Method of registering a location of an access terminal within a Femto network with a Macro network, and associated apparatuses
View Patent ↗In one embodiment, the method of registering a location of an access terminal within a Femto network with a Macro network includes sending, by a Femto in the Femto network, a message to the Macro network. The message includes a first indicator, a second indicator and an address of the Femto. The first indicator indicates the access terminal. The second indicator indicates to register the Femto address in association with the access terminal.
1. A method of registering a location of an access terminal within a Femto network with a Macro network, comprising:
sending, by a Femto in the Femto network, a message to the Macro network, the message including a first indicator, a second indicator and an address of the Femto, the first indicator indicating the access terminal, the second indicator indicating to register the Femto address in association with the access terminal, the second indictor indicating to maintain a session of the access terminal with the Macro network if the session is currently handled by the Macro network, the Macro network storing the Femto address in association with an identifier of the access terminal; and
receiving, by the Femto, a registration response message from the Macro network,
the Macro network using the Femto address included in the message to establish another session with the Macro network when the access terminal has left the Macro network and subsequently requests a session transfer after returning to the Macro network.
2. The method of claim 1 , wherein the second indicator is a flag in the message.
3. The method of claim 1 , wherein the second indicator is a message identifier identifying the message as a registration message.
4. The method of claim 1 , wherein the sending is performed in response to a trigger.
5. The method of claim 4 , wherein the trigger is receipt of a request for an access terminal identifier from the access terminal.
6. The method of claim 5 , further comprising:
receiving, by the Femto, an access terminal identifier in response to the message; and
sending, by the Femto, the access terminal identifier to the access terminal.
7. The method of claim 6 , wherein the sending the access terminal identifier further includes sending a color code associated with the Macro network.
8. The method of claim 4 , wherein the trigger is transfer of the session for the access terminal to the Femto from another Macro network.
9. The method of claim 4 , wherein the trigger is a connection request from the access terminal.
10. The method of claim 4 , wherein the trigger is a keep alive request from the access terminal, and the keep alive request requests that the session of the access terminal be maintained.
11. The method of claim 4 , wherein the trigger is transfer of the session for the access terminal to the Femto from another Femto.
12. The method of claim 4 , further comprising:
receiving, by the Femto, an access terminal identifier in response to the message; and
sending, by the Femto, the access terminal identifier to the access terminal.
13. The method of claim 12 , wherein the sending the access terminal identifier further includes sending a color code associated with the Macro network.
14. The method of claim 12 , wherein the sending the access terminal identifier further includes sending a color code associated with the Femto.
15. A method of registering a location of an access terminal within a Femto network with a Macro network, comprising:
receiving, at the Macro network, a message from the Femto, the message including a first indicator, a second indicator and an address of the Femto, the first indicator indicating the access terminal, the second indicator indicating to register the Femto address in association with the access terminal, the second indictor indicating to maintain a session of the access terminal with the Macro network if the session is currently handled by the Macro network;
storing, at the Macro network, the Femto address in association with an identifier of the access terminal; and
sending, by the Macro network, a registration response message to the Femto,
the Macro network using the Femto address included in the message to establish another session with the Macro network when the access terminal has left the Macro network and subsequently requests a session transfer after returning to the Macro network.
16. A Femto, the Femto configured to send a message to a Macro network, the message including a first indicator, a second indicator and an address of the Femto, the first indicator indicating the access terminal, the second indicator indicating to register the Femto address in association with the access terminal, the second indictor indicating to maintain a session of the access terminal with the Macro network if the session is currently handled by the Macro network, the Macro network storing the Femto address in association with an identifier of the access terminal; and
receiving, by the Femto, a registration response message from the Macro network,
the Macro network using the Femto address included in the message to establish another session with the Macro network when the access terminal has left the Macro network and subsequently requests a session transfer after returning to the Macro network.
