METHODS AND APPARATUSES FOR TRANSMITTING CONTROL-PLANE MESSAGES IN CELLS USING DIFFERENT RADIO ACCESS TECHNOLOGIES (18204138)

Main Inventor

Hisashi FUTAKI

Brief explanation

The abstract describes a method for transmitting control plane (CP) messages between a radio station and a radio terminal in a second cell. The second cell uses a different radio access technology (RAT) than the first cell and is subordinate to it. The transmission of CP messages is triggered when a specific condition is met, such as the content or type of the message, the type of signaling radio bearer used, the transmission cause, or the type of core network associated with the message. This method aims to improve the efficiency of transmitting CP messages in a radio architecture that combines two different RATs.

Abstract

A radio station () transmits or receives, to or from a radio terminal () in a second cell (, ), a CP message containing a NAS message or an RRC message or both, when a predetermined condition is satisfied. The second cell (, ) uses a RAT different from that of the first cell, and is used in addition and subordinate to the first cell. The predetermined condition relates to at least one of: (a) a content or type of the CP message; (b) a type of a signalling radio bearer used to transmit the CP message; (c) a transmission cause of the CP message; and (d) a type of a core network associated with the NAS message. It is thus, for example, possible to contributing to efficient transmission of control plane (CP) messages in a radio architecture that provides interworking of two different Radio Access Technologies (RATs).

APPARATUS, SYSTEM AND METHOD FOR DC (DUAL CONNECTIVITY) (18204770)

Main Inventor

Xiaowei ZHANG

Brief explanation

The abstract describes a process in which a mobile device (UE) receives information about potential new base stations (S'eNBs) from its current base station (MeNB). This allows the new base station (M'eNB) to determine if it needs to configure a new S'eNB before the handover takes place. There are two options for establishing secure communication between the UE and the new S'eNB. In one option, the MeNB generates a key (S'-KeNB) and sends it to the M'eNB. In the other option, the M'eNB derives the key (S'-KeNB) from a key (KeNB*) received from the MeNB. The M'eNB then sends the key (S'-KeNB) to the S'eNB. The abstract also mentions variations in the order and timing of actions during the handover procedure, such as SeNB Release, SeNB Addition, and Bearer Modification.

Abstract

A UE () provides information on potential S′eNB(s). The information is forwarded from an MeNB (_) to an M′eNB (_) such that the M′eNB (_) can determine, before the handover happens, whether the M′eNB (_) will configure a new SeNB (S′eNB) and which S′eNB the M′eNB (_) will configure. In one of options, the MeNB (_) derives a key S′-KeNB for communication protection between the UE () and the S′eNB (_), and send the S′-KeNB to the M′eNB (_). In another option, the M′eNB (_) derives the S′-KeNB from a key KeNB* received from the MeNB (_). The M′eNB (_) sends the S′-KeNB to the S′eNB (_). 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.

ON-DEMAND SYSTEM INFORMATION BROADCASTING SYSTEM (18203373)

Main Inventor

Chadi KHIRALLAH

Brief explanation

The abstract describes a communication system that efficiently transmits system information. The system uses a base station to manage the transmission of this information on-demand, rather than periodically. This helps to reduce the signaling overhead associated with unnecessary transmissions. The base station can switch between on-demand and periodic transmission based on certain utilization thresholds, ensuring optimal resource usage.

Abstract

A communication system is disclosed in which a base station manages the transmission of on-demand system information to optimise the trade-off between the additional signalling overhead associated with on-demand transmission and the resource usage inefficiencies associated with the sometimes unnecessary transmission of system information on a periodic basis. The base station manages switching from on-demand transmission to periodic transmission, and vice versa, based on one or more utilisation thresholds.

RELAY DEVICE, TERMINAL, AND RELAY METHOD (18023115)

Main Inventor

Takuya SHOJI

Brief explanation

This abstract describes a relay device that is designed to prevent a terminal from connecting to an inappropriate system when there are failures in a base station. The device works by transmitting a connection request, along with authentication information, to a terminal that is connected to a network through the base station. If the terminal receives the connection request and approves the connection, it sends a notification to the relay device. Once the relay device receives this notification, it acts as a middleman and facilitates communication between the terminal and the network.

Abstract

In order to suppress a terminal from being connected to an inappropriate system when failures occur in a base station, this relay device comprises: a transmission means that, when failures occur in a base station, transmits a connection request including authentication information to a terminal connected to a network via the base station; a reception means that receives, from the terminal that has received the connection request, a notification indicating that connection is permitted; and a relay means that, upon being notified by the reception means that the notification has been received, relays communication between the terminal and the network.
