Definition

The IE MobilityStateParameters contains parameters to determine UE mobility state.

MobilityStateParameters ::=         SEQUENCE{
    t-Evaluation                        ENUMERATED {
        s30, s60, s120, s180, s240, spare3, spare2, spare1},
    t-HystNormal                        ENUMERATED {
        s30, s60, s120, s180, s240, spare3, spare2, spare1},
    n-CellChangeMedium                  INTEGER (1..16),
    n-CellChangeHigh                    INTEGER (1..16)
}

Fields (4)

FieldDescription
t-Evaluation
ENUMERATED { s30, s60, s120, s180, s240, spare3, spare2, spare1}
The duration for evaluating criteria to enter mobility states. Corresponds to T CRmax in TS 38.304 [20]. Value in seconds, s30 corresponds to 30 s and so on.
t-HystNormal
ENUMERATED { s30, s60, s120, s180, s240, spare3, spare2, spare1}
The additional duration for evaluating criteria to enter normal mobility state. Corresponds to T CRmaxHyst in TS 38.304 [20]. Value in seconds, value s30 corresponds to 30 seconds and so on.
n-CellChangeMedium
INTEGER (1..16)
The number of cell changes to enter medium mobility state. Corresponds to N CR_M in TS 38.304 [20].
n-CellChangeHigh
INTEGER (1..16)
The number of cell changes to enter high mobility state. Corresponds to N CR_H in TS 38.304 [20].
