Transformation Of EPC Core Network Of Jilin Unicom Based On Large Flow Rate

In the communication technology under the promotion of continuous upgrading,the mobile communication networks are transforming gradually from the voice area into a new one of data traffic.With the widespread application of smart phones and the continuous enrichment of mobile internet multimedia application,People are more inclined to shop online and watch video,therefore,users need a faster and more stable network.So far,the demand for voice service gradually becomes saturated and stable.“Internet plus initiative”、 “speed up and fee reduction” is a hot topic in China's communication industry,the decrease of mobile data traffic charges has greatly promoted the growth of user traffic.Telecom operators needs to be built urgently to improve the network capacity and meet the business needs of users,4G core network is usually concentrated in the provincial capital or core cities,user data needs to be converged to the provincial capital through IP private network and then connected to the core network,therefore,the rapid growth of data has posed a challenge to the bandwidth of IP private network.Telecom operators meet the explosive growth of data services by constantly expanding capacity and updating EPC core network equipment.This paper describes the development of mobile core network,make a detailed analysis of The main network element function、 interface、 protocol and network scheme principle of EPC network,combined with the explosive growth of user data and reduce the bandwidth pressure demand of IP private network,the network transformation demand of jilin EPC core network is analyzed,Clarified the principle of network transformation.The transformation was carried out in stages,On the basis of ensuring the normal operation of the network,network transformation is carried out,So as to realize the network better support business requirements.Through research analysis and practical certification,the feasibility of the scheme is proved.The research results have been applied in the current network,and the expected results have been achieved,which provides a reference and guidance for the future transformation work.At the same time,it is of great significance to the security operation and maintenance of the network.
