Description

组寻呼区域信息的通知方法和设备 本申请要求于 2011 年 8 月 23 日提交中国专利局, 申请号为 201110242935.7, 发明名称为 "组寻呼区域信息的通知方法和设备" 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
本发明涉及通信技术领域,特别涉及一种组寻呼区域信息的通知 方法和设备。 背景技术
机器类型通信 ( Machine-Type Communication, MTC )作为一种 新型的通信理念,其目的是将多种不同类型的通信技术有机结合,如: 机器对机器通信、 机器控制通信、 人机交互通信、 移动互联通信, 从 而推动社会生产和生活方式的发展。预计未来人对人通信的业务可能 仅占整个终端市场的 1/3, 而更大数量的通信是 MTC通信业务。 有 时, MTC通信又称为机器间 (Machine-To-Machine, M2M )通信或 物联网。
当前的移动通信网络是针对人与人 ( Human to Human , Η2Η )之 间的通信设计的, 如: 网络容量的确定等。 如果希望利用移动通信网 络来支持 MTC通信就需要根据 MTC通信的特点对移动通信系统的 机制进行优化,以便能够在对传统的人与人通信不受或受较小影响的 情况下, 更好地实现 MTC通信。
当前认识到的 MTC通信可能存在的一些特点有:
MTC设备具有低移动性;
MTC设备与网络侧进行数据传输的时间是可控的;
MTC 网络与网络侧进行的数据传输对数据传输对实时性要求不 高, 即: 具有时间容忍性;
MTC设备能量受限, 要求极低的功率消耗; MTC设备和网络侧之间只进行小数据量的信息传输
MTC设备可以以组为单位进行管理; 一个实际的 MTC设备可以具有上述的一个或多个特点。
对大量 M2M用户的通信进行管理的情况下, 一种可以提升管理 效率的方法是对具有某种或某些相同业务特性的用户将其规划为一 组, 以组的单位进行管理。 比如, 对一组用户, 需要通知其进行数据 上报。 目前在 3GPP ( Third Generation Partnership Project, 第三代移 动通信伙伴计划 )范畴讨论的一种可能方式是 SCS (服务器 )通知核 心网向该组用户发起寻呼( paging ), RAN ( Radio Access Network, 无线接入网)将寻呼信息发送到空口, 属于该群组的 M2M用户接收 到寻呼信息后即发起随机接入过程, 与网络建立通信链路后, 发送所 要求的数据。
目前所讨论的基于组为单位进行用户数据上报管理的方法,为了 避免某个组的大量用户在接收到组寻呼后集中发起随机接入导致网 络发生拥塞, 系统可以通过一定的接入时间随机化解决该问题; 也可 以通过为这部分 M2M 用户分配专用的 PRACH ( PhysicalRandom Access Channel, 物理随机接入信道)资源来减少对 H2H用户接入的 影响。
对于 UMTS ( Universal Mobile Telecommunications System, 通用 移动通信系统 )系统,核心网通过 Iu接口( Iu接口负责核心网和 RNC 之间的信令交互)控制面 RANAP ( Radio Access Network Application Part,无线接入网络应用部分 )消息,发送 paging消息给 RNC ( Radio Network Controller, 无线网络控制器), paging范围为 LA ( Location Area,位置区域)/RA( Routing Area,路由区域)。对于 LTE( Long Term Evolved, 长期演进) 系统, 核心网通过 SI接口 (S1接口提供无线 与核心网络连接)控制面 S 1 AP ( Application Part , 应用协议 ) 消息, 发送 paging消息给 eNB ( evolved Node B , 演进的 Β节点, 即基站), paging范围为 TA ( Tracking Area, 3艮踪区域)。 在实现本发明的过程中,发明人发现现有技术中至少存在以下问 题:
根据现有技术的介绍可知, 目前的寻呼是基于 LA/RA ( UMTS ) 或 TA ( LTE )的, 而在 M2M基于组的技术方案讨论中, 组寻呼是一 种有效的方案, 但是目前的寻呼机制限制了寻呼范围为 LA/RA ( UMTS )或 TA ( LTE ), 而 SCS希望获取数据的范围并不与 LA/RA ( UMTS )或 TA ( LTE )重合, 这样就降低了组寻呼的效率, 并可能 造成不必要的资源浪费。 发明内容
本发明实施例提供一种组寻呼区域信息的通知方法和设备,解决 现有的技术方案中基于组用户管理的情况下,不能准确的确定组寻呼 范围的问题。
为达到上述目的,本发明实施例一方面提供了一种组寻呼区域信 息的通知方法, 至少包括以下步骤:
RAN 设备接收到业务能力服务器 SCS ( Services Capability Server )发送的控制面消息,所述控制面消息中携带组寻呼区域信息; 所述 RAN设备根据所述组寻呼区域信息, 确定发起组寻呼的组 寻呼区域。 另一方面, 本发明实施例还提供了一种 RAN设备, 至少包括: 接收模块, 用于接收 SCS发送的控制面消息, 所述控制面消息 中携带组寻呼区域信息;
处理模块, 用于根据所述接收模块所接收到的组寻呼区域信息, 确定发起组寻呼的寻呼区域。 另一方面,本发明实施例还提供了一种组寻呼区域信息的通知方 法, 至少包括以下步骤: SCS向 RAN设备发送携带组寻呼区域信息的控制面消息, 以使 所述 RAN设备根据所述组寻呼区域信息确定发起组寻呼的寻呼区 域。 另一方面, 本发明实施例还提供了一种 SCS, 至少包括: 发送模块, 用于向 RAN设备发送携带组寻呼区域信息的控制面 消息, 以使所述 RAN设备根据所述组寻呼区域信息确定发起组寻呼 的寻呼区域。
与现有技术相比, 本发明实施例所提出的技术方案具有以下优 点:
通过应用本发明实施例的技术方案, RAN侧可以通过 SCS提供 的寻呼区域信息以及小区覆盖信息, 进一步细化组寻呼区域的范围, 从而, 在基于组管理用户的情况下, 能够更准确的确定寻呼范围, 提 高组寻呼效率, 避免组寻呼过程中寻呼范围过大造成的资源浪费, 通 过这样的处理,避免了现有技术中大量用户接收到组寻呼而发起随机 接入对 RAN负荷造成沖击, 以及对传统的 H2H用户造成影响。 附图说明

具体实施方式 如背景技术所述, 机器到机器通信是未来智能化发展的一种趋 势。 在第三代移动通信系统以及其长期演进系统中需要支持 MTC功 能。 而当前的通信系统网络是对人与人之间的通信设计的, 如系统容 量、 过载控制机制等。 在大量的 M2M通信应用场景中, MTC功能 的终端数量将远远大于 H2H的普通终端, 可能达到现有移动终端数 量的几十倍。 那么, 在某些应用场景下 (例如具有相同业务需求的 metering等 ) , 可以考虑对 M2M用户进行分组管理, 当 SCS需要针 对某一组 M2M用户进行相同的处理, 通过寻呼一组 M2M用户, 要 求 M2M 用户上报数据, 但是目前的寻呼机制限制了寻呼范围为 LA/RA ( UMTS )或 TA ( LTE ), 而 SCS希望获取数据的范围并不与 LA/RA ( UMTS )或 TA ( LTE ) 重合, 可能远小于 LA/RA ( UMTS ) 或 TA ( LTE ) 的范围, 这样就降低了组寻呼的效率, 并可能造成不 必要的资源浪费。
为了克服这样的缺陷,本发明实施例提出了一种组寻呼区域信息 的通知方法, 在基于组管理用户的情况下, 能够更准确的确定寻呼范 围。
如图 1所示,为本发明实施例所提出的一种组寻呼区域信息的通 知方法的流程示意图, 该方法具体包括以下步骤:
步骤 S101、 RAN 设备接收到业务能力服务器 SCS ( Services Capability Server )发送的控制面消息, 该控制面消息中携带组寻呼区 域信息。
在具体的实施场景中,本步骤中的控制面消息的传输过程实际是 通过核心网进行转发来完成的, 具体的, 本步骤中的操作过程实际为 RAN设备通过核心网设备接收到 SCS发送的控制面消息。
在实际应用中, 基于系统类型的差异, RAN设备的物理实体, 以及在核心网中的具体传输过程均会存在相应的区别, 具体说明如 下:
( 1 ) UMTS系统。
本步骤中的 RAN设备实际为 RNC, 相应的处理过程为 RNC通 过 Iu接口接收核心网设备所转发的 SCS发送的控制面消息。
进一步的, 此种情况下, SCS发送的控制面消息, 具体为控制面 RANAP协议的寻呼消息。
( 2 ) LTE系统。
本步骤中的 RAN设备实际为 eNB,相应的处理过程为 eNB通过 S1接口接收核心网设备所转发的 SCS发送的控制面消息。
进一步的, 此种情况下, SCS发送的控制面消息, 具体为控制面 SI AP协议的寻呼消息。
为了准确的传输相应的寻呼范围的信息, 上述的 SCS发送的控 制面消息中所携带的组寻呼区域信息具体包括以下两方面的内容。
A、 进行组寻呼的组标识信息。
B、 进行组寻呼的区域信息。
其中, 在具体的实施场景中, 进行组寻呼的区域信息具体可以为 以下类型的信息的任意一种:
以指定位置为中心,具有预设长度的半径的圆形区域的信息;或, 以指定位置为中心,具有预设长度的半径的扇形区域的信息;或, 以指定位置为方位点, 具有预设长度的长和宽的矩形区域的信 息; 或,
区域映射表中所包括的具体区域的编号信息。
当然, 在实际的应用场景中, 如果能够达到相应的寻呼范围确定 效果, 也可以采用其他类型的信息, 这样的变化并不影响本发明的保 护范围。
步骤 S102、 RAN设备根据组寻呼区域信息, 确定发起组寻呼的 寻呼区域。
同样的, 在实际应用中, 基于系统类型的差异, 本步骤的处理过 程也会存在相应的区别, 具体说明如下:
( 1 ) UMTS系统。
本步骤中的 RAN设备实际为 RNC , 相应的处理过程为:
RNC根据组寻呼信息和小区分布, 确定发送组寻呼的小区; RNC通过 Iub接口 (Iub接口是 RNC和 eNB之间的接口, 用来 传输 RNC和 eNB之间的信令以及来自无线接口的数据 )通知相应的 基站对 '〗、区发起组寻呼。
( 2 ) LTE系统。
本步骤中的 RAN设备实际为 eNB,相应的处理过程为 eNB根据 组寻呼信息和小区分布, 确定发送组寻呼的小区, 并对小区发起组寻 呼。
基于以上的说明,具体的系统类型变化并不会影响本发明的保护 范围, 同时, 如果有其他类型的系统可以实现相应的 SCS对 RAN设 备的携带组寻呼区域信息的控制面消息的传输过程, 同样可以应用本 发明实施例所提出的技术方案,这样的变化并不影响本发明的保护范 围。
相对应的, 在 SCS侧, 则是向 RAN设备发送携带组寻呼区域信 息的控制面消息的处理过程,具体的发送方式以及组寻呼区域信息的 携带方式参见上述说明, 与之相类似, 在此, 不再重复说明。
与现有技术相比, 本发明实施例所提出的技术方案具有以下优 点:
通过应用本发明实施例的技术方案, RAN侧可以通过 SCS提供 的寻呼区域信息以及小区覆盖信息, 进一步细化组寻呼区域的范围, 从而, 在基于组管理用户的情况下, 能够更准确的确定寻呼范围, 提 高组寻呼效率, 避免组寻呼过程中寻呼范围过大造成的资源浪费, 通 过这样的处理,避免了现有技术中大量用户接收到组寻呼而发起随机 接入对 RAN负荷造成沖击, 以及对传统的 H2H用户造成影响。 下面, 结合具体的应用场景, 对本发明实施例所提出的技术方案 进行说明。
结合前文所述的现有相关方案存在的问题,本发明实施例针对基 于组管理, 尤其是组寻呼过程中, RAN侧的设备如何有效进行寻呼 小区的确定提出解决方案。 本发明实施例所提出的技术方案的中心思想如下:
SCS将组寻呼区域信息通过核心网通知给 RAN设备, RAN设备 根据相应的信息确定在哪个或哪几个小区发起寻呼。 具体的, 相应的 寻呼区域信息可以是但不限于以下方面:
( 1 ) 以某一位置 (可以但不限于使用经纬度) 为中心, 半径固 定的圆。
( 2 ) 以某一位置 (可以但不限于使用经纬度) 为中心, 半径固 定的扇形。
( 3 ) 以某一位置 (可以但不限于使用经纬度) 为方位点, 长宽 固定的矩形等。
( 4 ) 区域映射表中具体区域的编号等。
RAN根据寻呼区域信息和小区覆盖情况, 确定具体发起寻呼的 小区。
以下针对 UMTS系统和 LTE系统分别给出相应的实施例。
如图 2所示, 为本发明实施例所提出的一种 UMTS的应用场景 中的寻呼区域信息的通知方法的流程示意图, 该方案的具体步骤如 下:
步骤 S201、 SCS向核心网传输携带组寻呼相关信息的 paging消 步骤 S202、 核心网可以通过 Iu接口控制面 RANAP 协议的 PAGING消息将组寻呼相关信息通知 RNC。
其中, 组寻呼区域信息可以是但不限于绝对地理位置区域信息, 区域映射表中的索引等。
对现有 RANAP协议的 PAGING消息的一种可能的修改方式如表 1所示。

步骤 S203、 RNC接收到上述信息后, 根据组寻呼区域信息和小 5 区分布,确定发送组寻呼的小区, RNC通过 Iub接口通知相应的基站 设备。
步骤 S204、 基站设备向相应的小区发起寻呼过程。 如图 3所示, 为本发明实施例所提出的一种 LTE系统的应用场 0 景中的组寻呼区域信息的通知方法的流程示意图,该方案的具体步骤 如下:
