    • For personalizing a smart card (SC) coupled with a communication device (CD) of a user being a subscriber of a first telecommunication network (TN1) and wishing to become a subscriber of a second telecommunication network (TN2), a first international identity (IMSI_1) and a first authentication key (AK_1) being stored in the smart card (SC), the smart card receives a message (MesP) from an application server (AS) connected to the first telecommunication network and the second telecommunication network, the message (MesN) comprising a personalization command (ComP) and an admin code (ACas), after that the application server has received a request (Req) of subscription change comprising an identifier (1dMNO2) of the second telecommunication network (TN2) and has established a secured session with a personalization server (PS) of the second telecommunication network (TN2) identified by the identifier (1dMNO2), and interprets the personalization command (ComP) to establish a secure session with the personalization server (PS) via the application server (AS), if the admin code (ACas) is valid. The smart card negotiates with the personalization server to agree on an second authentication key, by exchanging messages containing values derived from random secrets, receives a message (Mes3) containing an second international identity (IMSI_2) from the personalization server (PS), and replaces the first international identity (IMSI_1) and the first authentication key (AK_1) by the second international identity and the second authentication key.

    • The invention is directed to a clock module and method for distributing a time reference to at least one clock in a packet-switched network. The clock module includes a slave port, a master port and a local clock. The method comprises the steps of receiving a first synchronization packet at the slave port, the first synchronization packet comprising a first master clock timestamp and generating at least one internal signal comprising the first master clock timestamp. The method also includes the steps of transmitting the at least one internal signal to the master port and receiving the at least one internal signal at the master port. Then a method includes determining the internal propagation time of the signal through the clock module and generating a second synchronization packet at the master port comprising a second master clock timestamp, the second master clock timestamp comprising the sum of the first master clock timestamp and the internal propagation time. Finally, the second synchronization packet is sent to at least one other clock in the packet-switched network.
    • 本发明涉及一种用于将时间参考分配给分组交换网络中的至少一个时钟的时钟模块和方法。 时钟模块包括从端口,主端口和本地时钟。 该方法包括以下步骤:在从端口处接收第一同步分组,第一同步分组包括第一主时钟时间戳,并且生成包括第一主时钟时间戳的至少一个内部信号。 该方法还包括将至少一个内部信号发送到主端口并在主端口处接收至少一个内部信号的步骤。 然后,一种方法包括确定通过时钟模块的信号的内部传播时间,并在主端口处产生包括第二主时钟时间戳的第二同步分组,第二主时钟时间戳包括第一主时钟时间戳和内部 传播时间。 最后,第二同步分组被发送到分组交换网络中的至少一个其他时钟。
