当MME的负载较重时，MME向基站发送过载启动(Overload Start)消息，过载启动消息用于指示基站仅允许终端设备为某些类型的业务建立RRC连接。但对于某一类型的业务来讲，采用UP方案进行业务数据的传输时，对MME带来的负载较轻；采用CP方案进行业务数据的传输时，对MME带来的负载较重。MME指示基站将某一类型的业务全部拒绝接入时，并未考虑终端设备的数据传输属性的不同所导致的负载影响，MME资源的利用率较低。
发明内容
为了解决MME在负载较重时指示基站将某一类型的业务全部拒绝接入而导致的MME利用率低的问题，本发明实施例提供了一种无线接入控制方法、装置及系统。所述技术方案如下：

在该无线接入控制方法中，通过MME在负载较重时，指示禁止接入和/或允许接入的是某一类业务中满足数据传输属性的一部分业务，而不一定是该类业务中的所有业务，解决了MME在负载较重时指示接入网设备禁止接入某一类型的所有业务而导致的MME资源的利用率低的问题；达到了接入网设备可以根据MME的指示，仅对同时满足业务类型和数据传输属性的业务进行禁止接入和/或允许接入，在保证MME的负载不明显增加的前提下，尽可能为多种业务类型的业务提供服务能力，从而提高网络资源的利用率的效果。

比如，过载启动消息具有默认的动作类型为禁止接入，过载启动消息内携带的信息是(mo-Data，CP)，其中，mo-Data是业务类型字段，CP是传输方案类型字段，该过载启动消息用于指示被禁止的是使用CP方案传输的mo-Data业务；

可选的，当MME需要向接入网设备指示的动作类型和/或业务类型和/或传输方案类型包括多个时，MME可以在向接入网设备发送的一个过载启动消息中集中进行指示，或者，在向接入网设备发送的多个过载启动消息中分别指示，本实施例对此不作限定。
比如，当MME需要向接入网设备指示被禁止的是使用CP方案传输的mo-Data业务，以及被禁止的是使用CP方案传输的mo-ExceptionData业务时，MME可以在同一个过载启动消息中进行集中指示，例如((mo-Data，CP)，(mo-ExceptionData，CP))，该过载启动消息具有默认的动作类型为禁止接入；或者，MME可以在多个过载启动消息中进行分别指示，一个过载启动消息是(禁止，mo-Data，CP)，另一个过载启动消息是(禁止，mo-ExceptionData，CP)。
步骤602，接入网设备接收MME发送的过载启动消息。
当过载启动消息中包括业务类型字段和传输方案类型字段，过载启动消息具有默认的动作类型时，接入网设备确定过载启动消息的默认动作类型，并通过对业务类型字段解析的到业务类型，对传输方案类型字段解析得到传输方案类型。
当过载启动消息中包括动作类型字段、业务类型字段和传输方案类型字段时，接入网设备通过对动作类型字段解析得到动作类型，通过对业务类型字段解析得到业务类型，通过对传输方案类型字段解析得到传输方案类型。
步骤603，接入网设备根据过载启动消息生成接入控制信息，接入控制信息用于向终端设备指示被禁止的业务类型和被禁止的数据传输属性，和/或，被允许的业务类型和被允许的传输方案类型。
接入控制信息用于指示的动作类型与接入网设备确定的过载启动消息的动作类型相同。
接入控制信息用于指示的业务类型与接入网设备从过载启动消息的业务类型字段中解析得到的业务类型相同；接入控制信息用于指示的传输方案类型 与接入网设备从过载启动消息的数据传输属性字段中解析得到的传输方案类型相同。
接入网设备通过生成的接入控制信息向终端设备指示被禁止的业务类型和被禁止的传输方案类型，和/或，被允许的业务类型和被允许的传输方案类型，有两种不同的实现方式，在不同的实现方式中，接入控制信息中包括的内容不同：
在第一种可能的实现方式中，接入控制信息包括：业务类型字段和数据传输属性字段，接入控制信息具有默认的动作类型，动作类型是禁止接入和允许接入中的至少一种。
在第二种可能的实现方式中，接入控制信息包括：动作类型字段、业务类型字段和数据传输属性字段，动作类型字段用于指示该接入控制信息具有的动作类型，动作类型字段包括：禁止接入和允许接入中的至少一种。
本实施例对该步骤使用的实现方式不作限定。
接入控制信息的形式可以与过载启动消息的形式相同，本实施例对此不再赘述。
步骤604，接入网设备向终端设备发送接入控制信息。
可选的，接入网设备采用专用信令向终端设备发送该接入控制信息，或者，在该接入网设备的覆盖范围内以广播消息形式发送该接入控制信息。
当接入网设备需要向终端设备指示的动作类型和/或业务类型和/或传输方案类型包括多个时，接入网设备在向终端设备发送的同一个接入控制信息中进行集中指示，或者，在向终端设备发送的多个接入控制信息分别指示，本实施例对此不作限定。
步骤605，终端设备接收接入网设备发送的接入控制信息。
当接入控制信息中包括业务类型字段和数据传输属性字段，接入控制信息具有默认的动作类型时，终端设备确定接入控制信息的默认动作类型，并通过对业务类型字段解析得到业务类型，对数据传输属性字段解析得到传输方案类型。
当接入控制信息中包括动作类型字段、业务类型字段和数据传输属性字段时，终端设备通过对动作类型字段解析得到动作类型，通过对业务类型字段解析得到业务类型，通过对数据传输属性字段解析得到传输方案类型。
动作类型是禁止接入和允许接入中的至少一种，当动作类型是允许接入 时，则该方法包括下列步骤606：
步骤606，在当前业务的业务类型符合被允许的业务类型且当前业务对应的传输方案类型符合被允许的传输方案类型时，终端设备向接入网设备发送RRC连接请求。
其中，当前业务对应的传输方案类型是指，终端设备传输当前业务时使用的传输方案类型。
终端设备对接入控制信息中的业务类型字段解析得到的业务类型即为被允许的业务，对数据传输属性字段解析得到的传输方案类型即为被允许的传输方案类型。
比如，终端设备接收到的接入控制信息是(mo-Data，UP)，该接入控制信息具有默认的动作类型是允许接入，则终端设备通过对接入控制信息解析确定该接入控制信息是用于指示被允许的业务是使用UP方案传输的mo-Data业务，当终端设备当前待传输的业务是使用UP方案传输的mo-Data业务时，该终端设备向接入网设备发送RRC连接请求；当终端设备当前传输的业务是使用CP方案传输的mo-Data业务时，不向接入网设备发送RRC连接请求。
当动作类型是禁止接入时，有两种不同的实现方式：
在第一种实现方式中，终端设备接收到的接入控制信息包括接入控制因子和接入控制时间，终端设备根据接入控制因子和接入控制时间确定是否向接入网设备发送RRC连接请求；
其中，接入控制因子是用于与终端设备生成的随机数进行比较的阈值，接入控制时间是当终端设备生成的随机数大于或等于控制因子时用于设置定时器的时间。
在第二种实现方式中，终端设备接收到的接入控制信息中包括禁止接入等级，终端设备根据禁止接入等级确定是否向接入网设备发送RRC连接请求。
在本实施例中，以第一种实现方式为例进行说明，则该方法还包括下列步骤607-步骤610：
步骤607，在当前业务的业务类型符合被禁止的业务类型且当前业务对应的传输方案类型符合被禁止的传输方案类型时，生成随机数。
终端设备按照预定算法，生成属于(0,1)的一个随机数。
步骤608，终端设备判断随机数是否小于接入控制因子。
可选的，接入控制因子等于0.5。
步骤609，当随机数小于接入控制因子时，终端设备确定向接入网设备发送RRC连接请求。
步骤610，当随机数大于或等于接入控制因子时，根据接入控制时间设置定时器，在定时器超时时，重新执行生成随机数的步骤。
可选的，接入控制时间是10秒。
可选的，定时器的定时时长＝(0.7+0.6*rand)*接入控制时间，其中，rand是终端设备生成的一个在0至1之间均匀分布的随机数，当定时器超时时，重新执行上述步骤607。需要说明的是，步骤609-步骤610也可以实现成为当随机数大于或等于接入控制因子时，终端设备确定向接入网设备发送RRC连接请求，当随机数小于接入控制因子时，根据接入控制时间设置定时器，在定时器超时时，重新执行生成随机数的步骤，本实施例对此不作限定。
在一个示例性的例子中，终端设备接收到的接入控制信息是(禁止，mo-Data，CP)，终端设备通过对接入控制信息解析确定该接入控制信息是用于指示被禁止的业务是使用CP方案传输的mo-Data业务，当终端设备当前传输的业务的业务类型是mo-Data业务，且终端设备在传输该业务时的传输方案类型是CP方案时，终端设备根据接入控制信息确定接入控制因子为0.5，接入控制时间为10秒，终端设备生成一个随机数假设为0.7，由于0.7＞0.5，则再生成一个随机数假设为0.4，则终端设备设置定时器的定时时长＝(0.7+0.6*0.4)*10＝9.4秒，则定时器超时时，即经过9.4秒后，终端设备重新生成随机数假设为0.3，由于0.3＜0.5，则终端设备确定向接入网设备发送RRC连接请求。
需要说明的是，一个接入控制信息中指示的动作类型可以包括多个，且可以同时包括允许接入和禁止接入，但被允许接入的业务类型和传输方案类型与被禁止接入的业务类型和传输方案类型不存在交集。相关的实现方式与上述方法相同，本实施例对此不再赘述。
在基于上述所示实施例的可选实施例中，以终端设备接收到的接入控制信息的动作类型是禁止接入，且使用上述第二种实现方式确定是否向接入网设备发送RRC连接请求为例进行说明，则终端设备接收到的接入控制信息中还包括禁止接入等级，上述步骤607-步骤610可被替代实现为如下任一步骤，如图7所示：
步骤701，在当前业务的业务类型符合被禁止的业务类型且当前业务对应 的传输方案类型符合被禁止的传输方案类型时，检测终端设备的接入等级是否等于禁止接入等级；若终端设备的接入等级不等于禁止接入等级，则终端设备确定向接入网设备发送RRC连接请求。
不同的终端设备的接入等级不同，终端设备的接入等级是预设的。
在一个示例性的例子中，终端设备接收到的接入控制信息是(禁止，mo-Data，CP)，终端设备通过对接入控制信息解析确定该接入控制信息是用于指示被禁止的业务是使用CP方案传输的mo-Data业务，当终端设备当前传输的业务的业务类型是mo-Data业务，且终端设备在传输该业务时的传输方案类型是CP方案时，终端设备确定接入控制信息中包括的禁止接入等级是2，当终端设备的接入等级是2时，终端设备不向接入网设备发送RRC连接请求；当终端设备的接入等级是3时，终端设备向接入网设备发送RRC连接请求。
或者，作为步骤701的另一种可替代的实现方案，如下步骤702所示：
步骤702，在当前业务的业务类型符合被禁止的业务类型且当前业务对应的传输方案类型符合被禁止的传输方案类型时，检测终端设备的接入等级是否大于禁止接入等级；若终端设备的接入等级小于禁止接入等级，则确定向接入网设备发送RRC连接请求。
在上述示例性实施例中，当终端设备当前传输的业务的业务类型是mo-Data业务，且终端设备在传输该业务时的传输方案类型是CP方案，终端设备确定的接入控制信息中包括的禁止接入等级是2，若终端设备的接入等级是1，则终端设备向接入网设备发送RRC连接请求；若终端设备的接入等级是3，则终端设备不向接入网设备发送RRC连接请求。
或者，作为步骤701的另一种可替代的实现方案，如下步骤703所示：
步骤703，在当前业务的业务类型符合被禁止的业务类型且当前业务对应的传输方案类型符合被禁止的传输方案类型时，检测终端设备的接入等级是否小于禁止接入等级；若终端设备的接入等级大于禁止接入等级，则确定向接入网设备发送RRC连接请求。
在上述示例性实施例中，当终端设备当前传输的业务的业务类型是mo-Data业务，且终端设备在传输该业务时的传输方案类型是CP方案时，终端设备确定的接入控制信息中包括的禁止接入等级是2，若终端设备的接入等级是3，则终端设备向接入网设备发送RRC连接请求；若终端设备的接入等级是1，则终端设备不向接入网设备发送RRC连接请求。

步骤1103，在当前业务的业务类型符合被禁止的业务类型且当前业务对应的数据传输属性符合被禁止的数据传输属性时，检测终端设备的接入等级是否小于禁止接入等级；若终端设备的接入等级大于禁止接入等级，则确定向接入网设备发送RRC连接请求。
在该实施例中，上述步骤1101-步骤1103的实现方式可以结合图7所示实施例中的步骤701-步骤703，本实施例对此不再赘述，终端设备使用上述步骤1101-步骤1103中的任一步骤，本实施例对具体使用的步骤不作限定。
综上所述，本公开实施例提供的无线接入控制方法，通过MME在负载较重时，指示禁止接入和/或允许接入的是某一类业务中满足数据传输属性的一部分业务，而不一定是该类业务中的所有业务，解决了MME在负载较重时指示接入网设备禁止接入某一类型的所有业务而导致的MME资源的利用率低的问题；达到了接入网设备可以根据MME的指示，仅对同时满足业务类型和数据 传输属性的业务进行禁止接入和/或允许接入，达到了在保证MME的负载不明显增加的前提下，尽可能为多种业务类型的业务提供服务能力，从而提高网络资源的利用率的效果。
本实施例提供的无线接入控制方法，通过MME向接入网设备指示被禁止和/或被允许的业务类型和数据传输属性，数据传输属性包括传输方案类型和RAT类型，达到了MME可以指示接入网设备仅禁止和/或允许采用某一RAT类型接入的终端设备使用某一传输方案类型传输的某一种业务，达到了当MME负载较重时，仍然可以允许某一类终端设备传输的负载较轻的业务，提高了对网络资源的利用率的效果，提高了网络服务的质量的效果。
请参考图12A，其示出了本发明另一个示例性实施例提供的无线接入控制方法的流程图。本实施例以该方法应用于图1所示的无线接入控制系统中进行说明，该方法包括：
步骤1201，在负载大于预设条件时，MME向接入网设备发送过载启动消息，过载启动消息用于向接入网设备指示被禁止的业务类型和被禁止的数据传输属性，和/或，被允许的业务类型和被允许的数据传输属性。
步骤1202，接入网设备接收MME发送的过载启动消息。
接入网设备根据过载启动消息确定被禁止的业务类型和被禁止的数据传输属性，和/或，被允许的业务类型和被允许的数据传输属性，与上述实施例中相同，本实施例对此不再赘述。
步骤1203，终端设备向接入网设备发送RRC连接请求消息，RRC连接请求具有对应的业务类型和数据传输属性。
其中，RRC连接请求是由终端设备传输的业务进行触发的，RRC连接请求对应的业务类型和数据传输属性是指触发该RRC连接请求的业务的类型以及终端设备在传输该业务时的数据传输属性。
比如，终端设备采用CP方案传输mo-Data业务时触发该RRC连接请求，则该RRC连接请求对应的业务类型是mo-Data业务，对应的数据传输属性是CP方案。
可选的，RRC连接请求消息还包括：业务类型字段和数据传输属性字段。
其中，业务类型字段用于指示业务类型，数据传输属性字段用于指示数据传输属性，业务类型字段和数据传输属性字段的内容与上述示例性实施例中相 同，本实施例对此不再赘述。
步骤1204，接入网设备接收终端设备发送的RRC连接请求消息。
接入网设备通过对RRC连接请求消息解析确定RRC连接请求对应的业务类型和数据传输属性。
步骤1205，接入网设备根据与RRC连接请求对应的业务类型和数据传输属性是否属于被禁止的业务类型和被禁止的数据传输属性，和/或，被允许的业务类型和被允许的数据传输属性，向终端设备发送RRC连接建立消息或RRC连接拒绝消息。
在与RRC连接请求对应的业务类型和数据传输属性是被允许的业务类型和数据传输属性时，向终端设备发送RRC连接建立消息，并与终端设备建立RRC连接。
在与RRC连接请求对应的业务类型和数据传输属性是被禁止的业务类型和数据传输属性时，向终端设备发送RRC连接拒绝消息。
可选的，在与RRC连接请求对应的业务类型和数据传输属性是被禁止的业务类型和数据传输属性时，还包括两种不同的实现方式：
在第一种可能的实现方式中，在与RRC连接请求对应的业务类型和数据传输属性是被禁止的业务类型和数据传输属性时，接入网设备生成随机数，判断随机数是否小于接入控制因子，当随机数小于接入控制因子时，接入网设备向终端设备发送RRC连接消息；当随机数不小于接入控制因子时，接入网设备向终端设备发送RRC连接拒绝消息，接入控制因子和含义及具体实现方式可以结合上述实施例，本实施例对此不再赘述。
在第二种可能的实现方式中，RRC连接请求消息中还包括终端设备的接入等级。
在与RRC连接请求对应的业务类型和数据传输属性是被禁止的业务类型和数据传输属性时，接入网设备判断终端设备的接入等级是否等于禁止接入等级，若终端设备的接入等级不等于禁止接入等级，则接入网设备而向终端设备发送RRC连接建立消息；若终端设备的接入等级等于禁止接入等级，则接入网设备向终端设备发送RRC连接拒绝消息，该方法还可以实现成为检测终端设备的接入等级是否大于或/是否小于禁止接入等级，具体实现方式与上述实施例中相似，本实施例对此不再赘述。
步骤1206，终端设备接收接入网设备发送的RRC连接建立消息或RRC连 接拒绝消息。
在图12A所示实施例中，RRC连接请求对应的业务类型和数据传输属性是与RRC连接消息请求一起发送的，在其他可选实施例中，终端设备还可以只将RRC连接请求对应的业务类型与RRC连接消息请求一起发送，而在发送RRC连接消息请求之前发送RRC连接请求对应的数据传输属性，则上述步骤1201-步骤1204可被替代实现为如下步骤，如图12B所示：
步骤1210，在负载大于预设条件时，MME向接入网设备发送过载启动消息，过载启动消息用于向接入网设备指示被禁止的业务类型和被禁止的数据传输属性，和/或，被允许的业务类型和被允许的数据传输属性。
步骤1211，接入网设备接收MME发送的过载启动消息。
步骤1212，终端设备向接入网设备发送与RRC连接请求对应的数据传输属性。
步骤1213，接入网设备接收终端设备发送的与RRC连接请求对应的数据传输属性。
可选地，接入网设备预先将随机接入前导码(Random Access Preamble)和数据传输属性的对应关系发送给终端设备，终端设备根据RRC连接请求对应的数据传输属性选择该数据传输属性对应的前导码向接入网设备发送随机接入请求，接入网设备根据终端设备发送的随机接入请求所使用的前导码来确定RRC连接请求对应的数据传输属性。
例如，当数据传输属性包括传输方案类型CP方案或者UP方案时，接入网设备预先告知终端设备前导码A和CP方案相对应，前导码B和UP方案相对应，而触发终端设备发起RRC连接请求的业务使用的是CP方案，则终端设备选择前导码A向接入网设备发起随机接入请求，接入网设备接收随机接入请求，根据该随机接入请求所使用的前导码是A确定终端设备的RRC连接请求对应的数据传输属性是CP方案。
再例如，当数据传输属性包括无线接入技术WB-E-UTRAN或者NB-IoT时，接入网设备预先告知终端设备前导码C和WB-E-UTRAN相对应，前导码D和NB-IoT相对应，而触发终端设备发起RRC连接请求的业务使用的是NB-IoT，则终端设备选择前导码D向接入网设备发起随机接入请求，接入网设备接收随机接入请求，根据该随机接入请求所使用的前导码是D确定终端设 备的RRC连接请求对应的数据传输属性是NB-IoT。
步骤1214，终端设备向接入网设备发送RRC连接请求消息，RRC连接请求具有对应的业务类型和数据传输属性。
该RRC连接请求消息还包括：业务类型字段。
其中，业务类型字段用于指示业务类型，业务类型字段的内容与上述示例性实施例中相同，本实施例对此不再赘述。
步骤1215，接入网设备接收终端设备发送的RRC连接请求消息。
综上所述，本公开实施例提供的无线接入控制方法，通过MME在负载较重时，指示禁止接入和/或允许接入的是某一类业务中满足数据传输属性的一部分业务，而不一定是该类业务中的所有业务，解决了MME在负载较重时指示接入网设备禁止接入某一类型的所有业务而导致的MME资源的利用率低的问题；达到了接入网设备可以根据MME的指示，仅对同时满足业务类型和数据传输属性的业务进行禁止接入和/或允许接入，达到了在保证MME的负载不明显增加的前提下，尽可能为多种业务类型的业务提供服务能力，从而提高网络资源的利用率的效果。
