Description

一种异系统测量的方法、相关装置及系统 技术领域
本发明涉及通信技术领域，具体涉及一种异系统测量的方法、相关装置及系统。
背景技术
全球移动通讯系统(Global System of Mobile Communication，GSM)或者宽带码分多址(Wideband Code Division Multiple Access，WCDMA)等第二代(Second Generation，2G)或者第三代网络(Third Generation，3G)网络已经基本实现了全面覆盖。
随着长期演进(Long Term Evolution，LTE)网络技术的发展，这些LTE网络已覆盖到一些城区和话务热点地区，这样在目前的通信网络中，LTE网络与2G/3G网络并存。由于LTE网络正在建设阶段，有的LTE网络可能只支持数据业务，不支持语音业务，当处于LTE网络中的用户设备(User Equipment,UE)发起语音业务时，UE需要先回退到具有电路交换(Circuit Switched，CS)域的2G/3G网络，在具有CS域的2G/3G网络进行语音业务，上述从LTE网络的CS域切换至2G/3G网络的CS域的技术，称为电路域回落(Circuit Switched Fallback，CSFB)技术；而有的LTE网络可能支持语音业务，则UE可以使用基于LTE的语音(Voice over LTE，VoLTE)业务，然而，由于LTE网络并没有实现全面覆盖，正在使用VoLTE的UE如果处于LTE网络和2G/3G网络的边界区域或即将进入只覆盖了2G/3G网络的区域，通常需要将VoLTE切换到2G/3G网络的CS域，来避免语音中断。
在上述执行LTE网络到2G/3G网络的CS域切换之前，通常需要在LTE网络对2G/3G网络的信号质量进行测量，即执行异系统测量，以便LTE网络选取信号质量符合要求的2G/3G小区。目前，进行异系统测量通常是通过间隙(gap,GAP)模式来进行的。采用GAP模式进行异系统测量时，通常是在 40ms/80ms的周期内进行6ms的测量，虽然这种测量方式可以避免对业务产生影响，但是对于存在多个2G/3G邻区尤其是多个2G邻区时将会耗费较长的时间才能完成异系统测量，使得呼叫切换准备时间过长，导致在CSFB呼叫时间过程中发生语音会话中断或者进行VoLTE业务时发生语音会话中断。

具体实施方式
本发明实施例提供一种异系统测量的方法、相关装置及系统，能够加速异系统测量，减少测量时间，从而减少呼叫切换准备时间，避免语音会话中断。本发明实施例还提供了相应的设备及系统。
本发明实施例中的第一、第二、第三、第四、第五等仅用于区分不同的指示信息、消息或其他对象，不代表顺序关系。
为更清楚地描述本发明的实施例，首先对本发明实施例相关的知识做一些介绍。
关于C-DRX：在通信网络中，基于包的数据流通常是突发性的，在没有数据传输的时候，可以通过关闭UE的接收电路来降低功耗，从而提升电池使 用时间。这就是连续态下的不连续接收(Connected-Discontinuous Reception，C-DRX)的由来。C-DRX的基本机制是为处于RRC_CONNECTED态的UE配置C-DRX周期(Connected-Discontinuous Reception Cycle)。C-DRX cycle由“On Duration”和“Opportunity for DRX”组成：在“On Duration”的时间内(即在激活期内)，UE被允许监听并接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)的数据；在“Opportunity for DRX”时间内(即在休眠期内)，UE不接收物理下行控制信道的数据以节省功耗。
关于VoLTE：现有的2G/3G的核心网由PS域和CS域组成，其中，语音和其它CS补充业务由CS域支撑；LTE核心网不包括CS域，只有PS域，因此，被称为演进分组系统(Evolved Packet System，EPS)。LTE网络为了提供语音业务必须包括IP多媒体子系统(IP Multimedia Subsystem，IMS)，IMS为会话控制层，因此，LTE/EPS系统中语音业务称为VoLTE业务或IMS基于IP的语音(voice over IP，VoIP)业务。
异系统测量是指位于某个网络制式的UE对其它网络制式的信号质量进行测量，例如位于LTE网络的UE对2G/3G网络的信号质量进行测量，异系统测量通常发生在网络切换之前。在现有技术中，UE进行异系统测量时，通常采用GAP模式，即在每个40ms/80ms的周期内采用6ms进行测量，可以避免对业务产生影响。然而，对于多个2G/3G邻区尤其是多个2G邻区，需要较长的测量时间，采用现有技术的测量方式，可能会耗费多个40ms/80ms的周期才能完成异系统测量，使得呼叫切换准备时间过长，导致在CSFB呼叫时间过程中发生语音会话中断或者UE进行VoLTE业务时发生语音会话中断。
本发明实施例提出了一种异系统测量的方法、相关装置及系统，能够在演进基站(evolved NodeB，eNodeB)发送给位于LTE网络的UE的测量控制消息中包含C-DRX参数和测量控制参数，所述C-DRX参数和所述测量控制参数可以指示UE在C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量，例如，C-DRX周期可以由所述C-DRX参数确定，所述C-DRX参数可以按照如下方式配置：在整个C-DRX周期内，激活期的持续时间在大于零的情况下尽可能短，而休眠期的持续时间在小于C-DRX周期的时长的情况下尽可能长， 使得UE可以较长时间停留在C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量。采用上述方式，有效加速了位于LTE网络的UE对2G/3G网络的信号质量的测量，缩短了测量时间，解决了现有技术中采用GAP模式进行异系统测量时导致的呼叫切换准备时间过长或语音会话中断的问题。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
参阅图1，图1为本发明实施例提供的异系统测量的方法，所述方法包括：
S101：eNodeB确定所述UE支持从所述LTE网络到所述2G或3G网络的CS域的切换。
所述eNodeB可以首先判断所述UE是否支持从所述LTE网络到所述2G或3G网络的CS域的切换，如果所述UE支持从所述LTE网络到所述2G或3G网络的CS域的切换，则需要在切换之前对2G或3G网络的信号质量进行测量。
例如，所述eNodeB在对位于LTE网络的UE进行电路域回落CSFB的过程中，在将所述UE从所述LTE网络移动到2G或3G网络的CS域之前，可以判断所述UE是否支持从所述LTE网络到所述2G或3G网络的CS域的切换；或者，eNodeB为所述UE提供VoLTE业务过程中，在将所述UE从所述LTE网络移动到2G或3G网络的CS域之前，可以判断所述UE是否支持从所述LTE网络到所述2G或3G网络的CS域的切换。
S102：所述eNodeB发送测量控制消息给所述UE，所述测量控制消息包含第一C-DRX参数和测量配置参数，所述第一C-DRX参数和所述测量配置参数用于指示所述UE在第一C-DRX周期的休眠期内对所述2G或3G网络的信号质量进行测量。
所述测量控制消息可以是无线资源控制协议连接重配置(RRC Connection Reconfiguration)消息。由于所述测量控制消息包含的第一C-DRX参数和测量配置参数，所述UE可以根据所述第一C-DRX参数和所示测量配置参数的指示，在所述第一C-DRX周期的休眠期内持续对所述2G或3G网络的信号质量进行测量。
具体地，所述测量配置参数可以包含对所述2G或3G网络的信号质量进行 测量所需的相关信息，例如所述测量配置参数可以包含所述UE需要测量的对象、小区列表、报告方式、测量标识或事件参数等；所述第一C-DRX周期可以由所述第一C-DRX参数确定，所述第一C-DRX周期可以包括休眠期和激活期，在第一C-DRX周期的休眠期内，所述UE不接收物理下行控制信道的数据，在第一C-DRX周期的激活期内，所述UE监听并接收物理下行控制信道的数据。当所述测量控制消息包含了所述测量配置参数和所述第一C-DRX参数时，所述测量控制消息可以用于指示所述UE在第一C-DRX周期的休眠期内对所述2G或3G网络的信号质量进行测量，即所述测量配置参数和所述第一C-DRX参数用于指示所述UE在第一C-DRX周期的休眠期内对所述2G或3G网络的信号质量进行测量。通过上述方式，所述UE可以在整个所述第一C-DRX周期的休眠期内，都可以持续对所述2G或3G网络的信号质量进行测量，避免在40ms/80ms的周期内只能进行6ms的测量，即避免采用GAP模式进行测量，加速了测量过程，缩短了测量时间，从而有效减少了呼叫切换准备时间，避免在CSFB呼叫时间过程中发生语音会话中断或者进行VoLTE时语音会话中断。
可选地，所述第一C-DRX参数和所述测量配置参数还可以用于指示所述UE在所述第一C-DRX周期的激活期内采用GAP模式对所述2G或3G网络的信号质量进行测量。
进一步，所述第一C-DRX周期可以由第一C-DRX参数确定。因此通过调整第一C-DRX参数，可以调整UE持续进行异系统测量的时间。具体说来，所述第一C-DRX参数可以按照如下方式配置：在整个第一C-DRX周期内，使得激活期的时长(即激活期的持续时间)在大于零的情况下尽可能短，而休眠期的时长(即休眠期的持续时间)在小于第一C-DRX周期的时长情况下尽可能长，从而UE可以较长时间停留在第一C-DRX周期的休眠期，在第一C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量，大大加速了异系统测量。
例如，所述第一C-DRX周期的休眠期的时长T1s可以不小于51ms；可选地，T1s可以大于等于80ms或者大于等于100ms，从而所述UE可以在一个休眠期内就完成异系统测量；又例如，所述第一C-DRX周期的休眠期的时长T1s与所述 第一C-DRX周期的时长T1d的比值大于0.6(即T1s/T1d>60％)；可选地，T1s/T1d大于0.8或者大于0.9，从而保证休眠期的时长在小于周期的时长的情况下尽可能的长，使得UE可以有效利用C-DRX周期进行测量，加速异系统测量。
可选地，在步骤S102之前，所述方法还可以包括步骤S100：
S100：所述eNodeB向所述UE发送第二C-DRX参数。
所述eNodeB可能为了降低功耗等目的，向所述UE发送第二C-DRX参数，所述C-DRX参数用于为所述UE配置第二C-DRX周期，所述第二C-DRX周期可以包括休眠期和激活器，在所述第二C-DRX周期的休眠期内所述UE不接收物理下行控制信道的数据以节省功耗。所述第二C-DRX周期可以由所述第二C-DRX参数确定。
可选地，由于为了不影响UE进行正常业务，发送的第二C-DRX参数可能会被配置为：使得第二C-DRX周期的休眠期的时长比较短，或者使得第二C-DRX周期的休眠期的时长与所述第二C-DRX周期的时长的比值比较小，例如，可能将第二C-DRX周期的时长设置为160ms，休眠期的时长设置为50ms。因此，所述第一C-DRX参数可以这样设置：使得在相同时间内，UE停留在第一C-DRX周期的休眠期的时间比停留在第二C-DRX周期的休眠期的时间更长，从而增加UE能够持续进行异系统测量的时间，减少异系统测量耗费的时间，加快异系统测量。例如，可以使得第一C-DRX周期的休眠期的时长大于第二C-DRX周期的休眠期的时长；或者，使得所述第一C-DRX周期的休眠期的时长与所述第一C-DRX周期的时长的比值大于第二C-DRX周期的休眠期的时长与所述第二C-DRX周期的时长的比值。
进一步，所述方法还可以包括：
S103：所述eNodeB接收所述UE返回的测量报告。
所述测量报告可以包括UE对所述2G或3G网络的信号质量进行测量所得的测量结果。
可选地，所述eNodeB可以根据所述测量报告，确定执行所述LTE网络到所述2G或3G网络的CS域切换，执行步骤S104。
S104：所述eNodeB在接收到所述测量报告之后，向移动管理实体(Mobile  Managenment Entity，MME)发送切换要求(Handover Required)消息，以触发所述LTE网络到所述2G或3G网络的CS域切换过程。
然而，如果上述切换过程失败，所述UE仍然处于C-DXR状态，可能较长时间停留在第一C-DRX周期的休眠期，影响正常业务的进行，为了解决这个问题，所述方法还可以包括：
S105：所述eNodeB确定所述切换过程失败。
S106：所述eNodeB发送所述第二C-DRX参数给所述UE，或者发送请求消息给所述UE，所述请求消息用于指示所述UE关闭所述UE的C-DRX功能。
在所述确定所述切换过程失败时，所述eNodeB可以通过向所述UE发送所述第二C-DRX参数，使得UE恢复到进行异系统测量之前的C-DRX状态，以降低功耗的同时兼顾所述UE进行正常业务；或者，所述eNodeB可以通过向所述UE发送指示所述UE关闭所述UE的C-DRX功能的请求消息，关闭所述UE的C-DRX功能，避免对业务的影响。
此外，若S103中所述eNodeB接收所述UE返回的测量报告，根据所述测量报告确定不执行所述LTE网络到所述2G或3G网络的CS域切换，则所述eNodeB可以发送所述第二C-DRX参数给所述UE，或者发送请求消息给所述UE，所述请求消息用于指示所述UE关闭所述UE的C-DRX功能。
本实施例中eNodeB与UE的交互，以及eNodeB的上述处理步骤的详细描述，可以参考以下其它方法实施例。
本发明实施例提供了一种异系统测量的方法，所述方法包括：
S201：位于LTE网络的UE接收eNodeB发送的测量控制消息，所述测量控制消息携带第一C-DRX参数和测量配置参数，所述第一C-DRX参数和所述测量配置参数用于指示所述UE在第一C-DRX周期的休眠期内对2G或3G网络的信号质量进行测量。
例如，在演进基站eNodeB对位于LTE网络的UE进行CSFB的过程中，或者在所述eNodeB为所述UE提供VoLTE业务过程中，所述UE接收eNodeB发送的测量控制消息。所述测量控制消息可以是无线资源控制协议连接重配置(RRC  Connection Reconfiguration)消息。
可选地，步骤S201之前，所述UE可以接收所述eNodeB发送的第二C-DRX参数，所述第二C-DRX参数用于所述UE确定第二C-DRX周期，即所述UE可以被配置第二C-DRX周期，所述UE可以在所述第二C-DRX周期的休眠期内不接收物理下行控制信道的数据，以降低功耗，提升UE的电池使用时间。
所述第一C-DRX参数的具体信息和所述测量配置参数的具体信息，可以参考其它方法实施例，本发明实施例不再赘述。
S202：所述UE在所述第一C-DRX周期的休眠期内对所述2G或3G网络的信号质量进行测量。
对2G或3G网络的信号质量进行测量可以是对2G或3G网络的参考信号接收功率(Reference Singnal Received Power,RSRP)或者参考信号接收质量(Reference Singnal Received Quanity,RSRQ)进行测量。
由于所述测量控制消息中包含了所述第一C-DRX参数和所述测量控制参数，因此所述UE可以根据所述第一C-DRX参数和所述测量配置参数的指示，或者根据所述测量控制消息的指示，在所述第一C-DRX周期的休眠期内持续对所述2G或3G网络的信号质量进行测量，避免采用GAP模式进行测量，加速了测量过程，缩短了测量时间。进一步，所述第一C-DRX周期可以由所述第一C-DRX参数确定，所述第一C-DRX参数可以按照如下方式配置：在整个第一C-DRX周期内，使得激活期的时长(即激活期的持续时间)在大于零的情况下尽可能短，而休眠期的时长(即休眠期的持续时间)在小于第一C-DRX周期的时长的情况下尽可能长，从而使得UE较长时间停留在第一C-DRX周期的休眠期，在整个第一C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量，大大加速了异系统测量。
可选地，因为UE发送上行数据时，可能会迫使所述UE退出CDRX周期的休眠期，因此，所述UE在接收到所述测量控制消息之后，可以停止或暂停发送上行数据。例如，所述测量控制消息中可以携带用于指示所述UE停止或暂停发送上行数据的指示信息，所述UE可以在接收到所述测量控制消息之后，根据所述指示信息停止或暂停发送上行数据；又例如，所述UE可以在接收到 所述测量控制消息之后，自动停止或暂停发送上行数据。
S203：所述UE根据对所述2G或3G网络的信号质量进行测量所得的测量结果，生成测量报告，所述UE向所述eNodeB发送所述测量报告。
可选地，所述UE在向所述eNodeB发送所述测量报告之后，或者完成对2G或3G网络的信号质量的测量之后，可以恢复发送上行数据。
通常在完成异系统测量之后，可以进入切换流程，所述方法还可以包括：
S204：所述UE接收所述eNodeB发送的切换命令，所述切换命令用于指示所述UE从所述LTE网络切换到2G或3G网络的CS域，所述切换命令中包含所述2G或3G网络为所述UE从所述LTE网络切换到所述2G或3G网络的CS域分配的CS域无线资源的信息；所述UE根据所述切换命令，从所述LTE网络切换到所述2G或3G网络的CS域。
然而，如果从所述LTE网络切换到所述2G或3G网络的CS域失败，或者所述eNodeB确定不执行所述LTE网络到所述2G或3G网络的CS域切换，则所述eNodeB可能不会发送的切换命令，所述方法还可以包括：
S204a’：所述UE接收所述eNodeB发送的所述第二C-DRX参数，所述UE根据所述第二C-DRX参数恢复到进行异系统测量之前的C-DRX状态。
可选地，所述方法还可以是：
S204b’：所述UE接收所述eNodeB发送的请求消息，所述请求消息用于指示所述UE关闭所述UE的C-DRX功能。
通过步骤S204a’或步骤S204b’，可以减少不需要进行异系统测量时(例如切换失败后)，对业务的影响，提高用户体验。
本实施例中eNodeB与UE的交互，以及UE的上述处理步骤的详细描述，可以参考其它方法实施例。
本发明实施例提供了一种异系统测量的方法，可以应用于eNodeB在对位于LTE网络的UE进行电路域回落CSFB的过程中，所述UE需要进行异系统测量的场景。所述方法可以包括：
S300：eNodeB向位于LTE网络的UE的发送第二C-DRX参数。
当UE附着到LTE网络之后，所述eNodeB可以向所述UE发送第二C-DRX参数，以使所述UE节省功耗。所述第二C-DRX参数用于为所述UE配置第二C-DRX周期。
S301：所述UE根据所述第二C-DRX参数，在第二C-DRX周期的激活期内监听并接收PDCCH的数据，在所述第二C-DRX周期的休眠期内不接收PDCCH的数据，所述第二C-DRX周期由所述第二C-DRX参数确定。
所述UE在接收到所述第二C-DRX参数时，可以停留在所述第二C-DRX周期的休眠期或者激活期。
S302：所述UE向MME发送请求消息，所述请求消息用于请求CSFB。
S303：所述MME向所述eNodeB发送通知消息，所述通知消息用于指示所述eNodeB为CSFB将所述UE从所述LTE网络移动到2G或3G网络的电路交换CS域。
S304：所述eNodeB确定所述UE支持从所述LTE网络到所述2G或3G网络的CS域的切换。
具体说来，所述eNodeB可以根据UE上报的特性组指示(Feature Group Indicator，FGI)能力，判断所述UE是否支持从所述LTE网络到所述2G或3G网络的CS域的切换。如果确定所述UE支持从所述LTE网络到所述2G或3G网络的CS域的切换，则指示所述UE进行异系统测量，以便进行切换。
关于如何判断所述UE是否支持从所述LTE网络到所述2G或3G网络的CS域的切换可以有多种实现方方式，本发明实施例在此不作限定。
S305：所述eNodeB发送无线资源控制协议连接重配置消息给所述UE，所述无线资源控制协议连接重配置消息携带第一C-DRX参数和测量参数，所述第一C-DRX参数和所述测量配置参数用于指示所述UE在第一C-DRX周期的休眠期内对2G或3G网络的信号质量进行测量。
所述第一C-DRX参数和所述测量配置参数用于指示所述UE在第一C-DRX周期的休眠期内对2G或3G网络的信号质量进行测量；即所述无线资源控制协议连接重配置消息用于指示所述UE在第一C-DRX周期内对2G或3G网络的信号质量进行测量。
所述测量参数可以包含对所述2G或3G网络的信号质量进行测量所需的相关信息，所述UE可以根据所述测量配置参数对自身进行测量配置。例如所述测量配置参数可以包含所述UE需要测量的对象、小区列表、报告方式、测量标识或事件参数等信息，进一步，可以参考3GPP标准。
所述第一C-DRX参数可以按照如下方式配置：使得在相同时间内，UE停留在第一C-DRX周期的休眠期的时间比停留在第二C-DRX周期的休眠期的时间更长，从而增加UE能够持续进行异系统测量的时间，减少异系统测量耗费的时间，加快异系统测量。例如，可以使所述第一C-DRX周期的休眠期的时长T1s大于第二C-DRX周期的休眠期的时长T2s，或者使得所述第一C-DRX周期的休眠期的时长与所述第一C-DRX周期的时长的比值大于第二C-DRX周期的休眠期的时长与所述第二C-DRX周期的时长的比值。可选地，由于所述第二C-DRX周期的休眠期通常设置的比较小，因此，所述第一C-DRX周期的休眠期的时长T1s可以不小于100ms，或者所述第一C-DRX周期的休眠期的时长T1s与所述第一C-DRX周期的激活期的时长T1d的比值可以大于80％(即T1s/T1d>80％)。
例如，C-DRX参数可以包括：长周期的长度(long drx cycle)、DRX持续时间定时器(on duration timer)和DRX非激活定时器(drx inactivity timer)；如果所述第二C-DRX参数设置为LONGDRXCYCLE＝PSF160，ONDURATIONTIMER＝PSF8，DRXINACTIVITYTIMER＝PSF80，表示第二C-DRX周期的时长为160ms,所述UE如果在8ms+80ms内没有接收到PDCCH的数据，才可能进入第二C-DRX周期的休眠期，休眠期的时长为160ms-8ms-80ms，即72ms。则所述第一C-DRX参数可以设置为：long drx cycle＝PSF160，on duration timer＝PSF2，drx inactivity timer＝PSF2；表示第二C-DRX周期的时长为160ms，所述UE如果在2ms+2ms内没有接收到PDCCH的数据，则可能进入第一C-DRX周期的休眠期，休眠期的时长为160ms-2ms-2ms，即156ms，从而所述UE可以在156ms内持续进行异系统测量，可能在一个休眠期内就完成异系统测量。
S306：所述UE根据所述测量配置参数进行配置，并在所述配置完成之后， 向所述eNodeB发送测量控制确认消息。
所述测量控制确认消息可以为无线资源控制协议连接重配置完成(RRC Connection Reconfiguration Complete)消息。
S307：所述UE在所述第一C-DRX周期的休眠期内对所述2G或3G网络的信号质量进行测量。
在第一C-DRX周期的休眠期内，所述UE不接收物理下行控制信道的数据，可以直接持续地对2G或3G网络的信号质量进行测量，例如对2G或3G网络的RSRP或RSRQ进行测量。
可选地，所述UE还可以在所述第一C-DRX周期的激活期内采用GAP模式进行异系统测量。
S308：所述UE根据测量结果，生成测量报告，并发送给所述eNodeB。
当UE完成测量后，所述UE会依照所述测量配置参数进行判断，当设定条件满足时，UE将测量结果填入测量报告，发送给所述eNodeB。所述测量报告中可以包括：测量标识(ID)和测量结果(例如RSRP和RSRQ的测量值)。
S309：所述eNodeB根据所述测量报告，判断所述UE是否需要进行切换，当所述eNodeB确定有必要切换时，确定一个目标小区，执行S310。
S310：所述eNodeB向移动管理实体MME发送切换要求消息，以触发所述LTE网络到所述2G或3G网络的CS域切换过程。
所述切换要求消息可以用于请求所述MME为了CSFB将所述UE从所述LTE网络切换到所述2G或3G网络的CS域。所述切换要求消息可以为从所述LTE网络到所述2G或3G网络的所述CS域切换要求消息，例如：SRVCC HO Required(Single Radio Voice Call Continuity Handover Required)消息。
S311：执行所述LTE网络到所述2G或3G网络的CS域切换过程。
所述MME在接收到所述切换要求消息之后，可以通过所述2G或3G网络的移动交换中心(Mobile Services Switching Centre，MSC)向所述2G或3G网络的基站(Base Station，BS)请求为所述UE切换到所述2G或3G网络的CS域分配CS域资源，所述MME在获取到所述基站分配的CS域无线资源的信息之后，可以向eNodeB发送切换要求响应消息，所述切换要求响应消息包含CS域无线 资源的信息，所述CS域无线资源的信息用于所述UE从所述LTE网络切换到所述2G或3G网络的CS域。从而所述eNodeB可以接收所述切换要求响应消息，向所述UE发送切换命令，所述切换命令用于指示所述UE从所述LTE网络切换到所述2G或3G网络的CS域，所述切换命令包含所述CS域无线资源的信息。所述UE可以根据所述切换命令，从所述LTE网络切换到所述2G或3G网络的CS域。
进一步，如果上述切换过程失败，则所述UE仍然处于第一C-DXR周期的休眠期或第一C-DXR周期的激活期。然而，通常为了加速异系统测量，所述第一C-DXR周期的休眠期的时长将设置得比较长。在切换失败之后如果UE仍然停留在较长的休眠期将影响正常业务。因此，为了解决这个问题，所述方法还可以包括：
S312：所述eNodeB确定所述切换过程失败。
如果所述eNodeB接收所述MME发送的切换要求响应消息，所述切换要求响应消息携带切换失败指示，所述切换失败指示用于指示所述切换过程失败，则确定所述切换过程失败；或者，所述eNodeB在预设时间内未接收到所述MME发送的切换要求响应消息，则所述eNodeB确定所述切换过程失败。
S313：所述eNodeB发送所述第二C-DRX参数给所述UE，以使所述UE恢复到进行异系统测量之前的C-DRX状态。
所述UE可以根据所述第二C-DRX参数，在第二C-DRX周期的激活期内监听并接收PDCCH的数据，在所述第二C-DRX周期的休眠期内不接收PDCCH的数据。
本发明实施例提供了一种异系统测量的方法，eNodeB在对位于LTE网络的UE进行电路域回落CSFB的过程中，在将所述UE从所述LTE网络移动到2G或3G网络的CS域之前，向所述UE发送测量控制消息，所述测量控制消息包含第一C-DRX参数和测量配置参数，所述UE可以根据所述第一C-DRX参数和所示测量配置参数的指示，在所述第一C-DRX周期的休眠期内持续对所述2G或3G网络的信号质量进行测量，避免在40ms/80ms的周期内只能进行6ms的测量，有效加速了位于LTE网络的UE对2G/3G网络的信号质量的测量，缩短了测量时间，解决了现有技术中采用GAP模式进行异系统测量时导致的呼叫切换准备时 间过长或语音会话中断的问题。
进一步，由于所述第一C-DRX周期的休眠期的时长由第一C-DRX参数决定，所述第一C-DRX参数可以按照如下方式配置：在整个第一C-DRX周期内，使得激活期的时长(即激活期的持续时间)在大于零的情况下尽可能短，而休眠期的时长(即休眠期的持续时间)在小于第一C-DRX周期的时长情况下尽可能长，从而UE可以较长时间停留在第一C-DRX周期的休眠期，在第一C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量，大大加速了异系统测量。
本发明实施例提供的异系统测量的方法也可以应用于eNodeB为位于LTE网络的UE提供VoLTE业务过程中，需要将VoLTE切换到2G/3G网络的CS域，在该切换之前进行异系统测量的场景。此时，将步骤S302和S303替换为S302’-S303’即可。
S302’：附着于LTE网络的UE正在进行VoLTE业务。
S303’：eNodeB确定需要对所述UE执行从所述LTE网络到所述2G或3G网络的CS域切换。
例如，所述eNodeB可以根据所述UE发送的LTE网络质量的测量报告，确定所述LTE网络无法继续为UE提供服务，即确定需要对所述UE执行从所述LTE网络到所述2G或3G网络的CS域切换。
与上述方法实施例对应，本发明实施例提出了一种演进基站eNodeB，如图4所示，所述演进基站40包括确定单元401和交互单元402；
所述确定单元401，用于确定所述UE支持从所述LTE网络到2G或3G网络的CS域的切换；例如，在所述eNodeB对位于长期演进LTE网络的用户设备UE进行电路域回落CSFB的过程中，或者为所述UE提供基于LTE网络的语音VoLTE业务过程中，确定所述UE支持从所述LTE网络到2G或3G网络的电路交换CS域的切换。

可选地，所述第一C-DRX参数和所述测量配置参数还可以用于指示所述UE在所述第一C-DRX周期的激活期内采用GAP模式对所述2G或3G网络的信号质量进行测量。
可选地，所述第一C-DRX周期可以由所述第一C-DRX参数确定，所述第一C-DRX周期的休眠期的时长不小于51ms；或者，所述第一C-DRX周期由所述第一C-DRX参数确定，所述第一C-DRX周期的休眠期的时长与所述第一C-DRX周期的时长的比值大于0.6。
可选地，为了降低所示UE的功耗等目的，所述交互单元402在发送所述测量控制消息给所述UE之前，可以发送第二C-DRX参数发送给所述UE，所述第二C-DRX参数用于为所述UE配置第二C-DRX周期，以使所述UE在第二C-DRX周期的激活期内监听并接收PDCCH的数据，在所述第二C-DRX周期的休眠期内不接收PDCCH的数据，从而节约所述UE的功耗。
可选地，所述第二C-DRX周期可以由所述第二C-DRX参数确定，则所述第一C-DRX参数可以这样设置：使得第一C-DRX周期的休眠期的时长大于第二C-DRX周期的休眠期的时长；或者，使得所述第一C-DRX周期的休眠期的时长与所述第一C-DRX周期的时长的比值大于第二C-DRX周期的休眠期的时长与所述第二C-DRX周期的时长的比值，从而增加UE能够持续进行异系统测量的时间，减少异系统测量耗费的时间，加快异系统测量。
可选地，所述交互单元402还可以接收所述UE返回的测量报告，根据所述测量报告确定不执行所述LTE网络到所述2G或3G网络的CS域切换，发送所述第二C-DRX参数给所述UE；或者，

所述交互单元402还可以接收所述UE返回的测量报告，根据所述测量报告 确定不执行所述LTE网络到所述2G或3G网络的CS域切换，发送请求消息给所述UE，所述请求消息用于指示所述UE关闭所述UE的C-DRX功能；或者，
所述交互单元402还可以接收所述UE返回的测量报告，向移动管理实体MME发送切换要求消息，以触发所述LTE网络到所述2G或3G网络的CS域切换过程，确定所述切换过程失败，则发送所述请求消息给所述UE。
可选地，因为UE发送上行数据时，可能会迫使所述UE退出第一CDRX周期的休眠期，影响异系统测量，因此所述测量控制消息中可以携带用于指示所述UE停止或暂停发送上行数据的指示信息。
本发明实施例提供了一种演进基站，所述演进基站的交互单元402可以在所述演进基站的确定单元401确定UE支持从所述LTE网络到2G或3G网络的CS域的切换时，向所述UE发送测量控制消息，所述测量控制消息包含第一C-DRX参数和测量配置参数，以使所述UE可以根据所述第一C-DRX参数和所示测量配置参数的指示，在所述第一C-DRX周期的休眠期内持续对所述2G或3G网络的信号质量进行测量，避免在40ms/80ms的周期内只能进行6ms的测量，有效加速了位于LTE网络的UE对2G/3G网络的信号质量的测量，缩短了测量时间，解决了现有技术中采用GAP模式进行异系统测量时导致的呼叫切换准备时间过长或语音会话中断的问题。
进一步，由于所述第一C-DRX周期的休眠期的时长由第一C-DRX参数决定，所述第一C-DRX参数可以按照如下方式配置：在整个第一C-DRX周期内，使得激活期的时长(即激活期的持续时间)在大于零的情况下尽可能短，而休眠期的时长(即休眠期的持续时间)在小于第一C-DRX周期的时长情况下尽可能长，从而UE可以较长时间停留在第一C-DRX周期的休眠期，在第一C-DRX周期的休眠期内持续对2G/3G网络的信号质量进行测量，大大加速了异系统测量。

可选地，所述第二C-DRX周期由所述第二C-DRX参数确定。则，所述第一C-DRX参数可以这样设置：使得所述第一C-DRX周期的休眠期的时长大于第二C-DRX周期的休眠期的时长；或者，使得所述第一C-DRX周期的休眠期的时长与所述第一C-DRX周期的时长的比值大于第二C-DRX周期的休眠期的时长与所述第二C-DRX周期的时长的比值；
可选地，所述处理单元502还可以用于根据对所述2G或3G网络的信号质量进行测量所得的测量结果，生成测量报告；所述交互单元501还可以用于向所述eNodeB发送所述测量报告。
