Description

一种通讯方法、 基站及无线接入点
技术领域
本发明涉及通信技术领域, 具体涉及一种通讯方法、 基站及无线接入点。 背景技术
随着移动通信系统的发展, 系统能够提供的传输速率和服务质量越来越 高, 用户业务对传输速率的要求也越来越高, 为了在不大幅增加配置带宽的 情况下, 保证一般用户的传输速率, 同时为一部分用户提供更高的吞吐量, 3GPP引入了载波聚合 (Carrier Aggregation , CA) 技术, 所谓载波聚合是用户 设备 (User Equipment, UE) 可以同时使用多个成员载波 ( Component Carrier , CC) 进行上下行通信, 从而支持高速数据传输。 当用户速率降低时, 可以释 放一些成员载波, 只保留一个驻留载波, 释放出来的传输资源可以供其它用 户使用, 从而达到灵活、 动态的目的。
目前的载波聚合只能实现同一系统的多个成员载波的聚合, 即一个 UE 使用的成员载波均为同一系统内的载波, 例如都属于 LTE ( Long Term Evolution,长期演进)、或者都属于 UMTS (Universal Mobile Telecommunications System , 通用移动通信系统)、 或都属于 WiFi (Wireless Fidelity, 无线保真)。 在这种载波聚合中, 多个成员载波属于同一系统, 同一调度器, 就能实现底 层动态共享, 例如同一业务的第 n个包通过一个成员载波发送, 第 n+1个包 则通过另一个成员载波发送。 这种聚合方式虽能实现资源共享, 提高通信系 统性能, 但却未考虑各个系统具有的优劣势, 进而也就不能充分利用不同系 统的优势, 实现提高通信系统性能和吞吐量的目的。 发明内容

为了使本技术领域的人员更好地理解本发明实施例的方案, 下面结合附 图和实施方式对本发明实施例作进一步的详细说明。
本发明实施例的通讯方法、 基站及无线接入点, 适用于不同系统聚合形 成的通信系统, 本文主要介绍由 LTE和 WiFi聚合而成的通信系统, 但并不 仅仅局限于由上述 LTE和 WiFi聚合而成的系统。 在介绍本发明实施例的具 体技术方案之前, 下面先对 LTE和 WiFi聚合而成的通信系统进行简单介绍。
LTE系统具有覆盖范围广、 支持高速移动等优点, 同时具有数据速率低、 价格高、 传输功率大等缺点, 比较适合于高速运动、 室外大范围活动等场景; WiFi系统具有数据速率高、 价格低、 传输功率小等优点, 同时具有覆盖范围 小、 AP (Wireless Access Point, 无线访问接入点) 间切换时丟包率高等缺点, 比较适合于相对静止、 室内小范围活动等场景。 考虑到 LTE 系统和 WiFi 系 统各自的优缺点之后, 可聚合这两种系统, 将二者有机结合, 充分发挥二者 的优点,实现高效低成本的通信过程。参见图 1,示出了一种 LTE系统与 WiFi 系统聚合的结构示意图, 其中 AP30作为 WiFi系统的接入桥梁, 可直接接入 到 LTE 系统的基站 20, 基站接收 LTE 接入网络的移动性管理实体 MME (Mobility Management Entity) 10下发的 PDNs (Public Data NetWorks , 公用 数据网) 数据, 并将数据通过 WiFi AP下发给用户设备 UE40。 相对于单纯的 LTE系统或者单纯的 WiFi系统来说,将两种系统有机结合之后就能显著提高 整个通信系统的性能和吞吐量, 实现高效低成本通信。
构建形成图 1 所示的聚合系统之后, 最为关键的一个问题即是当 UE进 入 WiFi系统的覆盖范围, 且有下行数据到达时, 如何使 UE与 WiFi AP建立 数据连接, 为此本发明实施例提供了如下的通讯方法。 参见图 2, 示出了本发明实施例通讯方法实施例 1的流程图, 包括: 步骤 101, 基站接收移动性管理实体发送的指示消息; 所述指示消息包括 位于无线接入点的用户设备的媒体接入控制地址, 该指示消息用于指示所述 基站通过所述无线接入点寻呼所述用户设备。
当移动性管理实体 MME接收到服务网关 Serving GW下发的下行数据通 知消息后, 即会向基站发送上述用于寻呼用户设备的指示消息。 一般情况下, 指示消息可以体现为寻呼消息, 为了使无线接入点 AP 能够准确与用户设备 建立通讯, 指示消息中应包含用户设备的 MAC ( Media Access Control, 媒体 接入控制) 地址。
因为 MME下发的指示消息是一种 LTE消息, 为了使 WiFi系统中的 AP 正确解析识别出指示消息的内容, 基站需要按照 AP 协议栈的要求重新封装 其接收到的指示消息, 即将 LTE的指示消息封装成 WiFi帧结构。
根据 LTE系统和 WiFi系统聚合的协议层的不同, 封装后的指示消息也 有所不同。例如,如果 LTE系统和 WiFi系统聚合在 RLC (Radio Link Control, 无线链路控制层协议) 层, 则封装后的指示消息为基站生成的 RLC PDU ; 如 果 LTE系统和 WiFi系统聚合在 PDCP (Packet Data Convergence Protocol, 分 组数据汇聚协议) 层, 则封装后的指示消息为基站生成的 PDCP PDU。
需要说明的是,对于包含在指示消息中的用户设备的 MAC地址来说,其 可以是具有 LTE和 WLAN聚合能力的用户设备自行上报给 LTE网络的, 具 体的, 用户设备可以在开机后通过附着请求 (Attach Request) 携带给 MME , 也可以在用户设备与核心网做同步时通过跟踪区更新请求 (Tracking Area Update Request) 携带给 MME , 本发明对此不做限定。 MME在接收到用户设 备的 MAC地址后, 可将其作为该用户设备上下文的一部分保存在 MME中, 以备在需要时将其添加到指示消息中下发给基站。
步骤 102,所述基站向所述无线接入点发送所述指示消息, 以使所述无线 接入点根据所述媒体接入控制地址与所述用户设备进行通讯。
AP在接收到基站下发的封装后的指示消息之后, 才艮据用户设备的 MAC 地址生成相应的数据包,例如, 将用户设备的 MAC地址添加到 WiFi的帧头, 然后将数据包下发给指定用户设备, 即具有上述 MAC地址的用户设备。
在本方法实施例中,无线接入点与用户设备之间进行的是点对点的寻呼, 因此 MME下发给基站的指示消息中应该包括用户设备的 MAC地址,这样基 站才能通过 AP将生成的数据包下发给指定用户设备, 使 AP与指定用户设 备建立数据连接。 需要说明的是, 为了实现点对点的寻呼, 用户设备还要通 过检测 MAC地址的方式判断 AP下发的数据包是否针对自己,如果用户设备 自身的 MAC地址与 AP下发的 MAC地址相匹配, 用户设备才会接收 AP下 发的数据包, 进而与 AP建立数据连接, 利用图 1 所示的载波聚合系统进行 高效低成本通信。 与上述通讯方法实施例 1相对应的, 本发明实施例还提供了一种通讯系 统实施例 1, 包括基站、 移动性管理实体 MME、 无线访问接入点 AP和用户 设备 UE,其中基站和 MME属于 LTE系统, AP属于 WLAN系统,且 MME 保存有 UE的 MAC地址。 下面以寻呼消息作为指示消息为例, 结合图 3所示 的信令交互示意图, 对上述各个部分所起作用以及各部分间的信息交互过程 进行简单介绍。
步骤 201,具有 LTE与 WALN聚合能力的 UE上报其 MAC地址给网络, MME接收到该 UE的 MAC地址后,将其作为 UE上下文的一部分保存在 MME 中。
步骤 202, 当 MME接收到 Serving GW下发的 Downlink Data Notification 消息后,下发 paging消息给相关基站。如果 MME保存了该 UE的 MAC地址, 则 MME向基站下的发寻呼消息中还包含该 UE的 MAC地址。
步骤 203, 基站按照 AP协议栈封装寻呼消息, 并将封装后的寻呼消息发 送给 AP (如果没有特殊说明, 此处的 AP是指 WLAN系统中所有的 AP)。
步骤 204, AP才艮据寻呼消息中的 MAC地址生成相应的数据包, 即将 UE 的 MAC地址添加到 WLAN的帧头, 并将数据包下发给 UE。
步骤 205,UE通过检测 AP下发的 MAC地址的方式来判断其是否要接收 数据包, 如果 UE 自身的 MAC地址与 AP下发的 MAC地址相同, 则认为数 据包是针对自己发送的, 应接收该数据包。
需要说明的是, 上述图 2和 3所示的实施例 1中, AP接收到指示消息之 后, 可以直接将指示消息转发给具有基站下发的 MAC地址的 UE , 无需识别 基站发送指示消息的意图, 也就是说, 基站可以只向 AP 下发指示消息, 无 需关注 AP是否能识别。 当然, 为了使 AP知晓本次通讯行为的意图, 在基站 向 AP下发指示消息的同时,还可通过一定的手段使 AP知晓其当前接收到的 是一个指示消息。 对于使 AP识别指示消息的技术手段, 将在后续展开描述, 此处暂不详述。 参见图 4, 示出了本发明实施例通讯方法实施例 2的流程图, 包括: 步骤 301, 基站接收移动性管理实体发送的指示消息; 所述指示消息包括 位于无线接入点的用户设备的媒体接入控制地址以及所述用户设备的专属无 线接入点标识, 所述指示消息用于指示所述基站通过所述无线接入点寻呼所 述用户设备。
步骤 302, 所述基站才艮据所述用户设备的专属无线接入点标识,确定发送 所述指示消息的所述无线接入点。
步骤 303,所述无线接入点根据所述媒体接入控制地址与所述用户设备进 行通讯。
与方法实施例 1 相比, 本实施例在实现无线接入点 AP 与用户设备之间 的点对点寻呼之外, 还进一步地将与用户设备建立数据连接的 AP 限定为私 有 AP。 所谓私有 AP是指只允许部分签约用户设备接入的 AP, 即并不是所 有位于私有 AP的用户设备都可接入该私有 AP。 本实施例中, 通过建立 UE 与私有 AP间的数据连接, 就能避免基站向所有 AP都广播指示消息, 节约空 口资源。
具体地, 作为步骤 302确定私有 AP的一种实现方式, 可以体现为: 基站 才艮据所述无线接入点的服务集标识及所述用户设备的专属无线接入点标识的 映射关系, 确定发送所述指示消息的所述无线接入点。
作为服务集标识的一种实现方式可以为 SSID ( Service Set Identifier), 专 属无线接入点标识的一种实现方式可以为 CSG IDs ( Closed Subscriber Group Identifier), 二者——对应。 MME不仅要通过指示消息向基站发送用户设备的 MAC地址, 以此明确寻呼对象是谁; 还要向基站发送 CSG IDs , 以通过 CSG IDs与 AP SSID的映射关系明确用于寻呼用户设备的 AP是谁。 与上述通讯方法实施例 2相对应的, 本发明实施例还提供了一种通讯系 统实施例 2 ,与实施例 1不同的是,本实施例中的 MME还支持寻呼优化功能, 基站配置了 CSG IDs与 AP SSID间的——映射关系, AP为私有 AP。 下面结 合图 5所示的信令交互示意图, 对上述各个部分所起作用以及各部分间的信 息交互过程进行简单介绍。
步骤 401, 具有 LTE与 WiFi聚合能力的 UE上报其 MAC地址给网络, MME接收到该 UE的 MAC地址后,将其作为 UE上下文的一部分保存在 MME 中。
步骤 402, 当 MME接收到 Serving GW下发的下行数据通知消息后, 下 发 paging消息给相关基站, paging消息中包含 UE所属的 CSG IDs和 UE的 MAC地址。
步骤 403, 基站才艮据其配置的 CSG IDs与 APs的 SSID间的映射关系, 查 找寻呼消息中的 CSG IDs对应的 AP (此处的 AP是指私有 AP)。
步骤 404, 基站选择好 AP后, 按照 AP协议栈封装寻呼消息, 并将封装 后的寻呼消息和 UE的 MAC地址发送给选择的 AP。
步骤 405, 私有 AP将 UE的 MAC地址添加到 WiFi的帧头, 并将数据包 下发给指定 UE , 建立私有 AP与指定 UE间的数据连接。 参见图 6, 示出了本发明实施例通讯方法实施例 3的流程图, 包括: 步骤 501, 基站接收移动性管理实体发送的指示消息, 所述指示消息用于 指示所述基站通过无线接入点寻呼用户设备。
步骤 502, 所述基站向所述无线接入点发送所述指示消息, 以使所述无线 接入点根据公共媒体接入控制地址与位于所述无线接入点的用户设备进行通 讯。
与方法实施例 1 不同, 本实施例不是进行 AP 与用户设备间的点对点寻 呼, 而是采用广播方式向位于 AP 覆盖范围内的所有用户设备下发数据包, 因此 MME下发给基站的指示消息中无需包括用户设备的 MAC地址。对应于 本实施例, 用户设备接收到指示消息后, 也无需利用其具有的 MAC地址检测 AP 下发的数据包是否针对自己。 采用本实施例技术方案, 在用户设备与 AP 建立数据连接之后, 亦可利用图 1所示的载波聚合系统进行高效低成本通信。 与上述通讯方法实施例 3相对应的, 本发明实施例还提供了一种通讯 系统实施例 3, 与实施例 1 不同的是, MME无需保存用户设备的 MAC地 址。下面以寻呼消息作为指示消息为例,结合图 7所示的信令交互示意图, 对上述各个部分所起作用以及各部分间的信息交互过程进行简单介绍。
步骤 601, 当 MME接收到 Serving GW下发的下行数据通知消息后, 下 发 paging消息给相关基站。 需要说明的是, MME可以根据 UE所注册的位置 区信息来决定下发给哪些相关基站。
步骤 602, 基站按照 AP协议栈封装寻呼消息, 并将封装后的寻呼消息发 送给 AP (如果没有特殊指示, 此处的 AP是指 WLAN系统中所有的 AP)。
步骤 603, AP利用 UE的公共 MAC地址生成相应的数据包, 即将 UE的 公共 MAC地址添加到 WLAN的帧头, 并将该数据包广播给所有的 UE。
需要说明的是, 上述图 6和 7所示的实施例 3中,如果 AP的协议栈具有 识别指示消息的功能, 基站就可以直接将指示消息发送给 AP , 即由协议栈来 识别基站发送指示信息的意图; 如果 AP协议栈不具有识别指示消息的功能, 则基站在向 AP下发封装后的指示消息的同时,还应通过一定的手段使 AP知 晓其当前接收到的是一个指示消息。 下面对 AP 识别指示消息的实现手段进行简单介绍, 主要可体现为以下 两 中方式:
一种是, 设置一个指示消息标识, 在基站向 AP 下发封装后的指示消息 的同时, 还将指示消息标识下发给 AP , 以使 AP根据所述标识识别所述指示 消息, 即 AP根据该标识明确基站发送消息的意图是什么;
一种是, 在基站和 AP 之间定义承载指示消息的专用信令, 基站通过该 专用信令将封装后的指示消息发送给 AP, 以使 AP根据所述专用信令识别所 述指示消息, 即 AP通过专用信令的方式明确基站发送消息的意图是什么。 参见图 8, 示出了本发明实施例通讯方法实施例 4的流程图, 包括: 步骤 701, 基站接收移动性管理实体发送的指示消息, 所述指示消息包括 所述用户设备的专属无线接入点标识, 所述指示消息用于指示所述基站通过 无线接入点寻呼用户设备。
步骤 702, 所述基站才艮据所述用户设备的专属无线接入点标识,确定发送 所述指示消息的所述无线接入点。
步骤 703, 所述基站向所述无线接入点发送所述指示消息, 以使所述无线 接入点根据公共媒体接入控制地址与位于所述无线接入点的用户设备进行通 讯。
本实施例与方法实施例 3的设计思路相似, 均是向 WLAN系统覆盖范围 内的 UE广播寻呼消息,所不同的是, 实施例 3是通过 WiFi系统中的所有 AP 向 UE广播生成的数据包, 实施例 4则是通过指定的私有 AP进行数据广播, 这样可以避免基站覆盖下所有的 AP都广播寻呼消息, 节省资源。 因此 MME 下发给基站的指示消息中应该包括专属无线接入点标识, 以此来指定一个私 有 AP , 这样基站才能正确的将封装后的指示消息发送给指定的私有 AP , 进 而由私有 AP向可以访问该 AP的所有 UE广播封装后的寻呼消息, 所谓可以 访问该 AP的 UE是指该私有 AP的签约用户设备。
具体地, 作为步骤 702确定私有 AP的一种实现方式, 可以体现为: 基站 才艮据所述无线接入点的服务集标识及所述用户设备的专属无线接入点标识的 映射关系, 确定发送所述指示消息的所述无线接入点。
作为服务集标识的一种实现方式可以为 AP SSID , 专属无线接入点标识 的一种实现方式可以为 CSG IDs, 二者——对应。 MME要通过指示消息向基 站发送 CSG IDs, 以使基站通过 CSG IDs与 AP SSID的映射关系明确用于寻 呼用户设备的 AP是谁。 同样地, 与上述通讯方法实施例 4相对应的, 本发明实施例还提供了一 种通讯系统实施例 4, 与实施例 3不同的是, 本实施例中的 MME支持寻呼优 化功能, 基站配置了 CSG IDs与 APs的 SSID间的——映射关系, AP为私有 AP。 下面以寻呼消息作为指示消息为例, 结合图 9所示的信令交互示意图, 对上述各个部分所起作用以及各部分间的信息交互过程进行简单介绍。 步骤 801, 当 MME接收到 Serving GW下发的 Downlink Data Notification 消息后, 下发 paging消息给相关基站。 因为 MME支持寻呼优化功能, 因此 寻呼消息中应还包含 UE所属的 CSG IDs。
步骤 802, 基站才艮据其配置的 CSG IDs与 APs的 SSID间的映射关系, 查 找寻呼消息中的 CSG IDs对应的 AP (此处的 AP是指私有 AP)。
步骤 803, 基站选择好 AP后, 按照 AP协议栈封装寻呼消息, 并将封装 后的寻呼消息发送给选择的 AP。
步骤 804, 私有 AP将 UE的公共 MAC地址添加到 WiFi的帧头, 并将该 数据包广播给能接入到本私有 AP的所有 UE。 以上通讯方法的实施例 1-4 是从基站角度出发, 对本发明聚合系统的通 讯过程进行的解释说明。 需要说明的是, 当所述指示消息为寻呼消息时, 本 发明实施例中的用户设备于所述无线接入点中处于空闲状态。
一般情况下, 可以用户设备是否驻留在 LTE系统为依据, 确定用户设备 的当前状态, 如果用户设备驻留在 LTE 系统并与基站建立了 RRC (Radio Resource Control , 无线资源控制) 连接, 则为连接态, 否则为空闲态。 如果 用户设备以空闲态进入 WiFi系统的覆盖范围,且 MME接收到 Serving GW下 发的下行数据通知消息 (Downlink Data Notification message), 则会触发 MME 向基站下发指示消息, 利用本发明的技术方案, 指示基站通过 WiFi AP寻呼 用户设备, 形成图 1所示的载波聚合系统进行高效低成本通信。 下面再从无线接入点的角度出发, 对本发明实施例的通讯过程进行解释 说明。
参见图 10, 示出了本发明实施例通讯方法实施例 5的流程图, 包括: 步骤 901, 无线接入点接收基站发送的指示消息; 所述指示消息由移动性 管理实体向所述基站发送, 所述指示消息包括位于无线接入点的用户设备的 媒体接入控制地址, 所述指示消息用于指示所述无线接入点寻呼所述用户设 备。
步骤 902,所述无线接入点根据所述媒体接入控制地址与所述用户设备进 行通讯。
无线接入点 AP 接收基站发送的指示消息, 并在指示消息的作用下, 与 位于 AP覆盖范围内的指定用户设备建立数据连接, 以将 LTE系统下发的数 据通过 AP下发给用户设备, 充分利用 LTE和 WLAN两种系统的优势, 提高 聚合系统的性能和吞吐量, 实现高效低成本通信。
上述通讯方法实施例 5中, AP与用户设备之间进行的是点对点的寻呼, 且受指示消息作用寻呼用户设备的 AP是聚合的 WLAN系统包含的所有 AP , 为了避免浪费空口资源, 还可通过 WLAN系统中的指定 AP向用户设备下发 数据, 对应于此, 指示消息中还应包括所述用户设备的专属无线接入点标识, 这样, 基站就可以根据用户设备的专属无线接入点标识, 确定发送所述指示 消息的无线接入点。 相应地, 上述实施例 5 中的执行主体就是具有所述专属 无线接入点标识的私有 AP , 通过建立用户设备与私有 AP间的数据连接, 就 能避免基站向所有 AP都广播指示消息, 节约空口资源。
与上述实施例 1-4 相同的, 作为指示消息的一种实现方式, 其可以体现 为寻呼消息。 另外需要说明的是, 当所述指示消息为寻呼消息时, 所述用户 设备于所述无线接入点中处于空闲状态。 参见图 11, 示出了本发明实施例通讯方法实施例 6的流程图, 包括: 步骤 1001, 无线接入点接收基站发送的指示消息; 所述指示消息由移动 性管理实体向所述基站发送, 所述指示消息用于指示所述无线接入点寻呼所 述用户设备。
步骤 1002, 所述无线接入点根据公共媒体接入控制地址与位于所述无线 接入点的用户设备进行通讯。
与方法实施例 5 不同, 本实施例不是进行 AP 与用户设备之间的点对点 寻呼, 而是采用广播方式向位于 AP覆盖范围内的所有用户设备下发数据包, 对应于此, 用于指示 AP 寻呼用户设备的指示消息中也就无需包含用户设备 的 MAC地址, AP接收到指示消息之后, 即可直接利用其保存的用户设备的 公共 MAC地址, 向位于其覆盖范围内的所有用户设备进行数据广播。
同样地, 上述方法实施例 6 中, 受指示消息作用寻呼用户设备的 AP指 的是聚合的 WLAN 系统包含的所有 AP, 为了避免浪费空口资源, 还可通过 LAN 系统中的指定 AP向用户设备下发数据, 对应于此, 指示消息中应包 括所述用户设备的专属无线接入点标识, 这样, 基站就可以根据用户设备的 专属无线接入点标识, 确定发送所述指示消息的无线接入点。 相应地, 上述 实施例 6中的执行主体就是具有所述专属无线接入点标识的私有 AP ,通过建 立用户设备与私有 AP间的数据连接,就能避免基站向所有 AP都广播指示消 息, 节约空口资源。 如果用户设备驻留在 LTE系统,基站接收到 MME下发的指示消息之后, 即可通过指示消息指示用户设备到特定的 AP 下面建立数据连接, 加快用户 设备到 AP的驻留, 对应于此, 可参见图 12所示的通讯方法实施例 7的流程 图, 所述方法包括:
步骤 1101, 基站接收移动性管理实体下发的指示消息, 并判断用户设备 是否应与 WLAN建立数据连接。
步骤 1102, 如果判断结果为是, 基站则将指定无线接入点的服务集标识 添加到所述指示消息中发送给所述用户设备, 以使所述用户设备根据所述服 务集标识查找所述指定无线接入点,并与所述指定无线接入点建立数据连接。
本实施例中, 基站接收到指示消息后, 可直接通过指示消息来指示用户 设备到特定的 AP下面建立连接, 从而加快 UE到 AP的驻留过程。
在基站向用户设备下发指示之前, 应先判断用户设备当前是否应与 AP 建立连接。 例如, 判断用户设备是否进入 WiFi的覆盖范围, 如果未进入, 即 使基站向用户设备下发了指示, 用户设备也不能成功的与指定 AP建立连接; 如果用户设备已进入 WiFi的覆盖范围, 还可进一步判断基站是否需要分担负 载, 如果不需要, 则即使用户设备进入 WiFi覆盖范围亦没有建立用户设备与 AP间数据连接的必要。 由此可知, 只有在基站判定用户设备已进入 WiFi覆 盖范围, 且基站需要分担负载时, 才指示用户设备驻留到 AP , 这样, 才能提 高通信系统的吞吐量, 实现高效低成本通信。 与上述通讯方法实施例 7相对应的, 本发明实施例还提供了一种通讯系 统实施例 5, 与系统实施例 1-4不同的是, 本实施例中的基站具有自动判断功 能, 且用户设备能够识别 AP的服务集标识。 下面以寻呼消息作为指示消息 为例, 结合图 13所示的信令交互示意图,对上述各个部分所起作用以及各部 分间的信息交互过程进行简单介绍。
步骤 1201, 基站接收到 MME下发的 paging消息后, 先自动判断 UE是 否应与 WLAN建立数据连接, 如果判断结果表示 UE应在 WiFi下建立连接, 基站则在 Paging消息里添加 AP的服务集标识, 以此指示 UE到该 AP下建立 数据连接。
步骤 1202, UE根据服务集标识搜索对应的 AP , 并在搜索到的 AP下面 建立数据连接。 为了在有下行数据到达时, 及时通知用户设备与 AP 建立数据连接, 本 发明实施例还提供一种基于专用承载的方案。 用户设备进入到 WLAN AP的 覆盖范围内, 则与 AP建立连接, 并触发 AP与基站间与该用户设备相关的接 口建立, 之后通过 S1 口的建立使用户设备进入到连接态, 当数据到达时, 直 接建立专用承载, 将数据通过 AP下发给用户设备。 具体可参见图 14所示的 信令交互示意图, 通讯过程为:
步骤 1301, UE在 WiFi系统驻留。
本步骤可通过以下任一种方案实现:
UE自主选择 WLAN驻留。如 UE可根据 ANDSF( Access Network Discovery and Selection Functions, 接入网发现和选择功能单元, 提供了一种根据运营商 策略为终端选择目标接入网络的模式) 策略进行网络发现和选择, 当发现有 满足 ANDSF策略中预设条件的 WLAN网络, 选择并驻留到该 WLAN网络。
UE检测到 LTE无线链路失败。 如 UE在 LTE中失去连接, 或者检测不 到 LTE的覆盖, 或者 UE检测到 LTE的信号质量低于预设的门限值, UE则 启动对 WLAN网络的发现和选择, 驻留到合适的 WLAN网络中。
基站指示 UE在 WLAN系统驻留。 基站可才艮据网络负载情况, 下发切换 或者重定向消息指示 UE驻留到 WLAN网络中。
步骤 1302, UE在 WLAN成功驻留后, 按照现有的流程, UE的 WLAN 协议栈指示给 UE的 LTE协议栈, UE在 WLAN驻留成功。
步骤 1303, UE在 WLAN成功驻留后, UE通过业务请求(service request) 或!1付着请求 (Attach Request) 或位置区更新请求 (Tracking Area Update) 向 LAN系统中的 AP发起请求。
步骤 1304, 当 AP接收到 UE发送的请求后, 才艮据其保存的配置信息, 触发 AP和基站间与该 UE相关的接口建立。此处可通过为 UE分配不同 UE ID 的方式来标示 UE, 这样 AP就能通过 UE ID知晓其应触发哪个接口, 并将接 口编号添加到请求中发给基站。
步骤 1305, 基站接收到 AP 发送的请求, 即检测到存在一个 NAS (Non- Access Stratum , 非接入层) 消息, 则触发 S1 口的建立, 例如发送 Initial UE message (初始 UE消息) 给 MME。 然后在基站和 MME建立 UE的上下 文(具体包括 MME向基站发送的建立 UE上下文请求、 基站与 UE间的 RRC Reconfiguration, 基站向 MME发送的建立 UE上下文响应等步骤, 该过程为 本领域的公知常识, 此处不做贅述), 使 UE进入 LTE的连接态。
步骤 1306,当有下行数据到达 MME时, MME就可触发专用承载的建立, 将数据通过 AP下发给 UE。 与上述通讯方法实施例 1 相对应的, 本发明实施例还提供一种基站实施 例 1, 参见图 15, 所述基站包括:
