PACKET TRANSMISSION METHOD BETWEEN HETEROGENEOUS NETWORKS WHICH NORMALLY RECEIVES A DOWNLINK PACKET ALTHOUGH A MOBILE TERMINAL IS TRANSPORTED TO A HETEROGENEOUS NETWORK
PACKET TRANSMISSION METHOD BETWEEN HETEROGENEOUS NETWORKS WHICH NORMALLY RECEIVES A DOWNLINK PACKET ALTHOUGH A MOBILE TERMINAL IS TRANSPORTED TO A HETEROGENEOUS NETWORK
PURPOSE: A packet transmission method between heterogeneous networks is provided to prevent the fail of routing area (RA) update by a downlink packet by transmitting the downlink packet after the RA update in the circuit switched (CS) fallback.;CONSTITUTION: A serving general packet radio service (GPRS) support node (SGSN) (250) receives an RA update request message from a mobile terminal (100) which is transported from a second network to a first network (S310). The SGSN is a packet gateway (270) and transmits a message which requests that a downlink packet of the mobile terminal waits for transmission for a waiting time (S330). The SGSN updates the position of the mobile terminal (S340). The SGSN completes the RA update. The SGSN receives the downlink package from the packet gateway (S370).;COPYRIGHT KIPO 2013;[Reference numerals] (270) Packet gateway; (330) Mobile management device; (S310) RAU request; (S320) Packet data information; (S330) PDP context update request by setting a transmission standby time; (S332) Response; (S334) Downlink packet storage; (S340) Mobile device location update; (S350) RAU accept; (S352) RAU complete; (S360) Service request procedure; (S370,S372) Downlink packet transmission
