A measurement-based dynamic guard channel scheme for handover prioritization in cellular networks
Författare
Summary, in English
The introduction of guard channels in a cellular network is a method for giving priority to on-going calls by having channels exclusively reserved for handover purposes. Herein, an adaptive measurement-based dynamic guard channel scheme is introduced. The proposed scheme uses the number of on-going calls in adjacent cells and measurements of handover probabilities to determine the amount of guard channels to allocate in a cell. To improve the efficiency of the scheme, the calls are divided into groups depending upon mobility and latest visited cell, where separate measurements are performed for every single group. Simulations showed that the proposed scheme seems to be very efficient
