Abstract

The invention provides a method for notifying overload between element locations, which is utilized by service gateways for notifying self overload situation to a moving management body. The method comprises sending overload notification to the moving management body when the service gateways detect self overload, wherein the overload notification carries identifiers of the service gateways. In answer to the overload notification, the moving management body adds the identifiers of the service gateways into an overload service gateway list, wherein service gateways in the overload service gateway list will not be chosen as service gateways of users. Through utilizing the method for notifying overload between element locations of the invention, load of the service gateway is reduced, overload balance between the service gateways is realized, failure rate of business establishment is reduced, and users' experience is enhanced.

Description

technical field

[0001] The present invention relates to the technical field of communications, in particular to an overload notification method between network elements. Background technique

[0002] The Evolved Packet System (EPS for short) system is a typical mobile communication system, such as figure 1 As shown, the entire EPS system is divided into two parts: a terrestrial radio access network system (Evolved UMTS, referred to as E-UTRAN) and a core network (Evovled Packet Core, referred to as EPC).

[0003] The EPC includes a Home Subscriber Server (HSS for short), a Mobility Management Entity (MME for short), a Serving Gateway (S-GW for short), and a packet data network gateway. (Packet Data Network Gateway, referred to as PDN-GW or P-GW), where:

[0004] HSS is the permanent storage location of user subscription data, located in the home network of user subscription;

[0005] MME is the control plane network element in the EPS network. It is the storage location o...
