Explanation

Barred

The IE is mandatory present if the IE "Cell Barred" has the value "Barred"; otherwise the element is not needed in the message.

Note1: If IE “function type” is set to “frequency scope1”, for “Map_parameter_1” and “Map_parameter_2”, this value is interpreted as the frequency which applys to the mapping relationship: (0, 99)-> (9400, 9499); for “Upper_limit”, this value is interpreted as the frequency which applys to the mapping relationship: (1, 91)-> (9400, 9490).
If IE “function type” is set to “frequency scope2”, for “Map_parameter_1” and “Map_parameter_2”, this value is interpreted as the frequency which applys to the mapping relationship: (0, 99)-> (9500, 9599); for “Upper_limit”, this value is interpreted as the frequency which applys to the mapping relationship: (1, 91)-> (9500, 9590).
If IE “function type” is set to “frequency scope3”, for “Map_parameter_1” and “Map_parameter_2”, only the value among (0, 75) is valid and interpreted as frequency which applys to the mapping relationship: (0, 75)-> (10050, 10125); for “Upper_limit”, only the value among (1, 75) is valid and interpreted as frequency which applys to the mapping relationship: (1, 75)-> (10050, 10124).

Note2: If IE “function type” is set to “RSCP threshold”, only the value among (0, 90) is valid and interpreted as P-CCPCH RSCP value which applys to the mapping relationship: (0, 90)-> ( -115, -25);
