Abstract
A composite quality measure helps determine a target for a vertical handover between different connection types. Various measurements are normalized, weighted and summed to produce composite quality measures. A composite quality measure may be compared to a target value and the corresponding connection may be added to a feasibility table if the composite quality measure is above the target.
Claims13
A method, comprising:
- communicating across a first wireless network of a first type;
- identifying a second wireless network of a second type, the second type different from the first type;
- prior to a handover decision, performing an authentication procedure with the second wireless network;
- based on the handover decision, performing a vertical handover from the first wireless network to the second wireless network,
- wherein said handover decision is based at least on a signal measurement corresponding to the second wireless network and a hysteresis parameter;
- and
- wherein the second wireless network is a WiMAX network.

An apparatus, comprising:
- a first interface to communicate across a first wireless network of a first type;
- a second interface to communicate across a second wireless network of a second type;
- a decision module to make a handover decision to perform a vertical handover from the first wireless network to the second wireless network;
- and
- a control module to, prior to the handover decision, perform an authentication procedure with the second wireless network;
- wherein the second wireless network is a WiMAX network.
