Mission-critical user priority-based cooperative resource allocation schemes and apparatus for multi-layer next-generation public safety networks

摘要

A method and apparatus for allocating cooperative resources based on user priority in crisis missions for the next generation public safety communication network with a multi-layered structure are presented. The method for allocating cooperative resources based on user priority for crisis missions for a next-generation public safety network of a multi-layer structure proposed in the present invention is the step of identifying a user who needs CoMP and the corresponding attacker eNB through a CoMP scheduler and storing them in a CoMP set, LTE -R CoMP site in the network (S _R) Determining scheduling for the user (U_R ) of the LTE-R network for the attacker eNB and the remaining users in each CoMP site in the PS-LTE and LTE-M networks ( And_{determining scheduling for U P} and U_M ) according to a contention rule.
