Description
本发明涉及LTE移动通讯系统中的数据通信领域,具体涉及一种LTE系统中终端在基站间切换的方法、装置、核心网、系统和存储介质。The present invention relates to the field of data communication in an LTE mobile communication system, and in particular, to a method, an apparatus, a core network, a system, and a storage medium for a terminal to switch between base stations in an LTE system.
LTE移动通讯系统中,S1切换是借助核心网网元,完成基站间业务迁移的业务处理方式。正常S1切换完成后,核心网会通知源侧基站发起上下文释放,如果发生S1切换失败场景,一般场景下核心网可能通知源侧发起上下文释放,或者没有任何通知,源侧基站主动释放。In the LTE mobile communication system, the S1 handover is a service processing method for performing service migration between the base stations by means of the core network element. After the normal S1 handover is complete, the core network notifies the source-side base station to initiate the context release. If the S1 handover fails, the core network may notify the source side to initiate the context release, or the source-side base station actively releases the information.
切换发生失败场景的上述处理方式是有问题。大多切换场景出现并不是因为源侧信号很弱,而是目的基站信号更强且达到切换门限导致,也就是说用户在源侧基站信号下进行业务是没有问题的,因为切换失败发起上下文释放,相当于主动掉话,这对用户感受是不好的。对于另外的场景,如果核心网没有任何通知,一般情况下,源侧基站因为缺乏了解核心网和目标基站的运行状态仍然认为处于切换过程中,因为不知道终端在目的基站的切换情况,为资源回收稳妥起见,会主动发起上下文释放,仍然相当于主动掉话。The above processing method of switching the failure scenario is problematic. Most of the handover scenarios occur not because the source side signal is weak, but because the destination base station signal is stronger and reaches the handover threshold. That is to say, the user performs the service under the source side base station signal, because the handover fails to initiate the context release. It is equivalent to active call drop, which is not good for the user. For other scenarios, if the core network does not have any notification, in general, the source-side base station is still considered to be in the handover process because it lacks understanding of the operating state of the core network and the target base station, because it does not know the handover situation of the terminal at the destination base station, and is a resource. Recycling is safe, and it will initiate a contextual release, which is still equivalent to active dropped calls.
