Abstract
A method for performing centralized radio access network (CRAN) process migration, wherein the CRAN comprises a number of remote radio access points and a centralized processing center including a number of physical compute hosts that perform at least part of a radio access network functionality, includes executing a CRAN process on a first of the physical compute hosts and starting a new instance of the CRAN process on a second of the physical compute hosts; duplicating traffic destined to the CRAN process to both instances of the CRAN process; during a first time interval, processing the traffic on the first and the second physical compute host in parallel and suppressing the output of the second physical compute host; and when the second physical compute host reaches a same state with respect to the CRAN process as the first physical compute host, forwarding duplicate outputs from both instances to higher layers.
