11p, and this is the self-organizing network of asynchronous communication; The synchronous communication self-organizing network that another kind is is representative with mobile CDMA slotted ALOHA (MS-ALOHA).

In self-organizing network, each terminal all needs to communicate, but the strange mutually and dynamic change of each terminal, be ensure fail safe, all need to comprise no small security information data in each data that each terminal sends; Also the information such as sending time slots takies are needed for adopting MS-ALOHA self-organizing system machine-processed like this.These all decrease the traffic volume of useful load data, affect very much the efficiency of communication link, are also unfavorable for the expansion of communication function.

In cell mobile communication systems, terminal transmits and receive data all under the control of a network, by grid distributing radio resource, and by network delivery data.For meeting specific communication requirement, 3GPP has also carried out discussion and the research of device-to-device (DevicetoDevice, D2D) communication service.

For 3GPPD2D technology, mainly utilize distributed frequency spectrum band in part, a small amount of terminal can activate D2D business, and the terminal of car networking all needs to distribute frequency spectrum resource, the characteristic of 3GPPD2D technology is different from the demand of car working application, and therefore in vehicle network communication system, the allocation of radio resources mode of terminal directly cannot use for reference the allocation of radio resources mode of terminal in 3GPPD2D technology.

Visible, need to seek a kind of terminal resource distribution method for car connected network communication system.
