Seamless and vertical call handoff solution architecture

A method for facilitating handoff of communications with a user device between a first communication network having a first domain technology, and a second communication network having a second domain technology different from the first domain technology, the method comprising:

• generating a triggering event at an anchor point, the triggering event indicating to the user device that the user device is approaching a network boundary;
• establishing, at the anchor point, a first service flow with the first communication network, and a second service flow with the second communication network in response to the triggering event;
• during a pre-handoff stage:
• facilitating the establishment, by the anchor point, of an ad-hoc conference call between the user device and a remote party;
• initiating the second service flow to an agent of the anchor point;
• communicating at least an address of the remote party during service establishment between the user device and the remote party;
• establishing a handoff decision;
• and
• wherein the triggering event is a temporary signaling service set identifier (SSID) signal including network configuration information;
• and
• wherein a power profile of the temporary SSID signal overlaps a power profile associated with the first network and overlaps a power profile associated with the second network.

An anchor point for facilitating handoff of communications with a user device between a first communication network having a first domain technology, and a second communication network having a second domain technology different from the first domain technology, the anchor point comprising:

• a memory for storing network configuration data associated with at least one triggering event, the triggering event indicating to the user device that the user device is approaching a network boundary;
• a processor, the processor operating to:
• generate the at least one triggering event corresponding to a first service flow in the first communication network to commence a pre-handoff operation;
• establish a first service flow with the first communication network, and a second service flow with the second communication network based upon the at least one triggering event;
• receive at least one handoff parameter for determining a handoff operation of the user device from the first communication network to the second communication network;
• during a pre-handoff stage:
• facilitating the establishment of an ad-hoc conference call between the user device and a remote party;
• initiate the second service flow to an agent of the anchor point;
• communicate at least an address of the remote party during service establishment between the user device and the remote party;
• evaluate the at least one handoff parameter with a handoff device to establish a handoff decision;
• and
• wherein the triggering event is a temporary signaling service set identifier (SSID) signal including network configuration information;
• and
• wherein a power profile of the temporary SSID signal overlaps a power profile associated with the first network and overlaps a power profile associated with the second network.
