Abstract

The invention proposes a method and device for aggregating a plurality of service data from a terminal equipment. A first network device in a radio access network encapsulates a plurality of service data from a machine terminal equipment into a non-access stratum data packet, performs a transmission process on the non-access stratum data packet to generate a processed signal and transmits the processed signal; and the signal is forwarded by a base station to a second network device in a core network, and the second network device recovers the non-access stratum data packet from the signal, extracts the plurality of service data from the non-access stratum data packet and then transmits the plurality of service data respectively to a corresponding destination server. With the solution of the invention, a signaling overhead and thus radio resources in a radio access network can be saved, and preferably a period of time for a terminal equipment to wait for a feedback can also be shorten so that the terminal equipment can enter a dormancy status or transmit new service data as soon as possible, thereby saving power consumption of the terminal equipment.
