RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD

摘要

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. When the above type is data, the control unit (104) selects, on the basis of the result of the determination by the QoS determination unit (102), either a second establishment method for establishing radio bearers such that highest priority is given to achieving a high speed of the establishment, or a third establishment method for establishing radio bearers such that highest priority is given to achieving high efficiency in the use of radio resources.
