Description

对上行不连续发射状态的控制方法、 系统及装置
本申请要求于 2011 年 6 月 20 日提交中国专利局、 申请号为 201110166284. 8 , 发明名称为 "对上行不连续发射状态的控制方法、 系统及装 置" 的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及在时分同步码分多址（TD-SCDMA )系统中对射频信号的控制技 术，特别涉及一种在 TD-SCDMA系统中对上行不连续发射（DTX, Di s cont inuous transmi s s ion ) 态的控制方法、 系统及装置。 背景技术
在 TD-SCDMA 系统中， 在终端与网络侧之间传输 DTX 的射频信号是 3GPP国际标准定义的一种标准技术和功能。 当 TD-SCDMA系统中的终端与 网络侧之间建立无线链路后，如果终端和网络侧之间暂时不进行通信交互， 即 终端或网络侧没有传输数据块提供给任何给定的编码复合传输信道 ( CCTrCH )用于承载在射频信号上发射时， 终端或网络侧就会关闭自身的射 频发射机， 停止射频信号的连续发射， 并进入 DTX状态。 终端与网络侧之间通过无线链路传输射频信号时， 根据不同的发射方向， 可以分为上行 DTX的射频信号和下行 DTX的射频信号。 其中， 上行 DTX的 射频信号表示终端向网络侧发射的非连续的发射射频信号，这时发射的射频信 号称为特殊突发（special burst ),下行 DTX的射频信号表示网络侧向终端发射 的非连续的发射射频信号， 这时发射的射频信号也为特殊突发。 图 1为现有技术的上行 DTX的射频信号与上行连续发射的射频信号进行 发射的对比示意图， 如图所示， 对于非上行 DTX的射频信号， 在一个发射周 期内， 比如该发射周期为 40毫秒， 非上行 DTX的射频信号中每个无线帧， 也 就是每 10毫秒一个无线帧都携带有数据块发送； 对于上行 DTX的射频信号， 在一个发射周期内， 也就是特殊突发产生周期（ SBGP, Special burst generation period ) 内， 设该 SBGP为 40毫秒， 除了第一个无线帧， 也就是第一个 10毫 秒要发射的无线帧内， 发射特殊突发， 剩余时间的无线帧内不发射任何突发。
在网络侧与终端建立无线链路后，为了使得终端可以进入上行 DTX状态， 釆用了图 2所示的方法， 图 2为现有技术终端进入上行 DTX状态的方法流程 图， 其具体步骤为：
步骤 201、 网络侧向终端发送上行物理信道控制 （UPLINK PHYSICAL
CHANNEL CONTROL ) 消息， 在该消息携带有进入上行 DTX状态指示； 步骤 202、 终端接收到该消息后， 确认要进入上行 DTX状态， 关闭自身 的射频发射机， 停止射频信号的连续发射， 进入上行 DTX状态。
可以看出，在终端进入上行 DTX状态时，只需要发射不连续的射频信号， 而不发送连续的射频信号。 由于没有连续的射频信号发射， 终端在进入上行 DTX状态时具有省电和降干扰等好处， 但同时使得网络侧对终端的同步控制 和功率控制的周期变得稀疏，特别是在诸如高速移动、深衰落和强干扰等恶劣 和复杂通信场景下。 当终端进入上行 DTX状态时， 由于终端发射的上行 DTX 的射频信号本身具有不连续的信号发射特性， 与非上行 DTX的射频信号发射 特性相比， 网络侧和终端之间的无线链路交互和控制效率明显降低，如果网络 侧对终端的同步和功率控制机制的周期远远小于上行 DTX状态的发射周期， 就会使得网络侧无法在网络侧对终端的同步和功率控制机制的周期内获取到 终端发送的上行射频信号，导致终端与网络侧之间失步或断开无线链路等异常 现象。 为了克服上述问题，当网络侧无法在网络侧对终端的同步和功率控制机制 的周期内获取到终端发送的上行射频信号时， 需要指示终端关闭上行 DTX状 态， 进行非上行 DTX的射频信号发射的过程。 但是， 现有的技术标准及实现 方法中网络侧在指示终端进入上行 DTX状态时， 上行物理信道控制消息携带 进入上行 DTX状态指示缺省上行 DTX状态，就是默认上行 DTX状态为开启， 并始终保持有效， 但却没有任何方法和过程指示终端关闭上行 DTX状态， 这 就意味着终端的上行 DTX状态无法在开启和关闭之间进行控制。 发明内容

为使本发明的目的、技术方案及优点更加清楚明白， 以下参照附图并举实 施例， 对本发明作进一步详细说明。
由于现有的技术标准及实现方法中网络侧在指示终端进入上行 DTX状态 时， 没有任何方法和过程指示终端关闭上行 DTX状态， 使得终端的上行 DTX 状态无法在开启和关闭之间进行控制， 对于进入上行 DTX状态的终端， 会使 得网络侧无法在网络侧对终端的同步和功率控制机制的周期内获取到终端发 送的上行射频信号， 导致终端与网络侧之间失步或断开无线链路等异常现象。
为了克服这个问题，本发明在网络侧要关闭终端处于的上行 DTX状态时， 向终端发送不携带特殊突发时序安排指示（ Special Burst Scheduling )的上行物 理信道控制 （ UPLINK PHYSICAL CHANNEL CONTROL ) 消息， 指示终端关 闭上行 DTX状态， 打开自身的射频发射机， 恢复发射连续发射的射频信号。
本发明网络侧确定要关闭终端进入的 DTX状态之前， 网络侧检测到终端 由于无法在网络侧对终端的同步和功率控制机制的周期内获取到终端发送的 上行射频信号， 而出现诸如与网络侧之间失步或断开无线链路等异常现象。
在现有的上行物理信道控制消息中包含的部分内容如表一所示 ,
Figure imgf000008_0001
表 一
当特殊突发时序安全指示包括在上行物理信道控制消息中时 ,在现有的上 行物理信道控制消息中还必须携带 SBGP, 主要用于对上行 DTX状态的周期 长度进行配置， 其具体含义如表二所示： 信息元素 /组 属性 重 参数值 参数值描述 名称
SBGP 必须 整 数 参数值代表无线 携带 ( 0...7 ) 帧个数， 无线帧时间 长度为 10毫秒
0=2 个无线帧长 度， 1=4 个无线帧长 度， 2=8 个无线帧长 度， 3=16个无线帧长 度， 4=32个无线帧长 度， 5=64个无线帧长 度， 6=128个无线帧长 度， 7=256个无线帧长 度
Figure imgf000009_0001
从表二可以看出， SBGP 的取值范围及为 0~7 , 所对应的时间周期为 20 毫秒〜 2560毫秒。
在表一中的特殊突发时序安排指示的属性为可选，说明是否在上行物理信 道控制消息中携带特殊突发时序安排指示是根据需要配置。在现有技术中， 当 上行物理信道控制消息中携带有特殊突发时序安排指示时，则表明需要对终端 处于上行 DTX状态的 SBGP进行更新， 所以在上行物理信道控制消息中还携 带有设置了参数值的 SBGP, 如果不携带特殊突发时序安排指示， 则终端处于 上行 DTX状态的 SBGP不变。
本发明将特殊突发时序安排指示的可选属性进行利用，在对不携带时进行 重新定义， 用于作为关闭终端的上行 DTX状态的指示， 即：
当特殊突发时序安排指示携带在上行物理信道控制消息中时 ,指示终端的 上行 DTX状态为开， 也就是与现有标准定义保持不变， 并且按照上行物理信 道控制消息携带的 SBGP参数值更新上行 DTX状态的时间周期； 这里， 如果 调整， 直接维护处于上行 DTX状态即可；
当特殊突发时序安排指示不携带在上行物理信道控制消息中时，指示终端 的上行 DTX状态为关， 也就是将现有标准定义更改为上行 DTX状态的关闭。
也就是说 , 网络侧通过 UPLINK PHYSICAL CHANNEL CONTROL 消息 中是否携带 IE "Special Burst Scheduling"，显式的通知 UE开启或关闭 UL DTX。 UE根据从网络侧接收的 UPLINK PHYSICAL CHANNEL CONTROL 消息中 是否携带 IE "Special Burst Scheduling" , 开启或关闭 UL DTX。 如果消息中携 带了 IE "Special Burst Scheduling" , 则 UE将启动 UL DTX操作； 如果不携带 IE "Special Burst Scheduling" , 则 UE将关闭 UL DTX操作。
UL DTX的开启流程：
1)当网络侧判决需要 UE启动 UL DTX时， 网络侧向 UE发送 UPLINK PHYSICAL CHANNEL CONTROL 消息， 消息中携带 IE " Special Burst Scheduling"；
2)当 UE收到来自网络侧的 UPLINK PHYSICAL CHANNEL CONTROL 消息时， 判断其中是否携带了 IE "Special Burst Scheduling" ; 如果携带了 IE " Special Burst Scheduling" , 则 UE启动 UL DTX, 在物理层没有数据发送时， UE应根据 IE "Special Burst Scheduling"中配置的周期长度进行 UL DTX操作。
UL DTX的关闭流程：
1)当网络侧判决需要 UE关闭 UL DTX时， 网络侧向 UE发送 UPLINK PHYSICAL CHANNEL CONTROL 消息， 消息中不携带 IE "Special Burst
Scheduling"；
2)当 UE收到来自网络侧的 UPLINK PHYSICAL CHANNEL CONTROL 消息时， 判断其中是否携带了 IE "Special Burst Scheduling" ; 如果没有携带 IE
"Special Burst Scheduling" , 则 UE将关闭 UL DTX操作， 在物理层没有数据 UE将持续发送 special burst。 设 UE与网络侧已经建立无线链路， 且 UE进入上行 DTX状态， 上行 DTX状 态的时间周期为上行物理信道控制消息携带的 SBGP参数值， 也可以为 SBGP 参数缺省值， 比如 SBGP为 2, 即 80毫秒， 其具体步骤为：
步骤 301、 网络侧确定终端要关闭上行 DTX状态；
在本步骤之前，网络侧可以检测到与终端之间的无线通信链路异常或接收 到终端发起的要关闭上行 DTX状态请求， 这里不限定；
步骤 302、 网络侧发送发送不携带特殊突发时序安排指示的上行物理信道 控制消息给终端， 指示终端关闭上行 DTX状态， 即指示终端打开自身的射频 发射机， 恢复发射连续发射的射频信号。
在该实施例中， 网络侧当需要更改处于上行 DTX状态的终端的上行 DTX 状态的时间周期时，也可以携带特殊突发时序安排指示及 SBGP参数值，这样， 就可以指示终端更改所处于上行 DTX状态的时间周期了。
具体地说，网络侧向终端发送携带特殊突发时序安排指示及特殊突发产生 周期的上行物理信道控制消息，指示终端根据所携带的突发时序安排指示确认 继续处于上行 DTX状态， 指示终端根据所携带的特殊突发产生周期确定是否 调整处于上行 DTX状态的时间周期： 当所述特殊突发产生周期为终端处于
DTX状态的当前时间周期时， 指示不调整； 否则， 指示终端根据特殊突发产 生周期调整处于上行 DTX状态的时间周期。
在本发明中， 网络侧可以为全球陆地接入网络（UTRAN )侧。 设 UE与网络侧已经建立无线链路， 且 UE进入上行 DTX状态， 上行 DTX状 态的时间周期为上行物理信道控制消息携带的 SBGP参数值， 也可以为 SBGP 参数缺省值， 比如 SBGP为 2, 即 80毫秒， 其具体步骤为：
步骤 401、 终端判断是否接收到上行物理信道控制消息， 如果是， 则执行 步骤 402; 如果否， 则返回步骤 401继续接收上行物理信道控制消息；
步骤 402、 终端确定该消息是否携带了特殊突发时序安排指示， 如果否， 则执行步骤 403; 如果是， 则执行步骤 404;
步骤 403、 终端关闭上行 DTX状态， 即打开自身的射频发射机， 恢复发 射连续发射的射频信号；
步骤 404、 终端继续保持上行 DTX状态， 根据所携带的 SBGP参数值更 新配置所处于的上行 DTX状态周期。
在本发明中，携带在上行物理信道控制消息中的 SBGP参数值的下发， 与 现有技术保持一致。 在本实施例中，当确认携带有特殊突发时序安排指示及特殊突发产生周期 根据所携带的特殊突发产生周期确定是否调整处于上行 DTX状态的时间 周期： 当所述特殊突发产生周期为终端处于 DTX状态的当前时间周期时， 不 调整； 否则， 根据特殊突发产生周期调整处于上行 DTX状态的时间周期。

所述网络侧，还用于通过携带特殊突发时序安排指示及特殊突发产生周期 的上行物理信道控制消息 ,指示终端根据所携带的特殊突发产生周期确定是否 调整处于上行 DTX状态的时间周期：当所述特殊突发产生周期为 DTX状态的 当前时间周期时， 指示终端不调整； 否则， 指示终端根据特殊突发产生周期调 整处于上行 DTX状态的时间周期；
所述终端，还用于根据从网络侧接收的携带有特殊突发时序安排指示及特 殊突发产生周期的上行物理信道控制消息， 确定是否调整处于上行 DTX状态 的时间周期： 当所述特殊突发产生周期为终端处于 DTX状态的当前时间周期 时， 不调整； 否则， 根据特殊突发产生周期调整处于上行 DTX状态的时间周 期。
