Description

一种本地业务授权方法及相关设备 技术领域
本发明实施例涉及通信技术领域，具体涉及一种本地业务授权方法及相关设备。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴项目(3rdGeneration Partnership Project，3GPP)网络的领先优势，3GPP讨论组在2004年制定了移动通信网络的长期演进计划(Long Term Evolution，LTE)，并在此计划的指导下定义了新的移动通信网络架构—演进的分组系统(Evolved Packet System，EPS)。其中，EPS由用户设备(User Equipment，UE)、接入网和演进的分组核心网(Evolved Packet Core，EPC)组成。在漫游场景中，UE可以从拜访地(后续称为本地)网络接入归属运营商EPC，在本地网络所属的运营商或者第三方服务提供商与归属运营商之间存在漫游协议的情况下，归属运营商可以实现对本地业务的授权。
在实践中发现，如果UE连接的本地网络的运营商(或者第三方服务提供商)与归属运营商之间不存在一对一的漫游协议，那么归属运营商就无法实现对本地网络的本地业务的授权，从而导致UE无法使用本地业务。
发明内容
本发明实施例公开了一种本地业务授权方法及相关设备，能够在漫游场景中，本地网络的服务提供商与归属运营商之间不存在直接漫游协议(如一对一的漫游协议)的情况下，实现归属运营商对本地网络的本地业务的授权。

UE在初始附着归属网络时，归属网络设备可以接收本地网络设备的第一 消息，其中，第一消息包括本地网络的特征信息，本地网络的特征信息包括本地业务信息。归属网络设备获取UE的签约数据，并基于该签约数据和本地业务信息进行本地业务授权，并在本地业务授权通过的情况下，将授权通过的本地业务的标识发送给本地网络设备。
其中，第一消息可以为接入请求消息，如附着请求消息、鉴权与授权请求消息、连接请求消息等。
其中，授权通过的本地业务的标识包括业务类型、应用标识和/或接入点名称(Access Point Name，APN)等。
可选的，该特征信息还可以包括本地网络的服务提供商标识和/或漫游联盟标识。归属网络设备获取UE的签约数据的具体方式可以为：根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据。
其中，服务提供商为部署本地网络的服务提供商、企业、或基础设施提供商、甚至政府部门等。漫游联盟为服务提供商、移动运营商、固网运营商、无线保真(Wireless Fidelity，Wi-Fi)运营商、企业、基础设施提供商、政府部门等多个服务提供商组成的联盟，每个联盟有唯一联盟标识，联盟成员共享此联盟标识，且同一漫游联盟下的服务提供商所部署的网络可以共享。
在漫游场景中，如果本地网络的服务提供商和归属运营商之间不存在一对一的漫游协议，可以是处于同一漫游联盟，UE从本地网络接入归属网络时，归属网络设备可以获知本地网络的本地业务类型，从而可以基于UE的签约数据以及本地网络的本地业务信息对本地网络的本地业务进行授权，以便UE可以使用拜访地的业务，从而可以减少归属网络负载，提高网络资源利用率。
可选的，在归属网络设备为控制面网元的情况下，归属网络设备根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据的具体方式可以为：
控制面网元从HSS获取UE的签约数据，其中，该签约数据包括服务提供商标识和漫游联盟标识任意至少之一所对应的业务信息；
或者，
在归属网络设备为HSS的情况下，归属网络设备根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据的具体方式可以为：
HSS从本地数据库获取UE的签约数据，其中，该签约数据包括服务提供商标识和漫游联盟标识任意至少之一所对应的业务信息。
可选的，归属网络设备基于UE的签约数据和本地业务信息对本地网络进行本地业务授权的具体方式可以为：
归属网络设备判断本地业务信息与签约数据中的业务信息是否匹配，如果匹配，则确定本地业务授权通过；或者，如果不匹配，则确定本地业务授权不通过。
进一步的，业务信息包括业务的标识、服务质量(Quality of Service，QoS)参数阈值条件、业务的计费策略中的至少一种；本地业务信息包括本地业务的标识、本地业务的服务质量参数和本地业务的计费策略中的至少一种；那么归属网络设备判断本地业务信息与业务信息是否匹配的具体方式可以包括以下至少一种：
判断业务的标识中是否存在本地业务的标识，如果存在本地业务的标识，则确定本地业务信息与业务信息匹配；或者，如果不存在本地业务的标识，则确定本地业务信息与业务信息不匹配；
判断本地业务的服务质量参数是否满足服务质量参数阈值条件，如果满足服务质量参数阈值条件，则确定本地业务信息与业务信息匹配；或者，如果不满足服务质量参数阈值条件，则确定本地业务信息与业务信息不匹配；
判断本地业务的计费策略与业务的计费策略是否匹配，如果本地业务的计费策略与业务的计费策略匹配，则确定本地业务信息与业务信息匹配；或者，如果本地业务的计费策略与业务的计费策略不匹配，则确定本地业务信息与业务信息不匹配。
可选的，本地业务信息还可以包括本地业务对应的流描述信息中的至少一种。
在UE的签约数据中扩展包含服务提供商标识和/或漫游联盟标识所支持的 业务信息，归属网络设备从而可以基于UE的签约数据和本地网络的本地业务进行本地业务授权，从而可以实现在本地网络的服务提供商与归属运营商之间不存在一对一漫游协议的情况下，UE使用本地业务。
需要说明的是，如果归属网络设备存储有本地网络的本地业务信息，那么本地网络设备只需发送本地业务的标识，本地业务对应的QoS参数，本地业务对应的计费策略和本地业务对应的流描述信息中的至少一种即可；如果归属网络设备未存储有本地网络的本地业务信息，那么本地网络设备至少需要发送本地业务的标识和本地业务对应的流描述信息。
可选的，该方法还可以包括：
归属网络设备基于授权通过的本地业务生成本地业务选择策略，并将该本地业务选择策略发送给UE。
可以避免UE在发起本地业务时不必要的信息的发送，提高通信资源利用率。
其中，本地业务选择策略可以包括授权通过的本地业务的标识和授权通过的本地业务对应的流描述信息。
可选的，本地业务选择策略还可以包括授权通过的本地业务对应的GW标识等，本发明实施例不做限定。
可选的，如果归属网络设备未存储有本地网络的本地业务信息，且本地网络设备发送的本地业务信息中不包括本地业务对应的流描述信息，那么归属网络设备在对本地网络的本地业务授权通过的情况下，只将授权通过的本地业务的标识发送给本地网络设备，由本地网络设备生成本地业务选择策略并发送给UE。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种本地业务授权方法、相关设备及系统，能够在漫游场景中，本地网络的运营商(或者第三方服务提供商)与归属运营商之间不存在一对一的漫游协议的情况下，实现归属运营商对本地业务的授权。以下分别进行详细说明。
为了更好的理解本发明实施例公开的一种本地业务授权方法及相关设备，下面先对本发明实施例适用的EPS架构进行描述。请参阅图1，图1是本发明 实施例公开的一种EPS架构示意图。在图1所示的架构中，包括UE、本地网络和运营商核心网络EPC。其中，UE可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备，移动台(Mobile station，MS)，终端(terminal)，终端设备(Terminal Equipment)等等。为方便描述，本发明实施例中，上面提到的设备统称为用户设备或UE。
图1所示的系统架构应用于漫游场景，在图1中，本地网络也可以称为拜访地网络，可以是第三方部署的网络，也可以是运营商网络，本发明实施例不做限定。本地网络包括接入节点，如长期演进计划(Long Term Evolution，LTE)接入节点或者LTE-U接入节点，本地网络控制面网元以及本地网络用户面网元。其中，LTE接入节点是指使用授权频谱的基站、接入点(Access Point，AP)等，LTE-U接入节点是指使用非授权频谱的基站、AP等；本地网络控制面网元为移动管理实体(Mobility Management Entity，MME)或控制面节点(Control Point，CP)；本地网络用户面网元为网关(Gate Way，GW)或用户面节点(User Point，UP)。运营商EPC包括控制面网元、用户面网元、HSS和公用数据网关(Public Data Network Gate Way，PGW)。其中，控制面网元为MME、验证、授权和记账(Authentication、Authorization、Accounting，AAA)服务器、演进数据网关(Evolved Packet Data Gateway，ePDG)、通用无线分组业务(General Packet Radio Service，GPRS)服务支持节点(Serving GPRS Support Node，SGSN)或CP；用户面网元包括安全网关(Security Gate Way，SeGW)、服务网关(Serving Gate Way，SGW)或UP，本发明实施例不做限定。
需要说明的是，本发明实施例所提及的本地网络设备可以包括本地网络控制面网元和LTE(LTE-U)接入节点；本发明实施例所提及的归属网络设备是指运营商EPC的控制面网元和HSS，本发明实施例在此不再赘述。
在图1所示的系统架构中，本地网络的服务提供商与UE的归属运营商之间可以存在一对一的漫游协议，也可以不存在一对一的漫游协议，如处于同一 漫游联盟。UE从本地网络接入的归属运营商EPC时，归属运营商EPC(即归属网络设备)需要对UE进行接入授权，即确定是否允许UE从本地网络接入其所属的归属网络，如果归属运营商EPC允许UE从本地网络接入，归属网络设备可以进一步对本地网络的本地业务进行业务授权，并在对本地网络的本地业务授权通过的情况下，归属网络设备或者本地网络设备会基于授权通过的本地业务生成本地业务选择策略，以便UE基于本地业务选择策略发起本地业务。图1所示的系统架构可以在本地网络的服务提供商与归属运营商之间不存在漫游协议的情况下，实现归属运营商对本地网络的本地业务的授权。
基于图1所示的系统架构，本发明实施例公开了一种本地业务授权方法。请参阅图2，图2是本发明实施例公开的一种本地业务授权方法的流程示意图。如图2所示，该本地业务授权方法可以包括以下步骤：
201、UE向本地网络设备发送第二消息。
本发明实施例中，第二消息具体为接入请求消息，用于请求接入UE的归属网络。该接入请求消息可以为附着请求Attach Request消息、鉴权与授权请求Authentication and Authorization Request消息、连接请求消息或者采用NAS消息(如Attach Request消息)承载Diameter消息(如Authentication and Authorization Request消息)等，本发明实施例不做限定。
发明实施例中，UE在接入归属网络时，需要通过本地网络向归属网络发送附着请求。具体的，UE向本地网络的接入节点(可以是采用授权频谱，也可以是采用非授权频谱)发送附着请求，并由接入节点转发附着请求至本地网络的控制面网元。
本发明实施例中，UE还可以将归属网络的标识，如归属公共陆地移动网络(Home public land mobile network，HPLMN)标识作为选择的网络在空口消息中发送给本地网络设备，具体可以是以独立的消息发送出去，也可以是在第二消息中发送出去，本发明实施例不做限定。
可选的，该第二消息中还可以包括UE当前所在的位置信息和接入点信息 中的至少一种，如该UE的地理位置信息(经度，纬度)、3GPP位置信息、归属网络运营商的蜂窝网络广播位置信息(如LTE基站标识)、接入的LTE-U小区标识、接入的LTE-U基站标识、或者本地网络自定义的接入点标识(如“咖啡厅接入点”、“机场接入点”)等，本发明实施例不做限定。
202、本地网络设备接收第二消息，并向归属网络设备发送第一消息，该第一消息包括本地网络的特征信息，第一消息携带第二消息。
本发明实施例中，本地网络设备在接收到UE的第二消息后，会基于归属网络的标识将第二消息和本地网络的特征信息发送给归属网络设备。具体的，本地网络设备将第二消息发送给归属网络的控制面网元，如MME。
本发明实施例中，本地网络的特征信息可以包括本地网络的本地业务信息，其中，本地业务信息可以包括本地业务的标识，本地业务的QoS参数和本地业务的计费策略中的至少一种，可选的，本地业务信息还可以包括本地业务对应的流描述信息。
其中，本地业务的标识可以包括本地业务的类型，如数据业务、语音业务、广告业务、互联网业务等，应用标识，如应用名称，和APN中的至少一个，本发明实施例不做限定。QoS参数可以包括保证比特速率(Guaranteed Bit Rate，GBR)、最大比特速率(Maximum Bit Rate，MBR)、服务质量分类标识(QoS Class Identifier，QCI)、分配与保留优先级(Allocation and Retention Priority，ARP)等。计费策略可以包括预付费、后付费、基于时长计费或者基于流量计费等。流描述信息也可以称为五元组，可以包括源目的互联网协议(Internet Protocol，IP)地址，源目的端口号，协议标识中的至少一个。
需要说明的是，如果归属网络设备存储有本地网络的本地业务信息，那么本地网络设备只需发送本地业务的标识，本地业务的QoS参数，本地业务的计费策略和本地业务对应的流描述信息中的至少一种即可；如果归属网络设备未存储有本地网络的本地业务信息，那么本地网络设备至少需要发送本地业务的标识和本地业务对应的流描述信息。
203、归属网络设备接收第一消息，并基于UE的签约数据和本地网络的特 征信息对UE接入归属网络进行接入授权。
本发明实施例中，本地网络的特征信息还可以包括本地网络使用的安全认证信息，如使用的安全认证方案的标识等，本地网络使用的无线接入技术(Radio Access Technologies，RAT)类型，如LTE-U、LTE等，本地网络接入节点的接入模式，如开放模式，封闭模式，混合模式，本地网络接入节点的安全等级等，本发明实施例不做限定。
本发明实施例中，归属网络设备在接收到第一消息后，会基于UE的签约数据对UE接入归属网络进行接入授权，如确定当前的时间或地点是否允许UE从该接入节点接入归属网络，接入节点的接入模式或者安全等级是否满足允许UE从接入节点接入归属网络的条件，本地网络是否为可信或者非可信网络，以及归属网络时允许UE从可信网络接入还是允许从非可信网络接入，等等，本发明实施例不做限定。
本发明实施例中，如果上述条件均满足允许UE从本地网络接入归属网络，则表示对UE从本地网络接入归属网络授权成功，即UE附着成功。
204、在对UE接入归属网络授权通过的情况下，归属网络设备获取UE的签约数据，并基于该签约数据和本地业务信息对本地网络进行本地业务授权。
本发明实施例中，在对UE从本地网络接入归属网络授权通过的情况下，归属网络设备会获取UE的签约数据，并基于UE的签约数据和本地业务信息对本地网络的本地业务进行授权。
作为一种可行的实施方式，本地网络的特征信息还可以包括本地网络的服务提供商标识(Service Provider Identifier/Identity，SP ID)和/或漫游联盟标识；归属网络设备获取UE的签约数据的具体方式可以为：
归属网络设备根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据。
具体的，在归属网络设备为控制面网元的情况下，归属网络设备根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据的具体方式可以为：
控制面网元从HSS获取UE的签约数据，其中，该签约数据包括服务提供商标识和漫游联盟标识任意至少之一所对应的业务信息；
或者，
在归属网络设备为HSS的情况下，归属网络设备根据服务提供商标识和漫游联盟标识中的至少一种获取UE的签约数据的具体方式可以为：
HSS从本地数据库获取UE的签约数据，其中，该签约数据包括服务提供商标识和漫游联盟标识任意至少之一所对应的业务信息。
本发明实施例中，UE的签约数据扩展包含本地网络的服务提供商标识和/或漫游联盟标识所支持的业务信息。具体的，服务提供商标识和/或漫游联盟标识与业务信息绑定关系。上述业务信息包括业务的标识，如业务类型(数据业务、语音业务、广告业务、互联网业务等)或APN、QoS参数阈值条件(GBR，MBR、QCI、或ARP)、计费策略(如预付费、后付费、基于时长计费、或基于流量计费)中的至少一个。
因此，如果归属网络设备为控制面网元，其获取UE的签约数据具体是从HSS获取，如果归属网络设备为HSS，其获取UE的签约数据具体是从本地数据库中获取，本发明实施例不做限定。
值得注意的是，SP ID为部署本地网络的服务提供商的标识、或部署本地网络的企业标识、或基础设施提供商标识、甚至政府部门标识等。漫游联盟为服务提供商、移动运营商、固网运营商、Wi-Fi运营商、企业、基础设施提供商、政府部门等多个服务提供商组成的联盟，每个联盟有唯一联盟标识(Union ID)，联盟成员共享此联盟标识(Union ID)，且同一漫游联盟下的服务提供商所部署的网络可以共享。
作为另一种可行的实施方式，归属网络设备基于UE的签约数据和本地业务信息对本地网络进行本地业务授权的具体方式可以为：
归属网络设备判断本地业务信息与签约数据中的业务信息是否匹配，如果匹配，则确定本地业务授权通过；或者，如果不匹配，则确定本地业务授权不通过。
那么归属网络设备判断本地业务信息与业务信息是否匹配的具体方式可以包括以下至少一种：
判断业务的标识中是否存在本地业务的标识，如果存在本地业务的标识，则确定本地业务信息与业务信息匹配；或者，如果不存在本地业务的标识，则确定本地业务信息与业务信息不匹配；
判断本地业务的服务质量参数是否满足服务质量参数阈值条件，如果满足服务质量参数阈值条件，则确定本地业务信息与业务信息匹配；或者，如果不满足服务质量参数阈值条件，则确定本地业务信息与业务信息不匹配；
判断本地业务的计费策略与业务的计费策略是否匹配，如果本地业务的计费策略与业务的计费策略匹配，则确定本地业务信息与业务信息匹配；或者，如果本地业务的计费策略与业务的计费策略不匹配，则确定本地业务信息与业务信息不匹配。
具体实现中，在本地网络设备未发送本地网络的本地业务信息的情况下，归属网络设备可以在UE的签约数据中查找是否存在本地网络的服务提供商标识和/或漫游联盟标识对应的业务信息，如果存在，则将业务信息中的业务作为授权通过的本地业务。在本地网络设备发送了本地网络的本地业务信息的情况下，如果UE的签约数据中存在本地网络的服务提供商标识和/或漫游联盟标识对应的业务信息，归属网络设备则可以进一步判断本地业务信息与业务信息是否匹配。
举例来说，归属网设备可以判断本地网络所支持的本地业务类型或者APN与该业务信息中允许的业务类型或者APN是否匹配。进一步的，如果本地业务信息包括本地业务的QoS参数，那么归属网络设备还可以判断本地网络所支持的本地业务的QoS参数是否满足该业务信息中业务的QoS参数阈值条件。例如，当本地网络支持的GBR大于等于UE签约的GBR时，本地业务授权通过。当本地网络支持的MBR小于UE签约的GBR时，本地业务授权不通过。进一步的，如果本地业务信息包括本地业务的计费策略，那么归属网络设备还可以判断本地网络所支持的本地业务的计费策略与该业务信息中业务的计费策略是否匹 配。如果上述条件均匹配，则确定对本地网络的本地业务授权通过。
205、在本地业务授权通过的情况下，归属网络设备将授权通过的本地业务的标识发送给本地网络设备。
具体实现中，归属网络设备在对本地业务授权通过的情况下，可以将授权通过的本地业务的标识发送给本地网络设备，以便本地网络设备在UE发起本地业务的情况下，基于授权通过的本地业务的标识为该UE建立本地业务连接。其中，授权通过的本地业务的标识可以包括但不限于本地业务的类型、应用标识、APN等。
作为又一种可行的实施方式，该方法还可以包括以下操作：
归属网络设备基于授权通过的本地业务生成本地业务选择策略，并将本地业务选择策略发送给UE。
具体实现中，在对本地网络的本地业务授权通过的情况下，归属网络设备会基于授权通过的本地业务生成本地业务选择策略，该本地业务选择策略包括有授权通过的本地业务的标识(如本地业务类型，APN或者应用标识)以及授权通过的本地业务对应的流描述信息。
其中，本地业务选择策略包括的授权通过的本地业务对应的流描述信息可以理解为：本地网络设备将本地业务对应的流描述信息发送给归属网络设备，归属网络设备在对本地业务授权通过后，从中选择出授权通过的本地业务对应的流描述信息；或者，UE的签约数据中存在本地网络的本地业务信息，归属网络设备在对本地业务授权通过后，从中选择出授权通过的本地业务对应的流描述信息。
可选的，本地业务选择策略还可以包括授权通过的本地业务对应的GW标识等，本发明实施例不做限定。
进一步的，归属网络设备在生成本地业务选择策略后，可以将其发送给UE。具体可以是将本地业务选择策略发送给本地网络设备，由本地网络设备转发给UE，也可以是将本地业务选择策略发送给EPS中的归属网络服务设备，如ANDSF服务器，由ANDSF服务器转发给UE，还可以将本地业务选择策略通 过信令发送给UE，本发明实施例不做限定。
可见，在图2所描述的方法中，在漫游场景下，如果本地网络的服务提供商与归属运营商之间不存在一对一的漫游协议，可以是处于同一漫游联盟，UE从本地网络接入归属网络时，归属网络设备可以获知本地网络的本地业务信息，从而可以基于UE的签约数据以及本地业务信息进行本地业务授权，以便UE可以使用拜访地的业务，从而可以减少归属网络负载，提高网络资源利用率。当然，本发明实施例还可以应用于本地网络的服务提供商与归属运营商之间存在一对一的漫游协议的场景中，那么归属网络设备可以通过在UE的签约数据中是否查找到与本地网络的服务提供商的标识或者服务提供商所属的漫游联盟的标识对应的签约信息来进行本地业务授权。
基于图1所示的系统架构，本发明实施例公开了另一种本地业务授权方法。请参阅图3，图3是本发明实施例公开的另一种本地业务授权方法的流程示意图。其中，图3所示的方法实施例中，本地业务选择策略由本地网络设备生成。如图3所示，该本地业务授权方法可以包括以下步骤：
301、UE向本地网络设备发送第二消息。
本发明实施例中，第二消息具体为接入请求消息，用于请求接入UE的归属网络。第二消息还可以包括UE的永久标识，如国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)等。
302、本地网络设备接收第二消息，并向控制面网元发送第一消息，该第一消息携带第二消息，第一消息包括本地网络的特征信息。
本发明实施例中，归属网络设备包括归属网络的控制面网元，如MME，和HSS。本地网络的特征信息可以包括本地网络的服务提供商标识和/或漫游联盟的标识，还可以包括本地网络的本地业务信息。本地业务信息可以包括本地业务的标识，本地业务的QoS参数和本地业务的计费策略中的至少一种。
303、控制面网元接收第一消息，并向HSS发送更新位置请求消息。
本发明实施例中，控制面网元在接收到第一消息后，可以向HSS发送更新 位置请求消息，用于更新为UE提供服务的控制面网元，从而向HSS获取UE的签约数据。其中，该更新位置请求消息还可以将本地网络的服务提供商标识和/或漫游联盟标识发送给HSS。
可选的，本地网络的特征信息还可以包括本地网络使用的安全认证信息，如使用的安全认证方案的标识等，本地网络使用的RAT类型，如LTE-U、LTE等，本地网络接入节点的接入模式，如开放模式，封闭模式，混合模式，本地网络接入节点的安全等级等，本发明实施例不做限定。控制面网元还可以将上述信息发送给HSS，以便HSS基于UE的签约数据对UE从本地网络接入归属网络初次进行接入授权。
304、HSS接收更新位置请求消息，获取UE的签约数据，并基于该签约数据和本地网络的特征信息对UE接入归属网络进行接入授权。
本发明实施例中，HSS接收到更新位置请求消息后，会更新为UE提供服务的控制面网元(如MME)，并根据UE的IMSI查找该UE的签约数据。HSS在查找到该UE的签约数据后，会基于该签约数据对UE从本地网络接入归属网络进行接入授权。
本发明实施例中，HSS基于该UE的签约数据对UE从本地网络接入归属网络进行接入授权的具体方式可以为：
HSS判断该本地网络的特征信息与该签约数据是否匹配；在该特征信息与该签约数据匹配的情况下，允许该UE从本地网络接入归属网络；在该接入信息与该签约数据不匹配的情况下，拒绝该UE从本地网络接入归属网络。
具体的，HSS会基于本地网络使用的RAT类型和该UE的签约数据检测UE是否可以从该接入节点接入，和/或，基于SP ID和/或Union ID检测是否可以从SP ID所标记的服务提供商和/或Union ID所标记的漫游联盟部署的网络接入。
305、在对UE接入归属网络授权通过的情况下，HSS将UE的签约数据发送给控制面网元。
本发明实施例中，在HSS对UE从本地网络接入归属网络授权通过的情况下，HSS可以将UE的签约数据发送给控制面网元。该签约数据包括本地网络 的SP ID和/或Union ID对应的业务信息，该业务信息中包括了允许UE使用的业务的相关信息，如业务标识、QoS参数阈值条件，业务计费策略等。
306、控制面网元接收UE的签约数据，并基于该签约数据和本地业务信息进行本地业务授权。
本发明实施例中，控制面网元在接收到HSS发送的UE的签约数据后，会再次对UE从本地网络接入归属网络进行接入授权，即确定当前的时间或地点是否允许UE从该接入节点接入归属网络，接入节点的接入模式或者安全等级是否满足允许UE从接入节点接入归属网络的条件，本地网络是否为可信或者非可信网络，以及归属网络时允许UE从可信网络接入还是允许从非可信网络接入，等等。
进一步的，在控制面网元对UE从本地网络接入归属网络授权也通过的情况下，如果特征信息中包括本地网络的本地业务信息，控制面网元会基于UE的签约数据和本地网络的本地业务信息、进行本地业务授权，具体方式同上述实施例，本发明实施例在此不再赘述。如果特征信息中不包括本地网络的本地业务信息，控制面网元则将签约信息中的业务作为授权通过的本地业务。
307、在本地业务授权通过的情况下，控制面网元将授权通过的本地业务的标识发送给本地网络设备。
本发明实施例中，控制面网元在对本地网络的本地业务授权通过的情况下，可以将授权通过的本地业务的标识，如业务类型、APN和/或应用标识等发送给本地网络设备。
308、本地网络设备接收授权通过的本地业务的标识，并基于授权通过的本地业务生成本地业务选择策略。
本地网络设备在接收到授权通过的本地业务的标识后，会存储UE、本地网络的服务提供商标识和/或漫游联盟标识与和授权通过的本地业务的标识之间的对应关系。

基于图1所示的系统架构，本发明实施例公开了另一种UE。请参阅图11，图11是本发明实施例公开的另一种UE的结构示意图。其中，图11所描述的UE1100可以应用于上述方法实施例。如图11所示，UE1100可以包括收发器1101和处理器1102，其中：
收发器1101，用于向本地网络设备发送请求消息，其中，该请求消息用于请求UE1100接入UE1100的归属网络，以便本地网络设备在将该请求消息和本地网络的特征信息发送给归属网络设备后，归属网络设备基于请求消息和特征信息对UE1100接入归属网络进行接入授权，并基于UE1100的签约数据和本地网络的特征信息包括的本地业务信息进行本地业务授权。
收发器1101，还用于接收基于授权通过的本地业务生成的本地业务选择策略。
其中，该请求消息可以为接入请求消息。特征信息还可以包括本地网络的 服务提供商标识和/或漫游联盟标识；本地业务信息包括本地业务的标识、本地业务对应的QoS参数、本地业务对应的计费策略和本地业务对应的流描述信息中的至少一种；本地业务选择策略包括授权通过的本地业务的标识和授权通过的本地业务对应的流描述信息。
作为一种可行的实施方式，收发器1101接收基于授权通过的本地业务生成的本地业务选择策略的具体方式可以为：
接收归属网络设备发送的基于授权通过的本地业务生成本地业务选择策略；或者，接收本地网络设备在接收到归属网络设备发送的授权通过的本地业务的标识后，发送的基于授权通过的本地业务生成的本地业务选择策略。
具体实现中，归属网络设备在对本地网络的本地业务授权通过后，可以基于授权通过的本地业务的生成本地业务选择策略，并发送给UE1100；也可以是将授权通过的本地业务的标识发送给本地网络设备，由本地网络设备基于授权通过的本地业务的生成本地业务选择策略，并发送给UE1100，本发明实施例不做限定。

收发器1101，还用于向UE1100请求的本地业务对应的服务网关发送连接建立请求消息，以便GW与UE1100建立安全通道连接，并为UE1100提供UE1100请求的本地业务的服务。
可见，在图10和图11所描述的UE中，在漫游场景下，如果本地网络的 服务提供商与归属运营商之间不存在一对一的漫游协议，可以是处于同一漫游联盟，UE从本地网络接入归属网络时，归属网络设备可以获知本地网络的本地业务类型，从而可以基于UE的签约数据以及本地网络的本地业务信息进行本地业务授权，以便UE可以使用拜访地的业务，从而可以减少归属网络负载，提高网络资源利用率。进一步的，UE可以接收由授权通过的本地业务生成的本地业务选择策略，以便UE能够发起本地业务，从而可以避免不必要的信息的发送，提高通信资源利用率。
基于图1所示的系统架构，本发明实施例公开了一种本地业务授权系统。请参阅图12，图12是本发明实施例公开的一种本地业务授权系统的结构示意图。如图12所示，该系统可以包括UE1201、本地网络设备1202和归属网络设备1203，其中：
UE1201在初始附着归属网络时，可以向本地网络设备1202发送请求消息，用于请求接入归属网络。
本地网络设备1202在接收到UE1201的请求消息后，可以将该请求消息和本地网络的特征信息发送给归属网络设备1203。
归属网络设备1203基于本地网络设备1202发送的信息，对UE从本地网络接入归属网络进行接入授权，在授权通过的情况下，获取UE的签约数据，并基于该签约数据和本地网络的特征信息包括的本地业务信息进行本地业务授权。
其中，本地网络的特征信息还可以包括本地网络的服务提供商标识和/或漫游联盟标识；本地业务信息包括本地业务的标识、本地业务对应的QoS参数、本地业务对应的计费策略和本地业务对应的流描述信息中的至少一种；本地业务选择策略包括授权通过的本地业务的标识和授权通过的本地业务对应的流描述信息。
可选的，本地业务信息还可以包括本地业务对应的流描述信息。
此外，归属网络设备1203在本地业务授权通过的情况下，还会将授权通 过的本地业务的标识，如业务类型、应用名称和/或APN等发送给本地网络设备1202，本地网络设备1202存储UE1201、服务提供商标识和/或漫游联盟标识与授权通过的本地业务的标识的对应关系。
进一步的，归属网络设备1203在本地业务授权通过的情况下，可以基于授权通过的本地业务生成本地业务选择策略，并发送给UE1201。也可以由本地网络设备基于授权通过的本地业务生成本地业务选择策略，并发送给UE1201，本发明实施例不做限定。
UE1201在接收到本地业务选择策略后，可以基于本地业务选择策略发送连接建立请求消息给本地网络设备1202，本地网络设备1202可以基于存储的授权通过的本地业务的标识为UE建立本地业务连接。
可见，在图12所描述的系统中，在漫游场景下，如果本地网络的服务提供商与归属运营商之间不存在一对一的漫游协议，可以是处于同一漫游联盟，UE从本地网络接入归属网络时，归属网络设备可以获知本地网络的本地业务类型，从而可以基于UE的签约数据以及本地网络的本地业务信息进行本地业务授权，以便UE可以使用拜访地的业务，从而可以减少归属网络负载，提高网络资源利用率。进一步的，UE可以接收由授权通过的本地业务生成的本地业务选择策略，以便UE能够发起本地业务，从而可以避免不必要的信息的发送，提高通信资源利用率。
