- the services in the current LTE protocol are mostly transmitted by using the CP mode.
- a UE that receives the rule only needs to initiate a non-IP-data service, and no matter what its capabilities are, no matter what access method it uses, it cannot initiate access;
- the access restriction condition of the rule for the non-IP-data service is more relaxed than the rule (8), and the access restriction is performed on a part of the non-IP-data service from the perspective of the service data feature.
- the limitation angle of the service data feature includes one or more of the following combinations:
- Example 12 Selection rule (10) or (11) can refer to rule (8) or (9);
- the threshold can be notified by the network side.
- the UE is preset by the transmitting and receiving parties;
- the rule combines the restriction conditions of the service data feature with the restriction conditions of the access method, and the usage can refer to the previous rule with the restriction condition of the CP scheme and the restriction condition of the service data feature.
- the rule also combines the restriction conditions of the service data feature with the restriction conditions of the access method, except that the restriction condition of the access method is for the UP mode, and thus the constraint conditions and rules (13) of the corresponding service data feature are Differently, this example emphasizes that the UP scheme cannot be used to transmit small packets or low-traffic services.
- the eNB When the eNB sends the above rules, one of them may be selected, or multiple of them may be selected. When selecting multiple rules, it should be ensured that there is no conflict between the rules, and there is no overlapping part.
- This example is used to illustrate a more flexible access restriction method that can be formed by combining additional restriction parameters.
- the eNB may additionally send other restriction parameters to cooperate with the access restriction rule to form a new and more flexible access restriction rule.
- the additional restriction parameters include:
- - Proportion parameter increasing the probability factor or the scale factor to specify the probability that the access restriction rule is effective or the proportion of the UE;
- - data model threshold increasing the packet size threshold, or the accumulated data volume threshold, or the traffic threshold, or the number of consecutive packets, or the frequency/period threshold of consecutive packets to specify that the access restriction rule includes The business is prohibited from exceeding the data model threshold, or is prohibited from being lower than the data model threshold;
- the above three parameters may be selected by one parameter or a combination of multiple parameters, and combined with the aforementioned access restriction rule to form a new rule.
- the specific values of the above three parameters may be configured by the eNB and notified to the UE by broadcast messages or paging, or dedicated signaling.
- Example 1 Combining rule (2) "Prohibiting the use of CP mode to initiate mo-ExceptionData, or delayTolerantAccess, or mo-signaling call" with the time parameter, can form a new rule as follows:
- the time range A may be configured by the eNB and notified to the UE by a broadcast message or dedicated signaling.
- Example 2 Combining rule (2) "Prohibiting the use of CP mode to initiate mo-ExceptionData, or delayTolerantAccess, or mo-signaling call" with the proportional parameter, can form a new rule as follows:
- the preset ratio B may be configured by the eNB and notified to the UE by using a broadcast message or dedicated signaling. In this way, the eNB can prohibit the number of users in the proportion B from using the CP mode to initiate a call of the restricted service type.
- Example 3 Combining rule (2) "prohibiting the use of CP mode to initiate mo-ExceptionData, or delayTolerantAccess, or mo-signaling call" with the data model threshold, wherein the data model threshold in turn includes a packet size threshold, or accumulated data
- the threshold, or the traffic threshold, or the threshold of the number of consecutive packets, or the frequency/period threshold of consecutive packets, may be selected one or more.
- New rules can be formed as follows:
- Example 4 The rule “prohibit sending non-IP-data services” is combined with time parameters, proportional parameters, and data model thresholds to form new rules as follows:
- the number of users of the preset ratio B is prohibited from transmitting non-IP-data services exceeding the traffic threshold;
- This example is used to describe the relationship between the access restriction rules and restriction parameters of the present invention and the existing LTE Access Barring (ACB) and (Extended Access Barring, EAB).
- ACB existing LTE Access Barring
- EAB Extended Access Barring
- the existing LTE has the ACB and the EAB mechanism, and the parameters are all sent by the system broadcast message SIB2.
- the access restriction rule and the restriction parameter of the present invention are in a parallel relationship with the ACB or the EAB, and the following two methods are used to process the two. relationship:
- the UE After the UE obtains the ACB parameter and the EAB parameter, and the access restriction rule and the restriction parameter in the embodiment of the present invention, the UE first performs the determination of the access restriction rule and the restriction parameter according to the present invention, and if the UE passes the judgment, The UE needs to perform the ACB parameter or the EAB parameter again;

以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细阐述,应当理解,以下所说明的优选实施例仅用于说明和解释本发明,并不用于限定本发明。
如图1所示,本实施例提供一种接入控制方法,包括:
步骤S110:当核心网或接入网的网络负载符合过载条件,或所述核心网或接入网的拥塞状况符合拥塞条件时,接入网网元向用户设备UE发送接入限制规则的指示信息;
其中,所述接入限制规则包括以下至少之一:
禁止UE使用的接入方式;
禁止接入的UE类型;
禁止接入的业务类型。
本实施例所述的提供的接入控制方法,为应用于网络侧的方法,例如,应用于接入网的网元中的方法,例如,演进型基站(evolution Node B,eNB)中的方法。该接入网网元可为所述eNB或下一代基站(next generation Node B,gNB)或,其他无线接入节点(Access Point,AP)等。在本实施例中,所述接入网可以由接入网网元相互连接而成。所述接入网网元除了基站、AP,还可以包括各种位于接入网中的中继节点(Relay Node,RN)等其他节点。
在本实施例中所述步骤S110可包括:
步骤S111:当核心网或接入网的网络负载符合过载条件,或所述核心网或接入网的拥塞状况符合拥塞条件时,获取与所述接入网或核心网的过载状况或拥塞状况,相适配的指示信息;总之,所述步骤S110可为:预定网络的网络负载符合过载条件,或者,预定网络的拥塞状况服务拥塞条件,则需要生成或接收与当前过载状况或拥塞状况相适配的指示信息。这里的预定网络为所述核心网和/或所述接入网。
步骤S112:将所述指示信息发送给UE。
获取所述指示信息的方式,可以是2所述接入网网元,自身根据接入网或核心网的负载状况或拥塞状况,自行产生所述指示信息,也可以是从核心网的网元接收,例如,从移动管理实体(Mobility Management Entity, MME)接收。
例如,形成所述指示信息的网元中预先设定有,负载率或拥塞状况与对应的指示信息的对应关系,在形成需要下发给UE的指示信息时,以当前的负载率及拥塞状况等信息,查询所述对应关系,选择所述对应关系中与负载率及拥塞状况等信息匹配的指示信息,作为当前需要下发给UE的指示信息。当然产生所述指示信息的方式有多种,不局限于上述举例。
当核心网或接入网的网络负载符合预设条件可包括:当接入网或核心网的负载率达到负载率门限或负载量超过负载量门限时,可认为所述核心网或接入网的网络负载符合所述过载条件。在本实施例中判断所述核心网的网络负荷,可包括判断MME的当前负载率或当前负载量是否达到对应的门限。所述接入网的网络负荷符合所述过载条件,可包括:判断基站的当前负载率或负载量是否达到对应的门限。
所述核心网或接入网的拥塞状况,可以用当前核心网或接入网的负载状况来表示,也可以根据当前网络的可用资源状况或待响应请求的数量等参数来表征所述拥塞状况,当拥塞状况满足一定的条件时,可认为核心网或接入网络发生拥塞,需要缓解拥塞。例如,当前MME或eNB队列中的待响应的请求数量超过数量阈值,或,当前MME或eNB的处理资源的使用率达到使用率上限等,即可认为出现了拥塞,符合上述拥塞条件。
此时,所述接入网网元通过广播消息向该接入网网元覆盖的所有UE发送指示信息。该指示信息可用于指示接入限制规则的生效或执行。
在本实施例中接入网网元向UE发送指示信息,可通过广播消息或非广播消息发送所述UE。
所述广播消息可包括***消息。所述指示信息可以携带在***消息的主设备信息块(Master Information Block,MIB)或***信息块(System Information Block,SIB)中发送给UE。
在本实施例中所述指示信息指示的接入限制规则可包括:
禁止UE接入时使用的接入方式;
禁止接入的UE的类型,这种类型,可以由UE的UE能力来进行区分,可为:指示具有哪些UE能力的UE禁止接入。
禁止接入的业务类型。
所述禁止UE接入时使用的接入方式、禁止接入的UE的类型及禁止计入的业务类型,都可以视为接入限制规则的限制参数。
所述指示信息指示的接入限制规则可包括:一个或多个限制参数组合形成的。此时,在一种实施例中,当所述接入限制规则包括两个或两个以上的限制参数时,则该条接入限制规制为:同时满足该条接入限制规则的两个或两个以上的接入限制参数的UE禁止接入。
例1,某一个接入限制规则包括:限制参数为两个,且分别是:禁止UE接入时使用的接入方式及禁止接入的业务类型;则表示禁止使用对应方式发起对应业务类型的呼叫。
例2,当所述接入限制规则包括两个或两个以上的限制参数时,则该条接入限制规制为:只要满足其中一个限制参数的UE就禁止接入,某一个接入限制规则包括:限制参数为两个,且分别是:禁止UE接入时使用的接入方式及禁止接入的业务类型,则可表示禁止对应类型的UE发起的任意业务的呼叫,且同时禁止任何UE使用任何方式发起对应业务类型的呼叫。
故在一些实施例中,当所述接入限制规则包括两个或两个以上的限制参数时,根据限制参数的组合方式,组合所述限制参数形成具体接入限制规则。这里的组合方式,至少包括:例1中的第一组合方式,和例2中的第二组合方式。
在一些实施例中,所述限制参数还可包括:时间参数、比例参数及模型参数中的一个或多个。
所述指示信息可分为三类指示比特,分别是第一类指示比特、第二类指示比特和第三类指示比特;所述第一类指示比特中的一个或多个比特用于指示禁止接入的接入方式,第二类指示比特用于指示禁止接入的UE类型;所述第三类指示比特用于指示禁止接入的业务类型。在本实施例中将指示信息对应的指示比特拆分成三种类型进行表征,这样的话,在进行接入限制规则的生效时,可以通过至少两类指示比特的组合,可以灵活的组合出符合当前网络状况的接入限制规则的执行。且通过指示信息的发送,指示当前生效的接入限制规则,而并非完整的接入限制规则的发送,具有信令开销小,且灵活度高的特点。
UE在接收到所述指示信息之后,知道哪些限制接入规则当前生效,在发起接入之前,需要根据当期生效的接入限制规则,确定自身是否被允许发起接入。
在一些实施例中,所述禁止UE使用接入方式包括以下至少之一:
控制面优化数据传输CP方式;
用户面优化数据传输UP方式;
无线资源控制连接建立legacy方式;
所述禁止接入的UE类型包括以下至少之一:
仅支持所述CP方式接入的UE;
同时支持所述CP方式和所述UP方式进入的UE;
所述禁止接入的业务类型包括以下至少之一:
主叫数据业务mo-data;
主叫超常数据mo-Exception Data;
延时容忍接入业务Delay Tolerant Access;
主叫信令业务mo-signaling;
网络协议IP数据业务;
非IP数据业务。
所述CP方式包括:终端通过控制面信令,例如,非接入层(Non-access stratum,NAS)消息,将数据直接传送给MME,由MME将数据转发个外网,而不是通过网关将数据转发给外网的接入方式。CP方式需要MME参与数据的传输,若CP方式接入的UE过多,可能会导致MME的过载或拥塞。
所述UP方式为:UE和网络侧的连接释放之前,网络侧将保存UE的历史上下文,在终端下一次发起和网络侧连接时,利用保存过的上下文来建立连接的接入方式。该接入方式,需要基站等接入网网元存储上下文,若接入的UE过多或保存的上下文过多,会导致出现缓存资源减少,在下次接入时,可能还需要检索前一次保存的上下文,还需要消耗一定的处理资源。这里的处理资源可包括处理器或处理电路提供的计算、查询及检索等资源。
所述legacy方式为利用RRC信令建立连接的方式。
所述mo-exception data通常指向的为突发类型的业务,例如,报警业务、异常类型的数据上报业务等。
所述网络协议IP数据业务可以简称为non-IP-data业务;所述网络协议IP数据业务可以称之为IP-data业务。通常non-IP-data业务对应的数据包中不携带有目的IP地址,采用的非基于目的IP地址的路由转发。所述IP-data业务对应的数据包时携带有目的IP地址。
针对上述CP方式的限制,通常当核心网的网络负荷符合所述过载条件或核心网的拥塞状况负荷所述拥塞条件时,尤其是当所述MME的当前状况负荷所述过载条件或所述拥塞条件时,所述接入网网元发送的所述指示信息,可用于指示禁止部分或全部终端采用CP方式发起接入,或指示全部或部分业务采用CP方式发起接入的接入限制规则生效,从而缓解核心网的过 载或拥塞状况。
针对上述UP方式的限制,通常当接入网的网络负荷符合所述过载条件或接入网的拥塞状况符合所述拥塞条件时,尤其是基站的剩余缓存小于缓存阈值,或缓存出现紧张、或者剩余处理资源小于处理资源阈值等情况时,所述接入网网元发送的指示信息,用于指示禁止全部或部分终端采用UP方式接入或,全部或部分业务采用UP方式接入的接入限制规则生效,从而缓解接入网的过载或拥塞状况。
在本实施例中所述UE的类型,是根据UE支持的接入方式的UE能力来确定的。例如,所述UE可以分为仅支持CP方式的一类UE,同时支持CP方式和UP方式的另一类UE。
所述指示信息,可以指示对应的接入限制规则生效,从而限制某一类UE的接入。例如,接入网网元可以通过第二类指示比特,在核心网出现拥塞或过载时,指示禁止仅支持CP方式的UE进入的接入限制规则生效。再例如,接入网网元可以通过第二类比特,在接入网出现拥塞或过载时,指示禁止同时支持CP方式和UP方式的UE进行接入,或指示同时CP方式和UP方式的UE采用CP方式接入。
可选地,所述指示信息指示生效的接入限制规则可包括以下至少之一:
规则1:禁止使用UP方式或者legacy方式发起主叫数据业务mo-data、所述主叫超常数据mo-ExceptionData、延时容忍接入业务delayTolerantAccess、或者主叫信令业务mo-signaling的呼叫;该规则1又可以分为:

禁止同时支持CP方式和UP方式的UE,使用UP方式发起所述mo-data、或者所述mo-ExceptionData、所述delayTolerantAccess或者所述mo-signaling的呼叫;
规则8:禁止发送非网络协议数据non-IP-data业务;
规则9:禁止发送单个数据包超过第一预设数据包长度门限的所述non-IP-data业务、一次连接累积发送数据量大于第一累积门限的所述 non-IP-data业务、流量超过第一预设流量门限的所述non-IP-data业务、或者具有连续数据包的所述non-IP-data业务,其中,所述具有连续数据包的所述non-IP-data业务为:通过一次连接发送多个数据包的所述non-IP-data业务;
规则10:禁止发送网络协议数据IP-data业务;
规则11:禁止发送单个数据包超过第二预设数据包长度门限的所述IP-data业务、一次连接累积数据量大于第二累积门限的所述IP-data业务、流量超过第二预设流量门限的所述IP-data业务;
规则12:禁止使用CP方式发起超过第三预设数据包长度门限的业务、一次连接累积数据量超过第三累积门限的业务、流量超过第三预设流量门限的业务,或者具有连续数据包的业务;
规则13:禁止使用UP方式发起低于第四预设数据包长度门限的业务、一次连接累积数据量低于第四累积门限的业务、或者流量低于第四预设流量门限的业务。
上述预设数据包长度门限、累积门限之前的“第一”、“第二”及“第三”等序数词都是用于区分不同情况下的门限,并不代表实质的意义。
在本实施例中所述接入网网元,可以根据当前发送拥塞状况或过载现象的位置,及根据所述接入限制规则的限制接入的效果,指示对应的接入限制规则生效。
在本实施例中前述多条限制接入规则可为预先存储在UE和接入网网元中,也可以为UE和接入网网元预先协商的,也可以是通信协议预先规定的。总之,在发送所述指示信息之前,所述接入网网元和所述UE都可以有相应的途径获取上述接入限制规则,并获得指示信息与接入限制规则之间的对应关系,从而可以方便后续UE根据指示信息,执行或生效那一条具体的接入限制规则的执行,从而实现接入控制,缓解大量的UE,尤其是物联 网终端同时接入网络导致的过载或拥塞。
例如,当所述指示信息指示规则3生效时,UE在发起接入之前,会随机产生一个0到1之间的随机数,将随机数与所述预定比例进行比较,若该随机数大于所述预定比例,则允许该UE发起接入,否则禁止该UE发起接入。当然,也可以是若所述随机数不大于所述预定笔试时,允许UE发起接入,否则禁止UE接入。
以上仅是接入限制规则的举例,但是具体实现时不局限于上述任意一条规则。
这里的规则1至规则13可为前述的具体接入限制规则。
在本实施例中所述接入限制规则可分为两部分,第一部分为规则内容,第二部分为规则执行的限制参数。所述限制参数可包括时间参数、比例参数及数据模型参数中的一个或多个,当然具体实现时,还可包括例外参数等。这里的例外参数可至少哪些特殊情况对应规则内容不生效的情况。可选地,所述接入限制规则还包括时间参数、比例参数及数据模型参数的至少其中之一;
所述时间参数,用于规定所述接入限制规则的生效时长;
所述比例参数,用于指示限制接入的用户设备的比例或所述接入限制规则的生效概率;
所述数据模型参数,包括:数据模型门限;
所述数据模型门限包括以下至少之一;
数据包长度门限;
累积数据量的累积门限;
流量门限;
连续数据包的数据个数门限;
连续数据包的发送频次或周期门限。
所述生效时长对应于的一个时间窗口的时间长度。若UE接收到指示信息之后,读取了某一条接入限制规则的规则内容,同时提取了时间参数,根据时间参数中限制的生效时长,可以从接收到指示信息时刻开始或读取到接入限制规则开始,计算生效时间。所述比例参数,指示的某一条或多条规则的生效概率或用户终端的比例。当所述比例参数为限制接入的UE的比例时,所述UE可以通过产生随机数的方式,然后将随机数与比例进行比较,然后确定当前是否发起接入请求。
在本实施例中所述限制参数可为单独写在每一个条接入限制规则中,该一个所述限制参数也可以同时被多条限制规则共用。例如,所述时间参数可为被多条接入限制规则共用的参数。该时间参数可以由所述基站发送给UE,也可以是基站向UE指示。
所述步骤S110还可包括:
所述接入网网元向所述UE通过广播消息发送所述指示信息,其中,所述广播消息包括:***消息。
在另一些实施例中,所述步骤S110可包括:
所述接入网网元通过寻呼消息、物理下行控制信道或专用RRC信令发送所述指示信息。
在本实施例中优选采用广播消息发送所述指示信息,从而一次性指示多个UE的接入控制。暂时还未发起接入请求的,则会根据所述指示信息控制自身的接入请求的发起。
总之,所述接入网网元向UE下发所述指示信息的方式有多种,不局限于上述任意一种。
如图2所示,本实施例提供一种接入控制方法,包括:
步骤S210:接收接入网网元发送的指示信息,其中,所述指示信息用于指示接入限制规则,所述接入限制规则包括以下至少之一:

步骤S220:根据所述指示信息指向的所述接入限制规则,确定是否发起接入。
本实施例所述的方法可为应用于UE中的方法。所述接入网网元可为任意可以使得基站连接到无线网络的通信节点,例如,各种类型的基站等。
在步骤S210中接收接入网网元发送的指示信息,这里的指示信息的相关描述可以参见前述实施例的对应部分。在步骤S210招工可包括接收广播发送的指示信息、组播发送的指示信息或单播方式的指示信息。优选为,接收接入网网元广播方式的指示信息。
例如,所述步骤S210可包括:
接收广播信息,从广播信息中提取所述指示信息;这里的广播信息可包括***消息。所述指示信息可携带在SIB或MIB中发送给UE。
接收寻呼消息或物理下行控制信道发送的消息或专有RRC信令携带的所述指示信息。
在本实施例中所述指示信息,可用于分别指示禁止UE接入的接入方式、禁止接入的UE类型及禁止接入的业务类型的一种。故在本实施例中同样的,所述指示信息可包括前述三类的指示比特。

在本实施例中上述接入方式、数据类型的相关定义可以参见前述实施例,在此就不重复描述了。
进一步地,所述接入限制规则至少包括以下之一:

禁止同时支持CP方式和UP方式的UE使用CP方式发起所述mo-data、所述mo-ExceptionData、所述delayTolerantAccess或者所述mo-signaling的呼叫;
禁止同时支持CP方式和UP方式的UE,使用UP方式或者legacy方 式发起所述mo-data、或者所述mo-ExceptionData、所述delayTolerantAccess或者所述mo-signaling的呼叫;
禁止发送非网络协议数据non-IP-data业务;
禁止发送单个数据包超过第一预设数据包长度门限的所述non-IP-data业务、一次连接累积发送数据量大于第一累积门限的所述non-IP-data业务、流量超过第一预设流量门限的所述non-IP-data业务、或者具有连续数据包的所述non-IP-data业务,其中,所述具有连续数据包的所述non-IP-data业务为:通过一次连接发送多个数据包的所述non-IP-data业务;

此处接收的接入限制规则与基站等接入网网元发送的接入限制规则是一致的。
进一步地,所述接入限制规则还包括时间参数、比例参数及数据模型参数的至少其中之一;所述时间参数,用于规定所述接入限制规则的生效时长;所述比例参数,用于指示限制接入的用户设备的比例或所述接入限制规则的生效概率;

通过上述参数的限定,可以规定接入限制规则的生效时间、生效概率及生效模型等各种参数,可以确保进一步的控制接入限制规则的使用,从而更好的限制UE,尤其是物联网UE的接入,从而可以网络侧减少拥塞和过载的现象。
以下结合上述实施例提供几个具体示例:
示例1:
本示例用来说明由无线接入网自己发起的接入限制流程。
本示例采用LTE接入网作为例子,其无线接入网网元为eNB。
如图3所示:
步骤101:eNB判断自己的负荷等级是否为高或者过载,如果是,则eNB发起对终端的接入限制,eNB通过SIB广播或者通过寻呼信道将接入限制规则和或限制参数发送给UE。
步骤102:UE在发起接入之前,获取eNB发送的接入限制规则和/或限制参数;
步骤103:UE根据收到所述的接入限制规则和或限制参数判断能否发起接入行为。
示例2:
本示例用来说明不同的接入限制指示的组合可以形成哪些接入限制方法和效果。
本实施具体说明在示例1中,eNB在SIB、或者寻呼消息、或者RRC专用信令中包含的接入限制规则和或限制参数可以包括哪些方式,起到怎样的接入控制效果;
将本示例和示例1进行结合,就可以形成包括接入控制流程和接入控制参数的完整详细的示例子。
eNB在SIB、或者寻呼消息、或者RRC专用信令中包含的接入限制规则和或限制参数包括下面几类:
(1)禁止使用UP方式或者legacy方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(2)禁止使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(3)禁止一定比例X的UE(用户设备)使用CP方式发起mo-data的呼叫;
(4)禁止设备能力为“只支持CP方式”的UE发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(5)禁止设备能力为“同时支持CP方式和UP方式”的UE发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(6)禁止设备能力为“同时支持CP方式和UP方式”的UE使用CP方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(7)禁止设备能力为“同时支持CP方式和UP方式”的UE使用UP方式或者legacy方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
(8)禁止发送non-IP-data业务;
(9)禁止发送超过预设数据包大小门限的non-IP-data业务、或者超过累积数据量门限的non-IP-data业务、或者超过预设流量门限的non-IP-data业务、或者具有连续数据包的non-IP-data业务;
(10)禁止发送IP-data业务;
(11)禁止发送超过预设数据包大小门限的IP-data业务、或者超过累积数据量门限的IP-data业务、或者超过预设流量门限的IP-data业务;
(12)禁止使用CP方案发起超过预设数据包大小门限的业务、或者超过累积数据量门限的业务、或者超过预设流量门限的业务,或者具有连续数据包的业务,所述的门限可以由网络侧通知UE或者由收发双方预设置;
(13)禁止使用UP方案发起低于预设数据包大小门限的业务、或者低于累积数据量门限的业务、或者低于预设流量门限的业务(指禁止使用UP方式发送小数据/小流量业务,因为UP方案适合用于传输大数据/大流量)。
eNB根据自己负荷情况的严重等级,以及导致负荷的主要原因,在上述接入限制规则中选择1类规则,或者选择多种无相互冲突的规则;例如下面的例子:
以选择1种规则为例:
例1:选择规则(1),选择的受限业务类型为delayTolerantAccess,则eNB在RRC连接拒绝信令、RRC连接重建拒绝信令或者RRC连接释放信令中包含下述指示:
禁止使用UP方式或者legacy方式发起delayTolerantAccess的呼叫;
收到上述指示的UE,当其发起delayTolerantAccess的业务时,需根据指示的接入限制规则,只能使用除UP方式和legacy方式以外的方法 来发起接入;
例2:仍然选择规则(1),选择的受限业务类型为mo-data和delayTolerantAccess,则eNB在RRC连接拒绝信令、RRC连接重建拒绝信令或者RRC连接释放信令中包含下述指示:
禁止使用UP方式或者legacy方式发起mo-data、或者delayTolerantAccess的呼叫;
收到上述指示的UE,当其发起delayTolerantAccess的业务或者mo-data的业务时,需根据指示的接入限制规则,只能使用除UP方式和legacy方式以外的方法来发起接入。
例3:仍然选择规则(1),选择的受限业务类型为mo-ExceptionData和mo-signaling,以及mo-data和delayTolerantAccess,则eNB在RRC连接拒绝信令、RRC连接重建拒绝信令或者RRC连接释放信令中包含下述指示:
禁止使用UP方式或者legacy方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
收到上述指示的UE,当其发起规则所限制的上述4种业务时,只能使用除UP方式和legacy方式以外的方法来发起接入。
例4:规则2的用法可参考规则1,见例1,2,3;
例5:选择规则(3),选择的受限业务类型为mo-data,则eNB在RRC连接拒绝信令、RRC连接重建拒绝信令或者RRC连接释放信令中包含下述指示:
禁止一定比例X的UE(用户设备)使用CP方式发起mo-data的呼叫;所述比例X可以由eNB配置,通过广播消息或者专用信令通知UE,例如:当负荷较重时,可以将比例X设置得较高,例如80%。
收到上述指示的UE,当其发起规则所限制的mo-data业务时,如果 采用CP方式以外的其他方法,可以直接发起接入,如果采用CP方式,则需要按照均匀分布随机数来计算自己可以发起接入的概率,当比例X为80%时,只有20%的概率能使用CP方式来发起接入。
例6:选择规则(4)
禁止设备能力为“只支持CP方式”的UE发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫。
该规则对UE具有的能力种类以及发起的业务类型都进行了限制,除了能力限制外,业务的限制可以选择多种自由组合,例如:
禁止设备能力为“只支持CP方式”的UE发起mo-data的呼叫;
禁止设备能力为“只支持CP方式”的UE发起delayTolerantAccess的呼叫;
禁止设备能力为“只支持CP方式”的UE发起mo-ExceptionData或者mo-signaling的呼叫;
禁止设备能力为“只支持CP方式”的UE发起mo-signaling的呼叫;
例7:选择规则(5)
禁止设备能力为“同时支持CP方式和UP方式”的UE发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫。该规则设定了对另一种UE能力的接入限制;用法可参考例6;
例8:选择规则(6)
禁止设备能力为“同时支持CP方式和UP方式”的UE使用CP方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫。
该规则包含对UE能力、使用的接入方法、以及发起的业务类型的3种限制条件,使用方法可参考前面的例子;
例9:选择规则(7)
禁止设备能力为“同时支持CP方式和UP方式”的UE使用UP方式或者legacy方式发起mo-data、或者mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
和规则6类似,只是在对使用的接入方法的限制条件不同;
例10:选择规则(8)
禁止发送non-IP-data业务;
该规则仅对业务类型进行限制接入,而且针对的是非基于IP地址传输技术的业务,该类业务在目前的LTE协议中多采用CP方式来进行传输。
收到该规则的UE只要发起的是non-IP-data业务,无论其能力是什么、无论其采用什么接入方法,均不能发起接入;
例11:选择规则(9)
禁止发送超过预设数据包大小门限的non-IP-data业务、或者超过累积数据量门限的non-IP-data业务、或者超过预设流量门限的non-IP-data业务、或者具有连续数据包的non-IP-data业务
该规则对non-IP-data业务的接入限制条件相对于规则(8)更宽松一些,从业务数据特征的角度对non-IP-data业务的一部分做了限制接入。其中业务数据特征的限制角度包括下面的一种或者多种的组合:
禁止超过预设数据包大小门限;
禁止超过累积数据量门限;
禁止超过预设流量门限;
禁止具有连续数据包;
例12:选择规则(10)或(11)可参考规则(8)或(9);
例13:选择规则(12):
禁止使用CP方案发起超过预设数据包大小门限的业务、或者超过 累积数据量门限的业务、或者超过预设流量门限的业务,或者具有连续数据包的业务,所述的门限可以由网络侧通知UE或者由收发双方预设置;
该规则将业务数据特征的限制条件与接入方法的限制条件进行了结合,其用法可参考前面的有CP方案限制条件和业务数据特征的限制条件的规则。
例14:选择规则(13):
禁止使用UP方案发起低于预设数据包大小门限的业务、或者低于累积数据量门限的业务、或者低于预设流量门限的业务(指禁止使用UP方式发送小数据/小流量业务,因为UP方案适合用于传输大数据/大流量)
该规则也将业务数据特征的限制条件与接入方法的限制条件进行了结合,不同的是接入方法的限制条件针对UP方式,因而其对应的业务数据特征的限制条件和规则(13)是不同的,本例强调UP方案不能用来传输小数据包或者低流量的业务。
eNB发送上述规则时,可以选择其中一条,也可以选择多条,选择多条规则时应当保证规则之间没有相互冲突,也没有相互重复的部分。
示例3:
本示例用来说明结合额外的限制参数后可以形成的更灵活的接入限制方式。
在示例2的接入限制规则的基础上,eNB还可以额外发送其他限制参数来和接入限制规则进行配合,形成新的更加灵活的接入限制规则。
所述额外的限制参数包括:
时间参数、比例参数、数据模型参数:
-时间参数:增加对应的wait timer,以规定所述接入限制规则生效 的时长;
-比例参数:增加概率因子或者比例因子,以规定所述接入限制规则生效的概率或者UE比例;
-数据模型门限:增加数据包大小门限、或者累积数据量门限、或者流量门限、或者连续数据包的数量门限、或者连续数据包的频度/周期门限,以规定所述接入限制规则中包含的业务禁止超过所述数据模型门限、或者禁止低于所述数据模型门限;
上述3种参数可以选择1种参数或者多种参数的组合,与前述的接入限制规则进行结合来形成新的规则。
上述3种参数的具体数值可由eNB配置,并通过广播消息或者寻呼、或者专用信令通知给UE。
例1:将规则(2)“禁止使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫”与所述时间参数结合,可以形成新的规则如下:
在设定时间范围A内禁止使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫。
所述时间范围A可由eNB配置,并通过广播消息或者专用信令通知给UE。
例2:将规则(2)“禁止使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫”与所述比例参数结合,可以形成新的规则如下:
禁止预设比例B的用户数使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫。
所述预设比例B可由eNB配置,并通过广播消息或者专用信令通知给UE。eNB可以通过这种方式禁止比例B的用户数量使用CP方式发起 受限制业务类型的呼叫。
例3:将规则(2)“禁止使用CP方式发起mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫”与所述数据模型门限结合,其中数据模型门限又包含数据包大小门限、或者累积数据量门限、或者流量门限、或者连续数据包的数量门限、或者连续数据包的频度/周期门限,可以选择其中一种或者多种。可以形成新的规则如下:
禁止使用CP方式发起超过数据包大小门限的delayTolerantAccess的呼叫;
禁止使用CP方式发起超过累积数据量门限的mo-signaling的呼叫;
禁止使用CP方式发起超过流量门限的mo-ExceptionData的呼叫;
禁止使用CP方式发起超过连续数据包的频度/周期门限的mo-ExceptionData、或者delayTolerantAccess、或者mo-signaling的呼叫;
禁止使用CP方式发起超过流量门限,或者超过连续数据包的数量门限的mo-ExceptionData的呼叫;
例4:将规则“禁止发送non-IP-data业务”与时间参数、比例参数以及数据模型门限同时结合,形成新规则如下:
在预设时间范围A内,禁止预设比例B的用户数量发送超过流量门限的non-IP-data业务;
示例4:
本示例用来说明本发明所述的接入限制规则和限制参数与现有的LTE接入限制(Access Barring,ACB)以及(Extended Access Barring,EAB)的关系。
现有LTE已经有ACB和EAB机制,其参数均通过***广播消息SIB2发送,本发明所述的接入限制规则和限制参数与ACB或者EAB属于并列关系,有以下2种方法来处理二者的关系:
UE获取ACB参和EAB参数,以及本发明实施例所述的接入限制规则和限制参数后,UE先执行本发明所述的接入限制规则和限制参数的判断,如果UE通过了判断,则UE需要再执行ACB参或者EAB参;
UE获取ACB参和EAB参数,以及本发明实施例所述的接入限制规则和限制参数后,UE先执行ACB或者EAB,如果UE通过了判断,则UE需要再执行本发明所述的接入限制规则和限制参数的判断。

这里的接入限制规则与前述实施例中的一致,故在此就不重复了。
如图5所示,本实施例还提供一种接入控制方法,包括:
步骤S1:eNB向UE发送指示信息;
步骤S2:UE基于所述指示信息,确定当前生效的接入限制规则;
步骤S3:当有接入需求时,查询当前生效的接入限制规则,确定是否允许当前接入需求对应的接入请求的发起;

步骤S5:若不允许接入,屏蔽当前接入需求的响应。
在一些特定情况,所述禁止接入的UE的类型,可以根据不同类型的UE的优先级和/或型号来确定,优先选择接入允许延时大的UE作为禁止接入的UE的类型。
在还有一些特定情况下,所述禁止接入的业务的类型,可以根据业务的优先级、允许延时性及服务质量(Quality of Service,QoS)等,选择优先级低、允许延时大及QoS的要求低的业务作为所述禁止接入的业务类型。
所述禁止使用的接入方式,可以根据当前每一种接入方式用于UE接入时所消耗的资源及繁忙程度,选择当前禁止使用的接入方式。在一些情况下,若当前网络的负载率越高或拥塞程度越高,优先选择接入方式消耗大的接入方式为禁止接入的方式,或使用该方式的UE接入之后消耗的带宽大的接入方式为禁止使用的接入方式,也可以根据对应接入方式发起业务的重要性及可延时性等参数来选择可延时性大的业务及重要性低的业务对应的接入方式为禁止使用的接入方式。
