Description
本发明涉及通信领域,具体而言,涉及一种分组交换PS数据业务的处理方法、终端、MME及PGW。
针对***通讯***(the 4th Generation mobile communication technology,简称为4G),第三代合作伙伴计划(3rd Generation Partnership Project,简称为3GPP)标准工作组定义了长期演进(Long Term Evolution,简称为LTE)***无线子***、演进分组域***(Evolved Packet System,简称为EPS)核心网子***。
图1是相关技术中的LTE/EPS***的架构示意图。其中,无线子***LTE部分,主要包括演进的通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network,简称为E-UTRAN)。EPS核心网子***部分,也称为演进的分组核心网(Evolved Packet Core,简称为EPC)。在该***架构下,EPC不仅支持用户从LTE接入,还支持用户从GSM EDGE无线接入网(GSM EDGE radio access network,简称为GERAN)和通用陆地无线接入网(Universal Terrestrial Radio Access Network,简称为UTRAN)的接入。
在EPC分组核心网中,包含归属用户数据服务器(Home Subscriber Server,简称为HSS)、移动性管理单元(Mobility Management Entity,简称为MME)、服务网关(Serving Gateway,简称为S-GW)、分组数据网络网关(PDN Gateway,简称为P-GW)、服务GPRS支持节点(Serving GPRS Support Node,简称为SGSN)和策略与计费规则功能实体(Policy and Charging Enforcement Function,简称为PCRF),其中:
HSS,是用户签约数据的永久存放地点,位于用户签约的归属网;
MME,是用户签约数据在当前网络的存放地点,负责终端到网络的非接入层(Non-Access Stratum,简称为NAS)信令管理、用户空闲模式下的跟踪和寻呼管理功能和承载管理;
S-GW,是核心网到无线***的网关,负责终端到核心网的用户面承载、终端空闲模式下的数据缓存、网络侧发起业务请求的功能、合法窃听和分组数据路由和转发功能;
P-GW,是演进的分组域***(EPS)和该***外部网络的网关,负责终端的IP地址分配、计费功能、分组包过滤、策略应用等功能。
SGSN,是GERAN和UTRAN用户接入EPC网络的业务支持点,功能上与MME类似,负责用户的位置更新、寻呼管理和承载管理等功能。
PCRF,负责向PCEF提供策略控制与计费规则。
在EPS架构下,用户设备(User Equipment,简称为UE)接入到EPS网络后,网络会为UE创建合适的公共数据网(Public Data Network,简称为PDN)连接,并为UE分配互联网协议(Internet Protocol,简称为IP)地址,从而UE可以使用该IP地址发送和接收IP数据包。在LTE/EPS架构下,实现语音业务,需要借助于LTE语音(Voice Over LTE,简称为VoLTE)服务***。典型地,IP多媒体子***(IP Multimedia Subsystem,IMS)提供了基于IP通讯的语音会话、视频通讯、媒体消息等服务,是实现LTE语音服务的首选。并且,在IMS子***上,不仅仅提供可以实现语音会话、视频会话、短消息服务,还可以实现丰富类型的第三方数据类业务,如多方视频共享。
在LTE/EPS***架构下,IMS多媒体子***依赖于支持IMS的特定PDN连接。通常,运营商会定义专用于IMS的特定的APN名称(即“IMS”),来提供服务于IMS的PDN连接。
在相关的EPS技术下,UE初始附着时候,EPC核心网会根据用户签约中的缺省接入点名称(Access Point Name,简称为APN)为UE创建一个缺省的PDN连接。UE可以使用该PDN连接发起上行IP数据传输,也
可以在该PDN连接上接收远端(如,应用服务器)发送的下行IP数据。其后,如果UE根据业务需要,需要创建其他的PDN连接,会根据业务需求使用对应的APN请求创建一个新的PDN连接。在一个PDN连接内,UE或者网络可以创建多个不同的承载(EPS bearer),每个承载具有不同的承载参数,如:服务质量等级(QoS Class Identifier,简称为QCI)、分配和保持优先级(Allocation and Retention Priority,简称为ARP),等等。不同的承载通常应用于不同的数据流,如语音、视频、数据通常会被分配不同的QCI、ARP。
当UE不再需要使用某个PDN连接时,UE可向网络发起去激活PDN连接请求,EPC核心网释放该PDN连接所占用的资源,包括该PDN连接内所有的EPS承载。在需要的时候,EPC核心网同样可以发起PDN连接的去激活。
对终端用户而言,当用户不想继续使用数据业务时,用户可以通过终端操作界面的功能菜单手动关闭数据连接。这通常会触发UE自动发起去激活PDN连接请求,网络因此释放该PDN连接的资源,包括该PDN连接下的所有承载。
然而,这种关闭数据业务使用的方法,过于粗陋,很难满足实施LTE语音后的用户需求。当使用LTE语音业务后,用户希望可以在保留IMS语音业务的同时,关闭普通的数据业务,如Internet访问。但是相关技术中无法实现有选择地关闭部分数据服务的目的。
针对相关技术中存在的上述问题,目前尚未提出有效的解决方案。

在相关技术中,UE请求的承载资源创建和释放的流程示意图如图2所示,
图2是相关技术下,在UE附着过程中和UE附着到网络后,网络为
UE创建和释放承载资源的过程,包括PDN连接、专有承载的创建和释放过程。如图2所示,该流程包括如下步骤:
2A01~2A11,UE请求附着到网络,MME为UE创建缺省PDN连接、缺省承载。
2A01~2A02,UE发送附着请求(Attach Request),该附着请求被eNodeB前转给MME;
2A03,MME向HSS发送位置更新请求(Update Location Request);
2A04,HSS向MME返回位置更新响应(Update Location Response),携带UE签约数据;
2A05,MME根据UE在Attach请求中所携带的APN信息,或MME从HSS收到的UE签约数据中的缺省APN信息,选择SGW/PGW,并向SGW/PGW发送会话创建请求(Create Session Request);
2A06,PGW向PCRF发送IP承载创建请求(IP-CAN Session Establishment Request);

2A10,eNodeB向UE发送RRC重配置请求,根据MME发送的初始上下文建立请求中的无线承载列表,eNodeB为UE配置对应的空口承载;
2A11,UE向eNodeB返回RRC重配置响应;
2A12,eNodeB向MME发送初始上下文建立响应;
2B01~2B06,UE请求创建额外的PDN连接、或请求创建专有承载。
当UE希望发起特定业务,但是没有满足该业务的PDN连接时,UE可以请求创建额外的PDN连接。当满足该业务的PDN连接已经存在,但是没有满足业务的专有承载时,UE可以请求创建专有承载。
2B01,UE发起PDN连接建立请求;

2B04,PCRF向PGW返回IP会话建立响应,携带PCC策略;
2B05,PGW为UE创建承载,向MME返回会话创建响应,携带所创建的EPS承载列表;
2B06,MME向UE返回PDN连接建立响应,其中携带已创建的EPS承载列表;
如果上述2B01~2B06过程中UE发起的是专有承载的创建,则2B01中UE发送的是专有承载创建请求,2B02中MME发送的是承载修改请求,2B03中PGW发送IP会话修改请求,2B04中PCRF返回IP会话修改响应,2B05中PGW返回承载修改响应,2B06中MME返回承载创建响应。
2C01~2C06,UE发起PDN连接释放,或专有承载的释放。当UE判断某个PDN连接不再需要、或某个专有承载不在需要时,可用发起相应的释放流程。在收到UE的PDN连接释放请求后,网络释放该PDN连接的资源,包括该PDN连接下的EPS承载。在收到UE的承载释放请求后,网络释放该EPS承载所占用的资源。
图2所示的关闭数据业务使用的方法,很难满足实施LTE语音后的用户需求。当使用LTE语音业务后,用户希望可以在保留IMS语音业务的同时,关闭普通的数据业务,如Internet访问。但是相关技术中无法实现有选择地关闭部分数据业务的目的。根据该需求,需要提供一种机制,允许有选择地部分关闭业务。很显然,采用现有技术无法实现这一需求。
基于上述考虑,本发明实施例中提供了一种方法,使得终端和网络能
够有选择地部分关闭数据业务,实现允许某些业务允许使用数据连接,某些业务禁止使用数据连接的目的。
针对部分关闭PS数据业务的需求,本发明实施例中提出了一种方法,使得终端可以向网络发送一个简单的PS数据关闭指示,触发网络有选择地释放不需要的PDN连接、EPS承载,或对PDN连接、EPS承载进行标记PS数据关闭,并禁止在被标记的EPS承载上传输数据。下面对本发明进行说明:

在本实施例中提供了一种可以运行于上述移动终端的分组交换PS数据业务的处理方法,图4是根据本发明实施例的分组交换PS数据业务的处理方法的流程图(一),如图4所示,该流程包括如下步骤:
步骤S402,向网络侧网元发送用于请求关闭PS数据业务的分组交换PS数据关闭指示;

步骤S406,根据上述第一EPS承载列表停止进行上述PS数据业务。
其中,执行上述操作的可以是终端(可以简称为UE)。上述的PS数据业务包括EPS承载。停止进行上述PS数据业务包括停止在特定的EPS承载上发起上行数据传输。
通过上述步骤,可以由终端向网络侧发送PS数据关闭指示,从而触发网络侧(可以是一个或多个网络侧的网元)释放不需要数据业务,即,通过上述步骤,可以由网络侧确定需要关闭的数据业务,从而实现了有选择地关闭部分数据服务的目的,简化了终端的实现复杂度。
在一个可选的实施例中,向上述网络侧网元发送用于请求关闭PS数据业务的PS数据关闭指示包括:向移动性管理网元MME发送发送非接入层NAS消息,上述NAS消息中携带上述PS数据关闭指示。在本实施例中,终端在给网络侧网元发送PS数据关闭指示时,可以发送NAS消息,利用该NAS消息携带上述PS数据关闭指示,其中,该NAS消息可以包括但不仅仅限于以下消息之一:跟踪区域更新(Tracking Area Update,简称为TUA)请求、路由区域更新(Routing Area Update,简称为RAU)请
求、服务请求(Service Request)、附着(Attach)请求。其中,无论UE是在连接态(ECM-CONNECTED)还是空闲态(ECM-IDLE),UE均可以使用TAU消息来发送PS数据关闭指示。对应地,如果UE是从UTRAN接入,则UE使用RAU消息来发送PS数据关闭指示。如果UE是在空闲态,则UE可以考虑使用Service Request消息来发送PS数据关闭指示。

EPS承载列表;根据上述第二EPS承载列表恢复进行PS数据业务。在本实施例中,终端在启用PS数据关闭后,当终端希望恢复PS数据传输时,可以向网络侧请求取消PS数据关闭。上述第二响应消息中可以携带一个EPS承载列表,终端可以根据第二响应消息中的EPS承载列表更新自身所保存的EPS承载列表,根据EPS承载列表中信息,PS数据关闭已被停用,则UE不会继续阻止在某个承载上发起上行数据。
在本实施例中还提供了一种分组交换PS数据业务的处理方法,图5是根据本发明实施例的分组交换PS数据业务的处理方法的流程图(二),如图5所示,该流程包括如下步骤:

下面结合具体实施例对本发明进行说明:
实施例一:
图7是本发明的实施例一,UE在附着到网络后,向MME发送NAS请求,携带PS数据关闭指示。
图7具有如下步骤:
7A01~7A08,UE请求附着到网络,MME从HSS获取UE签约数据,
为UE创建缺省PDN连接。下面对各步骤进行说明:
7A01,UE向MME发送附着请求(Attach Request);
7A02,MME向HSS发送位置更新请求(Update Location Request);
7A03,HSS向MME返回位置更新响应(Update Location Response),携带UE签约数据;
在本步骤中,归属网运营商可能在UE签约数据中设置了关于PS数据关闭的配置信息,如:
-是否允许该UE启用PS数据关闭特性;
-哪些APN允许/不允许启用PS数据关闭特性;
-哪些业务允许/不允许启用PS数据关闭特性;
其中,运营商可根据运营策略,对某些特殊业务设置免于PS数据关闭:IMS语音业务、IMS视频会话业务、IMS短消息业务、等等;
7A04,MME根据UE在Attach请求中所携带的APN信息,或MME从HSS收到的UE签约数据中的缺省APN信息,选择SGW/PGW,并向SGW/PGW发送会话创建请求(Create Session Request);
7A05,PGW向PCRF发送IP承载创建请求(IP-CAN Session Establishment Request);
7A06,PCRF向PGW返回IP承载创建响应(IP-CAN Session Establishment Response),携带PCC策略;
7A07,SGW/PGW向MME返回会话创建响应(Create Session Response),携带EPS承载列表;
7A08,MME向UE返回附着响应,携带EPS承载列表;
7B01~7B07,其后,当UE判断需要关闭PS数据业务时,UE在NAS消息中向网络发送PS数据关闭指示,触发网络执行相应处理。包括:
7B01,UE向MME发送NAS消息,携带PS数据关闭指示;
在本步骤中,UE可以使用TAU消息、或Service Request(服务请求)消息,来携带PS数据关闭指示。无论UE是在连接态(ECM-CONNECTED)还是空闲态(ECM-IDLE),UE均可以使用TAU消息来发送PS数据关闭指示。对应地,如果UE是从UTRAN接入,则UE使用RAU消息来发送PS数据关闭指示。如果UE是在空闲态,则UE可以考虑使用Service Request消息来发送PS数据关闭指示。当然,UE也可以使用其他合适的NAS消息向MME发送PS数据关闭指示。
7B02,当MME收到UE的NAS消息,其中携带PS数据关闭指示,MME将PS数据关闭指示前转给SGW/PGW处理,或额外地判断并处理PDN连接;
在本步骤中,如果根据本地策略,MME不参与处理PS数据关闭指示,则MME将PS数据关闭指示前转给SGW/PGW处理。在此时,即使MME从HSS获取的UE签约数据中包含PS数据关闭的配置信息,MME也将忽略该信息。
或者,在MME向SGW/PGW前转PS数据关闭指示之前,MME先对PDN连接进行判断处理,MME可采用如下方式进行判断:
MME判断某一PDN连接是否可以释放:如果MME判断某一PDN连接下所有承载均可以释放,即可释放该PDN连接,则MME可发起对该PDN连接的PDN连接释放过程;
MME判断某一PDN连接是否启用PS数据关闭:如果某PDN连接不可以被释放,则MME判断是否对将PDN连接标记为PS数据关闭。MME可根据如下信息之一或组合进行判断:本地网络策略、(签约数据中的)PS数据关闭配置信息、(该PDN连接使用的)APN、等。若MME判断对某一PDN连接启用PS数据关闭,则MME在该PDN连接上下文中标记PS数据关闭指示。
MME判断某一PDN连接下EPS承载是否启用PS数据关闭:当判断某PDN连接启用PS数据关闭时,MME可进一步判断该PDN连接下的
EPS承载是否启用PS数据关闭。MME可根据如下信息之一或组合进行判断:本地网络策略、(签约数据中的)PS数据关闭配置信息、(该PDN连接使用的)APN、QCI、ARP、等。若MME判断某一EPS承载启用PS数据关闭,则MME在该EPS承载上下文中标记PS数据关闭指示。
7B03,MME向SGW/PGW发起会话修改请求,携带PS数据关闭指示;
7B04,当PGW收到会话修改请求,其中携带PS数据关闭指示,PGW判断PDN连接/EPS承载是否应被释放、或是否启用PS数据关闭;
在本步骤中,PGW可以采用如下方式的组合进行判断:
PGW判断某一承载是否应被释放:PGW根据如下信息之一或组合,判断某一承载是否应该被释放:本地策略、APN、QCI、ARP等。
PGW判断当前PDN连接是否应被释放,若该PDN连接下所有承载均应被释放,则该PDN连接应被释放;
PGW判断某一承载是否应启用PS数据关闭:PGW根据如下信息之一或组合,判断某一承载是否可启用PS数据关闭特性:本地策略、APN、QCI、ARP等;
当PGW判断某一承载应启用PS数据关闭时,PGW采用如下方式之一对承载进行标记:
PGW对该EPS承载标记PS数据关闭指示。根据该PS数据关闭指示,UE阻止在该承载上的上行数据传输,PGW阻止在该承载上的下行数据传输。
PGW对该EPS承载设置一个特殊的承载过滤模板(Traffic Filter Template,简称为TFT),通过该特殊的TFT的设置,UE的上行数据将无法匹配到该EPS承载,达到阻止UE在该承载上发起上行数据传输。通过该TFT的设置,PGW的下行数据无法匹配到该EPS承载,达到阻止PGW在该承载上发起下行数据传输。
若PGW认为必须由PCRF来决定某一承载是否启用PS数据关闭,则PGW向PCRF发送IP会话修改请求,携带PS数据关闭指示;
7B05,PGW向PCRF发送IP会话修改请求,携带PS数据关闭指示;
7B06,PCRF对IP承载,判断是否允许启用PS数据关闭;
当PCRF收到PGW发送的IP会话修改请求后,PCRF采用如下方式判断对指定的IP承载是否启用PS数据关闭特性:
PCRF根据本地策略或从SPR获取的签约数据,判断指定IP承载是否启用PS数据关闭;或者,
PCRF和应用功能(Application Function,简称为AF)执行交互,根据交互结果判断指定IP承载是否启用PS数据关闭;
当PCRF对某一IP承载判断可启用PS数据关闭时,PCRF对该承载采用如下方式进行标记:
PCRF对该IP承载标记PS数据关闭指示;或者,
PCRF对该IP承载设置一个特殊的承载过滤模板(Traffic Filter Template,简称为TFT),通过该TFT的设置,达到阻止UE在该承载上发起上行数据传输,阻止PGW在该承载上发起下行数据传输。
7B07,PCRF向PGW返回IP会话修改响应;
在本步骤中,PCRF在IP承载信息中,携带PS数据关闭指示,或携带特殊的TFT模板;
7B08,PGW对PDN连接和EPS承载,标记PS数据关闭指示;
根据前述7B04步骤中PGW的处理,以及7B07步骤中PCRF的返回信息,PGW对PDN连接和EPS承载进行标记:
PGW在PDN连接上下文中,设置PS数据关闭指示;
PGW对EPS承载标记PS数据关闭指示。或者,对EPS承载设置特殊的TFT模板,达到禁止上下行数据传输的目的;
对于某些特殊承载,根据运营商策略、或签约数据的指示,可能不允许其启用PS数据关闭,则PGW对该承载,不标记PS关闭指示,不设置特殊的TFT模板。
7B09,PGW向MME发送会话修改响应消息,携带EPS承载列表;
7B10,MME根据PGW返回的会话修改响应消息,对PDN连接、EPS承载进行标记;
MME根据PGW所返回的信息,对PDN连接进行标记,即:在PDN连接上下文中标记PS数据关闭指示。
MME根据PGW所返回的EPS承载列表,在MME上存储EPS承载上下文。根据前述步骤中的处理,EPS列表中EPS承载,可能未被做任何标记,可能被标记了PS数据关闭指示,可能被设置了特殊的TFT模板。
7B11,MME向UE返回NAS响应消息,携带EPS承载列表;
当UE收到EPS承载列表后,更新UE自身所保持的EPS承载上下文。若某一EPS承载被标记为PS数据关闭,则UE应自行阻止在该EPS承载上发起上行数据传输。若某一EPS承载被设置了特殊的TFT模板,根据该TFT模板,UE无法将上行数据匹配到该承载上,达到UE自行阻止在该承载上发起上行数据传输的目的。
需要说明的是,在图7所示的实施例中,MME、PGW均可能执行是否启用PS数据关闭的相关判断,根据运营商本地策略,该判断可以相互叠加和组合,最终判断结果由多方判断结果叠加形成,如:
MME不执行判断,仅PGW执行判断;
MME、PGW均执行判断,MME以PGW判断结果为最终判断;
MME不执行判断,PGW执行判断,PGW可请求PCRF协助判断。
实施例二:
图8是本发明的实施例二,在启用PS数据关闭后,如果UE希望恢
复PS数据传输,则UE向网络请求取消PS数据关闭。
图8具有如下步骤:
8A01,同图7中步骤所示,UE附着到网络,其后UE请求启用PS数据关闭;
8B01~8B06,其后,UE希望恢复PS数据传输,向网络请求PS数据开启。包括:
8B01,UE向MME发送NAS消息,携带PS数据开启指示;
在本步骤中,UE可以使用TAU/RAU、Service Request等NAS消息来发送PS数据开启指示。
8B02,MME向SGW/PGW发送会话修改请求,携带PS数据开启指示;
MME向SGW/PGW发送会话修改请求,携带PS数据开启指示,可以是无条件的,即MME向所有PDN连接的SGW/PGW均发送PS数据开启指示。或者,MME检查UE的PDN连接,若某PDN连接被标记为PS数据关闭,则MME向对应的SGW/PGW发送会话修改请求,携带PS数据开启指示。
当PGW收到MME发送的会话修改请求后,PGW检查PDN连接上下文、以及EPS承载,执行如下操作:
如果PDN连接上下文中被标记了PS数据关闭指示,则PGW移除PDN连接上下文中的该指示;
如果EPS承载被标记了PS数据关闭指示,则移除该承载的PS数据关闭指示;
如果EPS承载被设置了特殊的TFT模板,该TFT模板阻止该承载的上下行数据,则PGW移除该特殊的TFT模板,并为该承载配置正常的TFT模板。
当PGW需要向PCRF通知PS数据开启,则PGW向PCRF发送IP
会话修改请求,携带PS数据开启指示。
8B03,PGW向PCRF发送IP会话修改请求,携带PS数据开启指示;
当PCRF收到PGW的IP会话修改请求后,若某承载先前具有PS数据关闭指示,则移除该PS数据关闭指示。若某承载被设置了特殊的TFT模板,则移除该特殊TFT模板,并为该承载配置正常的TFT模板。
8B04,PCRF向PGW发送IP会话修改响应,携带IP承载信息;
8B05,PGW移除PDN连接、EPS承载中的PS数据关闭指示;
在本步骤中,PGW将PDN连接上下文中的PS数据关闭指示移除。并且,根据PCRF返回的EPS承载列表,更新PGW本地所保存的EPS承载上下文。
8B06,SGW/PGW向MME发送会话修改响应,携带EPS承载列表;
8B07,MME移除PDN连接、EPS承载中的PS数据关闭指示;
在本步骤中,MME将PDN连接上下文中的PS数据关闭指示移除。并且,根据SGW/PGW返回的EPS承载列表,更新MME本地所保存的EPS承载上下文。
8B08,MME向UE返回NAS响应消息,携带EPS承载列表。
UE根据MME所返回的NAS响应消息,更新UE自身所保存的EPS承载列表。根据EPS承载列表中信息,PS数据关闭已被停用,则UE不会继续阻止在某个承载上发起上行数据。
实施例三:
图9是本发明的实施例三,在请求附着到网络时,UE同事携带启用PS数据关闭的指示,图9具有如下步骤:
901,UE向MME发送附着请求,携带PS数据关闭指示;
902,MME向HSS发送位置更新请求;
903,HSS向MME返回位置更新响应,携带UE签约数据;
在本步骤中,当MME获取UE签约数据后,检查签约数据中是否包含PS数据关闭配置信息,如果不包含PS数据关闭配置信息,则MME不能为UE启用PS数据关闭特性。
904,MME选择SGW/PGW,并向SGW/PGW发送会话创建请求,携带PS数据关闭指示;
905,PGW向PCRF发送IP承载创建请求,携带PS数据关闭指示;
906,PCRF向PGW返回IP承载创建响应,包含计费和控制策略;
参考前述流程,PCRF对所请求创建的承载,判断是否允许启用PS数据关闭,从而对该承载标记PS数据关闭指示,或该承载设置特殊TFT模板。
907,PGW对PDN连接、EPS承载进行标记;
参考前述流程,PGW根据自身判断、以及PCRF所返回的IP会话创建响应,对PDN连接、EPS承载进行标记,即对PDN连接、EPS承载标记PS数据关闭指示,或对EPS承载设置特殊TFT。

在EPS承载列表中,其中某些承载被标记PS数据关闭指示,或被设置特殊TFT模板。
909,MME对PDN连接、EPS承载进行标记;
参考前述流程,MME对PDN连接、EPS承载进行标记,即标记PS数据关闭指示。
910,MME向UE返回附着响应,携带EPS承载列表;
若EPS承载列表中某承载被标记了PS数据关闭指示,或被设置了特殊TFT模板,则UE需自行阻止在该承载上发起的上行数据传输。
在上述实施例所示的流程中,当UE希望部分关闭数据业务时,UE向网络发送NAS消息,携带PS数据关闭指示,从而触发网络对UE的PDN
连接、EPS承载进行判断和处理,对PDN连接、或EPS承载标记PS数据关闭指示,或对EPS承载设置特殊的TFT模板。当UE收到网络返回的EPS列表时,根据EPS承载上的PS数据关闭指示,或根据EPS承载所设置的特殊TFT模板,UE自行阻止上行数据传输。
使用本发明实施例中所述的方法,UE无需针对每个PDN连接、EPS承载进行判断,仅需发送单一的PS数据关闭指示给网络,由网络来处理对PDN连接、对EPS承载进行判断的复杂性,从而很大程度上简化了UE的实现复杂度。
