Description

一种被叫接入的方法及装置 技术领域
本申请涉及通信技术领域，例如涉及一种被叫接入的方法及装置。
背景技术
2G、3G移动网络分为电路域和分组域，电路域负责语音和短信通讯，分组域负责数据上网，但对于LTE(Long Term Evolution，长期演进)技术，即4G，这两种域开始融合，电路域业务将加入到分组域上传送，取消了电路域。
4G网络承载语音业务采用LTE电话(VoLTE)方式，即Voice over LTE，它是一种IP数据传输技术，无需2G、3G网，全部业务承载于4G网络上，可实现数据与语音业务在同一网络下的统一。换言之，4G网络下不仅仅提供高速率的数据业务，同时还提供高质量的音视频通话，后者便需要VoLTE技术来实现。
但由于网络建设和完善需要时间，在开始布局4G网络时，受技术和网络覆盖限制，往往不会直接用VoLTE来接管语音业务，而是采用CSFB(Circuit Switch Fallback，电路域回落)方案，让LTE网络下的4G手机在通话时回落到2G/3G网络，为了支持CSFB方案寻呼原因仍然保留了电路域属性。
被叫寻呼虽然区分了电路域和分组域，但是UE(User Equipment，用户设备)接入过程请求消息中接入原因并没有区分，导致演进节点B(eNodeB)无法根据业务优先级进行区分处理，在接入用户较多时无法根据业务优先级接入用户。同时4G网络普及，运营商开始商用VoLTE业务，语音业务开始承载到分组域。分组域业务有多种，不同业务对于接入时延要求是不同的，短信业务、VoLTE业务对于接入时延要求是不同的，如果不细分分组域寻呼原因，eNodeB无法进行区分，在用户接入拥塞时无法根据业务优先级进行处理。
接入时延对于用户体验是非常重要的，对于VoLTE主叫UE接入请求原因中已经增加了原因进行区分，但对于被叫还没有细分，这会对现网用户体验有影响。

S103、发送接入请求消息至基站。
当被叫终端接收到寻呼消息时，向基站发送接入请求消息，其中，该接入请求消息中包括：被叫终端根据寻呼消息中的被叫业务类型信息确定的接入原因信息，以使基站能够根据接入原因，对接入的业务区分处理，如优先接入优先级较高的业务。
本公开实施例中，基站能够通过空中接口，广播支持被叫接入原因指示能力的***消息，而被叫终端接收到该广播消息时，可确定基站支持被叫接入指示能力，以使被叫终端在接收到基站发送的寻呼消息时，根据寻呼消息中的被叫业务类型信息确定接入原因。
本公开实施例中，按照优先级顺序，接入原因可以包括：电路域回落CSFB被叫接入、VoLTE被叫接入和普通数据业务接入等。
其中，在被叫业务类型信息为电路域业务时，确定接入原因为CSFB被叫接入；在被叫业务类型信息为分组域语音业务时，确定接入原因为VoLTE被叫 接入；在被叫业务类型信息为分组域普通数据业务时，确定接入原因为普通数据业务接入。
综上所述，本公开实施例提供的被叫接入的方法，通过对被叫业务进行区分，以使被叫终端能够根据被叫业务类型确定被叫接入原因，从而在接入过程中，使基站能够确定接入原因，根据业务的优先级区别处理。
第二实施例
本公开实施例提供了一种被叫接入的方法，应用于基站。如图2所示，该被叫接入的方法包括：
S201、接收移动管理实体发送的寻呼消息。
其中，当主叫终端进行寻呼时，由移动管理实体(Mobility Management Entity，简称MME)发起被叫寻呼，并对被叫业务进行细分，在下发的寻呼消息携带有被叫业务类型信息。
S202、将接收到的寻呼消息发送至被叫终端。
当基站接收到MME发送的寻呼消息时，通过空中接口发送寻呼消息至被叫终端。其中，该寻呼消息中同样携带有被叫业务类型信息。
S203、接收被叫终端发送的接入请求消息。
其中，被叫终端在接收到基站发送的、携带有被叫业务类型信息的寻呼消息时，能够根据被叫业务类型信息确定接入原因，并将确定的接入原因添加至向基站发送的接入请求消息中。
S204、根据接入请求消息中的接入原因信息，对被叫终端进行接入控制。
当基站接收到被叫终端发送的接入请求消息中时，可根据其中的接入原因，确定接入业务的优先级，然后根据接入业务的优先级，对被叫终端进行接入控制，例如，可优先接入优先级较高的业务，从而提升用户体验。
当接入基站的终端的数量较小时，基站可不必根据被叫接入业务优先级进行处理，而在基站的当前剩余的接纳能力低于预设门限时，为保证时延要求高的业务，可根据接入原因信息确定被叫终端接入的优先级，并根据优先级的高低顺序，优先接入优先级较高的被叫终端。
本公开实施例中，基站能够通过空中接口，广播发送支持被叫接入原因指示能力的***消息，而被叫终端接收到该广播消息时，可确定基站支持被叫接 入指示能力，以使被叫终端在接收到基站发送的寻呼消息时，根据寻呼消息中的被叫业务类型信息确定接入原因。
本公开实施例中，按照优先级顺序，接入原因可以包括：CSFB被叫接入、VoLTE被叫接入和普通数据业务接入等。
综上所述，本公开实施例提供的被叫接入的方法，通过对被叫业务进行区分，以使被叫终端能够根据被叫业务类型确定被叫接入原因，从而在接入过程中，基站能够确定接入原因，根据业务的优先级区别处理。
第三实施例
为了理解本公开第一实施例和第二实施例所述的被叫接入方法，下面以示例加以说明。
本公开实施例中对3GPP TS 36.413协议中Paging message(MME发送至基站的寻呼消息)扩展，消息体中增加可选信元(名称可为CN PS Domain)，被配置为指示分组域被叫业务类型。
本公开实施例中对3GPP TS 36.331协议中Paging message(基站发送至终端的寻呼消息)进行修改，增加可选信元(名称可为Paging-v1410-IE)，对被叫分组域业务细分为语音业务VoiceCall和数据业务Data。
本公开实施例中对3GPP TS 36.331协议中System Information Block Type2中的信息元素进行扩展，增加可选信元(名称可为Voice Service Cause Indication-r14)被配置为指示网络支持被叫VoLTE接入原因指示能力。
本公开实施例中对3GPP TS 36.331协议中RRC接入请求消息(Connection Request Message)中的建立原因(Establishment Cause)扩展，增加支持被叫原因细分，将被叫原因分为：mt-CsCall被叫(CSFB被叫)，mt-PsCall被叫(普通分组域数据被叫)，mt-VoiceCall被叫(VLOTE被叫)等。
如图3所示，实施过程为：
eNodeB(即基站)、MME上电启动，eNodeB创建小区A，支持VoLTE业务，小区A广播消息***信息块类型(System Information Block Type)2信息中信元语音业务原因指示(Voice Service Cause Indication)-r12设置为真(true)，指示UE支持VoLTE业务，Mt业务原因指示(Mt Service Cause Indication)-r14设置为true，通知UE(用户设备)支持被叫接入优化。
假设eNodeB配置最多可以接入303个UE，当前已有300个UE发起主叫业务接入小区A，根据eNodeB配置还能接入3个UE。当UEa、UEb、UEc、……、UEz开机后驻留到小区A。
MME发起对UEa、UEb、UEc、……、UEz的寻呼流程，其中UEa为电路域寻呼，UEb、UEc为VoLTE业务，UEd～UEz为普通数据业务(如短信业务)。
eNodeB下发寻呼消息，通过寻呼(Paging)-v1410-IE指示UE寻呼原因，其中UEa为电路域寻呼，UEb、UEc为VoLTE业务，UEd～UEz为普通数据业务(如短信业务)。
UEa、UEb、UEc接收到寻呼消息，发起RRC接入请求过程请求接入网络，RRC连接请求(Connection Request)消息中建立原因(establishment Cause)携带相关业务接入原因。其中UE1为接入原因mt-CsCall被叫、UE2、UE3接入原因为mt-VoiceCall被叫，UE4～UE30接入原因为mt-PsCall被叫。
eNodeB接收到RRC Connection Request，同时由于待接入UE较多而超出接纳能力，因此根据接入原因进行区分，优先接入业务实时性要求较高UEa、UEb、UEc，对于UEd～UEz拒绝接入。
其中，当同时接入基站的还存在其他业务时，如Emergency(业务紧急呼叫)业务、High PriorityAccess(高优先级接入)业务、mo-VoiceCall(VoLTE主叫)业务、mo-Signalling(信令主叫，仅为信令交互建立，例如位置区更新)业务、Delay TolerantAccess(允许延迟接入)业务、mo-Data(普通数据业务主叫)业务等，则基站可按照如下优先级顺序进行业务接入：Emergency(业务紧急呼叫)业务、High Priority Access(高优先级接入)业务、mt-CsCall(CSFB被叫)业务、mt-VoiceCall(VoLTE被叫)业务、mo-VoiceCall(VoLTE主叫)业务、mt-PsCall(普通分组域数据被叫)业务、mo-Signalling(信令主叫，仅为信令交互建立，例如位置区更新)业务、Delay TolerantAccess(允许延迟接入)业务、mo-Data(普通数据主叫)业务等。当然可以理解是，上述优先级顺序可根据实际需求进行调整，本公开实施例对次不进行限制。
综上所述，本公开实施例提供的技术方案，通过对被叫业务进行区分，以使被叫终端能够根据被叫业务类型确定被叫接入原因，从而在接入过程中，基站能够确定接入原因，根据业务的优先级区别处理。
