Patent ID: 8180361

Claim:
A method 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 being served by the RNC using a connectionless internet protocol (IP) transport technology, the method comprising establishing connectionless call control paths, during base station installation, between the RNC and base station using request and response messaging initiated by the base station using the connectionless IP transport technology in an luB interface, prior to generating an SCTP (stream control transmission protocol) association; wherein establishing call control paths between the RNC and base station further comprises: the base station sending an attach request message comprising an identification of the base station, a base station Node B control port (NCP) number, a base station communication control port (CCP) number, and a transmission retry interval; and the base station receiving an attach response message comprising an RNC control plane IP address, an RNC NCP number and an RNC CCP number; and the base station forming SCTP (stream control transmission protocol) associations using the base station NCP-number, the base station CPP number, a base station control plane IP address, the RNC control plane IP address, the RNC NCP number and the RNC CCP number; and balancing a load on RNC processing resources, which further comprises the RNC selecting RNC ports and an RNC IP address dedicated to the base station for establishing at least one call control path, the selecting based-on awareness of previously allocated processing resources.
