Vertical network handovers

A method comprising:

• (a) intercepting an incoming call from a partner node so that the incoming call is not routed directly to a mobile terminal, the incoming call identifying the mobile terminal by a predefined public identifier;
• (b) determining, by a central server, whether the incoming call should be routed to the mobile terminal via one of a first wireless network and a second wireless network;
• (c) routing the incoming call to a first wireless interface of the mobile terminal via the first wireless network using a first secret identifier of the mobile terminal, if the first wireless network meets predefined criteria;
• and
• (d) otherwise routing the incoming call to a second wireless interface of the mobile terminal via the second wireless network using a second secret identifier of the mobile terminal, if the second wireless network meets the predefined criteria,
• wherein the first and second secret identifiers are associated with the predefined public identifier of the mobile terminal.

A method comprising:

• (a) detecting entry of a destination identifier corresponding to a destination node;
• (b) communicating the destination identifier to a central server via one of a first wireless network and a second wireless network;
• (c) causing the central server to establish communication with the destination node as a function of the destination identifier;
• and
• (d) causing the central server to switch the communication with the destination node to a mobile terminal via the one of the first wireless network using a first secret identifier of the mobile terminal and the second wireless network using a second secret identifier of the mobile terminal, thereby rerouting the communication session between the mobile terminal and the destination node, wherein the mobile terminal is configured to communicate with the first wireless network through a first wireless interface and with the second wireless network through a second wireless interface,
• wherein the first and second secret identifiers are associated with a single public identifier of the mobile device.

An apparatus comprising:

• a central server comprising:
• a processor;
• a memory;
• a switch;
• and
• multiple ports, in conjunction with the processor, memory, and switch, configured to communicate with a mobile device via an initial wireless network and via a different wireless network, and with a partner node to enable a communication session between a partner node and the mobile device via one of the initial wireless network using a first secret identifier of the mobile device and the different wireless network using a second secret identifier of the mobile device and configured to cause the communication session to be switched from an initial communication link between the partner node and the mobile device to a different communication link between the partner node and the mobile device thereby rerouting the communication session between the mobile terminal and the partner node,
• wherein the first and second secret identifiers are associated with a single public identifier of the mobile device.

A computer readable storage medium for storing computer program instructions that when executed by a processor perform operations comprising:

• (a) determining that an initial communication link via an initial wireless network between a central server and a first wireless interface of a mobile terminal is undesirable, wherein the central server is in communication with a partner node, enabling a communication session between the mobile terminal and the partner node through a first secret identifier of the mobile terminal;
• (b) establishing a different communication link via a different wireless network between the central server and a second interface of the mobile terminal through a second secret identifier of the mobile terminal;
• (c) causing the communication session to be switched from the initial communication link to the different communication link thereby rerouting the communication session between the mobile terminal and the partner node,
• wherein the first and second secret identifiers are associated with a single public identifier of the mobile terminal.
