A method and system for application data caching at cellular network

摘要

□ The cellular network provides voice service and data service for UEs. For data service, it serves UEs with communication channel between UE and application servers which is located in another network, usually the Internet. The cellular network includes radio access network(RAN), the core network and the authentication of users via SIM (subscriber identity module) cards. For LTE celluar network, the RAN consists eNBs and the core network includes MME, sGW, pGW and other nodes, as showing in figure 1. A typical communication channel between a UE and an application server in internet passes through the RAN, core network then towards application via Internet.
