Abstract: Various communication systems may benefit from the appropriate handling of transitioning between connections. For example, certain wireless communication systems may benefit from appropriate handling of further access attempts in a conditional handover scenario. A method can include receiving, at a user equipment, an access configuration information element configured to describe a user equipment behavior during an access phase of a conditional handover. The method can also include, upon detecting a failed access to the target for which the access condition has triggered, attempting to access a candidate cell among suitable candidate cells that have been previously configured for conditional handover.

Abstract: 本申请的目的是提供一种用于实现用户设备在无线接入点间切换的方法、设备与系统。与现有技术相比，本申请通过在网络设备端获取对应用户设备待切换的目标无线接入点，并确定所述目标无线接入点对应的接入信息，然后通过所述用户设备与对应当前无线接入点间的当前网络连接，将所述接入信息发送至所述用户设备，以供所述用户设备建立与所述目标无线接入点的无线连接，相应地，用户设备接收该接入信息，并根据该接入信息建立与目标无线接入点的无线连接。通过这种方式，实现了用户设备从当前连接的无线接入点到目标无线接入点之间的自动切换，并且利用用户设备与当前无线接入点间的当前网络连接预先发送接入信息，提高了切换效率，使用户在使用无线接入点时，特别是在移动过程中，也能实现无线接入点的自动切换。特别地，与通过改进无线接入点或用户设备来实现接入点间切换的技术方案相比，本方案不仅大幅降低了用户设备的能耗，也不需要改进每一个无线接入点，从而确保了本方案实施的可行性；而且，由于安全性或隐私性等因素，一个无线接入点通常是无法获取其他用户的无线接入点的接入信息的，而本方案通过网络设备来帮助用户设备获取目标无线接入点的接入信息，既避免了安全隐患，也扩大了本方案的适用范围。

Abstract: 本发明实施例提供了一种UMTS到LTE的网络切换方法、设备及系统，在共站的场景下，源RNC向UE下发的切换命令中包含了无需去目标小区进行RACH过程的指示，并且，由于提前预分配了UE发送切换完成消息的上行资源，并且提前由源RNC确定出了TA的值，将这三项内容都携带在切换命令中下发给UE，UE可以在接收到切换命令后，直接到目标小区进行接入，而不需要在目标小区内进行RACH过程，缩短了由于RACH过程带来的中断时延，同时也节省了RACH的相关资源。
