Abstract

Esta solicitud proporciona un método de comunicación, un dispositivo de red de acceso, un dispositivo terminal, y un dispositivo de red básica. En un proceso en el que el dispositivo terminal se traspasa de un primer dispositivo de red de acceso a un segundo dispositivo de red de acceso, el segundo dispositivo de red de acceso puede aprender el primer progreso de servicio del primer dispositivo de red de acceso con base en un primer número de secuencia de un paquete de datos reenviado por el primer dispositivo de red de acceso, sin introducir información adicional de intercambio de progreso entre los dos dispositivos de red de acceso. El método incluye: un primer dispositivo de red de acceso, un primer paquete de datos y una primera información de indicación de un dispositivo de red básica, donde la primera información de indicación indica una secuencia del primer paquete de datos en al menos un paquete de datos; determina un primer número de secuencia de una primera capa de protocolo del primer paquete de datos con base en la primera información de indicación; y envía el primer paquete de datos a un dispositivo terminal.
