In this paper firstly current state and progress of LTE-based public safety network construction project is described, secondly emerging issues with designing LTE high-speed railway network are discussed, and finally a conclusion and future works are addressed. Two LTE networks are several similar features of LTE for public safety based radio access technology, 700 MHz frequency band, 10 MHz bandwidth, and nationwide deployment. Since the inter-network interference can cause the call disconnection with wireless train control which results in a fatal train accident, it is the most important thing at present for designing and planning LTE railway network to eliminate?봭ot to mitigate or reduce?봳he radio interference, and therefore in our view it urgently needs to secure the reliability and survivability of the wireless train control system when we design and deploy both LTE networks together.
