1. A method comprising:
- detecting departure from a first administrative domain during a position reporting session;
determining whether a first entity, configured to determine position, within the first administrative domain is inaccessible; and
if inaccessible, initiating signaling for a handoff for assignment of a second entity, configured to determine position, within a second administrative domain to continue the position reporting session.

Abstract
An approach provides signaling for administrative domain change during location tracking. Departure of a mobile node from a first administrative domain is detected during a position reporting session. It is determined whether a first, configured to determine position, within the first administrative domain is inaccessible. If inaccessible, signaling for a handoff is initiated for assignment of a second, configured to determine position, within a second administrative domain to continue the position reporting session.

17. An apparatus comprising:
-
a processor configured to detect departure from a first administrative domain during a position reporting session, and to determine whether a first entity, configured to determine position, within the first administrative domain is inaccessible; and a radio section coupled to the processor and configured to initiate signaling for a handoff for assignment of a second entity if the first entity is inaccessible, wherein the second entity is configured to determine position, within a second administrative domain to continue the position reporting session. - View Dependent Claims (18)

19. A method comprising:
-
receiving a message, from a mobile node, specifying information corresponding to a tracking session, upon the mobile node entering a new administrative domain from another administrative domain; identifying a new serving position server within the new administrative domain for serving the mobile node; and assigning a new position determining entity (PDE) within the new administrative domain for continuing the session in the new administrative domain. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. An apparatus comprising:
-
a communication interface configured to receive a message, from a mobile node, specifying information corresponding to a tracking session, upon the mobile node entering a new administrative domain from another administrative domain; and a processor coupled to the communication interface and configured to identify a new serving position server within the new administrative domain for serving the mobile node, the processor being further configured to assign a new position determining entity (PDE) within the new administrative domain for continuing the session in the new administrative domain. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)

42. A system comprising:
-
a node configured to receive a message, from a mobile node, specifying information corresponding to a tracking session, upon the mobile node entering a new administrative domain from another administrative domain; and a position determining entity (PDE) configured to determine location of the mobile node within the other administrative domain and to communicate with the node, wherein the node is further configured to identify a new serving position server within the new administrative domain for serving the mobile node, and to assign a new position determining entity (PDE) within the new administrative domain for continuing the session in the new administrative domain. - View Dependent Claims (43)
