METHOD OF ESTABLISHING HRPD SIGNAL LINK Russian patent published in 2012 - IPC H04L12/56 H04W36/14 

FIELD: information technology.

SUBSTANCE: method includes providing a signal forwarding function (SFF) between an access terminal (AT) and a high rate packet data (HRPD) access network (AN); establishing a data tunnel between the access terminal and the SFF; exchanging HRPD signalling messages and HRPD data via the data tunnel; identifying the HRPD access network and the access terminal over non-HRPD access by the SFF, by reading a header with certain identifiers and mapping the header to an address of the access terminal or network; and forwarding the HRPD signalling messages and the HRPD data that arrive at the SFF from the access terminal and the HRPD access network to the HRPD access network and the access terminal, respectively. The method performs an initiation and session establishment procedure, minimises the time, disruption and packet loss during handoff to a HRPD access network and enables seamless mobility.

EFFECT: complexity and cost limitations for a mobile divide are reduced.
