[0176] Fig. 15 is a block diagram showing the structure of the mobile communication system according to the first embodiment of the present invention. In FIG. 15, the mobile communication system according to the first embodiment of the present invention includes RNC2, base stations 3-1 and 3-2, and mobile stations 4-1 to 4-4.

[0177] The mobile communication system according to the first embodiment of the present invention is a system such as a W-CDMA system in which HSDPA (High Speed ​​Downlink Packet Access), which is a high speed downlink transmission system, is used. When HSDPA is set, the downlink HS-PDSCH and DPCH must be set.

[0178] Here, DPCH is a separate channel for transmitting control data. Specifically, the DPCH configured when controlling the HS-PDSCH is called an associated DPCH. DPCH can be set independently, and user data can be sent on DPCH. The HS-PDSCH is a channel for transmitting user data as packets, which is shared by multiple users in a time-divi...

[0236] Fig. 21 is a block diagram showing the structure of a base station according to the second embodiment of the present invention. In FIG. 21 , base station 5 has the same structure as base station 3 according to the first embodiment of the present invention shown in FIG. 17 except that resource allocation judging unit 51 is provided instead of resource usage information transmitting unit 44 . Accordingly, like elements are denoted by like reference numerals. In addition, operations of the same elements are the same as those of the base station 3 according to the first embodiment of the present invention.

[0237] Although in the first embodiment of the present invention, the resource allocation judging unit is set in the RNC2, in the second embodiment of the present invention, it is set in the base station 5. The operation of the resource allocation judging unit in the second embodiment is the same as when it is set in RNC2. Note that the resource allocation judgment un...

[0252] Fig. 25 is a block diagram showing the structure of a base station according to a third embodiment of the present invention. In FIG. 25, the base station 7 has the same configuration as the base station 5 shown in FIG. Structure. Accordingly, like elements are denoted by like reference numerals. In addition, operations of the same elements are the same as those of the base station 5 according to the second embodiment of the present invention.

[0253] In the first embodiment of the present invention, the resource allocation updating unit, the allocation code information storage unit and the allocation power information storage unit are set in RNC2. However, in the third embodiment of the present invention, these units are provided in the base station 7, and their operations are the same as when these units are provided in the RNC2.

[0254] FIG. 26 is used to explain resource allocation control according to the third embodiment of the present invention. FIG. 26 show...

Abstract

A mobile communication system is provided which is capable of improving efficiency of use of allocated codes and allocated power of an HS-PDSCH to improve a throughput of the HS-PDSCH. A resource allocation update unit is connected to an RNC functional unit and a base station functional unit, performs allocation control of resources such as the number of codes and power, which are allocated or notified from the RNC functional unit to the base station functional unit, and stores allocation information of the resources in a resource allocation information storage unit. A resource use information detection unit detects a state of use of resources on the basis of a state of use of resources from the base station functional unit and a timing information from a timer, and informs a resource allocation judgment unit of the information on a state of use of resources. The resource allocation judgment unit judges whether or not allocation of resources has been updated on the basis of the information on a state of use of resources.

Description

[0001] This application is based on the application number 200410004222.7, the application date is February 10, 2004, the applicant is NEC Corporation, and the invention titled mobile communication system, base station, wireless network controller and resource allocation control method is a divisional application . technical field [0002] The invention relates to a mobile communication system, a base station, a wireless network controller and a resource allocation control method thereof. In particular, the present invention relates to the allocation of resources such as codes from radio network controllers to base stations in HSDPA (High Speed ​​Downlink Packet Access). Background technique [0003] Mobile communication systems such as W-CDMA (Wideband Code Division Multiple Access) use HSDPA, which is a high-speed downlink transmission system. When HSDPA is set, downlink HS-PDSCH (High Speed ​​Downlink Shared Physical Channel) and DPCH (Dedicated Physical Channel) must be...
