Description

小区重选方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种小区重选方法、装置及系统。
背景技术
LTE(Long Term Evolution，长期演进)是由3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)组织制定的UMTS(Universal Mobile Telecommunications System，通用移动通信系统)技术标准的长期演进。LTE系统引入了OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)和MIMO(Multi-Input&Multi-Output，多输入多输出)等关键传输技术，显著增加了频谱效率和数据传输速率。LTE第一阶段技术，于2008年底完成标准化并在2009年开始进行商用网络部署(对应3GPP R8/R9版本)。为满足未来无线通信市场的更高需求和更多应用，同时还保持对LTE较好的后向兼容性，3GPP在2010年启动了LTE的演进版本LTE-Advanced(LTE-A)的研究(对应3GPP R10及后续版本)。LTE-A采用了载波聚合(Carrier Aggregation)、上/下行多天线增强(Enhanced UL/DL MIMO)、多点协作传输(Coordinated Multi-point Tx&Rx)、中继(Relay)、异构网干扰协调增强(Enhanced Inter-cell Interference Coordination forHeterogeneous Network)等关键技术，能大大提高无线通信系统的峰值数据速率、峰值频谱效率、小区平均谱效率以及小区边界用户性能，同时也能提高整个网络的组网效率。而且随着技术的演进，不断有新的技术被LTE所采纳，例如在LTE-R12中，将支持包括TDD与FDD间的载波聚合(TDD-FDD CA)、小小区双链接(small cell dual connectivity)等新的技术，进一步提高无线通信系统的峰值速率、频谱效率以及整个网络的运行效率。
由于商用网络部署与LTE标准技术演进的平行推进，目前市场上广泛存在着采用不同版本的基站与采用不同协议版本的终端。考虑到不同协议版本功能上的差异，基于不同协议版本的设备在功能上也会有较大差异(即使是基于相同的协议版本，考虑到制造成本、目标市场等因素，不同的基站、终端在支持的功能上也可能有较大区别)，而终端在某基站下能够发挥的最大能力取决与终端与基站能力的交集。例如基于3GPPR11版本技术的基站相对于基于3GPP R9版本技术的基站而言，采用R11协议版本的基站能够支持载波聚合，8×8下行MIMO/4×4上行MIMO等功能，可以提供更高的传输速率及效率。但是，这些功能必须要配合支持这些功能的R11终端才能有效的发挥。由于根据目前的协议描述，UE在进行小区选择、重选时并不会考虑终端、基站 间的能力匹配问题，基站无法为不同能力的UE配置不同的小区选择重选参数，终端也无法通过系统消息获知基站的具体能力，因此也无法做到根据设备能力有针对性的驻留。如果大量R9的终端驻留在了R11基站所辖小区内，或者大量R11终端驻留在了R9基站所辖小区内，终端和基站由于版本、能力的不匹配会导致设备能力无法有效发挥从而造成传输效率、速率的下降，对用户体验有较大负面影响。
针对相关技术中由于终端和基站的版本及能力等不匹配而导致设备能力无法有效发挥进而造成传输效率及速率下降的问题，目前尚未提出有效的解决方案。
