摘要

切换控制是保证用户在蜂窝基础设施中移动业务不间断运行的重要手段之一。在之前的工作中，我们说明了使用当前3GPP指定的切换控制算法向跨小区边界的用户提供MBMS(多媒体广播多播服务)服务的连续性会导致容量或QoS效率低下，并提出了一种新的基于MEHO(移动评估切换)的MBMS切换控制算法来补偿它们。该算法虽然在容量和QoS方面是有效的，但在对有效的MBMS切换执行至关重要的某些参数的估计方式方面存在一些局限性。在本文中，我们使用一种不同的方法(网络评估切换(NEHO))，我们改进了以前的工作并提出了一种不同的方法，该方法在实现相同容量和QoS效率的同时消除了所有前任的缺陷。

A NEHO based MBMS Handover Control approach

Handover Control is one of the essential means to guarantee the continuity of mobile services to a user traveling in a cellular infrastructure, without interruption. In previous work we illustrated that using the current 3GPP specified handover control algorithm to provide continuity of MBMS (Multimedia Broadcast Multicast Service) services to a user crossing cell boundaries results either in capacity or QoS inefficiencies and proposed a new MEHO (Mobile Evaluated Handover) based MBMS handover control algorithm that compensated for them. This algorithm, although effective in terms of capacity and QoS, has some limitations concerning the way certain parameters vital for the efficient MBMS handover execution are estimated. In this paper, using a different approach (Network Evaluated Handover (NEHO)), we enhance previous work and propose a different method, that eliminates all of its predecessorpsilas deficiencies while achieving the same capacity and QoS efficiencies.
