Description
一种连接帧号获取方法、 通信系统以及设备
本申请要求于 2007 年 7 月 26 日提交中国专利局、 申请号为 200710128485.2、 发明名称为 "一种连接帧号获取方法及通讯系统以及相关设 备"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
本发明涉及通信领域, 尤其涉及一种连接帧号获取方法、通信系统以及设 备。
背景技术
宽带码分多址接入 ( WCDMA, Wideband Code Division Multiple Access ) 系统引入高速链路分组接入 ( HSPA , High Speed Package Access )后, 处理能 力得到加强,为了增强用户设备的移动性,需要在无线网络控制器间接口(IUR 接口 )上支持 HSPA功能。
现有技术中, 当信令无线承载(SRB, Signaling Radio Bearer )或业务承 载在 HSPA上(即下行数据承载在 HSDPA上、 上行数据承载在 HSUPA时 ) 时, 由于不存在专用传输信道(DCH, Dedicated Channel ), 所以无法进行传 输信道同步, 导致服务无线网络控制器 (SRNC , Serving Radio Network
Controller )无法获取连接帧号 ( CFN, Connection Frame Number )„
发明内容
本发明实施例提供一种连接帧号获取方法、通信系统以及设备, 能够在应 用 HSPA的情况下获取 CFN。
本发明实施例提供的连接帧号获取方法, 包括: 通过共享高速数据通道帧 协议向基站发送包括无线网络控制器时间信息的下行节点同步请求;接收所述 基站通过共享高速数据通道帧协议发送的包括所述基站时间信息的上行节点 同步响应; 才 据预置的无线网络控制器帧号、预置的帧偏移量、 所述无线网络 控制器时间信息以及所述基站时间信息获得连接帧号。

控制器帧号、预置的帧偏移量、所述无线网络控制器时间信息以及所述基站时 间信息获得连接帧号;
所述基站,用于向服务无线网络控制器发送包括基站时间信息的上行节点 同步响应。
本发明实施例提供的网络设备, 包括: 发送单元, 用于通过共享高速数据 通道帧协议向基站发送包括无线网络控制器时间信息的下行节点同步请求;接 收单元,用于通过共享高速数据通道帧协议接收基站发送的包括基站时间信息 的上行节点同步响应; 计算单元, 用于根据预置的无线网络控制器帧号、预置 的帧偏移量、所述无线网络控制器时间信息以及所述基站时间信息通过计算获 得连接帧号。

从以上技术方案可以看出, 本发明实施例具有以下优点:
本发明实施例中由于网络设备与基站之间通过同步过程交互网络设备与 基站之间的时间信息, 使得网络设备可以根据自身的 RFN, 网络设备与基站 的时间差以及预置的帧偏移量计算 CFN, 所以能够在应用 HSPA的情况下获 取到 CFN。

图 3为本发明实施例中通信系统实施例示意图;
图 4为本发明实施例中 RNC实施例示意图;
图 5为本发明实施例中基站实施例示意图。
具体实施方式
本发明实施例提供了一种连接帧号获取方法及通信系统以及相关设备,用 于在应用 HSPA的情况下获取 CFN。
本发明实施例中, 在应用 HSPA的环境中, 为了能够获取到 CFN, 需要
-3- 在 IUR接口信令协议 25435 中使承载共享高速数据通道 (HS-DSCH , High-Speed Downlink Shared Channel )的帧协议 ( FP, Frame Protocol )支持节 点同步, 具体的方式在本实施例中为修改协议中有关 HS-DSCH的参数信息, 所述 HS-DSCH, 又称为高速下行链路共享信道, 如下表所示:
表 1
上表中, HS-DSCH的节点同步的参数由现有技术中的 "no"修改为本发明 实施例中的" yes", 即可以使得 FP支持节点同步, 即 RNC可以通过修改后的 共享高速数据通道帧协议向基站发送节点同步请求,并能得到基站反馈的节点 同步响应。
可以理解的是, 同样可以采用其他的方式使得 FP支持节点同步, 此处不 作限定。
请参阅图 1 ,图 1所示的为本发明实施例中节点同步过程示意图,具体为:
SRNC 通过共享高速数据通道帧协议向漂移无线网络控制器 (DRNC, Drift Radio Network Controller )发送包含 SRNC本地时间信息 Tl的下行节点同步 请求, DRNC向基站转发包含 T1的下行节点同步请求, 基站接收到该请求的 时间为 T2,之后对该请求进行处理, 于 T3时刻通过共享高速数据通道帧协议 反馈上行节点同步响应, 该响应中分别包含有( T1, T2, T3 )。 DRNC将上行 节点同步响应反馈至 SRNC后完成节点同步。
需要说明的是,本实施例中所述共享高速数据通道帧协议, 与现有的共享 高速数据通道帧协议不同,就是预先设置所述共享高速数据通道帧协议中节点 同步的参数为支持节点同步。
请参阅图 2, 本发明实施例中 CFN获取方法实施例流程包括:
201、 RNC通过共享高速数据通道帧协议向基站发送包含自身时间信息的 下行节点同步请求;
本实施例中, 具体步骤为:
SRNC通过共享高速数据通道帧协议向 DRNC发送包含 SRNC时间信息 的下行节点同步请求;
DRNC向基站转发下行节点同步请求。
202、 接收基站通过共享高速数据通道帧协议反馈的包含基站时间信息的 上行节点同步响应;
本实施例中, 具体步骤为:
DRNC接收通过共享高速数据通道帧协议基站反馈的包含基站时间信息 的上行节点同步响应;
DRNC将该响应信息转发到 SRNC。
203、 将无线网络控制器的时间信息与基站的时间信息的差值作为时间差 (即计算时间差);
请一并参看图 1 , 本实施例中此处的时间差为 T1 与 T2 的差值, 即
RfiiBfiiDiff=Tl - T2。
204、 才 据预置的无线网络控制器帧号、 预置的帧偏移量、 无线网络控制 器时间信息以及基站时间信息获得连接帧号(即计算连接帧号)。
本实施例中, 帧偏移量 Frame Offset的获取过程为: RNC根据预置条件分
配的 Frame Offset, 即 IUR接口无线链路的 Frame Offset。 本实施例中, 预置 条件为符合协议规定的取值范围 , 具体规定的取值范围为 0 ~ 255之间的任意 整数。 需要说明的是, 在建立新的无线链路时, 如果新的无线链路不需要参考 旧无线链路的时间信息, 此时 RNC可以随意设置 Frame Offset, 否则, 就需要 UE来测量新旧无线链对应小区的时间差, 然后得到 Frame Offset, 其中, UE 测量新旧无线链对应小区的时间差的过程,对于本领域技术人员来说已为公知 技术, 在此不再赞述。
本实施例中无线网络控制器帧号 RFN的获取过程为: 根据预置条件设置 无线网络控制器帧号, 比如, RNC刚启动的时候的 RFN设置为 0, 然后按周 期递增; 获取设置的无线网络控制器帧号, 即 RNC侧的时间。
本发明实施例中 RNC侧采用的计算 CFN的方式与终端侧计算 CFN的方 式相同, 因此, RNC侧可以利用终端侧计算 CFN的方式来计算 CFN。
终端侧计算 CFN的方式为利用系统帧号码( SFN, System Frame Number ) 减去 Frame Offset, 具体为:
CFN = ( SFN - Frame Offset ) mod 256
其中, SFN是基站控制下的小区的时间值, 这个时间值与基站的时间值 BFN之间的间隔最大为 0.09个 BFN的大小, 所以在计算 CFN的时候可以忽 略 SFN与 BFN的差别。
本实施例中 , SFN近似由( RFN - RfiiBfnDiff+ 327680 ) mod 327680 ) /80 组成,无线网络控制器帧号 RFN是以 0.125ms为单位进行计数,即是每 327680 次(40.96s )为一次循环, 由于 CFN是以 10ms为单位进行计数, 所以要将计 算结果除以 80以换算为 CFN的单位, 具体公式如下:
CFN= ( ( ( RFN - RfiiBfiiDiff + 327680 ) mod 327680 ) /80 - FrameOffset ) mod 256。
