A method and device for realizing pgw process processing

Abstract

The invention discloses a PGW flow processing achieving method and device used for reducing the complexity of network element flow processing and reducing exceptional handling failure. The method comprises the steps that first request information used for indicating SGW building or specific bearer updating is sent to an SGW by a PGW; when being received by the PGW, second request information which is sent by the SGW and carries current UE position information is stored by the PGW, and response information of the second request information is directly sent to the SGW by the PGW; when response information, sent by the SGW, of the first request information is received and processed by the PGW, information which is stored locally and is relevant to UE is updated according to the stored current UE position information carried by the second request information. The PGW flow processing achieving method and device can reduce PGW flow processing achieving complexity, reduce processing fault rate and exceptional failure and improve PGW flow processing efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing PGW flow processing. Background technique [0002] In the agreement, the relevant description of the service request process triggered by the network side is: the serving gateway (Serving Gateway, SGW) receives the downlink data sent by the packet data gateway (Packet Data Network Gateway, PGW) (for example, to create a dedicated bearer request message or request message for updating the bearer), the SGW will send a downlink data notification message to the Mobility Management Entity (MME) or the Serving GPRS Support Node (SGSN), if the UE is in an evolved group In the EvolvedPacket System Connection Management, ECM-IDLE state, the MME or SGSN (Serving GPRSSupport Node, Serving GPRS Support Node) will trigger paging, and the UE will initiate a service request process. In the service request process, when the SGW judges that the location of the ...

Problems solved by technology

Therefore, it is difficult to implement and design, and the technical difficulty is high

[0031] Furthermore, the normal handover process and the handover process triggered by the nested service request, PGW cannot distinguish but cannot be processed uniformly, which will cause confusion in the internal processing process of PGW

[0032] Secondly, when the PGW processes the Modify Bearer Request message, it needs to further consider that after the location information of the UE changes, the PCC rules issued by the PCRF may also change accordingly. In this way, the PGW needs to trigger a new process after replying to the Modify BearerResponse message , to notify the UE to create or update a dedicated bearer according to the new PCC rules, which increases the difficulty of the PGW in the subsequent process processing
