The invention discloses a downlink signaling
message flow processing method and a
system, so that the problems that in the prior art, packet gate way (PGW) is large in flow
processing difficulty, signaling interaction between network elements is frequent, and
information processing flows are complex are solved. The method comprises the following steps: after the PGW receives
internet protocol (IP) connecting visit network conversation modification request messages sent by a
policy and charging rules function (PCRF)
network element, and sends downlink signaling request messages to a
signal gate way (SGW); after the SGW receives the downlink signaling request messages, and when user experience (UE) position information changes, the SGW stores the current UE position information and sends downlink signaling response massages carrying with the current UE position information to the PGW; after the PGW receives the downlink signaling response massages, the PGW sends IP connecting visit network conversation modification response messages not carrying with the current UE position information to the PCRF
network element; and the PGW sends the current UE position information to the PCRF
network element. According to the downlink signaling
message flow processing method and the
system, PGW processing difficulty is reduced, and downlink signaling
massage flow processing is simplified.
