Method and apparatus for supporting location services for a roaming mobile station

A method of communication comprising:

• obtaining a first address of a first network entity for a first communication protocol;
• mapping a second address of a second network entity for a second communication protocol;
• and
• exchanging messages with a third network entity via the second network entity using the second address,
• wherein the first communication protocol comprises ANSI-41, the second communication protocol comprises Internet Protocol (IP), the first address comprises an ANSI-41 address, and the second address comprises an IP address.

A method of communication comprising:

• obtaining a first address of a first network entity for a first communication protocol;
• mapping a second address of a second network entity for a second communication protocol;
• and
• exchanging messages with a third network entity via the second network entity using the second address,
• wherein the first network entity is a serving mobile switching center (MSC) for a mobile station, the second network entity is a mapping server, and the third network entity is a serving mobile positioning center (S-MPC), and wherein the obtaining, the mapping, and the exchanging are performed by a home mobile positioning center (H-MPC).

A method of communication comprising:

• obtaining a first address of a first network entity for a first communication protocol;
• mapping the first address to a second address of a second network entity for a second communication protocol;
• and
• exchanging messages with the second network entity using the second address,
• wherein the exchanging messages with the second network entity comprises exchanging messages with the second network entity for location services for a mobile station roaming in a serving network different from a home network, and wherein the first address is provided by a roaming service provider (RSP) network to the home network.

A method of communication comprising:

• obtaining a first address of a first network entity for a first communication protocol;
