In such a context, mobile devices are equipped with multiple radio interfaces allowing connectivity to the most suitable network environment based on users' requirements and operators' policies.
In this sense, SDWN controllers become responsible for providing information sharing among operators, enabling better control of shared frequencies, and assuring that operators' policies are correctly applied.
As mentioned before, the values for the weights in Equation 1 are a direct translation of the operator policy.
The HSS grants the IMS access authorization to the UE after verifying one or more of the following criteria, as established by operator policy.
As shown in previous references, the specific objectives of traffic steering depend on operator policy, and they are achieved by utilizing mechanisms of mobility management, which are usually standardized by organizations such as the 3rd Generation Partnership Project (3GPP)[11].
The values for these weights are a direct translation of the operator policy, in the sense that they determine which of these metrics are more relevant and need to be minimized and which can be tolerated.
However, universal Location APIs still remain a challenge with the fragmentation of different APIs, devices and operator policies.
Such selections are based on the mobile battery saving, user preference, and operator policies.
Parameters ω cov, ω cap, and ω cost are weights to prioritize objectives defined according to operator policies.
Reducing U UL only when strictly needed is in line with operator policies, which only consider limiting the average PRB utilization in a cell under critical interference situations.
