摘要： A communication system reduces set up time for an inter-technology handoff of a multi-mode mobile station (MS) from a source network associated with a first radio frequency (RF) technology to a target network associated with a second RF technology by pre-establishing, prior to a determination to handoff the MS, a registration state of the MS and an authentication of the MS in association with the target network and second RF technology. In order to pre-establish the registration state and authentication, the MS exchanges messaging of the second RF technology with the second network via the first network and first RF technology. To facilitate the exchange, the MS includes shims in a second protocol stack associated with the second technology, which shims intercept second protocol stack signaling and redirect the intercepted signaling to a first protocol stack of the MS, associated with the first technology, for tunneling to the source network.

摘要： A method (10) of establishing an alternate HRPD signaling link between and HRPD access network and an access terminal over a non-HRPD access is disclosed. It 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) (26); establishing (14) a data tunnel (28) between the access terminal (24) and the SFF (22); exchanging (16) HRPD signaling messages and HRPD data via the data tunnel (28); identifying (18) the HRPD access network (26) and the access terminal (24) over non-HRPD access by the SFF (22), by reading a header with certain identifiers and mapping the header to an address of the access terminal or network; and forwarding (20) the HRPD signaling messages and the HRPD data that arrive at the SFF (22) from the access terminal (24) and the HRPD access network (26) to the HRPD access network (26) and the access terminal (24), respectively. The method (10) performs an initiation and session establishment procedure, minimizes the time, disruption and packet loss during handoff to a HRPD access network and enables seamless mobility.
