Summary:According to one aspect, a method performed by a first core network (CN) node in a telecommunications network is provided. The telecommunications network comprises a first radio access network (RAN) node operating according to a first radio access technology (RAT). There is a need to update a first security configuration between the wireless device and the first RAN node, the method comprising initiating (901) an emergency service fallback procedure to the second RAT after receiving a request for an emergency session from the wireless device that enables the wireless device to establish an emergency call. 根据一个方面，提供了一种由电信网络中的第一核心网络CN节点执行的方法。该电信网络包括根据第一无线电接入技术RAT操作的第一无线电接入网络RAN节点。需要对无线设备与第一RAN节点之间的第一安全配置的更新，该方法包括：在接收到来自无线设备的使得无线设备能够建立紧急呼叫的对紧急会话的请求之后，发起(901)向第二RAT的紧急服务回退过程。
