Description
电能优化方法及*** 技术领域
本发明涉及电能优化技术, 尤其涉及一种电能优化方法及***。 背景技术
机器到机器(M2M, Machine to Machine )通信是指机器之间建立连接 的所有通信技术和手段。 M2M通信理念在上个世纪九十年代就出现了, 但 仅停留在理论阶段。 2000 年以后, 随着移动通信技术的发展, 以移动通信 技术实现机器设备的联网成为可能。 2002 年左右 M2M 业务就在市场上出 现, 并在随后的几年迅速发展, 成为了众多通信设备商和电信运营商的关 注焦点。 目前全球的机器数量比人的数量要多很多, 因此可以预见到 M2M 技术的良好的市场前景。
对 M2M通信应用场景研究表明在移动网络上提供 M2M通信具有潜在 的市场前景。但 M2M业务对***提出了很多新的要求, 为了增强移动网络 在这方面的竟争力, 有必要对现有的移动网络进行优化, 以更有效地支持 M2M通信。
现有的移动通信网络主要针对人与人的通信进行设计, 而对机器与机 器,人与机器的通信则优化不足。此外,运营商如何能够以低成本提供 M2M 通信服务, 也是 M2M通信部署能否成功的关键。
基于以上情况,有必要研究移动网络支持 M2M通信的解决方案,解决 方案应当最大限度重用现有网络,以降低大量 M2M通信对网络造成的影响 以及运营维护的复杂度。
目前电信市场竟争曰趋激烈, 资费不断下降, 运营商利润空间不断减 小, 以人为基础的通信市场正趋于饱和, M2M对运营商来说是全新的发展
机遇。
为了有效地利用移动网络资源, 第三代合作伙伴计划 (3GPP, 3rd Generation Partnership Project )提出了机器类型通信 ( MTC , Machine Type Communication ), 即机器对机器( Machine to Machine )、机器对人 ( Machine to Man )进行通讯的业务,其业务范围远远超出了以往人对人( H2H, Human to Human )之间的通讯, MTC在接入控制、计费、安全性、服务质量( QoS, Quality of Service )、业务模式等方面与现在的 H2H通讯模式有很大的区别。
图 1为 3GPP演进分组业务***(EPS, Evolved Packet System ) 架构 示意图, 如图 1所示, EPS包括了无线接入网 (如 E-UTRAN, UTRAN, GERAN )和核心网,如在演进分组业务核心网( EPC, Evolved Packet Core ) 中设有移动性管理实体 ( MME , Mobility Management Entity ) , Serving Gateway, PDN Gateway等网元, 在 GPRS核心网中包括服务 GPRS支持节 点 ( SGSN, Serving GPRS Support Node )等网元; 在 E-UTRAN中包括演 进的节点 B ( eNB, evolved Node B )。
对于电池供电的 MTC UE,需要采取措施以降低 UE功耗,对于有电源 供电的 MTC UE, 同样需要降低 UE功耗, 以实现绿色节能的目标。 目前, 智能手机逐渐普及, 同时出现了大量的应用业务运行在智能手机上, 这些 应用业务可能造成智能手机电池的功耗增加, 寿命缩短, 因此智能手机的 节电也是一个必须解决的关键问题。

为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
图 2为本发明实施例一的电能优化方法的流程图, 如图 2所示, 本示 例的电能优化方法包括以下步骤:
步骤 201, UE请求或网络侧指示进入长休眠周期。
所述 UE请求是指 UE向网络侧发送请求信息, 或者用户操作 UE向网 络侧发送请求信息; 上述请求信息包括以下一种或多种: UE标识, 长休眠 周期使能标识。 其中, UE标识可以是以下任意一种: 国际移动用户识别码 ( IMSI, International Mobile Subscriber Identification Number )、 移动台识另 'J 号码( MSISDN, Mobile Subscriber International ISDN/PSTN Number )、 UE 外部标识; 长休眠周期使能标识用于指示 UE进入长休眠周期。其中长休眠 周期的长度由网络侧配置并通过 RRC信令事先发送给 UE。 如图 3所示, 为本发明实施例的长、 短周期示意图, 长 DRX周期的时长一般是短 DRX 周期的整数倍,如果连续多个短 DRX周期( DRX短周期定时器, DRX Short Cycle Timer ) 内没有分组数据收发, 则 UE进入长 DRX周期。 所述长休眠 周期为长 DRX周期, 包括活动时间和休眠时间, 其中活动时间用于监听寻 呼信道和 /或广播信道, 在活动时间内, 所述 UE可以收发分组业务, 其中 休眠时间用于 UE停止收发分组业务, 关闭大部分的收发电路。 所述 UE可 以处于连接态 RRC— Connected或空闲态 RRC— Idle状态,对于连接态 DRX, 所述网络侧保存 UE上下文信息, 对于空闲态 DRX, 所述网络侧删除 UE 上下文信息。
需要指出的是, 本发明实施例以 DRX为例说明, 并不排除非连续发送
DTX的使用, 事实上, 本发明的实施例同样适用于 DTX, 本发明的休眠周 期也可以是网络设置的节能定时器。
所述网络侧是指以下一种或多种: 基站、 MME/SGSN; 所述网络侧指 示是指: 网络侧向 UE发送消息, 用于通知 UE进入长休眠周期状态; 所述 消息包括以下一种或多种: UE标识、 长休眠周期标识。 其中 UE标识可以 是单个 UE标识,或者一类 UE标识,如低优先级 UE标识(低优先级级别) 等。
所述 UE包括 MTC设备和智能终端, 其中 MTC UE是指具有 MTC功 能的 UE, 智能终端包括: 智能手机、 平版电脑、 上网卡、 上网本等; 对于 MTC UE, 如果没有显示指示, 缺省进入长休眠周期。
所述 UE和网络侧根据应用的延时要求选择进入长休眠周期,例如应用 的延时需求大于长休眠周期引起的延时。如果 UE上运行多个不同延时需求 的业务应用, 则 UE根据最小延时需求的应用选择休眠周期。
需要指出的是: 缺省的, 网络侧接受 UE请求, 或 UE接受网络侧的指 示; 如果网络侧或 UE拒绝进入长休眠周期, 例如应用的延时不满足, 或有 上 /下行分组业务到达, 则网络侧向 UE发送拒绝响应, 或者 UE向网络侧 发送拒绝响应; 如果没有拒绝响应, 则 UE进入长休眠周期。
步骤 202, 判断休眠时间内是否有分组业务到达, 如果是, 则执行步骤 203 , 否则执行步骤 204。
所述判断是指 UE返回活动模式后进行判断;所述休眠时间是指长休眠 周期中的休眠时间; 所述分组业务包括上行和下行分组业务, 即 UE发送和 接收的分组业务。
步骤 203, UE 进入活动模式收发分组业务, 分组业务收发结束, UE 进入短休眠周期。
所述 UE包括连接态和空闲态, 对于连接态 UE, 直接返回活动模式,
对于空闲态 UE, 先进行连接请求与网络侧建立连接;
如果所述分组业务为下行分组业务, 即需要 UE接收的分组业务, 则需 要等到休眠时间结束, 所述 UE监听寻呼信道 (或监听广播信道 )并接收分 组业务;
如果所述分组业务为上行分组业务, 即需要 UE发送的分组业务, 则 UE立即从休眠模式返回活动模式并发送分组业务, 如果所述 UE处于空闲 态, 则所述 UE发起随机接入过程与网络侧建立连接并发送分组业务; 需要指出的是, 处于休眠模式的 UE可以发起位置更新过程, 如 UE移 动过程中, 进入新的位置区域。
步骤 204, UE重新进入长休眠周期或更长休眠周期。
所述 UE在当前休眠周期结束后, 再次进入长休眠周期; 这里, 所述更 长休眠周期为长休眠周期的整倍数, 由网络侧通过 AS/NAS信令事先通知 所述 UE.

步骤 402, 网络侧判断是否接受 UE请求, 如果是, 则执行步骤 403, 否则执行步骤 404。
所述网络侧根据应用的延时和自身需要判断是否接受 UE请求,例如网 络侧应用的延时大于长休眠周期的休眠时间, 和 /或在长休眠周期的休眠时 间有下行数据发送到 UE, 则网络侧拒绝 UE请求。
步骤 403, UE进入长休眠周期。
所述长休眠周期 T包括: 活动时间 Ta和休眠时间 Ts, 即 T=Ta+Ts; 其 中在活动时间 Ta内, UE可以发送或接收数据分组业务, 如果在 Ta内没有 分组业务到达, 则 UE在 Ta到期直接进入休眠态; 如果在 Ta内有分组业务 到达, 则 UE在收发分组业务之后启动定时器 Tl,如果在 T1时间内没有分 组业务到达, 则当 T1到期 UE直接进入休眠时间, 如果在 T1时间内有分 组业务到达, 则 UE收发分组业务后重新启动定时器 Tl。 如图 5所示, 图 中示出了 Ta, Ts, T1之间的关系示意。
所述 UE在休眠态 (休眠时间内 ) 时关闭大部分发送电路和接收电路, 但是 UE没有关机或者从网络去附着( detach ), 此时网络侧保存 UE的上下 文信息, 直到 UE更新位置或发送服务请求为止。

所述分组业务到达是指在长休眠周期的休眠时间内到达;
所述分组业务可以是上行或下行分组业务, 所述上行分组业务是指 UE 发送的分组业务, 所述下行分组业务是指 UE接收的分组业务。
步骤 406, UE进入活动模式收发分组业务。
如果是上行分组业务,则 UE退出休眠态进入活动态发送分组业务; 如 果是下行分组业务,则 UE等到当前休眠时间结束然后进入活动态监听寻呼 信道(或监听广播信道)并接收下行分组业务。
步骤 407, 分组业务收发结束, UE进入短休眠周期。
所述分组业务收发结束后, 所述 UE启动定时器 Tl,如果在 T1时间内 没有分组业务到达, 则当 T1到期 UE直接进入短休眠时间, 如果在 T1时 间内有分组业务到达, 则 UE收发分组业务后重新启动定时器 Tl, 直到 T1 到期 UE进入短休眠时间。
所述 UE进入短休眠周期的同时, 启动定时器 Τ2, 当 Τ2到期, UE进 入长休眠周期。
步骤 408, 当前长休眠周期结束, UE重新进入长休眠周期, 流程结束。 所述长休眠周期结束, UE进入下一个长休眠周期; 所述 UE处于连接 态, 网络侧可以释放 RRC连接并在基站删除 UE上下文信息, UE进入空 闲态;
如果网络侧配置了超过长休眠周期的更长休眠周期,则 UE可以进入更 长的休眠周期。
