Abstract

A method includes receiving, in at least one broadcast receiving period, a broadcast packet sent by another terminal; determining, according to the broadcast packet sent by the another terminal, a channel environment parameter of an area in which the terminal is located, where the channel environment parameter includes packet time density and/or a packet sending success rate; and determining, according to the channel environment parameter, a sending frequency for sending a broadcast packet in a broadcast sending period after the at least one broadcast receiving period by the terminal.

First claim

What is claimed is:

1. A method for controlling a broadcast packet sending frequency of a first terminal, the method comprising:
receiving, by the first terminal, in at least one broadcast receiving period, a first broadcast packet sent by a second terminal;
determining, by the first terminal according to the first broadcast packet, a channel environment parameter of an area in which the first terminal is located, wherein the channel environment parameter comprises at least one of packet time density or a packet sending success rate; and
determining by the first terminal, a first sending frequency according to the channel environment parameter, wherein the first sending frequency is for sending a second broadcast packet in a broadcast sending period after the at least one broadcast receiving period.

2. The method of claim 1 , wherein the channel environment parameter comprises only the packet time density, wherein determining the first sending frequency comprises:
using, as the first sending frequency, a sending frequency higher than a second sending frequency when the packet time density is less than a first density threshold; and
using, as the first sending frequency, a sending frequency lower than the second sending frequency when the packet time density is greater than a second density threshold, wherein the second sending frequency is for sending a third broadcast packet in a broadcast sending period before the at least one broadcast receiving period, and wherein the first density threshold is less than the second density threshold.

3. The method of claim 1 , wherein the channel environment parameter comprises only the packet sending success rate, wherein determining the first sending frequency comprises:
using, as the first sending frequency, a sending frequency higher than a second sending frequency when the packet sending success rate is greater than a first success rate threshold; and
using, as the first sending frequency, a sending frequency lower than the second sending frequency when the packet sending success rate is less than a second success rate threshold, wherein the second sending frequency is for sending a third broadcast packet in a broadcast sending period before the at least one broadcast receiving period, and wherein the first success rate threshold is greater than the second success rate threshold.

4. The method of claim 1 , wherein the channel environment parameter comprises the packet time density and the packet sending success rate; and determining the first sending frequency comprises:
using, as the first sending frequency, a sending frequency higher than a second sending frequency when the packet time density is less than a first density threshold and the packet sending success rate is greater than a first success rate threshold; and
using, as the first sending frequency, a sending frequency lower than the second sending frequency when the packet time density is greater than a second density threshold and/or the packet sending success rate is less than a second success rate threshold, wherein the second sending frequency is for sending a third broadcast packet in a broadcast sending period before the at least one broadcast receiving period, and wherein the first density threshold is less than the second density threshold, and the first success rate threshold is greater than the second success rate threshold.

5. The method of claim 1 , wherein determining the first sending frequency comprises:
determining, according to a frequency parameter carried in broadcast packets sent by each of a plurality of other terminals, a third sending frequency for sending a third broadcast packet by each of the plurality of other terminals; and
determining the first sending frequency according to the channel environment parameter, a second sending frequency, and the third sending frequency, and wherein the second sending frequency is for sending a fourth broadcast packet in a broadcast sending period before the at least one broadcast receiving period by the first terminal.

6. The method of claim 5 , wherein the channel environment parameter comprises only the packet time density; and determining the first sending frequency, the second sending frequency, and the third sending frequency comprises:
using, as the first sending frequency, a sending frequency higher than the second sending frequency when the packet time density is less than a third density threshold and the second sending frequency is not higher than the third sending frequency; and
