Problems solved by technology

Since the hardware resources of the radio base station apparatus are fixedly reserved, in the case of intermittent data transmission, hardware resources are reserved but not used.
If the same method as the DCH method is used to ensure the hardware resources of the wireless base station device for packet calls such as the E-DCH method, which has a higher maximum transmission rate than the DCH method, the utilization efficiency of the hardware resources will be further deteriorated.

[0041]

[0042] figure 1 An example of a wireless communication system according to this embodiment is shown.

[0043] The wireless communication system has: a wireless control device 100 1 -100 j (j is an integer of j>0), the radio base station apparatus 200 1 -200 k (k is an integer of k>0), and the mobile station device 300 1 -300 m (m is an integer of m>0). wireless control device 100 1 -100 j Connect with the core network (CN: Core Network) 10 . The core network 10 may include a switching station device 20 (not shown). wireless control device 100 1 -100 j Execution with the wireless base station device 200 1 -200 k and mobile station device 300 1 -300 m Controls related to the wireless communication performed between them.

[0044] figure 1 In, by the wireless base station device 200 1 -200 k Covered sectors are respectively sector 400 1 -400 k express. 400 in each sector 1 -400 k In , a limited number of cells with different carrier frequencies ov...

Abstract

A radio network controller for a wireless communication system, in which a dedicated channel and an enhanced dedicated channel are switched and assigned for an uplink for each call, includes a throughput estimation unit that estimates a throughput, wherein the throughput is expected when the enhanced dedicated channel is assigned to a call to be transmitted by a mobile station to which the dedicated channel has been assigned and / or to a call to be transmitted by a mobile station that initiates a communication; a packet access scheme selection unit that selects the enhanced dedicated channel, when the throughput estimated by the throughput estimation unit is greater than or equal to a predetermined threshold value; and a packet access scheme setting unit that sets the enhanced dedicated channel, when the packet access scheme selection unit selects the enhanced dedicated channel.

Description

technical field [0001] The present invention relates to wireless communication systems. Background technique [0002] In recent years, W-CDMA (Wideband- Code Division Multiple Access, wideband code division multiple access) (for example, refer to Non-Patent Document 1). Furthermore, HSDPA (High Speed ​​Downlink Packet Access) for improving downlink communication speed is also introduced in this W-CDMA (for example, refer to Non-Patent Document 2). In addition, in this W-CDMA, enhanced uplink (EUL: Enhanced Uplink) for improving uplink communication speed is also introduced (for example, refer to Non-Patent Document 3). [0003] In W-CDMA, a method using a dedicated channel (DCH: Dedicated Channel) is adopted as a packet access method (uplink packet access method) in the direction (uplink direction) from the mobile station device to the wireless base station device (hereinafter referred to as "DCH mode"). In W-CDMA with EUL introduced, as a packet access method in the upl...
