Abstract  Abstract

A method (10) for establishing an alternative HRPD signaling link between an HRPD access network and an access terminal via non-HRPD access is disclosed. The method includes providing (12) a signal forwarding function (SFF) (22) between an access terminal (AT) 24 and a high rate packet data (HRPD) access network (AN) 24; Establishing (14) a data tunnel (28) between the access terminal (24) and the SFF (22); Exchanging (16) HRPD signaling messages and HRPD data over the data tunnel (28); Accessing the HRPD access network (26) and the access terminal (26) by a non-HRPD access by the SFF (22) by reading a header with predetermined identifiers and mapping the header to an address of the access terminal or the access network 24); And the HRPD signaling messages and the HRPD data arriving from the access terminal 24 and the HRPD access network 26 to the SFF 22 to the HRPD access network 26 and the access terminal 24, And forwarding (step 20). The method 10 performs initiation and session establishment procedures, minimizes time, confusion and packet loss during handoff to the HRPD access network, and enables fault-free mobility.
