Equipment reset notification method and equipment reset notification system, service and grouped data gateway and mobile management network element

Abstract

The embodiment of the invention provides an equipment reset notification method and an equipment reset notification system, a service and grouped data gateway and a mobile management network element. When the grouped data gateway is reset, the service gateway sends a notification message to the mobile management network element, and the mobile management network element sets relevant user-carriedcontext information as invalid or deletes the information; when the mobile management network element is reset, the service gateway sends the notification message to the grouped data gateway, and thegrouped data gateway sets user context information relevant to the mobile management network element as invalid or deletes the information; and when the service gateway is reset, the grouped data gateway sends the equipment-level identification of the mobile management network element to the service gateway, and the service gateway reestablishes carrier according to the equipment-level identification and the grouped data gateway. When one network element in a network is reset, the reset information is notified to other network elements to carry out corresponding processing; moreover, user context information of network elements can be restored through reestablishing public data network (PDN) connection or reattachment and the like to guarantee service quality.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a device reset notification method and system, a service and packet data gateway, and a mobility management network element. Background technique [0002] In the existing General Packet Radio Service (General Packet Radio Service; hereinafter referred to as: GPRS) / Universal Mobile Telecommunications System (Universal Mobile Telecommunications System; hereinafter referred to as: UMTS), when the GPRS support node gateway (hereinafter referred to as: GGSN) fails After reset, the packet data network connections (hereinafter referred to as: PDP context) of all users stored on the GGSN are destroyed and cleared, so normal business services cannot be provided. The existing solution is that if the radio network controller (hereinafter referred to as: RNC) receives the "GTP error indication" message sent by the failed GGSN, the RNC initiates a radio ac...

AI Technical Summary

Problems solved by technology

After the GGSN / SGSN is reset due to a fault, the GGSN / SGSN does not actively trigger the notification to the user to rebuild the PDP context or initiate the reattach process. business service quality

[0004] In the existing E-UTRAN evolution network architecture, since there is no interface between the Mobility Management Entity (hereinafter referred to as: MME) and the packet data network gateway (hereinafter referred to as: P-GW), the MME Or the other party cannot directly know after the P-GW is reset

[0005] In the process of implementing the present invention, the inventor found that: in the existing network system, after a network element in P-GW, MME and S-GW is reset, other network elements cannot obtain the reset information in time, resulting in service quality degradation or network failure. Defects such as meta work exceptions
