Embodiment

[0042] Embodiment specifically comprises the following steps:

[0043] Back up the data of ueIndex by HaBackupUeData(CC_UE_STRUCT_TYPE, ueNum, ueIndex, (&gp_CcCb->ueCbList[ueIndex], sizeof(CcUeCb)),

[0044] Call osp_send_ha_data_msg(OspHaMsg) after completing the package; the function sends the OspHaMsg data structure to the OpenSAF module.

[0045] After receiving the message, the OpenSAF module of the standby EPC system sends a message to the corresponding dtaskid. After receiving the message, the MME module first decodes the slice number, data length, data type, data identifier, and synchronization identifier, and transfers the data to the corresponding data structure in memcpy() , complete the data backup

[0046] In the modification of the "XGW module data backup and restoration" part, the XGW module data of the main EPC system is backed up to the backup EPC system, and the XGW module of the backup EPC system restores the data.

Abstract

The invention provides a data backup method for an LTE EPC (Long Term Evolution Evolved Packet Core) system. Two EPC systems: a master EPC system and a standby EPC system are set. The two EPC systems comprise EPC modules, OpenSAF modules and network devices. In a process of starting all processes of an EPC by a main EPC system, when terminals have service operation, each process stores data needing to be backed up to a corresponding slice number and sends backup data to the OpenSAF. After the standby EPC system starts the EPC, the backup data of the master EPC system is received, and each process receives messages and extracts and restores the data according to the slice numbers. If the standby EPC system does not start the EPC process, the OpenSAF stores the backup data of each process; each block of data corresponds to the unique slice number; and when backup is carried out on a certain slice number for N times, restoration is carried out for one time. The backup times is reduced; hot backup and cold backup are supported; real-time backup is realized; a partial backup and integrated backup function is realized for a data structure; and the backup and storage efficiency is improved.

Description

technical field [0001] The invention belongs to the communication field, and relates to a data backup method for an LTE EPC system. Background technique [0002] With the rapid development of communication technology, enterprises use computers to process their own core data. Since LTE (LongTerm Evolution, long-term evolution) has the characteristics of high speed, wide coverage, low delay, high concurrency, high stability, and fast mobility, it has great impact on business Continuity, real-time and stability requirements are very high. In order to improve work efficiency, reduce data disaster risk, reduce maintenance cost, enhance service quality, and ensure business continuity, the data backup method of LTE EPC system was invented. Contents of the invention [0003] The present invention provides a data backup method in an EPC (Evolved Packet Core: Evolved Packet Core Network) system to solve the problem of interruption of communication systems in scenarios such as rail t...
