Method for processing different user attach types by core network of evolved packet system

Abstract

The invention discloses a method for processing different user attach types by a core network of an evolved packet system. The method comprises the following steps: a mobile management unit receives an attachment request message which contains attach type parameters and is transmitted from user equipment, and then transmits the parameters to a service gateway; and the service gateway transmits the request message containing the attach type parameters to a packet data network gateway; and the packet data network gateway newly assigns an IP address to the user equipment or returns the IP address which is originally used by the user equipment to the user equipment for continuous use according to the attach types which are indicated by the attach type parameters. In the method, a user attaches one attach type parameter to an MME when initiating an attach request, the MME attaches the parameter to an S-GW, and the S-GW attaches the parameter to a P-GW, therefore, different attach types canbe distinctively processed correspondingly.

Description

Evolved Packet System Core Network's Handling Method for Different Attachment Types of Users technical field The invention relates to a method for processing different attachment types of users in an evolved packet system core network (Evolved Packet System, EPS for short) in the field of communication technology. Background technique The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) evolved packet system (EvolvedPacketSystem, referred to as EPS) consists of evolved UTRAN (EvolvedUniversalTerrestrialRadioAccessNetwork, referred to as E-UTRAN), mobile management unit (MobilityManagementEntity, referred to as MME), serving gateway (ServingGateway, S-GW for short), Packet Data Network Gateway PDNGW (PacketDataNetworkGateWay, P-GW for short), Policy Control and Charging Rules Function (Policy Control and Charging Rules Function, PCRF for short), Home Subscriber Server (Home Subscriber Server, HSS for short), 3GPP authentication, au...

AI Technical Summary

Problems solved by technology

Therefore, the 3GPP core network gateway devices S-GW and P-GW need to know whether the current user's attachment type is power-on attachment or handover attachment, and adopt different processing methods, but the above-mentioned core network gateway devices S-GW and P-GW in the prior art GW cannot know which attachment method the user is
