Problems solved by technology

[0012] The existing ALOHA mechanism does not provide an effective solution to the above problems, but simply considers that the multi-slot resources of a node operate independently, and the operation of each time slot is processed as a single time slot. However, this method is not flexible , Effectively process and coordinate multi-slot resources, often there will be some application errors

Embodiment Construction

[0046] Under the MS-ALOHA mechanism in the vehicular communication system, when a node (hereinafter referred to as the first node) occupies multiple time slots at the same time, in order to facilitate resource management, in the embodiment of the present invention, no matter how many time slots the first node occupies For time slots, the first node maintains only one time slot state vector (table) to process receiving and sending messages. This scheme is also called a single-table scheme. For ease of description, assuming there are N time slots in a frame in the system, a possible time slot state vector (table) is as follows Figure 1A Shown.

[0047] In the time slot state vector (table), the time slot state information corresponding to each time slot is stored as a time slot information unit, denoted as Unit, which stores various types of information required in the receiving and sending process.

[0048] On the other hand, in the embodiment of the present invention, the first nod...

Abstract

The invention relates to the communication field, and discloses a method and device of sheet processing for multi-slot resources. The method comprises the following steps: aiming at each slot in a frame period, a first node uniformly maintains slot state vectors in which slot state information of each slot stores, sends FI to other nodes in self-use slot in each frame period, receives FI sent by other nodes in non-self-use slot in each frame period, and updates the slot state information corresponding to each slot in the slot state vectors maintained locally according to the received FI. Therefore, requirements of multi-slot resource operation of car networking multiple business types are met, the multi-slot resources can be effectively processed and coordinated, one slot state vector sheet is adopted to conduct node multi-slot resource processing, the storage capacity is small, the load processing is uniform, and overmuch operating load can not be brought to a system.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a single table processing method and device for multi-slot resources. Background technique [0002] With the development of in-vehicle communication systems and the gradual maturity of mobile ad hoc network technology, in order to realize real-time, dynamic and intelligent management of vehicles, DSRC (Dedicated Short Range Communications) for the Internet of Vehicles has been specially developed internationally. protocol. Through the two-way transmission of information, DSRC organically connects the vehicle with the vehicle, the vehicle and the information collection equipment on the roadside, and supports point-to-point and point-to-multipoint communication. [0003] The mobile slotted Aloha (Mobile Slotted Aloha, MS-ALOHA) mechanism is a DSRC MAC (Medium Access Control; Medium Access Control) layer access and resource allocation mechanism based on the time-sharing method. The r...
