  • Patent number: 9848334
    Abstract: In order for making MTC more efficient and/or secure, a base station (20) forming a communication system connects a UE (10) to a core network. A node (50) serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE (10). The node (50) establishes, as a connection to the base station (20), a first connection for directly transceiving messages between the node (50) and the base station (20). Alternatively, the node (50) establishes a second connection for transparently transceiving the messages through a different node (30) that is placed within the core network and has established a different secure connection to the base station (20).

  • Patent number: 9756390
    Abstract: A method of setting controls on a digital communication device operated by an end user of a digital communication network includes operating a gesture user interface on a set of content representations displayed on the digital communication device, where the set of content representations represents digital content associated with a broad range of content categories, to operate a preference profile generator to generate an initial control set for a ranking control. A tracking control is operated in the digital communication network to track activity of the digital communication device in a context of a digital content event to modify the initial control set for the ranking control into modified ranking controls. The modified ranking controls and content inputs from a digital content manager are applied to operate the ranking control and digital filter to generate a control interface for the digital communication device, the control interface comprising a plurality of individually operable controls.

  • Publication number: 20170245181
    Abstract: Upon requesting an MME (40) to handover a UE (10) to a Target MeNB (20_2), a Source MeNB (20_1) sends, to the Target MeNB (20_2) through the MME (40), information on one or more SeNBs that are candidates available for dual connectivity under control of the Target MeNB (20_2). The Target MeNB (20_2) configures a Target SeNB (30_2) that is selected based on the information to provide the dual connectivity. Alternatively, the Source MeNB (20_1) sends, to the Target MeNB (20_2), information on a Source SeNB (30_1) that has been used by the Source MeNB (20_1) for the dual connectivity. In this case, the Target MeNB (20_2) skips RRC configuration for the Source SeNB (30_1) upon the control.

  • Publication number: 20170201937
    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).

  • Publication number: 20170195305
    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).

  • Publication number: 20170156055
    Abstract: Upon transmitting privacy information to an MTC server (20) via a network (30, 40), an MTC device (10) includes in a message a field to indicate whether the message contains the privacy information, such that the network (30, 40) can perform authorization for the MTC device (10) and server (20). When the MTC device (10) needs to keep connection with the network (30, 40), the MTC device (10) switches off the functionality of provisioning the privacy information, such that the MTC device (10) still can communicate with the network (30, 40). Upon the transmission of privacy information in an emergency case, the MTC device (10) further includes in the message a content to indicate that the MTC device (10) is an emergency device, such that the network (30, 40) verifies whether the MTC device (10) can be used or activated in the emergency case. Optionally, a USIM for emergency-use is deployed in the MTC device (10).

  • Patent number: 9609597
    Abstract: The method is used in the AP, including: the AP suspending a high-speed bus directly when the terminal enters a standby state; the AP resuming the high-speed bus and inquiring a network connection state of the BP when the terminal is wakened; and if connection, the AP continuing to use a wireless data link, otherwise, the BP re-establishing a wireless data link. The method is used in the BP, including: the BP entering a standby state directly when the BP detects that a high-speed bus is suspended; the BP entering a wakening state after detecting that the high-speed bus is resumed, inquiring and feeding back a network connection state of the BP to the AP after receiving an instruction of inquiring the networking state of the AP; re-establishing a wireless data link or maintaining a wireless data link of a current networking after receiving a networking instruction of the AP.

  • Publication number: 20170085570
    Abstract: A network node (21), which is placed within a core network, receives a message from a transmission source (30) placed outside the core network. The message includes an indicator indicating whether or not the message is addressed to a group of one or more MTC devices attached to the core network. The network node (21) determines to authorize the transmission source (30), when the indicator indicates that the message is addressed to the group. Further, the message includes an ID for identifying whether or not the message is addressed to the group. The MTC device determines to discard the message, when the ID does not coincide with an ID allocated for the MTC device itself. Furthermore, the MTC device communicates with the transmission source (30) by use of a pair of group keys shared therewith.

  • Publication number: 20170078832
    Abstract: A network node (21), which is placed within a core network, stores a list of network elements (24) capable of forwarding a trigger message to a MTC device (10). The network node (21) receives the trigger message from a transmission source (30, 40) placed outside the core network, and then selects, based on the list, one of the network elements to forward the trigger message to the MTC device (10). The MTC device (10) validates the received trigger message, and then transmits, when the trigger message is not validated, to the network node (21) a reject message indicating that the trigger message is not accepted by the MTC device (10). Upon receiving the reject message, the network node (21) forwards the trigger message through a different one of the network elements, or forwards the reject message to transmission source (30, 40) to send the trigger message through user plane.

  • Publication number: 20170078940
    Abstract: An SeNB informs an MeNB that it can configure bearers for the given UE. At this time, the MeNB manages the DRB status, and then sends a key S-KeNB to the SeNB. The MeNB also sends a KSI for the S-KeNB to both of the UE and the SeNB. After this procedure, the MeNB informs an EPC (MME and S-GW) about the new bearer configured at the SeNB, such that the S-GW 50 can start offloading the bearer(s) to the SeNB 30. Prior to the offloading, the EPC network entity (MME or S-GW) performs verification that: 1) whether the request is coming from authenticated source (MeNB); and 2) whether the SeNB is a valid eNB to which the traffic can be offload.
