Method and Apparatus for Setup and Release of User Equipment Context Identifiers in a Home Node B System

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 covers the sending of a registration request for a user equipment from an access point to the network controller and receiving a registration accept response with a unique identifier for the user equipment allocated by the network controller.

AI Technical Summary

Benefits of technology

"The patent describes a method for integrating a first communication system with a core network of a second communication system using short range licensed wireless frequencies. The first communication system includes access points and a network controller that seamlessly integrates with the core network. The network controller uses standardized messaging and protocols to communicate with the core network while the access points utilize existing user equipment of the second communication system. The method reduces deployment costs and allows for the integration of the first communication system with the second communication system without changing the core network. The patent also describes a computer program for generating a message to the network controller to indicate the start of a communication session and a computer program for passing RANAP messages to the core network through the network controller."

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.
