Description
Technical field
The present invention relates to the wireless network resource management technology, particularly relate to a kind of wireless broadcast communication UNE resource management system and method.
Background technology
Wireless broadcast network and cordless communication network all develop into sizable scale at present, take separate frequency bands separately between existing these two kinds of networks, respectively its resource are managed.Along with the development of communication network technology, realize the network integration of two kinds of business by technological transformation, and then comprehensive multimedia communication services such as comprising voice, data is provided is one of trend of present wireless network development.
When the fusion that relates between the network, how to realize that to the distribution of resource between two kinds of networks and management be wherein key technology, the resource allocation of indication here both can be the distribution of frequency, also can be the distribution of following time of same frequency.At present all wireless resource managements all are the management at single business network resource, as the resource management system in the cordless communication network, and the resource management system in the radio broadcasting net etc. and for example.In the prior art, the resource management system structure of cordless communication network as depicted in figs. 1 and 2, Fig. 1 is radio resource controller (RRC, Radio Resource Controller) and radio resource agent (RRA, Radio Resource Agent) is in broadband radio access network respectively and closes equipment (BWA GW, BroadbandWireless Access Gateway) and base station (BS, Base Station) wireless resource management under the situation, wherein, RRA is responsible for the resource management of BS in the radio communication, and to the monitoring of terminal communication resource requirement, and the communication resource demand information that monitoring gets access to transferred to RRC by the standard interface between RRA and the RRC, this standard interface is designated I2.RRC is responsible for collecting the communication resource demand information that each RRA sends, and between each RRC, transmit its communication resource load information in service area separately mutually by the standard interface between the RRC, this communication resource load information can be the loading condition in the service area, resource operating position etc., this standard interface is designated I3; According to the communication resource load information in the service area separately, consult the allocate communications resource between the RRC, realize the resource allocation in the communication network, and resource allocation information in the communication network is sent to RRA.Though, from the function application, also there is for example mobile services switching centre server (MSC Server in the core net on the BWA GW, Mobile Switching CenterServer), GPRS serving GPRS support node (SGSN, Serving GPRS Support Node) functional entity such as, finish the function such as routing forwarding, mobile management, session management of packet data package, but from the communication resource management angle, the BWA GW that contains RRC has been the root node of communication resource management system.
