Abstract: A mobile communication system includes a central processing unit coupled to a memory storing instructions for executing a User Equipment (UE) implemented by a transceiver and a controller that supports Proximity Services (ProSe), and a ProSe Function that supports the ProSe and communicates with the UE via a PC3 interface. The UE sends a message for a discovery to the ProSe Function via the PC3. The ProSe Function directly sends security information to the UE via the PC3. The UE directly sends a protected message to another UE an a PC5 interface using a key based on the security information.

Abstract: In order for making MTC more efficient and/or secure, a base station forming a communication system connects a UE to a core network. A node serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE. The node establishes, as a connection to the base station, a first connection for directly transceiving messages between the node and the base station. Alternatively, the node establishes a second connection for transparently transceiving the messages through a different node that is placed within the core network and has established a different secure connection to the base station.

Abstract: Phosphor, a preparation method for the phosphor, and a light emitting device having the phosphor. The phosphor comprises an inorganic compound which at least comprises an element M, an element A, an element D, and an element R; the element M is one or two elements selected from the group consisting of Lu, La, Pr, Nd, Sm, Y, Tb, and Gd and must comprise Lu; the element A is Si and/or Ge; the element D is one or two elements selected from the group consisting of O, N, and F and must comprise N; the element R is Ce and/or Dy. Since the ionic radius of Lu3+ is smaller than that of La3+, when the inorganic compound comprises element Lu, the original ligand site would be contracted. In order to reduce lattice distortion due to the ligand site contraction, the adjacent ligand site expands, and the photochromic property is adjusted.

Abstract: Upon receiving a triggering message from a MTC server (20), a network (10) verifies if the MTC server (20) is authorized to trigger a target MTC device (30) and also if the MTC device (30) is authorized to respond the triggering message, by comparing an MTC device ID and MTC server ID (and optionally information on subscription) which are include in the triggering message with authorized ones. Upon succeeding in the verification, the network (10) checks a trigger type included in the triggering message to verify if the triggering message is authorized to be sent to the MTC device (30). Upon succeeding in the check, the network (10) forwards the triggering message to the MTC device (30). The network (10) also validates a response from the MTC device (30), by checking whether the MTC device (30) is allowed to communicate with the addressed MTC server (20).

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.

Abstract: There is provided a network system including one or more first MMEs (30), and a second MME (40) separated from the first MMEs (30). In one of operation cases, the first MME (30) pushes, to the second MME (40), security context for a UE (10) that attaches to the first MME (30). The second MME (40) stores the security context. The first MME (30) further pushes the latest security context to the second MME (40), during a switch-off procedure for the first MME (30). The second MME (40) updates the stored security context with the latest security context. The first MME (30) pulls the security context from the second MME (40), when the UE (10) re-attaches to the first MME (30) or is handovered from different one of the first MMEs (30).

Abstract: In order for effectively ensuring security for direct communication in ProSe, a ProSe Function acquires from a 3rd party root keys for each of UEs to derive a pair of session keys for securely conducting direct communication with different UEs, and distributes the acquired root keys to each of the UEs. Each of the UEs derives the session keys by using one of the distributed root keys. Moreover, a plurality of UEs, which form a communication system, and are allowed to conduct direct communication with each other when the UEs are in proximity to each other, share public keys of the UEs therebetween through a node which supports the direct communication upon successfully registering the UEs with the node. Each of the UEs verifies at least a request for the direct communication by using one of the public keys.

Abstract: A mobile communication system for ProSe (Proximity Services) includes a plurality of User Equipments (UEs) that are in proximity and form a group for a ProSe direct communication, and a network that directly connects to the plurality of UEs. The plurality of UEs obtains a group ID from the network and sends a request message to the network. The network checks the plurality of UEs, derives a first security key related to the group, and sends a response message including the first security key to the plurality of UEs. The plurality of UEs derives a second security key based on the first security key and protects the ProSe direct communication by using the second security key.

Abstract: In order for more effectively supporting a Dedicated Core Network, there is provided a network system including a first node (30) that establishes secure connection with a UE (10) initially attempting to attach to a network, through a radio base station (20), and a second node (40) to which the UE (10) is redirected from the first node (30) through the radio base station (20). Upon the redirection, the first node (30) sends information on the first node (30) itself to the second node (40) through the radio base station (20). The second node (40) uses the information to retrieve security context necessary for establishing the connection with the UE (10) from the first node (30).

Abstract: There is provided a solution as to how the authentication and thus the authorization of the webRTC IMS Client can be achieved in the IMS of the mobile network operator. The WIC (20) is using an ID to register with IMS, which may be an IMPU, an IMPI, gGRUU etc. The WIC (20) may be preconfigured by the WWSF (30) with the eP-CSCF (40) address and authentication information, but if not, then this information should be retrieved via the WWSF (30) or from the IMS directly or via other device management procedures e.g. OMA DM. It is further assumed that the subscriber has already a valid webRTC account/membership and this can be validated, authenticated and authorized by the WWSF (30).
