Interward And Inward Network Policy

Operators are responsible for constructing the TS policy based on the targeted TS objective in any particular location for any particular instance. TS policy will assist user’s device to participate in TS operation for achieving the desirable TS objective. Each TS policy has some upward network status sub-factor (NSF_U) and some downward network status sub-factors (NSF_D). TS policy prefers higher values of NSF_U and lower values of NSF_D. Table I represents the considered upward and downward factors for each TS policy. • Enhancement: In order to fulfil the users’ satisfaction requirement, network must ensure the QoS requirement of the users. For enhancing QoS and service experience, users’ throughput demand should be met, which can be…show more content…
Once different network factors are identified and users profile is constructed, utility function is used to present different domains parameters on a single platform. In this paper, sigmoidal form of utility function [21] is used for TS policy’s utility value evaluation. where and corresponds to upper bound, lower bound, and tuning parameter respectively. Based on the user profile these values are determined. The parameters and are the tuned steepness, modeling user sensitivity to network status variation. NSF_U utility value is calculated by (1), whereas NSF_D utility value is obtained by (1- ). Each TS policy has a different combination of NSF_U and NSF_D, based on the TS policy requirements. Equation (2-4), representing the TS policy utility value for enhancement, utilization, and reduction at the same NAP. where and represent different combination of NSFs in TS policy. is weighting factors for different NSFs based on user profile. For a given user in any instance the available options for making decision same as (5), when operator considers not only the mentioned policies but also other different policies which may be defined in future. The column and row of this matrix indicate policy and available NAPs respectively for a given user. When policy is triggered by the operator the optimal destination for a given user under that policy
