Abstract

本申请实施例提供一种发送业务请求的方法、装置及系统，涉及通信领域，实现对连接态终端设备新业务的接入控制，进而控制网络侧设备的负载。具体包括：终端设备从第一网络设备接收第一接入控制信息；在连接态时，若第一接入控制信息指示第一业务被禁止接入，终端设备停止向第一网络设备发送第一业务的业务请求。本申请用于发送业务请求。

Description

一种发送业务请求的方法、装置及系统 技术领域
本申请涉及通信领域，尤其涉及一种发送业务请求的方法、装置及系统。
背景技术
在移动通信中，空闲态的用户设备(User Equipment，UE)在业务发起时，先向网络侧的基站发送连接建立请求，与基站建立无线链路连接进入连接态，UE在连接态与基站进行数据传输。现有技术中，基站会控制一些通信业务的接入，例如通过广播消息控制一些通信业务类型是允许接入的，一些通信业务类型是不允许接入的，或一些通信业务类型是根据UE生成的随机数确定是否允许接入。这样，当UE请求连接建立时，UE根据基站广播的内容检查触发其请求建立连接的通信业务类型是否是基站所允许的。如果UE发起的业务类型是基站不允许的，则UE不发送连接建立请求，否则，发送连接建立请求。
但是，除了空闲态UE向基站发起通信业务之外，连接态的UE也会发起一些通信业务，例如，下载文件时向外打电话，浏览网页时有电话打进来。这时，由于UE已经在连接态，UE不需要再检查新发起的业务是否是eNB允许或禁止的。若大量UE当前与基站正在进行紧急通信，已经达到了基站负载的可接受程度，若此时连接态的UE发起新的业务，则会冲击到网络，导致基站过载，使得正在进行的紧急通信被打断。

具体实施方式
基于此，本申请提出一种发送新的业务传输请求的方法，用于控制终端设备在连接态发起业务，其基本原理是：终端设备根据第一接入控制信息的指示，在连接态发起业务时，若第一接入控制信息指示该业务被禁止接入，则停止发起该业务。因此，只要根据需求配置第一接入控制信息，即可对连接态终端发起业务进行控制，进而控制网络侧的负载，保证网络服务质量。

再一方面，本申请实施例提供一种发送业务请求的方法，应用于终端设备与第一网络设备的交互过程中。本申请实施例提供的发送业务请求的方法，可以是终端设备和/或第一网络设备执行，也可以是终端设备和/或第一网络设备中的功能单元或者芯片执行，本申请实施例对此不进行具体限定。在下面实施例的描述的终端设备和/或第一网络设备执行某动作，可以替换为终端设备和/或第一网络设备的功能单元或者芯片执行该动作，不再一一赘述。终端设备和/或第一网络设备内执行本申请提供的发送业务请求的方法的功能单元或者芯片可以称之为发送业务请求的装置。
如图5所示，本申请实施例提供的发送业务请求的方法可以包括：
S501、第一网络设备确定第一接入控制信息。
其中，第一接入控制消息用于控制终端设备连接态的业务请求。
可选的，第一网络设备可以为基站的部分或全部；当第一网络设备为基站的部分时，第一网络设备可以为基站中的功能单元或者至少一个芯片。基站为无线网络中的接入网设备，负责将终端设备接入核心网，实现终端设备与核心网的通信。示例性的，基站可以为4G网络中的eNB，或者，基站可以为5G网络中的gNB，本申请对于基站的类型不进行限定，在不同类型的网络中，基站可以有不同的类型。
其中，第一接入控制信息用于控制连接态终端设备的业务接入，第一接入控制信息的内容指示了处于连接态的终端设备的哪些业务被网络侧所禁止，哪些业务被网络侧允许。需要说明的是，被网络侧禁止或允许，可以是第一网络设备禁止或允许，也可以是其他网络设备禁止或允许，本申请实施例对此不进行具体限定。所述禁止指的是禁止连接态的终端设备发起某些业务，即禁止终端设备的某些业务接入到网络。例如，第一接入控制信息指示连接态的终端设备的业务A禁止接入网络，则当终端设备在发起业务A的业务请求时，根据第一接入控制信息的指示，认为业务A的业务请求是禁止的，即不向网络设备发送业务A的业务请求。同样的，所述允许指的是允许连接态的终端设备发起某些业务，即允许终端设备的某些业务接入到网络。例如，第一接入控制信息指示连接态的终端设备的业务B允许接入网络，则当终端设备在发送业务B的业务请求时，根据第一接入控制信息的指示，认为业务B的业务请求是允许的，即向网络设备发送业务B的业务请求。本文中，不禁止与允许意义相同，禁止与不允许意义相同。本文中，若无特别说明，终端设备处于连接态。
可选的，第一接入控制信息可以包括下述信息中至少一项：使能指示信息、允许发起的业务类型、禁止发起的业务类型、允许发起业务的终端设备类型、禁止发起业务的终端设备类型、使能接入控制策略的指示信息。
其中，使能指示信息用于指示终端设备是否需要根据第一接入控制信息确定第一业务是否被禁止接入，即使能或去使能连控制连接态终端设备发送业务请求的机制。例如，当该使能指示信息指示使能该机制时，终端设备根据网络设备发送的接入控制信息判断其发送业务请求是否被禁止，当该使能指示信息指示去使能该机制时，则终端设备不需要根据接入控制信息判断其发送业务请求是否被禁止，而是根据现在技术直接发送业务请求。进一步地，该使能指示信息可以是显示的指示信息，如ConnectionAccessEnable为Ture或Enable表示使能，其中ConnectionAccessEnable可以解释为连接态接入使能指示信息，即上述使能指示信息，或者ConnectionAccessEnable为False或Disable表示去使能。或者，该使能指示信息还可以是隐式的指示信息，如网络设备发送了与连接态接入控制相关的信息时，表示使能了上述连接态接入控制机制，若网络设备没有发送与连接态接入控制相关的信息时，则表示去使能上述连接态接入控制机制。需要说明的是，此处只是列举了第一接入控制信息可能的内容，并不是对第一接入控制信息内容的具体限定。在实际应用中，可以根据实际需求配置第一接入控制信息的内容。
允许发起的业务类型指的是网络设备允许连接态终端设备发起的业务的业务类型，例如，允许发起的业务类型可以包括以下一种或多种的组合，被叫业务(Mobile terminating call)、紧急呼叫业务(Emergency call)、主叫业务(Mobile originating call)、信令业务(Signalling)、电路域回退(CS fallback)、多媒体电话业务(Multi-Media Telephony,MMTEL)、语音业务(Voice)、视频业务(Video)、短信业务(Short Message Service,SMS)、时延容忍业务(Delay tolerance service)等。需要说明的是，上述对允许发起的业务类型的示例，并不构成限定。
禁止发起的业务类型指的是网络设备禁止连接态终端设备发起的业务的业务类型，例如，禁止发起的业务类型可以包括以下一种或多种的组合，被叫业务(Mobile terminating call)、紧急呼叫业务(Emergency call)、主叫业务(Mobile originating call)、信令业务(Signalling)、电路域回退(CS fallback)、多媒体电话业务(Multi-Media Telephony,MMTEL)、语音业务(Voice)、视频业务(Video)、短信业务(Short Message Service,SMS)、时延容忍业务(Delay tolerance service)等。需要说明的是，上述对禁止发起的业务类型的示例，并不构成限定。
示例性的，允许发起业务的终端设备类型可以是机器类型通信(Machine Type Communication,MTC)终端设备或窄带物联网(Narrow Band Internet of Thing,NB-IoT)终端设备或水表或电表或可穿戴设备等。需要说明的是，上述对允许发起业务的终端设备类型的示例，并不构成限定。
示例性的，禁止发起业务的终端设备类型可以是机器类型通信(Machine Type Communication,MTC)终端设备或窄带物联网(Narrow Band Internet of Thing,NB-IoT)终端设备或水表或电表或可穿戴设备等。需要说明的是，上述对禁止发起业务的终端设备类型的示例，并不构成限定。
使能接入控制策略的指示信息指的是网络设备指示终端设备根据指定的接入控制策略确定连接态时能否发起业务。其中，接入控制策略是预先配置或现在3GPP TS36.331中的接入控制准则。
示例性的，接入控制策略可以包括以下至少一项：ACB策略；或者，SSAC策略；或者，ACB skip策略；或者，EAB策略；或者，数据通信中的ACDC策略。
当然，在实际应用中，可以根据实际需求配置接入控制策略的内容，此处只是对接入控制策略的内容举例说明，并不是对此的具体限定。
其中，ACB策略是3GPP的Release8中提出的接入控制策略，终端设备使用一个随机数和一个定时器，基于接入的类型进行接入控制。
SSAC策略(Scheme/Mechanism)为3GPP的Release9中提出的接入控制策略，在该策略中，网络广播禁入因子和随机定时器，实际决策是在UE的IMS层，其适用于连接态和空闲态，用于解决因大量终端设备同时接入所引起的网络过载问题。
ACB skip策略为3GPP的Release12引入的用于控制IMS语音和视频用户忽略ACB策略的方法。
EAB策略为3GPP的Release11中提出的接入控制策略，在该策略中，准许网络禁止低优先级UE。该方法基于一个bitmap，0-9中的每个class可以被禁止或被准许。
数据通信中的ACDC策略为3GPP的Release13中提出的接入控制策略，在该策略中，准许禁止特定应用的业务，基于全球应用标识将应用分类，网络针对每类应用广播禁止参数(禁止因子和定时器)。
例如，使能接入控制策略的指示信息为AccessControlStrategy，一种方法是只指示一种策略，即使用枚举类型定义，如AccessControlStrategy为ENUMERATED{ACB，SSAC，ACBskip,EAB,ACDC，…}，当AccessControlStratey值为ACB时，终端设备根据该指示信息，使用现在技术中的ACB策略对终端设备在连接态打算发送的业务请求进行检查，检查是否符合ACB策略的接入控制，若检查结果为允许接入，则终端设备发送该业务请求，否则不发送该业务请求。另一种方法是网络设备指示一种或多种策略，可以使用AccessControlStrategyList来定义，其中AccessControlStrategyList由SEQUENCE(SIZE(0..maxValue))OF AccessControlStrategy定义，maxValue为网络允许的最大的策略个数，AccessControlStrategy的定义如前一种方法。或者，网络设备指示一种或多种策略还可以使用比特图(Bitmap)来定义，例如，假设一共5种策略，依次为ACB，SSAC，ACBskip，EAB，ACDC，则可以定义比特图AccessControlStrategyBitmap为BIT STRING(5)，即共5个比特，每个比特依次表示上述5种策略，某比特位为“1”时表示使能该策略，则终端设备需要根据该策略检查是否允许发送业务请求，某比特为“0”时表示去使能该策略，则终端设备不需要根据该策略检查是否允许发起业务。其中“1”和“0”的意义可以互换。例如，AccessControlStrategyBitmap为00110，则表示使能ACBskip，EAB策略，去使能其他策略。
可选的，在S501中，第一网络设备可以周期性的确定第一接入控制信息，也可以在其负载状况满足预设条件的时候确定第一接入控制信息，本申请实施例对于执行S501的时机不进行具体限定，可以根据实际需求配置。
其中，周期性确定第一接入控制信息时，周期的具体间隔可以根据实际需求配置；预设条件的内容也可以根据实际需求配置；本申请实施例对此均不进行具体限定。
可选的，在S501中，第一网络设备确定第一接入控制信息可以通过下述方案中任 一种实现：
方案1、第一网络设备根据自身负载状况确定第一接入控制信息。
可选的，在方案1中，可以预先配置负载状况与第一接入控制信息的内容的预设对应关系，在执行S501时，查询该预设对应关系即可。该预设对应关系的内容，可以根据实际经验配置，本申请对于配置过程不进行限定。
示例性的，如表1所示，示意了一种预设对应关系的内容。如表1所示，假设第一网络设备执行S501时，负载状态为15％，则确定第一接入控制信息的内容时，以第一接入控制信息包含禁止发起的业务类型为例，则禁止发起的业务类型可以为A类型业务、B类型业务。
表1
Figure PCTCN2018090309-appb-000001
需要说明的是，表1只是对预设对应关系的示例性说明，并不是对预设对应关系内容及形式的限定。
可选的，在方案1中，可以预先通过学习建立负载状况与第一接入控制信息的模型，当执行S501时，将负载状况输入模型中得到第一接入控制信息。
需要说明的是，对于根据负载状况确定第一接入控制信息的过程，还可以采用其他方式，本申请实施例对此不进行具体限定。
方案2、第一网络设备接收第二网络设备发送的第二接入控制信息，根据第二接入控制信息确定第一接入控制信息。其中，第二接入控制信息由第二网络设备根据第一网络设备的负载状况确定。
可选的，在方案2中，如图6所示，在S501之前，本申请实施例提供的发送业务请求的方法还可以包括S501a至S501e。
S501a、第一网络设备向第二网络设备发送指示负载状况的负载指示信息。
其中，负载指示信息用于指示第一网络设备的负载状况，负载指示信息可以为字符串、代码等任何形式，本申请实施例对此不进行具体限定。需要说明的是，负载指示信息与负载状况的对应关系，可以根据实际需求配置，本申请实施例对此不进行具体限定。
示例性的，负载指示信息可以用二进制字符串表示，负载指示信息与负载状况的对应关系可以用对应关系的形式体现，执行S501a时查询对应关系获取负载指示信息并发送。
S501b、第二网络设备从第一网络设备接收负载指示信息。
S501c、第二网络设备确定第二接入控制信息。
其中，第二网络设备根据S501b中接收的负载指示信息，确定第二接入控制信息。
在一种可能的实现方式中，第二网络设备可以根据负载指示信息直接确定第二接 入控制信息。第二网络设备根据负载指示信息确定第二接入控制信息的实现方式，可以参考方案1中第一网络设备根据负载状况确定第一接入控制信息的实现方式，此处不再进行赘述。
在另一种可能的实现方式中，第二网络设备根据负载指示信息确定负载状况，再根据负载状况确定第二接入控制信息，第二网络设备根据负载状况确定第二接入控制信息的实现方式，可以参考方案1中第一网络设备根据负载状况确定第一接入控制信息的实现方式，此处不再进行赘述。
需要说明的是，第二接入控制信息的内容可以和第一接入控制信息的内容完全相同，或者，第二接入控制信息的内容可以与第一接入控制信息的内容对应，本申请实施例对此不进行具体限定。
S501d、第二网络设备向第一网络设备发送第二接入控制信息。
第二网络设备通过其与第一网络设备的通信接口，传输第二接入控制信息。
S501e、第一网络设备从第二网络设备接收第二接入控制信息。
方案3：第一网络设备接收第二网络设备发送的第二接入控制信息，根据第二接入控制信息确定第一接入控制信息。其中，第二接入控制信息由第二网络设备的自身的负载状况确定。
具体的，将方案2中的S501a至S5-1e替换为S501c、S502d、S501e，即可实现方案3。
一种实现方式是，第二网络设备根据自身的负载状况确定第二接入控制信息，第二接入控制信息可以是显示的类似于第一接入控制信息，或是第二接入控制信息用于指示第二网络设备的负载状况，第一网络设备根据第二接入控制信息指示的第二网络设备的负载状况确定第一接入控制信息。
需要说明的是，本文中，所有网络设备“根据A确定B”中的“根据A”都是可选内容，即网络设备也可以根据其他信息来确定。
在方案2或者方案3中，S501的具体实现可以包括但不限于下述实现1和实现2。
实现1：第二接入控制信息与第一接入控制信息相同，第一网络设备接收到第二接入控制信息即可确定出第一接入控制信息。在实现1中，第一网络设备接收到第二网络设备确定的第二接入控制信息，直接得到第一接入控制信息。此时，第二接入控制信息可以直接通过第一网络设备发送到终端设备，即将第二接入控制信息封装进第一接入控制信息发送至终端设备。
实现2、第二接入控制信息与第一接入控制信息相对应，第一网络设备接收到第二接入控制信息后，根据对应关系确定出第一接入控制信息。例如，第一网络设备根据第二接入控制信息及第一网络设备与终端设备之间的通信协议确定第一接入控制信息，此时第一接入控制信息与第二接入控制信息只有数据传输格式上的区别，其实质意义相同，即第一网络设备将第二接入控制信息重新封装成第一接入控制信息发送至终端设备。
需要说明的是，在S501中描述的根据第一网络设备的负载状况确定第一接入控制信息，在实际应用中，也可以根据其他网络设备的负载状况确定第一接入控制信息，具体实现相同，此处不再进行赘述。
S502、第一网络设备发送第一接入控制信息。
具体的，在S502中第一网络设备发送第一接入控制信息，可以通过但不限于下述两种实现方式：
第一种实现方式：系统消息(system information)，该系统消息包括第一接入控制信息。

示例性的，服务请求可以为浏览网页的服务请求，或者，拨打电话的服务请求，或者其他，本申请对此不进行赘述。
另一种可能的实现中，在S503中AS层从第一网络设备接收第一接入控制信息并保存，NAS层在连接态向AS层发送第一业务的业务请求的信令及接入控制策略指示信息，AS层参照接入控制策略指示信息所指示的接入控制策略，根据第一接入控制信息和第一业务请求的信令判断第一业务是否被禁止接入。其中，接入控制策略指示信息所指示的接入控制策略为配置在终端设备内部的接入控制策略，其与第一接入控制信息结合起来对终端设备发起的业务的接入进行控制。此处描述的接入控制策略指示信息所指示的接入控制策略与前面描述的接入控制策略相同，前面已经对接入控制策略进行了详细描述，此处不再进行赘述。
例如，NAS层在连接态向AS层发送MO业务请求的信令及ACB策略指示信息，则AS层针对MO业务请求检查ACB策略是否允许MO业务请求的发起。
在一种可能的实现中，AS层根据第一接入控制信息和第一业务的业务请求信令判断第一业务是否被禁止接入，具体可以包括：AS层解析第一业务的业务请求信令，获取第一业务的业务类型；AS层根据第一接入控制信息和第一业务的业务类型判断第一业务是否被禁止接入。
在另一种可能的实现中，NAS层在连接态向AS层发送第一业务的业务请求信令时，还向AS层发送了第一业务的业务类型。AS层根据第一接入控制信息和第一业务的业务请求信令判断第一业务是否被禁止接入，包括：AS层根据第一接入控制信息和第一业务的业务类型判断第一业务是否被禁止接入。
需要说明的是，由于第一接入控制信息指示了哪些业务被禁止接入或者哪些业务未被禁止接入，因此确定第一业务是否被禁止接入的过程就是比对的过程，此处不再进行一一赘述。
S504、在连接态时，若第一接入控制信息指示第一业务被禁止接入，终端设备停止向第一网络设备发送第一业务的业务请求。
进一步的，当终端设备包括AS层和NAS层时，S504的具体实现可以有多种，下面一一描述。
在一种可能的实现中，由NAS层根据第一接入控制信息确定第一业务在连接态被禁止接入，终端设备停止向第一网络设备发送第一业务的业务请求，具体可以实现为：NAS层停止向AS层发送第一业务的业务请求信令。
在另一种可能的实现中，NAS层在连接态向AS层发送第一业务的业务请求的信令，由AS层根据第一接入控制信息确定第一业务在连接态被禁止接入，终端设备停 止向第一网络设备发送第一业务的业务请求，具体可以实现为：AS层停止向第一网络设备发送第一业务的业务请求信令。
可选的，在另一种可能的实现中，当AS层判断第一业务被禁止接入时，本申请提供的发送业务请求的方法还可以包括：AS层向NAS层发送响应信息，该响应信息指示第一业务被禁止接入。
可选的，在另一种可能的实现方式中，本申请提供的发送业务请求的方法还可以包括：AS层向NAS层发送响应信息时，向NAS层发送第一业务被禁止接入的原因，原因可以包括是因为ACB或ACDC等策略的检查结果为禁止。
通过本申请提供的发送业务请求的方法，根据从第一网络设备接收的第一接入控制信息的指示第一业务被禁止接入，终端设备连接态时停止向第一网络设备发送第一业务的业务请求，控制了终端设备在连接态时的业务接入，进而控制了第一网络设备的负载，避免过载影响网络服务质量。
进一步的，如图6所示，在S503a之后，本申请提供的发送业务请求的方法还可以包括S505。
S505、在连接态时，若第一业务未被禁止接入，终端设备向第一网络设备发送第一业务的业务请求。
进一步的，当终端设备包括AS层和NAS层时，S505的具体实现可以有多种，下面一一描述。
在一种可能的实现中，由NAS层根据第一接入控制信息确定第一业务在连接态未被禁止接入，终端设备向第一网络设备发送第一业务的业务请求，具体可以实现为：NAS层向AS层发送第一业务的业务请求信令，AS层向第一网络设备发送第一业务的业务请求信令。
在另一种可能的实现中，NAS层在连接态向AS层发送第一业务的业务请求的信令，由AS层根据第一接入控制信息确定第一业务在连接态未被禁止接入，终端设备向第一网络设备发送第一业务的业务请求，具体可以实现为：AS层向第一网络设备发送第一业务的业务请求信令。
