Description

一种睡眠模式下业务指示消息发送方法及装置 技术领域 本发明涉及移动通信领域，尤其涉及一种睡眠模式下基站（BS, Base Station ) 向移动台 （MSS, Mobile Subscriber Station ) 下发业务指示消息 的方法及装置。
背景技术
在移动通信系统中， 待机时间的长短对于终端的移动自由度有着非 常大的影响， 延长待机时间可以通过两种方式来实现， 一种方式是采用 高效的电池；另一种方式是尽可能的减少移动终端的无谓功率消耗。 IEEE ( Institute of Electrical and Electronic Engineers, 电子电气工程师协会) 802.16e 是一个正在制定过程中的移动宽带无线接入系统标准， IEEE802.16e的 D8草案中定义的移动终端睡眠模式就属于后一种方式。 所谓睡眠模式是移动终端在与基站预先协商的时间区间内， 空口暂时中 断与基站联系的过程。 实现睡眠模式过程可以减少移动终端在上行链路 和下行链路上的传输请求， 从而减少 MSS的功率消耗。
MSS可以主动向 Serving BS ( Serving Base Station, 服务基站 )发送 睡眠请求消息 MOB一 SLP—REQ请求进入睡眠模式， 然后 Serving BS发送 睡眠响应消息 MOB一 SLP—RSP来同意或拒绝 MSS进入睡眠模式。也可以 由 BS主动发送睡眠响应消息 MOB一 SLP— RSP来要求 MSS进入睡眠模式， MSS收到后， 一般情况下根据睡眠响应消息 MOB—SLP—RSP中携带的参 数进入睡眠模式。
目前前述协议规定， MSS和 BS进行商议， 将当前的服务流根据其 QoS ( Quality of Service, 服务廣量）要求和特性分为 3类睡眠组， 对不 同类别的睡眠组分别采取不同的睡眠策略， 每一类可以包含多个睡眠组， 同一类别的睡眠组与睡眠组之间采用相同的睡眠策略和不同的睡眠参 数， 睡眠参数根据每一组中具体包括的业务特点选择。 每一睡眠组可以 包含多个服务流， 每个服务流代表 MSS和 BS之间的业务连接， 可以是 上行或下行，通过一个 16比特的连接标识符（CID, Connection Identifier ) 来标识。 每一个睡眠组的睡眠状态分为激活状态和非激活状态。 在激活 状态下， 本睡眠组的睡眠状态机正常进行； 在非激活状态下， 本睡眠组 的睡眠状态机复位， 停止进行。 MSS可以存在多个睡眠组， 与所有睡眠 组的侦听窗口不重叠的时间区域为不可用区间 （ Unavailability interval ), 与 Unavailability interval 不重叠的其它时间段为可用区间 （ Availability interval )D MSS只有在不可用区间才是真正处于睡眠状态， 此时该 MSS 的所有睡眠组都在睡眠窗口状态。 在可用区间内， 可以有某些睡眠组处 于睡眠窗口状态， 其它睡眠组处于侦听状态， MSS 实际上在清醒状态， 只不过各个睡眠组的睡眠状态机处于不同的状态下。
第一类睡眠组定义为 Power—Saving— Class__Type=l , —般应用于实时 性要求不高的业务。 它的睡眠策略是采用固定的侦听窗口长度和可变的 睡眠窗口长度， 侦听窗口和睡眠窗口交替， 当前睡眠窗口长度依次为上 一次睡眠窗口长度的 2倍， 直到达到规定的最大值， 然后保持不变和侦 听窗口交替进行。 直到 MSS或 BS发起睡眠状态改变请求， 设置睡眠状 态为非激活状态， 此睡眠组的睡眠状态机才停止。
第二类睡眠组定义为 Power—Saving— Ciass—Type-2, —般应用于周期 性发送数据的业务。 它的睡眠策略是釆用固定的侦听窗口长度和固定的 睡眠窗口长度， 然后睡眠窗口和侦听窗口交替出现， 直到 MSS或 BS发 起睡眠状态改变请求， 设置睡眠状态为非激活状态， 此睡眠组的睡眠状 态机才停止。
第三类睡眠组定义为 Power— Saving— Class— Type=3 , 一般应用于多播 业务。 它采用的睡眠策略是只设置一次睡眠窗口， 在睡眠窗口超时后此 睡眠组的睡眠状态为非激活状态， 睡眠状态机停止， 直到 MSS或 BS通 过消息交互重新激活此组的睡眠状态机。
对于第一类睡眠组而言， BS可以在这类睡眠组的侦听窗口期间发送 业务指示消息 MOB—TRF— IND， 用来指示是否有针对这个睡眠组的服务 流的业务数据。 MSS中第一类睡眠组中各个睡眠组在 Availability interval 区间如果接收到的业务指示消息中指示有针对本睡眠组的业务数据， 则 该睡眠组的睡眠状态变为非激活状态， 睡眠状态机复位； 如果没有， 则 这个睡眠组的睡眠状态仍为激活状态， 睡眠状态机照常进行， 在侦听窗 口结束以后进入睡眠状态； 如果有针对这个睡眠组中业务流的业务数据， 则这个睡眠组的睡眠状态转为非激活状态， 睡眠状态机复位。
图 1是一个 MSS中存在两个睡眠组的睡眠状态示意图， 第一个睡眠 组 110属于第一类睡眠组， BS分配固定长度的侦听窗口 111和依次为上 一次睡眠窗口 2倍的睡眠窗口 112;第二个睡眠组 120属于第二类睡眠组， BS分配固定长度的侦听窗口 121和睡眠窗口 122。 斜线区域 130显示了 两类睡眠组的综合效果， 其中： 有阴影的斜线区间 131 为 Availability intervals, 无阴影的斜线区间 132为 Unavailability intervals„
目前 802.16e/D8草案中关于业务指示消息的设计， 进行如下的规定：
1、 业务指示消息只针对第一类睡眠组设置。
2、 BS通过发送业务指示消息来停止第一类睡眠组的激活状态。
3 、 如果 MSS在睡眠请求消 息 MOB— SLP— REQ中设置 了 TRP—IND— Required标志位， 则 MS S如果在 Availability interval期间如果没 有接收到业务指示消息 MOB— TRFJND, 则这个睡眠组将在 Availablity interval结束后自动变为非激活状态。
4、 对于第一类睡眠组， BS可以为每个睡眠組分配一个 SLPID (睡眠 组标识） ， 用来标识各个 MSS上不同的睡眠组（每个睡眠组对应一个唯 一的 SLPID ) 。 BS可以在业务指示消息 MOB— TRFJND中通过 SLHD来指 示各个睡眠组是否有业务下发。
本模式下，基于 SLPID进行业务指示，通过两个映射表， SLPID Group Indication bit_map (睡眠组指示比特映射 )和 Traffic Indication bit_map (睡 眠组业务指示比特映射） ， 来进行相关睡眠组的业务指示。
SLPID Group Indication bit— map如图 2所示。其中 1024个 SLPID分为 32 个业务指示单元，每个业务指示单元包括 32个 SLPID，每个业务指示单元 对应于 SLPID Group Indication bit— map中的 1个比特。
其中每个比特的意义：
0: 该比特对应的业务指示单元内的所有 SLPID对应的睡眠组都没有 业务指示。 1： 该比特对应的业务指示单元中至少有一个 SLPID对应的睡眠组有 业务指示。
II
Traffic Indication bit— map如图 3所示。其中 Traffic Indaication bit— map 包含若干个业务指示单元， 这些业务指示单元依次对应 SLPID Group Indication bit— map中比特位为 1的比特所对应的业务指示单元。 每个业务 指示单元为 32bit，每一 bit^j"应于该业务指示单元中的一个 SLPID,如果 bit = 0表示该 SLPID对应的睡眠组没有业务， bit = 1表示该 SLPID对应的睡眠 组有业务存在。
5、 如果 MSS内的所有睡眠組都有业务指示或都没有业务指示， 则可 以采用 Short Basic CID (缩短的基本连接标识）方式来对 MSS的各个睡眠 组进行统一指示， 有业务指示， 则列出该 MSS的 Short Basic CID, 反之则 不列出。
现有的上述方案， 本领域技术人员通常称为映射指示法和缩短的基 本连接标识指示法。
目前协议规定业务指示消息 MOB— TRF— IND的格式如表 1所示：

} 目前 802.16e/D8 草案中关于 BS 向 MSS 发送业务指示消息 MOB_TRP_IND的方案存在以下不足：
1、在利用 SLPID进行睡眠业务指示时采用的是映射方法， 在有些情 况下， 例如只有很少个数的睡眠组有业务数据， 如果采用映射的方式要 浪费很多带宽资源。
2、该方案设计不够灵活，只能采用 SLPID映射的方式进行业务指示， 或者只能采用 Short Basic CID的方式进行指示。 上述两种方案只能是择 一的关系， 这无形中增加了网络负担。

} 如图 4所示， 是本发明睡眠模式下业务消息发送方法的流程示意图， 从图 4中可见， 本发明主要包括以下步骤：
Sl、 BS向 MSS发送业务指示消息。
BS向 MSS发送业务指示消息， 所述的业务指示消息中设置标志位， 用以标识睡眠组的业务下发指示方法， 该标志位的设置为 3 个比特， 每 个比特标识的内容分别是是否采用映射指示法、 SLPID指示法和 Short Basic CID指示法。 该比特位置 "0"为未采用对应的指示方法， 该比特置 "1" 为采用对应的指示方法。
S2、 MSS接收所述的业务指示消息， 提取标志位信息。
MSS在所述的业务指示消息中， 提取该标志位信息， 该标志位信息 使用前述的 3个比特承载。
53、 采用所述的标志位信息对应的业务指示方法判断是否有针对各 个睡眠组业务下发指令， 如果有进入步骤 S4， 如果没有进入步骤 S5。
MSS才艮据该 3个比特的置" 0"或者置 " , 即可得知本次业务指示消 息采用的业务指示方法。
在这里， 所述的 3个比特的设定， 既可以同时置 "0"或者置 "1", 也可 以部分置" 0"或者置 "Γ, 这也是本发明较现有技术灵活的一种体现。
54、 指示有业务下发的 MSS的睡眠组状态转为非激活状态， 并接收 所述的业务。
根据判断结果， 如果有针对该睡眠组的业务指示， 则说明有业务下 发指令， MSS将该睡眠组状态转为非激活状态， 接收所述的业务。
55、 MSS的睡眠组状态保持激活状态。
根据判断结果， 如果没有针对该睡眠组的业务指示， 则说明没有业 务下发指令， MSS的睡眠組状态保持激活状态。 如图 5 所示， 是本发明根据设置的标志位判断业务下发指示方法类 型的示意图。 其中， 该实施例中包括： 步骤 S51 , 提取标志位； 步驟 S52, 解析该标志位的信息； 步骤 S531 , 如果标志位中 Bit0=l , 则说明采用映 射指示法； 如果标志位中 Bitl=l , 则说明采用 SLPID指示法； 如果标志 位中 Bit2=l , 则说明采用 Short Basic CID指示法。
也就是说， 本发明实施例的标志位的设置， 可以携带的业务下发指 示方法包括映射指示法、 SLPID指示法和 Short Basic CID指示法。
本发明中， 所述直接采用 SLPID指示的方法是指在消息中直接标识 需要接受业务的睡眠组。
当所述的标志位标识的业务下发指示方式为睡眠组标识指示法时， 所述的业务指示消息中， 还携带睡眠组标识数量信息。
本发明在业务指示消息中设置标志位， 用以标识睡眠组的业务下发 指示方法， 可以灵活的携带多种业务下发指示方法， 避免了现有技术中 只能择一的选择业务下发指示方法的问题， 可以最大程度的减少业务指 示消息的开销， 大大节省了空口资源。
本发明提供的睡眠模式下业务指示消息发送装置， 包括：
标志信息设置单元， 用于在业务指示消息中设置标志信息， 标识睡 眠组的业务下发指示方式； 所述业务下发指示方式是单一方式或者至少 两种方式的组合；
发送单元， 用于发送所述业务指示消息。
所述装置可以位于基站内。
显然， 本领域的技术人员可以对本发明进行各种改动和变型而不脱 离本发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发 明权利要求及其等同技术的范围之内， 则本发明也意图包含这些改动和 变型在内。
