  • the present invention relates to the field of wireless communications, and in particular, to a notification and output method, system and device for selective IP data offload activation. Background technique
  • Selected IP Traffic Offload is a technology that allows user data to directly enter the Internet (Inetemet) or a specific IP network (such as a corporate network) through a macro base station, while other data is still transmitted through the core network, such as Figure 1 shows.
  • SIPT0 can be applied to home base stations as well as macro base stations.
  • the home base station here refers to Home NodeB or Home eNodeB, which together are simply referred to as H(e)NB.
  • H(e)NB Home NodeB
  • the current draft specification states that the terminal (UE) is unaware of whether the network uses SIPTO technology.
  • LTE Long Term Evolution
  • Inetemet Internet
  • data of a specific IP network will not go through the core network, thus reducing the resource usage of the user plane of the core network. In this way, the investment cost of the equipment and network of the network operator can be reduced.
  • Some Internet services when the user equipment (UE) does not transmit data, these services automatically end, such as the UE downloads the webpage through the browser (Web Browser), after downloading the webpage, between the UE and the server (Web Server) It automatically ends the web downloading business of both. When there is no data transmission and the IP address of the UE changes, the UE can directly use the new IP address for subsequent webpage downloading, without specific and additional operations. However, in some Internet services, when the UE does not transmit data, the activated services do not automatically end. The UE and the service servers (Server) also transmit some status data (similar to the heartbeat mechanism), mainly the service server.
  • Some Internet services when the UE does not transmit data, these services automatically end, such as the UE downloads the webpage through the browser (Web Browser), after downloading the webpage, between the UE and the server (Web Server) It automatically ends the web downloading business of both. When there is no data transmission and the IP address of the UE changes, the UE can directly use the new IP address for subsequent webpage downloading, without specific and additional operations. However,
  • Some data of the UE such as its IP address, the service identifier of the UE, is recorded, and the IP address of the UE is bound to the service identifier of the UE.
  • IP address For example, QQ, Messenger, Skype, etc. require the user to enter a username and password, and the server binds the user's IP address to the user's identity.
  • the service between the UE and the server is interrupted (data cannot be exchanged between the UE and the service), and the user must input again through the new IP address.
  • the user name and password are registered. When registering to the service server, the UE can use the subsequent service.
  • PDN packet data network
  • the PDN connection or bearer (Bearer) established for the SIPTO may be released. In this way, the PDN connection on this SIPTO or the traffic transmitted on the Bearer is interrupted.
  • SIPTO is activated during mobility management in idle state:
  • the new MME or the new gateway (GW) (or the Gateway GPRS Support Node (GGSN)) Triggering the previously established PDN connection or Bearer for SIPTO activation, re-establishing the previously established PDN connection or Bearer to a new Packet Data Gateway (PGW) or GGSN, this new PGW or GGSN and the current location of the UE More close.
  • GW Gateway GPRS Support Node
  • GGSN Gateway GPRS Support Node
  • a feature of this method is that only when the UE is in an idle state, the SIPTO activation operation can be performed, and at this time, the UE has no data transmission, and thus, the change of the IP address caused by the activation of the SIPTO does not affect many subsequent operations.
  • the operation of the business (such as web page download), but the business that needs to be registered as mentioned above is still interrupted.
  • SIPTO combination activation The above two methods are used in combination, that is, the SIPTO is activated simultaneously when the PDN connection is established in the first scheme, and when the UE is in the idle state and moves, the new MME or the new GW triggers the connection of the previously established PDN or Bearer performs SIPTO activation, which re-establishes the previously established PDN connection or Bearer to a new PGW or GGSN. This new PGW or GGSN is close to the current location of the UE.
  • Scheme 1 and Option 2 are independent. That is, after using scenario 1, you can not use scenario 2. Option 1 can be used when using scenario 2. Option 3 combines scenario 1 with scenario 2, with the ability to activate SIPTO in scenario 1 and SIPTO in mobile during the early phase of scenario 1.

Description

选择性 IP数据分流激活的通知及输出方法、 系统和设备 本申请要求在 2010年 4月 28日提交中国发明实施例局、 申请号为 201010162541.6、 发明 名称为"选择性 I P数据分流激活的通知及输出方法、 系统和设备"的中国发明实施例申请的优先 权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及无线通信领域, 尤其涉及一种选择性 IP数据分流激活的通知 及输出方法、 系统和设备。 背景技术
选择性 IP数据分流( Selected IP Traffic Offload, SIPTO )是一种允许用 户数据通过宏基站直接进入因特网( Inetemet )或特定 IP网络(如公司网络), 而其它数据仍通过核心网传输的技术, 如图 1 所示。 SIPT0可以应用于家庭 基站,也可以应用于宏基站。这里的家庭基站指 Home NodeB或 Home eNodeB , 它们一起简称为 H(e)NB。 目前的规范草案指出终端(UE )对网络是否使用了 SIPTO技术是无知的。
因为长期演进(LTE ) 系统可以支持高达 100Mbps 的接入速率, 当很多 的用户通过 LTE系统接入到核心网使用 IP业务时, 核心网的带宽需要很多。 使用 SIPTO技术后, 用户访问因特网 (Inetemet )或特定 IP网络的数据将不 经过核心网, 因此减少了核心网的用户平面的资源使用。 这样, 可以减少网 络运营商的设备与网络的投资成本。
一些 Internet业务, 当用户设备 ( UE ) 不传输数据时, 这些业务就自动 地结束, 如 UE通过浏览器(Web Browser )来下载网页, 当下载完网页后, UE与服务器(Web Server )之间就自动地结束两者的网页下载业务。 当没有 数据传输、 UE的 IP地址发生改变时, UE就可直接使用新的 IP地址进行后 面的网页下载, 无需特定的、 额外的操作。 但有些 Internet业务, 当 UE不传输数据时, 这些激活的业务不会自动结 束, UE与这些业务服务器(Server )之间还间隔地传输一些状态数据(类似 于心跳的机制 ), 主要是业务 Server记录了 UE的一些数据, 如其 IP地址, UE的业务标识, 并将 UE的 IP地址与 UE的业务标识进行绑定。 例如, QQ、 Messenger, Skype 等需要用户输入用户名、 密码的业务, 其服务器将用户的 IP地址与用户的标识进行了绑定。 即使 UE与 Server之间没有数据交互, 只 要 UE的 IP地址发生改变, 则 UE与 Server之间的业务就中断( UE与业务之 间不能进行数据的交互了 ),用户必须通过新 IP地址再次输入用户名、密码进 行注册, 当注册到业务服务器上时, UE才能使用后续的业务。
目前在 SA2讨论 SIPTO的技术方案时, 有如下三种方案:
第一种, 建立阶段激活 SIPTO:
当一个分组数据网 (PDN )连接建立时, 或一个承载(Bearer )建立时, 同时激活 SIPTO, 用户不能感知到 SIPTO被激活;
当用户移动时,如用户移动到新的移动性管理实体(MME )时,为 SIPTO 建立的 PDN连接或承载(Bearer )有可能被释放。 这样, 在这个 SIPTO上的 PDN连接或 Bearer上传输的业务就被中断。
第二种, 空闲状态下的移动性管理过程中激活 SIPTO:
当 PDN连接建立或一个 Bearer建立时, 并不要求是否激活了 SIPTO, 但 当用户处于空闲状态时, UE移动时, 新的 MME或新的网关(GW ) (或网关 GPRS支持节点( GGSN ) )触发将此前已建立的 PDN连接或 Bearer进行 SIPTO 激活 , 即将此前已建立的 PDN连接或 Bearer重新建立到一个新的分组数据网 关(PGW )或 GGSN, 此新的 PGW或 GGSN与 UE当前所在的位置比较近。
这种方法的一个特点是只允许在 UE处于空闲状态时, 才能进行 SIPTO 的激活操作, 而此时 UE没有数据的传输, 这样, 因 SIPTO的激活而引起的 IP地址的改变, 不影响很多后续的业务的操作(如网页下载), 但对于前面所 说的需要注册的业务还是被中断了。
第三种: SIPTO的组合激活: 是将上面的两种方法组合使用, 即在第一种方案中建立 PDN连接时同时 激活 SIPTO, 当 UE位于空闲状态且移动时,新的 MME或新的 GW触发将此 前已建立的 PDN连接或 Bearer进行 SIPTO激活 , 即将此前已建立的 PDN连 接或 Bearer重新建立到一个新的 PGW或 GGSN, 此新的 PGW或 GGSN与 UE当前所在的位置比较近。
其中方案 1与方案 2是独立的。也就是使用方案 1后,可以不使用方案 2。 使用方案 2时可以不使用方案 1。 方案 3是将方案 1与方案 2结合起来, 具有 方案 1早期就能激活 SIPTO和方案 2中在移动的过程中激活 SIPTO的特点。
对于上述方案 1 中的建立阶段激活 SIPTO, 若在 PDN连接建立或一个 Bearer建立的同时激活 SIPTO, 用户可能在此 PDN连接或 Bearer上传输一些 关键的数据, 或进行一些关键的应用。 当用户移动时, 则有可能这些关键的 数据传输或关键的应用被中断。
例如, 某些网站提供用户下载其开发的软件, 但是在下载前, 网站需要 用户注册一些个人的信息, 然后才允许下载, 当用户下载过程, 移动了位置, 其下载被中断, 再次下载此软件, 则有可能还要将上面的过程重复一次, 或 要求再次输入用户名与密码后, 才允许其下载, 总之, 这种操作非常复杂, 用户使用感受非常不好。
再例如, 如果用户通过 UE上的 Skype与朋友打电话, 当用户移动时, UE与网络的连接被中断, 用户需要与朋友再次进行打电话, 用户使用感受非 常不好。
在研究过程中, 发明人发现现有技术中存在以下技术问题:
对在用户与核心网侧间建立的 PDN连接或 Bearer进行 SIPTO激活操作 后, 用户对 SIPTO激活操作无知, 若用户发生了位置移动, 则在该 PDN连接 或 Bearer上承载的终端的业务可能被中断, 用户的使用体验大大下降, 网络 服务质量也受到影响。 发明内容 本发明实施例提供一种 SIPTO激活的通知方法和一种网络管理设备, 用 于解决用户终端无法获知网络侧的 SIPTO激活操作的问题。

A、 网络侧在会话管理过程中执行 SIPTO激活操作;

下面对本发明进行具体说明:
本发明实施例是解决在 PDN连接建立或 Bearer建立时激活 SIPTO时,由 于不通知 UE造成 UE在后续的业务使用过程中, 可能出现业务中断的问题。 但本发明实施例提出的方法同样也适用于空闲状态下的移动性管理过程中激 活 SIPTO时, 通知 UE。
本发明实施例的主要思想是在 SIPTO激活时给 UE提供指示。
发明实施例方法一: 当 UE建立一个 PDN连接时,当网络激活 SIPTO时, 网络需要指示 UE此 PDN连接的 SIPTO被激活。
实施例一:
基于本发明实施例方法提出,当 UE从 E-UTRAN系统发起建立一个 PDN 连接, MME在发送给 UE的 NAS消息 Activate Default EPS Bearer Context Request中增加一个 SIPTO激活的标识 SIPTO Activation Flag。 当此 SIPTO Activation Flag被包含在消息中或 SIPTO Activation Flag取一个特定值就表明 此 PDN连接的 SIPTO被激活。
在 EPS 系统中, 有两种方式建立一个 PDN连接, 一个是 UE在附着 ( Attach )过程中建立一个 PDN连接; 另一个过程中当 UE注册到网络后, UE通过发起一个 PDN连接请求,从而建立一个 PDN连接。 而 SIPT0的激活 主要是选择一个与 UE在物理或地理位置上很近的 PDN GW。 可能的方法是 通过 UE所在的跟踪区标识( TAI )或 UE所在的 ECGI来选择该 PDN GW。
虽然有两种 PDN连接的建立方式(一个是通过 Attach过程, 另一个是 通过 PDN连接建立过程), 但两种方式在 NAS流程上却非常相似。 如图 4A 所示, 下面的流程均可应用这两种 PDN的建立方式。
步骤 1 : UE发起一个 PDN连接, 则 UE发送 PDN连接请求 ( PDN Connectivity Request )消息给 eNodeB或 HeNB ,该消息中携带接入点名( APN )、 PDN类型 (PDN Type )、 协议配置选项 ( Protocol Configuration Options )、 请 求类型 ( Request Type )等信息。
步骤 2: MME根据 UE在步骤 1中提供的 APN或 Request Type, 及 UE 的签约数据, 及 MME中的配置的策略 ( Policy ) 决定对这个 PDN连接进行 SIPT0的激活。
MME进行 PDN GW的选择,选择一个离 UE在物理上或地址很近的 PDN
GW。 然后, MME发送创建会话请求( Create Session Request )消息给服务网 关 (Serving GW ), 该消息中携带国际移动用户标识码(IMSI )、 2G/3G手机 号码( MSISDN )、控制面的 MME隧道端点标识( MME TEID for control plane )、 无线接入类型 (RAT type )、 PDN 网关地址( PDN GW address )、 PDN地址 ( PDN Address )、默认 EPS 承载服务质量( Default EPS Bearer QoS )、 PDN类 型(PDN Type )、 签约接入点名 AMBR ( subscribed APN-AMBR ), 接入点名 ( APN )、 EPS 载标识( EPS Bearer Id )、协议配置选项( Protocol Configuration Options ), 切换指示( Handover Indication )、 ME标识( ME Identity )、 用户位 置信息(User Location Information (ECGI) )、 移动用户信息变更报告支持指示 ( MS Info Change Reporting support indication )、 选择模式 ( Selection Mode ) , 计费特征( Charging Characteristics )、 跟踪参考 ( Trace Reference )、 跟踪类型 ( Trace Type )、触发器标识( Trigger Id )、操作维护中心标识( OMC Identity )、 最大 APN区域( Maximum APN Restriction )、双重地址 载标志( Dual Address Bearer Flag )等信息。
步骤 3: Serving GW发送 Create Session Request消息给 PDN GW, 该消 息中携带 IMSI、 MSISDN、 Serving GW Address for the user plane、 Serving GW TEID of the user plane、 Serving GW TEID of the control plane、 RAT type、 Default EPS Bearer QoS, PDN Type、 PDN Address, subscribed APN- AMBR、 APN, Bearer Id、 Protocol Configuration Options、 Handover Indication、 ME Identity、 User Location Information (ECGI) ^ MS Info Change Reporting support indication、 Selection Mode、 Charging Characteristics、 Trace Reference、 Trace Type、 Trigger Id、 OMC Identity、 Maximum APN Restriction、 Dual Address Bearer Flag等信 息。
步骤 4: PDN GW返回创建会话响应 ( Create Session Response ) 消息给 Serving GW, 该消息中携带用户面的 PDN GW地址( PDN GW Address for the user plane )、 用户面的 PDN GW隧道端点标识(PDN GW TEID of the user plane )、控制面的 PDN GW隧道端点标识( PDN GW TEID of the control plane )、 PDN类型( PDN Type )、 PDN地址( PDN Address )、 EPS 承载标识( EPS Bearer Id )、 EPS 承载服务质量 (EPS Bearer QoS )、 协议配置选项 (Protocol Configuration Options ), 计费标识 (Charging Id )、 禁止负载压缩 (Prohibit Payload Compression ), APN 约束( APN Restriction )、 原因 ( Cause )、 移动用 户信息变更才艮告动作 (MS Info Change Reporting Action ), 接入点名 AMBR ( APN- AMBR )等信息。
步骤 5: Serving GW返回 Create Session Response消息给 MME, 该消息 中携带 PDN Type、 PDN Address, Serving GW address for User Plane、 Serving GW TEID for User Plane、 Serving GW TEID for control plane、 EPS Bearer Id、 EPS Bearer QoS、 Protocol Configuration Options、 Charging Id、 Prohibit Payload Compression、 APN Restriction、 Cause、 MS Info Change Reporting Action (Start), APN- AMBR等信息。 步骤 6: MME发送激活默认 EPS 承载上下文请求(Activate Default EPS Bearer Context Request )消息给 eNodeB/HENB ,该消息中携带 ΑΡΝ, PDN Type: PDN Address, EPS Bearer Id, Protocol Configuration Options, SIPTO 激活标志 ( SIPTO Activation Flag )等信息。
此消息是包含在一个 SI— MME control 消息中,即演进的无线接入承载建 立请求( e-RAB Setup Request )或初始上下文建立请求 ( Initial Context Setup Request ) 消息中, 这两个消息均包含 EPS Bearer Identity, EPS Bearer QoS, UE-AMBR, 服务网关上行链路 IP地址(Serving GW UL IP address ), SI隧道 端点标识( Sl-TEID )等参数。其中,当 UE发起的 PDN连接过程,则 SI— MME Control消息为 e-RAB Setu 消息,若 UE是在 Attach过程中建立的 PDN连接, 则 S1 MME Control消息为 Initial Context Setup Request消息。 SIPTO Activation Flag是本发明实施例提出的指示 SIPTO被激活的标识。 有两种指示的方法, 一种指示是若 Activate Default EPS Bearer Context Request 消息中包含有 SIPTO Activation Flag参数, 则指示此对应的 PDN连接的 SIPTO被激活, 当 此消息中没有包含有 SIPTO Activation Flag参数, 则指示此对应的 PDN连接 的 SIPTO被激活。而另一种指示方法是 SIPTO Activation Flag取一个值(如 1 ) 表示此对应的 PDN连接的 SIPTO被激活, 当 SIPTO Activation Flag参数取另 一个值(如 0 ), 则指示此对应的 PDN连接的 SIPTO未被激活。
步骤 7: eNodeB/HENB发送无线资源控制连接重配置 (RRC Connection Reconfiguration ) (其中消息包含参数 EPS无线承载标识 (EPS Radio Bearer Identity ) )消息给 UE, 并且 Activate Default EPS Bearer Context Request消息被 包含在此 RRC消息中被传送给 UE。
步骤 8 : UE 发送无线资源控制连接重配置完成 (RRC Connection Reconfiguration Complete ) 消息给 eNodeB/HENB。
步骤 9: eNodeB/HENB发送 SI接入点响应 ( Sl-AP Response ) 消息给
MME。 此 Sl-AP Response消息包含 eNodeB/HENB分配的 S1-U接口下行 IP 地址与 TEID。 步骤 10: UE发送无线资源控制直接传输( RRC Direct Transfer ) 消息给 eNodeB/HENB, 此消息包含激活默认 EPS 承载上下文接受 (Activate Default EPS Bearer Context Accept ) 消息, 该消息中携带 EPS Bearer Identity, Protocol Configuration Options等信息。 eNodeB/HENB在上行链路非接入层传输( Uplink NAS Transport )消息中前转 Activate Default EPS Bearer Context Accept消息给 需要说明的是, 为了描述的方法, 上面只给出与本发明实施例相关的关 键步骤, 一些与本发明实施例无关的步骤没有被列出, 这些步骤没有给出, 并不影响本发明实施例的使用。
实施例二:
基于本发明实施例方法提出, 当 UE从 UTRAN或 GERAN系统发起建立 一个 PDN连接, SGSN在发送给 UE的 NAS消息 Activate PDP Context Request 中增加一个 SIPTO激活的标识 SIPTO Activation Flag。 当此 SIPTO Activation Flag被包含在消息中或 SIPTO Activation Flag取一个特定值就表明此 PDN连 接的 SIPTO被激活。 如图 4B所示。
步骤 1 : UE发起一个 PDN连接, 则 UE发送激活分组数据协议上下文请 求( Activate PDP Context Request ) 消息给 RNC/BSS/HNB。
步骤 2: SGSN根据 UE在步骤 1中提供的 APN或 Request Type, 及 UE 的签约数据,及 SGSN中的配置的 Policy决定对这个 PDN连接进行 SIPTO的 激活。
SGSN进行网关的选择, 选择的网关还包含 PDN GW或 GGSN的选择, 并且选择一个离 UE在物理上或地址很近的 PDN GW或 GGSN。
若 SGSN选择的是 PDN GW,则 SGSN发送创建会话请求( Create Session Request )消息给 Serving GW; Serving GW发送 Create Default Bearer Request 消息给 PDN GW。
若 SGSN选择的是 GGSN, 则 SGSN发送创建分组数据协议上下文请求 ( Create PDP Context Request ) 消息给 GGSN; 步骤 3:若 SGSN选择的是 PDN GW, PDN GW返回创建会话响应( Create Session Response )消息给 Serving GW。 Serving GW返回创建会话响应( Create Session Response ) 消息给 SGSN。
若 SGSN选择的是 GGSN, 则 GGSN发送创建分组数据协议上下文响应 ( Create PDP Context Response ) 消息给 SGSN。
步骤 4 : UE与 RAN及 SGSN之间的无线接入承载被建立。
步骤 5: SGSN发送激活分组数据协议上下文响应 ( Activate PDP Context Response ) 消息给 RNC/BSS/HNB。
SIPTO Activation Flag是本发明实施例提出的指示 SIPTO被激活的标识。 有两种指示的方法, 一种指示是若 Activate PDP Context Response消息中包含 有 SIPTO Activation Flag参数, 则指示此对应的 PDN连接的 SIPTO被激活, 当此消息中没有包含有 SIPTO Activation Flag参数, 则指示此对应的 PDN连 接的 SIPTO被激活。而另一种指示方法是 SIPTO Activation Flag取一个值(如 1 )表示此对应的 PDN连接的 SIPTO被激活, 当 SIPTO Activation Flag参数 取另一个值(如 0 ), 则指示此对应的 PDN连接的 SIPTO未被激活。
需要说明的是, 为了描述的方法, 上面只给出与本发明实施例相关的关 键步骤, 一些与本发明实施例无关的步骤没有被列出, 这些步骤没有给出, 并不影响本发明实施例的使用。
发明实施例方法二: 当建立或修改一个 EPS Bearer或 PDP Context时, 当 网络激活 SIPTO时,网络需要指示 UE此 EPS Bearer或 PDP Context的 SIPTO 被激活。
实施例三:
基于本发明实施例方法提出, 当 UE位于 E-UTRAN系统时, 建立或修改 一个 EPS Bearer时 , MME在发送给 UE的 NAS消息中增加一个 SIPTO激活 的标识 SIPTO Activation Flag。 当此 SIPTO Activation Flag被包含在消息中或 SIPTO Activation Flag取一个特定值就表明此 EPS Bearer的 SIPTO被激活。
在 EPS系统中, 有两种方式建立一个 EPS Bearer连接, 一个是 UE通过 发送 载资源分配请求 ( Bearer Resource Allocation Request )或 载资源爹改 请求 ( Bearer Resource Modification Request ) 消息而触发, MME向 UE发送 激活专用 EPS 载上下文请求 ( Activate Dedicated EPS Bearer Context Request ), 而另一种是直接通过网络触发 MME 向 UE发送 Activate Dedicated EPS Bearer Context Request。 不管是哪种方法, MME在向 UE发送 Activate Dedicated EPS Bearer Context Request中增加一个 SIPTO Activation Flag参数, 就可指示 UE此 Bearer的 SIPTO是否激活。
另夕卜, MME还可以向 UE发送修改 EPS 承载上下文请求(Modify EPS Bearer Context Request )消息来修改一个 EPS Bearer的月良务质量( QoS )或 TFT 参数,同样,本发明实施例提出 MME在向 UE发送 Modify EPS Bearer Context Request中增加一个 SIPTO Activation Flag参数,就可指示 UE此被修改的 EPS Bearer的 SIPTO是否激活。
实施例四:
基于本发明实施例方法二提出, 当 UE位于 UTRAN/GERAN系统时, 建 立或修改一个 PDP Context时, SGSN在发送给 UE的 NAS消息中增加一个 SIPTO激活的标识 SIPTO Activation Flag„ 当此 SIPTO Activation Flag被包含 在消息中或 SIPTO Activation Flag取一个特定值就表明此 EPS Bearer的 SIPTO 被激活。
在建立一个 PDP Context时, SGSN在发送给 UE的激活分组数据协议上 下文接受( Activate PDP Context Accept )或激活第二个分组数据协议上下文接 受( Activate Secondary PDP Context Accept )的消息中增加一个 SIPTO激活的 标识 SIPTO Activation Flag。 当此 SIPTO Activation Flag被包含在消息中或 SIPTO Activation Flag取一个特定值就表明此 PDP Context的 SIPTO被激活。
在修改一个 PDP Context时, SGSN在发送给 UE的修改分组数据协议上 下文请求 ( Modify PDP Context Request ) (此 PDP Context的修改由 SGSN发 起)或修改分组数据协议上下文接受 (Modify PDP context Accept ) (此 PDP Context 的修改由 UE 发起) 消息中增加一个 SIPTO 激活的标识 SIPTO Activation Flag。 当此 SIPTO Activation Flag 被包含在消息中或 SIPTO Activation Flag取一个特定值就表明此 PDP Context的 SIPTO被激活。
方法三: 当 UE建立一个 PDN连接时, 网络指示此 PDN连接的 SIPTO 被激活时, 则 UE需要将此 SIPTO激活的信息呈现给用户。
呈现的方法有很多种, 如在手机的屏幕上显示一特定的指示; 对于数据 卡, 则可能需要特定的软件指示给用户。
另外, 还有一种呈现方法是, 当 UE在此 PDN连接发起一个业务时, 提 示此 PDN连接是 SIPTO激活, 让用户是否继续使用此 PDN连接来承载此业 务。 若用户选择是, 则继续使用此 PDN连接来承载此业务, 否则, 则让用户 选择其它的 PDN连接来承载此业务。
方法四: 当建立或爹改一个 EPS Bearer或 PDP Context时, 当网络指示此 EPS Bearer或 PDP Context的 SIPTO激活时, 则 UE需要将此 SIPTO激活的 信息呈现给用户。
呈现方法类似如上面的方法, 呈现的方法有很多种, 如在手机的屏幕上 显示一特定的指示; 对于数据卡, 则可能需要特定的软件指示给用户。
另外, 还有一种呈现方法是, 当 UE在此 EPS Bearer或 PDP Context发起 一个业务时, 提示此 PEPS Bearer或 PDP Context是 SIPTO激活, 让用户是否 继续使用此 EPS Bearer或 PDP Context来承载此业务。若用户选择是,则继续 使用此 EPS Bearer或 PDP Context来承载此业务, 否则 ,则让用户选择其它的 EPS Bearer或 PDP Context来承载此业务。
本发明实施例提出的方法是网络通过 NAS消息, 指示用户终端其 SIPTO 被激活, 另外网络也可以通过 S1与 RRC接口消息, 或 Iu接口消息与 RRC 接口消息通知用户终端其对应的 PDN连接或 Bearer的 SIPTO被激活。 在这 种情形下,本发明实施例提出 SIPTO Activation Flag则可以通过 S1与 RRC接 口消息, 或 Iu与 RRC接口消息通知给 UE , 但这需要同时修改两个接口的消 息, 因此过程较为复杂, 但基本方法是一样, 这里就不再给出具体的说明。
