g handovers 20 This can further be divided into the type of handover (S1/X2 handover). Toward the last 10 minutes of simulation, the number will be higher as many of the stationary users will be mobile and moving outward or inward. Number of data sessions/ subscriber Highway Model Simulation of a highway traffic model will require these considerations: The cell size should be considerably large. The average speed of a user will be high (around 70 to 100 kmph). The number of users will be lesser and the mobility of the users will be very high, with around 90% of the users involved in inward as well as outward mobility. It is possible that the cyclic prefix for the cells modeled around highway are of extended types as the cells are normally of larger size. User distribution is fairly uniform as the movement will be a particular direction on the highway. Table 1-11 presents a list of parameters and the values for the highway traffic model. CHAPTER 1 NETWORK PLANNING Table 1-11. Parameters for the Highway Traffic Model Parameter Values Comment Number of UEs For a highway model, the average number of UEs at a given time should be approximately 20 and the total throughput usage should be around 40% to 50%. User distribution Fairly uniform The user distribution for a highway model should be fairly uniform as the users will be moving along a specific path. Terminal speed 80% of the users are fast moving at a speed between 70 to 100 km per hour. 10% of the users are stationary 10% of users are slow moving at a speed of 3 kmph. Average number of session/ The assumption is that the average UE/busy hour (BH) duration of a session in highway area will be lower and the average number of sessions per user will be higher because of mobility and higher RLF. Number of E-RAB addition/ Based on the number of voice calls UE/BH during the BH, which would require one dedicated bearer setup. Low mobility users also make more calls than higher mobility users. Number of E-RAB Deletion/ Same assumption as above to remove UE/BH the dedicate
