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. The Node B obtains access to distributed call processing resources from the RNC over public and IP networks to offer services to UEs that the newly attached Node B serves.
