LTE***是对第三代移动通信***的演进， 整个 LTE***由 eNB、 EPC 和 UE三部分组成，图 1所示为 LTE***的网络架构图， eNB是演进型基站， EPC负责核心网部分，包括 MME和 S-GW, UE是用户终端，其中， E-URTAN 侧的多个 eNB通过 S 1接口接入 MME/S-GW ,各 eNB之间通过 X2接口连接。
随着宏网网络（3G网络或 LTE网络）规模不断扩大， 用户数量不断增 加， 用户的数据带宽需求不断加大。 由于 3G网络和 LTE网络的使用频率较 高， 与 GSM相比， 其信号穿透能力较差， 因此室内覆盖成为网络优化的一 个难点， 一般会釆用设立室内分布***的方式来实现 3G网络或 LTE网络的 室内覆盖。 但是， 在现有条件下， 室内分布***一般只能架设在一些酒店、 中高档小区或公共热点场所。 对于一般的居民小区， 受限于各种条件， 还无 法架设室内分***， 因此， 室内 3G或者 LTE信号很弱甚至根本没有信号， 对用户体验造成很大影响。
为此已提出一种 Femto***， 即家庭基站***， 其釆用的公共宽带或者 运营商传输接入是通过因特网接入到安全网关及运营商的核心网， 从而为用 户提供无线信号覆盖，可改善用户体验，是室内覆盖补盲、补热的重要技术。 关于 Femto***， 其主要由家庭基站和 femto网关组成， 其中家庭基站根据 其釆用的无线技术不同分为使用 3G制式的家庭基站和使用 LTE制式的家庭 基站 HeNB。
图 2所示为 LTE制式的 Femto***网元架构图 ,在 LTE***引入 HeNB GW, 其下链接多个 HeNB。 首先， HeNB GW通过 S1链路一对多地连接多 个 HeNB, 其次， HeNB GW通过 SI链路还一对多地接入多个 MME/S-GW 进行负荷分担和容灾备份。另外 , HeNB也可通过 S1直接接入 MME/S-GW。
LTE制式的 Femto***的其它网元还包括 HeMS (图 2中未示出 ) , 用于配 置 HeNB的相关参数。
对于宏网基站 eNB, 在目前的协议 ( 36413 ) 中规定， eNB与 MME之 间的 S 1消息仅支持最大 256个跟踪区域码 TAC，最大 256个闭合用户组 CSG , 最大 6个广播公共陆地移动网络 PLMN。 在小区数目有限的情况下， 该协议 的规定的最大值在宏网 eNB***中不会产生问题。
但是，对于家庭基站 HeNB，在引入 HeNB GW之后 , HeNB GW在 MME 看来就是一个宏网 eNB,—个宏网 eNB与单个 MME/S-GW之间仅有一条 S1 链路， 而一个 HeNB GW下可能链接几万甚至几十万的 HeNB, 这时原协议 所规定的上述最大值是远远无法满足组网需求的。典型的情况是，引入 HeNB GW之后，其下挂的 HeNB数目众多，但可用资源有限，有可能发生 HeNB GW 下某一 HeNB的 TAC ( 8 ) /CSG ( 8 )没能在消息中上报给 MME的情况， 由 于寻呼消息是按照 TAC/CSG进行寻呼的， 若 MME没有收到关于 TAC ( 8 ) /CSG ( 8 )的消息， 可能会认为 HeNB GW下没有 TAC为 8、 CSG为 8的小 区， 那么用于 TAC为 8、 CSG为 8的寻呼消息就不会下发到 HeNB GW, 该 小区的用户也就永远不可能接收到寻呼消息。
发明内容
为了解决相关技术中 HeNB GW容量无法满足实际组网需求的问题， 本 发明提供了一种 LTE制式家庭基站***中扩大网关容量的方法和装置。
一方面， 本发明的 LTE制式家庭基站***中扩大网关容量的方法包括： 网关 HeNB GW确定需要在其自身和单个移动管理实体 MME之间建立多个 S1链接； 针对每一个需要建立的 S1链接， 所述 HeNB GW设置不同的全网 eNB标识 Global eNB ID, 再分别向所述单个 MME发起 S1建立请求， 同时 携带 S1应用配置信息； 基于所述 S1建立请求和所述 S1应用配置信息， 所 述 HeNB GW在其自身和所述单个 MME之间建立多个 S1链接。
优选地， 可根据现网规划确定需要建立的所述多个 S1 链接的数目， 也 可根据实时或定期的***统计数据确定需要建立的所述多个 S1链接的数目。
优选地， 根据本次***统计数据确定当前需要建立的多个 S1 链接的数 目之后 , 通过增加、 删除或爹改以前建立的所述 HeNB GW和所述 MME之 间的多个 SI链接， 形成所述当前需要建立的多个 S1链接的数目
优选地， 所述多个 S1链接中的有限多个 S1链接建立在不同的 SCTP上 或建立在同一 SCTP承载的不同的流上。
另一方面，本发明的 LTE制式家庭基站***中扩大网关容量的装置包括: S1链接数确定模块， 设置为： 使网关 HeNB GW确定需要在其自身和单个移 动管理实体 MME之间建立多个 S1链接； S1链接请求模块， 设置为： 使所 述 HeNB GW针对单个 MME下每一个需要建立的 S1链接，设置不同的全网 eNB标识 Global eNB ID , 并分别向所述 MME发起 S 1建立请求， 同时携带 S1应用配置信息； 以及 S1链接建立模块， 设置为： 使所述 HeNB GW基于 所述 S1建立请求和所述 S1应用配置信息， 在所述 HeNB GW和所述单个 MME之间建立多个 S1链接。

以下结合附图以及实施例， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用以解释本发明， 并不限定本发明。
在如图 2的 LTE制式 Femto***架构中，从各网元的连接关系可以看到， 对于 MME, HeNB GW相当于宏站 eNB; 对于 HeNB, HeNB GW相当于 MME, 因此无论是 HeNB直接与 MME/S-GW链接 , 还是 HeNB经过 HeNB GW与 MME/S-GW链接， 其间的 S1接口的定义和功能是完全一致的。 为了 使 HeNB GW的容量不再受限于协议规定的 TAC、 CSG、 PLMN数量， 本发 明提供了一种 LTE制式家庭基站***中扩大网关 HeNB GW的容量的方法， 通过在 HeNB GW和 MME之间建立多条 S 1链接， 扩大 HeNB GW容量。
具体地，如图 3所示， S101 ,本发明的 HeNB GW首先确定与单个 MME 之间需要建立的 S1链接的数目； S102,针对单个 MME下每一个需要建立的 S1链接， HeNB GW设置不同的全网 eNB标识 Global eNB ID, 即虚拟出多 个不同的 eNB (按照协议， Global eNB ID包含 PLMN Identity和 eNB ID信 息，两者决定一个 eNB,也即设置一个 Global eNB ID相当于虚拟出一个 eNB ), 分别向 MME发起 SI建立请求， 同时携带 S1应用配置信息； S103 , 基于 S1 建立请求和 S1应用配置信息， HeNB GW在其自身与单个 MME之间建立多 个 S1链接。 每个 S1链接均可用来上传基站 S1消息， 可避免发生丟包消息 漏报的情况， 实质上扩大了 HeNB GW容量， 提高了***性能。
图 4所示为本发明第一实施例基于现网规划预估需要建立的 S1链接数 目， 按照该流程在 HeNB GW与单个 MME之间建立该数目的 S1链接。
S201 , HeNB GW根据现网规划预估需要支持的 TAC、 CSG和 PLMN 数目，进而确定在 HeNB GW与单个 MME之间建立 S1链接的数目， 并为单 个 MME下每个需要建立的 S1链接设置一个全网 eNB标识 Global eNB ID。
其中，确定需要的 S1链接数目时，如果需要支持的 TAC、 CSG和 PLMN 数目越多， 则需要的 S1 链接数目越多， 例如单个 MME下 TAC数目大于 256*N个， 需要的 S1链接的数目则为 N+l。
S202: HeNB GW向该 MME发起传输层承载 SCTP建立过程， 建立一 个或多个传输层承载 SCTP。
S203: HeNB GW针对每个 SI链接向该 MME发起 S1建立请求， 并在 请求消息中携带 S1应用配置信息，包括对应的 Global eNB ID、TAC、PLMN、 CSG、 默认寻呼不连续接收、 eNB名等。
S204:针对 MME接收到的每条 S1建立请求，按照常规方法处理以建立 需要的 S1链接，即如果 MME允许 S1建立，则本网元建立对应的 S1接口， 并发送 S1建立响应， 向 HeNB GW返回 S1建立应答消息， 其中携带 MME 的 S1配置信息， 如 MME名称、 PLMN、 MME组标识、 MME码字、 相对 MME能力，等等；如果 MME不允许 S 1建立（例如当核心网不支持 HeNB GW 配置时） ， 则建立失败， 向 HeNB GW返回 S1建立失败消息。
其中， 流控制传输协议 SCTP在两个端点之间提供稳定、 有序的数据传 递服务； 无线网络层协议 S1AP是 LTE ***接入网和核心网接口 S1-MME 的应用层协议， 控制接入网和核心网之间信令和数据的传输， 如图 5所示， S1AP协议建立在传输层承载 SCTP协议之上。 在本实施例中， 各个 S1链接 通过 S1AP协议建立在 SCTP上， 可以是建立在不同的 SCTP上， 如一个 S1 链接对应一个 SCTP; 也可以是多个 SI链接建立在同一 SCTP承载的不同流 上， 可根据当前的 SCTP传输能力选择设置， 通过将 S1建立于合适的 SCTP 传输承载上可增大 HeNB GW的数据流量。
按照本实施例的方法对***中每个 MME进行相同的操作 ,在 HeNB GW 和每个 MME之间分别建立多个 SI链接， 用于分担***数据传输。 以上， 在 S101中， HeNB GW按照现网规划确定需要建立的 S1链接数属于静态配置， 也可以通过动态的方法确定需要建立的 S1链接数。 图 6所示为本发明第二 实施例， 其根据实时或定期的统计数据动态地确定需要建立的 S1数目。
S301 , HeNB GW根据实时或定期的***统计数据确定需要与 MME之 间建立 S1链接的数目， 并为单个 MME下每个需要建立的 S1链接分配一个 Global eNB ID。
其中，所述统计数据可以是实时的或统计周期内的 HeNB数目、用户数、 信令流量或丟包率等， 需要处理的数据越多，应建立的 S1链接越多， 例如， 假如本次统计更新后发现单个 MME下 TAC数目多余 256*N个， 则本次的 S1链接数目为 N+l。 这样做的好处是， 如果***中新加入了家庭基站， 可动 态地及时调整 S1链接数， 自动达到合理的数目。
对于一次统计数据结果， 后续的处理流程 S302-S304 与第一实施例
S202-S204相同。
当再一次得到统计数据结果后， HeNB GW根据该更新的统计数据确定 当前需要的 S1 链接的数目， 在前一次配置的基础上， 通过增加、 删除或修 改与每个 MME之间的 S1链接，实现在 HeNB GW与每个 MME之间形成所 需数目的 S1 链接， 在合理的前提下最大程度地满足***资源需求； 并且在 这个动态调整的过程中，还可改变各 S1链接与所建立 SCTP的关系，根据当 前 SCTP传输能力选择将 S1建立在不同的 SCTP上或同一 SCTP承载的不同 流上， 进一步增大 HeNB GW容量。
另外， 为了解决相关技术中 HeNB GW容量无法满足实际组网需求的问 题， 本发明还提供了一种 LTE制式家庭基站***中扩大网关容量的装置， 如 图 7所示， 其包括： S1链接数确定模块 401 , 用于使网关 HeNB GW确定需 要在其自身和单个移动管理实体 MME之间建立多个 S1链接； S1链接请求 模块 402, 用于使所述 HeNB GW针对单个 MME下每一个需要建立的 S1链 接， 设置不同的全网 eNB标识 Global eNB ID , 并分别向所述单个 ΜΜΕ发 起 S1建立请求， 同时携带 S1应用配置信息； 以及 S1链接建立模块 403 , 用 于使所述 HeNB GW基于所述 SI建立请求和所述 S1应用配置信息， 在所述 HeNB GW和所述单个 MME之间建立多个 S1链接。
此外， 所述 S1 链接建立模块还用于在根据本次***统计数据确定当前 需要建立的 S1链接的数目之后，通过增加、删除或修改以前建立的所述 HeNB GW和所述 MME之间的多个 SI链接， 形成所述当前需要建立的 S1链接的 数目； 以及， 所述 S1链接建立模块还用于： 将所述多个 S1链接中的有限多 个 S1链接建立在不同的 SCTP上或建立在同一 SCTP承载的不同的流上。
将本发明的上述装置用于 LTE 制式家庭基站***中， 可实现在网关 HeNB GW与单个 MME之间建立多条 S 1链接， 达到扩大 HeNB GW容量的 目的。
在网关 HeNB GW与各个 MME之间建立多条 S 1链接之后，还需要建立 HeNB和 HeNB GW之间的一条 S1链接： HeNB向 HeNB GW发出 SI建立 请求， HeNB GW收到请求后， 在满足需求（即 MME支持该 HeNB的 SI建 立请求消息中的全部或部分 PLMN时 )的每个 MME与 HeNB GW之间的多 个 S1链接中，选择一个 S1链接驻留该 HeNB(如果有多个 MME满足需求， 最终可能会有多个 SCTP连接驻留该 HeNB,用于传输该 HeNB的 S1消息）， 成功驻留后向该 HeNB回复 S1链接建立响应， 驻留失败则回复 S1链接建立 失败消息。 其中， 从多个 S1链接中选择一个 S1链接进行 HeNB驻留时， 应 按照负载均衡的原则考虑，优先选择当前流量较小或挂接 AP较少的 S1链接 进行驻留。 由此， 当 HeNB GW收到 MME的寻呼消息后， 可根据寻呼消息 的 S1链接找到满足寻呼要求的 HeNB进行寻呼，可避免该 MME在其它 SCTP 上下发的相同寻呼消息被重复发送到同一个 AP。 尽管为示例目的， 已经公开了本发明的优选实施例， 本领域的技术人员 将意识到各种改进、 增加和取代也是可能的， 因此， 本发明的范围应当不限 于上述实施例。 工业实用性
本发明实施例有益效果如下：
1. 提供了一种在 HeNB G W与单个 MME之间建立多条 S 1链接的方法， 突破了 HeNB GW与 MME之间一条 S1链接所带来的限制， 能够在 所使用的协议的基础上扩大 HeNB GW容量， 满足组网需求。
2. 基于现网规划、 ***实时或周期性统计数据， 确定所需要的 S1链接 的数目，既能满足现网使用需求，又不至于浪费***资源建立空闲链 接。
3. 根据当前 SCTP传输能力选择将 S1 建立在不同的 SCTP上或同一 SCTP承载的不同流上， 进一步增大了 HeNB GW容量， 提高了*** 性能。
