R\u00e9sum\u00e9 de th\u00e8se :<\/strong>
\nLe r\u00e9seau de radio communications mobiles professionnelles (PMR), qui est utilis\u00e9 pour le fonctionnement de la s\u00e9curit\u00e9 publique, doit \u00e9voluer pour les solutions \u00e0 large bande pour satisfaire les demandes des utilisateurs \u00e0 l’avenir. Dans les technologies \u00e0 large bande actuels, Long Term Evolution (LTE), d\u00e9velopp\u00e9 par le 3GPP (3rd Generation Partnership Project), est consid\u00e9r\u00e9 comme l’un des candidats potentiels pour la prochaine g\u00e9n\u00e9ration de PMR.
\nMalgr\u00e9 le fait que la technologie LTE en charge la transmission de donn\u00e9es \u00e0 haute vitesse et prend en charge diff\u00e9rentes tailles de paquets en utilisant la modulation et le codage adaptatifs (AMC), le LTE n’est pas encore optimis\u00e9e pour la communication vocale \u00e0 bas d\u00e9bit, en particulier en cas d’utilisation LTE pour la radio communications mobiles professionnelles (PMR ) contexte.
\nPar cons\u00e9quent, dans cette th\u00e8se, nous pr\u00e9sentons des solutions pour renforcer la capacit\u00e9 de la voix de la technologie LTE dans le cadre PMR \u00e0 la fois la liaison montante et la transmission de liaison descendante. Les nouvelles propositions, bas\u00e9es sur la technologie de norme LTE existant avec des adaptations, permettent la r\u00e9duction de les frais g\u00e9n\u00e9raux de donn\u00e9es et les frais g\u00e9n\u00e9raux de contr\u00f4le sur LTE (VoLTE) dans le contexte PMR.<\/p>\n

Abstract :<\/strong>
\nThe Professional Mobile Radio (PMR) network, which is used for public safety operation, has to evolve to the broadband solutions to satisfy the user demands in the future. In the current broadband technologies, Long Term Evolution (LTE) standard, developed by the 3GPP (3rd Generation Partnership Project), is considered one of the potential candidates for the next generation of PMR.
\nDespite the fact that LTE supports high-speed data transmission and supports different packet sizes by using Adaptive Modulation and Coding (AMC), LTE is not yet optimized for low bit rate voice communication, especially in case of using LTE in Professional Mobile Radio (PMR) context.
\nTherefore, in this dissertation, we present several new solutions for enhancing the voice capacity of LTE in the PMR context for both uplink and downlink transmission. The new propositions, based on existent LTE standard technology with adaptations, allow reducing both control and data overhead issues of Voice over LTE (VoLTE) in PMR context. <\/p>\n","protected":false},"excerpt":{"rendered":"
