Radio access management for a radio communication system which determines a power resource requirement for achieving a desired signal to interference ratio

摘要

The invention relates to access management in a radio communication system. A subscriber unit 101 transmits an access message to a base station 101 . A Radio Access Controller (RNC) 109 receives information of the access request. The RNC 109 comprises an interference characteristic processor 111 which determines an interference characteristic associated with the subscriber unit 101 . The interference characteristic may include an inter-cell interference factor and an intra-cell orthogonality factor determined as a function of the distance between the base station and the subscriber unit and/or based on subscriber unit measurements of pilot signals from the selected base station 103 and neighbouring base stations 105, 107 . The interference characteristic processor 111 is coupled to a resource requirement processor 113 which determines a resource requirement for achieving a desired signal to interference ratio for the requested service in response to the interference characteristic. The RNC 109 further comprises an access controller 115 which accepts or rejects the request in response to the determined resource requirement.
