Description

用于短消息传输的方法和装置
技术领域
本发明涉及移动通信系统,尤其涉及一种用于短消息传输的方法 和装置。 背景技术
目前正在使用的第三代合作伙伴计划 (3GPP : The Third
Generation Partnership Project) 网络是第二代通信系统和第三代通信 系统, S卩: 通用分组无线服务技术 (GPRS : General Packet Radio Service ) 网络和通用移动通信系统 (UMTS : Universal Mobile Telecommunications System) 网络。
为了应对无线宽带技术的挑战, 保持第三代合作伙伴计划
( 3GPP: The Third Generation Partnership Project ) 网络的领先优势, 在 2004年底制定了 3GPP 网络的长期演进计划 (LTE: Long Term Evolution ) o 该长期演进计划定义了新的移动通信系统架构, 其与现 有 3GPP网络(即第二代通信系统和第三代通信系统)相比更加扁平, 并且只保留了分组交换域的功能。 因此, 该新的移动通信系统也称为 演进的分组网络 (EPS: Evolved Packet System )0
图 1示出了 EPS的示意图。 如图 1所示, EPS包括演进的通用 地面无线接入 网 ( EUTRAN : Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network) 禾口演进 的分组域核心网 (EPC: Evolved Packet Core)两个部分。 其中, EPC 主要包括移动管理实体(MME: Mobile Management Entity )、 服务网 关(S-GW: Serving Gateway)和公用数据网网关(P-GW: Public Data Network Gateway)这三个功能实体。其中, MME负责用户设备(UE: User Equipment) 的移动性管理(比如漫游、 切换等), 其功能对应于 现有 3GPP网络中的通用分组无线服务服务支持节点(SGSN: Serving General Packet Radio Service Support Node) 的控制平面部分。 S-GW 负责本地的移动性锚点和现有 3GPP网络的移动性锚点以及合法监听 相关信息。 P-GW则负责策略执行和计费以及合法监听相关功能。
通常,用户所使用的通信业务包括分组交换域的业务和电路交换 域 (CS: Circuit Switch) 的业务 (例如语音呼叫和短消息), 但 EPS 只能提供分组交换域的业务, 如果只通过 EPS向用户提供通信服务, 则不能覆盖用户的所有通信业务。 为此, 提出了集成现有 3GPP网络 和 EPS的通信系统, 以向用户提供全面的通信业务。
图 2示出了一种现有的集成现有 3GPP网络和 EPS的移动通信系 统的示意图。在图 2所示的移动通信系统中, EPS的 MME通过 SGs 接口连接到现有 3GPP网络的移动交换中心(MSC: Mobile Switching Center )。
按照图 2所示的移动通信系统, 当接入在 EPS的用户设备(UE: User Equipment) 想发起 CS的始呼 (MO: Mobile Originating) 业务 时, UE需要先接入到现有 3GPP网络, 才能进行该 MO业务。 当现 有 3GPP网络的 MSC收到一个针对 UE的 CS的终呼 (MT: Mobile Terminated) 业务时, MSC通过 SGs接口向 EPS的 MME发送寻呼 消息, MME通过 EPS的 EUTRAN对 UE进行寻呼, UE收到该寻呼 消息后, 需要先转到现有 3GPP网络, 然后才能完成该 MT业务的后 续处理。 因此, 图 2所示的通信系统向用户提供 CS业务的方法也称 为 "电路交换域回落 (CS fallback ) "。 虽然用户通过图 2所示的网络 架构可以使用 CS业务, 但是用户需要接入现有 3GPP网络, 这对用 户非常不便捷。
图 3示出了另一种现有的集成现有 3GPP网络和 EPS的移动通信 系统的示意图。 图 3所示的移动通信系统是针对 EPS的空闲模式信 令减少 (ISR: Idle-mode Signaling Reduction) 需求而提出的。 在图 3 所示的通信系统中, UE需要在现有 3GPP网络和 EPS都注册,即 UE 需要接入现有 3GPP网络和 EPS。 从而, 当 UE处于空闲模式时, 如 果 UE在这两个网络之间移动, 则不会不触发接入网移动性 (Inter 3GPP Access System Mobility) 流程, 从而减少空闲模式信令。 如图 3所示,在移动通信系统中部署了支持短消息转发的功能模 块 SMS-IWF, 其集成在 EPS中的 MME中。 当 UE附着在通信系统 时, UE只需要执行分组域附着, 即 UE只附着在 EPS的 MME上, 并且 EPS的归属签约用户服务器(HSS: Home Subscriber Server)把 UE所附着的 MME及其 SMS-IWF分别登记为向 UE提供服务的设备 和向 UE提供短消息转发服务的设备。
按照图 3所示的移动通信系统, 当一个 UE有短消息要发送给其 它 UE时, 该 UE通过 EPS的非接入层 (NAS: Non- Access Stratum) 消息把所要发送的短消息发送给 MME, 然后 MME通过 SMS-IWF 把所接收到的短消息发送短消息系统。当短消息系统有短消息要发送 给 UE时, 短消息系统查询 HSS获取向 UE提供短消息转发服务的 SMS-IWF,然后把要发送给 UE的短消息发送给所获取的 SMS-IWF, 接着由集成了 SMS-IWF的 MME通过 NAS消息把短消息发送给 UE。
然而, 在图 3所示的移动通信系统中, 如果 UE当前仅处在现有 3GPP网络而没有处在 EPS, 则 UE既不能向短消息系统发送短消息 也不能从短消息系统接收短消息, 因为 SMS-IWF与现有 3GPP网络 中的实体不存在任何逻辑和物理的接口。 发明内容
考虑到现有技术的上述问题,本发明的实施例提供一种用于短消 息传输的方法和装置, 利用该方法和装置, 在集成现有 3GPP网络和 EPS的移动通信系统中, 不管 UE是处在现有 3GPP网络还是 EPS, 都可以在 UE和短消息系统之间便捷地传输短消息。

按照本发明实施例所提出的用于短消息传输的方案,在集成现有 3GPP网络和 EPS的移动通信系统中, 使用现有 3GPP网络的 SGSN 来在 UE 和短消息系统 (例如短消息业务网关移动交换中心 (SMS-GMSC)、 短消息服务中心 (SMS-SC) 等) 之间转发短消息。 由于 SGSN可以通过现有 3GPP网络的接入网(例如通用地面无线接 入网 (UTRAN)、 GSM/EDGE无线接入网 (GERAN) ) 与 UE通信, 并且与 EPS的 MME存在 SGs接口可以与 MME通信, 因此, 当 UE 处在 3GPP网络时, SGSN可以通过现有 3GPP网络的接入网在 UE 和短消息系统之间转发短消息, 而当 UE处在 EPS时, SGSN可以通 过 EPS的 MME在 UE和短消息系统之间转发短消息, 从而, 不管 UE是处在现有 3GPP网络还是 EPS, 在 UE和短消息系统之间都可 以便捷地传输短消息,而且当 UE处在 EPS时, UE不需要接入 3GPP 网络就能接收和发送短消息。 下面, 将结合附图详细描述本发明的各个实施例。 现在参见图 4, 其示出了按照本发明一个实施例的用于短消息传 输的方法的流程图。
如图 4所示, 在步骤 S410, 当任何 UE 10想接入 EPS时, 用户 设备 10向 EPS的 EUTRAN发送用于请求接入 EPS的接入请求消息。 其中,接入请求消息携带有 UE 10的电路域业务只有短消息业务的指 示信息和 UE 10的标识, 例如该指示信息可以包括仅短消息 (SMS Only) 指示信元。 这里, 接入请求消息可以是附着请求消息 (Attach Request ) 或跟踪区更新请求消息 ( Tracking Area Update Request )。
本领域技术人员应当理解, 面对用户设备 10 的接入请求, EPS 分配一个移动管理实体 (MME: Mobile Management Entity) 来服务 用户设备 10, 这里将分配用于服务用户设备 10的 MME称为 MME 20。
在步骤 S414, 在接收到来自 UE 10的携带有 UE 10的电路域业 务只有短消息业务的指示信息的接入请求消息后, MME 20 从现有 3GPP 网络的 SGSN 中选择用于向 UE 10 提供短消息转发服务的 SGSN 30。本领域技术人员应当理解,针对不同的 UE所选择的 SGSN 既可能是同一个 SGSN, 也可能是不同的 SGSN。
其中, MME 20可以按照以下不同的方法来选择 SGSN 30。
MME 20可以根据 UE 10的位置选择用于向 UE 10提供短消息转 发服务的 SGSN 30。 具体的, 在接收到来自 UE 10的携带有 UE 10 的电路域业务只有短消息业务的指示信息的接入请求消息后, MME 20首先从其上所配置的跟踪区域(TA: Track Area)与路由区域(RA: Routing Area) 的绑定关系中, 检索出与在 UE 10接入 EPS的附着流 程或跟踪区更新流程中 EPS的演进的基站(eNodeB: Evolved NodeB ) 所携带的 TA 绑定的 RA, 然后向域名系统 (DNS: Domain Name System) 服务器查询与所检索的 RA对应的 SGSN, 最后选择所查询 的 SGSN作为用于向 UE 10提供短消息转发服务的 SGSN 30。
或者, MME 20可以选择上一次 UE 10接入现有 3GPP网络或 EPS时现有 3GPP网络中用于服务 UE 10的 SGSN作为向 UE 10提供 短消息转发服务的 SGSN 30。
或者, 如果 UE 10是双注册的 (即 UE 10可以同时注册到 EPS 和现有 3GPP网络)并且当前已经注册在现有 3GPP网络中,则 MME 20可以选择现有 3GPP网络中为 UE 10建立 ISR关联的 SGSN作为 用于向 UE 10提供短消息转发服务的 SGSN 30。
或者,如果 MME 20是 MME和 SGSN合一的融合节点,则 MME 20可以选择与其合一的 SGSN作为用于向 UE 10提供短消息转发 服务的 SGSN 30。
或者, MME 20可以按照路由路径最短的原则或随机地选择用 于向 UE 10提供短消息转发服务的 SGSN 30。
在步骤 S418, MME 20向所选择的用于向 UE 10提供短消息转 发服务的 SGSN 30发送更新位置请求 (Update Location Request) 消 息, 以指示 SGSN 30向 UE 10提供短消息转发服务。 其中, 该更新 位置请求消息可以包括 UE 10的标识与 MME 20的地址。
在步骤 S422, 在接收到来自 MME 20的用于指示 SGSN 30向 UE 10提供短消息转发服务的更新位置请求消息后, SGSN 30与 MME 20建立 SGs会话连接, 并且存储 UE 10的标识与 MME 20的地址的 映射关系。 其中, MME 20是在 EPS中服务 UE 10的 MME。
在步骤 S424, SGSN 30向 EPS中的归属签约用户服务器(HSS: Home Subscriber Server) 40发送更新位置请求消息, 以指示 HSS 40 将 SGSN 30登记为用于向 UE 10提供短消息转发服务的装置。其中, 该更新位置请求消息可以包括 UE 10的标识与 SGSN 30的地址。
在步骤 S426, SGSN 30向 MME 20发送更新位置响应消息, 以 告知 MME 20已经将 SGSN 30登记为用于向 UE 10提供短消息转发 服务的装置。
在步骤 S430,在接收到来自 SGSN 30的更新位置响应消息之后, MME 20存储 UE 10的标识与 SGSN 30的地址的映射关系。 在步骤 S434, 在接收到来自 SGSN 30 的用于指示 HSS 40将 SGSN 30登记为用于向 UE 10提供短消息转发服务的装置的更新位 置请求消息后, HSS 40存储 SGSN 30的地址与 UE 10的标识的映射 关系, 以将 SGSN 30登记为用于向 UE 10提供短消息转发服务的装 直。 在步骤 S438, 如果 UE 10想发送短消息给其它 UE, 则 UE 10 把封装有要发送给其它 UE的短消息的 EPS的 NAS消息发送给 MME 20。 其中, 封装有要发送给其它 UE 的短消息的 NAS 消息可以是 Uplink Generic NAS Transport消息。
在步骤 S442, 在接收到来自 UE 10的封装有要发送给其它 UE 的短消息的 NAS消息后, MME 20根据 UE 10的标识从所存储的映 射关系中, 检索出用于向 UE 10提供短消息转发服务的装置的地址。 如前所描述的, SGSN 30被选择用于向 UE 10提供短消息转发服务, 因此, 所检索的地址是 SGSN 30的地址。
在步骤 S446, MME 20根据所检索的 SGSN 30的地址, 通过与 SGSN 30所建立的 SGs会话连接,把所接收的要发送给其它 UE的短 消息发送给 SGSN 30。
在步骤 S450, 在接收到来自 MME 20的短消息后, SGSN 30把 所接收的短消息发送给短消息系统 50, 以便短消息系统 50把该短消 息发送给指定的 UE。 在步骤 S454,如果短消息系统 50接收到一个要发送给 UE 10的 短消息, 则短消息系统 50向 HSS 40发送一个查询请求消息, 以请求 查找用于向 UE 10提供短消息转发服务的装置的地址。其中, 该查询 请求消息可以包括 UE 10的标识。
在步骤 S458, 在接收到来自短消息系统 50的查询请求消息后, HSS 40根据 UE 10的标识, 从所存储的映射关系中, 查找出被登记 为用于向 UE 10提供短消息转发服务的装置的地址。 如前所描述的, SGSN 30被 HSS 40登记为用于向 UE 10提供短消息转发服务的装置, 因此, 所查找的地址是 SGSN 30的地址。
在步骤 S462, HSS 40向短消息系统 50发送一个查询响应消息, 其中该查询响应消息包括 SGSN 30的地址。
在步骤 S466, 在接收到来自 HSS 40的查询响应消息后, 短消息 系统 50根据所接收的查询响应消息所包括的 SGSN 30的地址, 把所 接收的要发送给 UE 10的短消息发送给 SGSN 30。其中,该短消息可 以包括 UE 10的标识。
在步骤 S470,在接收到来自短消息系统 50的要发送给 UE 10的 短消息后, SGSN 30根据 UE 10的标识, 从所存储的映射关系中, 检 索出在 EPS中服务 UE 10的装置的地址。 如前所描述的, 在 EPS中 服务 UE 10的 MME是 MME 20, 因此, 所检索的地址是 MME 20的 地址。
在步骤 S474, SGSN 30根据所检索的 MME 20的地址, 通过与 MME 20所建立的 SGs会话连接,把所接收的要发送给 UE 10的短消 息发送给所检索的 MME 20。
在步骤 S478, 在接收到来自 SGSN 30的要发送给 UE 10的短消 息后, MME 20把要发送给 UE 10的短消息封装在 NAS消息中。 其 中, 该 NAS消息可以是 Downlink Generic NAS Transport消息。
在步骤 S482, MME 20向 UE 10发送封装有要发送给 UE 10的 短消息的 NAS消息。
如果封装有要发送给 UE 10的短消息的 NAS消息被成功发送给 UE 10, 则流程结束。
在步骤 S486,如果封装有要发送给 UE 10的短消息的 NAS消息 没有被成功发送给 UE 10, 则 MME 20向 SGSN 30发送用于表示通 过 EPS发送要发送给 UE 10的短消息失败的消息。 在步骤 S490, 在接收到来自 MME 20的用于表示通过 EPS发送 要发送给 UE 10的短消息失败的消息后, SGSN 30通过现有 3GPP网 络的接入网向 UE 10发送要发送给 UE 10的短消息。这里,由于 SGSN 30通过现有 3GPP网络发送短消息是已知的, 因此, 对此不再赘述。
本领域技术人员应当理解, 虽然在上面实施例的步骤 S418中, MME 20存储 UE 10的标识与所选择的用于向 UE 10提供短消息转发 服务的 SGSN 30的地址的映射关系, 然而, 本发明并不局限于此。
在本发明的其它一些实施例中, MME 20也可以不存储 UE 10的 标识与所选择的用于向 UE 10提供短消息转发服务的 SGSN 30的地 址的映射关系。 在这种情况下, 由于 HSS 40已经存储有 UE 10的标 识与所选择的用于向 UE 10提供短消息转发服务的 SGSN 30的地址 的映射关系,因此当需要了解是哪一个 SGSN用于向 UE 10提供短消 息转发服务时, MME 20可以向 HSS 40发送查询请求消息, 以请求 HSS 40查找用于向 UE 10提供短消息转发服务的 SGSN的地址。 响 应于该查询请求消息, HSS 40根据 UE10的标识, 从所存储的映射 关系中,查找出被登记为用于向 UE 10提供短消息转发服务的 SGSN 的地址,然后向 MME 20返回包含所查找的地址的查询响应消息。采 用这种方式, 可以减少占用 MME 20的存储空间。
本领域技术人员应当理解, 虽然在上面实施例的步骤 S426中, UE 10的标识与在 EPS中服务 UE 10的 MME 20的地址的映射关系 存储在 SGSN 30中, 然而, 本发明并不局限于此。
在本发明的其它一些实施例中, UE 10的标识与在 EPS中服务 UE 10的 MME 20的地址的映射关系也可以不存储在 SGSN 30中, 而是存储在 HSS 40中。 具体地, 在接收到来自 MME 20的用于指示 SGSN 30 向 UE 10 提供短消息转发服务的更新位置请求消息后, SGSN 30把 UE 10的标识与在 EPS中服务 UE 10的 MME 20的地址 的映射关系发送给 HSS 40, HSS 40存储来自 SGSN 30的 UE 10的标 识与在 EPS中服务 UE 10的 MME 20的地址的映射关系。 当需要了 解在 EPS中服务 UE 10的 MME的地址时, SGSN 30可以向 HSS 40 发送查询请求消息,以请求 HSS 40查询在 EPS中服务 UE 10的 MME 的地址。 响应于该查询请求消息, HSS 40根据 UE 10的标识, 从所 存储的映射关系中, 查询在 EPS中服务 UE 10的 MME的地址, 然 后向 SGSN 30返回包含所查找的地址的查询响应消息。 采用这种方 式, 可以减少占用 SGSN 30的存储空间。
本领域技术人员应当理解, 在上面实施例的步骤 S482 中, 当 MME 20向 UE 10发送封装有要发送给 UE 10的短消息的 NAS消息 时, 如果 UE 10处于空闲状态, 则 MME 20首先寻呼 UE 10, 并在寻 呼到 UE 10后, 才向 UE 10发送封装有要发送给 UE 10的短消息的 NAS消息。 如果寻呼不到 UE 10, 则不能通过 EPS向 UE 10发送要 发送给 UE 10的短消息, 从而 MME 20向 SGSN 30发送用于表示通 过 EPS发送要发送给 UE 10的短消息失败的消息。
其中, 在 MME 20寻呼 UE 10的过程中, 如果 UE 10是双注册 的, 即 UE 10同时接入到 EPS和现有 3GPP网络, 则 MME 20除了 在 EPS中寻呼 UE 10之外, 还要通知现有 3GPP网络中为 UE 10建 立 ISR关联的 SGSN在现有 3GPP网络中寻呼 UE 10。如果在步骤 S314 中,现有 3GPP网络中为 UE 10建立 ISR关联的 SGSN被选择为用于 向 UE 10提供短消息转发服务的 SGSN,则现有 3GPP网络中为 UE 10 建立 ISR关联的 SGSN与用于向 UE 10提供短消息转发服务的 SGSN 是同一个 SGSN。
本领域技术人员应当理解,虽然在上面实施例中, UE 10和 MME 20之间通过 NAS消息来传递短消息, 然而, 本发明并不局限于此。 在本发明的其它一些实施例中, UE 10和 MME 20之间也可以通过除 了 NAS消息之外的其它消息来传递短消息, 或者可以不借助任何消 息直接传递短消息。
本领域技术人员应当理解, 虽然在上面实施例的步骤 S422中, MME 20通过更新位置请求消息来指示 SGSN 30向 UE 10提供短消 息转发服务, 然而, 本发明并不局限于此。在本发明的其它一些实施 例中, MME 20也可以通过其它的消息或者直接地指示 SGSN 30向 UE 10提供短消息转发服务。
本领域技术人员应当理解, 虽然在上面实施例的步骤 S430中, SGSN 30通过更新位置请求消息来指示 HSS 40将 SGSN 30登记为用 于向 UE 10提供短消息转发服务的装置,然而,本发明并不局限于此。 在本发明的其它一些实施例中, SGSN 30也可以通过其它的消息或者 直接地指示 HSS 40将 SGSN 30登记为用于向 UE 10提供短消息转发 服务的装置。
本领域技术人员应当理解, 虽然在上面实施例的步骤 S414中, 当接入请求消息中携带有 UE 10的电路域业务只有短消息业务的指 示信息时, MME 20 才选择用于向 UE 10 提供短消息转发服务的 SGSN, 然而, 本发明并不局限于此。在本发明的其它一些实施例中, 在接收到来自 UE 10的接入请求消息,即使接入请求消息并没有携带 有 UE 10的电路域业务只有短消息业务的指示信息, MME 20也可以 选择用于向 UE 10提供短消息转发服务的 SGSN。
本领域技术人员应当理解, 虽然在上面实施例中, SGSN 30 与 MME 20建立 SGs会话连接, 并且 SGSN 30和 MME 20通过所建立 的 SGs 会话连接来传输短消息, 然而, 本发明并不局限于此。 在本 发明的其它一些实施例中, SGSN 30与 MME 20也可以不建立 SGs 会话连接, 这种情况下, SGSN 30和 MME 20通过其它方式来传输 短消息。 现在参考图 5, 其示出了按照本发明一个实施例的用于短消息传 输的装置的示意图。本领域技术人员应当理解, 图 5所示的装置可以 安装在 EPS的 MME中,并且可以利用软件、硬件或软硬件结合的方 式来实现。
