Abstract:
1. A method, comprising: establishing a communication coverage area map of at least a first and a second access point in a first communication network that uses a first communication protocol; communicating by a communication device with the first access point in a first coverage area via a first communication protocol; evaluating a position and heading of the communication device and whether the device is approaching a periphery of the first coverage area of the first access point; if a signal strength is below a handoff signal threshold, delaying handoff to determine whether the device will be heading into a second coverage area of the second access point dependent on the position and heading of the communication device; and shifting communications to a second communication protocol of a second communication network, if the device will not be heading into the second coverage area of the second access point, and otherwise shifting communications to the second access point of the first communication protocol when the device enters the second coverage area.
