“…In any case, the differences both due to the network constraints in the wireless environment, and the specific system requirements, such as MC services or multicast transport, make these problems not directly comparable with this work. Specific studies related to optimizing IOPS settings are scarce, mainly limited to the works performed by Queis et al [20]- [22].…”

The adoption of commercial wireless technologies such as 4G/5G in public safety networks allows for new broadband services that could not be offered in this type of networks. Nevertheless, public safety networks are mission-critical systems that require the introduction of specific services in commercial wireless networks before this adoption. For instance, public safety networks require push-to-talk group communications or the possibility of operating in isolated mode, named by 3GPP the Isolated E-UTRAN Operation for Public Safety (IOPS). These requirements pose specific challenges that must be addressed, such as the placement of a local Evolved Packet Core (EPC) when a set of evolved Node B (eNB) must work in IOPS mode. In this paper, we analyze the implications of push-to-talk group communications and multicast in the local EPC placement problem for IOPS networks and propose an optimization algorithm that finds the best eNB where the local EPC should be co-located. Given the complexity of the problem, we also propose a heuristic algorithm to determine the optimal placement of the local EPC. Simulation results show the ability of our approach to adapt to different types of traffic with heterogeneous spatial distributions.

In many disaster scenarios, communication infrastructure fails to provide network services for both civilians and first responders. One solution is to have rapidly deployable mobile networks formed by interconnected base stations, that are easy to move, deploy, and configure. Such public safety-oriented networks are different from classical mobile networks in terms of scale, deployment, and architecture. In this context, we revisit the user association problem, for two main reasons. First, the backhaul, formed by the links interconnecting the base stations, must be accounted for when deciding on the association, since it may present a bottleneck with its limited bandwidth. Second, the mission-critical nature of the traffic imposes strict guaranteed bit rate constraints, that must be respected when associating users. Therefore, we propose a network-aware optimal association that minimizes the bandwidth consumption on the backhaul, while still respecting the stringent performance requirements.
