Description

一种信息传输方法、融合网关及系统 技术领域
本申请涉及通信技术领域，尤其涉及一种信息传输方法、融合网关及系统。
背景技术
随着终端技术以及互联网技术的不断发展，移动终端如手机上能够实现的功能越来越多，如用户可通过手机拨打电话、网上冲浪等等，给用户带来极大的便利。目前，对于某些特定区域，如企业的办公区域，一般部署的是私有网络。运营商可通过租用企业站址并部署小型基站(SmallCell)来实现室内无线信号的覆盖。其中，该站址是指基站的地址，如用于安装基站设备的机房。
在实际通信中，私有网络与运营商提供的无线网络是隔离的，企业员工通过终端进行语音或数据通信时，需要将语音或数据回传到各运营商核心网，再经由互联网、公共交换电话网络(英文：Public Switched Telephone Network，简称PSTN)、企业内部私有网络与企业内部实现通信。也就是说，私有网络无法提供和运营商无线网络的融合服务，这就导致企业用户无法通过运营商无线网络直接接入企业的私有网络，也无法利用运营商无线网络的公有资源来实现企业内部增值业务。而且，运营商无线网络要在室内覆盖，往往还存在因站址获取困难而导致室内信号不佳的问题。此外，多个运营商无线网络需要在室内重复建设，也导致建设成本较高。
发明内容

进一步的，当第一用户设备和第二用户设备均为第一网络中的用户，且两者中存在至少一个为普通用户时，可按照第一网络和第二网络预先协商的计费策略确定转发方式。从而可在保持语音、数据、号码不变的情形下，保留公共权限，并可提供多种增值业务及业务接口，以针对不同接入用户类型进行权限管理。
在一些可能的实现中，在融合网关向第一用户设备发送代理服务器地址之后，该融合网关还可向第一用户设备发送该第一网络的网络标识，以使该第一用户设备显示所述网络标识。
其中，所述网络标识可用于标识该第一网络与第二网络的融合部署，如可包括运营商名称、企业名称等标识信息，以标识该融合部署。进一步的，该网络标识可以是预先配置得到的。
在一些可能的实现中，该第一网络的网络标识可以是由融合网关下发的空中消息(英文：Over The Air，简称OTA)中携带的，具体可以是基于网络标识和时区(英文：Network Identity and Time Zone，简称NITZ)机制下发的。从而可实现对网络标识进行自定义定制，增强了用户体验。

进一步的，请参见图3，图3是本发明实施例提供的一种私有网络和公有网络建立连接的逻辑示意图。如图3所示，仍以私有网络为企业网络，公有网络为运营商无线网络为例。企业侧可采用漫游接口与运营商核心网连接，该漫游接口包括S6a、S8、S9接口等等，该S6a、S8、S9接口为第三代合作伙伴计划(英文：The Third Generation Partnership Project，简称3GPP)定义的LTE漫游架构中的接口。在漫游场景下，EPC模块中的MME通过S6a接口连接到运营商侧的归属用户服务器(英文：Home Subscriber Server，简称HSS)，EPC模块中的服务网关(英文：Serving Gate Way，简称S-GW)通过S8接口连接到运营商侧的公用数据网(英文：Public Data Network，简称PDN)网关(英文：PDN Gate Way，简称P-GW)，EPC模块中的策略与计费规则功能(英文：Policy and Charging Rules Function，简称PCRF)通过S9接口连接到运营商侧的PCRF。从而从功能上能够实现将企业私有网络作为运营商网络的一个蜂窝小区，即相当于对运营商网络的补网覆盖。可选的，该私有网络可以同时与多家运营商无线网络连接。
本申请公开了一种信息传输方法、融合网关及系统，能够通过配置融合网关实现私有网络与公有网络的融合服务，改善室内通信信号质量，并降低网络建设成本。
请参见图4，图4是本发明实施例的一种信息传输方法的流程示意图。具体的，本发明的所述方法可具体应用于第一网络，即上述的私有网络中，该第一网络中部署有融合网关，所述第一网络通过所述融合网关与第二网络连接。如图4所示，本发明实施例的所述信息传输方法包括以下步骤：
101、融合网关接收第一用户设备发送的业务请求，所述业务请求包括所述第一用户设备的身份信息以及所述第一用户设备的业务信息；
其中，该第一用户设备可具体指处于该第一网络即私有网络覆盖范围内的用户设备。具体的，该业务请求可以为呼叫请求、数据请求等等。相应的，该业务信息可包括语音信息、数据信息等等。
102、所述融合网关根据所述第一用户设备的身份信息，获取所述第一用户设备在第一网络中的第一用户权限信息；
融合网关可根据该第一用户设备的身份信息确定出其权限，比如，确定出该第一用户设备为私有网络如企业网络中的企业员工，或者为该企业网络中的普通用户(访客)等等。
进一步的，在所述接收第一用户设备发送的业务请求之前，该融合网关还可接收所述第一用户设备发送的用于请求接入所述第一网络的附着请求；所述融合网关响应所述 附着请求，获取为所述融合网关配置的代理服务器地址；所述融合网关向所述第一用户设备发送所述代理服务器地址，以使所述第一用户设备基于所述代理服务器地址接入所述第一网络，并通过所述融合网关与所述第二用户设备进行通信。该通信包括语音通信、数据通信等等。其中，所述代理服务器地址可以具体为P-CSCF地址。
可选的，所述获取为所述融合网关配置的代理服务器地址的具体方式可以为：所述融合网关向所述第二网络转发所述附着请求，并接收所述第二网络针对所述附着请求返回的代理服务器地址；或，所述融合网关通过预设的信令接口获取为所述融合网关配置的代理服务器地址；或，所述融合网关从所述第一用户设备的签约信息中获取为所述融合网关配置的代理服务器地址。
具体地，当用户设备进入私有网络的覆盖区域，如某企业网络范围内时，即可向该企业网络对应的融合网关请求该企业网络的代理服务器地址，具体可向融合网关发送针对该企业网络的附着请求。融合网关在接收到该附着请求后获取该代理服务器地址并发送给该用户设备，以使该用户设备基于该地址进行会话初始协议(英文：Session Initiation Protocol，简称SIP)注册流程，从而实现通过融合网关与其他用户设备进行通信。其中，该第二用户设备可以是指该第一网络中的用户设备，或者还可以是该第二网络中的用户设备。从而实现企业网络内部用户之间，以及企业网络内部用户与外界用户之间的通信。具体的，用户设备可向融合网关发送请求加入企业网络的申请，即上述的附着请求，由企业向运营商网络申请将该用户设备加入企业网络，运营商网络可经由融合网关向该用户设备发送P-CSCF地址；或者，由运营商开放信令接口，如开放LTE中的S6a接口给融合网关，从而获取该P-CSCF地址；或者运营商可将企业员工的签约信息复制一份给融合网关，以仅使该企业网络中的特定用户设备获取到该P-CSCF地址，等等。其中，该S6a接口是在EPC中MME和HSS之间的接口，支持信令的传输，其提供了用户的签约数据管理和鉴权相关的功能。进一步的，该获取P-CSCF地址的方式可设置与用户设备在企业网络中的权限相关联，如为企业网络中的企业员工则直接将存储于融合网关的P-CSCF地址返回给该用户设备，又比如该用户设备为该企业网络中的普通用户时，则融合网关可向运营商网络请求该P-CSCF地址，以使运营商侧决策是否下发该P-CSCF地址。
103、所述融合网关基于所述第一用户权限信息确定将所述业务信息转发给第二用户设备的转发方式。
可选的，该转发方式包括如下任一方式：
通过融合网关直接将该业务信息转发给第二用户设备；或，
通过融合网关向第二网络转发该业务信息，并通过第二网络将该业务信息转发给第二用户设备。
融合网关还可进一步结合该业务信息需要发送的用户设备即第二用户设备在该第一网络中的用户权限信息(即第二用户权限信息)来确定该业务信息的转发方式。所述基于所述用户权限信息确定将所述业务信息转发给第二用户设备的转发方式，可以具体为：所述融合网关获取所述第二用户设备在所述第一网络中的第二用户权限信息；若所述第一用户权限信息指示所述第一用户设备为所述第一网络中的授权用户，且所述第二用户权限信息指示所述第二用户设备也为所述第一网络中的授权用户，则所述融合网关向所述第二用户设备发送所述业务信息；若所述第二用户权限信息指示所述第二用户设 备为所述第二网络中的用户，则所述融合网关向第二网络转发所述业务信息，并通过所述第二网络向所述第二用户设备发送所述业务信息。其中，该授权用户可以是指私有网络中具有一定权限的特定用户，如企业网络中的企业员工。
具体地，对于处于私有网络如企业网络覆盖范围内的用户设备，融合网关可根据获取的其在企业网络中的用户权限信息来确定业务信息的转发路径。例如，当该第一用户设备和第二用户设备均为企业网络内的企业员工时，可直接通过融合网关转发业务信息，即融合网关可直接将接收的第一用户设备的业务信息发送给第二用户设备，或者将接收的第二用户设备的业务信息发送给第一用户设备；当第一用户设备为企业网络内的授权用户或普通用户，第二用户设备为运营商无线网络中的用户时，可采用融合网关+运营商无线网络的方式转发业务信息，即融合网关可将第一用户设备的业务信息转发给运营商无线网络，由运营商无线网络将该业务信息发送给第二用户设备，或者融合网关可接收运营商无线网络转发的第二用户设备的业务信息，由融合网关将该业务信息发送给第一用户设备；当第一用户设备和第二用户设备均为企业网络中的用户，且两者中存在至少一个为普通用户时，可按照企业网络和运营商无线网络预先协商的计费策略确定转发方式，如采用融合网关+运营商无线网络的方式转发业务信息。
具体地，请一并参见图5，图5是本发明实施例提供的一种SIP注册流程的交互示意图。如图5所示，本发明实施例所述的SIP注册流程可包括以下步骤：
201、融合网关对UE进行鉴权；
具体地，当UE处于企业无线网络即私有网络范围内时，可向融合网关发送附着请求(Attach Request)消息，融合网关对该UE进行鉴权。UE具体可以是向EPC模块发送Attach Request，并由EPC模块向IMS模块请求鉴权加密数据，以基于该鉴权加密数据实现融合网关(具体是EPC模块)和UE之间的鉴权加密交互。
202、UE向融合网关发送附着请求；
203、融合网关向UE返回P-CSCF地址；
在完成对UE的鉴权之后，融合网关(EPC模块)可向UE发送ESM(EPS Session Management，EPS会话管理)information request；UE返回ESM information response消息，即上述的附着请求，并可在消息中携带PCO，以通过PCO信元请求该融合网关对应的P-CSCF地址。融合网关(EPC模块)接收到该请求之后，即可获取该P-CSCF地址，并向该UE发送Attach accept消息，该Attach accept消息可携带PCO信元，并可在PCO信元中携带UE请求的P-CSCF IP和UE IP信息等等。
204、UE基于P-CSCF在融合网关进行SIP注册；
在获取得到企业网络对应的P-CSCF地址之后，UE即可向融合网关(IMS模块)发起Sip Register即SIP注册。融合网关(IMS模块)同步UE的鉴权数据与用户数据，进行位置更新。位置更新成功后，融合网关(IMS模块)可向用户回送注册成功消息如200OK，表示注册成功。
205、UE通过融合网关与其他UE进行通信。
进一步的，UE(即第一用户设备)进行SIP注册之后，即可基于该融合网关与其他UE(第二用户设备)如第二网络中的UE进行语音通信。以下以企业网络内的UE发起呼叫(以下称该UE为“主叫UE”)为例进行说明。
主叫UE向融合网关发送呼叫请求，如Invite消息，该Invite消息中包括对端被呼 叫UE(以下称“被叫UE”)的标识等信息。融合网关接收到呼叫请求后，若确定被叫UE为固定电话，则融合网关可为该主叫UE分配在企业网络中的承载信息，并将该呼叫请求转发给被叫UE所在的公有网络即第二网络，具体可转发给第二网络中的PSTN。PSTN接收到该呼叫请求之后，向融合网关返回被叫UE的承载信息。融合网关接收到被叫UE的承载信息后，即可将该主叫UE的承载信息和被叫UE的承载信息转发给主叫UE，以使主叫UE和被叫UE之间建立会话，进行语音通信。当主叫UE发起呼叫结束请求(Bye)消息时，融合网关收到主叫UE的Bye消息后，即可拆除该主叫UE和被叫UE之间的会话。
进一步的，UE进行SIP注册之后，还可基于该融合网关与其他UE进行数据通信。例如，企业网络识别到收发数据的双方UE为企业网络内的企业员工时，可直接通过该融合网关转发数据到企业内部网络或互联网出口，无需通过运营商网络中转，从而提升了访问速度，避免了额外费用的产生。
可选地，在所述融合网关向所述第一用户设备发送所述代理服务器地址之后，所述融合网关还可向所述第一用户设备发送所述第一网络的网络标识，以使所述第一用户设备显示所述网络标识。其中，所述网络标识用于标识该第一网络与第二网络的融合部署，具体可包括运营商名称、企业名称等等，如该网络标识可以为中国联通(清华大学)、中国移动(深圳地铁)等等。进一步的，该网络标识可以是预先配置设置得到的。比如，该网络标识可以是企业网络的管理者自定义配置的，或者由企业网络的用户向运营商申请，运营商根据企业需求配置的，等等，本发明实施例不做限定。
具体地，UE接收并存储融合网关发送的第一网络的网络标识，并可通过判断该第一网络的公用陆地移动通信网(英文：Public Land Mobile Network，简称PLMN)是否与所述第一用户设备对应的国际移动用户识别码(英文：International Mobile Subscriber Identity，简称IMSI)中的PLMN或服务商显示信息(英文：Service Provider Display Information，简称SPDI)相匹配；若否，则显示所述当前PLMN对应的网络标识。
具体地，在刚开机时，或者在第一用户设备的用户识别模块中读取的运营商名(英文：Service Provider Name，简称SPN)为空时，该第一用户设备可只显示该第一网络的PLMN的网络标识。若该第一网络的PLMNPLMN与该用户识别模块中的IMSI中的PLMN或SPDI相匹配，则可在第一用户设备上显示SPN，并根据预设的配置文件如EFSPN(Elementary File，基本文件)中指定的规则确定是否显示该第一网络的PLMN的网络标识(即第一网络的网络标识)。具体可判断EFSPN的第一字节(Display Condition字段)的最低位，若该最低位为1，显示该PLMN的网络标识，若该最低位为0，则不显示该PLMN的网络标识。若当前PLMN与用户识别模块中的IMSI中的PLMN或SPDI不匹配，则表示该第一用户设备处于漫游状态，则可显示该PLMN的网络标识，并可具体判断EFSPN的第一字节(Display Condition字段)的次低位，若该次低位为0，显示SPN，若为1，则不显示SPN。
其中，该用户识别模块可以是指可具体为手机卡，比如客户识别模块(英文：Subscriber Identity Module，简称SIM)，也称用户身份识别卡、智能卡，或者为全球用户识别卡(英文：Universal Subscriber Identity Module，简称USIM)，或者为通用集成电路卡(英文：Universal Integrated Circuit Card，简称UICC)，或者为用户识别模块(英文：User Identify Module，简称UIM)等等，本发明实施例不做限定。
其中，该第一网络的PLMN的网络标识可以是由融合网关下发的OTA消息中携带的。具体的，该PLMN的网络标识可以是基于NITZ机制并通过融合网关下发，在OTA消息中通过MM_INFORMATION携带的。其中，该OTA消息中的MM_INFORMATION包括运营商名称、时区时间等信息，并具体可以是在RRC连接建立的过程中融合网关将该消息发送给该第一用户设备的。从而能够实现私有网络如企业网络的网络标识的自定义定制，如可定制网络标识为中国联通(清华大学)、中国移动(深圳地铁)来区分运营商服务的公共范围和特定范围，提示用户位于特定区域范围内，以针对不同用户类型进行权限管理。
在本申请提供的技术方案中，融合网关可在确定UE需要接入私有网络时，告知UE该私有网络的P-CSCF地址，以使UE基于该P-CSCF地址进行SIP注册，从而在接收到用户设备发送的业务请求时，通过获取该用户设备在第一网络中的用户权限信息，并基于该用户权限信息确定将该业务请求对应的业务信息通过融合网关直接转发给其他用户设备，或者通过融合网关向第二网络转发业务信息，并通过该第二网络将所述业务信息转发给所述第二用户设备，从而实现企业私有网络中的用户设备与其他用户设备之间的语音通信及数据通信，可无需通过运营商网络中转，使得能够提供私有网络与公有网络的融合服务，提升了通信效率，改善了室内通信信号质量，并降低了通信成本。本申请的私有网络和公有网络的融合方案可在保持语音、数据、号码不变的情形下，保留公共权限，实现对私有网络的标识进行自定义定制，并可提供多种增值业务(如三方通话，呼叫保持，呼叫转移等)及业务接口，以针对不同接入用户类型进行权限管理。该融合方案支持多运营商频段，降低了总建设成本。提高了室内部署的积极主动性，并提升室内覆盖的通信信号的质量。
