Algorithm 4

Validate request algorithm.

	Input: IMSI, V-RNTI value VUE received from UE
(ii)	Output: Boolean value stored in variable Valid
(1)	Valid = false
(2)	Locate V-table for V-RNTI range where:
(3)	SUE ≤ VUE ≤ (SUE + MUE)
(4)	If a particular range is found
(5)	If (VUE ≠ SUE and VUE ≠ MUE)
(6)	Valid = True
(7)	End if
(8)	End if
(9)	Return Valid
