Description

一种业务分流的方法、系统和设备
本申请要求在2014年1月17日提交中国专利局、申请号为201410023726.7、发明名称为“一种业务分流的方法、系统和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种业务分流的方法、系统和设备。
背景技术
随着新的无线接入技术的出现，未来网络的发展趋势是一个融合多种无线接入技术的异构网络。
目前的典型接入技术有3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)标准组织定义的无线技术，包括UMTS(Universal Mobile Telecommunications System，通用移动通信系统)、LTE(Long Term Evolution，长期演进)、LTE-A(Long Term Evolution-Advanced，长期演进升级)等，以及非3GPP组织定义的无线技术，典型的诸如WI-FI(无线网络)等技术。
在未来的网络中，可能同时部署3GPP网络和WLAN(Wireless Local Area Network，无线局域网)。如图1所示，3GPP网络覆盖范围广，通常作为广域覆盖，可以为用户提供良好的移动性支持；而WLAN覆盖范围小，作为热点覆盖，3GPP网络的用户可以将业务分流到WLAN，从而减少LTE网络的负载。业务分流有很多要求，比如：只有满足了相应的传输速率要求才能将这个业务分流到WLAN；有些业务只能在3GPP网络中发送，不能分流到WLAN。因此如何进行合理的业务分流，保证用户体验，是至关重要的问题。
在现有的规范中，用户设备根据运营商配置的ANDSF(Access Network Discovery and Selection Function，接入网发现和选择功能)将业务进行分流。由于ANDSF的配置是静态配置的，所以无法匹配动态变化的接入网信道状况。
综上所述，目前由于采用静态配置的ANDSF对用户设备的业务进行分流，无法匹配动态变化的接入网信道状况，造成用户设备不能进行合理的业务分流。
发明内容

具体实施方式
本申请实施例用户设备在确定需要进行业务分流后，确定收到的网络侧设备发送的QCI(QoS class Identifier，QoS等级标识；QoS，Quality of Service，业务质量)对应的IP(Internet Protocol，互联网协议)流的属性；根据确定的IP流的属性，在确定IP流能进行分流后，将IP流进行分流处理。由于用户设备能够根据网络侧配置的QCI进行分流处理，而网络侧配置的QCI根据需要可以频繁配置，从而能够适应动态变化的接入网信道状况(比如当3GPP网络负载重时，可以将所有IP流对应的QCI通知给UE，从而配置所有IP流都分流到WLAN，当负载降低时，可以重新向UE通知QCI，从而重新配置让大部分IP流保持在3GPP)，保证业务分流的合理性，提高了业务传输效率。
下面结合说明书附图对本申请实施例作进一步详细描述。
如图2所示，本申请实施例一业务分流的系统包括：用户设备10和网络侧设备20。
用户设备10，用于在确定需要进行业务分流后，确定收到的网络侧设备发送的QCI对应的IP流的属性；根据确定的IP流的属性，在确定IP流能进行分流后，将IP流进行分流处理；
网络侧设备20，用于通过核心网获取QCI，将获取的QCI中的部分或全部QCI通知用户设备。
其中，用户设备将IP流进行分流处理时，将可以分流的IP流分流到WLAN网络中。比如用户设备处于3GPP网络和WLAN网络共存的环境中，如果用户设备确定允许IP流分流，则可以将该IP流分流到WLAN网络中。
在实施中，网络侧设备通知用户设备QCI时，可以将QCI置于QCI列表中，向用户设备发送QCI列表。
网络侧设备可以周期通过核心网获取QCI，也可以根据需要通过核心网获取QCI，比如为用户设备建立一个新的承载时；为用户设备更新一个承载时。
网络侧设备在获取QCI后，还需要选取通知给用户设备的QCI。
具体可以根据当前的网络状况进行选取，下面列举几种选取方式。
选取方式一、当3GPP网络负载较重时，可以只保持QCI为1的IP流(其传输的是VoIP业务)在3GPP网络，允许其他IP流分流到WLAN，同时为对信道要求较高的QCI(比如信道要求级别高于一个阈值的QCI)配置特殊分流条件，保证业务要求。
相应的，选取取值为1的QCI通知给UE。
其中，信道要求较高的QCI为特殊QCI。
选取方式二、
当3GPP网络负载较轻时，可只允许对信道要求较低的QCI(比如信道要求级别低于 一个阈值的QCI)的IP流分流到WLAN，不需要配置特殊的分流条件。
相应的，选取信道要求较低的QCI通知给UE。
需要说明的是，本申请实施例并不局限于上面的两种选取方式，任何能够从多个QCI中选取QCI的方式都适用本申请实施例，比如随机选取N个，按照QCI的值选择前N个等。
在实施中，网络侧设备还可以为用户设备配置分流条件；
相应的，用户设备判断是否满足网络侧设备配置的分流条件；若满足，则确定需要进行业务分流，否则，继续判断。
其中，分流条件包括但不限于下列条件中的一种：
3GPP网络信道的SINR(Signal Interference Noise Ratio，信干噪比)低于第一门限值，且WLAN负载低于第二门限值；
3GPP网络信道的SINR低于第三门限值，且用户设备判断WLAN信号可用；
3GPP网络负载高于第四门限值，且WLAN负载低于第五门限值。
在实施中，具体的分流条件可以由高层配置给网络侧设备；也可以由网络侧设备根据需要进行配置，比如当前3GPP网络将负载状况发送给用户设备时，可以配置需要测量3GPP网络负载的分流条件；否则，只能配置测量3GPP网络SINR的分流条件。
上述门限值也可以根据需要随时进行调整。
其中，IP流的属性包括但不限于下列中的部分或全部：
IP流上的业务是否为运营商发起；
IP流上的业务是否为语音业务；
IP流上的业务是否为数据业务；
IP流是否必须和其他IP流一起分流。
在实施中，IP流的属性具体可以在协议中规定，也可以由网络侧配置给用户设备。
较佳地，本申请实施例还可以根据需要确定一些特殊QCI，针对特殊QCI会对应特殊分流条件。
具体的，网络侧设备从获取的所有QCI中选取需要通知给用户设备的QCI；
然后，网络侧设备从需要通知给用户设备的QCI中查看是否有特殊QCI，如果有特殊QCI，在为用户设备配置分流条件时，需要为用户设备配置特殊QCI对应的特殊分流条件；
相应的，在满足特殊分流条件后，用户设备确定收到的网络侧设备发送的QCI中特殊QCI对应的IP流的属性。
较佳地，如果没有特殊QCI或者除了特殊QCI还有其他QCI，则针对这些QCI，网络侧设备还可以为用户设备配置普通分流条件；
相应的，在满足普通分流条件后，用户设备确定收到的网络侧设备发送的QCI中除特 殊QCI之外的其他QCI对应的IP流的属性。
其中，由于QCI标识的是IP流上业务对服务的要求，网络侧设备可以根据QCI对应的时延和丢包率要求确定哪些是特殊QCI，比如有些QCI要求丢包率很低，则确定该QCI为特殊QCI，对应的IP流就需要特殊分流规则，还比如有些QCI要求时延很小，则确定该QCI为特殊QCI，对应的IP流就需要特殊分流规则。
特殊分流条件与普通分流条件相比具体内容相同，只是其中的参数不同，比如门限值的大小。
网络侧设备在确定特殊QCI后，在通知用户设备时，可以通过标识进行区别，比如1表示特殊，0表示非特殊。
在实施中，本申请实施例的网络侧设备可以是基站(比如宏基站、家庭基站等)，也可以是RN(中继)设备，还可以是其它网络侧设备，例如RAN(Radio Access Network，无线接入网)。

确定模块300具体用于：
在满足特殊分流条件后，确定收到的网络侧设备发送的QCI中特殊QCI对应的IP流的属性；在满足普通分流条件后，确定收到的网络侧设备发送的QCI中除特殊QCI之外的其他QCI对应的IP流的属性。

查询到QCI为1的IP流A是非运营商的业务，判断其可以分流到WLAN，则将IP流A分流到WLAN；
查询到QCI为2的IP流B是非运营商的业务，判断其可以分流到WLAN，则将IP流B分流到WLAN；
查询到QCI为2的IP流D是运营商的业务，判断其不可以分流到WLAN，则将IP流D保持在3GPP网络。
当特殊分流条件β得到满足时进行如下行为：
查询到QCI为3的IP流C是非运营商的业务，判断其可以分流到WLAN，则将IP流C分流到WLAN；
查询到QCI为3的IP流E是运营商的业务，判断其不可以分流到WLAN，则将IP流E保持在3GPP网络。
例3：IP流的属性为IP流上的业务是否为语音业务。
基站根据从核心网获取的信息，得到用户设备的IP流A,B,C,D,E,F的QCI分别是1,2,3,2,3,4。
基站确定可分流QCI为1和2，同时为QCI为3配置了特殊的分流条件β(比如3GPP网络信道SINR低于-2dB同时WLAN负载低于40％)，将可分流QCI列表{1,2,3}和QCI为3的特殊分流条件β发送给用户设备。
用户设备收到基站发送的QCI列表和QCI为3的特殊分流条件β之后，当RAN配置的WLAN分流条件α(比如3GPP网络信道SINR低于0dB同时WLAN负载低于50％)得到满足时进行如下行为：
查询到QCI为1的IP流A是非语音业务，判断其可以分流到WLAN，则将IP流A分流到WLAN；
查询到QCI为2的IP流B是非语音业务，判断其可以分流到WLAN，则将IP流B分流到WLAN；
查询到QCI为2的IP流D是语音业务，判断其不可以分流到WLAN，则将IP流D保持在3GPP网络。
当特殊分流条件β得到满足时进行如下行为：
查询到QCI为3的IP流C是非语音业务，判断其可以分流到WLAN，则将IP流C分流到WLAN；
查询到QCI为3的IP流E是语音业务，判断其不可以分流到WLAN，则将IP流E保持在3GPP网络。
例4：IP流的属性为此IP流是否必须和其他IP流一起分流到WLAN。
基站根据从核心网获取的信息，得到用户设备的IP流A,B,C,D,E,F,G的QCI分别是 1,2,3,2,2,4,2。
基站确定可分流QCI为1和2，同时为QCI为3配置了特殊的分流条件β(比如3GPP网络信道SINR低于-2dB同时WLAN负载低于40％)，将可分流QCI列表{1,2,3}和QCI为3的特殊分流条件β发送给用户设备。
用户设备收到基站发送的QCI列表和QCI为3的特殊分流条件β之后，当RAN配置的WLAN分流条件α(比如3GPP网络信道SINR低于0dB同时WLAN负载低于50％)得到满足时进行如下行为：
查询到QCI为1的IP流A不需要和其他IP流一起切换到WLAN，则将IP流A分流到WLAN；
查询到QCI为2的IP流B必须和IP流C一起分流到WLAN，则先判断IP流C是否可以分流到WLAN；查询到IP流C的QCI为3，特殊分流条件不满足，不能分流到WLAN，则IP流B不能分流到WLAN；
查询到QCI为2的IP流D必须和IP流F一起分流到WLAN，则先判断IP流F是否可以分流到WLAN；查询到IP流F的QCI为4，不在QCI列表中，不能分流到WLAN，则IP流D不能分流到WLAN。
查询到QCI为2的IP流E必须和IP流G一起分流到WLAN，则先判断IP流G是否可以分流到WLAN；查询到IP流G的QCI为2，在QCI列表中，同时没有特殊分流条件，则将IP流E和G一起分流到WLAN。
当特殊分流条件β得到满足时进行如下行为：
查询到QCI为3的IP流C必须和IP流B一起分流到WLAN，则先判断IP流B是否可以分流到WLAN；查询到IP流B的QCI为2，在QCI列表中，此时分流条件α已经满足，则将IP流B和C一起分流到WLAN。
从上述内容可以看出：本申请实施例用户设备在确定需要进行业务分流后，确定收到的网络侧设备发送的QCI对应的IP流的属性；根据确定的IP流的属性，在确定IP流能进行分流后，将IP流进行分流处理。由于用户设备能够根据网络侧配置的QCI进行分流处理，而网络侧配置的QCI根据需要可以频繁配置，从而能够适应动态变化的接入网信道状况(比如当3GPP网络负载重时，可以配置所有IP流都分流到WLAN，当负载降低时，可以重新配置让大部分IP流保持在3GPP)，保证业务分流的合理性，提高了业务传输效率。
