Description

LIPA会话的识别方法、设备、系统及计算机存储介质 技术领域
本发明涉及通信中的本地因特网协议接入(LIPA，Local IP Access)会话识别技术，尤其涉及一种LIPA会话的识别方法、设备及系统。
背景技术
第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)演进的分组系统(EPS，Evolved Packet System)，由演进的通用移动通信系统陆地无线接入网(E-UTRAN，Evolved Universal Terrestrial Radio Access Network)、移动性管理实体(MME，Mobility Management Entity)、服务网关(SGW，Serving Gateway)、分组数据网网关(P-GW，Packet Data Network Gateway)、归属用户服务器(HSS，Home Subscriber Server)、3GPP的认证授权计费(AAA，Authentication、Authorization and Accounting)服务器、策略和计费规则功能(PCRF，Policy and Charging Rules Function)实体及其他支撑节点组成。
在无线侧网元如演进基站(eNodeB)、家庭基站(HNB/HeNB)具备本地IP访问能力、且用户签约允许本地IP访问的条件下，可实现终端对家用网络其他IP设备、或互联网络的本地接入。通常，可以通过增设本地网关(LGW，Local Gateway)提供对本地IP访问技术的有力支持，LGW可以与无线侧网元进行合设，这样，终端就可以经由单独设置的LGW、或设置于无线侧网元中的LGW，实现对本地IP网络中其他IP设备的访问、或互联网的本地接入。
在第四代(4G)移动通信网络中，本地LIPA技术最初是基于家庭基站(HeNB)网络提出的，LIPA技术的含义是用户的业务流数据直接从HeNB 进行接入，不经过运营商的核心网络，也就是说，从HeNB接入的业务流数据直接从HeNB就分流出去了，从而减轻了核心网络的负荷和传输成本。
LIPA技术是对HeNB功能的增强，允许终端通过HeNB访问家庭/企业内部的IP资源，这为运营商基于HeNB开发更多的家庭/企业特色的应用提供了可能；并且，对于没有Wi-Fi能力的终端可以做到类似本地Wi-Fi访问的效果；同时，可以联合使用LIPA技术和Wi-Fi技术，并结合一些新型的流移动性技术，能够提升用户的体验。
在LIPA公用数据网(PDN，Public Data Network)连接技术中，LGW取代了分组数据网网关(PGW，Packet data network GateWay)，LGW可以与HeNB集成在一起，实现用户的业务流数据直接从HeNB进行接入，不经过核心网的PGW；其中，所涉及的网元包括HeNB、MME、SGW以及LGW。
发明人在实现本发明的过程中，发现现有LIPA PDN会话连接技术至少存在以下缺陷：
现有LIPA PDN连接技术中，由于SGW无法识别出LIPA PDN会话，因此，SGW无法针对LIPA PDN会话和非LIPA PDN会话，进行不同的计费策略和/或业务策略控制。

具体实施方式
目前LIPA PDN会话的连接建立流程，如图1所示，包括如下步骤：
步骤S100，用户设备(UE)向无线侧网元发送附着请求，所述无线侧网元接收到附着请求后，将LGW的IP地址携带于初始UE消息中发送给 MME；
步骤S101，MME接收到初始UE消息时，向HSS发送位置更新请求，获取LIPA签约信息；
步骤S102，MME通过本地解析或者域名系统(DNS，Domain Name System)解析查找SGW的IP地址，并向SGW发送创建会话请求，所述创建会话请求中携带有LGW的IP地址；
步骤S103，SGW接收到所述创建会话请求时，转发所述创建会话请求给LGW；
步骤S104，LGW接收到创建会话请求时，发送创建会话响应给SGW；
步骤S105，SGW接收到创建会话响应时，将所述创建会话响应转发给MME，所述创建会话响应中携带有用户面IP地址，所述用户面IP地址包括LGW的隧道标识TEIDU、SGW的IP地址和隧道标识TEIDU；
步骤S106，MME接收到创建会话响应时，发送初始上下文建立请求给无线侧网元，所述初始上下文建立请求中携带有用户面IP地址，用于指示无线侧网元根据所述用户面IP地址与LGW建立直接用户面通道，通过所述用户面通道与LGW互相传递上下行数据包。
但是，上述过程中SGW无法识别出LIPA会话，因此，在本发明实施例中，可以通过MME发送的创建会话请求携带LIPA信息给SGW，或者通过LGW发送的创建会话响应携带LIPA信息给SGW，这样，可使所述SGW能够根据所述LIPA信息识别本次会话为LIPA会话，并针对所述LIPA会话进行计费策略和/或业务策略控制，从而能够针对LIPA会话和非LIPA会话进行不同的计费策略和/或业务策略控制。
这里，所述创建会话请求中携带的LIPA信息包括LIPA标识和/或标识LIPA的特定计费特性参数；所述创建会话响应中携带的LIPA信息包括LIPA标识。
具体地，通过MME发送的创建会话请求携带LIPA信息给SGW的场景下，在UE仅签约LIPA属性时，在MME发送的创建会话请求中携带新增参数LIPA标识给SGW，使所述SGW能够根据所述LIPA标识识别本次会话为LIPA会话；在UE签约LIPA属性，且签约接入点名称(APN，Access Point Name)级别和/或UE级别的特定计费特性时，此时可以借用GTPV2消息中自带的特定计费特性参数来标识LIPA，不需要新增参数LIPA标识，因此，在MME发送的创建会话请求中携带标识LIPA的特定计费特性参数给SGW，使所述SGW能够根据所述标识LIPA的特定计费特性参数识别本次会话为LIPA会话。
具体地，通过LGW发送的创建会话响应携带LIPA信息给SGW的场景下，UE仅需要签约LIPA属性，此时在LGW发送的创建会话响应中携带新增参数LIPA标识给SGW，使所述SGW能够根据所述LIPA标识识别本次会话为LIPA会话。
下面结合附图对本发明的具体实施方式进行说明。
通过MME发送的创建会话请求携带LIPA信息给SGW的场景下，本发明实施例提供的LIPA会话的识别方法的基本处理流程如图2所示，包括以下步骤：

这里，所述LIPA信息包括LIPA标识和/或标识LIPA的特定计费特性参数。
未解析出所述创建会话请求中携带有LIPA信息时，SGW确定本次会话为非LIPA会话。
所述SGW针对所述LIPA会话进行计费策略和/或业务策略控制之后，经由LGW向所述MME发送创建会话响应，由所述MME向无线侧网元发送初始上下文建立请求，指示所述无线侧网元与所述LGW建立用户面连接。
这里，所述无线侧网元可以与所述LGW合设；所述无线侧网元可以是E-UTRAN中的eNodeB，也可以是HNB/HeNB；其中，HNB/HeNB是一种小型、低功率、即插即用、使用便捷的基站，部署于家庭及办公室等室内场所，主要作用是为用户提供更高的业务速率，并降低使用高速率服务所需要的费用，同时弥补已有分布式蜂窝无线通信系统覆盖范围的不足。

这里，所述创建会话请求由MME发送，所述创建会话响应由LGW发送。
SGW针对所述LIPA会话进行计费策略和/或业务策略控制之后，经由所述LGW向所述MME发送创建会话响应，由所述MME向无线侧网元发送初始上下文建立请求，指示所述无线侧网元与所述LGW建立用户面连接；或者，
将所述创建会话响应转发给所述MME，由所述MME向无线侧网元发送初始上下文建立请求，指示所述无线侧网元与所述LGW建立用户面连接。
本发明实施例提供的MME侧的LIPA会话的识别方法的基本处理流程如图5所示，包括以下步骤：
步骤S500：MME获取LIPA信息。
这里，所述LIPA信息包括LIPA标识和/或标识LIPA的特定计费特性参数。
