摘要： The present invention overcomes the problem of S1 interface failure by redirecting user equipments to another radio basestation, or another RAT. This redirecting may be on a UE-by-UE basis, i.e. when a connection request is received, redirecting that UE, or may involve redirecting all UEs in a cell by broadcasting modified system information. The redirecting may be such that future traffic load, for example as caused by UEs performing tracking area updates, is minimized, by instructing UEs to redirect after a randomized period of time, or by locking the cell after a randomized period of time, for example. In yet further embodiments of the invention, the cell may be locked after a certain number of connection requests have been received. In this way, particularly busy cells can be locked sooner than would otherwise be the case.
摘要翻译： 本发明通过将用户设备重定向到另一个无线电基站或另一个RAT来克服S1接口故障的问题。 这种重定向可以在UE-by-UE的基础上，即当接收到连接请求时重定向该UE，或者可能涉及通过广播修改的系统信息重定向小区中的所有UE。 重定向可以使得例如由执行跟踪区域更新的UE引起的未来业务负载被最小化，通过指示UE在随机化的时间段之后重定向，或者通过在随机化的时间段之后锁定小区，例如 。 在本发明的另外的实施例中，在接收到一定数量的连接请求之后，单元可以被锁定。 这样，特别忙碌的单元可以比其他情况更快地被锁定。
