    Abstract: A UE (10) provides information on potential S′eNB(s). The information is forwarded from an MeNB (20_1) to an M′eNB (20_2) such that the M′eNB (20_2) can determine, before the handover happens, whether the M′eNB (20_2) will configure a new SeNB (S′eNB) and which S′eNB the M′eNB (20_2) will configure. In one of options, the MeNB (20_1) derives a key S′-KeNB for communication protection between the UE (10) and the S′eNB (30_1), and send the S′-KeNB to the M′eNB (20_2). In another option, the M′eNB (20_2) derives the S′-KeNB from a key KeNB* received from the MeNB (20_1). The M′eNB (20_2) sends the S′-KeNB to the S′eNB (30_1). Moreover, there are also provided several variations to perform SeNB Release, SeNB Addition, Bearer Modification and the like, in which the order and/or timing thereof can be different during the handover procedure.

    Abstract translation: UE（10）提供关于潜在S'NB的信息。 信息从MeNB（20_1）转发到M'NB（20_2），使得M'eNB（20_2）可以在切换发生之前确定M'eNB（20_2）是否将配置新的SeNB（S 'eNB）和M'eNB（20_2）将配置的S'eNB。 在一个选项中，MeNB（20_1）导出用于UE（10）和S'eNB（30_1）之间的通信保护的密钥S'-KeNB，并将S'-KeNB发送到M'NB（20_2） 。 在另一选择中，M'eNB（20_2）从从MeNB（20_1）接收的密钥KeNB *导出S'-KeNB。 M'eNB（20_2）将S'-KeNB发送到S'NB（30_1）。 此外，还提供了用于执行SeNB释放，SeNB添加，承载修改等的几种变型，其中顺序和/或定时在切换过程期间可以不同。

    Abstract: A secure system 1 includes a requesting device (L01) which requests a communication, and a receiving device (L03) which receives a communication request from the requesting device (L01). The requesting device (L01) and the receiving device (L03) are members of a specific group when the requesting device (L01) discovers the receiving device (L03). The requesting device (L01) is allowed to communicate with the requesting device (L01) by a network used by the specific group or by the receiving device upon a proof being provided by a network used by the specific group, the devices (L01) and (L03) being able to perform a mutual authentication over a direct wireless interface, or the receiving device (L03) checking a list maintained by a user on members of the specific group of devices for ProSe service purpose.

    Abstract: The present disclosure relates to method of enabling key re-usage for an electronic device. The method comprising: receiving a request message from the electronic device, wherein the request message comprises a first information being indicative of a preference for one of a first key associated with a first network node in a first network or a second key associated with a second network node in a second network; processing the request message to determine the preference indicated in the first information; and transmitting a response message to the electronic device for reusing the first key or second key, the electronic device is configured to derive a third key based on the first key or the second key as indicated in the determined preference, and the second network is able to access to the first key and the second key whereas the first network cannot access the second key.

    Abstract: In order for efficiently managing communications between a UE (10) and multiple SCSs (20_1-20_n), the UE (10) includes, in one message, multiple pieces of data to be transmitted to the SCSs (20_1-20_n), and sends the message to an MTC-IWF (30). The MTC-IWF (30) receives the message from the UE (10), and distributes the date to the SCSs (20_1-20_n). Each of the SCSs sends (20_1-20_n), to the MTC-IWF (30), data to be transmitted to the UE (10) and an indicator that indicates for the SCSs (20_1-20 n) the time tolerance until the data is transmitted to the UE (10). The MTC-IWF (30) receives the data and the indicators from the SCSs (20_1-20_n), and determines when to forward the data to the UE (10) based on the indicators.
