Description

承载处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种承载处理方法及装置。
背景技术
本地互联网接入(Local IP Access，简称为LIPA)是一种允许用户设备(User Equipment，简称为“UE”)通过演进型家庭基站(evolved Home NodeB，简称为eHNB)接入到本地网络(家庭或者企业网络)的技术。接入HeNB的UE能够通过本地网关(Local Gateway，简称为LGW)访问本地网络，并且用户数据无需流经运营商核心网。如图5所示为根据相关技术的本地家庭基站网络示意图。
在第三代移动通信标准化组织(3rd Generation Partnership Project，简称为3GPP)R10阶段，HeNB与LGW部署在同一个物理实体上，并且不支持LIPA连接的移动性，即当处于LIPA连接态的UE移出HeNB覆盖区域时，LIPA承载一般会被先释放掉再允许UE切换到其他目标基站。
在3GPP R11阶段，HeNB与LGW可以是分别独立的物理实体，支持LIPA连接在本地家庭基站网络(Local H(e)NB Network，简称为LHN)内的连续性。一个LHN由一组HeNB组成，这些HeNB可以通过一个或多个LGW得到本地网络的IP连接。一个HeNB只能属于一个LHN；一个LGW也只能属于一个LHN；当UE在同一个LHN下的HeNB之间移动时，需要支持LIPA连接的连续性，此时要求LIPA连接的LGW不改变。
目前的LIPA移动性控制主要在HeNB网关(GateWay，简称为GW)或者移动性管理实体(Mobility Management Entity，简称为MME)，缺点是不能提早进行移动性决策，需要收到切换请求消息才能判决，而且无法对X2链路的切换请求进行移动性控制。
针对相关技术中，不能提早进行移动性决策并且无法对X2链路的切换请求进行移动性控制的问题，还未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种承载处理方法，图1是根据本发明实施例的承载处理方法的流程图，如图1所示，该流程包括如下步骤：
步骤S102，源基站获取目标基站的LIPA能力信息；
步骤S104，源基站根据LIPA能力信息判断目标基站是否保持终端已激活的LIPA承载；
步骤S106，源基站根据判断结果对LIPA承载进行管理。
通过上述步骤，源基站通过判断其获取到的目标基站的LIPA能力信息是否保持终端已激活的LIPA承载，进而根据判断结果对LIPA承载进行管理，相对于现有技术中只有通过源基站的上层HeNB GW或者MME通过获取切换请求才能对LIPA的移动性进行控制，不能提早进行移动性决策，上述步骤解决了现有技术中不能提早进行移动性决策并且无法对X2链路的切换请求进行移动性控制的问题，进而达到了节省资源消耗和信令开销的效果。其中目标基站可以但不限于是源基站的邻区基站。
上述步骤S106涉及到由源基站对LIPA承载进行管理，需要说明的是，源基站可以通过多种方式管理LIPA承载，下面对此进行举例说明。在一个优选实施例中，源基站根据LIPA能力信息判断目标基站不支持终端已激活的LIPA承载的情况下，且终 端还支持非LIPA承载，例如公共承载时，源基站释放LIPA承载，从而节省资源消耗和信令开销。在另一个优选实施例中，源基站根据LIPA能力信息判断目标基站不保持终端已激活的LIPA承载的情况下，且终端仅支持LIPA承载时，源基站可以直接选择最优移动性算法，通知终端移动到目标基站。在另一优选实施例中，在确定目标基站支持终端已激活的LIPA承载的情况下，源基站通知终端通过LIPA承载切换至目标基站。
源基站对LIPA承载进行管理的最终目的在于实现终端成功切换至目标基站，在一个优选实施例中，源基站释放LIPA承载之后，终端通过非LIPA承载切换至目标基站，完成终端从源基站到目标基站的切换。
上述步骤S102中涉及到源基站获取目标基站的本地互联网协议接入LIPA能力信息，源基站可以通过多种方式获取目标基站的LIPA能力信息，在一个优选实施例中，源基站获取目标基站的LIPA能力信息的方式包括以下至少之一：通过嗅探功能实体获取LIPA能力信息；通过终端上报的针对目标基站的测量报告获取该LIPA能力信息；通过长期演进LTE协议中的X2接口获取LIPA能力信息。源基站获取目标基站的LIPA能力信息的方式可以根据实际情况灵活进行选择。
在一个优选实施例中，源基站获取目标基站的该LIPA能力信息具体包括获取目标基站所在本地网络的标识、目标基站所连接的本地网关LGW的标识、目标基站所连接的LGW的地址。
步骤S104中涉及到源基站根据LIPA能力信息判断目标基站是否保持终端已激活的LIPA承载，在一个优选实施例中，在以下至少之一情况下，确定目标基站保持终端已激活的LIPA承载：源基站的本地网络标识和目标基站所在本地网络的标识一致、源基站所连接的LGW的标识和目标基站所连接的LGW的标识一致、源基站所连接的LGW的地址和目标基站所连接的LGW的地址一致；否则，确定目标基站不保持终端已激活的LIPA承载。
在本实施例中还提供了一种承载处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图2是根据本发明实施例的承载处理装的结构框图，如图2所示，该装置应用于源基站，包括：获取模块22，设置为获取目标基站的LIPA能力信息；判断模块24， 设置为根据LIPA能力信息判断目标基站是否保持终端已激活的LIPA承载；管理模块26，设置为根据判断结果对LIPA承载进行管理。
图3是根据本发明实施例的承载处理装的结构框图一，如图3所示，管理模块26包括：释放单元262，设置为在判断结果为否的情况下，且终端还支持非LIPA承载时，释放LIPA承载；第一通知单元264，设置为在判断结果为否的情况下，且终端仅支持LIPA承载时，通知终端移动到目标基站。
图4是根据本发明实施例的承载处理装的结构框图二，如图4所示，管理模块26还包括：第二通知单元266，设置为在判断结果为是的情况下，通知终端通过LIPA承载切换至目标基站。
针对相关技术中存在的上述问题，下面结合优选实施例进行说明，本优选实施例结合了上述实施例及其优选实施方式。
本优选实施例提供了一种支持LIPA移动性的承载管理的方法和装置，用以在确认LIPA移动性不能保持时去激活LIPA承载，并尽可能快速地通知UE移动到目标基站。
本优选实施例提供的一种处理本地IP接入LIPA移动时承载管理的方法，包括：
源侧HeNB基站确定需要切换的UE已激活LIPA承载时，根据已收集的邻区LIPA能力支持信息，判断UE已激活的LIPA承载在进行切换后是否能够保持；
所述源侧HeNB在确定所述LIPA承载在进行切换后不能保持后，释放所述LIPA承载。如果该UE只有LIPA承载，则源侧HeNB可以直接选择(除切换以外的)最优移动性算法，直接通知UE移动到目标基站。
本优选实施例提供一种支持LIPA移动性的承载管理的装置，包括：
接收模块(相当于上述获取模块22)，HeNB可以在无线侧空口通过嗅探器(sniffer)或类似的嗅探功能，获取到邻区基站的LIPA支持能力信息；测量报告中如果包含邻区基站的LIPA支持能力信息，HeNB可以在接收测量报告时收集该信息；HeNB也可以通过X2接口(如果X2接口存在)获取到邻区基站的LIPA支持能力信息；
判断模块(相当于上述判断模块24)，源侧HeNB确定需要切换的UE已激活LIPA承载时，判断UE已激活的LIPA承载切换到目标基站后是否能够保持；
释放模块(相当于上述释放单元262)，源侧HeNB在确定所述LIPA承载在进行切换后不能保持后，释放所述LIPA承载。如果该UE只有LIPA承载，则源侧HeNB可以直接选择(除切换以外的)最优移动性算法，直接通知UE移动到目标基站。
该方法和装置，可以解决三类问题：
1源侧HeNB可以在X2切换场景下进行LIPA切换决策，其他移动性控制点(HeNB GW或者MME等)无此能力；
2源侧HeNB决策需要发起LIPA承载释放，就无需转由上层控制点(HeNB GW或者MME等)决策，能够减少信令消耗，并且加快承载释放；
3源侧HeNB认为无法切换，所有承载必须释放，则可以快速选取其他最优移动性策略，将UE移动到目标端，如果经由一次切换预备过程再去决策，则多了资源消耗和信令开销；
本优选实施例的技术方案可以应用于各种通信系统，例如：通用分组无线业务(General Packet Radio Service，简称为GPRS)、长期演进(Long Term Evolution，简称为LTE)系统、LTE频分双工(Frequency Division Duplex，简称为FDD)系统、LTE时分双工(Time Division Duplex，简称为TDD)、通用移动通信系统(Universal Mobile Telecommunication System，简称为UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为WiMAX)通信系统、码分多址(Code Division Multiple Access，简称为CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为WCDMA)系统、全球移动通讯(Global System of Mobile communication，简称为GSM)系统等。
在本优选实施例中，用户设备(User Equipment，简称为UE)可称之为终端(Terminal)、移动台(Mobile Station，简称为MS)、移动终端(Mobile Terminal)等，该UE可以经无线接入网(Radio Access Network，简称为RAN)与核心网进行通信，例如，UE可以是移动电话、具有移动终端的计算机、便携式/袖珍式/手持式/计算机内置/车载的移动装置，它们与无线接入网交换语音和/或数据。
应理解，在本发明实施例中，处理LIPA移动性承载的装置可以是LTE中的演进型基站(Envolved Node B，简称为ENB或e-NodeB)，也可以是WCDMA中的基站(NodeB，简称为NB)，还可以是GSM或CDMA中的基站(Base Transceiver Station，简称为BTS)，本优选实施例并不限定。
本优选实施例可以应用于异构网络，并且家庭基站HeNB可以为宏小区中的宏基站或微小区中的微基站。但为描述方便，下述实施例统一以家庭基站HeNB和用户设备UE为例进行说明。另外，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
为使本优选实施例的目的、技术方案更加清楚，下面将结合附图对本优选实施例的实施方式作进一步地详细描述。
图6是根据本发明优选实施例的支持LIPA移动性的承载管理的方法流程示意图一，如图6所示，本优选实施例支持LIPA移动性的承载管理的方法包括下列步骤：
步骤S602，源侧HeNB收集邻区基站的LIPA支持能力信息；
步骤S604，源侧HeNB确认UE有激活的LIPA承载并且将要切换，判断LIPA承载在切换后是否能够保持；
步骤S606，源侧HeNB确定UE的LIPA承载在进行切换后不能保持并且UE还有其它非LIPA承载，则先释放所述LIPA承载，然后将只包含非LIPA承载的切换请求消息发送给目标基站。如果该UE只有LIPA承载，则源侧HeNB可以直接选择(除切换以外的)最优移动算法，直接通知UE移动到目标基站。
在实施中，源侧HeNB可以有多种方式收集邻区基站的LIPA支持能力信息。
方式1：源侧HeNB通过sniffer或者其他嗅探功能获取邻区基站的LIPA能力信息；
方式2：源侧HeNB从UE上报的邻区测量报告信息中获取邻区基站的LIPA能力信息；
方式3：源侧HeNB通过LTE协议中的X2接口(或者其他基站间接口)获取邻区基站的LIPA能力信息；
UE接入时或者ERAB动态建立时的上下文中包含LIPA承载信息，当源侧HeNB判断出UE符合切换条件时，并且知道此时UE包含LIPA承载，再去判断邻区基站的LIPA支持能力信息。
邻区基站的LIPA支持能力信息是指邻区基站所在的本地网络的标识、邻区基站所连接的LGW的标识、邻区基站所连接的LGW的地址中的至少一个。源侧HeNB 获取到这些信息中的至少一个，表明邻区基站支持LIPA。如果邻区不支持LIPA，则不会将这些信息中的一个或多个广播出来或者通过接口传递给请求基站。
在步骤S606中，源侧HeNB判断目标基站是否支持LIPA承载的移动性，可以包括确定目标基站是否与本基站的本地网络标识相同。如果相同，则目标基站支持该LIPA承载，否则不支持；还可以包括确定目标基站连接的LGW的标识或者地址，如果与本基站连接的LGW的标识或者地址相同，则目标基站支持该LIPA承载，否则源侧HeNB也不确定，交由HeNB GW和MME等核心网节点做进一步判断；如果确定收集的目标基站信息中没有LIPA相关上述标识，则源侧HeNB确认目标基站不支持LIPA承载的移动性。
源侧HeNB确定所述UE的LIPA承载在进行切换后不能保持并且UE还有其它非LIPA承载，则先释放所述LIPA承载，然后将只包含非LIPA承载的切换请求消息发送给目标基站。源侧HeNB如果能够及时感知并触发LIPA承载释放，该释放会更快速。如果由HeNB GW或者MME等核心网结点感知LIPA承载切换后不可持续，再去触发LIPA承载释放则相对较慢，也增加了信令开销和资源浪费。
源侧HeNB确定所述UE的LIPA承载在进行切换后不能保持并且UE只有LIPA承载，则源侧HeNB可以直接选择(除切换以外的)最优移动性算法，直接通知UE移动到目标基站。同理，如果该判决由HeNB GW或者MME等核心网结点完成，也会延迟UE的移动，并且增加了信令开销和资源浪费。
图7是根据本发明优选实施例的支持LIPA移动性的承载管理的方法流程示意图二，如图7所示，该流程包括如下步骤：
步骤S702，源侧HeNB收集好邻区基站的LIPA支持能力，UE已激活了LIPA承载，此时判断出UE可以向邻区(基站)切换；
步骤S704，源侧HeNB根据收集的邻区(基站)LIPA支持能力，判断邻区(基站)是否可以接纳LIPA承载，在判断结果为是的情况下，执行步骤S706，在判断结果为否的情况下，执行步骤S708；
步骤S706，源侧HeNB向目标邻区(基站)发起切换请求，请求中包含LIPA承载和(或者)非LIPA承载；
步骤S708，判断是否只有LIPA承载，在判断结果为是的情况下，执行步骤S710，在判断结果为否的情况下，执行步骤S712；
步骤S710，源侧HeNB选择(除切换外的)最佳移动性算法将UE移动到目标基站；
步骤S712，源侧HeNB发起将LIPA承载释放掉，同时向目标邻区(基站)发起切换请求。
上文中图6至图7，详细描述了根据本发明优选实施例的LIPA移动性承载管理的方法，下面将结合图8至图11，详细描述根据本发明优选实施例的支持LIPA移动性的承载管理装置。
图8至图10示出了根据本发明实施例的承载管理装置收集邻区LIPA能力的3种方法的示意图。
图8是根据本发明优选实施例的处理LIPA承载的设备收集邻区LIPA能力方法1示意图，如图8所示，该承载管理装置包括一个：邻区LIPA能力收集模块(相当于上述获取模块22)。邻区装置可以将自己的LIPA支持能力在广播消息中发送出来，源侧装置可以在无线侧通过sniffer或者其他嗅探功能将邻区的LIPA支持能力获取到。同理邻区装置也可以获取到源侧装置的LIPA能力。
图9是根据本发明优选实施例的处理LIPA承载的设备收集邻区LIPA能力方法2示意图，如图9所示，该承载管理装置包括一个：邻区LIPA能力收集模块(相当于上述获取模块22)。UE的测量报告信息中包含邻区的LIPA支持能力，源侧HeNB获取后将其保存。
图10是根据本发明优选实施例的处理LIPA承载的设备收集邻区LIPA能力方法3示意图，如图10所示，该承载管理装置包括一个：邻区LIPA能力收集模块(相当于上述获取模块22)。承载管理装置如果想请求对端装置的LIPA支持能力信息，可以通过LTE协议中的X2接口(或者其他系统的类似接口)向对端发送LIPA能力请求消息，对端给予应答消息，消息中如果包含对端装置所在的本地网标识、连接的LGW的标识、连接的LGW的地址中的至少一个，则表明对端装置支持LIPA能力信息，否则表明不支持。请求端的承载管理装置将邻区LIPA支持能力信息保存。
图11是根据本发明优选实施例的处理LIPA承载的设备处理移动性时示意图，如图11示出了支持LIPA移动性的承载管理的装置，该装置包含4个模块：1)邻区LIPA能力收集模块；2)判断模块；3)释放模块；4)移动性模块；
邻区LIPA能力收集模块主要是通过上文提到的方法收集邻区的LIPA支持能力，为判断模块提供数据支持；
判断模块发现该UE持有激活的LIPA承载，且满足切换发起条件，通过比较邻区与本基站的LIPA支持能力，判断UE移动后是否LIPA承载可以继续保持；
当判断模块发现UE的LIPA承载移动后不能保持，且UE还有其他非LIPA承载，会通知释放模块发起LIPA承载的释放，释放模块会执行该过程；
当判断模块发现UE的LIPA承载移动后不能保持，且UE只有LIPA承载，会通知移动性模块采取其他方法将UE移动到目标基站，移动性模块会选用除切换外的最优移动性方法执行该过程。
综上所述，本发明实施例提供了一种支持LIPA移动性早期决策，并且支持X2口切换决策的方案。
