技术领域
本发明涉及非连续接收模式（DRX )处理技术， 特别是一种 DRX处理 方法、 用户设备及基站。 背景技术
在长期演进（ LTE, Long Term Evolution )系统中， 为了用户设备 ( UE, User Equipment )省电， 定义了 DRX模式。 在 DRX模式下， UE不必每个子 帧都进行 PDCCH盲检测， 为关闭接收电路提供了条件。 DRX模式下， 激活 状态 （Active Time )和非激活状态 （Non-active Time ) 交替存在， UE离开 Active Time就进入 Non-active Time。在 DRX模式下， UE仅仅需要在 Active Time期间进行 PDCCH盲检测。 Active Time是根据演进基站（ eNodeB ) 配 置的 DRX参数以及业务调度的情况来确定的。 Active Time按周期启动， 当 没有业务传输时进入 Non-active Time期间，并需要等到下一个周期才能重新 进入 Active Time期间。
^口图 1所示， DRX模式下， 无业务时， Active time和 non-active time交 替出现， Active time按周期启动。 UE仅仅在 Active time期间接收基站下发 的数据； 在 non-active time期间不接收基站下发的数据， 不检测 PDCCH。
AB两点之间是 Active time期间，是基站配置的持续定时器（ onduration timer ) 运行的时间， 其中 A箭头表示开始或重启持续定时器， B箭头表示持续定时 器超时。 图中的 "偏移"表示 Onduration Timer启动时刻， 在一个 DRX周期 中的偏移量。
如图 2所示， DRX模式下，有业务时， 当 UE检测到基站调度的 PDCCH 时，会进一步延长 active time时间，具体为非激活态定时器（ inactivity timer ) 运行时间， 该 inactivity timer取值可变， 最短为 1毫秒。
具体地， 当 UE进入 non-active time期间， B箭头后， 有数据要发送时， 可以通过发送 SR ( Scheduling Request, 进程请求）向基站申请上行授权， 用 以发送上行数据。 D箭头时， UE向基站发送 SR, C箭头、 E箭头接收到基 站的上行授权 ( PDCCH with DCIO ), E箭头时刻为 active time并延迟到 F箭 头（ inactivity timer停止），此后 UE进入 non-active time期间直到下一个 DRX 周期， 此间不接收基站下发的数据。
如图 3所示，相关技术中 DRX模式下的切换流程，主要包括以下步骤： 步骤 301 : UE和基站建立 RRC连接；
步骤 302: 基站通过 RRC重配过程配置业务以及 DRX模式参数并启动 DRX模式；
步骤 303: UE根据 DRX模式参数和基站的业务调度情况， 确定进入和 退出 Active time;
步骤 304： 当 UE进入 non-active time期间， UE移动进入切换区域， 向 基站发送测量报告；
或者， UE 移动进入切换区域， 向基站发送测量报告后， 很快进入 Non-active time。
步骤 305: 由于 UE在 non-active time期间不接收基站的数据，基站将在 下一次 active time启动后， 才发送 RRC重配并携带切换配置参数；
步骤 306: UE在再次进入 active time后， 接收到 RRC重配， 完成切换 处理过程， 并向目标基站发送 RRC重配完成响应。
如图 4的相关技术中 DRX模式下的新业务发起流程， 主要包括以下步 骤：
步骤 401 : UE和基站建立 RRC连接；
步骤 402: 基站通过 RRC重配过程配置业务以及 DRX模式参数并启动 DRX模式；
步骤 403: UE根据 DRX模式参数和基站的业务调度情况， 确定进入和 退出 Active time;
步骤 404: 当 UE进入 non-active time期间 , UE有新业务发起时 , 向核 心网发起请求； （核心网处理该请求后， 通过和基站交互信息， 并激发基站对 UE的 RRC重配） 步骤 405: 由于 UE在 non-active time期间不接收基站的数据，基站将在 下一次 active time启动后， 才发送 RRC重配并携带新业务相关参数；
步骤 406: UE在再次进入 active time后， 接收到 RRC重配， 完成相关 重配过程， 并向基站发送 RRC重配完成响应。
相关技术中， DRX周期最长可以达到 2.56秒。 在某些情形下， 可能出 现 UE在 2秒多的时间里都不去检测 PDCCH, 也就不会接收 eNodeB下发的 业务数据和信令。 当用户有交互式业务需求、 有紧急业务交互或者 UE正在 移动切换到新的小区时，若 UE处于 Non-active Time期间而不去检测 PDCCH, 就不能接收网侧下发的业务信令和数据， 将会导致用户体验下降、 甚至切换 掉线。

实施例 2
本发明实施例 2的非连续接收模式（DRX )处理方法， 如图 6所示， 包 括步骤 601-步骤 604:

步骤 701 : 用户设备（UE )在非连续接收模式（DRX )下， 检测是否发 生需要保持或进入激活状态的事件； 所述事件包括但不限于当前处于切换区域或需要发起紧急呼叫。

上述指示信息向基站指明： UE在此后 L时长的时间里处于 Active Time 期间， 而不会进入 Non-active Time期间。
基站收到 UE发送的上述指示信息时， 认为 UE在此后的 L时长的时间 里处于 Active Time期间， 即认为 UE会连续接收基站下发的数据。
步骤 703: UE设置退出普通的非连续接收模式（DRX ) 的标志， 退出 DRX模式且保持或进入激活状态， 接收基站发送的数据；
所述 UE发送所述指示信息时处于激活状态或非激活状态， 发送所述指 示信息后持续保持激活状态或由非激活状态转为激活状态。

超出所述时长后， 恢复普通的非连续接收模式（DRX )下的状态调整方 式。
可替换地， 实施例 1中也可在发送指示信息后， 设置退出普通的非连续 接收模式（DRX ) 的标志， 或达到约定时长后， 消除所述标志， 再根据普通 的非连续接收模式（DRX )进行状态调整。
本发明针对相关技术中的上述问题， 给出了 UE退出非连续接收状态的 方法， 使得在非连续接收模式下用户能够及时进行业务交互以及提升 UE切 换的可靠性。
以下结合具体实例对本发明方法实施例 2、 3进行详细说明：
如图 8 , 在本发明实施例中， 对比图 2, UE在 D时刻发送 SR, 在 E时 刻收到基站的上行授权， 在 G时刻利用该上行授权向基站发送指示信息， 指 示信息 UE在此后的一段时间里退出 non-active time (保持在 active time ),并 启动定时器 B。 在 H时刻， 定时器 B超时， UE重新进入 non-active time, 直 到下一个 DRX周期的 active time启动时刻。
如图 9,在本发明实施例中，和图 8的区别是，图 8的 SR发送在 non-active time期间发起，而图 9的 SR发送在 active time期间发起。进一步的对比是， 图 8表明了 UE在有业务需求时从 non-active time期间退出并保持在 active time期间一段时间的场景； 而图 9表明了 UE在有业务需求时维持在 active time期间一段时间， 即不按普通 DRX模式来进入 non-active time期间。
可见，通过本发明实施例的方法， 可以退出 non-active time并保持 active time—段时间， 并且可以知会到基站， 使得 UE和基站对 UE状态的理解达 成一致。 进一步的， 本发明实施例从 non-active time时间里退出并恢复对基 站数据的连续接收。 而相关技术不具备这种机制和方法。
如图 10, 釆用本发明实施例的方法后， DRX模式下的切换流程， 主要 包括以下步骤 1001 -步骤 1010:
步骤 1001 : UE和基站建立 RRC连接；
步骤 1002:基站通过 RRC重配过程配置业务以及 DRX模式参数并启动 DRX模式；
步骤 1003: UE根据 DRX模式参数和基站的业务调度情况，确定进入和 退出 Active time;
步骤 1004: 当 UE进入 non-active time期间， UE移动进入切换区域； UE根据测量情况来决定是否退出 non-active time, 在退出时设置标志， UE 向基站发送指示信息； 步骤 1005: UE向基站发送测量报告；
步骤 1006: UE设置定时器 B;
步骤 1007: 基站接收到 UE的指示信息，知道 UE保持在 active time (即 可以连续接收基站的数据）； 基站发送 RRC重配及切换；
步骤 1008: UE接收到 RRC重配切换命令后， 进行切换过程处理； 步骤 1009： UE发送 RRC重配完成消息给目标基站；
步骤 1010: 定时器 B超时， UE清除上述标志， 恢复普通 DRX模式处 理， 即根据 DRX参数和业务调度情况来确定 active time进入和退出。
相关技术中， 如图 3所示， UE发送测量报告到基站发送 RRC重配（切 换）之间， 有虚线的一段时长， 根据 DRX周期的取值， 最大可能达到 2秒 多。而在连续接收状态时，测量报告和 RRC重配之间的时间间隔在几十个毫 秒之内。 延迟 2秒有可能造成切换过程失败， 引发重建， 并需要更长的时间 来恢复连接。 与相关技术相比， 本发明实施例中当 UE发送测量报告后可以 及时接收到基站下发的 RRC重配切换命令，并及时完成切换过程，可避免切 换过程的掉线。
如图 11 ,釆用本发明实施例的方法后， DRX模式下的新业务发起流程， 主要包括以下步骤 1101-步骤 1109:
步骤 1101： UE和基站建立 RRC连接；
步骤 1102:基站通过 RRC重配过程配置业务以及 DRX模式参数并启动 DRX模式；
步骤 1103: UE根据 DRX模式参数和基站的业务调度情况，确定进入和 退出 Active time;
步骤 1104: 当 UE进入 non-active time期间 , UE有新业务发起； UE根 据业务特性和 QOS要求情况来决定是否退出 non-active time, 在退出时设置 标志， UE向基站发送指示信息；
步骤 1105: UE通过基站向核心网发起新业务请求；
步骤 1106: UE设置定时器 B; 步骤 1107: 基站接收到 UE的指示信息， 知道 UE保持在 active time (即 可以连续接收基站的数据）； 基站发送 RRC重配；
步骤 1108: UE接收到 RRC重配后， 进行重配过程处理， 发送 RRC重 配完成消息给基站；
步骤 1109: 定时器 B超时， UE清除上述标志， 恢复普通 DRX模式处 理， 即根据 DRX参数和业务调度情况来确定 active time进入和退出。
相关技术中，如图 4所示， UE发起新业务请求到基站发送 RRC重配（新 业务相关配置）之间， 有虚线的一段时长， 根据 DRX周期的取值， 最大可 能达到 2秒多。 较多的延迟可能引发高层重传， 进一步的加大延迟， 造成用 户体验下降。
与相关技术相比， 本发明实施例中当 UE发起新业务请求后可以及时接 收到基站下发的 RRC重配命令， 并及时完成重配过程， 可避免因 DRX模式 而影响用户体验。
为实现上述方法， 本发明实施例提供了一种用户设备（UE ) , 如图 12 所示， 该用户设备包括检测模块 1201、 发送模块 1202、 状态调整模块 1203 和数据接收模块 1204, 其中：
