The project is a centralized bidding project，The procurement content includes North and South regions、31Access to provincial core network equipment and network cloud resource pool equipment。
The maximum bidding price set for the project is tax exclusive11.58RMB100mn，Expected bid winner1individual。
Through cooperation with China Mobile，China Radio and television5GConstruction and operation will adhere to“Co construction and sharing、Uniform standard、Independent brand、Independent operation”Basic principles of，To build a“Thick in thin”Minimalist network，The core network deployment strategy will still adhere to independent construction。
according toDVBCNUnderstanding of，Previously, according to the plan of China Radio and television，Expected deployment5GIn the construction plan, it has been established to deploy radio and television according to the region5GCore network mode，Beijing was determined in advance、Nanjing/Shanghai、Guangzhou、Set the regional central node of the core network centered on the four regions of Xi'an，The network construction structure will follow the distributed architecture、Cloud deployment，And then cover the whole country。
in addition，On the core network technology strategy of radio and television，Based on their own conditions and reasons，All cloud architecture should be selected，Rely on signaling control surface to realize centralized deployment across the country，Then through the media forwarding surface to realize the deployment of provinces。
as everyone knows，China Radio and television has determined to work hand in hand with China Mobile700MHz 5GNetwork Co Construction and sharing，andDVBCNAlso learned，In the actual construction, China Radio and television will also promote the integration of fixed migration，Accelerate the upgrading and transformation of CATV Network。In the development of difference and innovation，China Radio and television will take media integration as the link，Play the role of radio and television in content、Platform advantages，Build up5GCharacteristic services of broadcasting。
As planned，China Radio and television and China Mobile have determined2021Year to2022Construction within two years48ten thousand700MHz 5GScheme of base station，This scale can basically meet the coverage of the whole country。Phased in progress，estimate2021Construction completed in20Wanji railway station，and2022Construction in28Wan Zhan。
It is worth noting that，In addition to local mobile companies and radio and television enterprises are accelerating700MHzOutside the pace of base station construction，Local radio and television are also being upgradedBOSSSystem and platform，Clearly put forward the right5G SAAnd other settlement requirements，Even faster deployment time in advance。
And what people are concerned about700MHzFrequency migration is also in accordance with“Edge construction、Side shift frequency、Side operation”The general idea of promoting，Previously, the project bidding for frequency migration construction and supervision has been carried out successively。DVBCNAlso learned exclusively，Specific work plan，2022By the end of the year, the national digital radio and television frequency migration will be completed in stages，At that time, a total of stations will be involved6000Multi seat、transmitter14000Many parts。Because the workload is still large，In the meantime2021In, priority can be given to completing the frequency migration of national backbone transmitting stations。
This time, China Radio and Television Corporation officially launched the nationwide centralized purchase of core network，It can be said to be radio and television5G 700MHzAnother substantive feat of building a network，Gradually spread out according to the early regional center，Radio and television can be provided later5GIndependent decision-making power in network signaling scheduling。of course，Radio and television5G“192”The number distribution of section can also be realized as soon as possible。
