Abstract
Systems, methods, apparatuses, and computer program products for providing cell configuration parameters in a secure manner are provided. A method may include providing, from a network node, cell configuration or other cell sensitive data to the internal memory of an authorized user equipment. For example, the providing may include providing the cell configuration or other cell sensitive data to the memory of the authorized user equipment as coded cell configuration package (CCCP) tracking area update (TAU) data during the configuration of the authorized user equipment or while the authorized user equipment is in radio resource control (RRC) connected state with the network node.
Claims3
An apparatus, comprising:
- at least one processor;
- and
- at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- provide cell configuration or other cell sensitive data to an authorized user equipment, wherein, to provide the cell configuration or other cell sensitive data, the apparatus is further caused to provide the cell configuration or other cell sensitive data to a memory of the authorized user equipment as coded cell configuration package tracking area update data during configuration of the authorized user equipment or while the authorized user equipment is in radio resource control connected state with the apparatus;
- and
- broadcast cell configuration information comprising altered cell parameters including false cell static or dynamic parameters or missing cell static parameters or offset from a real value of a parameter, wherein a maximum time needed to decode a correct cell configuration is a function of the number of the altered cell parameters and is calculated according to the following:
- DTSL(n,Rn,tSL)=tSLΠi=1nRi,
- where DTSL is a cell proper configuration detection time, n is a number of the altered cell parameters at a given security level, Rn is a parameter maximum value range, and tSL is a mean reattempt time in case of failed parameter value decoding at the given security level.
