Patent ID: 8195159

Claim:
A method comprising: a first radio network controller (RNC) receiving from an access terminal a session-establishment request, wherein the session-establishment request requests establishment of a session for the access terminal; the first RNC determining that the session-establishment request indicates that the access terminal does not currently have a session with the first RNC, and responsively querying each RNC in a set of two or more RNCs to determine whether the access terminal currently has a session with an RNC other than the first RNC, wherein the set includes a second RNC, wherein querying each RNC in the set comprises querying the second RNC to determine whether the access terminal currently has a session with the second RNC, wherein the access terminal does currently have a session with the second RNC; after querying the second RNC, the first RNC receiving session data from the second RNC, the session data corresponding to the session that the access terminal currently has with the second RNC; and the first RNC using the received session data to set up a session with the first RNC for the access terminal.
