Method and Apparatus for Home Node B Registration using HNBAP

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 sends a registration request from an access point to a network controller with location information and an identifier for the access point. The method receives at the access point a response when the access point is permitted to access the services of the network controller.

AI Technical Summary

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 some of the functionality of a traditional Radio Network Controller (RNC).

[0014]Additionally, the access points of some embodiments seamlessly integrate with existing user equipment (UE) of the licensed wireless radio access networks of the second communication system. In this manner, the access points reduce deployment costs of the HNB-AN, as users are able to utilize existing UE in order to wirelessly communicate through either the first communication system or the second communication system where the first communication system combines the wireless mobility afforded by the licensed wireless radio access network of the second communication system with the speed and quality of service afforded by landline / broadband services. In some embodiments, the access points are functionally equivalent to a Node-B of the UTRAN while having the flexibility and lower deployment costs associated with an ad-hoc and user hosted service region. In some embodiments, the access points take on some the functionality of a traditional Radio Network Controller (RNC).

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.

Users also incur equipment costs with each iterative upgrade of the licensed wireless network as new user equipment is needed to take advantage of the new services or improved services of the upgraded network.

The problem with landline connections is that they constrain the mobility of a user.

However, other UMA associated costs remained an obstacle to the large scale adoption of UMA.
