Abstract:
1. A network resource management system comprising: a first radio control apparatus connected to a radio base station device through a first interface through which data is transmitted and received in units of transport blocks through an IP transport; and a second radio control apparatus connected to said first radio control apparatus through a second interface through which the data is transmitted and received through the IP transport, wherein said second radio control apparatus transmits a protocol message to said first radio control apparatus, said protocol message containing radio parameters that include a maximum number of blocks transmitted in a transport block set which is a set of the transport blocks, a size of the transport block, and a time interval at which the transport block set is transmitted, and said first radio control apparatus defines a first factor which is an average value of the transport blocks and a second factor which is an average value of a data size of a particular portion of the IP transport, the first and second factors being previously acquired for data transmitted in the transport block set, said first radio control apparatus multiplies a maximum bit rate of the transport block by the first factor to calculate the amount of data on a user plane, the transport block being derived on the basis of the maximum number of blocks, the size of transport blocks, and the time interval which are included in the protocol message received from said second radio control apparatus, said first radio control apparatus divides the data size of the particular portion of the IP transport by the time interval, and multiplies the resulting value of the divide by the second factor to calculate the amount of data in the particular portion of the IP transport, and said first radio control apparatus uses the sum of the amount of data on the user plane and the amount of data in the particular portion as a band accumulated value for connection admission control in the first and second interfaces, and executes assignment of resources in the first and second interfaces when the band accumulated value is within a defined band, and rejects the assignment of resources in the first and second interfaces when the band accumulated value exceeds the defined band.
