Les opérateurs de téléphonie consacrent beaucoup d'énergie et de ressources pour maintenir la signalisation sans laquelle aucun service n'est possible. Vu l'importance de la signalisation dans l'établissement des services des usagers, il nous ait apparu opportun de faire une étude sur celle-ci en vue d'apprécier comment elle est déployée dans certains réseaux d'opérateurs au Cameroun. Notre travail est organisé en trois parties. Nous présentons en premier lieu VIETTEL CMR S.A. et de CAMTEL en mettant l'action sur les architectures des réseaux de ces deux opérateurs de télécommunication mobile camerounais. Ensuite nous décrivons les protocoles du système de signalisation SIGTRAN/SS7 et enfin nous donnons quelques procédures d'établissement de services utilisées dans ces réseaux mobiles.
