Hi, There are only two frame types FDD and TDD, no such separate frame for CP or DP, contents may change depends on Control or Data information
why Ciphering is done for both user plane and control plane data, why not integrity done for both data in PDCP protocol
LTE is whole IP and for IP both the control and user plane are in anyway 2 different paths for packet transmission so I would to know why there is a need for the control and user plane differentiation.
What things forces to use GTP protocol for the user plane ? Is there any alternative design/approach which does not mandate to use GTP tunneling for the data transmission ?
