  • 摘要: 針對(duì)當(dāng)前垂直切換判決算法存在的單一性,即切換判決時(shí)以用戶或網(wǎng)絡(luò)單方面為中心,沒有充分考慮兩者對(duì)切換判決的綜合影響,導(dǎo)致垂直切換性能不佳的問題,該文提出一種基于雙向匹配模型的垂直切換算法。該算法的主要思想是:首先分別以用戶和網(wǎng)絡(luò)為中心,設(shè)計(jì)各自的評(píng)估模型,用于評(píng)估雙方對(duì)彼此的偏好順序,并建立相應(yīng)的排序值矩陣;其次利用排序值信息,基于一對(duì)多雙向匹配模型對(duì)用戶側(cè)和網(wǎng)絡(luò)側(cè)的雙向匹配行為進(jìn)行建模和求解,以獲得最優(yōu)匹配解;最后根據(jù)最優(yōu)匹配結(jié)果,進(jìn)行垂直切換。仿真表明,該文設(shè)計(jì)的評(píng)估模型是合理的,并且所提出的算法能較好地兼顧用戶側(cè)的高性價(jià)比需求和網(wǎng)絡(luò)側(cè)的低阻塞率需求。
