Home Node B System Architecture with Support for RANAP User Adaptation Protocol

Abstract

Some embodiments are implemented in a communication system that includes a first communication system comprised of a licensed wireless radio access network and a core network, and a second communication system comprising a plurality of user hosted access points and a network controller. In some embodiments, each access point operates using short range licensed wireless frequencies to establish a service region. In some embodiments, the network controller communicatively couples the core network to the plurality of access points. The method uses three sets of protocol layers: a security layer, a transport layer, and a layer for transferring Radio Access Network Application Part (RANAP) messages, to communicate between the network controller and one of the access points. The method also uses the Iuh interface for the transport of messages across the three sets of protocol layers.

Benefits of technology

[0013]The network controller of some embodiments seamlessly integrates each of the short range licensed wireless service regions with the core network. In some such embodiments, the network controller seamlessly integrates with the core network by using existing Iu interfaces of the core network to communicatively couple each of the service regions to the core network. Accordingly, the network controller of some embodiments uses standardized messaging and protocols to communicate with the core network while utilizing HNB-AN messaging and protocols to communicate with each of the service regions. In this manner, the network controller of some embodiments reduces deployment costs of the HNB-AN within the UMTS core network. Specifically, deployment of the network controller of some embodiments requires no change to the UMTS core network while still providing HNB wireless service that combines the mobility of licensed wireless networks with the quality and speed of landline/broadband services. In some embodiments, the network controllers take on s

Problems solved by technology

The wireless transport mechanisms and frequencies employed by typical licensed wireless systems limit both data transfer rates and range.

However, with each upgrade iteration (e.g., 3 G to 4 G), the licensed wireless system providers incur substantial costs from licensing additional bandwidth spectrum to upgrading the existing radio network equipment or core network equipment.
