Abstract: Methods and systems are provided for establishing a logical flow path between a radio network controller (RNC) having multiple call processors that are operable in a distributed manner and a base station, in particular a Node B, being served by the RNC using an internet protocol (IP) transport technology. In some embodiments a method comprises configuring of IP addresses to be used by the RNC and base station, establishing paths based on communication ports in the RNC and base station, performing cell initialization and establishing common channel paths between the RNC and base station. Methods described herein include a step for Node B attachment that can be added to a Node B and RNC installation phase that is current part of 3GPP standards as part of a “plug and play” deployment method. The methods for Node B attachment to the network enable the Node B to be installed and dynamically registered with the RNC.

Abstract: Methods and apparatus for establishing connections between network nodes across an MPLS domain. A data receive node transmits to a data transmit node the service label that the data receive node expects to receive embedded in packets originating from the data transmit node. Any packet that has this service label by the data receive node will therefore be treated and considered by this data receive node as originating from the data transmit node.

Abstract: A method of using the existing radio resources to automatically determine the current cellular topology is described. Wireless basestations are placed into a mode where they can transmit a signal which can be received by all of the base stations in range of the transmitting basestation. Each base station in the system serially broadcast a signal which is received by all other basestations within the range of the transmitting basestation. Each of the receiving radios determines the RSSI (Received Signal Strength Indication) at which they received the transmitted signal. The RSSI values are used to determine which base stations are physically co-located into cells and then determine the relative locations of the cells to each other.

Abstract: A topology verification process for controlling a Personal Communication Services (PCS) system which includes a plurality of Cordless Fixed Parts (CFP)s. The process includes mapping the spatial relationships of the CFPs utilizing Received Signal Strength Indication (RSSI) vectors resulting from test signals transmitted between the CFPs, to establish the topology of the system; repeating the mapping process after any disruption of power to the system, and comparing the results. Any significant change in the results, would be highly indicative of a potential change in the geographic area of operation of the system, and can be used to initiate disablement of the system operation.
