Embodiment Construction

[0022] (mobile communication system)

[0023] like figure 1 As shown, the mobile communication system 100 includes: a mobile station 10 , a base station 20 , a wireless control device 30 , a core network 40 , and a content server 50 .

[0024] The content server 50 performs MBMS (Multimedia Broadcast Multicast Service) for broadcasting or multicasting multimedia content to a plurality of mobile stations 10 . The content server 50 broadcasts or multicasts multimedia content and the like to a plurality of mobile stations 10 via the core network 40 , the wireless control device 30 , and the base station 20 .

[0025] The wireless control device 30 controls wireless communication between the base station 20 and the mobile station 10 . The base station 20 and the mobile station 10 perform wireless communication under the control of the wireless control device 30 . The mobile station 10 transmits and receives data or control signals with the wireless control device 30 or the cont...

Abstract

A radio network controller comprises a cell selector configured to select a cell to use by a mobile station after data reception, and a mobile station controller configured to control the mobile station to communicate by radio using the cell selected by the cell selector after the data reception.

Description

technical field [0001] The invention relates to a wireless control device, a mobile station and a mobile communication method. Background technique [0002] Currently, a service of broadcasting or multicasting multimedia content to multiple mobile stations (Multimedia Broadcast Multicast Service hereinafter referred to as "MBMS") (3GPP TSG-RAN, "TS25.346 V6.1.0 Interoduction of Multimedia broadcast multicast service (MBMS) in Radio access network (RAN)", June 2004). In MBMS, a mobile station is notified of a frequency of transmitting MBMS data via a radio access network (RAN: Radio Access Network). As a result, a mobile station that has not currently received MBMS data performs frequency switching to the notified frequency, and can receive MBMS data. [0003] However, after receiving MBMS data, a mobile station that has started using a specific frequency for transmitting MBMS data will continue to use the frequency range as long as the communication quality of the frequenc...
