  • the supported network slice type In order to maximize the flexibility of network side slice deployment, the slice types deployed in different frequency point cells support independent configuration. At present, the cell reselection between the same-frequency cells does not need to consider the limitation of the network slice.
  • the terminal (User Equipment, UE) performing the inter-frequency cell reselection or handover is preferably reselectable or switched. On the inter-frequency cell supporting its service, otherwise the UE has the possibility of frequently performing inter-frequency cell reselection or handover. Under extreme conditions, there is even a possibility that the connected state UE service is interrupted.
  • the base station knows the slice information that the UE is currently allowed to access, it can configure a dedicated cell reselection priority for the UE based on the information.
  • the cell reselection priority based on the base station configuration is reselected, and the target cell selected by the UE is also supported to support the slice currently allowed by the UE.
  • the UE initiates access in the cell, it carries the slice information that is desired to be accessed, so that the base station can access the UE to its desired slice and provide corresponding services.
  • the slice of the radio side/base station is always available. Therefore, as long as the UE performs cell reselection based on the reselection priority of the network configuration, it does not camp on the base station that does not support the UE slice.

Description

一种切片管理方法、基站及终端
相关申请的交叉引用
本申请主张在2017年11月16日在中国提交的中国专利申请号No.201711139048.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域，特别涉及一种切片管理方法、基站及终端。
背景技术
第五代移动通信新空口(5th-Generation New RAT，5G NR)***中引入了切片的新概念，不同的切片类型对应着不同的业务类型，运营商可以根据自身的需求在网络侧灵活配置其所支持的网络切片类型。为了最大限度提高网络侧切片部署的灵活性，不同频点小区部署的切片类型支持独立配置。目前，同频小区之间的小区重选不需要考虑网络切片的限制，在网络部署切片的背景下，进行异频小区重选或者切换的终端(User Equipment，UE)最好能够重选或者切换到支持其业务的异频小区上，否则UE存在频繁进行异频小区重选或切换的可能性，在极端条件下，甚至存在连接态UE服务中断的可能性。
在网络部署切片的场景下，不同频点可以部署不同的切片，同一个频点上支持的切片是相同的。也就是说，切片和频点之间有一定的对应关系。因此，当基站知道UE当前所允许接入的切片信息，就可以基于该信息为UE配置专用的小区重选优先级。当UE进入空闲态时，基于基站配置的小区重选优先级进行重选，可以保证UE选择到的目标小区也是支持UE当前所允许接入的切片的。当UE在该小区发起接入时，会携带希望接入的切片信息，这样基站就可以将UE接入其期望的切片，并提供相应的服务。
但相关技术中，切片的使用方法中有一个前提条件，就是认为无线侧/基站的切片总是可用的。因此，只要UE基于网络配置的重选优先级进行小区重选，就不会驻留到不支持该UE切片的基站。从而后续UE总可以发起接入 过程，接入其期望的切片以接受服务。但是实际中，无线侧/基站的切片并不是总为可用的，可能因为软硬件升级或者网络异常，导致某些切片临时不可用。
由于网络切片还存在临时不可用的情况，即使UE基于网络配置的专用小区重选优先级信息进行同频和异频的小区重选，仍然可能存在某个基站支持的切片临时不可用的情况，导致UE在该基站接入其期望切片时失败，而UE无法得知其期望的切片临时不可用，会频繁发起不必要的接入，增加***开销。

在本公开的一些实施例中，参照图1所示，提供了一种切片管理方法，包括：
步骤101，接收终端发送的接入请求，所述接入请求中包含所述终端希望接入的目标切片。
这里，网络侧接收终端发送的接入请求，终端UE发起接入请求时，会携带希望接入的目标切片信息，这样网络侧就可以将UE接入其希望的目标切片，并提供相应的服务。
步骤102，当确定无法提供所述目标切片的服务时，向所述终端发送无法提供所述目标切片的服务的通知消息。
这里，网络侧的切片并不是总为可用的，可能因为软硬件升级或者网络异常，导致某些切片临时不可用。当网络侧确定无法提供目标切片的服务时，通过向UE发送无法提供目标切片的服务的通知消息，使UE可尽快接入其他切片，且避免了频繁发起不必要的接入。
本公开实施例的切片管理方法，网络侧确定无法提供目标切片的服务时，向终端发送无法提供目标切片的服务的通知消息，从而终端能够获知其希望接入的目标切片临时不可用，使终端可尽快接入其他切片，提升了用户体验，且避免了频繁发起不必要的接入，降低了***开销。
可选地，上述步骤102包括：
步骤1021，当确定无法提供所述目标切片的服务时，释放所述终端的无线资源，并向所述终端发送释放消息，所述释放消息中携带有释放原因，所述释放原因为所述目标切片临时不可用或者无法支持所述目标切片。
这里，UE接入网络侧时通知网络侧其希望接入的目标切片，网络侧判断无法提供目标切片的服务时，释放UE的无线资源，同时通知UE释放原因是目标切片临时不可用或者无法支持目标切片，从而UE能够获知目标切片临时不可用或者无法支持目标切片，使UE可尽快接入其他切片，且避免了频繁发起不必要的接入。此时通知消息具体为释放消息。
其中，释放消息如可以是无线资源控制(Radio Resource Control，RRC)连接释放消息。
可选地，上述步骤102包括：
步骤1022，当确定无法提供所述目标切片的服务时，拒绝所述终端的接入请求，并向所述终端发送拒绝消息，所述拒绝消息中携带有拒绝原因，所述拒绝原因为所述目标切片临时不可用或者无法支持所述目标切片。
这里，UE接入网络侧时通知网络侧其希望接入的目标切片，网络侧判断无法提供目标切片的服务时，拒绝UE的接入，同时通知UE拒绝原因是目标切片临时不可用或者无法支持目标切片，从而UE能够获知目标切片临时不可用或者无法支持目标切片，使UE可尽快接入其他切片，且避免了频繁发起不必要的接入。此时通知消息具体为拒绝消息。
其中，拒绝消息如可以是RRC连接拒绝消息。
可选地，当确定无法提供所述目标切片的服务时，还包括：
步骤103，向终端发送切片临时不可用的定时器，使得所述终端根据所述定时器进行小区重选。
这里，当网络侧确定无法提供目标切片的服务时，向UE发送无法提供目标切片的服务的通知消息的同时，还可以发送切片临时不可用的定时器，使得UE可根据定时器进行小区重选。
其中，当通知消息具体为释放消息时，可在释放消息中携带释放原因和/或切片临时不可用的定时器。当通知消息具体为拒绝消息时，可在拒绝消息中携带拒绝原因和/或切片临时不可用的定时器。
当释放消息中仅携带有释放原因或拒绝消息中仅携带有拒绝原因时，UE收到释放消息或拒绝消息后，可将当前频点作为最低优先级进行小区重选，这样UE就不会选择临时不可用的目标切片，而尽快接入其他切片，提升了用户体验，避免了不必要的接入。
当释放消息中同时携带释放原因和切片临时不可用的定时器，或拒绝消息中同时携带拒绝原因和切片临时不可用的定时器时，UE收到释放消息或拒绝消息后，可在定时器超时之前，将当前频点的优先级修改为最低优先级后进行小区重选，这样UE就不会选择临时不可用的目标切片，而尽快接入其他切片，提升了用户体验，避免了不必要的接入；在定时器超时之后，UE可将当前频点的优先级恢复至修改前的优先级后进行小区重选，保证UE能够 正常接入目标切片。
其中，本公开实施例中对UE基于频点的优先级进行小区重选的具体执行过程不作限定，可采用任意一种公知方式。
进一步的，向终端发送切片临时不可用的定时器之后，还包括：
步骤104，向终端发送为所述终端配置的频点优先级信息，使得所述终端根据所述定时器以及所述频点优先级信息进行小区重选。
这里，当网络侧确定无法提供目标切片的服务时，向UE发送无法提供目标切片的服务的通知消息的同时，还可以发送切片临时不可用的定时器以及为UE配置的频点优先级信息，使得UE可根据定时器以及频点优先级信息进行小区重选。
其中，上述步骤104也可在步骤103之前执行，或者与步骤103同时执行。即网络侧可先向终端发送切片临时不可用的定时器，再向终端发送为终端配置的频点优先级信息，或者先向终端发送为终端配置的频点优先级信息，再向终端发送切片临时不可用的定时器，或者两者同时发送。
其中，如前文所述，当通知消息具体为释放消息时，可在释放消息中携带释放原因和/或切片临时不可用的定时器，并发送频点优先级信息。当通知消息具体为拒绝消息时，可在拒绝消息中携带拒绝原因和/或切片临时不可用的定时器，并发送频点优先级信息。
当释放消息中同时携带释放原因和切片临时不可用的定时器，或拒绝消息中同时携带拒绝原因和切片临时不可用的定时器时，UE收到释放消息或拒绝消息后，可在定时器超时之前，使用网络侧配置的频点优先级信息进行小区重选，优选的频点优先级信息中目标切片对应的频点不是最高优先级，这样UE就不会选择临时不可用的目标切片，而尽快接入其他切片，提升了用户体验，避免了不必要的接入；在定时器超时之后，UE可将当前频点的优先级修改为最高优先级后进行小区重选，或者使用网络配置的频点优先级信息进行小区重选，保证UE能够正常接入目标切片。
综上，作为一种可选地实现方式，UE接入网络侧时通知网络侧其希望接入的目标切片，网络侧判断无法提供目标切片的服务时，可通过RRC连接释放消息释放UE，并在释放消息中携带释放原因为目标切片临时不可用或者无 法支持目标切片。进一步的，网络侧也可以在该释放消息中同时携带切片临时不可用的定时器。如果释放消息中仅有释放原因，没有切片临时不可用的定时器，那么UE收到该释放消息后，可将当前频点作为最低优先级进行小区重选。如果释放消息中包含释放原因，也包含切片临时不可用的定时器，有两种处理方式：
1)UE收到该释放消息后，在定时器超时之前，将当前频点的优先级修改为最低优先级后进行小区重选，在定时器超时之后，将当前频点的优先级恢复至修改前的优先级后进行小区重选。
2)UE收到该释放消息后，在定时器超时之前，根据网络侧配置的频点优先级信息进行小区重选，在定时器超时之后将当前频点的优先级修改为最高优先级后进行小区重选，或者根据网络配置的频点优先级信息进行小区重选。
作为另一种可选地实现方式，UE接入网络侧时通知网络侧其希望接入的目标切片，网络侧判断无法提供目标切片的服务时，可通过RRC连接拒绝消息拒绝UE，并在拒绝消息中携带拒绝原因为目标切片临时不可用或者无法支持目标切片。进一步的，网络侧也可以在该拒绝消息中同时携带切片临时不可用的定时器。如果拒绝消息中仅有拒绝原因，没有切片临时不可用的定时器，那么UE收到该拒绝消息后，可将当前频点作为最低优先级进行小区重选。如果拒绝消息中包含拒绝原因，也包含切片临时不可用的定时器，有两种处理方式：
1)UE收到该拒绝消息后，在定时器超时之前，将当前频点的优先级修改为最低优先级后进行小区重选，在定时器超时之后，将当前频点的优先级恢复至修改前的优先级后进行小区重选。
2)UE收到该拒绝消息后，在定时器超时之前，根据网络侧配置的频点优先级信息进行小区重选，在定时器超时之后将当前频点的优先级修改为最高优先级后进行小区重选，或者根据网络配置的频点优先级信息进行小区重选。
