In the path choice of the mobile query,both the restraint relation and the network characteristic have the tremendous influence to the path choice.We propose a new path choice of mobile query method according to this characteristic.At first,this method decomposes a query into several sub-inquiries and combines several paths according to the constraint condition,then estimates the tuple size of these paths,finally finds the superior path through the path choice algorithm in these paths.This method fully considers the two factors which are the restraint relation and network characteristic.The experiment indicates that this method can obtain the superior path in these paths.
