Description

一种上行调度方法及装置
技术领域
本发明涉及通信技术领域, 尤其涉及一种上行调度方法及装置。 背景技术
通用分组无线业务( General Packet Radio Service, GPRS )技术已经在无线 通信网络中得到了广泛应用。 GPRS网络通过分组交换( Packet Switch )技术, 实现了 M2M ( Machine to Machine, 机器对机器)的分组业务数据传输, 为用户 提供更为丰富的服务类型。
在 M2M分组业务数据传输中 ,终端和网络侧之间通过数据块传输分组业务 数据。 网络侧通过在下行数据块中携带 USF ( Uplink State Flag, 上行链路状态 标识)对终端进行上行调度, 指示终端在 PDCH ( Packet Data Channel, 分组数 据信道) 的下一调度时间发送上行分组业务数据。
在 GSM ( Global System for Mobile Communications,全球移动通讯)系统中, USF一般在下行数据块的数据块块头中携带,占用 3个比特位,取值范围为 0~7。 USF的不同取值用于调度不同的终端, 当 USF取值为 7时, 表示 USF无效, 网络侧不进行上行调度。
目前, M2M ( Machine to Machine, 机器对机器 )业务主要以分组业务为主, 实现 M2M业务的终端常常会被部署在地下室或密闭空间。为了达到较好的覆盖 效果, 需要在无线网络的空口釆用覆盖增强的相关技术。
为了达到覆盖增强的需求, 可以通过在网络侧对下行数据块进行连续重复 发送的方式, USF作为下行数据块的一部分也需要重复发送。 进行数据块重复 发送时, USF被设置为相同的取值, 调用同一终端。 终端在将重复发送的数据 块全部接收完毕, 将各数据块进行合并后, 才能解码出 USF取值, 将解码出的 USF取值与预先分配的 USF取值进行匹配, 若匹配, 则在 PDCH的下一调度时 间发送上行分组业务数据。 然而, USF 是可以独立解码的, 在重复发送的最后 一个数据块之前发送的每个数据块中都携带有 USF, 可这些 USF虽然对终端进 行了上行调度, 但并未触发终端发送上行分组业务数据, 即在发送最后一个数 据块之前发送的各数据块的期间内并未进行上行分组业务数据的发送, 造成了 上行资源的浪费。 发明内容

S101 : 确定需要重复发送的下行数据块。
S102: 在需要重复发送的各下行数据块中, 携带具有不同取值的传统 USF。 本发明实施例中在需要重复发送的各下行数据块中携带的 USF即是下行数 据块中原始携带的 USF, 本发明实施例以下为描述方便, 下行数据块中原始携 带的 USF称为传统 USF。传统 USF—般是通过不同的取值对不同的传统终端进 行上行调度, 本发明实施例中传统终端是指不需要覆盖增强的终端。
S103: 在需要重复发送的各下行数据块中, 携带具有相同取值的 RUSF。 本发明实施例中在需要重复发送的各下行数据块中携带的 RUSF,专用于对 需要覆盖增强的终端进行上行调度。 本发明实施例中 RUSF具有相同取值, 以 用于对需要覆盖增强的终端进行上行调度。
S104: 下发携带有 RUSF以及传统 USF的下行数据块。
本发明实施例中在完成下发重复的各下行数据块之后, 需要覆盖增强的终 端,将获取到的各下行数据块中的 RUSF进行合并后,解码 RUSF,正确解码后, 在 PDCH的下一调度时间发送上行分组业务数据。 在下发重复的各下行数据块 期间, 传统终端可对获取到的下行数据块中携带的传统 USF进行解码, 正确解 码后, 在 PDCH的下一调度时间上发送上行分组业务数据。
本发明实施例中在需要重复发送的下行数据块中携带具有不同取值的传统 上行链路状态标识以及具有相同取值的重复上行链路状态标识, 即本发明实施 例中在原有下行数据块中增加了用于对需要覆盖增强的终端进行上行调度的重 复上行链路状态标识, 而对于传统终端进行上行调度的传统上行链路状态标识 无需更改为相同取值, 可保持下行数据块中原携带的传统上行链路状态标识的 取值不变。 故, 通过本发明实施例, 在发送重复的下行数据块期间, 可利用传 统上行链路状态标识对传统终端进行上行调度并发送上行分组业务数据, 利用 重复上行链路状态标识对需要覆盖增强的终端进行上行调度并发送上行分组业 务数据, 充分利用了上行资源, 提高了上行资源利用率。
本发明实施例以下将结合实际应用对在需要重复发送的下行数据块中携带
RUSF和传统 USF的过程进行详细说明。
本发明实施例 S103中在需要重复发送的各下行数据块中, 携带具有相同取 值的 RUSF,可在各下行数据块的数据块头中,分别添加具有相同取值的 RUSF, 以使需要覆盖增强的终端在获取到该携带有 RUSF 的下行数据块, 能够较快的 解码得出该下行数据块是对自身进行上行调度的下行数据块。 据块块头中部分原有信息的比特位进行缩减, 得到空闲的比特位, 将该得到的 空闲的比特位, 作为用于表征 RUSF的比特位。
可选的, 本发明实施例中可将下行数据块的数据块头中用于表征数据块序 号的 BSN ( backward Sequence Number, 后向序号)比特位缩减, 得到空闲的比 特位, 将得到的空闲的比特位, 作为用于表征 RUSF 的比特位, 以减少对数据 块块头的改变。
需要说明的是, 进行下行数据块接收的终端与进行上行调度的终端可以不 是同一终端。 本发明实施例中对数据块块头修改的下行数据块是发送给需要覆 盖增强的终端的, 该需要覆盖增强的终端可对 RUSF进行解码以及上行分组业 务数据的发送, 并可对除 RUSF以外的其它用于下行数据传输的信息进行解码, 进行下行分组业务数据的传输。
本发明实施例以 EGPRS ( Enhanced Data Rate for GSM Evolution , 增强型数 据速率 GSM演进技术) 的 MCS ( Modulation and Coding Scheme, 调制与编码 策略) -l~ MCS-4为例, 对在下行数据块的数据块块头中添加 RUSF进行说明。
表 1所示为现有携带 USF的数据块块头结构示例,表 1中 USF占用三个比 特位, 取值范围为 0~7。 BSN1用于表征数据块序号, 占用 11个比特位, 本发 明实施例中可将 BSN1 占用的比特位缩减 3个比特位, 利用缩减得到的 3个比 特位表征 RUSF , 如表 2所示。
Figure imgf000018_0001
表 1
表 2
表 2中 RUSF占用 3个比特位,取值范围为 0~7 , 同样 RUSF不同的取值可 以用于对不同的终端进行上行调度。 表 2 中在数据块的块头中携带有 USF 和 RUSF , USF可以保留原有的取值, 在发送重复下行数据块期间对传统终端进行 上行调度。 RUSF取值相同, 用于对需要覆盖增强的终端进行上行调度。
为避免解码 RUSF 的终端发送重复上行数据块与发送传统上行数据块发生 冲突, 本发明实施例中在需要重复发送的各下行数据块中的最后一个数据块中, 携带无效的传统 USF , 例如可携带取值为 7的传统 USF , 以使最后一个下行数 据块仅调度解码 RUSF 的终端。 在除最后一个数据块以外的其它需要重复发送 的各下行数据块中, 携带有效的传统 USF , 例如携带取值不为 7的传统 USF , 用于调度解码传统 USF的传统终端。 示意图。 图 6中下行数据块 B0为传统的下行数据块, 可釆用诸如表 1所示的数 据块块头结构, 传统终端获取到下行数据块 BQ并正确解码 USF值后, 可对应发 送上行数据块:^。 下行数据块 B B^为需要 N次重复发送的下行数据块, 故 本发明实施例中下行数据块 B^BNW的数据块块头结构可釆用诸如表 2的数据块 结构,其中 USF取值不同, RUSF取值相同。本发明实施例中例如可以设置 RUSF 取值为 0。 在下发的前 N-1 个下行数据块, 即下行数据块 Β^ΒΝ可设置 RUSF 取值为 0 , USF取值不为 7 , 其中 USF的具体取值可依据下行数据块原本需要 调度的终端来确定。 故在发送下行数据块 ^期间, 需要覆盖增强的终端将 获取到的每个下行数据块进行緩存, 而传统终端则可按原有的上行调度方式, 单独解码接收到的下行数据块块头中携带的 USF取值, 并可以在对应的上行信 道中发送上行数据块 B2~BN+1。 在下发的最后一个下行数据块 BN+1中设置 RUSF 取值为 0 , USF取值为 7 , 即最后一个下行数据块携带的 USF是无效的, 对传 统终端不进行上行调度, 解码 RUSF的终端在接收到下行数据块 BN+1后, 将获 取的需要 N次重复发送的下行数据块 B^BNW获取完毕, 此时对 RUSF值进行 解码, 若正确解码得到的 RUSF值与预先分配的值相同, 则在对应的上行信道 上开始发送上行数据块 BN+2
本发明实施例中在需要重复发送的下行数据块中携带具有不同取值的传统 上行链路状态标识以及具有相同取值的重复上行链路状态标识, 即本发明实施 例中在原有下行数据块中增加了用于对需要覆盖增强的终端进行上行调度的重 复上行链路状态标识, 而对于传统终端进行调度的传统上行链路状态标识无需 更改为相同取值, 可保持下行数据块中原携带的传统上行链路状态标识的取值 不变。 故, 通过本发明实施例, 在发送重复的下行数据块期间, 可利用传统上 行链路状态标识进行传统终端的上行调度, 利用重复上行链路状态标识进行接 收重复数据的终端进行上行调度, 充分利用了上行资源, 提高了上行资源利用 率。
本发明的另一实施例中以终端侧实现上行调度的过程为例进行说明, 图 3 所示为本发明另一实施例提供的上行调度方法的实现流程图。 图 7 中所示方法 的执行主体可以是终端设备, 当然该方法的执行主体也可以是终端设备中的各 个部件, 本发明实施例并不引以为限。 如图 7所示, 该方法包括:
S201 : 确定终端类型。
本发明实施例中终端类型包括不需要覆盖增强的传统终端和需要覆盖增强 的终端。
S202a: 若确定的终端类型为不需要覆盖增强的传统终端, 则获取并解码网 络侧发送的下行数据块中携带的传统上行链路状态标识。
本发明实施例中, 不同取值的传统上行链路状态标识用于对不同的传统终 端进行上行调度。 S202b: 确定的终端类型为需要覆盖增强的终端, 则获取并解码网络侧重复 发送的各下行数据块中携带的重复上行链路状态标识。
本发明实施例中, 各下行数据块中携带的重复上行链路状态标识具有相同 取值, 用于对需要覆盖增强的终端进行上行调度。
S203: 根据解码结果触发上行分组业务数据的发送。
可选的, 本发明实施例中获取网络侧重复发送的各下行数据块中携带的重 复上行链路状态标识, 可通过解析网络侧重复发送的各下行数据块的数据块块 头, 得到的重复上行链路状态标识。 送的下行数据块的数据块块头结构进行相应的解析的, 例如若重复上行链路状 态标识的比特位是在数据块块头中原有信息的比特位缩减的位置, 则对该缩减 位置处的数值进行解析, 得到重复上行链路状态标识。
需要说明的是, 本发明实施例中终端侧进行上行调度的实现过程是适应网 络侧发送的下行数据块结构的, 故对本发明实施例中终端侧进行上行调度的过 程描述不够详尽的地方, 可参考网络侧的相关描述, 在此不再赘述。
本发明实施例提供的上行调度方法, 根据确定的终端类型获取并解码传统 上行链路状态标识或者重复上行链路状态标识, 故通过本发明实施例, 在发送 重复的下行数据块期间, 传统终端可利用传统上行链路状态标识进行上行调度 并发送上行分组业务数据, 需要覆盖增强的终端利用重复上行链路状态标识进 行上行调度并发送分组业务数据, 在发送下行数据块期间内都进行了上行分组 业务数据的发送, 充分利用了上行资源, 提高了上行资源利用率。
