Description

网络控制器及用户面管理方法
[1] 技术领域
[2] 本发明涉及通信技术领域, 尤其涉及网络控制器及用户面管理方法。
[3] 发明背景
[4] 目前第三代移动通信网络中的接入网络模型如图 1所示, 图 1中虚线表示信令接 口, 实线表示数据和信令接口。 所述接入网络中包括: 家乡代理、 接入网关、 信令无线网络控制器 /会话参考网络控制器 (SRNC) 、 演进的基站等。 SRNC可 以称为信令无线网络控制器、 也可以称为会话参考网络控制器, 各设备的功能 如下:
家乡代理 (HA) , 用于提供移动性解决方案, 在演进网络中, 还可以支持不 同接入技术间的移动性管理;
接入网关 (AGW) , 用于提供用户 IP业务接入, 是终端的第一跳 IP路由器; SRNC, 负责维护无线接入特定的信息, 维护空口会话参数, 提供空闲态管理 和寻呼控制功能, 还负责对终端进行接入鉴权等操作;
[8] 演进的基站 (eBS) , 提供物理的空口传输, 以使终端接入无线网络, 所述 eB
S可具有数据附着点 DAP功能。 服务 eBS (Serving
eBS) 是当前与终端有空口物理连接的 eBS。 所述具有 DAP功能的 eBS是指与 AG
W建立了隧道绑定关系的 eBS, 负责从 AGW接收终端的前向链路数据。
[9] 当所述 eBS担当 DAP吋, AGW可以根据隧道绑定信息将前向数据传输到 DAP; 服务 eBS负责将空口接收到反向数据通过 DAP传输到 AGW。
[10] 所述服务的演进基站 Serving eBS分为前向和反向两种, 前向 Serving
eBS和反向 Serving
eBS可以是同一个 eBS, 也可以是不同的 eBS。 非服务 eBS与终端之间的信令需要 进行封装, 通过隧道在 Serving eBS的无线链路协议 (RLP) 上转发。
[11] 数据在接入网关和终端之间传输的示意图如图 2所示。 eBS检测到自己成为服务 eBS后, 将和充当 DAP的 eBS之间建立隧道。 充当 DAP的 eBS是终端的数据锚点 , DAP从 AGW收到终端的数据后, 将数据通过和服务 eBS之间的隧道发送到终 端的当前服务 eBS。
[12] 对于反向数据, 服务 eBS可以直接发送到外部 IP网, 或者先通过隧道发送到 DA
P, 再由 DAP转发到 AGW。
[13] 上述数据传输过程存在一个问题: 当终端已经离开 DAP的服务范围吋, 发往终 端的数据也还是会先发到所述 DAP, 再通过隧道转发到服务 eBS, 然后才发送给 终端, 这导致数据的传输路径过长, 传输吋延过大。
[14] 针对上述问题, 需要所述 DAP能够进行迁移, 由当前比较靠近终端的 eBS来充 当迁移后的 DAP, 如当前的服务 eBS成为 DAP, 使路由路径最短, 这样可以提高 路由效率。
[15] 现有技术中, DAP的选择由接入终端完成, DAP与 AGW之间的用户面隧道由 D
AP发起建立, 由 DAP来决定需要连接的 AGW。 具体操作如下所述:
[16] 在终端初始接入吋, 用户面承载建立的流程如图 3所示, 包括:
1、 AT (接入终端) 和 eBS建立空口连接, SRNC给 AT分配 UATI (单播接入终 端标识符) 。 AT和 eBS进行会话配置, 配置完成后会话信息存储在 SRNC;
[18] 2、 AT执行接入认证过程;
[19] 3、 AT指定当前的 eBS为 DAP;
[20] 4、 所述作为 DAP的 eBS选择一个 AGW, 向选择的 AGW发起绑定请求, 请求建 立用户面承载;
[21] 5、 AGW响应绑定请求, 此步骤后, 作为 DAP的 eBS和 AGW间的用户面承载已 经建立;
[22] 6、 eBS通知终端自己成为 DAP;
[23] 7、 eBS通知 SRNC自己为 DAP; 如果这吋路由集中有其它 eBS, eBS也会通知其 它 eBS;
[24] 8、 SRNC应答。
[25] 上述过程为终端初始接入的流程, 终端已经接入网络后, DAP迁移的流程如图
4所示, 包括:
[26] 1、 AT向目标 DAP发起 DAP迁移请求; [27] 2、 目标 DAP向 AGW发起绑定请求, 请求建立用户面承载;
[28] 目标 DAP可能从源 DAP获得 AGW地址;
[29] 3、 AGW响应绑定请求, 此步骤后, 目标 DAP和 AGW间的用户面承载建立; [30] 4、 目标 DAP通知终端自己成为 DAP;
[31] 5、 目标 DAP通知 SRNC自己为 DAP;
[32] 6、 SRNC应答;
[33] 7、 目标 DAP通知源 DAP自己为 DAP。 如果路由集中有其它 eBS, 目标 DAP也会 通知其它 eBS;
[34] 8、 源 DAP应答。
[35] 上述现有技术的缺点在于:
[36] 1) 由 AT来确定目标 DAP, 由于 AT并不确切知道网络侧实体的情况, 如 eBS的 数据处理能力、 当前的负荷情况等, 因此 AT指定的 eBS有可能并不适合充当 DA
2) 由 DAP来选择 AGW, 发起用户面承载建立, 这样需要在 eBS配置可以连接 的 AGW地址, 或者通过本地 DNS (域名系统) 服务来动态获得可用的 AGW。 分 别在 eBS配置 AGW地址会导致需要配置的实体很多, 不利于运营和维护。 所有 的 eBS都要支持 DNS能力造成 eBS的实现复杂化;
[38] 3) 现有技术没有考虑用户面承载建立的授权问题。
[39] 发明内容
[40] 本发明实施例提供网络控制器及用户面管理方法, 解决了现有技术由 DAP选择 AGW吋需要在每个 eBS上配置 AGW地址, 导致的运营及维护困难的问题, 同吋 简化了 eBS的实现。
[41] 本发明实施例提供一种用户面管理方法, 包括:
[42] 在需要为终端建立用户面承载吋, 网络控制器选择为终端提供服务的接入网关
[43] 将所述为终端选择的接入网关通知给所述终端的数据附着点。
[44] 本发明实施例提供一种网络控制器, 包括:
[45] 接入网关选择模块, 用于为接入终端选择可以提供服务的接入网关; 以及 [46] 用于将所述为终端选择的接入网关通知给所述终端的数据附着点的模块。
[47] 本发明实施例提供一种用户面管理方法, 包括:
[48] 网络控制器选择数据附着点;
[49] 向所述选择的数据附着点发送数据附着点分配 /迁移消息;
[50] 建立所述数据附着点与接入网关之间的用户面承载。
[51] 由上述本发明实施例提供的技术方案可以看出, 本发明实施例由 SRNC来确定 与 eBS连接的 AGW, 可以避免在每个 eBS上配置 AGW地址, 便于运营和维护, 同吋简化 eBS的实现。

[65] 实施本发明的方式
[66] 下面结合附图对本发明实施例所提出的技术方案进行详细说明。
[67] 本发明实施例通过 SRNC (本发明的技术方案并不限于 SRNC, 所有与 SRNC具 有类似功能, 且可作为集中点的实体均可以实现, 本发明实施例仅以 SRNC为例 进行说明) 来分配与 eBS连接的 AGW, 所述分配情况可以由 SRNC主动通知给 eB S, 也可以在 eBS与所述 AGW建立用户面承载前, SRNC根据请求通知给 eBS。 此 处所述的 eBS为担当 DAP功能的 eBS。 下文中与 AGW建立用户面承载的 eBS均为 担当 DAP功能的 eBS。
[68] 本发明实施例还可以由所述 SRNC来建立 eBS和 AGW间的用户面承载; 进一步 可以由所述 SRNC来负责释放用户面承载。
[69] 所述 SRNC作为集中点, 也可以用来指定当前的 DAP。
[70] 下面以不同的场景详细阐述本发明实施例的技术方案。
[71] 场景一: 终端初始接入
[72] 本发明实施例提供的方案包括如下四种:
[73] (1) DAP由 SRNC指定, 用户面承载建立由 eBS发起
[74] 具体流程如图 5所示, 包括如下步骤:
[75] 步骤 1 : AT和 eBS建立空口连接, SRNC给 AT分配 UATI;
[76] AT和 eBS进行会话配置, 配置完成后会话信息存储在 SRNC;
[77] 步骤 2: AT执行接入认证过程;
[78] 步骤 3: SRNC选择一个为 AT提供服务的 AGW, 可以指定当前的 eBS为 DAP, 将 AGW地址及 DAP指配消息通知给 eBS;
[79] SRNC指配的 DAP可能与当前 Serving
eBS不同, SRNC需要将指定的 DAP通知给路由集中的所有 eBS; SRNC可以通过 通知消息来通知路由集中的所有 eBS。
[80] SRNC还可以在所述通知消息中携带为建立用户面承载所需要的参数, 如用户 面承载釆用 PMIP信令, 则在所述通知消息中携带生成 PMIP信令所需要的密钥材 料;
[81] SRNC也可以生成绑定请求消息, 封装在 DAP分配消息中传递给 eBS, 这样 eBS 可以直接将封装的绑定请求消息发送给指定的 AGW;
[82] 所述 SRNC分配 DAP, DAP建立用户面承载的过程, 可以是基于 AT向 SRNC发 起 DAP分配请求来触发, 也可以是 SRNC根据当前还没有分配 DAP, 导致 SRNC 主动发起此请求。
[83] 步骤 4: eBS向 SRNC指定的 AGW发起绑定请求, 请求建立用户面承载;
[84] 步骤 5: AGW响应绑定请求, 此步骤后, eBS和 AGW间的用户面承载建立; [85] 步骤 6: eBS 向 SRNC发送绑定分配应答消息。 如果返回成功应答, SRNC保存当前 DAP。
[86] eBS也可以将绑定响应消息封装在绑定分配应答消息中传递给 SRNC。
[87] (2) DAP由 SRNC指定, 用户面承载建立由 SRNC发起
[88] 具体流程如图 6所示, 包括如下步骤:
[89] 步骤 1 : AT和 eBS建立空口连接, SRNC给 AT分配 UATI。 AT和 eBS进行会话配 置, 配置完成后会话信息存储在 SRNC;
[90] 步骤 2: AT执行接入认证过程;
[91] 步骤 3: SRNC选择一个为 AT提供服务的 AGW, 可以指定当前的 eBS为 DAP, 由 SRNC向 AGW发送绑定请求消息, 请求建立用户面承载, 所述绑定请求消息 中带有指定的 DAP地址;
[92] 所述 SRNC发起用户面承载建立请求, 可以是基于 AT向 SRNC发起 DAP分配请 求来触发, 也可以是 SRNC根据当前还没有分配 DAP, 导致 SRNC主动发起此请 求。
[93] 步骤 4: AGW响应绑定请求, 此步骤后, eBS和 AGW间的用户面承载建立; [94] 步骤 5: SRNC向指定的 eBS发送 DAP分配消息, 将 AGW地址通知给 eBS, 如果 路由集中有其它 eBS, 还需通知其它 eBS进行了 DAP分配;
[95] SRNC还可以在消息中携带用户面承载使用所需要的参数, 如用户面承载釆用
GRE隧道, 则需要将 eBS使用的 GRE密钥材料通知给 eBS;
[96] 步骤 6: eBS向 SRNC发送应答消息。
[97] (3) DAP仍然由终端指定, 用户面承载建立由 eBS发起
[98] 具体流程如图 7所示, 包括如下步骤:
[99] 步骤 1 : AT和 eBS建立空口连接, SRNC给 AT分配 UATI。 AT和 eBS进行会话配 置, 配置完成后会话信息存储在 SRNC;
[100] 步骤 2: AT执行接入认证过程;
[101] 步骤 3: AT指定当前的 eBS为 DAP;
[102] 步骤 4: eBS向 SRNC发起承载建立请求;
[103] 步骤 5: SRNC选择一个为 AT提供服务的 AGW, 发送承载建立响应给 eBS, 所 述响应消息中携带 AGW地址, 也可以携带建立承载所需要的参数。 如果没有可 用的 AGW, 会返回拒绝指示;
[104] 步骤 6: eBS向 SRNC指定的 AGW发起绑定请求, 请求建立用户面承载;
[105] 步骤 7: AGW响应绑定请求, 此步骤后, eBS和 AGW间的用户面承载建立; [106] 步骤 8: eBS通知 SRNC承载建立完成。 如果步骤 7中返回失败指示, eBS通知 SR
NC承载建立失败;
[107] 步骤 9: 建立用户面承载成功后, eBS向 AT发送 DAP分配消息。
[108] (4) DAP仍然由终端指定, 用户面承载建立由 SRNC发起
[109] 具体流程如图 8所示, 包括如下步骤:
[110] 步骤 1 : AT和 eBS建立空口连接, SRNC给 AT分配 UATI。 AT和 eBS进行会话配 置, 配置完成后会话信息存储在 SRNC;
[111] 步骤 2: AT执行接入认证过程;
[112] 步骤 3: AT指定当前的 eBS为 DAP;
[113] 步骤 4: eBS向 SRNC发起承载建立请求;
[114] 步骤 5: SRNC选择一个为 AT提供服务的 AGW, 由 SRNC向 AGW发送绑定请求 消息, 请求建立用户面承载, 消息中带有指定的 DAP地址;
[115] 步骤 6: AGW响应绑定请求, 此步骤后, AGW设置和 eBS间的用户面承载; [116] 步骤 7: SRNC向指定的 eBS发送承载建立响应消息, 将 AGW地址通知给 eBS。
SRNC还可以在消息中携带用户面承载使用所需要的参数, 如用户面承载釆用 G
RE隧道, 则需要将 eBS使用的 GRE
key通知给 eBS。 DAP根据返回的 AGW信息建立用户面隧道;
[117] 步骤 8: 建立用户面承载成功后, eBS向 AT发送 DAP分配消息。
[118] 上述场景一中的各实施例为用户初始接入吋的用户面管理方案, 上述各实施例 通过网络侧实体 SRNC选择为 AT提供服务的 AGW, 避免了由 DAP选择 AGW带来 的实现复杂及运营维护困难等问题;
[119] 另外, 由于 SRNC是接入认证的认证者, 保存用户的配置信息和密钥材料, 因 此由 SRNC建立用户面的承载方案可以解决现有技术用户面承载建立过程没有考 虑授权的问题;
[120] 再者, 由 SRNC来确定 DAP的方案解决了现有技术由终端指定 DAP方案中, 由 于终端不了解网络侧情况而导致的所选择的 DAP不是最佳 DAP的问题。
[121] 场景二: 终端已经接入网络, 进行 DAP迁移吋
[122] 本发明实施例提供的技术方案包括如下四种:
[123] (1) DAP由 SRNC指定, 用户面承载建立由 eBS发起
[124] 具体流程如图 9所示, 包括如下步骤:
[125] 步骤 1 : SRNC选择一个 eBS作为目标 DAP, 向所述目标 DAP发送 DAP迁移请求 消息, 所述消息中携带原来为 AT提供服务的 AGW;
[126] SRNC发起 DAP迁移请求可以是基于 AT向 SRNC发起 DAP迁移请求来触发, 或 者根据当前 eBS和源 DAP距离超过规定值, 导致 SRNC主动发起此请求;
[127] 所述 SRNC还可以在消息中携带为建立用户面承载所需要的参数, 如用户面承 载釆用 PMIP信令, 则提供生成 PMIP信令所需要的密钥材料;
[128] SRNC也可以生成绑定请求消息, 然后封装在 DAP迁移消息中传递给目标 DAP
, 这样目标 DAP可以直接将封装的绑定请求消息发送给指定的 AGW。
[129] 步骤 2: 所述目标 DAP向 SRNC提供的 AGW发起绑定请求, 请求建立用户面承 载;
[130] 步骤 3: AGW响应绑定请求, 此步骤后, 目标 DAP和 AGW间的用户面承载建 [131] 步骤 4: 目标 DAP向 SRNC发送 DAP迁移响应消息;
[132] 如果返回成功应答, 则 SRNC保存当前 DAP; 目标 DAP也可以将绑定响应消息 封装在应答消息中传递给 SRNC;
[133] 步骤 5: SRNC通知源 DAP现在的 DAP已经改变;
[134] SRNC还会通知路由集中的其它 eBS当前 DAP已经改变, 通知 DAP改变的消息 也可以由目标 DAP发起;
[135] DAP更改之后, 后续的前反向数据可以通过新 DAP进行通信。
[136] (2) DAP由 SRNC指定, 用户面承载建立由 SRNC发起
[137] 具体操作流程如图 10所示, 包括如下步骤:
[138] 步骤 1 : SRNC向为 AT提供服务的 AGW发送绑定请求消息, 请求在目标 DAP和 AGW间建立用户面承载, 消息中带有目标 DAP地址; [139] SRNC向 AGW发送绑定请求, 发起 DAP迁移请求过程可以是基于 AT向 SRNC发 起 DAP请求来触发, 或者根据当前 eBS和源 DAP距离超过预定值, 导致 SRNC主 动发起此请求;
[140] 步骤 2: AGW响应绑定请求, 此步骤后, 目标 DAP和 AGW间的用户面承载建
[141] 步骤 3: SRNC向目标 DAP发送 DAP迁移通知消息, 将 AGW地址通知给目标 DA P;
[142] SRNC还可以在消息中携带用户面承载使用所需要的参数, 如用户面承载釆用
GRE隧道, 则需要将目标 DAP使用的 GRE密钥材料通知给目标 DAP;
[143] 步骤 4: 目标 DAP向 SRNC发送应答消息;
[144] 步骤 5: SRNC通知源 DAP当前的 DAP已经改变;
[145] SRNC还会通知路由集中的其它 eBS当前 DAP已经改变; 通知 DAP改变的消息 也可以由目标 DAP发起。
[146] (3) DAP仍然由终端指定, 用户面承载建立由 eBS发起
[147] 具体操作流程如图 11所示, 包括如下步骤:
[148] 步骤 1 : AT向目标 DAP发起 DAP迁移请求;
[149] 步骤 2: 目标 DAP向 SRNC发起承载建立请求;
[150] 步骤 3: SRNC发送承载建立响应给目标 DAP, 消息中携带当前提供服务的 AG
W地址, 还可以携带建立承载所需要的参数;
[151] 步骤 4: 目标 DAP向 SRNC提供的 AGW发起绑定请求, 请求建立用户面承载; [152] 步骤 5: AGW响应绑定请求, 此步骤后, 目标 DAP和 AGW间的用户面承载建
[153] 步骤 6: 目标 DAP通知 SRNC承载建立完成;
[154] 如果步骤 5中返回失败指示, 目标 DAP通知 SRNC承载建立失败;
[155] 步骤 7: 建立用户面承载成功后, 目标 DAP向 AT发送 DAP分配消息;
[156] 步骤 8: SRNC通知源 DAP当前的 DAP已经改变;
[157] SRNC还会通知路由集中的其它 eBS当前 DAP已经改变; 通知 DAP改变的消息 也可以由目标 DAP发起。 [158] (4) DAP仍然由终端指定, 用户面承载建立由 SRNC发起

[168] SRNC还会通知路由集中的其它 eBS当前 DAP已经改变; 通知 DAP改变的消息 也可以由目标 DAP发起。
[169] 上述场景二中的各实施例为用户已经接入网络, 进行 DAP迁移吋的用户面管理 方案, 上述场景二中的各实施例通过网络侧实体 SRNC选择为 AT提供服务的 AG
W, 避免了由 DAP选择 AGW带来的实现复杂及运营维护困难等问题;
[170] 另外, 由于 SRNC是接入认证的认证者, 保存用户的配置信息和密钥材料, 因 此由 SRNC建立用户面的承载方案可以解决现有技术用户面承载建立过程没有考 虑授权的问题;
[171] 再者, 由 SRNC来确定 DAP的方案解决了现有技术由终端指定 DAP方案中, 由 于终端不了解网络侧情况而导致的所选择的 DAP不是最佳 DAP的问题。
[172] 本发明实施例还提供一种信令无线网络控制器 /会话参考网络控制器 (SRNC) , 所述信令无线网络控制器 /会话参考网络控制器设置有:

[178] 综上所述, 本发明实施例由 SRNC来确定为接入终端提供服务的 AGW, 可以避 免在每个 eBS上配置 AGW地址, 便于运营和维护, 同吋简化 eBS的实现;
[179] 另外, SRNC是接入认证的认证者, 保存有用户的配置信息和密钥材料。 eBS 易于被攻击, 由 SRNC来建立用户面的承载, 有利于用户面管理的安全, 降低安 全风险;
[180] 再者, 由网络侧实体来确定 DAP, 可以根据网络侧实体的处理能力、 负荷情况 , 指定最合适的 eBS来充当 DAP。 终端可以不用知道当前是哪个 eBS充当 DAP, 简化终端实现。
[181] 以上所述, 仅为本发明较佳的具体实施方式, 但本发明的保护范围并不局限于 此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易想到 的变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保护范围 应该以权利要求的保护范围为准。
