Description

一种用户设备及利用扩展寻呼周期进行寻呼的方法和系统
技术领域 备, 以及一种利用扩展寻呼周期进行寻呼的方法和系统。
背景技术
机器到机器(M2M, Machine to Machine )通信是指机器之间建立连接 的所有通信技术和手段。 M2M通信理念目前是众多通信设备商和电信运营 商的关注焦点。 目前全球的机器数量比人的数量要多很多, 因此可以预见到 M2M技术存在这巨大的需求。
对 M2M通信应用场景研究表明在移动网络上提供 M2M通信具有潜在 的市场前景。 现有的移动通信网络主要针对人与人的通信进行设计, 而对机 器与机器, 人与机器的通信则优化不足。 此外, 运营商如何能够以低成本提 供 M2M通信服务, 也是 M2M通信部署能否成功的关键。针对 M2M业务对 系统的各种新要求, 为了增强移动网络在这方面的竟争力, 有必要对现有的 移动网络进行优化, 以更有效地支持 M2M通信。
基于以上情况, 有必要研究移动网络支持 M2M通信的解决方案, 解决 方案应当最大限度重用现有网络, 以降低大量 M2M通信对网络造成的影响 以及运营维护的复杂度。
为了有效地利用移动网络资源, 第三代合作伙伴计划 (3GPP , 3rd Generation Partnership Project )提出了机器类型通信 ( MTC, Machine Type Communication ) , 即机器对机器( Machine to Machine )、机器对人 ( Machine to Man )进行通讯的业务, 其业务范围远远超出了以往人对人 ( H2H, Human to Human )之间的通讯。 MTC在接入控制、 计费、 安全性、 服务质量(QoS, Quality of Service )、 业务模式等方面与现在的 H2H通讯模式有很大的区另。
图 1为 3GPP移动通信网络架构示意图。 如图 1所示, 无线接入网 (如 通用陆地无线接入网 (UTRAN ) , 演进的 UTRAN ( E-UTRAN ) )和核心 网, 如在演进分组业务核心网 (EPC, Evolved Packet Core )中设有移动性管 理实体( MME, Mobility Management Entity ) ,月良务网关( Serving Gateway ) , 公共数据网关 (PDN Gateway )等网元, 在 GPRS核心网中包括服务通用分 组无线服务技术(GPRS ) 支持节点 (SGSN, Serving GPRS Support Node ) 等网元; 在 E-UTRAN中包括演进的节点 B ( eNB, evolved Node B ) ; 其中 E-UTRAN通过 SI接口和 EPC中的 MME/S-GW连接, UTRAN通过 Iu接口 和 SGSN连接。
寻呼(page )是为了向目标用户设备 ( UE )指示被叫信息请求或系统信 息更改, 收到寻呼消息的目标 UE根据寻呼消息指示与网络侧建立连接或者 读取更改的系统信息。 寻呼的范围一般是 UE的注册区域, 寻呼一般在特定 的时刻发送, 所述特定时刻通过 UE标识和寻呼周期计算获得, 因此每个 UE 都有对应的寻呼时刻。 空闲态或连接态, UE在自己的寻呼时刻监听寻呼。 寻呼过程由网络侧 MME/SGSN发起, 通过 E-UTRAN/UTRAN发送到目标 UE所在寻呼区域, 目标 UE在寻呼时刻接收相应的寻呼消息。
对于电池供电的 MTC UE, 需要釆取措施以降低 UE功耗。 对于有电源 供电的 MTC UE, 同样需要降低 UE功耗, 以实现绿色节能的目标。
目前, 智能手机逐渐普及, 同时出现了大量的应用业务运行在智能手机 上。 这些应用业务可能造成智能手机电池的功耗增加, 从而导致电池寿命缩 短。 因此智能手机的节电也是一个亟待解决的关键问题。
非连续接收(DRX, Discontinuous Reception )是一种减少 UE功耗的技 术,处于 DRX休眠状态的 UE关闭大部分的收发电路,从而达到节能的目的。 DRX可以应用在无线资源控制连接 ( RRC Connected, 以下简称连接)模式 和无线资源控制空闲(RRC Idle,以下简称空闲)模式,其中空闲模式的 DRX 即为寻呼 DRX。
为了进一步减少 UE的功耗,现有研究中提出了利用扩展的 DRX周期的 方案, 如釆用扩展的 DRX寻呼周期以减少空闲模式 UE的功耗。
在对相关技术的研究和实践过程中发现现有技术存在以下问题: 目前 UE在确定寻呼周期时, 根据上层指示和系统信息广播的寻呼周期 选择最小值。 因此即使网络侧 MME/SGSN釆用扩展的寻呼周期, UE仍釆用 系统信息中较短的缺省寻呼周期, 从而失去了釆用扩展 DRX寻呼周期的意 义。

步骤 S302, MME/SGSN收到请求消息后, 判断是否接受 UE所请求的 扩展寻呼周期请求, 如果是, 则转向步骤 S303 , 否则转向步骤 S304。
本申请的该实施例中, 所述 MME/SGSN根据 UE的签约信息和本地策 略判断是否接受 UE的请求, 例如 UE签约信息不支持请求的扩展寻呼周期, 和 /或在 MME/SGSN不支持扩展寻呼周期, 则 MME/SGSN拒绝 UE请求的 扩展寻呼周期。 步骤 S303 , MME/SGSN向 UE发送接受扩展寻呼周期请求的协商应答 指示信息。
