An adaptive location management scheme for mobile broadband cellular systems

Adaptive paging schemes for group calls in mobile broadband cellular systems

“…Thus, if this prediction is accurate, the number of location updates messages is reduced, as it is shown in Ref. 2.…”

“…On the other hand, when the call arrives, the mobility manager must page all the cells in that LA (paging). Thus, increasing the number of cells that belong to a LA implies a reduction in the number of location updates, but an increase in the paging cost, defined as the number of paged cells required to locate the user 1, 2.…”

“…The heterogeneity of networks, devices, and even applications, suggests the need of a profile‐based location management technique to ensure the user's requirements, guaranteeing efficient resource utilization for a deployed cellular infrastructure 1–3. New packet‐based mobile broadband systems are positioned in this line.…”

“…In this context, in Ref. 2 we proposed a location update scheme based on the definition of an adaptive macro‐location area (macro‐LA), adapted to the mobility pattern of the terminals. The scheme is deployed on a network based on static LAs, by the definition of a macro‐LA per user, composed by several LAs, which tries to predict the user's movement.…”

Evaluation of the impact of mobility on typical KPIs used for the assessment of QoS in mobile networks: An analysis based on drive-test measurements

“…To date, both the scientific community and network operators mainly focus their studies on issues regarding the design and management of radio mobile networks as described in [2], [3], [4].…”
