小区拥塞的处理方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2019年12月23日在中国提交的中国专利申请号No.201911339778.4的优先权，其全部内容通过引用包含于此。
技术领域
本发明涉及通信技术领域，尤其是指一种小区拥塞的处理方法、终端及网络侧设备。
背景技术
现网中，当长期演进(Long Term Evolution，LTE)的某个小区业务量大，终端驻留此小区会很容易出现拥塞，导致终端不能正常进行数据业务，对于用户体验具有明显影响。
连接态下终端测量服务小区与邻区的信号强度，当满足网络配置的切换事件后，进行测量上报，网络下发切换指令切换到新的小区。空闲态下终端利用重选优化级，参考信号接收功率(Reference Signal Receiving Power，RSRP)等决定小区重选。但存在如下情况，有一个小区信号较好，但驻留用户数多，业务量较大，若再次切换到此小区，会影响正常的数据业务。
另外，LTE中定义的一些其他拥塞避免机制，大多为半静态的机制。基站无法根据调度状态实时更新。由于基站的调度行为本身，既受到空口传播环境的影响，也受到上下行数据包到达的影响，尤其是下行数据包的到达，和核心网传播环境的拥塞程度有关。因此，在基站引入半静态的调度限制，有可能会影响调度效率，对于网络容量有负效果。
载波聚合(Carrier Aggregation，CA)或双连接(Dual-Connectivity，DC)是解决拥塞的一种方法，但对终端的能力要求相对更高。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的小区拥塞的处理方法、终端及网络侧设备可以应用于无线通信系统中。该无线通信系统可以为采用5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。参考图1，为本发明实施例提供的一种无线通 信系统的架构示意图。如图1所示，该无线通信系统可以包括：网络侧设备10和终端(终端也可称为用户侧设备)，例如终端记做UE11，UE11可以与网络侧设备10连接。在实际应用中上述各个设备之间的连接可以为无线连接，为了方便直观地表示各个设备之间的连接关系，图1中采用实线示意。
需要说明的是，上述通信系统可以包括多个UE，网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本发明实施例提供的网络侧设备10可以为基站，该基站可以为通常所用的基站，也可以为演进型基站(evolved node base station，eNB)，还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)或发送和接收点(transmission and reception point，TRP))或者小区cell等设备。
本发明实施例提供的终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本、可穿戴式设备(Wearable Device)、车载设备或者个人数字助理(Personal Digital Assistant，PDA)等。需要说明的是，在本发明实施例中并不限定终端的具体类型。本发明实施例中以LTE以及NR系统为例，然不限于此系统，本发明提供的技术方案可以应用于存在相同问题的其他系统。
如图2所示，本发明实施例提供一种小区拥塞的处理方法，应用于终端，包括：
步骤201，接收网络侧设备发送的拥塞指示信息，所述拥塞指示信息用于指示第一小区存在拥塞。
其中，所述第一小区为所述终端驻留的小区，或者，第一小区为终端的服务小区。
步骤202，根据所述拥塞指示信息，所述终端接入第二小区。
本步骤中，第二小区和第一小区为不同的小区。可选的，第二小区为第一小区的邻小区。
可选的，步骤201包括：
接收N比特信息，N为大于或者等于1的整数；
其中，在所述N比特信息为第一值的情况下，所述N比特信息用于指示 第一小区存在拥塞；在所述N比特信息为第二值的情况下，所述N比特信息用于指示第一小区不存在拥塞。
例如，一个小区的拥塞指示可以用1比特信息指示，例如，“1”表示对应的小区存在拥塞，“0”表示对应的小区不存在拥塞；再例如，“1”表示对应的小区存在拥塞，“0”或不下发这1比特信息表示对应的小区不存在拥塞。
本发明实施例中，通过网络侧设备发送的拥塞指示信息指示第一小区存在拥塞，终端根据该拥塞指示信息接入到新的小区，能够避免终端接入到拥塞小区，提升用户数据体验。
需要说明的是，拥塞指示信息中还可以包含一个小区存在拥塞指示的持续时长T，则该持续时长T内终端会认为该小区一直拥塞。增加持续时长T的指示能够减少信令的交互；例如，该持续时长T内网络侧无需再次针对该小区是否存在拥塞进行指示。
作为一个可选实施例，步骤201包括：
接收网络侧设备发送的下行控制信息DCI或媒体接入控制层控制单元MAC CE或无线资源控制RRC信令，所述DCI或MAC CE或RRC信令携带所述拥塞指示信息。
MAC CE为数据包的MAC头中包含的控制字段。由于MAC层一般为网络的调度控制层，因此，MAC CE一般也保护调度相关的信息。在NR中，MAC CE可以用于指示逻辑信道的推荐比特率，各种资源集合以及准共址QCL关系的激活，非连续接收DRX命令等等。
物理下行控制信道PDCCH传输的是与物理上下行共享信道(物理上行共享信道PUSCH、物理下行共享信道PDSCH)相关的控制信息，即下行控制信息(Downlink Control Information，DCI)，这些DCI信息包含了诸如资源块RB资源分配信息、调制方式MCS、混合自动重传请求应答HARQ-ACK等等若干相关内容。终端只有正确的解码到了DCI信息，才能正确的处理PDSCH数据或PUSCH数据。
本发明实施例中，终端根据拥塞指示信息接入第二小区主要包括两种方式，方式一为：终端转入空闲态，并通过小区重选驻留到第二小区；方式二为：终端直接通过小区切换驻留到第二小区。
针对方式一，即步骤202包括：
根据所述拥塞指示信息，所述终端进入空闲态；例如，在浏览网络、听歌等非链接性数据业务时，终端通常会不断从空闲态到连接态，再到空闲态。
所述终端按照预设规则进行小区重选并驻留到第二小区；其中，所述预设规则包括下述至少一项；
降低第一小区对应的频点优先级；
降低第一小区对应的频点的偏移值；
禁止接入存在拥塞的小区。
可选的，终端重回空闲态不仅需要参考拥塞指示信息，还需要参考终端自身的业务需求是否得到满足。例如，在一个预设的时间窗内，终端根据高层信息确定自身的业务需求没有得到满足，且网络通过拥塞指示信息指示第一小区存在拥塞，则终端回到空闲态，并重选到第二小区。
针对方式二，即步骤202包括：
根据所述拥塞指示信息，上报拥塞测量事件对应的测量报告；
接收网络侧设备基于所述测量报告发送的第一切换信令；
根据所述第一切换信令，切换至所述第二小区。
可选的，所述根据所述拥塞指示信息，上报拥塞测量事件对应的测量报告，包括：
在所述终端的业务需求没有得到满足，且所述拥塞指示信息指示第一小区存在拥塞的情况下，上报拥塞测量事件对应的测量报告。
本发明实施例中，拥塞测量事件对应的测量报告的上报条件，不仅需要参考拥塞指示信息，还需要参考终端自身的业务需求是否得到满足。
作为一个可选实施例，所述在所述终端的业务需求没有得到满足，且所述拥塞指示信息指示第一小区存在拥塞的情况下，上报拥塞测量事件对应的测量报告，包括：
在预设时间长度的时间窗内，若所述终端的业务需求没有得到满足，且所述拥塞指示信息指示第一小区存在拥塞，上报拥塞测量事件对应的测量报告。
例如，在一个预设的时间窗内，终端根据高层信息确定自身的业务需求 没有得到满足，且网络通过拥塞指示信息指示第一小区存在拥塞，则终端上报针对拥塞测量事件对应的测量报告，并基于网络的第一切换信令，切换至第二小区。
可选的，方式二中，所述接收网络侧设备发送的拥塞指示信息之前，所述方法还包括：
接收网络侧设备为所述终端配置的所述拥塞测量事件。
该拥塞测量事件的触发条件中，邻小区的门限相较于普通测量事件中邻小区的门限更低，使得邻小区的信号质量更容易满足触发条件；优选的，拥塞测量事件的触发条件中邻小区的门限小于一预设值。
承接上例，本发明的上述实施例中步骤202之后，所述方法还包括：
所述终端进行邻区测量，在满足切换上报事件的条件时上报邻区测量报告；
其中，若所述终端测量的邻区中至少一个小区存在拥塞，所述邻区测量报告中携带存在拥塞的小区的拥塞指示信息。
本发明实施例中，终端接入第二小区之后，测量到的邻区满足切换条件且某一个邻区存在拥塞，则进行测量上报时填加拥塞指示信息，以告知当前服务小区的基站，某一邻区存在拥塞。
例如，终端驻留在第二小区，则终端上报邻区测量报告时，若邻区测量报告中包含第一小区的测量信息，且第一小区存在拥塞，则邻区测量报告中携带第一小区的拥塞指示信息。
需要说明的是，本发明实施例不限于两小区场景，若终端在多小区间切换，则终端可以保存多个小区的拥塞状态，在邻区测量上报时，也会进行拥塞指示信息的上报。
进一步的，终端上报邻区测量报告之后，网络根据当前已获取的小区的信息判断是否下发第二切换指令；若网络下发第二切换指令，且第二切换指令指示终端切换至第一小区，则之后如果第一小区仍处于拥塞状态，终端根据之前的流程回到第二小区，则终端再进行邻区测量上报。
综上，本发明的上述实施例提供的小区拥塞的处理方法中，通过网络侧设备发送的拥塞指示信息指示第一小区存在拥塞，若终端处于空闲态且服务 小区存在拥塞，终端可以通过降低服务小区对应的频点优化级或者偏移值的方式重选到第二小区；若终端处于连接态且服务小区存在拥塞，终端上报针对拥塞测量事件对应的测量报告，并基于网络的第一切换信令，切换至第二小区；从而能够避免终端接入到拥塞小区，提升用户数据体验。
如图3所示，本发明实施例还提供一种小区拥塞的处理方法，应用于网络侧设备，包括：
步骤301，向终端发送拥塞指示信息，所述拥塞指示信息用于指示第一小区存在拥塞。
其中，所述第一小区为所述终端驻留的小区，或者，第一小区为终端的服务小区。
需要说明的是，拥塞指示信息中还可以包含一个小区存在拥塞指示的持续时长T，则该持续时长T内终端会认为该小区一直拥塞。增加持续时长T的指示能够减少信令的交互；例如，该持续时长T内网络侧无需再次针对该小区是否存在拥塞进行指示。
作为一个可选实施例，步骤301包括：
向终端发送下行控制信息DCI或媒体接入控制层控制单元MAC CE或无线资源控制RRC信令，所述DCI或MAC CE或RRC信令携带所述拥塞指示信息。
MAC CE为数据包的MAC头中包含的控制字段。由于MAC层一般为网络的调度控制层，因此，MAC CE一般也保护调度相关的信息。在NR中，MAC CE可以用于指示逻辑信道的推荐比特率，各种资源集合以及准共址QCL关系的激活，非连续接收DRX命令等等。
物理下行控制信道PDCCH传输的是与物理上下行共享信道(物理上行共享信道PUSCH、物理下行共享信道PDSCH)相关的控制信息，即下行控制信息(Downlink Control Information，DCI)，这些DCI信息包含了诸如资源块RB资源分配信息、调制方式MCS、混合自动重传请求应答HARQ-ACK等等若干相关内容。终端只有正确的解码到了DCI信息，才能正确的处理PDSCH数据或PUSCH数据。
作为一个可选实施例，步骤301包括：
在满足下述至少一项条件的情况下，向终端发送拥塞指示信息；所述条件包括：
网络侧设备对其他终端的调度会减少给当前终端调度的时频域资源；
被调度的所述终端的数据包在所述网络侧设备的缓存区内驻留的时长大于第一预设值；
第一小区服务的用户数大于第二预设值；
需要提供给所述第一小区的传输带宽大于第三预设值。
可选的，在满足上述至少一项条件的情况下，发送N比特信息，且N比特信息为第一值；否则，发送N比特指示信息，且N比特指示信息为第二值；或者，不发送N比特指示信息；其中，N为大于或者等于1的整数。
例如，一个小区的拥塞指示可以用1比特信息指示；网络侧设备调度器需要调度其它终端，且对其它终端的调度会减少给当前终端调度的时频域资源，则网络下发1比特并置1，来指示存在拥塞。如果网络侧设备调度器不会因为调度其它终端，减少给当前终端调度的时频域资源，则网络不下发这1比特的指示信息，或将这1比特信息位置0，即指示对当前终端而言不存在拥塞。
再例如，网络侧设备调度器发现被调度的数据包到达网络侧设备缓存区后，在缓存区内驻留的时长大于第一预设值，则下发该比特并置1。即网络侧设备因为种种原因无法迅速调度缓存区的数据，因而造成延迟。
又例如，网络侧设备判断小区拥塞还可根据当前的小区服务的用户数，需要提供的传输带宽，网络侧设备侧数据累积情况等因素，在此不一一枚举。
作为一个可选实施例，步骤302之后，所述方法还包括：
接收所述终端上报的拥塞测量事件对应的测量报告；

进一步的，向终端发送拥塞指示信息之前，所述方法还包括：
为所述终端配置所述拥塞测量事件。
该拥塞测量事件的触发条件中，邻小区的门限相较于普通测量事件中邻小区的门限更低，使得邻小区的信号质量更容易满足触发条件；优选的，拥 塞测量事件的触发条件中邻小区的门限小于一预设值。
综上，本发明的上述实施例提供的小区拥塞的处理方法中，通过网络侧设备发送的拥塞指示信息指示第一小区存在拥塞，终端根据该拥塞指示信息接入到新的小区，从而能够避免终端接入到拥塞小区，提升用户数据体验。
为了更清楚的描述本发明实施例提供的小区拥塞的处理方法，下面结合两个附图及两个示例进行详细描述。
示例一，如图4所示的小区拥塞的处理方法包括：
步骤401，终端驻留在小区A进入连接态；
步骤402，网络侧设备判断小区A是否拥塞。
步骤403，如果小区A存在拥塞，通过DCI或MAC CE或RRC信令向终端反馈小区A的拥塞状态，终端保存此拥塞状态，持续时长为T。在时间T内，终端认为小区A一直拥塞。
步骤404，终端回到空闲态，终端查询到当前小区拥塞后，终端利用降低小区A重选时对应的频点优先级或偏移值或禁掉拥塞小区的方式重选到新的小区B。
步骤405，终端在小区B进行连接态，并进行邻区测量；
步骤406，在进行邻区测量中发现小区A满足切换上报事件，并同时查询到小区A存在拥塞，则在进行测量上报时，需要将拥塞指示包含在邻区测量报告中。之后，终端再经过相同流程进入小区B后，可以不再进行测量上报。
步骤407，由网络侧设备根据当前已获取的小区判断是否下发切换指令。若网络下发了切换指令，终端在经过相同流程回到小区B后，不再进行测量上报。
示例二，如图5所示的小区拥塞的处理方法包括：
步骤501，终端驻留在小区A进入连接态；
步骤502，网络下发专用于拥塞的拥塞测量事件。终端满足拥塞测量事件的条件时，还需要同时判断当前业务需求是否得到满足，即是否存在拥塞，如果存在拥塞才上报测量报告。
步骤503，网络侧设备判断小区A是否拥塞。
步骤504，如果小区A存在拥塞，通过DCI或MAC CE或RRC信令向终端反馈小区A的拥塞状态，终端保存此拥塞状态，持续时长为T。在时间T内，终端认为小区A一直拥塞。
步骤505，当终端判断自身处于拥塞环境后，上报拥塞测量事件对应的测量报告；
步骤506，网络下发切换，终端基于网络下发的切换，切换至新的小区B；
步骤507，终端在小区B进行连接态，并进行邻区测量；
步骤508，在进行邻区测量中发现小区A满足切换上报事件，并同时查询到小区A存在拥塞，则在进行测量上报时，需要将拥塞指示包含在邻区测量报告中。之后，终端再经过相同流程进入小区B后，可以不再进行测量上报。
步骤509，由网络侧设备根据当前已获取的小区判断是否下发切换指令。若网络下发了切换指令，终端在经过相同流程回到小区B后，不再进行测量上报。
