El punto de partida de este proyecto es el de las redes inalámbricas móviles heterogéneas (incluyendo UMTS, GERAN y WLAN) con el objetivo de proporcionar calidad de servicio extremo a extremo para los servicios multimedia basados ​​en IP de una manera eficiente. En este marco, el objetivo de este proyecto es hacer frente a los diferentes problemas en diferentes niveles que conducen a profundizar en una solución global definitiva. En particular, los objetivos del proyecto se pueden establecer como:
 

  •  Analizar, evaluar y proponer arquitecturas de soporte de QoS extremo a extremo, con especial énfasis en la parte relativa a la gestión común de recursos radio (CRRM), la gestión de la calidad de servicio del núcleo de la red así como la arquitectura de interconexión entre las diferentes tecnologías de acceso radio.
     
  •  Analizar, elaborar y proponer estrategias de manejo de recursos en el marco de la integración de redes heterogéneas con la capacidad de proporcionar los objetivos de calidad, capacidad y cobertura de la manera más eficiente. Antes de definir estrategias CRRM es necesario analizar, desarrollar, proponer y evaluar estrategias de manejo de los recursos radio para cada una de las tecnologías (es decir, GSM / GPRS / EDGE, UMTS y WLAN). Los algoritmos propuestos tienen en cuenta el impacto de la gestión flexible del espectro y la asignación a través de algoritmos de gestión del espectro (SM).
     
  •  Demostrar, por medio de aplicaciones multimedia IP, la idoneidad de los elementos desarrollados a través de un banco de pruebas de laboratorio, que soporte los principales resultados del proyecto.
     

Por otra parte, ya que la correcta implementación de arquitecturas de redes heterogéneas, tales como RRM, CRRM y algoritmos de SM en gran medida depende de su viabilidad económica, este componente será muy tenido en cuenta en la investigación prevista, principalmente desde un punto de vista técnico-económico.
