Description

终端在 lx网络下建立 HRPD网络分组数据业务的方法 技术领域
本发明涉及一种终端与 HRPD网络进行信息交互的方法, 特别是一 种终端在 lx网络下建立 HRPD网絡分组数据业务的方法。 发明背景
CDMA2000 l 网络是目前用户规模最大的 CDMA网络, 以电路语 音业务和中低速数据业务为主。 CDMA2000 lx EV-DO是为了优化数据 应用而设计的, 也称为高速率分組数据 ( HRPD )„ HRPD版本 A的反向 链路可以达到 1.8Mbit/s, 而前向链路则可达到 3.1Mbit/s的峰值速率。 HRPD :性能优越的关键在于它使用了闭路速率控制 (Closed-loop rate control )和增强容量调度算法( Capacity enhancing scheduler )在可能的 最高速率下以突发的方式将数据传送给每个用户。 换句话说, 对调制方 法和传送时间的选择可以根据信道环境而做动态的控制以获取最佳的 效果。 ;
HRPD版本 A也有其他方面的增强, 包括服务廣量(QoS )、 即时多 媒体、 定位服务(LBS )、 均衡器、 接收分集、 VoIP和多载波。 QoS允 许 HRPD以不同的方式处理不同的应用, 例如 VoIP和可视电话, 因此, 运营商 ^以根据不同的数据用量和 QoS级别提供不同等级的计费。
HRPD可以独立地建成无线移动数据网络, 也可以与 lx混合组网 , 互为补充, 完成 ITU对 3G系统制定的功能要求。 出于 3G业务市场尚 未全面启动, 以及网络的建设成本方面的考虑, HRPD网络建设第一阶 段普遍采用热点覆盖的方案。 这样, 在 HRPD 网络的边缘必然存在 lx 和 HRPD 网络间的业务切换的问题; 同时, 在 HRPD网络内部, 出于 lx和 HRPD网络间负载调节的需要也会出现同样的问题。因此有必要对 lx和 HRPD网络间业务无缝切换进行研究,所述无缝切换即切换引起的 业务中断时间极低, 以实现两种网络间优势互补, 同时保证用户体验。
终端在 HRPD网络不占有无线业务信道, 但终端和 PDSN保持 PPP 逻辑连接, PDSN和 PCF保持 A10连接, 这称为终端与 HRPD网络存 在休眠歡据会话。 当网络有数据要发送给终端, 如果终端在监听 HRPD 网络, 则收到 AN下发的寻呼消息后主动发出连接建立请求以激活数据 会话, 网络会为其分配无线业务信道, 并建立有线连接, 然后进行数据 接收, 该有线连接为 A8连接; 如果终端在 lx网络下进行业务, HRPD 网络将请求 lx网络向终端发送寻呼信息,终端自行决策是否转入 HRPD 网络接收数据。 当终端有数据要发送给 HRPD网络, 则主动发起数据会 话激活。 数据传输完毕后, 如果一定时间内终端和 HRPD网络没有数据 交互, 则可能又进入数据会话休眠状态。 而休眠切换是指终端与 HRPD 网络存在分组数据业务休眠时, 由于终端的移动性, 需要将 HRPD会话 ( session )信息从源 AN/PCF转移到目标 AN/PCF, 为分组数据业务激 活做准备, 所述会话信息即 HRPD空口协议属性值和相关公共数据值, 而分组数据业务激活状态指的是业务数据传输状态。 这个过程中可能引 起 A10:连接切换, 该 A10连接是指 HRPD和 AN/PCF之间的连接, 即 新的连接建立, 旧的连接被释放。
如图 1和图 2所示, HRPD网络与 lx网络有两种不同的连通方式, 这两种方式可能同时存在, 其中, 在 HRPD网络侧, PDSN为分组数据 服务节 , PCF为分组控制功能, AN为接入网; 在 lx网絡侧, MSC 为移动交换中心, BSS为基站控制器。 第一种方式是 HRPD网絡和 lx 网络通过信令接口 Al/Alp连通,其中 A1接口基于电路连接, Alp基于 IP连接,信令接口 Al/Alp主要用来传递 lx电路业务相关信令; 第二种 方式是 HRPD网络和 lx网络通过信令接口 A21连通, A21接口主要用 来在终端进行 HRPD网絡业务时传递 lx空口相关消息。
对于单待机的 HRPD/lx双模终端来说, 不能同时启动两个无线接 口, 这^网络间切换带来困难, 如果终端在 lx 网络下进行业务时, 能 够借助; lx网络无线接口在 HRPD网络建立分组数据业务, 将对 lx和 HRPD网络间业务无缝切换十分有益。
目前,终端与 HRPD网络没有分组数据会话时,在 lx网络下与 HRPD 网络建立分组数据业务的过程为:
1 终端需要建立分组数据业务时, 在 lx网络的空口建立通道, 用 于承载终端和 HRPD网络之间的信息流;
2、 终端与接入网 (AN )建立 HRPD会话, 包括分配单播接入终端 标识(pATI )、 进行会话协商, 还可能进行接入鉴权等;
3、 :分配无线业务信道;
4、 AN和分组控制功能(PCF )建立连接, PCF和分组数据服务节 点 (PDSN )建立连接;
5、:终端和 PDSN建立点到点协议 ( PPP )连接, 可能进行移动 IP ( MIP )注册。
以上方法给出了终端与 HRPD网络没有分组数据会话时, 在 lx网 络下与 HRPD网络建立分組数据业务的方法,没有解决终端在 HRPD网 络已有休眠分组数据会话时,建立新的 HRPD网络分组数据业务的问题。 发明内容
本发明的目的在于提出一种终端与 HRPD网絡存在休眠分组数据会 话的情况下, 终端在 lx网络下建立 HRPD网絡分组数据业务的方法, 解决终端在 lx网络下进行业务, 且在 HRPD网絡已有休眠分组数据会 话时, 不能建立 HRPD网络分组数据业务的问题。
为实现上述目的, 本发明提出了一种终端在 lx 网络下建立 HRPD 网络分 ^数据业务的方法, 执行以下步骤:
a、终端向 HRPD网络目标接入网 /分组控制功能发起会话建立请求; b、 所述目标接入网 /分组控制功能获取已有 HRPD会话信息后, 与 所述终端建立 HRPD会话;

本发明通过终端在 lx网络下进行业务时,如语音业务,短消息业务 等,借助 lx空口及 lx网络与 HRPD网络 AN的连接发起 HRPD网络分 组数据业务建立, 并按需要进行 HRPD网络 AN间休眠切换, 从而解决 了终端在 lx网络下进行业务, 且在 HRPD网络已有休眠分组数据会话 时, 建 HRPD网络分组数据业务的问题。 有益于 lx和 HRPD网络间 业务无缝切换, 进而实现两种网络间优势互补和改善用户体验。 附图简要说明
图 1为现有技术中 HRPD网络与 lx网络基于 Al/Alp接口连通的结 构图; :
图 2为现有技术中 HRPD网络与 lx网络基于 A21接口连通的结构 图;
图 为本发明终端在 lx网络下建立 HRPD网络分组数据业务的方 法的实施例的流程图;
¾4为本发明的实施例中 lx网络的终端与 HRPD网络的 AN进行 信息交 ^的第一种方式的流程图;
图 5为本发明的实施例中 lx网络的终端与 HRPD网络的 AN进行 信息交互的笫二种方式的流程图。 实施求发明的方式
本发明的总体思想在于:终端在 lx网络下进行业务时,如语音业务, 短消息业务等, 借助 lx空口及 lx网络与 HRPD网络 AN的连接发起 HRPD网络分组数据业务建立。 另外, 在此过程中, 如果源 AN/PCF和 目标 AN/PCF不为同一 AN/PCF, 则需要进行 HRPD网络休眠切换。
本发明是在终端与 HRPD网络已有分组数据会话, 且该会话处于数 据会话休眠状态的情况下, 与 HRPD网络建立新的分组数据业务。 在建 立新业务的过程中, 如果源 AN/PCF和目标 AN/PCF不同, 则需要进行 休眠切换; 如果相同, 则直接执行业务建立的流程, 但该流程与现有技 术中没有分组数据会话的情况下, 建立新业务的流程有所不同, 本发明 只需修改已有 HRPD会话的配置, 并在其上增加相应的新业务即可, 而 不需为该业务建立一个新的 HRPD会话, 以及为该分组数据会话建立 PPP连 。
AN和 PCF是两个网络设备, HRPD网絡重要的会话管理 /移动性管 理功能可以在 AN, 也可以在 PCF实现。 然而, 实际的产品实现往往将 AN和 PCF做在一起, 它们之间可能采用私有接口。 为了描述方便, 本 文使用 AN/PCF对两种设备进行整体描述,但并不表示 AN和 PCF是一 一对应的, 比如(AN/PCF ) 1和(AN/PCF ) 2的 AN不同, 但 PCF可 能是同一个。 图 3为本发明终端在 lx网络下建立 HRPD网络分组数据业务的方 法的实施例的流程图, 本实施例具体执行以下步骤:
步骤 101、在 lx网络空口创建通道, 用以承载终端和 HRPD网络之 间的信 ^流; 创建通道有两种方法:
a.终端与 lx网络进行协商, 申请增加新的无线业务信道, 作为终端 与 HRPD网络之间的通道, 该通道可以为专用控制信道(DCCH ), 其流 程为: 终端向 BS发送业务请求消息, 包含业务配置信息记录, 记录中 包括复用选项、业务信道请求、业务 ID等; BS返回业务连接响应消息, 其中包含业务配置开始有效时间, 也包含业务配置信息记录, 记录中包 括复用选项、 业务信道指配、 业务 ID;
b.终端发起 lx分组业务请求,得到无线业务信道,作为终端与 HRPD 网络之间的通道, 但 lx BS不去建立与 lx PCF的 A8连接, 建立的通道 为补充码分信道(SCCH )或补充信道(SCH ), 其流程为: 终端向 BS 发送增强始呼消息; BS回复基站应答指令后, 向 MSC发送增加业务请 求消息:; MSC回复分配请求消息; BS与终端进行业务协商, 协商过程 同 a; ;
在建立的通道上, 方法 a建立的通道可以使用数据突发消息来承载 终端与 HRPD网络的信息流数据, 而方法 b建立的通道则可以直接传递 信息流歎据;
也可以利用现有的业务信道的信令传输能力, 使用已有业务所使用 的信道作为终端与 HRPD网络之间的通道, 无需另外建立 lx业务信道, 该通道为基本信道(FCH ),可以使用数据突发消息来承载终端与 HRPD 网络的信息流, 在这种情况下, 就无需再建立新的通道, 而直接执行步 骤 102;:
步驟 102、 终端向 AN/PCF发起 HRPD会话建立请求, 判断目标 AN/PCF与源 AN/PCF为同一 AN/PCF, 如果是, 则执行步骤 107; 否则 执行步璩 103;
步骤 103、 目标 AN/PCF从源 AN PCF获取该终端已有 HRPD会话 信息;
步輙 104、 终端与目标 AN/PCF完成 HRPD会话建立;
步骤 105、 目标 AN/PCF与 PDSN建立数据连接;
步驟 106、 源 AN/PCF与 PDSN释放旧的数据连接; 如果存在多个 休眠分组数据业务, 步骤 105和步骤 106需要执行多次, 直至多个业务 被切换到新的数据连接上;
步弊 107、 终端与目标 AN PCF进行会话配置, 其流程为: 终端向 目标 AN/PCF发送配置请求消息, 消息中包含属性记录, 将该属性记录 标记为 a; 目标 AN/PCF回复配置响应消息, 消息中包含属性记录 b, b 为终端与目标 AN PCF都支持的属性,是 a的子集,从而实现了对 IP流 的配置 i, 并更新 IP流的 QoS;
步驟 108、 目标 AN/PCF与 PDSN之间为分组数据业务建立连接; 其流程为: 目标 AN/PCF向 PDSN发送 Al 1注册请求消息, 其中包含目 标 AN PCF与 PDSN之间用于传递业务数据的 A10连接的生命周期; PDSN回复 All注册答复消息,完成 A10连接的建立,所述 All连接用 于传送目标 AN/PCF与 PDSN之间的信令。
步骤 108之后, 终端无需再和 PDSN建立 PPP连接。
在以上流程中, lx网络的终端与 HRPD网络的 AN/PCF之间的信令 传递有两种方式, 在第一种方式中, AN/PCF通过 Al/Alp接口与 MSC 连接, 另一种方式中, AN/PCF不经过 MSC, 而是通过 A21接口与 BS 直接连接。 笫一种传递方式的流程如图 4所示, 具体执行以下步骤: 其中, 终端向 AN/PCF发送信息时执行以下步驟: 步驟 201、终端通过 lx网络空口向 lx网络的 BS发送数据突发消息; 步骤 202、 BS通过 lx网络空口的通道在空口协议栈笫二层向终端 返回应答消息;
步骤 203、 BS通过 Al/Alp接口向移动交换中心发送应用数据发送 业务(ADDS )发送消息;
步骤 204、 移动交换中心向 AN/PCF发起应用数据发送业务寻呼;
AN/PCF向终端发送信息时执行以下步骤:
步骤 301、 AN/PCF向移动交换中心发送基站业务请求;
步糠 302、 移动交换中心向 AN/PCF返回基站业务响应后, 通过
Al/Al 接口向 BS发送应用数据发送业务发送消息;
步骤 303、 BS通过 lx网絡空口的通道向终端返回数据突发消息; 步 304、终端通过 lx网络空口的通道在空口协议栈笫二层向基站 发送应答消息;
步驟 305、 BS通过 Al/Alp接口向移动交换中心发送应用数据发送 业务发送消息应答;
步¼ 306、 移动交换中心向 AN/PCF发送业务数据已经成功发送给 终端的事件通知。
在以上方法中, 需要对现有协议进行相应修改, 具体包括: 扩展数 据突发消息,扩展 ADDS寻呼、 ADDS发送和基站业务请求消息的 ADDS User Ρώΐ字段的定义, 扩展事件通知消息 Event字段的定义。
1 )对 lx空口数据突发消息 DBM进行的扩展, 具体说是创建一个 新的数据突发类型, DBM消息格式和修改如下: 字段(Field ) 长度 ( Length ) (bits)
MSG— NUMBER 8
BURST— TYPE 6
UM_MSGS 8
NUM— FIELDS 8
CHARi 8
表 1
目前数据突发类型 BURST— TYPE已经使用到 '000111,,而 '001000' 至 '111101, 是保留的,可以选择一个如 '001000, 使用。其余字段 Field 的说明如下:
MSG— NUMBER是该 DBM消息在数据突发流中的序号;
NUM_MSGS是本次数据突发流中切分的 DBM消息总数;
NUM— FIELDS是该 DBM消息携带的数据字节数;
CHARi是该 DBM消息携带的数据。
2 ):对 ADDS寻呼消息的 ADDS用户部分( ADDS User Part )信息 元素的扩展为:
7 : 6 5 4 3 2 1 0 Octet
=> ADDS User Part: Al Element Identifier = [3DH] 1
Length― <variable> 2 保留 Data Burst Type = 3
[ [000011] (SMS),
[000101] (PDS),
[000110] (SDB),
[001000] (HRPD-INF) ]
MSB Application Data Message = <任意值 > 4
…:
LSB n 表 2
其中,数据突发类型( Data Burst Type )定义了一个建议新值 '001000, 以表征 用数据信息 ( Application Data Message )传递的是 H PD网络 应用数据信息, 即 DBM消息携带的数据。
3 )对 ADDS发送消息的 ADDS用户部分 ADDS User Part信息元素 的扩展为:
7 6 5 4 3 2 1 0 Octet
=> ADDS User Part: Length = <variable> 1 保留;【00】 Data Burst Type = 2
[ [000011] (SMS),
[000100] (OTASP),
[000101] (PDS),
[000110] (SDB),
[001000] (HRPD-腳)]
MSB Application Data Message = <任意值 > 3
■··
LSB n 表 3
其中,数据突发类型 Data Burst Type定义了一个建议新值 '001000, 以表征 Application Data Message传递的是 HRPD网络应用数据信息,即 DBM消息携带的数据。
4 );基站业务请求消息的 ADDS用户部分(ADDS User Part )信息元 素的扩展为:
Figure imgf000016_0001
表 4 其:中, Data Burst Type 定义了一个建议新值 ' 001000' 以表征 Application Data Message传递的是 HRPD网络应用数据信息, 即 DBM 消息携带的数据。
5 );事件通知消息的事件(Event )信息元素的扩展为:
Figure imgf000017_0002
Figure imgf000017_0003
Figure imgf000017_0001
其中, 定义一个新的事件标识符 (Event Identifier )类型, 以指示 HRPD网络应用数据信息已经成功发送给终端。
以上是终端与 HRPD网络的 AN/PCF进行信息交互的第一种方式, 在第二种方式中, 终端不经过 Ix MSC, 通过 A21接口与 AN/PCF进行 信息交 其流程如图 5所示, 具体执行以下步骤:
其中, 终端向 AN/PCF发送信息时执行以下步骤:
步驟 401、终端通过 lx网絡空口的通道向 lx网络的 BS发送数据突 发消息;
步骤 402、 BS通过 lx网络空口的通道在空口协议栈第二层向终端 返回应苓消息;
步 403、 BS通过 A21接口向 AN/PCF发送 A21 - HRPD空口消息; 步骤 404、 AN/PCF向 BS返回 A21 -应答;
AN PCF向终端发送信息时执行以下步骤:
步骤 501、 AN/PCF向 lx网络的 BS发送 A21 - HRPD空口消息; 步 # 502、 BS向 AN/PCF返回 A21 -应答后, 通过 lx网络空口的 通道向终端发送数据突发消息;
步驟 503、 终端通过 lx网络空口的通道在空口协议栈第二层向 BS 返回应答消息;
步骤 504、 BS向 AN/PCF发送业务数据已经成功发送给终端的事件 通知。
在以上方法中, BS与 AN通过 A21接口连接, 需要对现有协议进 行相应修改, 具体包括:
1 )对数据突发消息的扩展与第一种方式相同;
2 ):创建三个新的 A21接口消息: A21-HRPD空口消息用来在 BS和 AN PCF之间传递 HRPD网络相关信息; A21-应答用来在 BS和 AN/PCF 之间对进行 A21 -HRPD 空口消息应答; A21-事件通知消息用来通知 AN/PCF HRPD网络相关数据信息已经成功发送给终端。
在以上两种 lx网络的终端与 HRPD网络的 AN/PCF之间的信令传 递方式中, 分为两部分, 第一部分为终端与 BS之间的信令传递, 采用 空口进行传递, 另一部分为 BS与 AN/PCF之间的传递, 在有线连接上 进行传 ¾。
总乏, 以上所述仅为本发明的较佳实施例而已, 并非用于限定本发 明的保护范围。
