实现业务初始化重定向、切换的方法和基站

本申请主张在2017年6月28日在中国提交的中国专利申请No.201710506177.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及业务初始化技术，特别是指一种实现业务初始化重定向、切换的方法和基站。
背景技术
当前通信网络中存在许多高干扰场景，例如大气波导干扰，高负荷场景，以及弱覆盖场景。在这些高干扰场景下，可能会出现基于IMS的语音业务(VoLTE，Voice over LTE)起呼失败的现象。
相关的解决起呼失败的技术包括：VoLTE业务起呼时振铃之前的切换(bSRVCC，Single Radio Voice Call Continuity(SRVCC)before ringing)技术，在VoLTE起呼过程中，将本次通话采用增强的单一无线语音呼叫连续性(eSRVCC，Enhanced Single Radio Voice Call Continuity)移至2G起呼；在VoLTE起呼过程中进行LTE***内切换，通过传统切换流程将用户切换至相邻同频或异频LTE小区。
bSRVCC技术无法解决被叫起呼失败问题，且无法解决VoLTE业务承载建立完成前的切换问题，且切换时延比LTE***内切换时延长。这是因为：在进行eSRVCC切换时，终端UE会对本小区信号和异***2G频点进行测量，在本小区信号低于门限而2G频点信号高于门限时才会切换至2G频点。
LTE***内切换技术，存在切换流程与VoLTE业务承载建立流程冲突的问题。这是因为：VoLTE起呼时，需要先建立业务承载，随后才能进行通话；在进行LTE***内同频或异频切换前，终端UE会对同频频点或异频频点提前进行测量，在满足切换门限的条件下才会发生LTE***内切换。在遇到这种情况时，优先建立VoLTE业务承载，然后再进行切换，因此存在建立承载 失败或承载丢失的风险，换言之，承载建立和***内切换是两个不同的流程，两者是互相独立的，所以有可能同时发生，这样这两个流程就会产生冲突，基站需要判断到底先处理哪个流程。

在终端初始化一个业务时，检测终端随机接入过程中上发的随机接入信令中的连接建立原因字段；
若检测到所述连接建立原因字段是主叫终端发起初始化一个业务，则检测当前的预设条件，若所述预设条件超过阈值，则触发所述重定向流程。

在一个应用场景中，终端UE初始化一个业务具体是指：终端UE进行语音业务起呼过程，则基站在终端随机接入过程中，将终端UE重定向至其他 ***或频点或小区，终端需在目标小区重新发起该语音业务，这包括：
在终端发起VoLTE语音起呼过程之后，基站检测终端随机接入过程中上发的MSG3消息-如RRC连接建立请求RRCConnectionRequest中的RRC连接建立原因字段，RRC连接建立原因字段至少包括：紧急呼叫、高优先级接入、被叫接入、主叫信令传输、主叫数据传输和主叫发起语音呼叫等；
若基站检测到MSG3消息中的原因字段为“主叫发起语音呼叫”，例如mo-VoiceCall，则检测当前预设条件，预设条件包括：无线环境质量、干扰情况、负荷情况和业务质量等；
若预设条件超过了阈值，则触发重定向流程。
其中，基站检测当前预设条件包括：检测基站自身的预设条件，也可以通过与其他相邻基站进行信息交互，检测相邻基站的预设条件；设条件包括：

干扰，如SINR、上行底噪抬升(IoT)等；
负荷情况，如PRB资源占用率、小区用户数、话务量等；

在一个可选实施例中，在重定向流程中，将终端重定向至其他目标***、目标频点或者目标小区包括：
在终端随机接入过程中，下发给终端的随机接入信令中携带有其他目标***、目标频点或者目标小区，随机接入信令指示终端需要尝试连接到其他目标***、目标频点或者目标小区；
在终端随机接入过程中，下发给终端的随机接入信令的原因值中携带重定向原因，或者原因值中携带其他目标***、目标频点或者目标小区，或者原因值中携带这两个部分，指示终端需要尝试连接到其他目标***、目标频点或者目标小区；
基站在随机接入过程中接收到上发的随机接入信令后，或者在随机接入完成后业务承载建立前，下发连接释放消息给终端，所述连接释放消息的原因值中携带重定向原因，或者携带其他目标***、目标频点或者目标小区，或者携带这两个部分，指示终端需要尝试连接到其他目标***、目标频点或者目标小区；
在终端随机接入过程中，下发给终端的随机接入信令中，或者同时携带的测量控制消息中，指示终端对测量控制消息中所携带的频点进行测量得到测量信息；若终端上报的测量信息满足预设条件，则向终端发送重定向指示，重定向指示中携带重定向其他目标***、目标频点或者目标小区，指示终端需要尝试连接到其他目标***、目标频点或者目标小区；
选择在下发随机接入信令消息给终端前，检测终端发送给基站的随机接入信令消息的上行发射功率，选择性的将终端重定向至合适的他目标***、目标频点或者目标小区。
在一个应用场景中，重定向流程的实现是多种多样的，这包括：
方式一，如图2、图3所示，在终端UE发起VoLTE语音起呼过程之后，基站检测UE随机接入过程中上发的MSG3消息中的RRC连接建立原因字段；
若基站检测到MSG3消息中的原因字段为“主叫发起语音呼叫”，例如mo-VoiceCall，则检测本小区上行干扰是否超过了阈值；
若超过了阈值，基站可在终端UE随机接入过程中下发给终端UE的MSG4消息-如RRC连接建立RRCConnectionSetup中，携带重定向目标***或频点或小区信息-如redirectedCarrierInfo，该信息值可以为显式(如2.6GHz)，也可为隐式(如f1、f2)，指示终端UE下一步需要尝试连接到目标***或频点或小区；
终端UE在收到RRCConnectionSetup后，需立即在目标小区重新发起该业务。
方式二，如图4、图5所示，基站检测到终端UE随机接入MSG3消息携带的原因值为mo-VoiceCall；
检测本小区上行干扰是否超过了阈值；
若超过了阈值，基站可在终端UE随机接入过程中下发给终端UE的MSG4消息-如RRC连接拒绝RRCConnectionReject的原因值中携带重定向原因-如rejectCause：redirection，或重定向目标***或频点或小区信息-如redirectedCarrierInfo，或上述两部分均包含，该信息值可以为显式(如2.6GHz)，也可为隐式(如f1、f2)，指示UE下一步需要尝试连接到目标***或频点或小区；
终端UE在收到MSG4后，需立即在目标小区重新发起该业务。
方式三，如图6、图7所示，基站检测到UE随机接入MSG3消息携带的原因值为mo-VoiceCall；
检测本小区上行干扰是否超过了阈值；
若超过了阈值，基站可在随机接入过程中接收到MSG3消息后，也可以在随机接入完成后业务承载建立前，下发RRC连接释放消息-如RRCConnectionRelease给UE，消息的原因值中携带重定向原因-如releaseCause：redirection，或重定向目标***或频点或小区信息-如redirectedCarrierInfo，或上述两部分均包含，该信息值可以为显式(如2.6GHz)，也可为隐式(如f1、f2)，指示终端UE下一步需要尝试连接到目标***或频点或小区；
终端UE在收到RRCConnectionRelease后，需立即在目标小区重新发起该业务。
同理，如图8所示，基站在接收到MSG5之后，基站向终端UE发送RRCConnectionRelease消息方式，这一过程中包括：
基站检测到UE QCI5承载数据包内容为INVITE消息，若判定相邻小区上行干扰小于本小区,基站立即下发重定向指示(如RRCConnectionRelease)，并携带重定向载波信息(如redirectedCarrierInfo)，与核心网更新信令面与媒体面的路径信息,UE在收到重定向命令后，需立即在目标小区重新发起该业务。
方式四，可在终端UE随机接入过程中基站下发给终端UE的MSG4消息-即RRC连接建立RRCConnectionSetup中也可以同时携带测量控制消息-如measConfig，指示终端UE对测量控制消息中所携带的频点进行测量；若UE上报的测量信息满足预设条件，则向终端UE发送重定向指示-如RRCConnectionRelease，该消息中携带重定向目标***或频点或小区信息-如redirectedCarrierInfo，该信息值可以为显式(如2.6GHz)，也可为隐式(如f1、f2)，指示UE下一步需要尝试连接到目标***或频点或小区；
方式五，基站可选择在下发上述消息给终端UE前，检测终端UE发送给基站的MSG3消息的上行发射功率，有选择性的将终端UE重定向至合适的 小区；具体流程可包括：
若上述上行发射功率超过阈值，则可初步判断该终端UE处于小区边缘或高干扰场景，并选择将该终端UE重定向至相邻同***异频或异***小区；若上述上行发射功率未超过阈值，则可初步判断该终端UE处于小区中心或低干扰场景，可根据实际需求，将该终端UE重定向至与本小区或本频点重叠覆盖的同***异频或异***小区；基站也可不选择检测终端UE上行发射功率，直接为终端UE指定重定向的目标***或频点或小区。
在一个可选实施例中，终端UE在收到重定向命令后，需在目标小区重新发起初始化业务，不能够主动断开连接。
重定向流程不仅仅可以发生在随机接入过程中，还可以发生在随机接入过程之后。如图9所示，在一个可选实施例中，当终端UE初始化一个业务时，检测到终端执行的随机接入过程，触发重定向流程包括：
在完成了随机接入，以及建立了对应的承载之后，基站对承载数据包进行深度包检测；
若在承载数据包中检测出第一类消息，则基站检测当前的预设条件，若预设条件超过了阈值，则触发重定向流程。第一类消息具体可以是主叫终端的邀请(INVITE)消息。
在一个应用场景中，针对VoLTE业务-即语音呼叫业务类型，在随机接入、QCI9与QCI5建立完成之后，基站对QCI5数据包进行深度包检测，该数据包可能为邀请(INVITE)、PRACK、UPDATE等；
若检测出INVITE消息，则基站检测当前预设条件，如无线环境质量、干扰情况、负荷情况和业务质量等，若预设条件超过阈值，则触发重定向流程；
上述基站检测当前预设条件，可以为检测自身预设条件，也可以通过与其他相邻基站进行信息交互，检测相邻基站预设条件。
QCI9指传输数据业务的默认承载，QCI5指SIP信令的默认承载。
在实现业务初始化重定向、业务初始化切换的过程中，需要对基站与终端之间涉及的参数进行检测、传输，其中，QoS Class Identifier是一个标度值，用于衡量特定的提供给服务数据流(SDF)的包转发行为(如丢包率，包延迟预 算)，它同时应用于GBR和Non-GBR承载，用于指定访问节点内定义的控制承载级分组转发方式-如调度权重、接纳门限、队列管理门限、链路层协议配置等，这些都由运营商预先配置到接入网节点中。
