Abstract

Se dirigen sistemas y métodos para resolver la de-sincronización de cryptosync entre la red y las estaciones móviles (eNB) que puedan presentarse en movilidad. La de-sincronización se resuelve al reenviar el HFN y los Números de Secuencia de PDCP desde el eNB de origen hasta el eNB de destino. Para evitar reutilización de cryptosync para una clave dada, un desplazamiento de retroceso del valor inicial de COUNT se utiliza por el eNB de destino. Estos procedimientos no requieren una señalización por aire y el manejo del valor COUNT en la red es transparente para la estación móvil.
