Description

小区切换处理方法、装置、终端及基站 技术领域
本发明涉及通信领域，具体而言，涉及一种小区切换处理方法、装置、终端及基站。
背景技术
宽带码分多址接入(Wideband Code Division Multiple Access，简称为WCDMA)移动终端经过R99、R5(高速下行分组接入(High Speed Downlink Packet Access，简称为HSDPA))、R6(高速上行分组接入(High Speed Uplink Packet Access，简称为HSUPA))、R7(高速分组接入增强(High Speed Packet Access Plus，简称为HSPA+))、R8(双小区高速分组接入增强(Dual Cell-High Speed Packet Access Plus，简称为DC-HSPA+))等等一系列无线资源控制(Radio Resource Control，简称为RRC)协议版本的演进发展，数据传输能力越来越强大。R99终端具有最大下行384Kb/s，最大上行64Kb/s的数据传输速率；R5(HSDPA)终端具有最大下行14Mb/s，最大上行384Kb/s的数据传输速率；R6(HSUPA)终端具有最大下行14Mb/s，最大上行5.76Mb/s的数据传输速率；R7(HSPA+)终端具有最大下行21Mb/s，最大上行11.5Mb/s的数据传输速率；R8(DC-HSPA+)终端具有最大下行42Mb/s，最大上行11.5Mb/s的数据传输速率。目前，R99、R5、R6、R7、R8等等终端都在市场上存在，主要的终端类型是R6、R7、R8。而运营商的网络在不断地演进和部署过程中，也存在不同RRC版本的小区。WCDMA移动终端在数据传输的过程中从一个小区移动到另外一个小区时会发生切换过程。切换的过程主要包括以下几个步骤：首先是切换前的准备过程。网络通过“测量控制”信令给终端下发需要测量的目标小区列表及测量量、报告门限、报告规则等参数。然后，在终端的移动过程中进行测量过程。终端根据网络下发的这些参数对目标小区进行测量，当测量到的某个小区的信号强度达到报告门限时，终端发送“测量报告”信令给网络。最后，网络根据“测量报告”中上报的目标切换小区进行切换判决，执行切换，将终端切换到目标小区。
由于网络的部署比较复杂，同一区域可能存在多种类型小区的信号，比如R99小区、HSDPA小区、HSUPA小区、HSPA+小区、DC-HSPA小区等等。目前终端在数据传输过程中使用的传统切换处理方法没有考虑到不同小区类型的问题。比如终端本来处于HSPA+小区，测量到了若干个信号强度相近的不同类型的小区，但由于R99小区 的信号比HSPA+小区信号稍好，首先达到门限，终端报告了R99小区，网络把终端切换到了R99小区。这将导致终端数据传输速率大幅度下降。
因此，在相关技术中在进行小区间的切换处理时，存在终端数据传输速率下降的问题。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种小区切换处理方法，图1是根据本发明实施例的小区切换处理方法一的流程图，如图1所示，该流程包括如下步骤：
步骤S102，接收基站下发的测量控制消息，其中，该测量控制消息中包括用于指示终端进行测量的目标小区，目标小区的小区类型，目标小区类型对应的测量偏置门限值，以及目标小区的测量信号强度或信号质量达到测量偏置门限值后对测量信号强度或信号质量进行偏置的测量偏置值；
步骤S104，依据对目标小区进行测量获取的测量信号强度或信号质量，测量偏置门限值，以及测量偏置值对目标小区的测量信号强度或信号质量进行偏置；
步骤S106，依据偏置后的测量信号强度或信号质量选择终端切换的目标小区。
通过上述步骤，通过依据对测量信号进行偏置处理，依据偏置后的测量信号强度或信号质量选择终端切换的目标小区，解决了相关技术中在进行小区间的切换处理时，存在终端数据传输速率下降的问题，进而达到了使得终端可以切换到优先级更高的小区，从而获得传输速率更高的数据传输性能的效果。
在依据对目标小区进行测量获取的测量信号强度或信号质量，测量偏置门限值，以及测量偏置值对目标小区的测量信号强度或信号质量进行偏置时，可以采用多种处理方式，例如，可以先对小区类型划分优先级；在终端支持的小区类型的最高优先级和终端当前服务小区的小区类型的优先级中较小优先级低于目标小区的小区类型的优先级，且终端支持的小区类型的最高优先级高于终端当前服务小区的小区类型的优先级的情况下，为目标小区的测量信号强度或信号质量增加正的测量偏置值；和/或，又例如，在终端支持的小区类型的最高优先级和终端当前服务小区的小区类型的优先级中较小优先级高于目标小区的小区类型的优先级的情况下，为目标小区的测量信号强度或信号质量增加负的测量偏置值。
需要说明的是，在测量信号为接收信号码功率RSCP的情况下，测量偏置门限值为-115dBm到-25dBm，对应的测量偏置值为1到10dBm；在测量信号为信噪比Ec/No的情况下，测量偏置门限值为-24dB到0dB，对应的测量偏置值为1到5dB。
图2是根据本发明实施例的小区切换处理方法二的流程图，如图2所示，该流程包括如下步骤：
步骤S202，向终端发送测量控制消息，其中，测量控制消息中包括用于指示终端进行测量的目标小区，目标小区的小区类型，目标小区类型对应的测量偏置门限值，以及目标小区的测量信号强度或信号质量达到测量偏置门限值后对测量信号强度或信号质量进行偏置的测量偏置值；

通过上述步骤，向终端发送测量控制消息，从而使得终端通过依据对测量信号进行偏置处理，依据偏置后的测量信号选择终端切换的目标小区，解决了相关技术中在进行小区间的切换处理时，存在终端数据传输速率下降的问题，进而达到了使得终端可以切换到优先级更高的小区，从而获得传输速率更高的数据传输性能的效果。
优选地，在接收到终端依据测量控制消息对小区进行测量后获得的测量报告之后，还可以将终端切换到测量报告中选择切换的目标小区。

针对相关技术中的上述问题，在本实施例中，提供了一种增强WCDMA移动终端在数据传输时切换性能的方法，通过该方法，能够使终端在移动过程中切换到较传统切换方式更高数据传输速率的小区中去，使终端获得更高的数据传输速率，提高用户的使用体验。该WCDMA小区之间的切换方法可以采用以下处理方式：
终端确认处于数据传输过程中；在“测量控制(Measurement Control)”信令中增加目标小区类型及新的控制参数；新的测量报告算法。下面分别说明。
终端确认处于数据传输过程中的方法。例如，终端首先需要确认是否处于“PMM CONNECTED”状态，即是否已和网络建立了PS Signaling Connection，如是，则可认为已处于数据传输过程中。需要说明的是，本实施例可能只适用于数据传输过程中的切换，不适用于有语音通话或其他电路域过程中的切换，所以还需确认当前是否有语音通话或其他电路域过程，终端只需要确认是否处于“MM CONNECTION ACTIVE”状态，即RRC层已完成“安全模式控制(security mode control)过程”或MM层收到“CM SERVICE ACCEPT”消息。终端确认处于“PMM CONNECTED”及不处于“MM CONNECTION ACTIVE”状态后，则可发起本实施例所描述的测量过程。
表1-3是根据本发明实施例的“测量控制”信令中增加的目标小区类型及新的控制参数的示意表，如表1-3所示，在“测量控制(Measurement Control)”信令中增加目标小区类型及新的控制参数。在“测量控制(Measurement Control)”信令中增加目标小区类型参数“Cell type for data transmission”，增加的小区类型包括：R99小区、HSDPA小区、HSUPA小区、HSPA+小区、DC-HSPA小区。增加用于数据传输时使用本方法的测量偏置门限参数“Measurement threshold for data transmission”，取值范围及单位根据测量量的不同而不同，当测量量为CPICH RSCP时，取值从-115dBm到-25dBm，当测量量为CPICH Ec/No时，取值从-24到0dB。增加用于数据传输时使用本方法的测量偏置值“Measurement offset for data transmission”，取值范围及单位根据测量量的不同而不同，当测量量为CPICH RSCP时，取值从1到10dB，当测量量为CPICH Ec/No时，取值从1到5dB。在信令中增加的参数形式见表1-表3。

表3
新的测量报告算法。首先，终端对不同类型传输类型优先级进行排序：优先级从低到高依次是：“R99”(优先级为1)<“HSDPA”(优先级为2)<“HSUPA”(优先级为3)<“HSPA+”(优先级为4)<“DC-HSPA”(优先级为5)。终端在测量过程中根据所在当前小区的类型及终端所支持的最高优先级传输类型(R99、HSDPA、HSUPA、HSPA+或DC-HSPA)来对测量到的不同类型目标小区的信号强度(RSCP)或信号质量(Ec/No)(根据测量控制中的参数决定)增加偏置值。规则如下：
1.只对信号强度或信号质量需高于测量偏置门限参数“Measurement threshold for data transmission”的测量目标小区使用此新算法；
2.当终端支持的最大类型优先级和当前服务小区类型优先级中的最小优先级低于测量到的小区类型的优先级，且终端支持的最大类型优先级高于当前服务小区类型优先级时，给测量到的小区信号强度或信号质量增加正的偏置值；
3.当终端支持的最大类型优先级和当前服务小区类型优先级中的最小优先级高于测量到的小区类型优先级时，给测量到的小区信号强度或信号质量增加负的偏置值；
4.其他情况，不给测量到的小区信号强度或信号质量增加任何偏置值。
通过在相关技术中WCDMA网络的终端测量和切换机制上增加了终端在测量过程中对网络类型优先级的判断及相应的处理，使得终端可以上报网络类型优先级更高的小区作为切换目标小区，从而使网络将终端切换到网络类型优先级更高的小区，使终端获得速率更高的数据传输性能。
下面结合附图对本发明优选实施方式进行说明。
终端在当前服务小区进行数据传输，终端支持的最高优先级传输类型是“HSUPA”，当前服务小区的类型是“HSDPA”。终端已确认处于“PMM CONNECTED”状态及不处于“MM CONNECTION ACTIVE”状态。之后根据网络下发的“测量控制(Measurement Control)”信令进行测量过程。
在本优选实例中，网络在“测量控制(Measurement Control)”信令中下发的测量目标小区有2个，第一个是“临小区1”，其小区类型为“R99”；第二个是“临小区2”，其小区类型为“HSUPA”。测量量为信号强度RSCP。测量偏置门限参数“Measurement threshold for data transmission”的值为“-90dBm”。测量偏置值“Measurement offset for data transmission”的值为3dB。
当测量到的目标小区信号强度高于-90dBm时，开始使用本发明描述的方法进行测量及报告。图9是根据本发明实施例的切换过程实例的示意图，如图9所示。
终端支持的最高优先级传输类型是“HSUPA”，即优先级为3；
当前服务小区的类型是“HSDPA”，即优先级为2；
临小区1的小区类型为“R99”，即优先级为1；
临小区2的小区类型为“HSUPA”，即优先级为3。
计算终端支持的最大类型优先级和当前服务小区类型优先级中的最小优先级为2，低于临小区2的小区类型优先级3，高于临小区1的小区类型优先级1。所以，对测量到的临小区1的信号强度RSCP值+3dB，对测量到的临小区2的信号强度RSCP值-3dB，形成实际使用的信号强度值。从图上可以看到，服务小区信号强度随时间不断降低，测量目标小区“临小区1”和“临小区2”的信号强度随时间不断增高。如果不采用本发明，只是用传统的测量及测量报告方法，测量目标小区的信号质量没有偏置，临小区1的信号高于临小区2的信号，终端会在时间点B上报测量报告，将切换目标小区“临小区1”报告给网络，网络会将终端切换到“临小区1”，由于“临小区1”的小区类型为“R99”，终端的数据传输速率会降低。采用本发明后，测量目标小区的信号质量发生偏置，“临小区1”的信号低于“临小区2”的信号，终端会在时间点A上报测量报告，将切换目标小区“临小区2”报告给网络，网络会将终端切换到“临小区2”，由于“临小区2”的小区类型为“HSUPA”，终端的数据传输速率不会降低。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性如上所述，本发明实施例提供的小区切换处理方法、装置、终端及基站。解决了相关技术中在进行小区间的切换处理时，存在终端数据传输速率下降的问题，进而达到了使得终端可以切换到优先级更高的小区，从而获得传输速率更高的数据传输性能的效果。
