Method for processing downlink data message of packet radio gateway equipment and device thereof

Abstract

The invention discloses a method for processing a downlink data message of packet radio gateway equipment. The method comprises the steps as follows: the packet radio gateway equipment receives the downlink data message of a user; the packet radio gateway equipment judges whether the packet radio gateway equipment itself is the packet radio gateway equipment which the user is accessed to according to a user IP address of the downlink data message; if the packet radio gateway equipment itself is the packet radio gateway equipment which the user is accessed to, the downlink data message is sent to the user; otherwise the downlink data message is transmitted to related packet radio gateway equipment according to a preset related gateway equipment information list. The invention also discloses a packet radio gateway device. The invention improves the success ratio greatly of right route of the downlink data message which is sent to the user signed with a static IP address to the user.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a downlink data packet processing method and device of a wireless packet gateway device. Background technique [0002] In the packet data network of General Packet Radio Service (GPRS, General Packet Radio Service) / Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunication System), user equipment (UE, User Equipment) tunnels through GPRS Tunneling Protocol (GTP, GPRSTunneling Protocol) Access to packet data networks. When the user establishes a GTP tunnel, the user request carrying the access point name (APN, Access Point Name) is first sent to the service GPRS support node (SGSN, Service GPRS Support Node), and the SGSN connects with itself according to the APN in the user request Select a GGSN among a plurality of gateway GPRS support nodes (GGSN, Gateway GPRSSupport Node), set up a GTP tunnel with it, and save the packet data protocol (PDP, Pa...

Problems solved by technology

However, since there is no effective solution for changing the route from the data-carrying network to the user, in the prior art, users who subscribe to a static IP address generally can only access one GGSN fixedly, and the user's uplink and downlink data messages are all passed through the fixed access If the GGSN that the user accesses is not the fixed access GGSN, the success rate of correctly routing the downlink data packets for the UE to the UE is very low
