Problems solved by technology

As a result, within the DSP 30#2, the processing of the user data transmission and reception section 32 is suppressed, and an abnormal state such as a response delay may be generated
[0014] On the other hand, because there is no line allocation to DSP 30#1, DSP 30#3 to DSP 30#n other than DSP 30#2 in the congested state, as shown in FIG. 4B, other DSPs 30#1, DSP 30 There is a margin in the processing from #3 to DSP 30#n, so the problem is that the load balancing or distribution at time t2 does not play a satisfactory role

[0043] FIG. 5 is a system block diagram showing a first embodiment of a radio network controller as a load balancing system which is one form of the present invention. In FIG. 5 , a radio network controller (RNC) 40 is connected to a higher layer or higher-level core network 41 while being connected to a lower layer or lower-level radio base station (Node-B) 42 . A mobile terminal (UE) 43 is connected to this radio base station 42 by radio.

[0044] The radio network controller 40 includes a CPU 50 configured as resource management means and DSPs 60 #1 to 60 #n configured as processing units.

[0045] The CPU 50 includes: a request reception section 51 for receiving a processing request for line allocation and line release from a higher-level or higher-level device, a DSP selection section 52 for selecting a DSP to which the processing request is to be sent, A request transmission section 53 for transmitting a processing request to a DSP selected as a request transmission des...

Abstract

PROBLEM TO BE SOLVED: To provide a resource control apparatus and a radio network controller using the apparatus which can prevent convergence of processing of a specific processor even when only an amount of resources used by the specific processor is decreased. ŽSOLUTION: The invention includes: a resource control means for managing an amount of resources used and an amount of virtual resources of each of plural processors; a selection control means for selecting a processor having a smallest sum of the amount of resources used and the amount of virtual resources in the resource control means in response to an external process request, increasing the amount of resources used by the selected processor in the resource control means and decreasing the amount of resources used by the processor corresponding to an external process release request in the resource control means, in response to the process release request; and a virtual resource control means for increasing the amount of virtual resources of the processor corresponding to the process release request in the resource control means, in response to the process release request to one of the processors.

Description

technical field [0001] The present invention relates generally to resource management devices and radio network controllers, and more particularly to resource management devices for managing resources that are processing capabilities of a plurality of processing units and radio (or wireless) network control using such resource management devices device. Background technique [0002] FIG. 1 is a system block diagram illustrating an embodiment of a general load balancing system. In FIG. 1, a CPU 1 is set as a resource management device, and devices 3#1 to 3#n (for example, digital signal processors (DSP)) set as processing units, a memory 4, and an interface 5 are connected via a bus 2 to that CPU 1. The CPU 1 manages the amount of resources used by each of the devices 3#1 to 3#n, and balances or distributes the load on the devices 3#1 to 3#n by monitoring the usage status of the devices 3#1 to 3#n. [0003] FIG. 2 is a system block diagram showing the structure of a radio ...
