Abstract:
1. A method of connecting network elements to a radio system comprising one or more network elements, a base station controller and a network management system that are operatively interconnected by means of telecommunication connections comprising traffic channels and control channels, and in which system information between the network elements is transmitted in frames that are divided into time slots, and in which system the base station controller controls one or more network elements, and network element identification information has been fed into a network element to be installed, and in which method the network element is physically connected to the system by means of the telecommunication connections, wherein in frames used by the base station controller for communication with the network elements, unused consecutive time slots of the frames being divided into one or more groups, and each group having one time slot within the group used as a bi-directional communication channel as regards time slot allocation from said group, and predetermining identification information for the base station controller about network elements allowed to be connected thereto, and after being physically installed, the network element to be installed searching the frames received by means of the telecommunication connections for the bi-directional communication control channels of the groups and identifying free groups by means of the bi-directional communication channels found, and the network element transmitting over the bi-directional communication channel of the group its identification information and hardware information to the base station controller wherein the base station controller comparing the identification information with the identification information about the allowed network elements, and when the identification information is allowed, accepting the network element, and the base station controller allocating from the group necessary time slots for the use of communication between the network element and the base station controller and informing the network element of the allocated time slots over the bi-directional communication control channel, and the allocated time slots being branched by software through the telecommunication connections to the network element.
