Abstract: A core network device which manages an MBS session, the core network device includes a control unit that checks whether or not it is necessary to make an interact regarding a policy to be applied to the MBS session to a first core network device that controls the policy upon configuring the MBS session; and a communication unit that acquires specific information for identifying the first core network device from a second core network device that discovers a function present in a core network when it is necessary to interact with the first core network device regarding the policy, wherein the control unit identifies the first core network device based on the specific information, and the communication unit transmits, to the identified first core network device, a message for making the interact regarding the policy to be applied to the MBS session.

Abstract: A mobile relay node according to an aspect of the present disclosure includes: a memory storing a program; and one or more processors configured to execute the program to: communicate with a base station via a Uu interface as a user equipment; and communicate with one or more user equipments via a Uu interface as a base station, wherein a handover procedure for a handover of a target user equipment between the mobile relay node and each base station is performed via an Xn interface.

Abstract: The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

Abstract: Provided is a radio communication apparatus capable of reducing power consumption of user equipment by improving efficiency in the use of radio resources even in a case when a network node and the user equipment hold a plurality of bearer contexts shared therebetween. The apparatus comprises an information determination unit (101), a QoS determination unit (102) and a control unit (104). The information determination unit (101) determines whether the type of information to be transmitted is signaling or data. When the above type is data, the QoS determination unit (102) determines, on the basis of the QoS for the information to be transmitted, whether or not the information to be transmitted requires real-time transmission. When the above type is signaling, the control unit (104) selects a first establishment method for establishing just a signaling connection, without establishing a radio bearer, between the apparatus and a communication counterpart thereof.

Abstract: Systems, apparatus and methods for resource limitation in wireless networks are disclosed. The invention addresses the problem of allowing all network users at least some network resources during emergency and other similar situations. The invention transfers filters used for communications from guaranteed bit rate radio bearers to non-guaranteed bit rate radio bearers upon indication of emergency or other similar situations.
