Initial RAT selection is a key Common RRM strategy, where users requiring service are to be efficiently allocated in the existing and available RATs. Although load balancing is a possible guiding allocation principle, sometimes it may not be convenient. This paper evaluates and compares a load balancing and a service-class RAT selection policy in order to discuss the suitability of the former in situations where different service-class mixings are present. Results indicate a tight dependency between this appropriateness and the mixing of demanding services.
