"mobile Communications Network Radio Resource Management Techniques

"Communication in moving"is the most important characteristic of the tactics communication. In the "Communication in moving"network, not only is the mobile user moving, but also the Radio Access Point (RAP) and the whole network are moving. "Communication in moving"technology is to complete the real-time and dynamic management of the mobile user, to provide the technology support for establishing the communication link and the communication holding quickly between the users, and then to guarantee the normal communication when the RAP and the user are moving at random. This requires that the system must have the ability of mobility management to maintain the information about the network framework. Before one user is ready to send data to the other user, the destination user must be found quickly, and the link from the source user to the destination user must be established rapidly. That large numbers of signalings for maintaining the network topology information are transmitted among the network nodes needs some radio resource. And that communication of the users, including the user access and the transmission of the data packet, costs the most radio resource, too. Under the condition of limit radio resource, radio resource management is very important to support the normal communication of users. As far as the technology of radio resource management goes, traditional cellar network technology has reached full development, and Ad hoc network technology is rapidly developing. But there will be some limitations if these technologies are applied to the "Communication in moving"network. Focus on the characteristics of the "Communication in moving", such as the distributed framework, self-organized network and dramatically changed topology, this thesis puts forward a radio resource management strategy that considers both the terminal user access and the resource reservation for forwarding the packets of users, that is, the mobile user uses the improved Packet Reservation Multiple Access (PRMA) protocol to communication with its home RAP and the RAP uses the multiple channels reservation protocol to forward the data packet in the RAP network. When the communication environment is dramatically changed, the strategy can improve the radio resource utility and...
